Hello, I get the same error below when trying the sample. Any luck getting this sample to work?

'CustomClientAnimation' does not contain a definition for 'UltraWebGrid1' and no extension method 'UltraWebGrid1' accepting a first argument of type 'CustomClientAnimation' could be found (are you missing a using directive or an assembly reference?)

I am new to Drag and Drop, does anyone have a good example of Drag and Drop between two UltraWebGrids?

I can not get your download to work... it keeps giving me the error below:

Could you post the java script for moving the rows and resorting them? I have a similar problem.
