Problem with Q3 2008 SP1 and MultiSelect

I recently upgraded to Q3 2008 SP1 RadControls, and now am observing the following issue. If I enable MultiSelect on my grid, and then right-click below the existing rows (in the blank space after the last row) on the grid, I get an exception:

"Object reference not set to an instance of an object"

Through process of elimination, I was able to determine the exception is occuring only when MultiSelect is set to true, and am able to reproduce in a sample project as well. Multiselect is an important feature in my application, is there a workaround for this bug?

Thank you,

Rachel

Screen Tips (All Controls)

I was quite happy to see this addition in Q3 after waiting for it expectantly.

However , I cannot get it to work. I am adding screen tips as I always did
on the ribbonbar control previously (always worked fine). The screentip
never shows when I mouseover the control (radbutton).

I decided to trap the screentipneeded event and found that even though
the screentip was present in the designer, that the event found the item
to be a null.

I then tried programatically adding the screentip on application startup ,
this time the event showed that the screentip was not a null but a valid
screentip. Still the same problem though , the screentip never shows.

I assume I am missing something simplistic but I am doing nothing any
differently from before.

Can we access the EditAppointmentDialog ?

Can I access properties of this dialog? For example, make the recurrence button invisible, seen as I can't save a recurrence rule.

Thanks,
Derek.

Gridview columns resize

Hi,

when I set the columns in a gridview to autosize, initialy everything looks fine. But when the form and thus the grid is resized, the most right columns starts growing and will eventually be the only visible column.
This also applies when the grid is not resized but redrawn. It seems there's something wrong with the calcualtion of the column widths. Is this a known issue?

DockingManager.BackgroundImage disappeared

In my main MDI RadForm, I added a DockingManager. To enhance the application's appearance, I added a background image to the DockingManager via the BackgroundImage property. So far so good, the background image showed up fine.

Then I created a DocumentPane and attached to DockingManager via the SetDocument() method (via code). Also this is working fine. However when I clicked on the close button on the DocumentPane, the background image disappears. I looked at the BackgroundImage property and found the Image still there, just not being drawn or being covered by something else.

I tried several methods such as Refresh, Update, Invalidate on the DockingManager but got no result.

Any idea?

Thanks,

Phi

color the background of a cell

Hello,
Could you help me with this:
When a cell is selected in my grid, i would like its backcolor to change to "Selected color".
And when another cell is clicked, the previous cell change its backColor to "Original color".

All of this is working when I insert this code:

    
            Private Sub GridViewPrepack_CellClick(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles GridViewPrepack.CellClick 
        
                    'Get the right cell and the columnName 
        
                    Dim myNewSelectedCell = CType(sender, GridCellElement) 
        
                    Dim columnName As String = myNewSelectedCell.ColumnInfo.HeaderText 
        
                    GridViewPrepack.CurrentRow.Cells(columnName).CellElement.BackColor = Color.Red 
        
                End Sub

Here is what i don't know how to do:
There is a commandCell in my grid, and I when i click on it, i want the color of my previous selected cell to stay to "Selected color"
I try to put a condition saying : " if its the command cell, leave my previous selected cell colored"
But it doesn't work.
Can you tell me how to do it?
thank you
