winforms datagrid在编辑时将列更改为组合框

Question

我的winforms应用程序上有一个datagrid列。当用户选择特定单元格时，单元格应转向数据绑定组合框，用户可以编辑单元格。

如何在editmode上显示组合框？

Answer 1

您在EditingControlShowing活动中有什么？

void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
 BindingSource bindingSource = this.dataGridView1.DataSource as BindingSource;
 Person person = bindingSource.Current as Person;
 BindingList<personType> bindingList = this.FindPersonTypes(person);

 DataGridViewComboBoxEditingControl comboBox = e.Control as DataGridViewComboBoxEditingControl;
 comboBox.DataSource = bindingList;
}

• 为了将细胞转换为组合框：

this.yourdatagridname.Rows [x] .Cells [y] = new DataGridComboBoxCell（）;

其中x，y表示您要转换的单元格

• 为了使其可编辑：

this.yourdatagridname.Rows [x] .Cells [y] .ReadOnly = false;
