I have a simple user control that will be displayed numerous times on the page. So i have a panel which a loop over a dataset, creating the UC, populating a textbox and a checkbox, and then adding it to the panel.
The panel adds the UC but neither the textbox value nor the checkbox is changed...
foreach (Issue iss in Case.Issues)
{
Comments comment = (Comments)LoadControl("~/UserControls/Comments.ascx");
comment .ID = "Comment" + iss.IssueDetail.quality_control_issue_id.ToString();
comment .Populate(iss);
QCComments_list.Controls.Add(comment );
}
Do i have to do this on pre-render or Onit of the page or there a way of refreshing the controls of the UC?
Here's the UC markup. very simple.
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="ROI_Comments.ascx.cs" Inherits="QualityControl_UserControls.ROI_Comments" %>
<!-- Field -->
<div id="ROI_Comment_DIV" class="field">
<label>Corrections</label>
<input type="text" runat="server" id="comtxt" name="comtxt" />
<asp:CheckBox ID="issue_critical" runat="server" Text="Critical" />
<asp:Button runat="server" id="SaveButton" Text="Add Comment" OnClientClick="SaveComment(this);return false;" />
<asp:Button runat="server" id="ROICancelButton" Text="Cancel" OnClientClick="return false;" />
<asp:HiddenField runat="server" ID="hIssueID" />
</div>
<!-- /Field -->
and the .cs
public partial class ROI_Comments : System.Web.UI.UserControl
{
public ROI_Comments()
{
}
public void Populate(cQuality_Control_Issue _comment)
{
try
{
hIssueID.Value = _comment.IssueDetail.quality_control_issue_id.ToString();
comtxt.Value = _comment.IssueDetail.quality_control_issue_description;
comtxt.Disabled = true;
issue_critical.Checked = _comment.IssueDetail.quality_control_issue_critical;
issue_critical.Enabled = false;
ROICancelButton.Text = "Delete";
}
catch(Exception ex)
{}
}
}
There's nothing obviously wrong from what you have shown but there could be a null reference exception occurring before the values are set. You would not know about it because of the empty try/catch block. Its never a good idea to use an empty try/catch because you would have no idea if an exception is occurring.

I'm having trouble trying to clear these banking and routing numbers that are in a textbox on an aspx page. I've seen it used where they would just specify the ID of the textbox and do a textbox.text = String.Empty(). But that doesn't seem to work here. Maybe I'm using the wrong ID?? I also tried using JQuery .val("") but that didn't seem to work either.
Here's the code, i'd like to clear both Routing and Account text fields on click of a button:
<div id="DivUser1BankInfo" class="labelAndTextboxContainer">
<div class="labelContainer">
<asp:Label CssClass="rightFloat" ID="User1LabelRoutingNumber" runat="server" Text="Routing #:"></asp:Label><br />
</div>
<div class="textboxContainer">
<asp:TextBox ID="User1TextRoutingNumber" CssClass="leftFloat " runat="server" Font-Size="Smaller" Width="180px"
Text='<%# Bind("User1BankRoutingNumber") %>'
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>' /><br />
</div>
<div class="labelContainer">
<asp:Label CssClass="rightFloat" ID="User1LabelAccountNumber" runat="server" Text="Account #:"></asp:Label><br />
</div>
<div class="textboxContainer">
<asp:TextBox ID="User1TextAccountNumber" CssClass="leftFloat " runat="server" Font-Size="Smaller" Width="180px"
Text='<%# Bind("User1BankAccountNumber") %>'
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>' /><br />
</div>
<button type="button" id="clearButton1">Clear</button>
<div class="button">
<asp:Button ID="User1ClearBankInfo" runat="server" Text="Reset"
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>' OnClick="clearFields_btn"/><br />
</div>
The OnClick= "clearFields_btn" code behind =
protected void clearFields_btn(object sender, EventArgs e)
{
}
Thanks for any help!
I haven't worked with ASP.NET in a little while, but I think you may want the OnClientClick event, not OnClick. OnClientClick is for client-side code (your jQuery/JavaScript) and OnClick is for server-side code (your C# or VB.NET).
You'd also want your OnClientClick event method to return false, or the server-side code will also fire.
So I think you want something like:
<asp:Button ID="User1ClearBankInfo" runat="server" Text="Reset"
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>
OnClientClick="clearText();"/>
And then clearText would look like this:
<script>
function clearText()
{
//our two IDs
$('input[id*="User1TextRoutingNumber"]').each(function(index) {
$(this).val('');
});
$('input[id*="User1TextAccountNumber"]').each(function(index) {
$(this).val('');
});
return false;
}
</script>
EDIT: shoot, I see my mistake. Fixed the code to clear the text of the textbox, not the button ("this").
