Answer 1

This Should be your code:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{ 
   if (e.Row.RowType == DataControlRowType.DataRow)
   {
        //Add onclick attribute to select row.
        e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(YourFunction, "Select$" + e.Row.RowIndex.ToString()));
   }
}

Answer 2

e.Row.Attributes.Add("onclick", Myfunction);

需要一个名为 Myfunction 的 javascript 函数，但您的“Myfunction”似乎是一个 C# 方法。

protected void rdb_select_CheckedChanged(object sender, EventArgs e)
        {
            RadioButton selectButton = (RadioButton)sender;
            GridViewRow row = (GridViewRow)selectButton.Parent.Parent;
            int a = row.RowIndex;
            foreach (GridViewRow rw in GridView1.Rows)
            {
                if (selectButton.Checked)
                {
                    if (rw.RowIndex != a)
                    {
                        RadioButton rd = rw.FindControl("rdb_select") as RadioButton;
                        rd.Checked = false;
                    }
                }
            }

        }
