Hello! 

I have a question about the RadContextMenu. I created my class DataGridView so this class inherited from RadGridView. If I add contextMenu with    RadContextMenu.SetContextMenu(this, contextMenu) can't add new contextMenu. Look this:

public class DataGridView : RadGridView
{

   public DataGridView()
   {

          // create menu
            var contextMenu = new RadContextMenu();
            RadMenuItem item = new RadMenuItem();
            item.Header = "Hello";
            contextMenu.Items.Add(item);
            contextMenu.Opened += ContextMenu_Opened;
            //add something that we can use to get the data grid on context menu events
            contextMenu.ItemClick += ContextMenu_ItemClick;
            contextMenu.Opening += ContextMenu_Opening;
            // set menu Theme
            StyleManager.SetTheme(contextMenu, StyleManager.GetTheme(this));
            RadContextMenu.SetContextMenu(this, contextMenu);

   }
           

}

Hi,

I'm trying to save RadGridView columns order by using Persistance manager:

                PersistenceManager manager = new PersistenceManager();
                manager.AllowCrossVersion = true;
                stream = manager.Save(radGridView);

And

Reading back:

                PersistenceManager manager = new PersistenceManager();
                stream.Position = 0L;
                manager.Load(radGridView, stream);

I change order using drag and drop  and then saving the radgridview.

Sometimes order is right, but many times order is something else that I save.

What is the problem? I sent your simple project that you can verified the problem.

Save button is saving grid on the stream.

Format button is return grid in original order.

Get button is loadin order in the stream.

 Here is to prosess:

1. Start to program.

2. Change column order

3. Press Save button.

4. Load original order.

5. Press Get Button.

Some times order is correct and some times is not.

I use group to show group data,  the group and item both can connec to other control , the design picture is as attach files "split.png"

there are two question

1. I set the template as follows

 <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="telerik:RadDiagramContainerShape">
                        <Border x:Name="ContainerBorder"
                                Width="30"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                CornerRadius="15" />
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style> 

and set the item circle position as follows

 public override bool AddItem(object item)
        {
            var viewModel = item as TransformationNode;
            if (viewModel != null)
            {
                viewModel.Position = new Point(this.Position.X, this.InternalItems.Count * splitTransformationHeight);
                return base.AddItem(item);
            }

            return false;
        }

but the group show as attach files "SplitDiagramGroup.png"   the height is too big,what is the reason

2. I wish the  item circle can not drag alone, when drag the item circle,  the whole  group move too ,   how to realize?

than you 

Dear Team,

If the doc is open for the first time, a new doc window will open and if the same doc is open again, the existing window should be set active. Currently keep opening new windows instead show already opened window. How can i achieve this. please advise.

Thank you.

I have an AutoCompleteBox defined like this:

The ItemSource is set to a List<string>.

I then try something like this but acb_Interviewer.SelectedItem remains null and only the watermark is visible in the control.

 What am I doing wrong?

Hello!

I have a question about the RadContextMenu. I created my class DataGridView this class inherited from RadGridView. Look this:

 public class DataGridView : RadGridView
{

public DataGridView()
{

            // create menu
            var contextMenu = new RadContextMenu();
            RadMenuItem item = new RadMenuItem();
            item.Header = "Hello";
            contextMenu.Items.Add(item);
            contextMenu.Opened += ContextMenu_Opened;
            //add something that we can use to get the data grid on context menu events
            contextMenu.ItemClick += ContextMenu_ItemClick;
            contextMenu.Opening += ContextMenu_Opening;
            // set menu Theme
            StyleManager.SetTheme(contextMenu, StyleManager.GetTheme(this));
            RadContextMenu.SetContextMenu(this, contextMenu);

    }

}
