Can anyone tell me more about the drag and drop feature with the grid? I have a simple grid that i want to be able to reorder the items, and once the items are in correct order i can use a button to loop through and retrieve that order. So far i can only select on a row but when i move the row it goes back to it's original order.
Thanks
Thanks

Yes, I have already looked at those. The problem is that in your examples you're using ILists which works fine for your demos because you're not committing any changes to your data. Is there anything out there when you're binding to DataSet and need to bind the order back to the database?

Hi Mike,
In order to reorder data in the DB you should store the records' order in the backend. For example, by adding a new column to the database table. Then when the order is changed, you should update this column. Please find attached a simple implementation representing the aforementioned approach.

Hi,
This demo does not seem to work, the list does not change and the database remains unchanged?
I have plugged it into my project using the Q2 release of RadGrid.
Any ideas?
Tony.

Okay, sorry - it does work, but inconsistently. I especially cannot get the first line to reorder on first page load and it seems limited that you cannot drop a row at the bottom of the grid?

Hi Tony Hogben,
You can use the DropPosition property of the RowDrop event's argument object in order to determine if the dragged item should be placed before or after the destination item. And modify the update statement accordingly. You may refer to this Code Library for a possible implementation.
