CellFormatting doesn't allow BackColor to be set?

I posted this before but the post seems to have vanished

    
            void TelerikRadGridViewEnhanced_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)  
        
                    {            
        
                        if(!(e.CellElement.RowElement is Telerik.WinControls.UI.GridTableHeaderRowElement) && TextColorOverrideFunction != null)  
        
                        {  
        
                            e.CellElement.ForeColor  = TextColorOverrideFunction((e.CellElement.RowInfo.DataBoundItem as DataRowView).Row);  
        
                        }  
        
                  }

This works fine and sets the foreground (text) color. However despite there being 4 BackColor properties, I can't change the back color, it is overridden by the theme. Is there a way to set the BackColor? Thanks

Bug or Feature?

Hello,

some minutes ago I discovered a behavior on GridView which let me struggled for some time. The background is, I fill the rows with data and set the Tag property of row to my data object. After calling GridView.Relations.AddSelfReference the type of rows changed from GridViewDataRowInfo to GridViewHierachyRowInfo. Cell data is copied, but Tag value is missed. As I saw in the Constructor of GridViewHierachyRowInfo the data cache is only copied. In my mind also the Tag data schould be copied?

My workaround is to build a separate Dictionary with the key on my data object, also used in the hierachy. So I can access the data, which should be stored in Tag property, now from Dictionary using the value of ny ID column in GridView.

Same behavior can also be discovered on Tag property of the Cells.

Regards from Leipzig

Feature request Timeline grouped view - change resource height!!

Hi Telerik Team

Im using Radscheduler (2012.1.321.40) in a customer project and need to render multiple appointments e.g. "unassigned Tasks" in the first Grouped Resource "Unassigned" which is kind of a virtual resource from where appointments can be assigned to real resources by drag+drop operation.

Therefore I need to be able to set the height of the first grouped Resource "Unnassigned" (e.g height of 10 appointments) without the need to scroll cell content. The height of the other grouped resources (swimmlanes) should be settable also (min+max/auto where auto is current behaviour where available space is divided by number of grouped resources)

If total height of visible grouped resources exeeds the available space in Y-Axis, a scrollbar should allow for vertical scrolling.

What do other think about such a feature?

The only way to achive this behaviour at the moment would be adding a radSplitcontainer to the form, add add two radscheduler to it.
But then you need to sync viewsettings, visible scrollarea and need separate datasource which makes searching|filtering more complex...

Remember location of specific toolwindow

Is there any possible way to remember the location of specific tool window to keep its location after closing and restarting the application.
I need to do this for specific tool window and not for other doc windows in the rad dock control since the other windows are created dynamically.

Drag and Drop one gridview to another bound to a SQL Datasource

I've downloaded the most recent trial version of Winforms and I’m testing several new features including the enhanced drag and drop (specifically from Radgridview to another radgridview). I've found several older unbound implementations on your website and I'm having troubles adapting them to using the most current version.

Is there a SQL bound example of this feature that someone can point out (in VB please) that uses the most recent version (2012 Q1) that I can review and build from for testing?

Thank you.

Thanks!
