Hi! All,
I have a dropdown on my aspx page and based on the dropdown value i have to show the number of rows in a gridview, effeciently using sessions & viewstates.
for example:
If I select 4 in dropdown, then it should display only 4 rows in the gridview.

Thanks

well there are two ways to handle this.
1. When ever selection is chnaged, run your db query and return only the number of selection, say only 4. This is the most easiest to handle and less work on the UI side.

2. If you don't want to handle in the db, then in the RowCreated event monitor how many rows are created then made the remaining rows visible property to false.

I believe the first approach is the best one and easier and less maintenance.

Put your grid view bind data code
