I am trying to have the clicked on(selected) ListView item be highlighted. However what is currently happening is the last selected item is being highlighted instead.
Here is my asp.net code:
<asp:ListView ID="UsersListView" AutoPostBack="true" runat="server" OnSelectedIndexChanging="UsersListView_SelectedIndexChanging" OnSelectedIndexChanged="UsersListView_SelectedIndexChanged" >
<LayoutTemplate>
<table id="itemPlaceholderContainer" runat="server" border="0" style="">
<tr>
<td id="itemPlaceholder" runat="server">
</td>
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr runat="server">
<td>
<asp:LinkButton ID="UserNameLinkButton" CommandName="Select" runat="server" Text='<%# Container.DataItem %>'/>
</td>
</tr>
</ItemTemplate>
<SelectedItemTemplate>
<tr runat="server" style="background-color: #336699;">
<td>
<asp:LinkButton ID="UserNameLinkButton" CommandName="Select" runat="server" Text='<%# Container.DataItem %>' BackgroundColor="#336699" ForeColor="White" />
</td>
</tr>
</SelectedItemTemplate>
</asp:ListView>
Here is my C# code beside:
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
List<string> users = new List<string>()
{
"Gary",
"Joe",
"Brian"
};
UsersListView.DataSource = users;
UsersListView.DataBind();
}
}
protected void UsersListView_SelectedIndexChanging(object sender, ListViewSelectEventArgs e)
{
UsersListView.SelectedIndex = e.NewSelectedIndex;
}
protected void UsersListView_SelectedIndexChanged(object sender, EventArgs e)
{
}
Thank you for your help.
You have to use OnCommand for link button or use ListViewItemCommand and pass Item.DisplayIndex as argument to linkButton attribute CommandArgument while you are selecting item and in your case when link button is not to highlight because you are focusing on selecting not over LinkButton.So do your code on Server Side for HighLight Item Button.
Aspx
<asp:ListView ID="UsersListView" AutoPostBack="true" runat="server" OnSelectedIndexChanged="UsersListView_SelectedIndexChanged" OnItemCommand="UsersListView_ItemCommand" OnSelectedIndexChanging="UsersListView_SelectedIndexChanging">
<LayoutTemplate>
<table id="itemPlaceholderContainer" runat="server" border="0" style="">
<tr>
<td id="itemPlaceholder" runat="server">
</td>
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr runat="server">
<td>
<asp:LinkButton ID="UserNameLinkButton" CommandName="Select" OnCommand="UserNameLinkButton_Command" CommandArgument="<%# Container.DisplayIndex %>" runat="server" Text='<%# Container.DataItem %>'/>
</td>
</tr>
</ItemTemplate>
<SelectedItemTemplate>
<tr runat="server">
<td>
<asp:LinkButton ID="UserNameLinkButton" CommandName="Select" CommandArgument="<%# Container.DisplayIndex %>" runat="server" Text='<%# Container.DataItem %>' ForeColor="White" />
</td>
</tr>
</SelectedItemTemplate>
</asp:ListView>
cs(Code)
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
List<string> users = new List<string>()

I have below list view , how can i hide column by code behind ?
<asp:ListView ID="AuditLogListView" runat="server" OnItemCreated="AuditLogListView_ItemCreated">
<LayoutTemplate>
<table class="table table-striped table-bordered small">
<tr class="table-secondary">
<th id="BlockHeader" runat="server" style="white-space: normal;">
<asp:Literal ID="BlockHeaderLiteral" runat="server" Text="<%$ Resources:AppResources, AuditInformationBlockHeader %>" />
</th>
</tr>
<asp:PlaceHolder runat="server" ID="ItemPlaceholder"></asp:PlaceHolder>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td id="BlockStatus" runat="server">
<%# Eval("BlockStatus")%>
</td>
</tr>
</ItemTemplate>
After binding data with list view i tried below code behind but with this header text only hide but column still can still visible
if (groupOrBlockValue == 'W')
{
AuditLogListView.FindControl("BlockHeader").Visible = false;
AuditLogListView.FindControl("BlockHeaderLiteral").Visible = false;
//AuditLogListView.FindControl("BlockStatus").Visible = false;
}
Missing part of the list view?
With this:
<asp:ListView ID="LstMarks" runat="server" DataKeyNames="ID" >
<ItemTemplate>
<tr style="">
<td><asp:Textbox ID="Course" runat="server" Text='<%# Eval("Course") %>' /></td>
<td><asp:Textbox ID="Mark" runat="server" Text='<%# Eval("Mark") %>' Width="30px"/></td>
<td>
<asp:CheckBox ID="DoneLabs" runat="server" Checked = '<%# Eval("DoneLabs") %>' Width="30px"/>
</td>
</tr>
</ItemTemplate>
<LayoutTemplate>
<table id="itemPlaceholderContainer" runat="server" border="0" class="table">
<tr runat="server" style="">
<th runat="server" >Course</th>
<th runat="server">Mark</th>
<th id= "LabW" runat="server" >Completed Lab Work</th>
</tr>
<tr id="itemPlaceholder" runat="server">
</tr>
</table>
</LayoutTemplate>
</asp:ListView>
<br />
<br />
<asp:Button ID="cmdHide" runat="server" Text="Hide Lab check box" OnClick="cmdHide_Click" />
So note in the layout, we added a "id" = LabW - that lets you hide the header.
