GZIP compression

protected void Application_PostReleaseRequestState(object sender, EventArgs e)

{

string contentType = Response.ContentType;

if (contentType == "text/html" || contentType == "text/css" || contentType == "application/x-javascript" || contentType == "application/json")

{

Response.Cache.VaryByHeaders["Accept-Encoding"] = true;

string acceptEncoding = Request.Headers["Accept-Encoding"];

if (acceptEncoding != null)

{

if (acceptEncoding.Contains("gzip"))

{

Response.Filter = new GZipStream(Response.Filter, CompressionMode.Compress);

Response.AppendHeader("Content-Encoding", "gzip");

}

else if (acceptEncoding.Contains("deflate"))

{

Response.Filter = new DeflateStream(Response.Filter, CompressionMode.Compress);

Response.AppendHeader("Content-Encoding", "deflate");

}

I got this code in global.asax, i want gzip enabled, but not on iis level, but after this, radDateTimePicker is broken.
it still "works" but it has no style, pick button is repeated in strange way, and the title of hyperlink is shown instead of image button; Am i doing something wrong?

How to make element in Grid perform a full submit

Hi,

I have placed some extended HyperLink-Elements in my Grid and need them to perform a full page submit. But when I click on the links only the Grid refreshes. What do I need to do to get the expected behavior?
-
The Grid is created programatically and replaces a PlaceHolder element on the page.

ASP.NET controls styling issues in SharePoint 2007

I love the Telerik controls, and have decided to use them in a SharePoint 2007 project.

For the most part, they are working well, and functioning perfectly.

There are some issues however, and I'm wondering if anyone has come across this. I've attached some screenshots. The problem seems to be centered around textboxes.

Thanks for your time

I've included the markup for my textboxes and grid:

Installation error: Could not open Telerik.Web.UI_2011_2_915_Dev.msi or Telerik.Web.UI_2012_1_215_Dev.msi

Hi,

I just downloaded both Telerik.Web.UI_2011_2_915_Dev.msi and Telerik.Web.UI_2012_1_215_Dev.msi. So that I can upgrade my current Telerik.Web.UI current version (2008.2.1001.35). But I can't seem to install either of them. I am getting the Windows Installer error "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."

Other info
- OS: Windows XP SP3
- Just upgraded my ASP.NET project from VS2008 (.NET 3.5) to VS2010 (.NET 4.0)
- The current project is also now a hybrid ASP.NET Web Forms and ASP.NET MVC 3. That's why I need to get the new version because I am getting some weird "microsoft jscript runtime error object doesn't support this property or method" error and hoping that upgrade in the control might fix my problem, which did not exists in VS2008.

Can you please help?

Regards,
Midas

RadAjaxManager with RadWindow doesn't ajax controls in window

I have been battling a problem recently with RadAjaxManager.

I have a RadButton that opens a RadWindow using AJAX (calls a postback that set's VisibleOnPageLoad=true). But any button in the window that was open won't make it's postback through ajax. Instead it makes the request through a normal postback. If I set the RadButton to do a normal postback (not setup an ajaxsetting for it) then the buttons in the RadWindow work.

Any ideas on what I am doing wrong? I have tried searching the form and google to find a solutions and can't find anyone else that is having the same problem.

I have included the parts of code that are related to the problem (i hope)... thanks in advance.

[Solved] Remove the Image Map Editor from everything

Hi,

This should be a relatively quick question to answer.

We want to disable the image map editor from everything within the rad editor.
I've already removed it from the context menu of an image within the rad editor by modifying the Tools of the RadEditors ContextMenus so that only the Properties option shows up.
But I want to ensure that an image map cannot be made anywhere else.

Thanks,
Cameron

Upload button appearing not like a button

Hello,

We've been having an issue where users are seeing the upload button within the Upload Dialog of the Image Manager Dialog appears as text with a dashed border around it. I do not know if the button is disabled or not or even if it is functional as a button.

However it is appearing as not a button.

Any ideas on why this may be happening?

Thanks,
Cameron

PS. We are using the 2011.3.1305.40 version of the controls.
