RadGridView Reorder rows

[troy]

Your example for the Reorder rows is very good with the exception that I can't show the DropPreviewLine.  In the silverlight documentation it shows an example for it with the preview line, but neither the silverlight or WPF demo example have the preview line.  I am hoping that you have a WPF example that will show the preview line as well.

Thanks!

Hello Troy,

You may refer to this blog post. It illustrates a project that implements row reordering in RadGridView and displays a drop position indicator. Please, let me know whether this approach, meets your requirements.

I was looking for something more in line with how the tree view drop indicator looks since I am using drag and drop in both the tree view and grid view.  I would prefer they be consistent.  This is a link to a silverlight example in the help document:

Thanks!

Hi Troy,

 I have prepared sample application, that provide same functionality as the one in the Silverlight article mentioned. Please, have a look at the attachment and let us know if you have any further questions.

This is exactly what I was looking for.  Thank you very much!

Has this solution been updated using the new (non deprecated) drag drop manager? Or is there a more current method of handling this? Thanks.

Hello Andrew,

A more up to date implementation of the demo you can look into the RowReorder WPF / Silverlight example. In addition, you can check the DragDropManager documentation for more details on how to use it.

I hope this helps.

Boris, thanks for the update! One question though, in the deprecated WPF example, it shows a nice line as a drop position feedback tool instead of this weird tooltip debug message. 

 

Is this behavior (having a nice line between the rows where you will drop the dragged item) still possible in the current iteration of telerik's (silverlight) radgridview? 

 

Radtreeview does it natively without much hassle, and I very much prefer the clean drop line over the tooltip with text. 

 

Thanks

Hello Thijs,

I believe the Drag and Drop Within RadGridView demo from our SDK Samples Browser  the desired behavior. Of course, you are free to modify that to suit your requirements.

Could you please have a look at it and let me know if it works for you?

Dear Dilyan, 

Thank you for your answer. Unfortunately that example also uses the descriptive tooltip "Dragging Item before/after rowitem" instead of a "droppreviewline" 

 

To clarify please see the two attached files from your demo site. 

The behavior I'd like to enable or implement is the IsDropPreviewLineEnabled functionality, but on a gridview. 

 

So to just have a thin colored line to show the position where the item will inserted after a drop instead of a tooltip describing where it will drop. 

So, of these 2 screenshots, the one shown in "RadTreeView_TreeViewDragAndDrop_060" is the one I want.. 

 

But then on a radgridview instead of a treeview. 

 

Any idea if at all possible?

Hello Thijs,

This is indeed possible, using the aforementioned SDK example. The only modification you need to make is to remove the following lines from the OnDragInitialize method of the RowReorderBehavior:

e.DragVisual = new DragVisual()
{
    Content = details,
    ContentTemplate = this.AssociatedObject.Resources["DraggedItemTemplate"] as DataTemplate
};

You could also modify the drop position feedback presenter in the CreateDefaultDropPositionFeedback method and change the created Ellipse's Fill color to White to exactly match the RadTreeView implementation.

I hope this produces the desired behavior.
