如何手动下拉一个DataGridViewComboBoxColumn？ [英] How to manually drop down a DataGridViewComboBoxColumn?

问题描述

我有我的WinForms应用的一个DataGridViewComboBoxColumn一个DataGridView。我需要手动下拉（开放）这个DataGridViewComboBoxColumn，假设一个按钮被点击后。

I have a DataGridView with one DataGridViewComboBoxColumn in my WinForms application. I need to drop down (open) this DataGridViewComboBoxColumn manually, let's say after a button is clicked.

我之所以需要这个是我设置的SelectionMode为FullRowSelect，我需要点击2-3次打开组合框。我想点击组合框单元格，应立即降下来了。我想与CellClick事件做到这一点，或者是有没有其他办法？

The reason I need this is I have set SelectionMode to FullRowSelect and I need to click 2-3 times to open the combo box. I want to click on the combobox cell and it should drop down immediately. I want to do this with CellClick event, or is there any other way?

我搜索在谷歌和VS的帮助，但我还没有发现任何信息。

I am searching in Google and VS help, but I haven't found any information yet.

可有人帮忙吗？

推荐答案

我知道这不可能是理想的解决方案，但它确实创造一个单一的点击组合框，在细胞内的工作。

I know this can't be the ideal solution but it does create a single click combo box that works within the cell.

   Private Sub cell_Click(ByVal sender As System.Object, ByVal e As DataGridViewCellEventArgs) Handles DataGridView1.CellClick
        DataGridView1.BeginEdit(True)
        If DataGridView1.Rows(e.RowIndex).Cells(ddl.Name).Selected = True Then
            DirectCast(DataGridView1.EditingControl, DataGridViewComboBoxEditingControl).DroppedDown = True
        End If
    End Sub

，其中DDL是我加在GridView的组合框单元格。

where "ddl" is the combobox cell I added in the gridview.
