it is done but just in Design mode and after Running project eccur an exeption in designer code.
Please notice following code block from my designer code:

// Error Line-->((Telerik.WinControls.UI.GridHeaderCellElement)(this.raGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).IsCurrent = false;//<-- Error Line

((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).IsCurrentColumn = false;

((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).IsSorted = true;

((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).IsPinned = false;

((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).Image = null;

((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).Text = "??? ? ??? ????????";

((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).Font = new System.Drawing.Font("Tahoma", 9F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));

((Telerik.WinControls.UI.GridHeaderCellElement)(this.radGridView1.GetChildAt(0).GetChildAt(1).GetChildAt(0).GetChildAt(1))).Padding = new System.Windows.Forms.Padding(0, 0, 16, 0);

Exception Message:

Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

i cut this code block and past it in the Form Load Event and this problem was solved And this is not that interesting for me.

UseMnemonic in MenuItem

Hello,
I'd like to use an & in one of my menu items, but can't as UseMnemonic doesn't seem to be accessable. I have tried setting a TextPrimitive first and serting the text of the menu item to that, but that doesn't seem to work. I can't use && as this cuts off some of the text. How can I use UseMnemonic in the text property of a MenuItem?

Thanks

Databinding on SelectedIndex property

Hi I'm using Q3-2010 and I have installed the latest Service pack released yesterday and it has made no difference.

The problem I have is when I bind to the "SelectedIndex" property of the DropDownList. It works fine with other properties like "Text" but not with selectedindex.

Any suggestions please ?

Regards

Paul.

Nested Context menus on a radGrid

I've got a basic context menu working on a RadGrid, but I want to include a 3rd context menu (with the arrow character >) that nestes and has a bunch of other menu items on its own menu panel. Would that need to be a combo box item?

What I have working so far is this (pretty basic context menu):

Dim contextMenu_Active As New RadContextMenu

Dim menuItem1 = New RadMenuItem("Stop")

menuItem1.ForeColor = Color.Red

AddHandler menuItem1.Click, AddressOf menuItem1_Click

Dim menuItem2 As New RadMenuItem("Remove")

AddHandler menuItem2.Click, AddressOf menuItem2_Click

contextMenu_Active.Items.Add(menuItem1)

contextMenu_Active.Items.Add(menuItem2)

Private Sub RadGridView_Active_ContextMenuOpening(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.ContextMenuOpeningEventArgs) Handles RadGridView_Active.ContextMenuOpening

If TypeOf Me.RadGridView_Active.CurrentRow Is GridViewDataRowInfo Then

e.ContextMenu = contextMenu_Active.DropDown

End If

End Sub

Private Sub menuItem1_Click(ByVal sender As Object, ByVal e As EventArgs)

Dim index As Integer = Me.RadGridView_Active.Rows.IndexOf(TryCast(Me.RadGridView_Active.CurrentRow, GridViewDataRowInfo))

If index >= 0 Then

Dim strGUID = Me.RadGridView_Active.Rows(index).Cells(0).Value

Try

ccJob.JobStop(strGUID)

Catch ex As Exception

End Try

End If

End Sub

Private Sub menuItem2_Click(ByVal sender As Object, ByVal e As EventArgs)

'TODO

End Sub

Chart Title customizing

1. When I render a chart on the screen I simply want to display the chart title at top left, such as:
(Chart Title)

2. However, when that chart is printed, (using RadChart.Printing.PrintChart()), I want the date printed as well, but right justified, and not as impacting, such as a smaller font or italic, such as this:

(Chart Title) Date Printed: 1/13/2011

Is this possible? I figure I could simply add the date printed part to the chart title text when a user prints a chart, and then remove it when printing is completed. However, that doesn't resolve the issues of a different font and right justification.

Can a chart have multiple titles, like a ChartMainTitle and ChartSubTitle? I think that would be the best solution, cause of course each could then be set up completely independently of each other to satisfy all user requests. If this isn't possible, could the feature be added to a future version?

Thanks much,
Dan
