01—WinForm中datagridview增加行号
在界面上拖一个控件dataGridView1,在datagridview添加行事件中添加如下代码:.
private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e){try{for (int i = 0; i < dataGridView1.Rows.Count; i++)this.dataGridView1.Rows[i].HeaderCell.Value = (i + 1).ToString();}catch{MessageBox.Show("处理异常:表格行标题添加异常");}}
这样表格中每次有新行增添就会被自动打标行号。
02—WPF中datagrid增加行号
WPF类似WinForm中datagridview的表格控件是datagrid,我们可以将行标题添加代码写在LoadingRow事件中:
①附件事件:
一般是在xmal窗体的cs初始化类中:
DG.LoadingRow += new EventHandler<DataGridRowEventArgs>(DG_LoadingRow);CM框架mvvm模式下:
[Event LoadingRow]=[DG_LoadingRow($source,$eventArgs)]"DG_LoadingRow事件如下:
private void DG_LoadingRow(object sender, DataGridRowEventArgs e){e.Row.Header = e.Row.GetIndex() + 1;}
03—WPF dev控件GridControl增加行号
dev控件GridControl没有行增添增添事件,我们可以用下面的方法去做:
增加控件引用空间
xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid"
<dxg:GridControl Name="grid" AutoGenerateColumns="AddNew"><dxg:GridControl.View><dxg:TableView RowIndicatorContentTemplate="{StaticResource rowIndicatorContentTemplate}"/></dxg:GridControl.View></dxg:GridControl
定义模板资源
<UserControl.Resources><DataTemplate x:Key="rowIndicatorContentTemplate"><StackPanel VerticalAlignment="Stretch"HorizontalAlignment="Stretch"><TextBlock Text="{Binding Path=RowHandle.Value}"TextAlignment="Center"Foreground="Gray"/></StackPanel></DataTemplate></UserControl.Resources>
