Hello Vishnu,

Please comment the following line in the LinkButton1_Click event and you should avoid this error:

    protected void LinkButton1_Click(object sender, EventArgs e)
    {
        // WebDataGrid1.ClearDataSource();
        WebDataGrid1.DataSource = GetDataSource();
        WebDataGrid1.DataBind();
    }

Hi Hristo,

finally find out the issue. while including asp:sitemap control the issue is occurring.

<asp:SiteMapPath ID="SiteMap1" ClientIDMode="AutoID" runat="server" PathSeparatorStyle-CssClass="breadcrumbarrow"
                OnItemCreated="SiteMapPath_ItemCreated" OnItemDataBound="SiteMapPath1_OnItemDataBound"
                PathSeparator="&nbsp;" TabIndex="-1">
            </asp:SiteMapPath>

can you please suggest any solution for the same.

Hello,

I further modified my sample to better match your scenario. The changes that I made are :

1) MasterPage added

2) Code to rebind the grid is executen on button click

3) The grid and the button are placed inside UpdatePanel control

4) Changed references to use 12.1.20121.1005 version

The sample still works fine and I am not able to reproduce the error. Please have a look and let me know if this sample produce the error. If not you can compare it to your app to help you troubleshoot the issue. Otherwise please modify my sample or send me a working isolated sample reproducing the issue.

Hi Hristo,  Thanks for your quick response

}

even this code generate same issue "Multiple controls with the same ID 'it2_0' were found. FindControl requires that controls have unique IDs"

our master page not contain any ig controls.

Hi,

Thank you for your feedback.

Please use the your code to rebind in my sample app and see if it will work. Also modify my sample with anything that you consider related to the issue that occurs. If you manage to reproduce the issue in my sample it will be fine. Or try to isolate your sample and send it for investigation.

You can also specify the exact version of 12.1 that you are using, so I can test my sample app with it.
