在C1DataGrid for Silverlight中,如果包含DataGridCheckBoxColumn类型的列,你会发现该列中单元格处于非编辑状态时,CheckBox都被显示成灰色。
本文也将主要介绍如何改变CheckBox列处于非编辑状态时的显示样式,基本思路是在LoadedCellPresenter事件中将C1.Silverlight.DataGrid.ReadOnlyCheckBox替换为正常的CheckBox,代码如下:
void c1DataGrid1_LoadedCellPresenter(object sender, C1.Silverlight.DataGrid.DataGridCellEventArgs e) { if (e.Cell.Column.GetType() == typeof(C1.Silverlight.DataGrid.DataGridCheckBoxColumn)) { CheckBox newCheckBox = new CheckBox(); System.Windows.Data.Binding bnd = new System.Windows.Data.Binding(); bnd.Source = e.Cell; bnd.Path = new PropertyPath("Value"); bnd.Mode = System.Windows.Data.BindingMode.TwoWay; newCheckBox.SetBinding(CheckBox.IsCheckedProperty, bnd); e.Cell.Presenter.Content = newCheckBox; e.Cell.Presenter.HorizontalContentAlignment = System.Windows.HorizontalAlignment.Center; e.Cell.Presenter.VerticalContentAlignment = System.Windows.VerticalAlignment.Center; } } 复制代码
