WinForms DataGrid data display limit

[Rakesh Rajan]

Hi, Is there a limit to the number of rows (amount of data) a datagrid can display in a datagrid? Is there any internal optimization in the datagrid which fetches data from the dataset only for those rows which are visible to the user? ( I saw someone say so in a NG) Is there a limit similarly for datasets? ( I have read now and again it's only limited by the client's systems' memory...but wanted to make sure :) ) I am concerned since i need to display ALL the data (around 10K records). Thanks Rakesh

This gets or sets the maximum amount of memory allowed in memory for the given Process.

Not yet, at least in the .NET base class library. In .NET 2.0 they have introduced several new control classes, including a GridView[^] which supports virtual lists, which is to what you're referring. There's nothing from stopping you now (there was a good article a LONG time ago about how to do this even in DHTML), but the burden is on you unless you want to buy a commercial solution like a couple from ComponentOne[^].
