Hi Eduardo,

Please elaborate on the problem you have encountered. What is the exact effect of the issue? Have you received any error messages or the controls on your page just do not function as expected?

You mentioned a regular ASP Button in your post. Are the standard controls affected as well by the problem?

Note that when RadCompression is enabled event handlers might not be raised in a default document in IIS 7 or IIS 7.5 Integrated Mode. If this is the problem in your case I would suggest checking the Known issues section of the help article RadCompression as it contains more information on the matter.

Hi Slav!

My example does not show exactly what happened!

The problem is not the button, but when operate or manipulate any control of Telerik!

Example:

  "
  private void ShowRadPageView()
  {
   //Note: Telerik.Web.UI.RadPageView!
   (RadPageView)ResultRadPageView.Selected = true;
   (RadPageView)ResultRadPageView.Visible = true;

  }
  "

Below is the "system.web" of my "Web.config"!

"

I emphasize that in either "classic" as in "integrated" (IIS 7.5), we got this problem!

The problem seems to occur when the Telerik makes ajax calls to manipulate some control.

Please help me! It is for a very special customer!

Hugs!

Hi Eduardo,

I created a test project, based on the information you provided, but I am unable to reproduce your problem. I have attached my sample project to this post so that you can check if the issue occurs on your end. The behavior that I encountered is displayed in the attached screen capture.

Note that I am still guessing as to what the exact problem is and what is the setup of your actual project. Please try reproducing the issue in the attached sample and if you are successful, let me know what changes should be done in order to match your case. A detailed description of your configuration, the steps for reproducing the problem and the effect of the issue will also be useful for determining its cause.

Kind regards,

Dear Slav,

No doubt! The problem is at Telerik! My logs tell you that! As an example, the call of the method below:

            Note: Just when we call this method on line "((RadPageView) ResultRadPageView). Selected = true;", as in other operations with Telerik controls the application does not respond and the screen is not changed!

            "
            private void ShowRadPageView ()
            {
                  / / Note: Telerik.Web.UI.RadPageView!
                  ((RadPageView) ResultRadPageView). Selected = true;
                  ((RadPageView) ResultRadPageView). Visible = true;
            }
            "

Is not there a script (manual) installation to use the Telerik in IIS 7.5?

I need to install Telerik (installer) on my server?

I opened your application and it worked. However, I spend too much time to do implementations in it!

My situation is getting complicated and I'm really running out of time!

Is there any other solution that you can suggest?

Can you send me an application test that control "Telerik.Web.UI.RadPageView"?

I deploy on another Windows 2008 R2 (another server) and got the same problem!

The system behaves as it appears in the picture (attached). When I make a request, it does not respond! He is eternally waiting for an answer! Sometimes, back to the home screen of the system (default.aspx).

Hello Eduardo,

After examining again the provided sample from web.config I noticed that there is no <system.webServer>. Keep in mind that when a web site is running under IIS7, you need to register the HttpHandlers in the <system.webServer> section as the web server searches them in the content of this tag. You can check the help article Registering the HttpHandlers on Windows Vista IIS 7 Integrated mode for more information on configuring the web config in such a scenario.

Also I would suggest updating your version of RadControls to the latest release as the encountered problem could be related to the version you are currently using.

Note that in my previous post I have attached a sample that uses RadPageView and the web config setup that you provided, so you can check if the problem is reproducible there.

Hi Slav,

I did some more tests with your code example ("RadControlsSample") and in your code Telerik works, such as:

"
protected void Button1_Click(object sender, EventArgs e)
{
RadPageView4.Selected = true;
RadPageView4.Visible = true;
}
"

I changed the "web.config" exactly as you guide. Below is the "<system.web>" and "<system.webServer>" (Note: IIS 7.5 is in integrated mode!)

RadControlsSample.zip

Hello Eduardo,

I have modified my test sample, according to your suggestions and the RadComboBox loads its items as expected. Since the difference with your sample code is the data source that you are using to create the combo box items, I would suggest checking if the data is loaded successfully.

Also, as stated in the help article Controls are not updated during the ItemsRequested event, it is not recommended to use the built-in callback machinism of RadComboBox along with Telerik RadAjax, so I would suggest checking if this is the case.

You can find attached the modified sample so that you can verify that the RadComboBox is loading its items with the standard approach on your end.

All the best,
Slav
