Hi

When the SelectionMode of the grid is set to Extended, you can select multiple rows by dragging the mouse over many rows.

Is it possible to turn this off (but leave extended selection on)? My problem is that I want multiple selection (via Ctrl and Shift keys) but also want to use drag and drop, When I start the drag the grid will often start to select more rows as the mouse moves over them even though a drag is in progress. This only seems to happen some times, e.g. If you click on a row and drag without releasing the mouse button then this problem occurs, but if you select a row, release the mouse button, then click and drag the same row, it does not.

Thanks
Russell Mason

Hi Russell Mason,

We have plans to introduce new API that will allow you to turn the drag selection on/off. We will try to introduce the API as soon as possible - probably right after the SP2 which due this week.

Has there been any movement on this issue?

We have the same problem with drag selection interfering with drag and drop. It is especially annoying in our case because one grid is located directly below the other. Almost every drag and drop will inadvertently select additional grid rows. 

Thanks,
Ryan

Hi Ryan Moore,

We have raised the priority of this issue and we will allow drag selection to be disabled when we introduce our Q2 release.

Hi Ievgen,

Unfortunately the improvements that would allow you to disable our drag selection mechanism did not make it into the official release but we will soon push them with one of our Internal Build. Most probably we will introduce the improvements with the internal build that is scheduled for next Friday.

Sorry for the inconvenience. 


All the best,

Hello Daniel Walton,

Yes, it did make it into the build. The property is called DragElementAction. Setting is to none will disable our drag selection mechanism.
