How to target BeginInsert to detail level of hierarchy?

I have a master/detail hierarchy implementation (see attached picture).

I have coded to RowLoaded event to set GridViewRow.IsExpandable = false for master rows whose detail collection is empty. I wanted to visually show that there were no associated details, and save the user from clicking on the (+) expander control needlessly. I have set ShowInsertRow="True", and my preference is to keep ShowInsertRow="False". Instead, I would like to have a button (elsewhere in the UI) to call the BeginInsert() method. However, how do I target the detail level - particularly if the master row has an empty detail collection?

Nested grid view's context menu

Hi!

I have a grid which has another grid in its row details. Both grids should have a context menu, however, if I right-click in the row details grid, it shows me the context menu of the parent grid. Is there a way to have it show the child grid's context menu when right-clicking on the child?

ToCsv and column headers

Hi,

I'm using the ToCsv method on the grid view. Some of my headers in that grid are TextBlock's (so that I can add a tooltip), i.e:

<Controls:GridViewDataColumn.Header>

<TextBlock ToolTip="Product Quantity">Prod Qty</TextBlock>

</Controls:GridViewDataColumn.Header>

However, when in the CSV text, the column shows up as "System.Windows.Controls.TextBlock" as I guess it's just doing a ToString on whatever the column header is. Is there a way to change what is used by ToCsv to name headers?

Few questions about IsLoadOnDemandEnabled

First question:

Is it possible to have IsLoadOnDemand = true but NOT show the arrows on some items? (The arrows that indicate the items have items themselves). Not all our items have children, so we don't want to show the arrows in all of the items.

http://www.screencast.com/users/CarloToribio/folders/Jing/media/abe8d5f6-a1f0-4776-9812-b709f3ff4c97

Second question:

How can I make the items show the loading animation while I'm doing something in the LoadOnDemand event? We're trying to deserialize some objects in there, and it might take a second or two, but the animation doesn't show up, it just freezes for those two seconds. I tried it this way but no luck:

private void treeView_LoadOnDemand(object sender, RadRoutedEventArgs e)

{

RadTreeViewItem clickedItem = e.Source as RadTreeViewItem;

clickedItem.Dispatcher.BeginInvoke(new ThreadStart(delegate

{

clickedItem.Items.Add(new RadTreeViewItem() { Header = clickedItem.Header + "." + (clickedItem.Items.Count + 1) });

Thread.Sleep(2000);

}));

}

Any suggestions?

Thanks.

Thanks.
