Find Control by ID

Remarks:

FindControl is not recursive, it only searches through immediate children of the control
There is an overload FindControl(String, int) which is not indented for public usage
If nothing is found, FindControl returns null, so this is often a good idea to verify result for being not null

TextBox txt = (TextBox)FindControl(yourtxt_Id);

If the Control has rows.

TextBox tb = GridView1.Rows[i].FindControl("TextBox1") as TextBox;

Or if it has items.

TextBox tb = Repeater1.Items[i].FindControl("TextBox1") as TextBox;
