Hi,

I tried this out and I get the same results. The Autosizing appears to be using the Format of the entire column, but ignoring the format on a cell when provided by an editor. This seems to be a bug. I'm going to ask Infragistics Developer Support so create a case for you and write this up for developer review so we can get it fixed.

One thing you could do in the mean time is apply a format to the column. This isn't perfect, but if you use the longest of your three possible formats, it should produce better results than what you have now - which is that the column is way too wide.

Note: ignore the set width lines in the initialize code, that was just added after the failed autosizing.

it should be

if (col.Key == "Format")
                            {
                                col.Hidden = true;
                            }
                            else if (col.DataType.Name == "Decimal")
                            {
                               
                                col.Editor = new EditorWithText(owner);
                               

                            }
                                
                            col.PerformAutoResize(PerformAutoSizeType.AllRowsInBand);

I am using this method to format various rows in a column differently.  It works except for one thing:  PerformAutoResize does not work, it resizes the column as if there was no formatting.   Note, I am ignoring your line "DefaultEditorOwnerSettings settings = new DefaultEditorOwnerSettings();" since the settings variable is not used.

Below is my code:

private void ugResults_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            try
            {
                int DefaultWidth = 100;
                MyDefaultEditorOwner owner = new MyDefaultEditorOwner();
                if (e.Layout.Bands[0].Columns.Exists("Format"))
                {
                  
                        foreach (Infragistics.Win.UltraWinGrid.UltraGridColumn col in e.Layout.Bands[0].Columns)
                        {
                          
                            if (col.Key == "Format")
                            {
                                col.Hidden = true;
                            }
                            else if (col.DataType.Name == "Decimal")
                            {
                                //row.Cells[col.Index].Editor = new EditorWithText(owner);
                                col.Editor = new EditorWithText(owner);
                                col.Width = DefaultWidth;

                            }
                                
                            col.PerformAutoResize(PerformAutoSizeType.AllRowsInBand);
                                
                                
                        }
                }
                
            }
            catch (Exception ex)
            {
                _mainform.HandleException(ex);
            }
        }

    }



    public class MyDefaultEditorOwner : DefaultEditorOwner
    {
        public override void GetFormatInfo(object ownerContext, out string format, out IFormatProvider provider)
        {
            format = "";
            provider = null;
            try
            {
                CellUIElement cellElement = ownerContext as CellUIElement;
                if (cellElement.IsNull() == false)
                {
                    UltraGridColumn column = cellElement.Column;

                    UltraGridRow row = cellElement.Row;

                    switch (row.Cells["Format"].Value.ToString())
                    {
                        case "Money":
                            format = "#,##0";
                            break;
                        case "Decimal":
                            format = "#,##0.0000";
                            break;
                        case "Percent":
                            format = "0.00%";
                            break;
                        default:
                            format = "";
                            break;
                    }
                }
                else
                {
                    format = "";
                }

            }
            catch (Exception)
            {

                //eat
            }



        }
    }
