在ASP.NET中的GridView中使用RadioButton的问题(Problem with usage of RadioButton in GridView in ASP.NET)

    <asp:TemplateField HeaderText="Select One">

    <ItemTemplate>

    <input name="MyRadioButton" type="radio" />

    </ItemTemplate>

    </asp:TemplateField> 
 
 aspx.cs 
 
protected void Button1_Click(object sender, EventArgs e)
{
    foreach (GridViewRow di in GridView1.Rows)
    {
        RadioButton rad = (RadioButton)di.FindControl("MyRadioButton");
        //Giving Error:Object reference not set to an instance of an object.
        if (rad.Checked&&rad!=null)
        {
            s = di.Cells[1].Text;
        }

    }

    Response.Redirect("applicants.aspx?form=" +s);

}

{
    foreach (GridViewRow di in GridView1.Rows)
    {
        RadioButton rad = (RadioButton)di.FindControl("MyRadioButton");
        //Giving Error:Object reference not set to an instance of an object.
        if (rad.Checked&&rad!=null)
        {
            s = di.Cells[1].Text;
        }

    }
