Hi,

I have one requirement, the datasource of the ultragrid has too many rows. When load in once, it will take much time and the client area of the grid has a scroll bar. I want to add the load on demand feature to the grid and then I need to do two thing:

1) get the maximum rows that the grid's client area could host.

2) get the maximum rows count + 1of row and add it to the data source. then the grid have a scroll bar.

3) when user click the scroll down button in the scroll bar.get another maximum row + 1 of rows and then set the data source.

I have two problems:

1 how get the maximum row count that the grid client area could host.

2 how handle the scroll event in the ultragrid.

Please help.

thanks,

Eric
