I tried searching,  bad search-fu,  no helpful tips.

In the radribbonbar control,   is it possible to add a background image with a logo? 
If you have three / four buttons,   then all the space to the right is empty,   which would be great to show of an logo. 

I tried

 

RadRibbonBar   = radMain.BackgroundImage ,   but that didn't work.

Or do I need to turn off Aero?  or?

hi telerik, 
thanks for your help in advance.

the groupbox is bigger and bigger when i set autosize =true.

steps.
 1. drag a radgroupbox into form
 2. drag 3 radpanels into radgroupbox
 3. set the 3 radpanels' dock = dockstyle.top
 4. set radgroupbox. autosize = true
 5. drag a radbutton into form and out of radgroupbox
 6. add click eventhandler to radbotton with below code
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    RadPanel2.Visible = Not RadPanel2.Visible
End Sub
 7.  run app,  click the button continuously,  you can find the width of groupbox is bigger and bigger.

what is wrong and how to avoid ?

Hi

I'm with the trial version of Telerik for Winforms and I'd like to design the following layout:

I want to have a simple combobox at the left of the screen with some predefined options. At the right of the screen, I'll have a group of controls composed by a label, a textbox and a button. I want to have multiple groups but only one will be available to the user when he choose an option from the combobox.

I'm trying to use the LayoutControl, but I have a problem: I'm not able to have 2 or more controls under the same container (my idea is to make visible/not visible the containers to show the correct one). I tried to put a panel on the layout and, later, to create the controls inside it... but the controls are assigned automatically to a new layout item instead the panel I created.

 

How can I do this?

 

Thank's in advance

Is there a way to set the selection color for the RadSpinEditor like you can with a RadTextBoxControl? Or can I change the TextBox element into a TextBoxControl element and set it that way?

Thanks.

I need to find the selected range of cells in a radPivotGridView. 

After I load the radPivotGrid with appropriate DataSources' binding, I need to find when the user has made a selection(i.e. once he releases the left mouse button) on the data displayed under it. I tried to use the MouseCapture event but was unable to access the selected info. in any way.

Kindly help.

Dear support,

i my application in use two classes who implements  INotifyPropertyChanged to reflect the changes on them automaticly in gridview.

These is working quit nice, when using the gui thread.

my application is listening to multiple comports and starts adding new entry's from another thread to this classes.

INotifyPropertyChanged of courses raises an update for the gridview, so that the grid raises an exception because of the wrong thread

where must in place the invoke to make this call thread safe. in the form itself or on the gridview.

Thank you

Hi,

I have RadPageView with a lot of items, which are organized by categories.

 

I'd like that when I click on a category title (PageViewItemType.GroupHeaderItem?) I display the pages which are related to this GroupHeaderItem.

 

Eg.

Organisation (GroupHeaderItem)

 - Page1

 - Page 2

 

Administration (GroupHeaderItem)

 - Admin 1

 - Admin 2

 

I don't see how to accomplish that with RadPageView. 

I chose RadPageView over RadTreeView because the management of the forms that are shown are managed perfectly with RadPageView.

 

Thank you for your help.
