dhtmlgrid with data from HTML table

Hi,

I am using DHX grid for an application. The data comes from HTML table. I have two questions.

(a) Is it possible to freeze the header row while user can scroll the data?

(b) I have an onEditCell event attached to the grid. When I enter a value inside the editable column, I can update the other read-only columns based on the entered value - works fine. But the value entered disappears from the editable column. If I remove the onEditCell event, I can see the value entered in the editable cell remains ok. I even tried to use innerHTML construct to set the value - doesn't work. Any idea how I can resolve this?

Thanks
Shekar

This is default behavior, but you need to specify height of grid, add gridHeight attribute to the table tag

<table gridHeight="500"...


>>But the value entered disappears from the editable column. 
Be sure that event handler has 
     return true;
at the end, in other case it will be counted as command to deny result of edit operation. 

You guys are the best.
It worked. Thanks a lot.
