Question

gridview 怎么获取RadioButton选中行的值？

protected void butpreview_Click1(object sender, EventArgs e)
{
string bugid = "";
foreach (GridViewRow rowview in GridView1.Rows)
{
RadioButton box = (RadioButton)rowview.Cells[0].FindControl("RadioButton1");
if (box.Checked == true)
{
bugid = rowview.Cells[1].Text;

}
}
Session["bugid"] = bugid;
Response.Redirect("preview.aspx");
}
调试过，box的值是空的，那出了问题？或者有没别的方法？谢谢
RadioButton是在第一列啊

Answer 1

bugid = rowview.Cells[1].Text;
里面的“rowview.Cells[1].Text;”：1、要把Cells[1].这一列设为模板列！在ItemTemPlate中拖入一个TextBox！
2、给bugid赋值的时候应该也是写成“ Convert.ToString(((TextBox)rowview.Cells[1].FindControl("TextBox1")).Text);”这种形式！

Answer 2

Cells[0]代表第一列，你确定你的RadioButton放在第一列？
把Cells[0]去掉试试。。

Answer 3

RadioButton box = (RadioButton)rowview.FindControl("RadioButton1");
