Hi,

What version of the grid are you using?

And in the code you have here, what is "this"? Is this an inherited grid control, or is this the form?

I don't see anything wrong with this code, so my best guess is that doing this in InitializeLayout is too early.

It's also not very efficient to loop through all of the rows in the grid, anyway. You might be better off calling PerformAutoSize in the InitializeRow event, or if you must loop, do it immediately after setting the DataSource/DataMember on the grid instead of inside InitializeLayout.

The MultiLine display works after editing the cells but not before, even by the 3 events i use.

If you dont have time to open this file, here is the main code :

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            string[] test = new string[2];
            test[0] = "test";
            test[1] = "testtt eeee eeeeee eeeee ee";
            this.ultraDataSource1.Rows.Add(true, test);
           
        }

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            this.ultraGrid1.SuspendLayout();
            this.ultraGrid1.BeginUpdate();

            this.ultraGrid1.DisplayLayout.Override.CellMultiLine = DefaultableBoolean.True;

            foreach (UltraGridCell cell in this.ultraGrid1.DisplayLayout.Rows[0].Cells)
                cell.CellDisplayStyle = CellDisplayStyle.FullEditorDisplay;

            this.ultraGrid1.DisplayLayout.Bands[0].RowLayoutStyle = RowLayoutStyle.ColumnLayout;
            e.Layout.Override.RowSizing = RowSizing.Free;

            foreach (UltraGridColumn column in e.Layout.Bands[0].Columns)
                column.AutoSizeEdit = Infragistics.Win.DefaultableBoolean.True;

            foreach (UltraGridRow row in e.Layout.Rows.All)
            {
                // For the PerformAutoSize() to works, you need to uncomments those 2.
                //row.PerformAutoSize();
                row.PerformAutoSize();
            }

            this.ultraGrid1.EndUpdate();
            this.ultraGrid1.ResumeLayout();
        }


        private void ultraGrid1_AfterColPosChanged(object sender, AfterColPosChangedEventArgs e)
        {
            foreach (UltraGridRow row in this.ultraGrid1.Rows.All)
            {
                //This line doesn't work.
                row.PerformAutoSize();
            }
        }

        private void ultraGrid1_InitializeRow(object sender, InitializeRowEventArgs e)
        {
            //This line doesnt work. Adding more PerformAutoSize() won't work either.
            e.Row.PerformAutoSize();
        }
    }

I dont get my multiline, is the RowLayoutStyle needed in InitializeRow??

As a general rule, the RowLayoutStyle, or any property that applies to a column, band, or override should be applied in InitializeLayout.

Properties that affect individual rows or cells are better set in the InitializeRow event.

It is similar to what is inside the documentation. Why not working? And here is the code :

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            this.ultraGrid1.SuspendLayout();
            this.ultraGrid1.BeginUpdate();

            this.ultraGrid1.DisplayLayout.Override.CellMultiLine = DefaultableBoolean.True;
            this.ultraGrid1.DisplayLayout.Bands[0].RowLayoutStyle = RowLayoutStyle.ColumnLayout;
            e.Layout.Override.RowSizing = RowSizing.Free;


            this.ultraGrid1.EndUpdate();
            this.ultraGrid1.ResumeLayout();
        }


        private void ultraGrid1_AfterColPosChanged(object sender, AfterColPosChangedEventArgs e)
        {
            foreach (UltraGridRow row in this.ultraGrid1.Rows.All)
            {
                //This line doesnt work.
                row.PerformAutoSize();
            }
        }

        private void ultraGrid1_InitializeRow(object sender, InitializeRowEventArgs e)
        {
            //This line doesnt work.
            e.Row.PerformAutoSize();
        }
    }

I tried replacing the code in your sample with this code, and now I see the same problem without accessing the cells. This seems like a bug to me, so I am going to send the modified sample over to Infragistics Developer Support so they can write this up for developer review and get it looked into.
