Question

如何在后台给gridview中的模板列中的radiobutton 赋checked值.

Answer 1

首先给模板列里的控件改名字为rdo
protected void radiobutton1_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i <GridView1.Rows.Count ; i++)
{
//找到模板列中的控件 知道ID用FINDCONTROL
//不知道ID用CONTROLS[0];
radiobutton RadBtn= (radiobutton)GridView1.Rows[i].Cell[所在列].FindControl("rdo");
//寻找模板中的rdo控件 如果全部赋值 用循环 否则 GridView.Row[所在行].Cell[所在列]
rdo.Checked =! Rdo.Checked;
}

Answer 2

protected void radiobutton1_CheckedChanged(object sender, EventArgs e)
{
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
radiobutton RadBtn= (radiobutton)GridView1.Rows[i].FindControl("radiobutton ");
if (radiobutton .Checked == true)
{
RadBtn.Checked = true;
}
else
{
RadBtn.Checked = false;
}
}

不知道是不是你想要的代码！希望对你有帮助
