Changing background color of column headers

How do I programmically change the background color of the column headers in a DetailsView ListView? I know there is a VisualItemFormatting event, but I am not sure if the headers pass through this event.

RadContextMenu not painting properly

Morning,
Before I log this as an issues, I want to ensure that what I am doing is correct. I am using the RadTreeView with 3 levels of node and I am dynmaic assigning context menus based on the level.

private void RadTreeView1_SelectedNodeChanged(object sender, RadTreeViewEventArgs e)
{
    if (e.Node.Level == 0)
         {
                 e.Node.ContextMenu =ContextMenu1 ;
         }
     else if (e.Node.Level == 1)
        {
                 e.Node.ContextMenu =ContextMenu2;
        }
     else (e.Node.Level == 2)
        {
                e.Node.ContextMenu =ContextMenu3 ;
        }
}

When I right click on the level 2, my context menu works perfect. When I right click on any other level, I get a single line of pixels which I believe is my menu. Am I doing the correctly?

Thanks

James

Multiple timeworks. How to??

Hi. I'm writing a medical schedule system and I am using the Winforms Scheduler control. Each doctor has diferent working days and each day can have several timework.
For instance, in Mondays Doctor A works from 9:00AM to 12:00AM in the morning and from 16:00PM to 18:00PM in the afternoon, On Tuesday, Wednesday and thursday he doesn't work and in Friday he works from 12:00AM to 14:00AM in the morning and from 18:00PM to 20:00PM in the afternoon.
I would like to draw that working hours in the scheduler control and disable every hour out of his working hours so the user can't create an appointment in that time.

How can I do that??

Thanks
Javier

progress bar column's problem

Hi Telerik Team
     I use version Q2 2009.
     I use following code to add progress bar as a column
"            if (e.CellElement.ColumnInfo is GridViewDataColumn && ((GridViewDataColumn)e.CellElement.ColumnInfo).FieldName == "Progress")
            {
                if (e.CellElement.Children.Count > 0)//the progress bar is already added to cell
                    return;

                RadProgressBarElement element = new RadProgressBarElement();
                element.Minimum = 0;
                element.Maximum = 100;
                element.Value1 = 70;
                element.Value2 = 90;

                e.CellElement.Children.Add(element);
            }"

Everything seems to be OK, but when windows bar is scrolled down and scrolled up, the sequence of progress bar is changed.

I find that someone said it is because some cells are reused to make radgridview be quick.

Can you give me a solution to make progress bar column didn't change when windows bar is scolled down and up.

Thank you very much.

Highlight cell text

Hello,

Is it possible to change the BackColor of a set of characters in a cell in order to highlight search results? I know I can change the background of the cell but I would like to highlight the text as Outlook does when you are searching for an email. Thank you for your help.

Show the datetimepicker in dropped down mode when a gridview cell is selected

I have a RadGridView in Winforms and a date time cell which when clicked will show the text edit mode and a drop down arrow to the right. On clicking the drop down arrow the nice calendar date picker shows.

I'm trying to get the calendar to show straight away but can't find a method on the calendar object. My current code is as follows;

Private Sub OrderGridView_CellEditorInitialized(sender As Object, e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles OrderGridView.CellEditorInitialized

Console.WriteLine("Editor init: {0}", e.ToString())

Dim editor = TryCast(OrderGridView.ActiveEditor, RadDateTimeEditor)

If (editor IsNot Nothing) Then

Dim calendar = DirectCast(editor.EditorElement, RadDateTimeEditorElement)

calendar.GetCurrentBehavior().DateTimePickerElement.Visibility = Telerik.WinControls.ElementVisibility.Visible

calendar.PerformClick()

calendar.Select()

End If

End Sub

Is there a way to do this? Perhaps if not possible, I'll fake a click to the drop down button.

Thanks in advance

Programmically reordering columns

I have a simple class that I am binding to a RadListView. Is there a way, after binding occurs, to programmically reorder the columns? I want my ID property field to always show first, followed by the rest of the fields.

Thanks,

Alan
