Setting Focus with ASP.NET AJAX Control Toolkit

Question

I'm using the AutoComplete control from the ASP.NET AJAX Control Toolkit and I'm experiencing an issue where the AutoComplete does not populate when I set the focus to the assigned textbox.

I've tried setting the focus in the Page_Load, Page_PreRender, and Page_Init events and the focus is set properly but the AutoComplete does not work. If I don't set the focus, everything works fine but I'd like to set it so the users don't have that extra click.

Is there a special place I need to set the focus or something else I need to do to make this work? Thanks.

We had exactly the same problem. What we had to do is write a script at the bottom of the page that quickly blurs then refocuses to the textbox. You can have a look at the (terribly hacky) solution here: http://www.drive.com.au

The textbox id is MainSearchBox_SearchTextBox. Have a look at about line 586 & you can see where I'm wiring up all the events (I'm actually using prototype for this bit.

Basically on the focus event of the textbox I set a global var called textBoxHasFocus to true and on the blur event I set it to false. The on the load event of the page I call this script:

if (textBoxHasFocus) {
    $get("MainSearchBox_SearchTextBox").blur();
    $get("MainSearchBox_SearchTextBox").focus();
}  

This resets the textbox. It's really dodgy, but it's the only solution I could find

this is waste , its simple

this is what you need to do

controlId.focus(); in C# controlID.focus() in VB

place this in page load or button_click section

eg. panel1.focus(); if panel1 has model popup extender attached to it, then we put this code in page load section
