Slow Scrolling in Grid

Hello,
I need to apply some custom formatting to cells in my grid. Based on the documentation, I have added code to the RowFormatting event of the grid. This works fine as long as there are only a few rows in the grid. Once a get a decent amount of data (60+ rows), then grid scrolls very slowly. I have tried to set the EnableFastScrolling property to true, but the grid still has poor performance when scrolling with the keyboard (up/down keys).

My code in the RowFormatting event is very simple, so I'm surprised that it would cause the performance to degrade so severly. Is there another way to handle this? I tried applying formatting outside of the RowFormatting event, but the CellElement property of the cell is Nothing, so I can't access any of it's properties.

    
                Private Sub rgvLines_RowFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.RowFormattingEventArgs) Handles rgvLines.RowFormatting  
        
                    Dim approval As String = Nothing 
        
                    approval = e.RowElement.RowInfo.Cells("APPROVAL").Value.ToString()  
        
                   If approval = "UNK" Then 
        
                        e.RowElement.RowInfo.Cells("COMM").CellElement.Visibility = ElementVisibility.Hidden  
        
                    End If 
        
                End Sub

Thanks,
Sean

Merge Cells

Hey Telerik team and users!

Its been a while since someone asked for some help related to cells and merging them.
So here I am.
What I'm trying to do is to merge specific cells, I need rowspan and colspan.

I'd love something like: DataGrid.Rows[0].Cells[2].Colspan(2);
Which merges Cells 3,4 and 5 in the first row (zero-based index for the cells) . Looking for something similar to use rowspan ;)

Is that possible that way or the other? I'm quite desperate by now. So there's HtmlView but I'm not quite sure if this does the trick for me. And it seemed to me a bit complicated, to be honest.

I'd be glad for some help and suggestions!
best regards!

Disable Editing in radcombobox

I have a combobox defined like this:

    
            cmbOrigin.Items.Clear();  
        
            cmbOrigin.AutoCompleteMode = AutoCompleteMode.SuggestAppend;  
        
            cmbOrigin.NullText = Transat.PDP.Client.Properties.Resources.ControlDataOriginNullText;  
        
            foreach (MyItem i in ListOfMyItems)  
        
            {  
        
                cmbOrigin.Items.Add(new RadComboBoxItem(string.Format("{0} - {1}", i.Code, i.Nom), i));  
        
            }

I want to have the AutoCompleteMode set to SuggestAppend so that the rest of the text get showed and the list is showed too.
What i dont want is the user to be able to type 2 letters and then hit backspace and go out of the combobox leaving me with an inconsistant value.

how can i force the user to pick a valid entry in the combobox?

thanks
mateo

Alignment of Label Text

Hello,

This should be an easy one. I'm looking to make the X-Axis labels on my grid look identical to the one in your example here:

http://www.telerik.com/help/winforms/buildingdatabinddatabase.html

I have successfully gotten the text rotated, colored, formatted, etc, but the one thing that doesn't work is the alignment. In your example, the text is right-justified, making it hug right up against the bottom of the grid, which is nice! In my case, even when I set

radChart.PlotArea.XAxis.Appearance.LabelAppearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Right;

It still doesn't do that, but stays center justified, so that longer strings run into the chart, and smaller strings are sitting many pixels below the bottom. How do I get my text to be aligned to the right?

Thanks!

Jeremy
