DataGridViewComboBoxColumn:限制MaxDropDownItems
我想知道如何限制DataGridViewComboBoxColumn
显示的项目数。 在简单的ComboBox
我们可以这样做:
comboBox1.IntegralHeight = false; //this is necessary to make it work!!! comboBox1.MaxDropDownItems = 3;
但是如何在DGV
的comboBox中做同样的DGV
?
创建ComboBoxColumn
,没有IntegralHeight
属性。
通过订阅DataGridViewEditControlShowing
事件,我已经通过我自己想出来了,并在其中使用此代码:
private void dataGridView1_EditingControlShowing( object sender, DataGridViewEditingControlShowingEventArgs e) { ComboBox cb = e.Control as ComboBox; if (cb != null) { cb.IntegralHeight = false; cb.MaxDropDownItems = 10; } }
现在下拉菜单工作,它显示为MaxDropDownItems
属性设置的行MaxDropDownItems
。
对于Visual Basic
Private Sub dgvDesp_EditingControlShowing( _ sender As Object, _ e As DataGridViewEditingControlShowingEventArgs) Handles dgvDesp.EditingControlShowing Dim cb As ComboBox = e.Control If cb.Items.Count > 0 Then cb.IntegralHeight = False cb.MaxDropDownItems = 10 End If End Sub
