Drag & Drop example

Hi,

I can't find an example for the RadListView and Drag & Drop items for reordering.
I am also missing some visual aids during the drop event like in the GridViews Row Drag&Drop example.

Regards,

How to add an image to Excel while exporting the RadGridView in Winforms

Hello,

I am exporting RadGridView to Excel in Winforms.
In the resulting Excel sheet I need to add an image in the top left cell A1, and some text in cell A4.
I have the code to add the text, but how can I insert an image?

Here is the code from the _ExcelTableCreated event.

// example
void exporter_ExcelTableCreated(object sender, ExcelTableCreatedEventArgs e)
{
SingleStyleElement style = ((ExportToExcelML)sender).AddCustomExcelRow(e.ExcelTableElement, 50, "MY HEADER");

// This is what I need:
// Image img = (Image)Properties.Resources.logo;
// SingleStyleElement style = ((ExportToExcelML)sender).AddCustomExcelRow(e.ExcelTableElement, 50, img);

style.FontStyle.Bold = true;
style.FontStyle.Size = 18;
style.InteriorStyle.Pattern = InteriorPatternType.Solid;
style.AlignmentElement.HorizontalAlignment = HorizontalAlignmentType.Left;
style.AlignmentElement.VerticalAlignment = VerticalAlignmentType.Center;
}

//end of example

Next, I need to turn on the AutoFilter for the Row 2, since my header row now moved down one row. (Ctrl-shift-L shortcut in Excel turns on AutoFilter).

I found the thread about exporting to Excel with autofilter for ASP.NET, but did not locate an example for WinForms.

Thank you in advance!

Reading values from Theme

I'd like to programmaticly read a value from a theme. I've created the following item:

       <Telerik.WinControls.Styles.XmlRepositoryItem ItemType="Gradient" DisplayName="MyNormalControlColor" Key="MyNormalControlColor" Capacity="4">
        <XmlPropertySetting Property="Telerik.WinControls.VisualElement.BackColor" Value="0, 0, 0" />
        <XmlPropertySetting Property="Telerik.WinControls.Primitives.FillPrimitive.GradientStyle" Value="Solid" />
        <XmlPropertySetting Property="Telerik.WinControls.Primitives.FillPrimitive.NumberOfColors" Value="1" />
      </Telerik.WinControls.Styles.XmlRepositoryItem>

If I'm in my code (C#), any idea how to read that value out of the theme to use it when drawing?

Thanks.

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

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.
