But I don`t Want to set Text with this format : RadioButton1.Text = dt.Rows[0][0]; RadioButton2.Text = dt.Rows[0][1]; . . . RadioButton80 .Text = dt.Rows[0][0]; I want to Use this codes : RadioButton rb; for(int i=1 ; i < 81 ; i++) { rb = (RadioButton)this.FindControl("RadioButton" + i ); rb.Text= dt.Rows[0][i].ToString(); } But there is error with Details : Object reference not set to an instance of an object. why??? please help me to find correct way.

this weeks tips: - make Visual display line numbers: Tools/Options/TextEditor/AllLanguages/General - show exceptions with ToString() to see all information - before you ask a question here, search CodeProject, then Google
