Hello,
I have created a silverlight application that is using domain services. I have added the RadGridView control (version 2010.2.924.1040) to one of my pages. It is bound to a table like the one listed below.
LocationID varchar(4)
LocationGUID guid
LocationName varchar(50)
My LocatioGUID field keeps each record unique. However, the RadGridView control is allowing the LocationID (User defined field) to contain duplicates. How can I get the control to keep each entry unique for LocationID?
Thank you.

How to update a cell(type of System.Byte[]) when its value is System.DBNull?
My VB code raise an error:
Dim buffer() As Byte
Dim fsBLOBFile As FileStream = New FileStream("C:\X.Y", FileMode.Open)
buffer = New Byte(fsBLOBFile.Length - 1) {}
fsBLOBFile.Read(buffer, 0, CInt(fsBLOBFile.Length))
Me.RadGridView1.Rows(1).Cells(1).Value = buffer 'Rows(1).Cells(1) is null and collum(1) is System.Byte[] type.

Hello,
We have found an issue in Navigation thru Enter key. We have set following properties
.EnterKeyMode = EnterMoveToNextCelll
NewRowEnterKeyMode = EnterMoveToNextCelll
It works fine until movement from any column have textbox to combobox... If enter is press on textbox column, having next column is combo box, it jump to third column and skip combobox column.
We tried different things and finally write following code to close the Editor.
public override bool ProcessKeyDown(KeyEventArgs keys){if (keys.KeyCode == Keys.Down || keys.KeyCode == Keys.Enter){ GridControl.CloseEditor();
return base.ProcessKeyDown(keys);}
return base.ProcessKeyDown(keys);}Please confirm if this is an issue with latest build.
Thanks,
devoas.

Hello!
We have a window with many documents. Each document puts to the end of the opened documents:
Usually it's working, but when we have no more place for a new tab, the document puts in front of the opened documents. But we always expect to see it as a last document, not first!
Pic.png demonstrates unexpected behavior (fist tab must be Window#1, not Window#3). This problem is reproducing in WinForms docking, ver. 2010.2.10.806

I'm having some trouble figuring out how to use the combobox column. In my gridview i'm trying to display a List(Of OrderLine).
the list is filled with "OrderLine" Objects, with the following property's:
unitcount as Integer,
unitPrice as Double,
product as Product - The product object has an id and name field, being respectively an integer and String.
The product column is the combobox column, and is filled by setting the datasource als a List(Of Product)
When viewing the list, I cant seem to get the product column to show the product name. Furthermore when i try to add a new line, I can't get the value to be the product object either. Is there a way i can set the valuemember as the column object itself, instead of one of its properties?

Is there anything I can do to have a ComboBox behave has a read only element, like you can with a TextBox?
I want to have a field that displays data, but is not always editable, and isn't the hard to read gray-on-gray of the disabled state. I generally suppress the dropdown and then use a light gray back ground with black text, but I don't see anyway to suppress the dropdown.
Is there a way to achieve what I'm looking for?

How can you group off one column but sort on another column through code??
I have one column that has the group name "string" lets say 'ROOM' but the order they need to be displayed is an int lets say "Room Order" so I have data like
Bedroom, 2, 'Some Info1'
Bedroom, 2, 'Some Info2'
Bedroom, 2, 'Some Info3'
Kitchen, 1, 'Some Info1'
Kitchen, 1, 'Some Info2'
Kitchen, 1, 'Some Info3'
Bathroom, 3, 'Some Info1'
Bathroom, 3, 'Some Info2'
I want to group off of the ROOM column but sort offer the Room Order column, however, once I group it always sorts off the group column, in this example ROOM
I have tried bringing in the data already sorted it does help. I have also tried following code:
Me
.gvRoomNights.Columns("ROOM_SORT_ORDER_SITE").Sort(RadSortOrder.Ascending, True)
Dim expression As New GridGroupByExpression("[ROOM_POOL_CD] as [Room Pool] Group By [Room Pool]")
'Dim expression2 As New GridSortField("[ROOM_SORT_ORDER_SITE]")
gvRoomNights.EnableSorting =
True
gvRoomNights.MasterTemplate.EnableSorting =
True
gvRoomNights.MasterTemplate.GroupDescriptors.Add(expression)
Me.gvRoomNights.Columns("ROOM_SORT_ORDER_SITE").Sort(RadSortOrder.Ascending, True)
'gvRoomNights.MasterTemplate.SortDescriptors.Add(expression2)
gvRoomNights.Columns(
"ROOM_POOL_CD").Width = 60
I guess I could group by the ROOM SORT ORDER but I need to change the Groups HEader text to the actual room name. If you can show me that I would be able to get around this. Thanks.
