hi,
i have the latet download (yesterday) on the winform control.

I founf this bug, let me explain

I have data from a Datatable bound to the grid.  A simple code, decription.  I wnt to be able to add new codes and descriptions but once added I want he code to be readonly.  So I add this code to the form


    Private Sub rg_States_CellBeginEdit(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellCancelEventArgs) Handles rg_AssumptionGroupsTypes.CellBeginEdit
        'Cancel edit if we are on an existing row and column 0
        ' turns the State abr to readonly
        If e.RowIndex > -1 Then
            If e.ColumnIndex = 0 Then
                e.Cancel = True
            End If
        End If
    End Sub

The purpose of the code is to check if the current column is 0 and we have a rowindex then I want to cancel the edit using the GridViewCellCancelEventArgs method cancel

This is great works first time but if you click very fast on the cell it exceptions . 

Here is the error

System.NullReferenceException was unhandled

I have found other bugs in the grid as well but this one is cheesing me off.

I'm using the following code to set the current row in the RadGridView. When I set the CurrentRow property, then get it directly after, I'm finding that the CurrentRow is never the same as the row that I set. The code is always returning true though, so the set is happening. I've tried this after the DataBound event happens and still it doesn't work. What am I doing wrong?


I've even tried this.CurrentRow = this.Rows[2] and it's not working.

Instead of having long, single line buttons, I would like to have multiple lines but I cannot figure out the magic.

Hi,

I have two quick questions pertaining to the ShapedForm and RibbonBar.  Firstly, when I click on my app's button in the Windows task bar, it maximizes it like it should.  However, when I maximize another window - one of any other application - Vista does a growing-like effect from the bottom of the screen which it applies to the window.  Also, when I click a window again, it will minimize using the opposite transformation effect.  However, in my rad.Controls-powered application, no minimization occurs during this process, let alone with the integrated Vista effect.  Do you guys know about this?  If so, is there a workaround or upcoming fix?

Secondly, when I right click the title bar or task bar button of a standard application, it opens a context menu with the options Restore, Move, Size, Minimize, Maximize, and Close.  In my application, however, this context menu appears neither when I right click the RibbonBar or the task bar button.  Again, is there a way to resolve this issue?

Are these problems caused by the usage of ShapedForm, or what?  Thank you very much for any help you can provide - this stuff is really frustrating me!

Dear sir,

Hy,

we had 2 projects where we had older Telerik controls in use. Now we installed the new Telerik Controls for Windows Forms and have major problems with this.

Some smaler problems was that some black writing on white background was now white on thite background.

But the bigest Problem ist that ist nearly impossible so get into the Form.cs[Design]. Only if you get the latest Version 2 to 3 times you can work with the Design for about 1 hour.

The arror message ist

	One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.

I hope someone can help me.
