Apply Theme to Open Folder Dialog

Hi *,

I follow the docs and use

InitializeComponent(); ThemeResolutionService.ApplicationThemeName = "CrystalDark"; 

Unfortunately my open file Dialog does not accept the theme I set for the application.

Questions:

- is this a right way to set app theme in the ctor of main window (after Initialize component of Course)?

- I would like to use a new folder select dialog by Rad Browse Editor. How to do this?

Thanks a lot

Issue on RadMaskedEditBox

Hi,

We are using RadMaskedEditBox. We have set the mask - (###) ###-#### &&&&&&&&&& & masktype as Standard. The issue which we are facing in this is it is allowing to type the values in the middle of the mask. Can you please suggest a method to restrict it? It should allow me to type from beginning to end. Video link mentioned below for your reference.

tiles fade-in effect

Greetings,

Using the Panorama control , it is possible to design panels similar to Windows start menu panel. But I It would be even better if there had been a fade-in effect for tiles when appearing for the first time. I attached a gif image that I recorded from my Windows 8.1 start menu panel to illustrate what I'm talking about.

P.S I tried making tiles invisible and then making them visible one by one , like every 10 milliseconds, through rows and columns of groups in the control. Not bad, but changing visibility this way isn't smooth as the fade-in effect .

Any trick ?

Progress Bar column: Value1, Value2 and Maximum

Hello.

I've made a progress bar column like it's explained in your documentation: https://docs.telerik.com/devtools/winforms/controls/gridview/cells/creating-custom-cells

Protected Overrides Sub SetContentCore(ByVal value As Object)

If Me.Value IsNot Nothing AndAlso Me.Value IsNot DBNull.Value Then

Me.radProgressBarElement.Value1 = Convert.ToInt16(Me.Value)

End If

End Sub

how can i set the value2 of the progressbar?

and i'd like could modify the maximum value.

i've found:

protected override void CreateChildElements()
{
    base.CreateChildElements();

    radProgressBarElement = new RadProgressBarElement();
    radProgressBarElement.Minimum = 0;
    radProgressBarElement.Maximum = 10;
    this.Children.Add(radProgressBarElement);
}

but in this case the maximum it's diferent in each row of the grid (it is defined by an other field -column- )

would be it possible??

thx very mucht
