Hi!!!
First of all i would like to thank you guys for this excellent looking product.
i have just started making some test apps and i am in a bit of a problem.
Problem...
I have made a elliptical carousel and added some rad image button element. i have been trying to animate these buttons when ever a mouse enters the button element or leaves and if a person double clicks it. The animation includes changing picture to another (to a bigger resolution one), moving the image etc. But strangely i haven't been able too. i know its something very easy, but i couldn't find how to..
Can u please help me quickly with this i would be really thankful.

RadRadioButton and TextWrap property

Does RadRadioButton support text wrapping?

See this picture : if I set or no TextWrap property - text is always in one line.

By the way, if I set proprety AutoSize to True, then False again - text is wrapped, but in designer, not during execution. And after closing/starting Visual Stiudio - text is again in one line.

PS: Same question about RadCheckBox control.

RadComboBox FormatString Not Working?

I'm trying to create a control with formatted entry and a drop-down suggestions list, specifically an am / pm time field with seconds with a list of suggested but not mandatory times. I'm trying to use a RadComboBox and setting its FormatString Property to do this. I couldn't find any docs on this Property so I tried using the Mask characters from the RadMaskedEditBox docs. I've tried "HH:mm:ss tt" and simply "##:##:## LL". In neither case did it restrict values to the specified format or move the cursor to next wildcard section when I tried to type or right-arrow past non-wildcard characters of the mask or press space in front of non-wildcard characters like RadMaskedEditBox does. I've tried setting FormattingEnabled to True and False. Any ideas? Thanks.

BTW, what are the DisplayMember and ValueMember Properties for?

How do I access a grid on a DocumentWindow?

My main form loads a RadDock and a toolWindow containing a PanelBar and RadList.

On clicking items in the RadList a new DocumentWindow is opened. This window is a class which inherits from DocumentWindow.

This loads the document window

    
            LogDocument documentLog = new LogDocument(); 
        
            documentLog.Text = documentTitle; 
        
            documentLog.CurrentFileId = selectedIndex; 
        
            documentLog.Load();  // Loads data into grid 
        
            AirFile.AddNewMostRecentFile(documentTitle, selectedIndex); 
        
            this.radDock.AddDocument(documentLog);

My inherited class (only some of it for brevity)

    
                class LogDocument : DocumentWindow 
        
                { 
        
                    public LogDocument() 
        
                    { 
        
                         AddGridToForm(); 
        
                    } 
        
                    public void Load() 
        
                    { 
        
                         LoadGridWithData(); 
        
                    } 
        
                    private void AddGridToForm()

                        Save(); 
        
                    }

In the constructor I add controls to the document including a RadGrid. When many documents are opened I have a UI similar to VisualStudio.

My Main form has a menu containing a delete button. When this button is clicked I want to delete the current grid row on the current active window.

My difficulty is that I cannot figure out how to reference the "delete item" code in the class LogWindow:

    
                    public void DeleteRow() 
        
                    { 
        
                        // Delete code here 
        
                        // then save changes to db 
        
                        Save(); 
        
                    }

Any help would be appreciated.

Theme and inheritance

Hi,

may be this question has been solved here but I cannot find it in the different threads. I have a class deriving from RadGridView. For example, say the class Grid in the test namespace. In design mode, the ThemeClassName property is set to the actual class name by the designer, so test.Grid in the example. But the problem is that I cannot find the theme names I want in the drop down list. If I force the ThemeClassName property to "Telerik.WinControls.UI.RadGridView", the drop down list is filled with the right theme names but as soon as I save the file the designer reset the ThemeClassName to test.Grid, as I can see it in the file.
So I found the way to force ThemeClassName = "Telerik.WinControls.UI.RadGridView" in the test.Grid constructor but it works in run time only; I cannot see the theme names in design mode.
What is the good way to proceed to apply themes to a derived class ?

thanks.

RadButton ButtonElement and Screen Tip

Hi,

I was wondering why the ButtonElement of the RadButton is not available through the designer. I see that rootElement is, but if I add a screen tip to that, then the screen tip doesn't show, which is quite confusing.

I've had to add a shared method to our controls project to allow us to add screen tips to buttons like so..

    
                Public Shared Sub AddScreenTip(ByVal button As RadButton, ByVal headerText As String, ByVal bodyText As String)  
        
                    If Not button.ButtonElement.ScreenTip Is Nothing Then 
        
                        button.ButtonElement.ScreenTip.Items.Clear()  
        
                    End If 
        
                    Dim Tip As New RadOffice2007ScreenTipElement()  
        
                    Tip.CaptionLabel.Text = headerText  
        
                    Tip.MainTextLabel.Text = bodyText  
        
                    button.ButtonElement.ScreenTip = Tip  
        
                End Sub

It seems strange to have to add screen tips this way. Could a Screen Tip interface be added to the RadButton at it's root level please?
Thanks

Richard

dont allow spaces

I hope this is simple, how can I edit a cell to not allow spaces. The cell is required, and if I hit the spacebar and then enter it accepts it. This is what I have to edit it right now:

private void StateRadGridView1_CellValidating(object sender, CellValidatingEventArgs e)

{

GridViewDataColumn column = e.Column as GridViewDataColumn;

if (e.Row is GridViewDataRowInfo && column != null && column.FieldName == "MntStaName")

{

if (string.IsNullOrEmpty((string)e.Value))

{

MessageBox.Show("Description cannot be blank.", "JMS Error Message", MessageBoxButtons.OK, MessageBoxIcon.Stop);

}

Dynamically load theme assembly

Hi,

is it possible to dynamically load a default theme assembly at runtime an set the theme as application theme. The user should be able to choose between all available themes. Now I have an object for all themes on main form and a reference to each theme. But in order to save loading time I want to load the assembly of the configured theme at application start. I did not found any documentation or sample how to do this.

Regards,

Markus
