hi,

check this ex when you select any rows on the 1st grid and click the button on toolbar defined,seleted data will be displayed on the 2nd grid.

similary instead of button click you can double click on the row of ist grid, and that will be displayed in the 2nd grid.

for this u have to use Double_click event,u have the code for that also in the below given example with commented lines.
