You override the DataGridExColumnStylesCollectionEditor class
public class DataGridExColumnStylesCollectionEditor : System.ComponentModel.Design.CollectionEditor

{

public DataGridExColumnStylesCollectionEditor(Type type) : base(type)

{ }

protected override System.Type[] CreateNewItemTypes()

{

return new Type[] {

typeof(DataGridTextBoxColumn),

typeof(DataGridDigitsTextBoxColumn)

//.......

};

}

}

//override the DataGridExTableStylesCollectionEditor class

public class DataGridExTableStylesCollectionEditor : System.ComponentModel.Design.CollectionEditor

{

public DataGridExTableStylesCollectionEditor(Type type) : base(type)

{

}

protected override System.Type[] CreateNewItemTypes()

{

return new Type[] {typeof(DataGridExTableStyle)};

}

}

//override the DataGridExTableStyle class

public class DataGridExTableStyle : System.Windows.Forms.DataGridTableStyle

{

[Editor(typeof(DataGridExColumnStylesCollectionEditor), typeof(UITypeEditor))]

public new GridColumnStylesCollection GridColumnStyles

{

get {return base.GridColumnStyles;}

}

protected override DataGridColumnStyle CreateGridColumn(PropertyDescriptor prop, bool isDefault)

{

return base.CreateGridColumn(prop, isDefault);

}



}



public class DataGridComboBoxColumn : DataGridTextBoxColumn

{

private ComboBox ColumnComboBox = null;

// Implement this class

}



//And

public class DataGridEx : System.Windows.Forms.DataGrid

{

[Editor(typeof(DataGridExTableStylesCollectionEditor), typeof(UITypeEditor))]

public new GridTableStylesCollection TableStyles

{

get {return base.TableStyles;}

}

}
