Hi.

We are evaluating the latest version of the RadControls for ASP.NET and have come across a problem. I have two separate projects that both contain custom server controls. One project is the main website with it's own server controls and the other project is another set of server controls that would need to be reusable in other projects. Project 1 has a server control with a RadMenu in it placed on the aspx page. Project 2 has a server control with a RadTreeView in it. When I include the server control from project 2 with the RadTreeView on the same page as the RadMenu, I get the following JavaScript errors:

Error: Sys.InvalidOperationException: Type Telerik.Web.UI.Orientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

Error: Sys.InvalidOperationException: Type Telerik.Web.UI.AttributeCollection has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

Both projects import Telerik.Web.UI.

The conclusion I'm coming to is that the scripts are getting registered twice when I bring in the control from Project 2 because it is also referencing the Telerik dll.

I am currently using a ToolKitScriptManager as I tried to implement a RadScriptManager, but it throws an "Object not set" error.

Have you heard of this problem? Is there any way to make it work with using an external server control that also references the Telerik dll? Is there a way to check if Telerik.Web.UI is already imported so it doesn't import it a second time?

Just a note that it works fine if the RadTreeView server control is a part of project 1 also and placed on the page, but the second I add the external control from project 2, it throws those JavaScript errors.

Thanks for any assistance.

How can I clear the AJAX cache of the ToolTip content?  I'm using the ToolTipManager to show history of a record.  However the information won't refresh I think due to the AJAX caching.  How do I force it to refresh?

Thanks.

I'm trying to add a CssClass to a row in my grid. I use an OnItemDataBound method to do this, with the following code:

I wanted to know if there is a way to get other fields populated in outlook such as the location and description.  thanks.

I created a web part feature  that allows a usercontrol to be used in a web part (Not SmartPart). I used several of your code examples and they all work great...in Firefox... I cannot get the rotations to happen in IE. Just blank content.
Additionally, the only way to make a change to the xml and have it reflect is to change the name of the xml file. Otherwise no amount of cache cleaning, or IIS reseting will display the updated xml.
Any ideas?

I am working on an application that uses the splitter and the controls in the main content pane are displaying oddly in all versions of IE. They are not spanning the width and height of the pane and are not aligning correctly. I also have some pages that will not display at all and some that will run in compatibility mode in ie8. Everything shows correctly in firefox though. The app is using a master page and the pane with issues is the ID="rightPane" 


an example of a problem page is: where the content is not spanning the full width and adding extra margin or padding on the top and bottom of the element.

Hi ,
My team is using Telerik Radatbsrip. We are using the liscence version.

we are using  radtabstrip which is having  8 tabs in my "main.aspx" page .All the 8 tabs are binded declaratively with 8 different user controls. The problem is when ever we request for main page it's hitting all the usercontrol's pageload .Even if I click on any tab it's hitting all the user control's pageload. I tried to use dynamic way of adding tabs to tabstrip, it worked for 2 tabs perfectly.But if I try to attach more than 2 it's again hitting all the user control's pageload. Can you please provide any sample or code snippet which will avoid all the pageload hit it will be great . If I click on a particular tab then only that tab's associated user control's pageload should hit. Currently the page is taking 2 minutes to display as it's hitting all the usercontrol's pageload which the client is not happy with.

Can you please help with this issue. It's very urgent...

Thanks

I am adding a RadTreeNode to a RadTooltipManager so that I can display formatted HTML text in the tooltip when someone hovers over the node.  This works fine as long as someone hovers over the node text.  But the RadToolTip doesn't display whenever someone hovers over the node image - instead it just displays a standard tooltip which does not format the HTML. 
Any ideas on how to get the RadToolTip to display formatted HTML when someone hovers over the image would be greatly appreciated.

 

        protected void Button1_Click(object sender, EventArgs e)
        {
           RadTreeNode tn1 = new RadTreeNode();
           tn1.ImageUrl = @"~\images\customer.PNG";
           tn1.Text = "test node";
           string htmlStr = @"<html>test1<br/>test2</html>";
           tn1.ToolTip = htmlStr;
           tn1.AllowDrop = false;
           tn1.Attributes["id"] = Guid.NewGuid().ToString();
           RadToolTipManager1.TargetControls.Add(tn1.Attributes["id"], true);
           RadTreeView1.Nodes.Add(tn1);
        }

 

Thanks,
Scott
