ASP.NET

Hi,

I am using radiobuttonlist and textbox in the gridview. I need to do operations on radiobuttonlist so that it should reflect on textbox . this is to be done after gridview_rowediting event fires i.e when we can see "update" and "cancel" buttons. I tried like this,

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        GridView1.EditIndex = e.NewEditIndex;

        GridViewRow editingRow = GridView1.Rows[e.NewEditIndex];

        RadioButtonList rbl = (RadioButtonList)editingRow.Cells[17].FindControl("rblist11");
        rbl.Visible = true;
        TextBox txtamt = (TextBox)editingRow.Cells[18].FindControl("TextBox3");
        txtamt.Enabled = true;
         
            if (rbl.SelectedItem.Value.Contains("1"))
            {
                txtamt.Enabled = true;
            }
            else if (rbl.SelectedItem.Value == "2")
            {
                txtamt.Enabled = true;
            }
            else if (rbl.SelectedItem.Value == "0")
            {
                txtamt.Enabled = false;
            }
       
    }

Here default selected value is "0" given in source.

My problem here is when I am changing the selecteditem, the corresponding action is not done.

if this action is not done in rowediting event, Please give me the appropriate solution.
