Set Focus on PostBack

**Plater** · Jul 27 '07, 04:14 PM

As much as I hate to admit it (:-P) if you run it in firefox with that DOM parser thing on you will see a lot more hidden errors.

Are you remembering to have your body tag's onload function call out to that javascript onload thing

I'm going to ask one more small but vital question.

Are you using any use of Ajax in your html design?
Are you using the AjaxControlTool kit's UpdatePanel?

I just tried with firefox and it works, but not with Internet explorer. I didn't get any javascript error. I don't get it, whats wrong with IE (lol) then.

I'm not using AJAX in this application, this is an old application, it was develop long time before I started working here.

Have you checked out w3c?
Have you seen their focus() method example?

I tried their example in IE and it works fine....
Maybe you might find then answer in w3c.

It doesn't seem to work with a asp button, I got this error:
Compiler Error Message: BC30390: 'ASPNET.Starter Kit.Portal.Prod uctLookUpPage.P rivate Sub SetFocus(Client ID As String)' is not accessible in this context because it is 'Private'.

Could you post the html code for your aspx page?

'07/20/07 This procedure sets focus to specific controls.
Private Sub SetFocus(ByVal ClientID As String)
Dim Script As New System.Text.Str ingBuilder
'Dim ClientID As String = FocusControl.Cl ientID
With Script
.Append("<scrip t language='javas cript'>")
.Append("docume nt.getElementBy Id('")
.Append(ClientI D)
.Append("').foc us();")
.Append("</script>")
End With
RegisterStartup Script("setFocu s", Script.ToString ())
End Sub

Change the SetFocus method to be a public method instead of a private method.

Change the SetFocus method to be a public method instead of a private method.

I set it to public but still gives me an error

You are getting this error because your button has a runat=server.
So since it is an asp button, it is trying to call the server side code called SetFocus (except this function is private and so you get an error). It is not calling the JavaScript function called SetFocus as because it is an asp button and is calling the Server Side code.

In order to call JavaScript using an asp button you'd have to do something like the following in your in your server side code:

BTN_MyButton.At tributes.Add("O nMouseUP", "SetFocus(' " + TXT_myTextBox.C lientID"');")

However, the asp button will cause a PostBack event.
Since this happens your focus will be lost when the page is redisplayed in the browser.

If you were following the example from the w3c site and substituted the <input type="button"> for <asp:Button>, the example will obviously not work for these reasons.
