I set the datasource to a query ( CatQuery)

This loads the control with 2 columns- serialID and catText

How do I get these two values of the selected item of the dropdown.  

Thank you

This is probably a very trivial issue, but - just starting with UI for Winforms - I am unable to access the data apparently loaded in the workbook below  (what I am trying to do is to load an excel file in a Worksheet to use it in a datatable)

When I run this, it goes well, but the only output displayed by the Debug.Writeline instruction is :

 "> Telerik.Windows.Documents.Spreadsheet.Model.RangePropertyValue`1[Telerik.Windows.Documents.Spreadsheet.Model.ICellValue]"

Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click

        Dim fileName As String = "C:\Users\patrick\testfile.xlsx"
        Dim MyWorkbook As New Telerik.Windows.Documents.Spreadsheet.Model.Workbook
        Dim WorkbookFormatProvider As New XlsxFormatProvider()
        Dim MyInput As New FileStream(fileName, FileMode.Open)
        MyWorkbook = WorkbookFormatProvider.Import(MyInput)
   
        Dim MySheet As Worksheet = MyWorkbook.Sheets.ActiveSheet
        RadSpreadsheet1 = MyWorkbook.Sheets

        Dim Res As String = MySheet.Cells(1, 1).GetValue().ToString
        Debug.WriteLine(" > " & Res)
       
    End Sub

Can someone be kind to tell me what I do wrong ?

Thanks

Hi,

I'm trying to render HTML data as a title in the dock window caption element. Although it renders the HTML data as expected, it does overlap with the Window State & Dock buttons. I tried applying text trimming using CSS properties but It didn't work. How to avoid overlapping?

Attached a sample

Thanks

Hi

I want to display report using radtreeview controls. Can somebody help me regarding that i am new to radtreeview control. Currently I am using radgridview to display report.

Thanks 

I have a PropertyGrid with 2 types of editors ; SpinEditor and DropDownListEditor. After the user changes a value in a SpinEditor, it triggers the event PropertyValueChange. However, after the user selects a new value in the DropDownListEditor, it does not trigger the PropertyValueChange. The ValueChanged event is fired but the new data is not saved in the item at this point. 

How can I make it trigger the PropertyValueChange event after the user changes the value in the DropDownList?

Thanks!
