Adding rows quickly

[Bob]

I want to add 1000 rows to a RadGrid that has 8 columns quickly, and I want the user to see them added real-time.

Currently I'm able to add about 10/second...is that the quickest it can be?

Thanks.

Also, when this is processing (and also later when I update rows) the form itself flickers...suggestions for that as well?

Hello Bob,

Thank you for this question.

You can speed up the process of adding rows by suspending the update operations to be performed on the grid. This approach is illustrated in the code snippet below:

this.radGridView1.GridElement.BeginUpdate();
this.radGridView1.Rows.Add(1, "John Smith", 3.45);
this.radGridView1.Rows.Add(2, "Peter Jackson", 9.12);
this.radGridView1.Rows.Add(3, "Laura Ashley", 11.11);
this.radGridView1.GridElement.EndUpdate();

I hope this helps. Do not hesitate to contact me if you have other questions.

Thanks - I was already using this but I realized it was in the wrong place.  I moved it outside of my loop, and that doubled the rate to about 20/second.

Thanks.
