Hi

I'm trying to retrieve a list of special days held in a table on an SQL server and use those dates as Special Days - how do I do this? I can retrieve the dates into, say, a dataset or gridview but I'm unclear how to then add these as Special Days at run time.

Also I have some code I found that completely disables Sundays on the calendar. How can I adapt this so the same applies to any Special Days? I ask because the code completely greys out Sundays yet Special Days are still 'clickable' and I want them to also be greyed out.

Here's the code:

Dim calTable As

Telerik.WinControls.UI.CalendarTableElement = TryCast(RadCalendar1.RootElement.Children(0).Children(0).Children(2).Children(0).Children(1), Telerik.WinControls.UI.CalendarTableElement)

If calTable IsNot Nothing Then

For Each cell As Telerik.WinControls.UI.CalendarCellElement In calTable.Children

If (cell.[Date].DayOfWeek = DayOfWeek.Sunday) Then

cell.Enabled = False

End If

Next

End If

Thanks for any help

Suitable Import namespace for examples

I am trying to replicate the code listed in the examples fro importing a file to a richtextbox, like

Dim document As RadDocument = Nothing
Dim provider As IDocumentFormatProvider = New DocxFormatProvider()
Dim openDialog As New OpenFileDialog()
openDialog.Filter = "Documents|*.docx"
openDialog.Multiselect = False
Dim dialogResult As DialogResult = openDialog.ShowDialog()
If dialogResult = System.Windows.Forms.DialogResult.OK Then
Using stream As New FileStream(openDialog.FileName, FileMode.Open)
document = provider.Import(stream)
End Using
End If
Return document

I am unable to find what are the correct namespaces for RadDocument and IDocumentFormatProvider,

I have tried

imports telerik.wincontrols
imports telerik.wincontrols.ui

etc, but I am kind of lost,

Can you please provide some help?

Listbox Column (Editor) with MultiSelect

Hello,

I'm searching and looking for a solution or idea howto implement a Listbox column with MultiSelect in GridView.

We want cover this aspects:

a) GridViewCell.Value holds an Array of String
b) GridViewCell show a concatenated String of Value
c) Edting cell opens an editor with a RadList control and MultiSelect; MultiSelect handles Shift and Ctrl
d) Editor closes on Popup-Button Click or LostFocus of Popup

First choice was to use GridViewMultiComboBoxColum and depending Editor/Element. But Popup closes on first Click. May be we can overwrite this behavior?

Otherwise in my mind I have to do:

1.) Create new GridViewCellElement, covering Array value and display of it
2.) Create new GridViewColumn with depending Editor/Element

The second part I tried to inherit PopupEditorElement, but got the ListElement not shown in Popup. Popup was always empty. May be I can handle it in the right way?

Please send any hints that let me go on the right track!

Regards from Leipzig
