To maintain the selection on checkboxes of hierarchy grid

Hi!

I have a grid with hierarchy. The code you can see below:

    
                                    <telerik:RadGrid ID="GridLocalidade" Width="100%" Skin="Telerik" 
        
                                        runat="server" AllowPaging="false" AllowSorting="true" 
        
                                        GridLines="None" AutoGenerateColumns="false" 
        
                                        OnNeedDataSource="GridLocalidade_NeedDataSource" 
        
                                        OnDetailTableDataBind="GridLocalidade_DetailTableDataBind">

                                        </MasterTableView> 
        
                                    </telerik:RadGrid>

In a GridTableView, I have 2 columns as checkbox. If I expand the items, select some checkboxes and after it, I collapse the items, I loose the selection on checkboxes when I decide expand them again, it's due to I always catch the information of items in a database when the user expand them.

Is there a possibility to maintain the selection of user for this scenario?

Radwindow on masterpage

Hi,

I am using radwindowmanager on my webapplication with masterpages. When I navigate to another page, the radwindow disappears.
Is there a way to hold the radwindow (except for the preserveclientstate option, because the window is then reloaded)?

Thanks in advance,
Martin

Rad drag and drop functions

Hi there,

im trying to get the drag and drop functionality to work. im using the code on the demos but im getting the foolowing error:

'Telerik.Web.UI.GridDragDropEventArgs' does not contain a definition for 'DropPosition

Now im aware i probably have an old version of telerik controls in fact version 2008.1.619.35. BUT! the control does let me drag and drop and elements like e.DestDataItem.ItemIndex do exist.

So it must be possible in my version. How is it done?

                            </Items> 
        
                        </telerik:RadMenu>

The default hover image background is appearing from the Skin image rather than css colors. I here by request you to kindly look into this and do the needful ASAP. Kindly let me know if you require any other details.

Thanks,

Colors on image-buttons in default skin

Hi,

I am using the default skin in a grid. The image-buttons in this skin are all in black/white. Is it possible to get them in color without using another skin?

Usually when I disable a button I change the image to black/white but all buttons are already black/white and I cant see if a button is disabled or not...
