Drag/Drop - Need to have "Drop in" behavior always

Hi,

We have implemented drag-drop feature for the trees in our application - when we are dropping to destination tree node it shows "Drop after <destination-node>", "Drop before <destination-node>" and "Drop in <destination-node>" message - but we need that it always behaves like Drop in meaning if user is dropping in any node in between child-nodes of any parent node - the message should not read "Drop before <destination-node>" or "Drop after <destination-node>" instead it should read "Drop in <parent-node>"

For example - if we have a parent node say P and there are child node say C1,C2,C3,C4 and now if we are dropping any node between C2 and C3 - it will say either "Drop before C3" or "Drop after C2" - but instead we want to show "Drop in P". We tried using TextDropAfter and TextDropBefore property - but this can only set the message to "Drop in" and thus "Drop before <destination-node>" and "Drop after <destination-node>" will read "Drop in <destination-node>" but we intend to show "Drop in <parent-node>".

Please let know how to achieve this.

Thanks,
Bala

Does RadGridView have a virtual mode?

I've built a WPF application which uses the RadGridView control on a number of different windows. The point of these windows is to query the database for data and display the results.

As this is a WPF application and not a Web application, we feel that the application should not page the data, which can change in the background while the user is viewing a page of data. Ideally, the control should work in the following manner for very large data sets (above 100,000 rows):

1. The control retrieves the IDs of all and all matching rows from the database and caches them.

2. Using the cached IDs, the control retrieves a reasonably sized subset of the data to display for the user, say 1,000 rows.

3. If the user scrolls to an area of the result set where the data has not yet been retrieved, the control retrieves more data, again a resasonable sized subset.

Working in this manner prevents the program from using huge amounts of memory and time, as it would if the program just retrieved all of the data at once.

Is there a way to implement this type of functionality with the RadGridView control?

Thanks

Tony

Binding IsSelected with virtualization

Hi,

I've bound my model's IsSelected property to the TreeListViewRow's IsSelected property. The problem is that if I have a long list of items, the user can select the first, then scroll down to the bottom and Shift+Click the last to select them all. But only some of my model objects get their IsSelected flag set. It's mostly just the model objects that are visible. I suspect the problem is caused by virtualization being turned on. There's no TreeListViewRow for most of the items, so their IsSelected flags don't get set.

So how do I get my IsSelected flag set for virtualized rows?

My current binding is:

<Style TargetType="{x:Type telerik:TreeListViewRow">

<Setter Property="IsSelected" Value="{Binding Path=IsSelected, Mode=TwoWay}"/>

</Style>

Thanks,
Bob

Focus on RadMap on load and Mouse Wheel

Hi,

I have a requirement to have the focus on RadMap when the form is loaded.I tried both:

FocusManager.FocusedElement="{Binding ElementName=radMap1}"

and

private void UserControl_Loaded(object sender, RoutedEventArgs e)

{

radMap1.Focusable = true;

radMap1.Focus();

}

But with no luck.I need to use the mouse wheel to move to different areas in the map.This is not working until i click once on the map.The reason i want to avoid clicking on the map is that I am drawing a MapPolygon by combining each click point on the map.

Thanks in advance.
