RegisterStartUpScript() Not Working After Adding AJAX UpdatePanel (VB.Net)

RegisterStartUpScript() Not Working After Adding AJAX UpdatePanel (VB.Net)

RegisterStartUpScript() Not Working After Adding AJAX UpdatePanel (VB.Net)


I had a working web site, but wanted to add a ProgressBar to it. After much trial-and-error, I finally decided to try using the Ajax UpdatePanel on it to handle the ProgressBar.

Previously the ScriptManager.RegisterStartupScript() was working just fine.
Once I added the Ajax Updatepanel, it quit working.

I see a variety of other postings on other websites about this problem, but there does not seem to be a definitive solution.
Some people tried one thing and it worked, but did not work for others, etc.
I tried a number of "throw it on the wall to see if it sticks" approaches, but they too did not work.

What used to work and successfully launched 'startup' javascript:
ScriptManager.RegisterStartupScript(Me.Page, Page.GetType, "MyStartUpJavaScript", "startUpScript()", True)

Any suggestions/advice would be greatly appreciated.


RE: RegisterStartUpScript() Not Working After Adding AJAX UpdatePanel (VB.Net)

I forgot to add that I want the StartUp javascript to execute when the Whole Page executes.

I don't see that this StartUp javascript should need to execute when the UpdatePanel refreshes (every one second after being 'Triggered') - since that only displays the ProgressBar and not the other form objects which the startup javascript 'manipulates'.

Since I don't know if that may or may not be pertinent to the issue, I thought that I'd throw it in.

I MAY have found the answer even though I am not sure why.

By changing the syntax to:
ScriptManager.RegisterClientScriptBlock(TryCast(sender, Control), Me.GetType(), Guid.NewGuid().ToString(), "startUpScript()", True)

It is now launching the intended javascript - startUpScript()

I now have another issue related to that, but I will post it in a javascript area of the forum.


RE: RegisterStartUpScript() Not Working After Adding AJAX UpdatePanel (VB.Net)

Please forget what I said above about a 'new' problem.

Actually my primary problem stated here, while seeming to be resolved, was really not.

So let me restate my problem in a hopefully more clear manner.

I have an ASP.Net webpage that used to work just fine.
That code had in it a working javascript StartUpScript that I launched with a:

CODE --> VB.Net

ScriptManager.RegisterStartupScript(Me.Page, Page.GetType(), Guid.NewGuid().ToString(), "startUpScript()", True) 

But I wanted to add a ProgressBar to the back-end table updates that are launched with a Button Click (not a SUBMIT button).
After trying a number of things, I finally decided to try AJAX and their approach to a ProgressBar using an UpdatePanel.

I followed a rather clearly presented approach and put that code in place - and from a methodology approach it looks as though it might really work.

But when I first launched the code, I saw that my javascript StartUpScript was not executing - Firebug was not breaking at my intended javascript Function

It appeared that AJAX was creating its own javascript and that it was running instead of mine.

Point of reference, when I first launch the page the AJAX javascript seems to run and I never see my javascript code run.
However if I do a manual Page Refresh through the browser control, my javascript StartUpScript seems to be launched, but it cannot 'see' any of the form objects that I need.

From web readings that I have done ALL DAY, I am guessing that one of the javascript code launches is for the AJAX UpdatePanel load and the other javascript code launch is for the over-all form. But I cannot tell which is which and what code it SHOULD be running at launch.

What more information can I offer to help you assist me in finding the answer?

As before, any advice/suggestions you might have would be greatly appreciated.
