Hi, I am having a problem with the grid redrawing itself everytime I hide a row. I need to hide a group of rows together and want the grid to be redrawn only once I have finished hiding rows. I have tried using the BeginUpdate/EndUpdate calls on the grid but they result in the grid being redrawn each time a row is hidden. Does anybody have any ideas about what I could do? Thanks

Did you try code like this? It seems to work OK for me.
private void button1_Click(object sender, System.EventArgs e)
{
	this.gridDataBoundGrid1.BeginUpdate();
	for(int i = 1; i < this.gridDataBoundGrid1.Model.RowCount; i = i + 2)
	{
		this.gridDataBoundGrid1.Model.Rows.Hidden[i] = true;
	}
	this.gridDataBoundGrid1.EndUpdate();
	this.gridDataBoundGrid1.Refresh();
}
