Scroll Bar BUG found in Grid
Hi all,
I have just found a bug in Grid's Scroll component. It looks above code working correct accept Scroll realted bug of the grid.
If you were try the code you see that problem arises after
alert( strVars ); line, which is at the end of ExpandRow() method.
Scroll bar goes top when we clicked on below rows..

This example shows a grid inserted within a grid. It also illustrates how to expand a row when the plus is clicked. Note that the inserted grid (grid2) is used repeatedly so only 1 row can be expanded at a time. You also could replace grid2 with another AW object such as radio buttons or checkboxes. <b>There are a few bugs in the scrollbar code. The inserted grid seems to inherit scrollbar properties from the main grid.</b>
