Toolkit works in ASPX but not in ASCX

Posted By:      Posted Date: September 11, 2010    Points: 0   Category :ASP.Net
Very simple. I used the calendar from the toolkit in a content web form and it worked like a charm. Now i put the exact same code in in ascx web control and now i get the following error in my internetbrowser as popup  'AjaxToolKit Undefined'  So then i put the register ajaxtoolkit tag in the masterpage, contentpage and in the control but still the same error. Anybody knows what's going on?

Code works on aspx but not ascx


Not sure which category to put this question in, so I will put it in here.

Just to give you an idea of the layout of my solution, I have the main project, along with 2 class libraries, BLL and DAL.  (Business Logic Layer and Data Access Layer)

The BLL refers to the DAL and the main project refers to the BLL.

I had a test website and the code worked fine, but the same code will not work on the real project. The only difference is that in the test project, the code was on an aspx code behind, whereas in the real project, it is an ascx code behind (Web User Control )

The code is:

Dim connectionString As String = ConfigurationManager.ConnectionStrings("ASPNETDBConnectionString").ConnectionString
        Dim recordEntry As New UserRecord(connectionString)
        recordEntry.UserName = "TestName"
        recordEntry.BMI = bMI
        recordEntry.BMR = bMR
        recordEntry.FTM = fTM
        recordEntry.TDEE = tDEE
        recordEntry.TodayDate = dateForToday

Dim connectionString As String = ConfigurationManager.ConnectionStrings("ASPNETDBConnectionString").ConnectionString

How to Access Parent Page (.aspx) control (IDs) from its child User Control (.ascx)

I have a parent .aspx page that has a asp:panel control in it, and this parent .aspx is also referencing a user control that I registered in that .aspx. Lets just call it usercontrolA.ascx for this post.The user control has a radiobuttonlist itself.Based on a selection from the radiotbuttonlist in the user control, I want to be able to hide the asp:panel in my .aspx (parent) but unfortunately I cant' get it to work:parentPanel.visible = true;  <<< I trried this in usercontrolA.ascx.csBut the user control doesn't know about the panel in the parent .aspxSo do I need to expose that somehow from the parent so that I can access it from the code behind of the child .ascx?  How?

Nothing works after re-installing Ajax Control Toolkit


Hi all,

Someone in this forum suggested I reinstalled AJAX (to fix another issue) and now none of my apps work! :(
I keep getting the error below:

"Error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll."

I checked my previous ZIP file and noticed the version of AjaxControlToolkit.dll is 3.5.40412.2
So is the new AJAX I've just reinstalled today.

I did some research and people suggested adding ToolkitScriptManager instead. That did not work by the way.
What changed in this "latest" AJAX version? Why am I getting these errors?

Problem with Web Handler - Code works as .aspx, but not .ashx


I'm trying to cover a page that is code-only to a web handler. However, I'm having problems figuring out why the code works when used in the code-behind for the .aspx file but not the .ashx page.

Building a grouping Grid with GridView and ASP.NET AJAX toolkit CollapsiblePanel

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

.Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels
.Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls
The first one is pure design tips one which I used for making good presentation of my demo here. The 2nd post is actually the idea.

Using the WPF Toolkit DataGrid

WPF comes with a large number of built in controls, but from the beginning it has lacked something that many application developers find extremely important - a DataGrid. You can use the ListView to create something approximating a DataGrid

Create an API (aspx vs mvc)


Hi everybody!

I'm not sure if this is the right place to ask this, so, sorry if it's not. I have to create a web application. I can handle that. But, it has a requirement I've never done before. I need to create an API for that application, so other apps can get or set information from/to my webapp.

I've been searching a lot and still don't have a starting point. Seems that MVC is really good to do that, but I'm not familiar with MVC, so I would need a starting point. I was thinking to do it in aspx (Framework 4), but do not know how to do that with aspx either.

Can anyone help me to get started with this?

Thanks in advance

Launch CMD File From ASPX Page


My organization uses a CMD file to install updated files for a major enterprise application. Currently, we send out an email to users with a link to the file and instructions to run it, BUT inevitably users don't update their machines until their in field and try to start the app.


We're now liking the idea of using an ASPX page to prompt the users to run the updates and to capture the fact that the updates have been run. I realize that we can't capture the success or failure of the update. But we'd like to capture the user accessed the page.


Is it possible to embed into the markup for the page a link to the file on the local intranet that the users can click on to run the file?

The user accessing the page would capture that they did just that. We'd deal with wether or not the update was actually installed or if it failed later with them directly.

Custom views on .aspx webpage


Hi again, i have a client that needs me to create a custom view on thier webpage similar to Microsoft Word.

It goes about that, when I click on an image it redirects me to another page and must create a custom view for a certain paragraph on that page. I am not sure how to do this and wonder if anyone knows how.

I am using C# programming language if that helps at all. I Heard that using javascript would work but i dont know javascript yet so is there any alternative?

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.
