Question

Hey,
Before I start to write my problem, I will excuse for my bad English and I hope you can understand me.

I have in a ASP.NET Webapplication an AJAX Updatepanel. In this Updatepanel is a
Textbox for dynamic search results. When I start to write in the Textbox, the results comes like Google suggest.

Now, the focus must be always on the Textbox (inputn field), now metter whereto the User clicks.

Currently the ASP.NET updatepanel refreshed after a few seconds when the User starts to type.

Thanks for help 🙂

A simple SetFocus f.e. in Page.Load should work:

ScriptManager1.SetFocus (TextBox1.ClientID)

UPDATE: according to this post following works…

Add this script into a script block in your page’s head:

function SetEnd(TB){
    if (TB.createTextRange){
        var FieldRange = TB.createTextRange();
        FieldRange.moveStart('character', TB.value.length);
        FieldRange.collapse();
        FieldRange.select();
    }
}

Then add the onfocus event to your Textbox:

onfocus="SetEnd(this)"

In your codebehind’s Page.Load or TextChanged-Event handler add the standard SetFocus call:

ScriptManager sm = ScriptManager.GetCurrent(this);
sm.SetFocus(myTextBox)
