set focus on label using Page.SetFocus 2.0

[columbo2]

Hi All,

Does anyone know how to use Page.SetFocus to set focus to a particular point on a page.
I have an error message that pops and I want the page to focus on it.

If I use Page.SetFocus I can set focus to a textbox but not to an anchor or label.

Can anyone help?

Thanks

In the future please use forum855 and forum216 for questions related to web development.

use the registerstartupscript method to append javascript to the page. the javascript will set the focus to your desired control. google javascript setfocus if you need the js code.

Tip: use myControl.ClientID to construct the js. not MyControl.ID. MyControlID is unique on the server, not the client. MyControl.ClientID will create a unique id on the client which will be required to find the control.

Hi, thanks for your help!

I've tried...

ClientScript.RegisterStartupScript(typeof(Page), "SetFocus", "<script>document.getElementById('" + labErrorText.ClientID + "').focus();</script>");

where labErrorText is the control I want to focus on.
Sadly, it doesn't work. I substituted in a simple alert and that works OK but the focus javascript doesn't work.

Can anyone see where I'm going wrong

thanks
C

focus is meant for input controls. if labErrorText is a Label you can't set the focus (99% s ure). instead you need to use a anchor tag.

Hi,

I put <a id="erroranc" runat="server"> .... </a> on the HTML page and then...

ClientScript.RegisterStartupScript(typeof(Page), "SetFocus", "<script>document.getElementById('" + erroranc.ClientID + "').focus();</script>");

but still no joy?

I've even tried a readonly textbox with no border and 1 width but it doesn't like that either.

Thanks
