Getting text from databound label

Pharlymal · Apr 28, 2012

I am binding the result set of a database query to the Repeater control, using the <template> to lay out a <table> as follows: //================================================== === // Renders a table looking like: // // <checkbox here> 1 Bugs // <checkbox here> 2 Peter // <checkbox here> 3 Roger // ...etc... //================================================== === <asp:repeater id="repeaterRabbit" runat="Server"> <template name="HeaderTemplate"><table></template> <template name="ItemTemplate"> <tr> <td> <asp:checkbox id="Select" runat="Server"/> <asp:label id="RabbitId" runat="Server"><%# ((DataRowView)Container.DataItem)["RabbitId"].ToString() %></asp:label> <%# ((DataRowView)Container.DataItem)["RabbitName"].ToString() %> </td> </tr> </template> <template name="FooterTemplate"></table></template> </asp:repeater> //================================================== ======== // Now put a linkbutton so the user can shoot some rabbits //================================================== ======== <asp:linkbutton onClick="ShootRabbit_Click" runat="Server">Shoot Selected</asp:linkbutton> //================================================== ========= // Now in ShootRabbit_Click() we find out which Rabbits were // selected to be shot. //================================================== ========= protected void ShootRabbit_Click(Object Src, EventArgs E ) { for( int i = 0; i < repeaterRabbit.Items.Count; i++ ) { if( ((CheckBox)(repeaterRabbit.Items.FindControl("Select"))).Checked ) { Response.Write("TestText"); Response.Write(((Label)(repeaterWebSite.Items.FindControl("RabbitId"))).Text ); } } } When I click the linkbutton and invoke ShootRabbit_Click() the only thing that is written to the page is "TestText", no RabbitId. I am not getting an error, so ASP.NET seems to be able to find the <asp:label> control, but there doesn't seem to be anything in the Text property. It works if I just hard code in a value into the label and don't use databinding. So how do I get at the text of the databound label? TIA Aaron It doesn't look like yo uare telling it to say anything. First of all, take the response.write out. You don;t need that. Then try repeaterWebSite.Items.FindControl("RabbitId").Text = "Say Something" See what I mean?First, there was an typo in the code clip I posted. The "repeaterWebSite" in the last line was junk I accidently left in, instead it should read: Response.Write(((Label)(repeaterRabbit.Items.FindControl("RabbitId"))).Text ); Next, thanks for the reply Rob. The Response.Write was just for test purposes, intended to display the content of the asp:label's Text property - which was what I was trying to get at. And since it wasn't rendering anything I had I feeling I there wasn't anything in the Text property. In fact, the reason that the Response.Write wasn't rendering anything was becuase the asp:label's Text property was empty. In the line: <asp:label id="RabbitId" runat="Server"><%# ((DataRowView)Container.DataItem)["RabbitId"].ToString() %></asp:label> the databinding was not putting anything in the Text property as I originally thought it would. Instead, this line is creating a databound literal control as a child control of the asp:label. The following line actually does the trick: <asp:label id="RabbitId" Text='<%# ((DataRowView)Container.DataItem)["RabbitId"].ToString() %>' runat=Server/> Here the DataItem is acctually assigned to the asp:label's Text property - and the code clip works. (Note the single quotes as well). Thanks to Nikhil Kothari at Microsoft for the help on this. Aaron
