I am taking a value and it is showing correctly (using it as a flag). Now we add a validation, but it does not show if it is meeting the validation. why? I dont know.
.aspx.cs
if (u.StatusRef.ToString().Equals('1'))
{
Email_Sent.Visible = true;
}
.aspx
<asp:Label ID="statusRef" runat="server"></asp:Label> <--- This shows the value '1'
<asp:Label ID="Email_Sent" runat="server" hidden="true">Status: You have notified the candidate to confirm references.</asp:Label>
Thanks,
EB.
You can try to use:
<asp:Label ID="Email_Sent" runat="server" Visible="False">
^^^^^^^^
Instead of hidden="true"

On client side button click event, I want to get control id that are place in Item template of Grid View. I tried this code but it doesn't work. Thanks
function buttonClicked(sender, args) {
var gv = $find('<%= GridView1.ClientID %>');
var textbox = $GridView1.findControl(gv.get_element().parentNode, "Textbox");
}
Here is the Gridview
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1"runat="server">
</asp:ScriptManager>
<div>
<asp:UpdatePanel ID="upTest" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="KurzDS" DataKeyNames="Id" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="Textbox" runat="server" Text="Textbox"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="Textbox1" runat="server" Text="Textbox1"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="btn" Text='btn' CommandArgument='<%# Eval("Id")%>' CommandName="btn" runat="server" CausesValidation="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
Thanks for including the GridView example. Now that I can see what you are attempting, I have a much better answer for you.
First, make a slight change to the button template, change out CommandArgument for OnClientClickand since you are using this button client side instead of posting back to the server, you can simplify it like this:
<asp:Button ID="btn" Text='btn' OnClientClick='<%# Eval("ID", "YourJavascriptFunction({0} - 1); return false;") %>' runat="server" CausesValidation="false" />
I have the click event call your JavaScript function and it sends in a parameter of the server side resolved id. Notice I subtract 1 first though. This is because the server side ASP.Net Eval function give the ID starting at 1. But, each of the ids that get generated for your text input elements start with a zero base.
Now look at the JavaScript function below.
// Clicking the first button sends in a 0, second sends in a 1, etc.
function YourJavascriptFunction(id) {
// each of the TextBox1 elements has an ASP.Net server side
// generated id that ends with GridView2_Textbox1_0,
// GridView2_Textbox1_1, etc.
let selectId = "input[id$='GridView2_Textbox1_" + id + "']";
// The text we use in the querySelector function states
// find the DOM element with a tag of "input" where the id
// ends with . . . The $ in id$= is the part that says the
// value must "end with"
let textBox1 = document.querySelector(selectId);
// Now that we have TextBox1 from the same row as the button,
// getting the value is easy.
alert(textBox1.value);
}
I left off a jQuery example as this querySelector command works in almost every browser including IE8 and above, so you shouldn't need jQuery for something this simple.
Let me know if I can help further.
I need to pass an argument (which comes from my database) from a radgrid view column to my javascript (which opens a dialog box window). However, I can't put the "bind("Id")" as a parameter from where I call the javascript as href.
In simpler words, I am looking for a way to pass <% Bind("Id")%> to the javascript, OpenMyWindow, call instead of the hardcoded, 111, right now.
<telerik:GridTemplateColumn UniqueName="Meet" DataField="Subject" HeaderText="Meet">
<ItemTemplate>
<div style="text-align: center">
<asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Bind("Subject") %>' href="javascript: OpenMyWindow(111);" Width="30%">
</asp:LinkButton>
</div>
</ItemTemplate>
</telerik:GridTemplateColumn>
When I try "OnClick" instead of "href", my popup dialog box closes instantly and doesn't stay opened.
Try using "OnClientClick" and return false from your javascript method to prevent post back.
Alternatively. You could use a method passing in the DataIten. Then output an anchor tag created anyway you like:
<%# formatOpener(Container.DataItem) %>
With code behind of:
protected string formatOpener(object item)
{
ObjectType myObj = (ObjectType)item;
return String.Format("<a href=\"javascript:OpenMyWindow({0});\" width=\"30%\"/>{1}</a>", myObj.ID, myObj.subject);
}
I think you don't need a LinkButton, you could achieve it with an asp:HyperLink (which renders as a a tag):
<asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("Subject") %>' NavigateUrl='<%# "javascript: OpenMyWindow(" + Eval("ID").ToString() + ");" %>'></asp:HyperLink>
Also, don't use Bind if you don't need it, for displaying purposes always use Eval.
User HyperLink control instead and try setting the NavigateUrl property of the HyperLink this way:
<asp:HyperLink ID="hlLink" runat="server" Text='<%# Bind("Subject") %>' NavigateUrl='<%#Eval("Id", "javascript: OpenMyWindow({0});")%>'>
hope it helps./.
