I am trying to use the Grid Control to render a dataset which contains about 45 columns and 80 - 100 rows. I notice that while the data itself takes less than 1/2 a second, it looks like the Grid control is taking about 60 - 90 seconds (and I am talking about a single user - two or more users and users experience timeouts) to process on the Serverside and then about a minute to render on the browser. After the grid is rendered, both vertical and horizontal scrolling is not smooth with a noticeable lag. Are there any guidelines on the maximum number of columns and rows for the grid? Has any one else noticed any performance issues with large number of rows and columns?
