在列表中添加序号,序号随着列的增加而增加,同时又不会影响到ItemSource的赋值,即不需在列表绑定的类中添加一个绑定序号的字段。
定义类:
1 public class NumColumn : Telerik.Windows.Controls.GridViewColumn 2 { 3 public override FrameworkElement CreateCellElement(Telerik.Windows.Controls.GridView.GridViewCell cell, object dataItem) 4 { 5 TextBlock textBlock = cell.Content as TextBlock; 6 7 if (textBlock == null) 8 { 9 textBlock = new TextBlock(); 10 } 11 12 textBlock.Text = (this.DataControl.Items.IndexOf(dataItem) + 1).ToString(); 13 14 return textBlock; 15 } 16 17 }
然后在xaml中引用这个类:
xmlns:local="clr-namespace:CSNMSSL.csnms.controls(命名空间)"
<telerik:RadGridView ShowGroupPanel="False" AutoGenerateColumns="False" IsReadOnly="True" IsFilteringAllowed="False" RowIndicatorVisibility="Collapsed" CanUserFreezeColumns="False" CanUserSelect="True" RowStyle="{StaticResource TssGridViewRowStyle}" x:Name="cutList" Grid.Row="0" FontFamily="Arial" FontSize="12" > <telerik:RadGridView.Columns> <local:NumColumn Header="序号" Width="40"/>
