Grid distortion after sorting on any column

Hi,

I am facing a strange issue with sorting.
I have created a grid with a dropdown option to select the number of rows to be displayed on the grid like 10,20,50,100

When i change the number of rows to display everything works fine, grid is rendering properly.
But once i perform a sort on any column and change the number of rows to display from 10 to 20 only the 10 rows are getting displayed, the rest 10 rows are getting blank. And after that if i do any change on the number of rows to display grid, it does not render properly also the selection mode for grid goes off.

please help me regarding this.

thanks

Looks like you need to clear rowIndices array - try clearRowModel() method.

Thanks alex,
clearRowModel() resolved the issue
