Using a custom itemrenderer in datagrid to update value in the same row but different column/cell

Question

Here's what I have so far.  I have one datagrid (dg1) with enable drag and another datagrid (dg2) with dropenabled.  Column3 (col3) of dg2 also has a custom intemrenderer that's just a hslider.
When an item from dg1 is dropped on dg2, a custom popup appears that asks you to use the slider in the popup to set a stress level.  Click ok and dg2 is populated with dg1's item as well as the value you selected from the popup window.  I was also setting a sliderTemp variable that was bound to the itemrender slider to set it but that's obviously causing issues as well where all the itemrenderer sliders will change to the latest value and I don't want that.
What is needed from this setup is when you click ok from the popup window, the value you choose from the slider goes into dg2 (that's working) AND the intemrenderer slider needs to be set to that value as well.  Then, if you used the intemrenderer slider you can change the numeric value in the adjacent column (col2).   I just dont know how to hook up the itemrenderer slider to correspond with that numeric value (thatds be in col2 on that row);

Answer 1
