Failed to create component "RadRibbonBar"

I just downloaded the latest trial copy of the Telerik components and tried to create a basic UI. When I dropped a "RadRibbonButton" onto my form I got the following error in Visual Studio (2008, 35SP1)

Failed to create component "RadRibbonButton". The error message follows:
System.NullReferenceException: Object not set... at:
Telerik.WinControls.UI.RadRibbonBar.get_QuickAccessToolBarItems()'

Any ideas how to resolve this?

Persist group expansion after databind

Hello,

It seems that my grouping is collapsed when I rebind bind my grid to a datasource.

Bind grid
Drag column header to grouping panel
Expand second group
Rebind grid
All groups are colapsed once again

Is there a way to determine which groups were expaned before the bind and then iterate through the new groups and if it finds a match, expand it?

Thank you, Tyler

ConvertToDataSource and ConvertToScheduler

I am trying to implement my own DataSource to the Win scheduler.
I have read the "Using a Data Provider" topic in the documentation, where the steps into making this happen are explained.

However, there is one part that is missing (or that I am missing) in the code listed there.

What should the code in ConvertIdToDataSource and ConvertIdToScheduler method should contain?
All we see is the following line and the documentation is not providing much information regarding those two properties except that it should "convert given value object to scheduler object".

idMapping.ConvertToDataSource = new ConvertCallback(this.ConvertIdToDataSource);
idMapping.ConvertToScheduler = new ConvertCallback(this.ConvertIdToScheduler);

ConvertIdToDataSource and ConvertIdToScheduler methods are not described in the documentation.
At least, providing the signatures for the required callbacks would be useful...

Theme issue when program installed on client

Hello,

I created a theme for my radgridview and added it to the theme manager on my form.
Now when I create my installer for my program I added the folder where my themes are saved. So when installing I have my themes on the computer of the client (this case a test computer).

Now when I launch my program I'm getting a message that the theme I want to load for the radgrid doesn't exist on the location.
I checked the path that is shown in the message and it's keeping the path name of where I saved it om my computer.

How can I solve this? Or do I have to add my theme by code to my grid? Then I think I can add something like this?

    
            var mytheme = Application.StartUpPath + '/layouts/mytheme.xml';

Thanks

(I hope that I explained it good)

FilterFunctionBetween seems not to be translated

Hi,

The localization of the GridView works pretty good except that one little Filter Text "Between" gets no localized text. The Property FilterFunctionBetween is set in the XML structure passed to the Grid but nothing happens.

Am I missing something or is this a problem?

Thanks,
Tommy

Problem of ConditionalFormatting

Hi,

I use the Q1 2009 SP1.

If I set a ConditionalFormattingObjectList for a column, the header row cell is colorised, sounds wrong for me.

Perhaps a mistake about GridTableHeaderRowElement, a control is missing?!?

How can I patch this?

Best regards,

Fabien

Feature Request

Does Telerik have any plans to add support for the baseline text snapping on the RadTextbox? The standard windows textbox will show a pink snap line for the baseline of the text in the textbox. So when you are dragging a label around, you can easily align the label text with the textbox text. It would make things a lot cleaner in the designer when laying out forms.

overlapping controls in tab

*Edit* I meant to post this in tabstrip not toolstrip.
I have a tab that includes a dynamically created radpanel and tabstrip, I'm having problems with the panel and tabsstrip overlapping.

    
                Private Sub AddTab() 
        
                    'Add tab to Form 
        
                    myTab.Children(2).Margin = New Padding(0, 0, 25, 0) 
        
                    myTab.Children.Add(newButton()) 
        
                    myTab.IsSelected = True        
        
                    myTab.ContentPanel.Controls.Add(myTreePanel) 
        
                    myTab.ContentPanel.Controls.Add(myTabStrip) 
        
                    myTreePanel.Location = New System.Drawing.Point(0, 0) 
        
                    myTreePanel.Dock = System.Windows.Forms.DockStyle.Left 
        
                    myTabStrip.Location = New System.Drawing.Point(129, 0) 
        
                    myTabStrip.Dock = DockStyle.Fill 
        
                    myTabStrip.Items.Add(innerTab) 
        
                    innerTab.Children(2).Margin = New Padding(0, 0, 25, 0) 
        
                    innerTab.Children.Add(newButton()) 
        
                    innerTab.IsSelected = True 
        
                End Sub
