Hi all,

I have a form with an input radio control in a template field.
When the user selects an option, and press a button
the selection disappears.. I would like the selection to
persist after the button makes the postback,

I tried using the findcontrol but it returns null, and do not know how
to make sure that the radio selected persist after the button
action makes the postback.

Thanks in advance,

Carlos.

推荐答案

在模板字段中的radiobutton控件上启用viewstate吗？

enable viewstate on the radiobutton control in the template field?

谢谢你的回复。但是，我已经将enableviewstate设置为

true，

，问题是在这个片段中，控件变量为空。

即显然它找不到控件：


for（int i = 0; i< GridView2.Rows.Count; i ++）


{


GridViewRow row = GridView11.Rows [i];


HtmlInputRadioButton rb =

（HtmlInputRadioButton） （row.FindControl（" rbMonday"））;


if（rb.Checked == true）


{


Response.Write（" found it .."）;



//第2列是名称栏


}

}


谢谢，


Carlos。

Thanks, for the reply. However, I already have the enableviewstate set to
true,
and the problem is that in this snippet, the control variable comes null.
i.e. apparently it can not find the control:

for (int i = 0; i < GridView2.Rows.Count; i++)

{

GridViewRow row = GridView11.Rows[i];

HtmlInputRadioButton rb =
(HtmlInputRadioButton)(row.FindControl("rbMonday") );

if (rb.Checked == true)

{

Response.Write("found it..");


// Column 2 is the name column

}
}

Thanks,

Carlos.

你有runat =" server"在html单选按钮？


也许你可以粘贴templatefield html。

Carlos写道：

Do you have runat="server" in the html radio button?

Perhaps you could paste the templatefield html.
