calculateDropIndex should tell you where it is getting inserted, then you can get surrounding data and fix it up.

The data in the DataGrid is sorted on several different fields. What I'd like to do is to enable the user to rearrange the rows in the DataGrid via dragging and have part of the data update itself to how the user arranged the rows (so then I can write the data back to the database). For instance: rowOne A a 1 rowTwo A a 2 rowThree A a 3 rowFour A a 4 rowFive A b 1 rowSix A b 2 rowSeven A b 3 rowEight A b 4 If the user drags rowOne below rowThree, I'd like the underlying data to be rewritten to: rowTwo A a 1 rowThree A a 2 rowOne A a 3 rowFour A a 4 rowFive A b 1 rowSix A b 2 rowSeven A b 3 rowEight A b 4 But if they were to drag it past rowFour it would look like: rowTwo A a 1 rowThree A a 2 rowFour A a 3 rowOne A a 4 rowFive A b 1 rowSix A b 2 rowSeven A b 3 rowEight A b 4 I know some of this I can accomplish with the sort fields. But how do I get to the part where I rewrite the last field in the data based on the location of where the user drops the row? Can the function that gets called when the row is dropped see which rows are above and below it? Or am I better off dropping the last field from my sort, then loop over the data when the row is dropped, writing the row index to that column? Any suggestions or shoves in the right direction are greatly appreciated. -- Howard Fore, [EMAIL PROTECTED]<mailto:[EMAIL PROTECTED]> "The universe tends toward maximum irony.
