How to change "Animated State Transition" settings in VSB

Hi,

I just started using the new Visual Style Builder (in WinForms 2010.1 10.308), and it's awesome compared to the old way/style.

However, is there a way to change the settings for the "Animated State Transition"?

In some of my older themes, I set very slow animation times to get smoother effects. I used to be able to control the animated transition style and timing. Are these settings still around?

Thanks,

Tim

Menu Command Binding

Hi,

I have added keyboard shortcuts to my menu by using the Command Bindings as follows:

Command Binding : Telerik.WinControls.Keyboard.InputBinding
Chord : Alt + F
Command : ActivateMenuItemCommand
CommandContext : mnuRootFile

This works perfectly the first time I run the App and use the shortcut ALT + F but once I have opened a menu item and close the form the keyboard shortcuts no longer work.

Could you please help me?

Thanks

BeginEdit() on Cell not working from within CellEndEdit event handler

I am trying to validate values being entered into my grid real-time in the CellEndEdit event handler. If I find that the value entered is not valid, I push a message to the user and want to fire the BeginEdit on that same field, to keep them there until they enter something valid.

I cannot kickoff the BeginEdit method successfully on the cell. Sifting through this forum, I found some "like" problems and tried implementing some suggested techniques, all with no success. Below is some sample code.

                    Private Sub grdMain_CellEndEdit(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles grdMain.CellEndEdit         
                     
                If e.Row.Cells(2).Value.ToString <> "" Then         
                    If e.Row.Cells(2).Value.ToString.ToUpper <> "TRUE" And e.Row.Cells(2).Value.ToString.ToUpper <> "FALSE" Then         
                        e.Row.Cells(2).Selected = True         
                        e.Row.Cells(2).CellElement.IsCurrent = True         
                        e.Row.Cells(2).BeginEdit()         
                    End If         
                End If         
                     
            End Sub         

The BeginEdit does not fire, but the cell is selected in the grid.

Regards,

Problems with Custom Theme

Hi,

I've tried repeatedly following the tutorial for modifying the theme of the RadDock, but to no avail. I follow the steps, and the "HotPepper" theme never appears as an option for RadDock. I noticed the sample refered to "DockingManager" and not "RadDock" which I think may be part of the problem.

Am I completely missing something?

Tabbing through Grid skips buttons

I have add and delete buttons within my grid and using the tab key they get passed up and the focus is on the first column on the next line. How can I have my buttons gain focus? I have to make my app fully keyboard friendly. Any other issues I might face with the grid using the keyboard?

Thank You
