在 winform 中 DataGrid 中实现点击任一单元格都选中当前行

先需要重写一个方法：C#:

internal class DataGridNoActiveCellColumn : System.Windows.Forms.DataGridTextBoxColumn

{

//重载DataGridTextBoxColumn类的Edit方法,以便使点击DataGrid中任一单元格都选中当前行

protected override void Edit(CurrencyManager source, int rowNum, Rectangle bounds, bool readOnly, string instantText, bool cellIsVisible)

{

int SelectedRow = rowNum;

this.DataGridTableStyle.DataGrid.Select(SelectedRow);

}

vb.net :

Friend Class DataGridNoActiveCellColumn

Inherits System.Windows.Forms.DataGridTextBoxColumn

'重载DataGridTextBoxColumn类的Edit方法,以便使点击DataGrid中任一单元格都选中当前行

Protected Overloads Overrides Sub Edit(ByVal [source] As CurrencyManager, ByVal rowNum As Integer, ByVal bounds As Rectangle, ByVal [readOnly] As Boolean, ByVal instantText As String, ByVal cellIsVisible As Boolean)

Dim SelectedRow As Integer = rowNum

Me.DataGridTableStyle.DataGrid.Select(SelectedRow)

End Sub

End Class

设置datagrid样式：

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim tab As New DataTable("mytab")

For i As Int32 = 0 To 1

tab.Columns.Add(New DataColumn("A" & i, Type.GetType("System.Decimal")))

tab.Columns(1).Expression = "Avg(a0)"

Dim r As DataRow

For i As Int32 = 0 To 10

r = tab.NewRow

r("A0") = 5 + i

tab.Rows.Add(r)

Me.DataGrid1.DataSource = tab

Dim tabStyle As New DataGridTableStyle

Dim rCell As New DataGridNoActiveCellColumn

rCell.MappingName = tab.Columns(0).ColumnName

rCell.HeaderText = tab.Columns(0).ColumnName

tabStyle.GridColumnStyles.Add(rCell)

rCell.MappingName = tab.Columns(1).ColumnName

rCell.HeaderText = tab.Columns(1).ColumnName

rCell.Width = 100

tabStyle.GridColumnStyles.Add(rCell)

tabStyle.MappingName = tab.TableName

Me.DataGrid1.TableStyles.Add(tabStyle)

End Sub
