Mark cell that isn't loaded on grid


My problem is:

I need to mark one cell that isn’t loaded on gridview.


On the grid only has loaded 100 registers.

mygrid.mark(99,2); works succesfull, but if i use mygrid.mark(101,2); following javascript:error appears Uncaught TypeError: Cannot read property ‘_childIndexes’ of null

How can I solve this problem? I need to reload the grid?


Is cell not loaded or not rendered?
If you are using dyn. loading and data is really not loaded on the client side yet - you can’t mark such cell.

If data is loaded , but just not rendered yet, you can try to use

grid.getRowById(101); grid.mart(101,2);
