from current row to next row by Enter key in group and filter

Hi :
     The radgridview enable group and filter. The user want to skip the next row from current row and the next row into edit mode by Enter.
       1. Our code as follows to achieve the enter key, :
        private voi dg_KeyUp(.....)
        {                  ......
              if((dgCut.CurrentRow.Index+1)<dgCut.Rows.Count)
              {
                     var row =dgCut.Rows[dgCut.CurrentRow.Index+1];
                     dgCut.CurrentRow=row;
                     if(dgCut.CurrentCell!=null)
                     { dgCut.CurrentCell.BeignEdit();}
               }
         }
      but if there is a filter by column 'Name', the enter key event behavior is strange.The current row can not skip to next row.

      To solve the problem with filter,we update the code as follows:
        private voi dg_KeyUp(.....)
        {                  ......
              if((dgCut.MasterView.CurrentRow.Index+1)<dgCut.MasterView.Rows.Count)
              {
                     var row =dgCut.MasterView.Rows[dgCut.MasterView.CurrentRow.Index+1];
                     dgCut.MasterView.CurrentRow=row;
                     if(dgCut.MasterView.ViewTemplate.CurrentColumn!=null)
                     { dgCut.CurrentCell.BeignEdit();}
               }
         }

      the result as we do is :it is Ok by Enter key if there is only exsit filter.It is not Ok if there is group and filter.
     How to achieve the enter key behavior if there is  a group or multiple group and a filter or multiple filter?

Greetings
Look forward to you

Tree View drag and drop issues

We are using telerik control in our Excel-Addin Application.

Functional working: we launch a form on clicking the button ("open form") at add-in ribbon. User will drag the tree nodes to spreadsheet cells.

Issues we face
1. We don't want hint of node when we perform the drag and drop on spreadsheet cell. (Version used 2010.1.10.504)
2. We tried to use the new version DLL from Telerik but some serious issue arises (Version used 2011.2.11.831)
a. item drag event is getting called multiple times.
b. Cursor remains the NO cursor after dragging the node to area of spreadsheet

Code written on item drag event is as follows

Private Sub RadTreeView1_ItemDrag(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.RadTreeViewEventArgs) Handles RadTreeView1.ItemDrag

If Not IsNothing(RadTreeView1.SelectedNode) Then

Dim strSelected As String = RadTreeView1.SelectedNode.Text

RadTreeView1.DoDragDrop(" ", Windows.Forms.DragDropEffects.Copy)

Globals.ThisAddIn.Application.ActiveCell.Value = "LB (" & "" & ControlChars.Quote.ToString() & strSelected & ControlChars.Quote.ToString() & "" & ")"

End If

End Sub

Please do provide the solution.

Got a notification to upgrade, so I did...I have 3 projects under my solution, 2 of which use Telerik WinForms...one project updated just fine, the other fails...I get the following error message:

Error executing custom action
Telerik.WinControls.VSXActions.UpdateReferencesAction: Object

Adding Multiple Header Rows at Runtime in RadGrid

I need to build a grid with 2 header rows where each column in the 1st header row groups few columns in the 2nd header row.
And the 2nd header row is in 1:1 relation with the grid columns.

For example:

Sunday			Monday
Morning	Afternoon	Evening	Morning	Afternoon	Evening

How do I implement that in RadGrid?

Thanks in advance.

RadGridView horizontal scroll not working :(

Hi guys,

Im only just starting to use Rad controls for winforms, and i know i have such a stupid question. But how do i get a horizontal scroll bar to work with the RadGridView. Il explain my problem below:
Eg - i have 10 columns in the grid, and havent actually set any specific widths on them, and call

radGridView1.MasterGridViewTemplate.BestFitColumns();

Now when i click one the columns to make it autosize to fit its contents, eg a column that has a long sentence in it, i expect to see a horizontal scroll bar so that i can stil scroll to view the other columns. But unfortunately the scroll bar never shows up :( Even though HorizontalScollState = AutoHide. All i simply want is for a scroll bar to show up when there are too many columns.

I must be missing something for sure! Do i need to set specific widths on columns, so that the scroll bar comes up and works?

Thanks for any suggestions.
Chris.

Removing table borders

Hi,

I am using the RadRichTextBox (RRTB) to display HTML code. This works well, however there is an issue with the border of the table with which I am unable to remove, and remains black between cells. I have tried to use iinline attributes such as style="border:none" and style="border-collapse:collapse" without success.

Are any style attributes for tables supported? Please help!