so, a simple button that would toggle (hide/show) the lvColum, then this works:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
using (SqlCommand cmdSQL = new SqlCommand("SELECT * from StudentCourses",
new SqlConnection(Properties.Settings.Default.TEST4)))
{
cmdSQL.Connection.Open();
LstMarks.DataSource = cmdSQL.ExecuteReader();
LstMarks.DataBind();
}
}
}
protected void cmdHide_Click(object sender, EventArgs e)
{
Control ctrHeader = LstMarks.FindControl("LabW");
ctrHeader.Visible = !ctrHeader.Visible;
foreach (ListViewItem lvRow in LstMarks.Items)
{
CheckBox ckBox = (CheckBox)lvRow.FindControl("DoneLabs");
ckBox.Visible = !ckBox.Visible;
}
}
So, we get this:
And clicking on the button, we get this:
And both the values changed - they persist - even when you click again (to toggle and show the hidden columns).
Edit: =====================================================
So, say this markup:
<asp:ListView ID="AuditLogListView" runat="server"
OnItemCreated="AuditLogListView_ItemCreated">
<LayoutTemplate>
<table class="table table-striped table-bordered small">
<tr class="table-secondary">
<th id="BlockHeader" runat="server" style="white-space: normal;">
<asp:Literal ID="BlockHeaderLiteral" runat="server" Text="Hotel Name" />
</th>
</tr>
<asp:PlaceHolder runat="server" ID="ItemPlaceholder"></asp:PlaceHolder>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td id="BlockStatus" runat="server">
<%# Eval("BlockStatus")%>
</td>
</tr>
</ItemTemplate>
</asp:ListView>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
And code behind button to hide is this:
protected void Button1_Click(object sender, EventArgs e)
{
Control ctrHeader = AuditLogListView.FindControl("BlockHeaderLiteral");
ctrHeader.Visible = !ctrHeader.Visible;
foreach (ListViewItem lvRow in AuditLogListView.Items)
{
Control BlockStat = (Control)lvRow.FindControl("BlockStatus");
BlockStat.Visible = !BlockStat.Visible;
}
}
At which event have you written this code?
Required this code in the OnDataBound event. And in your code this event missing.
<asp:ListView ID="AuditLogListView" runat="server" OnItemCreated="AuditLogListView_ItemCreated" OnDataBound="AuditLogListView_DataBound">
<asp:Literal ID="BlockHeaderLiteral" runat="server" Text="<%$ Resources:AppResources, AuditInformationBlockHeader %>" /><asp:PlaceHolder runat="server" ID="ItemPlaceholder"></asp:PlaceHolder>
C# Code:
protected void AuditLogListView_DataBound(object sender, EventArgs e)
{AuditLogListView.FindControl("BlockHeaderLiteral").Visible = false;}
I have a method that generates accordionpanes and panels and inside each accordionpane I create a button. This methode I use it in the listviewselectedindexchanged method to create the order object and fillup the body panel
protected void PanelCreator(Order order, List<Panel> pnllist)
{
Panel panelHead = new Panel();
panelHead.ID = "pH" + order.product;
panelHead.CssClass = "cpHeader";
//Add Label inside header panel to display text
Label lblHead = new Label();
lblHead.ID = order.product;
lblHead.Text = order.productName + " €" + order.priceValue;
panelHead.Controls.Add(lblHead);
//Create Body Panel
Panel panelBody = new Panel();
panelBody.ID = "pB" + order.product;
panelBody.CssClass = "cpBody";
AccordionPane ap = new AccordionPane();
foreach (Panel p in pnllist)
{
panelBody.Controls.Add(p);
}
Button btn = new Button();
btn.ID = "btn" + order.product;
btn.Text = "Toevoegen";
btn.Click += new EventHandler(btn_Click);
panelHead.Controls.Add(btn);
ap.ID = "ap" + order.product;
ap.HeaderContainer.Controls.Add(panelHead);
ap.ContentContainer.Controls.Add(panelBody);
accMenu.Panes.Add(ap);
}
I am trying to reach each buttons click event but don't know how to do it.
I have this method as for the click event to test a label inside the updatepanel but not working
protected void btn_Click(object sender, EventArgs e)
{
nameLabel.Text = "testinf";
}
this is my aspx page:

You need to store your button creation data in ViewState for creating these controls in page-load event, after that button click will be processed correct.
Order class should be marked as Serializable
public Order SelectedOrder
{
get
{
return ViewState["StoredOrder"] == null ? (Order)ViewState["StoredOrder"] : null;
}
}
protected void Page_Load(object sender, EventArgs e)
{
if (SelectedOrder != null)
{
PanelCreator(SelectedOrder);
}
}
protected void listviewselectedindexchanged(object sender, System.EventArgs e)
{
// I am not sure how you got order in this event, you should use your version of code, but idea is the same
ViewState["StoredOrder"] = sender as Order;
PanelCreator(SelectedOrder);
}
I am trying to get image inside LinkButton in Repeater and wanted to change image Src but it does not changing image UI side.
