Is your query returning 100,000 rows or is that just the table size?

Solution 1

The user never wants to see 100,000 rows of data at a time. The control you're using can be used in a virtual mode. In this way, you will fetch only the data which could be visible on one screen, ideally, 3 or so times more. If a user wants to look at previous/next page, it will be a situation of cache hit, so the result will be rendered almost immediately. In worst cases, the user wants to scroll far away; and it will be a total cache miss, but re-fetching of full data will not take too long time as this is just another 3+ screens of data. You can devise more sophisticated caching mechanism, but the idea will be pretty much the same, http://en.wikipedia.org/wiki/Cache[^].

The control you're using can be used in a virtual mode....I didn't get this line..can you explain little bit..

It's a bit complicated, need some work on your side. DataGridView and ListView have virtual mode. In this mode, you don't populate it with data -- they present data supplied on request, depending on user's action. For example, is a user scrolls a virtual DataGridView, is request data for the rows which should scroll into view. You supply data in event handles. Data binding does that automatically.

Solution 2

It's horrible man that loading 100,000 rows at a time. Just think about the end user, they never like that much delay or something.

Just use paging, filtering in data.

In database side
SQL Server 2005 Paging Results[^]

In your controls
GridView Multiple Filter AJAX Control[^]
Repeater with Paging and Sorting Features[^]