Edit: removed the space from the "clear" text val.
EDIT: Made search a little more flexible, less dependent on GridView or no GridView.
Try this
<script>
var clear = function(textboxID){$('input[id*=' + textboxID + ']').val('');};
return false;
</script>
<button id="btClearText" onclick="javascript:return clear('txtName');">
but if you need a more specific answer then please post more information
You need something like this. Assuming you want a client side solution (not very clear from your question).
<script type="text/javascript">
function clearTextBox() {
document.getElementById("<%= User1TextRoutingNumber.ClientID %>").value = "";
//or
$("#<%= User1TextRoutingNumber.ClientID %>").val("");
}
</script>
The <%= User1TextRoutingNumber.ClientID %> will ensure you get the correct ID for javascript/jQuery.
A server side solution would be:
protected void clearFields_btn(object sender, EventArgs e)
{
for (int i = 0; i < GridView1.Rows.Count; i++)
{
TextBox tb = GridView1.Rows[i].FindControl("User1TextAccountNumber") as TextBox;
tb.Text = "";
}
}
Sorry to post perhaps a silly problem here, but I'm at my wits end with it. I have a hidden field with a button inside an update panel like so:
<asp:UpdateProgress runat="server" ID="updprCompLines" AssociatedUpdatePanelID="updpanCompLines">
<ProgressTemplate>
<img src="../Images/ajax-loader.gif" alt="Please wait..." /> </ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel runat="server" ID="updpanCompLines" UpdateMode="Conditional">
<%--<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnFillMembers" />
</Triggers>--%>
<ContentTemplate>
<div>
<asp:HiddenField ID="hdnField" runat="server" />
<asp:Button ID="btnFillMembers" runat="server" style="display:none;"
Text="DummyButton" onclick="btnFillMembers_Click" />
</div>
The update panel also contains a gridview and inside my gridview I have a link button:
<ItemTemplate>
<asp:LinkButton ID="lkbtBenefName" runat="server" Text='<%#Eval("COMPETENCE_CODE") %>'
OnClientClick='<%#Eval("COMPETENCE_LINE_ID", "return SelectedCompetence({0})") %>'/>
</ItemTemplate>
The call is to a JS function that is supposed to call the above button:
<ajaxToolkit:ToolkitScriptManager runat="Server" EnablePartialRendering="true" ID="ScriptManager1" EnablePageMethods="true"/>
<script type="text/javascript">
function SelectedCompetence(CompetenceLineId) {
document.getElementById('<%= hdnField.ClientID %>').value = CompetenceLineId;
var clickButton = document.getElementById('<%= btnFillMembers.ClientID %>');
clickButton.click();
}
</script>
Button click event method:
protected void btnFillMembers_Click(object sender, EventArgs e)
{
lblGvMemError.Text = "";
lblGvMemError.ForeColor = Color.Red;
if (hdnField.Value != null || hdnField.Value.ToString() != "")
{
try
{
int CompLineId = Convert.ToInt32(hdnField.Value);
GetSelectedCompLineMembers(CompLineId);
}
catch (Exception ex)
{
lblGvMemError.Text = "Error: " + ex.Message;
}
}
updpanCompLinesMembers.Update();
}
The problem is that while debugging, it never runs the click event and it doesn't give any error messages either. I don't understand, I have a similar form where this works; I don't get why it doesn't here... Any help please?
Have you confirmed that SelectedCompetence is being called via an alert or similar? Additionally, have you made sure that the clickButton variable is being assigned to successfully?
I know this isn't an answer, but don't yet have the reputation to comment, and sometimes it's the easy stuff so maybe this will help! :)
I've got a ValidationSummary and SuccessLabel in the MasterPage
When the SuccessLabel has detail in it, and then the ValidationSummary then fails validation I want it to hide the SuccessLabel and only show the ValidationSummary.
