[Solved] Drag&Drop file from desktop on RadGridView

[Andreas]

Hi,

I want to drag a file from the desktop onto a RadGridView and then upload it when it is dropped on certain grid row. By setting AllowDrop=True I managed to react on the Drop event of the RadGridView. But now I am stuck. I tried to get the dropped File by using

private void gridDocuments_Drop(object sender, DragEventArgs e)
{
  FileInfo file = e.Data.GetData(typeof(FileInfo)) as FileInfo;
}

but I get a NotImplementedException.

So could please someone help me with the following questions:
1) how can I start the upload e.g. with a RadUpload?
2) I want that the row over which the mouse holds the currently dragged item to be highlighted. Do I have to implement this on my own or is there a way to force RadGridView to do so?

Thanks in advance and best regards,
Stefan

Hello,

I found an answer to my first question in the following thread:
http://www.telerik.com/community/forums/silverlight/richtextbox/moving-image.aspx.

Still I would appreciate an answer to my second question. Does anybody know, how a row of a RadGridView is highlighted but not selected on DragEnter and set back to normal on DragLeave? I would like to have the same behaviour for DragOver as for MouseOver.

Thanks for your help,
Stefan

Hello Stefan,

You can highlight the  desired row using the IsMouseOver property. To force the row to update its state OnApplyTemplate call is required.

row.IsMouseOver = true;

row.OnApplyTemplate();

Currently, we are working to improve this, so that no additional calls are required. Please, give it a try and let me know if you have further questions.
