Hi, 

Using InitializeLayout is a good idea, since it fires after you set the grid's DataSource. 

But yes, you COULD use the same code in the Form_Load. The only thing you would have to change is where you get the layout from: 

UltraGridLayout layout = this.ultraGrid1.DisplayLayout;

You would, of course, have to do this AFTER you have set the grid's DataSource - otherwise the columns would not yet exist. 

Heloo... 

can i use this code when form load ?

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            UltraGridBand band = layout.Bands[0];
            UltraGridOverride ov = layout.Override;

            layout.AutoFitStyle = AutoFitStyle.ResizeAllColumns;
            foreach (UltraGridColumn column in band.Columns)
            {
                if (column.Key != "String 1")
                {
                    column.MinWidth = column.MaxWidth = column.Width;
                }
            }
        }

I discovered what I am missing: DisplayLayout.Bands[0].Columns["name"].RowLayoutColumnInfo.WeightX = 1.0F for all columns I want to be resized (with optional different weights!)

i have a checkbox column that I do not want to participate in resizing. In the designer I set Width, MinWidth and MaxWidth to 50.   I have set AutoSizeMode to None and LockedWidth to true. (DisplayLoayout.AutoFitStyule is set to ResizeAllColumns) All to no avail . The column is still resized when I send  DisplayLayout.PerformAutoResizeColumns(false, PerformAutoSizeType.VisibleRows) ALL columns are resized! What am I missing?
