How to set Item index in a Repeater Column with Hidden Fields in asp.net.
I wrote the following code but it does not show the index value in hidden field.<ItemTemplate>
<tr>
<td>
<asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Container.ItemIndex+1 %>' />
<%--<asp:HiddenField ID="hfIndex" runat="server" Value='<%#Container.ItemIndex+1 %>' />--%>
</td>
<td>
<asp:Label ID="lblExpenseGLCode" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "ACM_ACCOUNT_CODE")%>'></asp:Label>
</td>
<td>
<asp:Label ID="lblAccountGLDescription" runat="server" Tex开发者_C百科t='<%# DataBinder.Eval(Container.DataItem, "ACM_ACCOUNT_DESC")%>'></asp:Label>
</td>
</tr>
</ItemTemplate>
I can't see anything necessarily wrong with the itemtemplate, it would probably help if you provide the entire repeater code as a direct copy / paste in case there area any other errors.
Another approach you can take is to add a repeater data item bound event and then capture the hiddenfield in the event. Once you have the hidden input you can simply set it's value.
Repeater code:
<asp:Repeater ID='myRepeater' runat="server" OnItemDataBound='myRepeater_OnItemDataBound'>
<ItemTemplate>
<asp:HiddenField ID='myHidden' runat="server" />
</ItemTemplate>
</asp:Repeater>
And the code behind event:
protected void myRepeater_OnItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
var myHidden = (HiddenField)e.Item.FindControl("myHidden");
myHidden.Value = e.Item.ItemIndex.ToString();
}
}
it has to be like this:
Value="<%# DataBinder.Eval(Container, "ItemIndex") %>"
try following:
<asp:Repeater ID="myRepeater" runat="server">
<HeaderTemplate>
<table>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><%# Container.ItemIndex %></td>
<!-- or maybe -->
<td><%# Container.ItemIndex + 1 %></td>
<td><%# DataBinder.Eval(Container, "DataItem.Name") %></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
