[Solved] 2 sets of tabs on Document Window

I'm using a RadDock and DocumentTabStrip to have tabbed documents and wanted to know if it was possible to do something like in the image I attached. Basically where the top tabs would toggle which document is shown, but then also have 2 tabs along the bottom to toggle between 2 different "states" each document has. The idea is similar to a web page design tool where each top tab would represent a web page, and the 2 bottom tabs would allow you to switch between raw HTML text view and the actual rendered page. Is this possible?

Thanks,
--Jason

Conditionally format cell value based on value of another cell

Hello,
I want to format a cell value in a GridView for WinForms. The format style depends on the value of another column cell.
I tried something like this:

Private

Sub gvMessages_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles gvMessages.CellFormatting

For Each row In Me.gvMessages.Rows
If row.Cells("Type").Value = "S" Then
row.Cells("Element").CellElement.BackColor = Color.Aqua
Else
End If
Next

But it did not work. Could you please give me a hint or a link for a solution.
Thnak you very much
Roberto

[Solved] RadTextBox cursor position changes when TextChanging event is cancelled

I'm not sure if this is a bug or by design. I handle the TextChanging event of a RadTextBox to prevent users from entering invalid characters. If they enter an invalid character, I set e.Cancel to false. While the text does not change, the cursor returns to beginning of the textbox. This is annoying if you don't notice you typed an invalid character. For example, if I were typing "Hello, world" and canceled the event as the space was typed, the TextBox would now read "worldHello,"

If it matters, I haven't upgraded to Q2 yet.

SQL to limit selection

I have an embarrassingly simple question.

I'm new to the RadGridView but need to build something for a customer. I have done a mock up of the interface using the built in Project Datasource to show how the grid will work. ( hierarchical presentation etc) and using SQL Database. This was all nice and straightforward.
But now I need to build the actual application using customer selected parameters to form the SQL query. ( does not change the columns, just changes the data returned).

Do I need to completely change the datasource type or can I adapt the DatasetGenerator to update the SQL statement. I have tracked down the CommandText , but this is all private to the class.

What the best approach to use? I have a master and 1 sub level of data to get or if the user selects to see the data in another way, a completely separate data set to query and display ( with different columns and no hierarchical data).

Thanks a million.

Self Referencing Treeview loses children in RadDock

Hello all

I've got a strange one. I've got a treeview with check boxes in a tool window in a RadDock.

When I change the docking on the window, the treeview loses its children. The parents stay, but the children are gone - there are no children at all and the parent node doesn't expand.

As a work around I tried reloading the treeview after the dock state changes, but then the children get reloaded, so that every time I dock I get a new set of children nested inside the existing children. I've tried clearing the treeview and setting the data source to nothing before reloading. Here's the code:

Private Sub DockMain_DockStateChanged(sender As System.Object, e As Telerik.WinControls.UI.Docking.DockWindowEventArgs) Handles DockMain.DockStateChanged

Filter_Equipment.BeginUpdate()

Filter_Equipment.DataSource = Nothing

Filter_Equipment.Nodes.Clear()

'Filter_Equipment.Nodes.Refresh()

LoadEquipmentTreeView()

Filter_Equipment.EndUpdate()

End Sub

Private Sub LoadEquipmentTreeView()

Filter_Equipment.DataSource = _Context.FindEquipmentType(Nothing, Nothing, Nothing)

Filter_Equipment.DisplayMember = "EquipmentTypeName"

Filter_Equipment.ValueMember = "EquipmentTypeID"

Filter_Equipment.RelationBindings.Add(New RelationBinding(_Context.FindEquipment(Nothing, Nothing, Nothing, Nothing, Nothing, Nothing), "EquipmentShortName", "EquipmentTypeID", "EquipmentTypeID", "EquipmentID"))

Filter_Equipment.Nodes.Refresh()

End Sub

Some screenshots attached - I have blocked out the values displayed in the nodes because it's client data, but hopefully you can see.

Any suggestions?

Thanks in advance....
