FormView - FindControl
 

Hi
I'm having trouble trying to use FindControl with a FormView, but can't seem
to find what I'm doing wrong....

I have a TextBox in my ItemTemplate, and I want to assign a value to it, in
code...

I'm trying:

((TextBox)FormView1.FindControl("TextBox1")).Text = "Sample value";



The error reported is 'Object reference not set to an instance of an
object.'



Any ideas?



Thanks

Re: FormView - FindControl
 

I've tried it in a few places, prerender, load, databinding etc.

No joy anywhere.

Has anyone actually managed to do this in C#??

Thanks

Re: FormView - FindControl
 

This may help.

protected override void OnInit(EventArgs e)
{
FormView1.ItemCreated += new
EventHandler(FormView1_ItemCreated);
base.OnInit(e);
}

void FormView1_ItemCreated(object sender, EventArgs e)
{
TextBox t = (TextBox)FormView1.Row.FindControl("TextBox1");
t.Text = "foo";
}

Hi,

I'm having the same problem. Could you post the solution here?

Thanks
Chris

And then answer is...

FormView1.Row.FindControl("XXX");

For those of you who are wondering. Or simply if you find an answer post it, don't hide it

I'm having the same problem but usin VB, would anyone have a solution to this in VB? I've never done anything in C# so I don't know how to even start converting it.

Much appreciated
John.
