ASPxGridView very slow with 30 properties

Hello Torsten,
I have tested the ASPxGridView with the mentioned count of rows and columns, and found that the size of the generated HTML code is very big. This causes a significant delay, especially in IE. The main cause is that the ASPxGridView is rendered via HTML tables, and I am afraid that is it impossible to change this behavior. However, you can significantly decrease the size of the generated HTML, and thus improve performance, after removing the default DataItemTemplate from data columns using the following ViewController:

C#
public class ViewController1 : ViewController {  
    public ViewController1() {  
        TargetViewType = ViewType.ListView;  
    }  
    protected override void OnViewControlsCreated() {  
        base.OnViewControlsCreated();  
        ASPxGridListEditor editor = ((ListView)View).Editor as ASPxGridListEditor;  
        if (editor != null) {  
            foreach (GridViewColumn column in editor.Grid.Columns) {  
                if (column is GridViewDataColumn && !(column is GridViewDataActionColumn)) {  
                    ((GridViewDataColumn)column).DataItemTemplate = null;  
                }  
            }  
        }  
    }  
}  

Please let me know if you need any further help.
Thanks,
Anatol
