Hello Chenna Basappa C,
You can check out the following how-to article from our documentation, that demonstrates resizing of the Grid, when the browser Window is resized.
Adapt it as necessary, replacing the window element with the one, containing your Grid, and adjusting the column properties, e.g.:
, width: 500},
, width: 500}
Please note that each column should have a width value defined.
I hope this helps.
