以编程方式从另一个按钮单击 DataGridView 按钮单元格

Question

我有一个关于DataGridView.NET 中的控制的问题。

我DataGridView从工具箱中插入了一个，并将其与我在 Access 中设置的数据库连接起来。然后我添加了一列，其中包含任务面板编辑列中的按钮DataGridView。

按钮的点击事件DataGridView工作没有问题！

DataGridView当我单击DataGridView. 我该怎么做？

DataGridView的代码是：

Private Sub dgvAnimSel_CellContentClick(sender As Object, e As DataGridViewCellEventArgs) _
    Handles dgvAnimSel.CellContentClick
    Dim V As String = dgvAnimSel.Rows(e.RowIndex).Cells(0).Value
    If e.ColumnIndex = 3 Then
        If V = 1 Then
            If A1 = 1 Then
                'this is the uncheck state
                Me.dgvAnimSel.CurrentCell.Style.BackColor = Color.White
                Me.dgvAnimSel.CurrentCell.Style.ForeColor = Color.Black
                Me.dgvAnimSel.CurrentCell.Value = "Select"
                ItemTextNew = ItemTextOr + "1"
                ItemName = ListView1.FindItemWithText(ItemTextNew, False, 0, True)
                ListView1.Items.Remove(ItemName)
                A1 = 0
            Else
                'this is the check state
                Me.dgvAnimSel.CurrentCell.Style.BackColor = Color.Green
                Me.dgvAnimSel.CurrentCell.Style.ForeColor = Color.White
                Me.dgvAnimSel.CurrentCell.Value = "Selected"
                a = ListView1.Items.Add(" " + "Animation 1 ", 0)
                A1 = 1
            End If
        End If
End Sub

先感谢您！

Answer 1

您可以使用以下任一选项：

• 通过创建 的实例并将其传递给事件处理程序方法CellContentClick，像普通方法一样调用DataGridViewCellEventArgs事件处理程序。
• 或者将整个逻辑放入一个方法中，并在需要时从CellContentClick按钮DataGridView或Click按钮调用该方法。

示例 1 - 通过调用事件处理程序执行 DataGridView 按钮单元格的单击

要以编程方式单击特定行中的按钮，您可以CellContentClick使用合适的DataGridViewCellEventArgsase和您的DataGridViewas来调用您创建为事件的事件处理程序的方法sender：

Private Sub AnotherButton_Click(sender As Object, e As EventArgs) _
    Handles AnotherButton.Click
    ' zero based ColumnIndex of your button column= 3 (for example)
    ' zero based RowIndex that you want to click on its button column = 2 (for example)
    Dim arg = New DataGridViewCellEventArgs(3, 2) 
    DataGridView1_CellContentClick(DataGridView1, arg)
End Sub

Private Sub DataGridView1_CellContentClick(sender As Object, _
    e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
    MessageBox.Show(e.RowIndex.ToString())
End Sub

示例 2 - 将逻辑放入另一个方法中并在需要时调用该方法

作为另一个选项，您可以将与单击单元格按钮相关的逻辑放在方法中，依赖于Cell和Row对象，并且仅将合适的值传递给该方法。然后你可以在任何需要的地方调用该方法。

Private Sub DoSomething(rowIndex as Integer, columnIndex as Integer)
    MessageBox.Show(rowIndex.ToString())
End Sub

Private Sub AnotherButton_Click(sender As Object, e As EventArgs) _
    Handles AnotherButton.Click
    ' zero based ColumnIndex of your button column= 3 (for example)
    ' zero based RowIndex that you want to click on its button column = 2 (for example)
    DoSomething(2, 3) 
End Sub

Private Sub DataGridView1_CellContentClick(sender As Object, _
    e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
    DoSomething(e.RowIndex, e.ColumnIndex)
End Sub

    DoSomething(2, 3); 
}

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    DoSomething(e.RowIndex, e.ColumnIndex);
