How do you add an event handler to a control in a row within a GridView?

I have radiobuttons inside EditItemTemplate tags. I want to add a the event below to each radiobutton. I want the RadioButton to control the Panel within the same row.

protected void uxAddRadioButtonList_SelectedIndexChanged(object sender, EventArgs e)
    {
        uxPanel.Visible = Convert.ToBoolean(uxAddRadioButtonList.SelectedValue);
    }

set the SelectedIndexChange property of the RadioButtonList to "uxAddRadioButtonList_SelectedIndexChanged"

David Robitaille

sorry, the name of the property is
onSelectedIndexChange
(i forgot the "on")

Will the RadioButtonList pair up with the Panel in each row the GridView Control creates?

Got an error:

Compiler Error Message: CS0103: The name 'uxAddRadioButtonList' does not exist in the current context

Any ideas?

Here is more of the code....

        uxPanel.Visible = Convert.ToBoolean(uxAddRadioButtonList.SelectedValue);

is this the right direction...

this compiles, but i think this is having trouble identifying the uxPanel I want to change. The sender object is the RadioButtonList, correct?

How do I find the uxPanel control within the row?

What control do I use to use FindControl within that row?

    protected void uxAddRadioButtonList_SelectedIndexChanged(object sender, EventArgs e)
    {
        RadioButtonList r = (RadioButtonList)sender;
        uxPanel.Visible = Convert.ToBoolean(r.SelectedValue);
    }

ok, you are in the right direction.
you could try r.parent.fincontrol("uxPanel")

ASKER

that worked..thank you

Why does r.Parent.FindControl("uxPanel") work?

How is r considered the Parent in this situation?

Thanks again...

David Robitaille

No, r.parent is the parent of the object "r" so since the RadioButtonList and the panel are "beside" they are in the same "container". So you could access that container by calling the parent property of a control.
Glad I could help.
