Your message about "it says TextBox is not property of DataGridColumnStyle" isn't actual now, I think. But "it did not work" is. Yes. The case is more complicated ... DataGrid uses TextBox only if your cell is current. If no - it simply displays the cell. So, You must override displaying cells in DataGridTextBoxColumn. Inherit from this, next override PaintText methods: Draws the text and rectangle at the given location with the specified alignment. protected void PaintText(Graphics, Rectangle, string, bool); protected void PaintText(Graphics, Rectangle, string, Brush, Brush, bool); See System.Drawing namespace.

Manually set table style for datagrid and appriopriate column styles. Set Multiline and WordWrap properties of their textboxes. Not tested. Example from VS help: DataGridTableStyle ts1 = new DataGridTableStyle(); ts1.MappingName = "myTableName"; DataGridColumnStyle tc1 = new DataGridTextBoxColumn(); tc1.MappingName = "myColumnName"; tc1.HeaderText = "Column Name"; tc1.Width = 250; ts1.GridColumnStyles.Add(tc1); myDataGrid.TableStyles.Add(ts1); // after creating TexBox tc1.TextBox.Multiline=true; tc1.TextBox.WordWrap=true;
