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

Thank you

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

Visual Studio / App Hanging on GridView

When trying to add a GridViewTextBoxColumn to my gridview control through the property builder my Visual Studio Devenv becomes completely unresponsive. When adding it through code the program completely locks up. No error just CPU usage to 50% steady and nothing else happens. Below is how the column is created and added on my other Dev box and was created by the property builder. I dont actually beleive it is a version problem because if I create a new form add the gridview to it and try to add a column my UI freezes so if it were a version issue then the entire version I have would be broke.

Note...
I have removed and re-installed the controls twice with the same effect both times. Version 8.1.0.0

......
Telerik.WinControls.UI.GridViewTextBoxColumn gridViewTextBoxColumn13 = new Telerik.WinControls.UI.GridViewTextBoxColumn();

gridViewTextBoxColumn13.FieldName = "ProjectName";
gridViewTextBoxColumn13.HeaderText = "Project Name";
gridViewTextBoxColumn13.HeaderTextAlignment = System.Drawing.ContentAlignment.MiddleLeft;
gridViewTextBoxColumn13.IsVisible = false;
gridViewTextBoxColumn13.UniqueName = "ProjectName";
gridViewTextBoxColumn13.Width = 5;

this.radGridFileList.MasterGridViewTemplate.Columns.Add(gridViewTextBoxColumn13);
.........

Context Menu

Getting an odd issue with the radcontextmenu ,

I can create one and add it with the radcontextmenumanager to the controls needed all np.
However it doesn't seem to get the theme it's assigned or any theme for that matter.

So when I right click and the menu appears it appears as most of the controls appear when
they have no theme loaded (gray/white background with those darker gray borders around everytime)

It ends up that the menu looks like stacked gray blocks and ofc while you can click on each item,
due to the theme not applying, when you mouse over each item the highlights don't appear.

I've tried setting to all different themes and no luck. I assume I am missing something simple ?

RadButton Text Antialiasing

I am using the RadButton in my app which has large buttons in order to accomodate touch screens. As a result, my buttons are pretty large and the text in them ends up looking blocky.

I would like to use antialiasing or cleartype to render the text in the button, but am not sure how to do it. Is there some sample code to show how to do this?

Thanks,

David

Design Tool Colors in VS 2008

I have a visual disability that limits my sight to white text on a black background. I can also see other high contrast colors, as long as they are on a dark background. I just recently purchased and started using the RadControls for WinForms. My computer’s Display Properties are set for an appearance and color scheme of “High Contrast Black”. This setting work fine in Visual Studio 2008, all the views and property pages show with high contrast white text on a black background with white grid lines when present – I can see everything just fine. My problem if with the Telerik extensions to Visual Studio where property / design pages open-up with a “Vista” like color theme of a white background and white text – even if the text was black I still could not see it on the bright white background. Is there any way to re-color the Telerik design pages to follow the windows color scheme? Or maybe force them to other colors? My OS is Windows 2003 server.
