Hi , i have a radgrid populated with a dataset:
Dataset.DS.PianificazioneDataTable dt = new Dataset.DS.PianificazioneDataTable();
  
row["Base"] = item.OFATH;
dt.Rows.Add(row);
  
rgvPianificazione.DataSource = dt;

now when i scroll down the grid, it takes 1/2 seconds to load the next row ( i have many columns...)
is it possible, to load the entire dataset, so the scroll should be immediately

thank in advantage

Hello Matteo,

The RadGridView uses UI Virtualization which means that whilst your data is loaded, it only creates the objects for the visible items. This aids performance. However, there were may further performance improvements, including some to scrolling in the latest Q1 2011 release of the RadGridView, and indeed all of the controls.

I'd suggest upgrading to the latest version to take advantage of this and may other improvements and new controls.
Hope that helps
Richard