HTMl Code:
<asp:Repeater ID="Repeater" runat="server" OnItemCommand="Repeater_ItemCommand" >
<HeaderTemplate>
<table c>
<tr>
<th>
<asp:LinkButton ID="lbtnC1" CommandName="Col1" runat="server">Column1 <asp:Image id="imgStamp" ClientIDMode="AutoID" runat="server" style="vertical-align:middle;padding-left:3px" /></asp:LinkButton>
</thalign>
<th>
<asp:LinkButton ID="lbtnC2" runat="server"
CommandName="Col2">Column2 <asp:Image id="imgStamp" ClientIDMode="AutoID" runat="server" style="vertical-align:middle;padding-left:3px" /></asp:LinkButton></th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:Literal ID="C1Value" runat="server" />
</td>
<td>
<asp:Literal ID="C2Value" runat="server" />
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
C# Event
protected void Repeater_ItemCommand(object source, RepeaterCommandEventArgs e)
{
LinkButton linkButton = e.CommandSource as LinkButton;
HtmlImage image = linkButton.Controls[0] as HtmlImage;
if (e.CommandName == "Col1")
{
image.Src = Page.ResolveUrl("~/arrow-down-white.gif");
}
}
Change it to HtmlImage image = linkButton.Controls[1] as HtmlImage;
I believe (but not 100% sure) that the first control is a Literal.
By doing this i'm able to solve my issue.
protected void Repeater_ItemCommand(object source, RepeaterCommandEventArgs e)
{
Image imgStamp = Repeater.Controls[0].Controls[0].FindControl("imgStamp") as Image;
imgStamp.ImageUrl = Page.ResolveUrl("URL");
}
I've just taken over a C#/.NET project last touched a few years ago with with the task of updating it and including more functionality. I have no experience with the platform and so am struggling to fix this error.
The system is currently live (and works), but I've gotten a copy running on my machine and I get the following error which I cannot seem to figure out to get it up and running:
Compiler Error Message: CS0120: An object reference is required for the non-static field, method, or property '<ProjectName>.<PageName>.System'
Source Error:
Line 195:
Line 196: private static System.Reflection.MethodInfo #__PageInspector_LoadHelper(string helperName) {
Line 197: System.Type helperClass = System.Type.GetType("Microsoft.VisualStudio.Web.PageInspector.Runtime.WebForms.TraceHelpers, Microsoft" +
Line 198: ".VisualStudio.Web.PageInspector.Tracing, Version=2.0.0.0, Culture=neutral, Publi" +
Line 199: "cKeyToken=b03f5f7f11d50a3a", false, false);
I've established from other questions that this error is normally caused when using non-static fields and methods incorrectly like this or this, but in my case it seems to be coming from a temporary file, which I have no control over?

I think, you are having same name for both class and namespace, could you please check, it might be the cause of this issue.
As, usual, I found the solution to my own problem (two cups of coffee and eight full hours of sleep later - not in that order).
The problem was that in Admin.aspx, the first div with id=System forced the Admin.aspx.designer.cs file to generate a System.Web.UI.HtmlControls.HtmlGenericControl variable called System.
This caused some sort of confusion for the compiler (is that even an actual thing?) because of the System namespace.
This was a good lesson in what not to do.
I have a ASP.NET web form where I have few checkboxes etc to make SearchCriteria object. When I click submit button I ask repeater1 to shew some records according to SearchCriteria. Inside repeater1 I have user control with updatepanel and another one repeater (ChildRepeater).
My problem: when I click send on the button after postback I lose all the data from form (eg that checkboxes was checked). Page is loading default values, but in my code I load default (all checkboxes checked) only if(!IsPostBack).
Of course I have "EnableViewState=true" in .aspx, I also tried to save data from form in session, but it also does not work (default values rewrite this settings).
When I have only one repeater (repeater1) my form after postback had all the data I put on it, so I think that there is some problem in updatepanel, but I don't know where exactly.
Could you explain me why my form loses data after page reload? I can't see any mistake..
At the bottom are my files but I have n-tier architecture so... i put only necessary files from View/BLL (DAL and sql connection works fine)
Here you have a screen how it looks: screen

It is because when you post back your update panel it refreshes a part(which is surrounded with update panel) of the page, so all data that was on that pannel is lost you can save all data that you need in ViewState
protected void UpdatePanelClick_OnClick(object sender, EventArgs e)
{
List<int> checkedIds = new List<int>();
//working with grid saving ids on list
ViewState["saveUpdatePanelData"] = checkedIds;
}
than on pageload after postback you can get this data and initialize
protected void Page_Load(object sender, EventArgs e)
{
if (ViewState["saveUpdatePanelData"]!= null)
{
checkedIds = ViewState["saveUpdatePanelData"] as List<int>;
}
}
it is how ViewState works.
