Hi,

Is it possible to add shadows to my radforms ?

Thanks for your response

The MultiColumn ComboBox is always selecting a value after data is added to it. Is it possible to have it work almost exactly the same as the DropDownList?

For i As Integer = 1 To 12

    Me.MultiColumnComboBox1.EditorControl.Rows.Add(i, "Row " & i)

    Me.RadDropDownList1.Items.Add(i)

Dear Admins.

I was Using the following code for populating radGridView. But it was little bit slower (items Count was more then 40,000)

Then i give a try to use VirtualGrid (By using the Example given in the Documentation), to check the performance difference.it is good.

I have some question regarding presentation/ populating of VirtualGrid.

The ItemClass is used to populate the VirtualGrid have 15 columns(Attributes),

1. I want to load only some of them, Locating at different Column Numbers not in Sequence. Like i have Column Number from 1...15, I want to display only 1,3,6,10th Column Numbers(Index Numbers).
2. How to Hide any Column which is already populated in the Grid.
3. I want to make custom filter functionality. I Have a Text Box above the VirtualGrid. I want to use that TextBox to apply the Filter on the Grid by Typing the Item Name, and Grid filter the Number of items according the typed text and display in the grid.
4. How to Clear VirtualGrid rows.

I can use these functionalities by using the radGridView, but due to performance i want to use Virtual Grid.

I have achieved this behavior using the Microsoft DataGridView. But due to Conversion. I want to use all the controls only from telerik. (Using R2 2019 SP1)

If possible any working example will be appreciated.

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.

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 ?
