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!

Very simple problem. 

How to get a CLB with only one item ever checked? There's a simple property to allow only single-select, but not one for 'only allow one box to be checked at a time'

How to do this, from inside the 'ItemCheckedChanged' event handler, without causing a stack overflow, as the previously cheked items are un-checked?

I feel this must be really easy - am I just missing something?

Hi,

I'm looking for a way to forbid resizing a task but allow users to move them to another time.

If found issues about blocking events (https://www.telerik.com/forums/how-to-disable-edit-add-new-delete-items), but it implies to "cancelstart" on the dragDropService.

I can't find an event that gives me enough information to choose between "allow" and "cancel" modification if its "move" or "resize"

ps: I had to remove packages of the solution so it respects the 20MB limit, hope that won't cause any trouble.

Thanks for your time and help.

Simon.

hi 

what bottom border text box control not show after enable Embedded Label

I would be great if the RadProgresBar control was a bit more tolerant of values whih are > max value.

OK, so this is a programming errot, but the error message the user sees is a bit extreme - a .NET error.

Perhaps the Telelrik framework might just ignore these values which are > max value , and just set to 'max value'.
