TextBox.Focus not working in FormView

[J055]

Hi

The client script does not get created when calling the Focus method on the
TextBox. No errors occur. What am I doing wrong please?

protected void fv_Load(object sender, EventArgs e)
{
FormView fv = (FormView)sender;
TextBox tbFirstName = (TextBox)fv.FindControl("tbFirstName");
tbFirstName.Focus();
}

Thanks
Andrew

What happens if you rem out the first two lines within the method...?

Alternatively, what happens if you put the third line of the method in
Page_Load()...?

Hi Andrew,

As for setting control focus inside a FormView control, I suggest you the
"PreRender" event, because this is the last event in control's server-side
lifecycle that can use to change control state. Also, in those earlier
event(such as Load), the FormView's content may haven't been fully
configured so our changes on them may bave been overwritten by some other
internal code. Also for "focus" setting, it is also a global setting on
page, maybe some other controls on page will acquire the focus also.
Therefore, I think you can put the code into FormView.PreRender event
handler as below:

================
protected void FormView1_PreRender(object sender, EventArgs e)
{
if (FormView1.CurrentMode == FormViewMode.Insert)
{
TextBox txt = FormView1.FindControl("nameTextBox") as TextBox;

if (txt != null)
{

Page.SetFocus(txt);
}
}
}

=======================

Hope this helps.

Sincerely,
