Question

I am using the following code to call a javascript function but the OnClientClick expression is never evaluated.

<asp:Button ID="btn1" UseSubmitBehavior="false" 
OnClientClick='moveComment(txtComment_<%# Eval("Container.DataItemIndex") %>)'
runat="server" Text="add comment"/>

Answer 1

Here is the answer:

<asp:Button ID="btn1" UseSubmitBehavior="false" OnClientClick='<%#    
GetId(Container.DataItemIndex.ToString()) %>' runat="server" Text="add comment"/>

And GetId method on the server side:

protected string GetId(string index)
{
return “moveComment(‘txtComment_”+ index +”‘)”;
}
