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.

RadMenu and RadMenuComboItem

I have a radmenu with a sub radmenucomboitem, I want to close themain menu item on the click event of the radmenucomboitem. I have the selected changed event wired to change the theme of the app based on what the user selects however the menu stays on the screen until you click the mouse on the main form. Is there a way to programatically close this?

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....

Can't figure out how to change the selected row highlight for a RadGridView via Visual Style Builder

Update: Figured it, I need to export all the themes as custom packages and then open one, then edit it. This is not obvious!
I'm on the current version of the controls and using a RadGridView to show some data, but it is showing the current row as highlighted in orange.

On other RadGridViews I have removed this programmatically but I'd like to use the Visual Style Builder so I can apply this fix once across my whole project. I just need some help finding it as it is quite impenetrable.

In VSB I've selected Control Default (the theme I want to customise) then drilled down as follows;
RadGridView
RadGridViewElement
GridTableElement
GridDataRowElement
GridDataCellElement

From what I understand, I should be able to set or clear the element state in the top right hand corner window for IsCurrentRow.

This is the confusing bit, it is already there and marked as 'no style'. I would have though it would have a colour applied to it which I would be able to clear.

Is the orange colour being set in a parent item? I've gone up the hierarchy and none of them have a style set for IsCurrentRow.
Perhaps I need the IsSelected?

Where am I going wrong? VSB seems fairly complex so I may not even be looking at the right theme for all I know.

Thanks in advance
