求助！datagridview如何判断行标题被选中？

[ddt36524]

求教如何判断当前选择是通过行标题栏进行的行选择的？

下面这段代码好像不行。。。

        Dim intRow As Integer 

        intRow = DataGridView1.CurrentCell.RowIndex
        If DataGridView1.Rows(intRow).HeaderCell.Selected = True Then
            。。。。
        End if

还有怎么取得选择行的开始行和结束行？

选择行的开始行和结束行 int start = -1, end = -1; for (int i = 0; i < datagridview1.SelectedRows.Count; i++) { if (start == -1 || start > i) start = i; if (end == -1 || end < i) end = i; }

判断是否通过标题栏选择的行 Dim intRow As Integer intRow = DataGridView1.CurrentCell.RowIndex If DataGridView1.Rows(intRow).HeaderCell.State= DataGridViewElementStates.Selected Then 。。。。 End if

选择行的开始行和结束行 int start = -1, end = -1; for (int i = 0; i < datagridview1.SelectedRows.Count; i++) { if (start == -1 || start > i) ……

最好vb.net 代码。。

我把它加到DataGridView1.SelectionChanged事件里，可选中整行后DataGridView1.Rows(intRow).HeaderCell.State 的值是None {0} 。。。

额，依然寻求帮助中。。。

'在DataGridView的RowHeaderMouseClick的事件中进行判断 Private Sub DataGridView1_RowHeaderMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.RowHeaderMouseClick MsgBox(DataGridView1.CurrentCell.RowIndex) End Sub

还有怎么取得选择行的开始行和结束行？——>

   Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim MaxRow As Integer = 0, MinRow As Integer = 0
        For i As Integer = DataGridView1.Rows.Count - 1 To 0 Step -1
            If DataGridView1.Rows(i).Selected = True Then
                If MaxRow = 0 Then MaxRow = i Else MinRow = i
            End If
        Next
        MsgBox("您选择的最大行号是：" & MaxRow.ToString & "最小行号是：" & MinRow.ToString)
    End Sub

奇怪，我不能编辑自己回复的贴子

'将8楼的回复修正一下，因为如果只选择一行的话，结果不准确
        Dim MaxRow As Integer = -1, MinRow As Integer = -1
        For i As Integer = DataGridView1.Rows.Count - 1 To 0 Step -1
            If DataGridView1.Rows(i).Selected = True Then
                If MaxRow = -1 Then
                    MaxRow = i : MinRow = i
                Else
                    MinRow = i
                End If
            End If
        Next
        MsgBox("您选择的最大行号是：" & MaxRow.ToString & "最小行号是：" & MinRow.ToString)
