Hi,
I am using XamDataGrid in my project, My Database having almost 7,50,000+ records.
Their are 8-10 Coloum from Table and we need to Bind this Table to XamDataGrid.
We dont require Paging, but can we do paging using scroll position and get only those records from database with current scroll position.
Is their any event to handle such type of scenario.
so we can load record to grid by paging(like cursors in record ADO ) using scroll or by any other technique.
Please help out me for this Problem.
If possible provide sample code.
Thanks.

Hi
I'm implementing the same virtualization technique like danieljant but the grid fetches the record still all at once. I've set ScrollingMode already to Deferred and besides that everthing is set defaultwise.
danieljant said: I think, this has something to do with the scrolling-feature. But i thougt by setting scrollingMode to deferred, this feature is disabled and the grid has no need to access elements in between.

Me again :-)
To give you some more background. What i really wanna do, is display datalists retrieved from a webservice in your grid.
I have two WebMethods like this:
int GetDataCount()andList<Item> GetData(int start, in count)
Count can be very high.
And i want a performant way to display the data in your grid. My solution with the custom collection implementing paging and caching methods is just a try.
Maybe you have another, a better solution.
