i create this class

 TextCellCustomEditor : TextBox, ICellEditor
   base.MaxLength = 20;
  //some code

and after i create column

 TextCellStyle myTextCell = new TextCellStyle();
 myTextCell.CustomEditorType = typeof(TextCellCustomEditor);
 myTextCell.TextAlignment = ContentAlignment.MiddleLeft;

 myColumns[0] = new Column();
 myColumns[0].DataPropertyName = "1";
 myColumns[0].Visible = true;
 myColumns[0].CellType = typeof(TextCell);
 myColumns[0].CellStyles.AddRange(new Elegant.Ui.Grid.CellStyle[] { myTextCell });
 myColumns[0].HeaderText = "Text cells";

it’s work ok but i need change  MaxLength programmatically. How i can do it?

How i can change this variable when i create column and how i can change this variable in runtime?

MaxLenght is not the width of column but total of characters that it can import the user. For TextBox.MaxLenght = the 10 user can put only 10 characters in the field. This I want to achieve.

Each time your custom editor is activated you can set MaxLength to a specified value.

Please use the Column.Width property. Alternatively you can use the Column.MinimumWidth to make sure that column won’t become smaller in auto-size mode.

i want that each column to have its own maxlength. i need to initialize the maxlength for each column during its creation.... or to change the maxlength in runtime.

For example, i want to enter the length in the textbox (not in the grid)  and after pressing enter i want to set the length for the sellected column, i didnt find how to make it.

The activated editor receives a reference to a Cell object in Activate method. Using the Cell object you can get the column containing this cell and dynamically calculate the width of an editor.
