    t = DataSet11.Tables(0)
    'DataGridTableStyle controls the appearance of the grid for a table.
    Dim myGridTableStyle As DataGridTableStyle = New DataGridTableStyle()
    'Maps to the Products table.
    myGridTableStyle.MappingName = t.TableName
    'Add the myGridTableStyle to the TableStyles Collection of DataGrid. 
    DataGrid1.TableStyles.Add(myGridTableStyle)
    'Set the width of the Boolean Column "DisContinued" to 1.
    myGridTableStyle.GridColumnStyles("Discontinued").Width = 1

    Visual C# .NET Code

    //DataGridTableStyle controls the appearance of the grid for a table.
    DataTable t= dataSet11.Tables[0]; 
    DataGridTableStyle myGridTableStyle = new DataGridTableStyle();
    //Maps to the Products table.
    myGridTableStyle.MappingName = t.TableName;
    //Add the myGridTableStyle to the TableStyles Collection of DataGrid. 
    dataGrid1.TableStyles.Add(myGridTableStyle);
    //Set the width of the Boolean Column "DisContinued" to 1.
    myGridTableStyle.GridColumnStyles["Discontinued"].Width =1;
