[Solved] Customize ContextMenu of TabItem

What is the best way to go about customizing what options appear when you right click on a tab in a docking manager? I know its possible to show/hide the context menu via the TdiContextMenuVisible property. Ultimately what I want to do is remove the ability of users to create their own tab groups. I like the "Close All Tabs Except for this" option and would like for that to remain.

Thanks in advance.

[Solved] radTabStrip DragDrop

I am trying to implment the ability for another control to drag and drop onto tabs in a radTabStrip. I have been able to implment most of it, but am having difficulty determining which tab the user dropped on.

I would have thought I could put the following code in the DragDrop event of the TabStrip, but the GetItemByPoint always returns nothing, even when tabs were dropped on.

    
            Dim tab As Telerik.WinControls.UI.TabItem  
        
            tab = radTabStrip.TabStripElement.GetItemByPoint(New Point(e.X, e.Y))  
        
            If tab IsNot Nothing Then  
        
                MsgBox(tab.Name)  
        
            End If

Any help would be appreciated.

I am using VB.NET in VS2008

Thank you -- controls are still fantastic

DropDownButton Question

is the following possible:

i want to have a DropDownButton, but the drop down menu should only collapse, when the arrow part of the button is pressed.
Pressing the "Image" area of the button, the Click event for the button should be fired.

i have not found any way to find out whether tzhe arrow part has been pressed or not.

Edit: Just to make more clear what i want. Look at the "Paste" button in Word. Wenn cou click on it, it does a simple paste, when you click the arrow part it offers some options.
A Gallery could do it, but unfortunately a Gallery Element can't co-exist with other items in the same chunk. At least not in the version i'm using (the one that MS publishes oin the VC# express site).
It doesn't show me the arrow elements. when being the only element in a chunk it is ok.

Binding to Sub Objects

I'm trying to bind a radgridview to a generic list of objects.

Each object in my generic list contains yet another class object.

For instance, I want the columns in my grid view to be like this:

Row1Column1 = GerericList(0).Property1
Row1Column2 = GerericList(0).Property2

..this works for me... but I haven't found a way to do this...

Row1Column3 = GerericList(0).Property3.SubProperty1
Row1Column4 = GerericList(0).Property3.SubProperty2

Make sense?
Is this possible when I bind a grid view to a generic list?

Cell Validating keep edit in current cell

I am trying to set edit back to cell if no value is entered.
I am using the validating event.
It traps the empty event nicely but when I try to move focus and edit back to the empty cell if refuses and jump to next column in same row.
My code is as follow:

    
            'get column number  
        
                    Dim col As Int32 = Me.RadGridView1.Columns.IndexOf(Me.RadGridView1.CurrentColumn)  
        
                    'test first if valid lognumber  
        
                    If col = 0 Then  
        
                        Dim input As String = (Me.RadGridView1.ActiveEditor.Value.ToString())  
        
                        If input = "" Then  
        
                            MsgBox("empty")  
        
                            e.Cancel = True 
        
                            Me.RadGridView1.Rows(0).IsCurrent = True 
        
                            Me.RadGridView1.Columns(0).IsCurrent = True 
        
                            Me.RadGridView1.BeginEdit()  
        
                        End If  
        
                    End If

RadComboBoxElement with text clipped

I have a RadToolstrip that contains multiple RadComboBoxElements.

I've resized the comboboxelements to larger (than default) width to fully display the text within it. Although the combobox is resized to the expected width, the embedded textbox is not resized. Thus the text is clipped.

I noticed that someone else on the forums (in 2007) noticed the same behaviour and the advice was to change the width of both minSize and maxSize. I've done this but didn't see any change to the behaviour.

I'm using the 2008 Q3 version.

To reproduce
1.create a simple winforms project
2. add a radtoolstrip (i docked it to top)
3. add a radcomboboxelement and change minsize, maxsize widths to 150.
4. run program

You'll see the default name radComboBoxElement1 is clipped

Any suggestions?

Unicode font not working on Document Pane

I'm using Arial Unicode as the font for the Docking Manager & Document Pane so that I can display Chinese characters. However, the font does not seem to change and the Chinese characters I display, display as squares. I can use any other Telerik control e.g. button or label, set the font to Arial Unicode and the Chinese characters display correctly.

Any ideas?

Thanks
Ralph
