The same link Button control displays twice after clicking the link button placed into Grid's command Item Template.

[Sarang]

I have placed a link button into commandItemTemplate of Grid so that i can add rows to end of grid on server side. But I am observing that whenever there is a postback after clicking link button, the same link button displyed next to the existing Link button.
Clicking the newly created link button does not fired the server side event.
The thing that i have done with grid is that all the rows of grid are in ediable form.


Thanks and Regards

Hello,

I have tried the same but no avail. I am using the version 2011, 2, 915, 35. Here is the sample code.
ASPX:

<CommandItemTemplate>
   <asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton>
</CommandItemTemplate>

Thanks,
Princy.