I finally figured out and solved this issue. Actually, somebody told me on the other post that, CommandArgument is completely a server-side property and doesn't render any html attribute. So I can't change any button's attribute and fire click on it. I finally made "Id" come through the code behind and made it work.
aspx code
<telerik:GridButtonColumn UniqueName="Subject" DataTextField="Subject" HeaderText="Meeting">
<HeaderStyle Width="30%" />
<ItemStyle HorizontalAlign="Center" />
</telerik:GridButtonColumn>
Code Behind
var subjectLink = meetingRow["Subject"].Controls[0] as LinkButton;
subjectLink.Attributes.Add("onClick", "javascript: return OpenMyWindow('" + meetingId + "')");
<asp:datalist ID="Datalist1" runat="server"
Width="500px" >
<ItemTemplate>
<asp:Button ID="btnviewfullprofile" runat="server" Text="View Full Profile" ToolTip="Click for Full Profile of User" CommandArgument='<%#Eval("Uid")%>' CommandName="fullprofile" />
<asp:Button ID="sendinterest" runat="server" Text="Send Interest" CommandArgument='<%#Eval("Uid")%>' CommandName="sendinterest" />
<asp:Label ID="lblstatus" runat="server" Visible="False" ></asp:Label>
</ItemTemplate>
</asp:datalist>
text of label will change according to the value of status stored in database.
code for button
if (e.CommandName == "fullprofile")
{
int Id = int.Parse(e.CommandArgument.ToString());
Response.Redirect("~/FullProfile.aspx?Id=" + Id);
`enter code here` }
but what should i write for label so that text of label should change itself based on value of status stored in database
If I understand you correctly, you need to change the HTML to something like:
<asp:Label ID="lblstatus" runat="server" Visible="False"
Text='<%# Eval("DatabaseField") %>' />
You are already using this for the CommandArgument of the button. Obviously you need to replace 'DatabaseField' with the name of the field that you want to show as text. ASP.net will fill the Text attribute with the correct value from your datasource.
as you are binding commandargument of the button from database, same way you can bind the text property of the label
<asp:Label ID="lblstatus" runat="server" Visible="False" Text= '<%#Eval("textfield")%>' ></asp:Label>
If you need more advance control then you need to set them when items are getting bound see here fore details http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.datalist.itemdatabound.aspx
I have a gridview which has a few rows (each with a unique rowId), and each line has a FileUpload control, now everything works okay with FileUpload.
(my uploaded file database image can be seen below)
I have the download button, which also works okay, however I want to make this button invisible if no file exists for the corresponding row.
Nothing proper comes to my mind.
My button and FileUpload control:
<asp:TemplateField HeaderText="BatchList">
<EditItemTemplate>
<asp:ImageButton ID="ibt_Download" runat="server" src="Images/Download.png" CommandName="Download" CommandArgument='<%# Container.DataItemIndex %>' ></asp:ImageButton>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="UploadBatchList">
<HeaderTemplate>
<asp:Label ID="lbl_Header" ToolTip="Upload Batch List" runat="server" Text="UBL"></asp:Label>
</HeaderTemplate>
<EditItemTemplate>
<asp:FileUpload ID="fu_UploadBatchList" runat="server" />
<asp:Button ID="btn_Upload" runat="server" Text="Upload" OnClick="btn_Upload_Click" />
</EditItemTemplate>
</asp:TemplateField>
This is how it looks on my gridView
When gridview is first created the green dots must not be visible if a file has been uploaded before.
My file database:
You can check some property of the data item (DocName in your case) if it contains a value (it might not work when copy-pasted, I'm a little bit improvising):
<asp:Button ID="btn_Upload" runat="server"
Text="Upload"
Visible='<% DataBinder.Eval(Container.DataItem, "DocName") == null %>
OnClick="btn_Upload_Click" />
Or you can create a function that will evaluate the visibility. See Mastering ASP.NET DataBinding for more.
I'm using a FormView control to allow users to insert rows to the database. I want to validate these input fields, and as such have added a regular expression validation helper. Here's the markup:
<InsertItemTemplate>
<p>
Name:
<asp:TextBox ID="NameTextBox" runat="server" Text='<%# Bind("Name") %>' />
<asp:RegularExpressionValidator ValidationExpression="^[a-zA-Z0-9 ]*$" ControlToValidate="NameTextBox" ID="NameTextBoxValidator" runat="server" ErrorMessage="Must be alphanumeric characters and spaces"></asp:RegularExpressionValidator>
</p>
<p>
Location:
<asp:TextBox ID="LocationTextBox" runat="server"
Text='<%# Bind("Location") %>' />
</p>
<p>
<asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True"
CommandName="Insert" Text="Insert" />
</p>
</InsertItemTemplate>
However, when I click InsertButton the page refreshes and I get an error from SQL Server saying it can't insert a NULL value, the validator isn't getting used at all.
How can I fix this?
I assume that the user entered no text and the database does not allow null values.
A RegularExpressionValidator will not validate empty controls. So you need to provide also a RequiredFieldValidator.
The validation will not fail if the input control is empty. Use the
RequiredFieldValidator control to make the field required.

Not much info here, but I'll venture a guess:
Check to make sure you don't have anything happening OnLoad that's blanking things out. If you do have an OnLoad make sure it only fires when IsPostback is false.
