AJAX CascadingDropDown - Method Error 500

I downlaoded the sample code accompanying the "Cascading Drop Down Control to Access a Database" AJAX Toolkit video, and added the datasets from the sample code to my application running in VS2008 and AJAX 3.5. I think the sample code is in a prior version of AJAX.

When I ran my project I used to get Method Error 500 and after 2 days of searching the web could not get a solution.

Finally by chance I recreated the datasets fresh in my app using the wizard as shown in the video and the error dissapeared and the cascading drop down worked beautifully.

I hope this post would help anyone who is in the same situation I was.

The script 'Timer.js' referenced multiple times

April 30, 2013, 7:01 pm
$

My company's website uses the AjaxControlToolkit in a few different areas. I was assigned a project that required using an updated version of the toolkit. (the previous version's textbox Calendar extender didn't have the "StartDate" and "EndDate" properties. yeah, it was old.)

So, I upgraded to the latest and greatest by adding the NuGet package, and deleted the old DLL. 

A few (legacy) pages were using the toolkit in UpdatePanels. I have changed the ScriptManagers on those pages to the ToolkitScriptManager. 

The Problem:

The pages with UpdatePanels (UpdateMode="always" ChildrenAsTriggers="true") have an asp:Timer in them. When the page loads, everything is fine. Then, after a seemingly random number of async postbacks (usually the first, and always less than 3), they throw the following JavaScript error:

Uncaught Sys.InvalidOperationException: Sys.InvalidOperationException: The script 'Timer.js' has been referenced multiple times. If referencing Microsoft AJAX scripts explicitly, set the MicrosoftAjaxMode property of the ScriptManager to Explicit.

I haven't been able to reproduce the error in my local version, so far it only happens on our development servers. Unfortunately, the person who wrote the system doesn't work here anymore, and no one has had to touch it until now (lucky me), so I've just been trying things for the last few days...

I've tried moving the timer outside the update panel and setting it as an asyncpostback trigger on the update panel, but that causes other strangeness on the page. I've replaced ScriptManager with ToolkitScriptManager. I've set CombineScripts to false. I've removed calls to ScriptManager and ClientScript, and replaced them with ToolkitScriptManager. None of this has helped.

Any helpful thoughts are greatly appreciated.

Thanks.

PARTIAL POSTBACK

I am a newbie and uptill now i have learned a lot from google however i've now stuck. I've constructed a dropdown list which includes three different selected items which display / hides the textboxes by selecting one of them. When the 'Branch Name' is selected, Textbox5 and 6 must be dissapeared with a partial postback. The code attached yet dissapears Textbox5 only, which doesn't fulfill my need.

When I tried to write the below mentioned lines in my code after the Last line. , it throws an error for closing the tag. I made another update panel 2 but i recieved an error i.e ""An extender can't be in a various UpdatePanel than the control it extends" . Will appreciate your help. Actual Code can be seen below.

</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTriggerControlID="DropDownList2"EventName="SelectedIndexChanged"/>

AutoCompleteExtender in ascx doesn't works..

I've this set:

AutoCompleteExtender (4.1.4.0) in update panel in user control (ascx) and webservice under his ascx.vb and doesn't works.

So I've tested the same markup and webservice method in a simple aspx page and works, so I've some doubt:

- AutoCompleteExtender works in ascx file with webservice function under his code?

- AutoCompleteExtender works in an update panel?

I've always problem to create webservice method using wizard on the control, it return always: Cannot create page method GetCompletionList because no CodeBehind or CodeFile was found! - but I've CodeBehind file..sure!

Thanks!

Cannot get result from AJAX

I have a file called "index.aspx" and part of the code is as follows:

var ServerTime = {
	        get: function(){
		        var ServerTime = "nothing here";
                $.ajax({
                  type: "POST",
                  url: "Index.aspx.cs/getServerTime",
                  data: "{}",
                  contentType: "application/json; charset=utf-8",
                  dataType: "json",
                  success: function(msg) {
                    ServerTime = msg.d;
                  }
                });
		        return ServerTime;
	        }
        }

 

The above code will call the method "getServerTime" in my "Index.aspx.cs" file.

        [System.Web.Services.WebMethod]
        public static string getServerTime(string DateTimeFormat)
        {
            if (DateTimeFormat == null)
            {
                DateTimeFormat = "HHmm";
            }


            String message = "nothing";

            try
            {

                message = DateTime.Now.ToString(DateTimeFormat);


            }
            catch (Exception err)
            {
                message = "Exception found: " + err;
            }


            return message;
        }

The strange things is that when I called the following code:

onsole.log(" Time Server: " + ServerTime.get());

I get the following result, which is not what I expected

Time Server: nothing here

Is there something wrong with my code?

What's Sys.WebForms.PageRequestManager？

Hi everyone,

I meet a question——At my server-side codes, I put a button and a textbox inside the UpdatePanel.

And at the beginning, I wrote the codes like this following in jQuery to assign values:

<head runat="server"><title>Test</title><script src="Scripts/jquery-2.0.0.js"></script><script>
        $(function ()
        {
            $('#<%=TextBox1.ClientID%>').val("I'm Bill Gates!");
        });</script></head>

It works when first running, but when I click the button inside the update panel, it doesn't work anymore!
After searching for the web, I know to use Sys.WebForms.PageRequestManager:
But my question:

1) Why use this?
2) What's that? Is that devoted for UpdatePanel or anything related to AJAX refreshing(even if I'm not using UpdatePanel but I just customized a page that will submit the data contents asychronizedly……), will it work properly?

Many thanks for good explaination!

UpdatePanelAnimationExtender ScriptAction Running on Postback

May 2, 2013, 5:10 pm
$

I have an UpdatePanel which includes some buttons which trigger callbacks and others that trigger postbacks.  The buttons that trigger postbacks are added to the <Triggers> collection. 

<asp:UpdatePanel runat="server" ID="upUpdatePanel"><Triggers><asp:PostBackTrigger ControlID="butStage4Save" /><asp:PostBackTrigger ControlID="butLoadMap" /></Triggers><ContentTemplate>
     ....

I also have an UpdatePanelAnimationExtender which executes a JavaScript function via ScriptAction:

<%--This is what causes the 'updating' animination to run when the specified Update Panel is updating or has updated
The javascript functions that are called are at the top of this page--%><act:UpdatePanelAnimationExtender ID="upae" BehaviorID="animation" runat="server" TargetControlID="upUpdatePanel"><Animations><OnUpdating><Parallel duration="0"><ScriptAction Script="onUpdating();" />  <FadeOut minimumOpacity=".5" /></Parallel></OnUpdating><OnUpdated><Parallel duration="0"><FadeIn minimumOpacity=".5" /><ScriptAction Script="onUpdated();" /> </Parallel> </OnUpdated></Animations></act:UpdatePanelAnimationExtender>

The onUpdating() function runs an animation.  The animation works great during an AJAX request, but my problem is that it also runs when issue a Postback via the Buttons in my <Triggers> collection.  I don't want the user to see the animation during a Postback.

Is there any way to only call the ScriptAction function during a callback, but not a postback?  Or to check some variable in the onUpdating() function to ignore the postbacks?

Thanks.
