Hi, thanks for the swift response.
The data grid issue didn't present itself when I created it by hand with fake '00000' values, but when I pasted a larger set of data (only 5663 bytes) it has remained laggy. I think it is hard to separate the graphical engine from this, and I wonder if such a small amount of supported data for a control could be causing this.
re: control being locked on the edge - the resultant data grid went off screen, and at some point I was not able to move it. After reducing its size, I can now move it.
I will send the bmpr file and the source excel sheet I used.
As you have provided a generic support address, do I need a case reference or a name to help route this?
Also I should add - whilst moving the control (via mouse or even by selecting and using the arrow keys) the CPU usage goes to 50% and it took minutes for 10-20 presses of the left arrow key to complete!
thanks for the anigif - project details was hidden and the sketch mode was indeed not selected!
as for meeting my needs: Balsamic supports the functions I require, but they are not working as designed/intended.. I am using a tiny fraction of the complete functionality and I have issues with only 1 supported feature within my wireframe - your solution supports much more than this, and I will need to create entire sets of mockups soon..
