This is probably going to seem pretty easy to some of you but I haven't been able to determine what the cause of this problem is. If I try to set a RadListDataItem object and add that object to multiple DropDownList controls it doesn't work. For instance, I have a simple For/Next loop that enumerates a list of COM ports. Seems to me that I should be able to do a simple loop and add the items as shown below but it doesn't work. Only one of the DropDownLists gets the data. I'm sure it has something to do with the way the control is handling the dataitem objects. I'm hoping someone can explain it to me and give a work around other than creating two For/Next loops (one for each DropDownList).

Thanks!

For i As Integer = 0 To 9

Dim oItem As New RadListDataItem

oItem.Text = "COM" & i

oItem.Value = "COM" & i

rddReceiveCOM.Items.Add(oItem)

rddSendCOM.Items.Add(oItem)

oItem = Nothing

+ - does not display when new row is added.

I have a RadGridView bound to a DataTable. When I add a new rows of data to the DataTable, they parent row in the hierarchy does not display the expand / contract graphic by default. It does appear after I click on the RadGridView however. I tried using:
this.radGridView.Invalidate();
to force a redraw but it does not work.

[Update]
Attached is a screenshot. The top image represents the grid when row is added to datatable, the bottom image represents the grid when the user selects a cell from the grid.

Problem with GridView sorting on date column.

I have some dates in a Rad GridView. I can never get to sort them in the correct order. I clicked on the property builder and set the sort order as Desecending for that particular date column. Is this a problem everyone face or any thing else needs to be done. How do we add a sort expression for a rad grid in winforms. I am using Q3 SP 2010. Thanks a lot for your help.

Visual Inheritance

I'm building an application with extensive visual inheritance. I have a Base RadForm. I need to have Windows7 theme application-wide. All forms inheriting this form have the correct theme but all controls that I place on the inheriting form are not picking the theme. How do I go about this? Need to manage theme for every Telerik control while using visual inheritance.

Edit: Here is a sample project. It has no theme (default blue theme) at the moment. I need Windows 7 theme (example) across the application but I want to set it through the BaseRadForm. One location to update theme application-wide.

Modify Existing Themes

I would like to modify one of the existing themes in my project. Can I extract one of the built in themes and modify it with a different name. Is this even possible? I am mainly concerned with the Radform theme.

Problems with RulerScaleSize in weekview

I have a RadScheduler (RadScheduler1) set to weekview and setting the RulerScaleSize to 15, and the ShowWeekends set to false. On the form I have a checkbox (chkShowEnds) for "Show Weekends", with the following code in it's click event.

Dim weekview as SchedulerWeekVview = Me.RadScheduler1.GetWeekView()
weekview.ShowWeekend = Me.chkShowEnds.Checked

It set the ShowWeekends property, and the RadScheduler weekends appear and disappear correctly. However, on the first click it sets the RulerScaleSize to some default setting of about 25 or so, and I can not seem to set it back to 15. I tried testing around with setting the RulerScaleSize and it seems to set to a larger value, but not smaller ones. It also seems to change the RulerScaleSize the first time, but not subsequent times.

Any help woul dbe appreciated.

ContextMenu for ListBox Item

I have a list box with some items in it. I have a ContextMenu assigned to the ListBox

I want to add logic to the "DropDownOpening" event so that the menu only displays when an ITEM is right clicked, and that is contextual for that item.

I don't seem to be able to work out how to retrieve the item over which the right click was made.

I've tried listBox.SelectedItem but that doesn't work as the right click isn't moving the selection

I've also tried listBox.GetChildAtPoint(contextMenu.DropDown.Location) - but that always returns null

Any help greatly appreciated.