<div id="ApplicationStatus" class="ValidationSummaryContainer">
<asp:Label ID="StatusLabel" CssClass="SuccessSummary" runat="server"
Visible="false"></asp:Label>
<asp:Label ID="WarningLabel" CssClass="WarningSummary" runat="server"
Visible="false"></asp:Label>
<asp:ValidationSummary ID="ErrorValidationSummary" runat="server"
CssClass="ValidationSummary" DisplayMode="List" />
<asp:CustomValidator ID="ErrorCustomValidator" runat="server"></asp:CustomValidator>
</div>
<div id="ApplicationContent" class="ApplicationContentContainer">
<asp:ContentPlaceHolder ID="MainContent" runat="server">
</asp:ContentPlaceHolder>
</div>
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
StatusLabel.Text = "Successfully loaded record";
}
}
<asp:Content ID="Content1" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">
<asp:Textbox ID = "Text1" runat="server"/>
<asp:RequiredFieldValidator id="InputTextBoxRequiredFieldValidator" runat="server"
ControlToValidate="Text1" Visible="false" CssClass="InlineNoWrap" Enabled="true">
</asp:RequiredFieldValidator>
<asp:Button ID = "Button1" runat="server" Text="Submit"/>
</asp:Content>
I'm trying to find a way in JavaScript to catch the validation error and hide the StatusLabel.
I don't want to have to put a javascript function on every button on every page that uses the MasterPage.
Thanks,
Alex
How about something like this:
protected void Submit(object sender, EventArgs e)
{
if (IsValid)
{
StatusLabel.Visible = true;
}
else
{
StatusLabel.Visible = false;
}
}
Your validation code are totally miss lot of fields.
ok now we are going your pint .
Set visible false in your label for page load event
then success time add the label text ,and set visible true
you miss control to validate and validationgroup and display fields
please see this sample
A Default.aspx page has some controls. Some controls visibility depends upon conditions. Here, what is tend to accomplish is change the visible property at runtime depending upon the conditional value.
Sampel Markup (Default.aspx in Static Mode)
<div id="DivBtnImgCopy" runat="server" Visible = "True">
<asp:ImageButton ID="BtnImgCopy" CssClass="image" ToolTip="Copy Mode" ImageUrl="img/tlb_img_copy.gif" runat="server" OnClientClick="CopyImage(); SelectButton(this,true);return false;" />
</div>
What I tried is write a method in code behind file and tried to get value from that method to set visible property to true or false.
CodeBehindFile (Default.aspx.cs)
protected bool ShowHideButton()
{
bool bStatus = false;
try
{
if (sCondition == "false")
{
bStatus = false;
}
else if (sCondition == "true")
{
bStatus = true;
}
return bStatus;
}
catch { }
}
Sample Markup (Default.aspx in Dynamic Mode)
<div id="DivBtnImgCopy" runat="server" visible = "<% =ShowHideButton() %>">
<asp:ImageButton ID="BtnCopy" ToolTip="Copy Mode" ImageUrl="img/tlb_img_copy.gif"
runat="server" />
</div>
But, Getting below error:
Cannot create an object of type 'System.Boolean' from its string representation '<%=ShowHideButton() %>' for the 'Visible' property.
Any solution or work-around to accomplish this task.
Need Help.
Fastest way to do it is having your ShowHideButton return a bool instead of a string ; then :
<%
DivBtnImgCopy.Visible = ShowHideButton();
%>
<div id="DivBtnImgCopy" runat="server" >
<asp:ImageButton ID="BtnCopy" ToolTip="Copy Mode" ImageUrl="img/tlb_img_copy.gif"
runat="server" />
</div>
Cleanest way would be to include DivBtnImgCopy.Visible = ShowHideButton(); in the prerender event handler of your page
I am not sure of what visible does.
If you want not to render the div at all, you could wrap your in a <% if %> :
<% if(ShowHideButton()) { %>
<div id="DivBtnImgCopy" runat="server">
<asp:ImageButton ID="BtnCopy" ToolTip="Copy Mode" ImageUrl="img/tlb_img_copy.gif"
runat="server" />
</div>
<% } %>
I have a repeater and each item contains a button which should redirect to another page and also pass a value in the query string.
I am not getting any errors, but when I click the button, the page just refreshes (so I am assuming a postback does occur) and does not redirect. I think that for some reason, it isn't recognizing the CommandName of the button.
Repeater code:
<asp:Repeater ID="MySponsoredChildrenList" runat="server" OnItemDataBound="MySponsoredChildrenList_ItemDataBound" OnItemCommand="MySponsoredChildrenList_ItemCommand">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<br />
<div id="OuterDiv">
<div id="InnerLeft">
<asp:Image ID="ProfilePic" runat="server" ImageUrl='<%#"~/Resources/Children Images/" + String.Format("{0}", Eval("Primary_Image")) %>'
Width='300px' Style="max-height: 500px" /></div>
<div id="InnerRight">
<asp:HiddenField ID="ChildID" runat="server" Value='<%# DataBinder.Eval(Container.DataItem, "Child_ID") %>'/>
<span style="font-size: 20px; font-weight:bold;"><%# DataBinder.Eval(Container.DataItem, "Name") %>
<%# DataBinder.Eval(Container.DataItem, "Surname") %></span>
<br /><br /><br />
What have you been up to?
