How to get element ID's inside repeater control

Question

I am creating a social network site, I cant seem to get the "LinkEmail" in the code behind, I need this to function as I then use it to post to the database.

The LinkEmail is being dynamically generated in the first repeater, I need a way to grab that value.

at the moment I am getting this error in the browser:

Compiler Error Message: CS0103: The name 'LinkEmail' does not exist in the current context

this is aspx code

 <asp:Repeater runat="server" ID="Repeater1">
 <ItemTemplate>

     <div style="border-top: thin none #91ADDD; border-bottom: thin none #91ADDD; padding: 10px;  width: 548px; margin-top: 10px; right: 10px; left: 10px; border-left-width: thin; margin-left: 15px; background-color: #F6F6F6; border-left-color: #91ADDD; border-right-color: #91ADDD;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
                    <br />
                    <div style="width: 58px; height: 40px">
                    <asp:Image ID="Image2" runat="server" Height="59px" ImageAlign="Top" ImageUrl="~/Profile/Image/Default.png" Width="55px" />
                        </div>
                    <div style="width: 307px;  margin-left: 65px; margin-top: -60px">
                        <asp:Label ID="Label6" runat="server" Font-Bold="True" Font-Names="Arial" ForeColor="#3b5998"><%#Eval("YourName") %> </asp:Label>
                    </div>
                    <div id="status" style=" width: 461px; margin-left: 78px; margin-top: 11px;">&nbsp;<asp:Label ID="Label7" runat="server" Font-Italic="False" ForeColor="Black" Font-Size="Medium"><%#Eval("Birthday") %> </asp:Label>

                        <asp:LinkButton ID="LinkEmail" runat="server" OnClick="lbl_Click"><%#Eval("Email") %></asp:LinkButton>
                        <asp:Button ID="Button1" runat="server" Text="Button"  />
                    </div>

                    &nbsp;
                </div>


 </ItemTemplate>

Could you tell me How to get LinkButton ID to my code behind file?

Answer 1

You can find it in ItemCommand event like this:-

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    LinkButton LinkEmail= e.Item.FindControl("LinkEmail") as LinkButton ;
}

You need to associate this event handler with your control like this:-

<asp:Repeater runat="server" ID="Repeater1" OnItemCommand="Repeater1_ItemCommand">

Answer 2

foreach(RepeaterItem item in Repeater1.Items)
{
LinkButton LinkEmail=(LinkButton)item.FindControl("LinkEmail");

//Do here what ever you want

}

using Sender

You get the RepeaterItem by casting the Link button's NamingContainer. Then you can use FindControl to get the reference to your Other Controls.

protected void lbl_Click(object sender,EventArgs e)
{
 LinkButton LinkEmail=(LinkButton)  sender;
 var RepeaterRow=(RepeaterItem)LinkEmail.NamingContainer;

  //find your other control like this
Label Label6=(Label) RepeaterRow.FindControl("controlname")

 //Do here what ever you want
}

Or You can use ItemCommand as Suggested by Rahul singh
