Yeah, that didn’t work reliably for me either. I ended up just using the load event instead, works fine for my purposes.
private void MainController_Load(object sender, EventArgs args)
{
Ice.Lib.Customization.PersonalizeCustomizeManager personalizeCustomizeManager = this.csm.PersonalizeCustomizeManager;
// myGrid
Ice.Lib.Framework.EpiUltraGrid local2 = ((Ice.Lib.Framework.EpiUltraGrid)(personalizeCustomizeManager.ControlsHT["a982c660-8da7-4c1a-a775-624d31758cb5"]));
local2.DisplayLayout.Override.RowSizing = Infragistics.Win.UltraWinGrid.RowSizing.AutoFree;
local2.DisplayLayout.Override.CellMultiLine = Infragistics.Win.DefaultableBoolean.True;
}
