Hi Abdulrahman Nabil,

Thank you for your interest in RadControls for WinForms.

The XP CollapsiblePanel control that you have found in our Integration section of the Examples application is only an example of the possibilities that our Telerik Presentation Framework provides. However, this is not an official RadControl that you will find in our toolbox. As you can read in the Telerik Presentation Framework articles, however, this framework gives you the ability to nest RadElements in an endless hierarchy. That said, you can easily add a button to show the status of the CollapsiblePane using the following code snippet:

buttonElement = new RadButtonElement();
buttonElement.Text = ">>";
buttonElement.MaxSize = new Size(25, 25);
buttonElement.Margin = new Padding(110, 0, 0, 0);
captionFillPrimitive.Children.Add(buttonElement);

RadControlsSpy will be of great use here, since it will display the hierarchy of elements that builds the CollapsiblePane and you will be able to nest the RadButtonElement at the appropriate place. Please find the full approach demonstrated in the sample project attached.

You can also refer to our RadPanelBar control which is an official part of our suite and provides collapsing and expanding behavior. In addition, in Q2 2010 we plan to introduce a new control - RadTabView.

Hi Nikolay ,
thanks so much for replaying me ,thats fantastic
but i stucked out with 3 problems i tried to sortthem out :
1-I'm trying to add a RadtreeView but the CollapsablePane dosn't show that at all , why i can't host Rad controles inside this nice control ,as it allow only RadbuttonElemtns to be hostedinside ?
2-Why when I press the new created button into the header  the control it self dose not repspond to himself by allowing it to collapse or expand or reverse its state?
3-A bug i found with the Control which its dose not collapse to itself closly when I fill the CollapsablePane.item collection with  9 RadbuttonElemnts or more .

,Could you help please this?
that control is critical to me application framwork interface.

Hi Abdulrahman Nabil,

Please accept my apologies for the delayed response.

As I mentioned, the CollapsiblePane control contained in our Examples is just a demonstration of the Telerik Presentation Framework capabilities. However, this CollapsiblePane control is not a fully featured control and should not be used for generic purposes.

The control that you need is RadPanelBar. I am attaching a sample project which demonstrates how you can put 9 RadButtonElements and a RadTreeView control. This project addressed questions 1 and 3.

As to question 2, the RadButtonElement that is placed in the header processes the Click event and this prevents the pane from expanding/collapsing. You should set the button's ShouldHandleMouseInput property to false and the Click event will be processed by the header:

buttonElement = new RadButtonElement();
buttonElement.ShouldHandleMouseInput = false;
buttonElement.Text = ">>";
buttonElement.MaxSize = new Size(25, 25);
buttonElement.Margin = new Padding(110, 0, 0, 0);
captionFillPrimitive.Children.Add(buttonElement);

I hope that the RadPanelBar project will help you in your development process.

Sincerely yours,
Nikolay

Dear Nikolay ,
Good day ,thanks alot for such support ,I've extracted and build your solution but it tell me that :
Error 1 'Telerik.WinControls.UI.RadPanelBarGroupElement' does not contain a definition for 'ContentPanelSize' and no extension method 'ContentPanelSize' accepting a first argument of type 'Telerik.WinControls.UI.RadPanelBarGroupElement' could be found (are you missing a using directive or an assembly reference?) D:\193256_radpanelbarcollapsiblecs\RadPanelBarCollapsibleCS\RadPanelBarCollapsibleCS\Form1.cs 54 43 RadPanelBarCollapsibleCS

how i could fix that ?

Thanks Telerik team

Hi Abdulrahman Nabil,

ContentPanelSize is a relatively new property and you need to update to the latest version in order to use it.

All the best,
