Subject: ASP.Net repeater controls and labeling
No previous message | Next message →

Has anyone found a good way to label repeater controls in ASP.Net?

I have a header row with "label for" tags around the corresponding
column header.
Then below that I've got the data repeating for 15 rows down.

But because of the nature of repeaters, the id for each corresponding
text box dynamically generates at run-time. So you can't correspond the "label for" with the "id" at design time.

Any suggestions on how to best handle this?

Thanks - Lainie

Hi Lainie,

One solution would be to use a literal control to output the label using
the databind event of the repeater control:

<!-html -->
<asp:Repeater ID="rpt" Runat="server>"
<ItemTemplate>
<asp:Literal ID="litFor" Runat="server" />
<asp:TextBox ID="txtBox" Runat="server" />
</ItemTemplate>
</asp:Repeater>

'' vb.net code behind file

Protected WithEvents rpt As Repeater

Private Sub rpt_DataBind(ByVal s As Object, ByVal e As
repeaterItemEventArgs) Handles rpt.ItemDataBound
Dim objItemType As ListItemType = CType(e.Item.ItemType,
ListItemType)

If objItemType = ListItemType.Item Or objItemType ListItemType.AlternatingItem Then
Dim txtBox As TextBox CType(e.Item.FindControl("txtBox"), TextBox)
Dim litFor As Literal CType(e.Item.FindControl("litFor "), Literal)
litFor.Text = "<label for=""" & txtBox.ClientID
& """>LABEL NAME</label>"
End If

End Sub


Note that in a normal ASP.NET page it's very easy to use label for with
a server control when you aren't troubled by binding, by doing the
following for example

<!-html-->
<label for="<%= txtBox.ClientID %>">Search Text</label>
<input type="text" id="txtBox" Runat="server" />

'' vb code behind file
Protected WithEvents txtBox As HtmlInputControl

Hope that helps,