<br /><br />
<span style="font-style:italic">"<%# DataBinder.Eval(Container.DataItem, "MostRecentUpdate")%>"</span>
<span style="font-weight:bold"> -<%# DataBinder.Eval(Container.DataItem, "Update_Date", "{0:dd/MM/yyyy}")%></span><br /><br /><br />Sponsored till:
<%# DataBinder.Eval(Container.DataItem, "End_Date", "{0:dd/MM/yyyy}")%>
<br /><br />
<asp:Button ID="ChildProfileButton" runat="server" Text="View Profile" CommandName="ViewProfile" />
</div>
</div>
<br />

<div id="SeparatorDiv">
</div>
</SeparatorTemplate>
</asp:Repeater>
C# Code behind:
protected void MySponsoredChildrenList_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
// Stuff to databind
Button myButton = (Button)e.Item.FindControl("ChildProfileButton");
myButton.CommandName = "ViewProfile"; }
}
protected void MySponsoredChildrenList_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "ViewProfile")
{
int ChildIDQuery = Convert.ToInt32(e.Item.FindControl("ChildID"));
Response.Redirect("~/ChildDescription.aspx?ID=" + ChildIDQuery);
}
}
I am new to using repeaters so it's probably just a rookie mistake. On a side note: is there a better way of obtaining the ChildID without using a hidden field?
EDIT: Using breakpoints; the ItemDatabound event handler is being hit, but the ItemCommand is not being entered at all
You need to set MySponsoredChildrenList_ItemDataBound as protected. Right now, you have just 'void' which by default is private, and is not accessible to the front aspx page.
Another way is to use the add event handler syntax from a function in your code behind, using the += operator.
Either way, the breakpoint will now be hit and our code should mwork.
EDIT: So the above solved the compilation error but the breakpoints are not being hit; I've ran some tests and am able to hit breakpoints like this:
Since I do not know how you are databinding, I just added this code to my code-behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
MySponsoredChildrenList.DataSource = new List<object>() { null };
MySponsoredChildrenList.DataBind();
}
}
Note: If you DataBind() and ItemDataBound() is called on every postback, it will wipe out the command argument, which is potentially what you are seeeing; so if you always see [object]_ItemDataBound() breakpoint hit, but never [object]_ItemCommand(), it is because you need to databind only on the initial page load, or after any major changes are made.
Note also the method MySponsoredChildrenList_ItemCommand doesn't work:
protected void MySponsoredChildrenList_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "ViewProfile")
{
int ChildIDQuery = Convert.ToInt32(e.Item.FindControl("ChildID"));
Response.Redirect("~/ChildDescription.aspx?ID=" + ChildIDQuery);
}
}
When you do FindControl, you need to cast to the correct control type, and also make sure to check for empty and null values before converting, or else you will possibly have errors:
protected void MySponsoredChildrenList_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "ViewProfile")
{
int childId = 0;
var hiddenField = e.Item.FindControl("ChildID") as HiddenField;
if (null != hiddenField)
{
if (!string.IsNullOrEmpty(hiddenField.Value))
{
childId = Convert.ToInt32(hiddenField.Value);
}
}
if (childId > 0)
{
Response.Redirect("~/ChildDescription.aspx?ID=" + childId);
}
}
}
Hope this helps - if not, please post additional code for the "full picture" of what is happening, so we can see where else you might have a problem.
I think on the repeater you need to add
OnItemDataBound="MySponsoredChildrenList_ItemDataBound"
Not 100% sure, but could be the same for the ItemCommand.
--
In regards to obtaining the ChildID. Add a CommandArgument to the button in the repeater, and set it in the same way, <% Eval("ChildID") %>. This can the be obtained using e.CommandArgument.
Try this.. Add an attribute to item row
row.Attributes["onclick"] = string.Format("window.location = '{0}';", ResolveClientUrl(string.Format("~/YourPage.aspx?userId={0}", e.Item.DataItem)) );
or You can do like this also
<ItemTemplate> <tr onmouseover="window.document.title = '<%# Eval("userId", "Click to navigate onto user {0} details page.") %>'" onclick='window.location = "<%# ResolveClientUrl( "~/YourPage.aspx?userId=" + Eval("userid") ) %>"'> <td> <%# Eval("UserId") %> </td> </tr> </ItemTemplate>
