Getting value of a asp:textbox from grid which is inside repeater
 

Hi,
I have a texbox which is a template column of a grid and the grid is inside the repeater.
If the textbox is directly inside the repeater,then I can make use of the following code.
foreach (RepeaterItem item in Repeater1.Items)
{
TextBox FirstName = (TextBox)item.FindControl("txtFirstName");
Response.Write(FirstName.Text);
}

But I have a grid textbox column and the grid is inside the repeater..So can anyone please help me how to access the textbox.

Thanks
