>Hi everybody.
>I have two forms with one grid on each form. For both the grids, the parent grid class is same. When I run the application, grid on one specific form becomes very slow. It takes some time to go to the next row (using arrow keys). In other form, control moves very fast from one row to another. Surprisingly, data validation before changing the row is much more for the grid on which the movement is faster.

Is the validation on the slow grid cycling more than once - double or triple validation. Set step on in the slow grid's validation to make sure it's not "repeating itself".

Try to avaiod the validation check if the value has not changed. One way to do this would be to assign the value to the controls tage. AT validation time, if the tag and value are same - do not validate.
