怎么让DataGridViewComboxColumn里的COMBOBOX显示指定行啊？

Question

这样试试看：private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (e.Control is DataGridViewComboBoxEditingControl)
{
DataGridViewComboBoxEditingControl cmb = e.Control as DataGridViewComboBoxEditingControl;
if (cmb.Items.Count > 0)
{
cmb.SelectedIndex = 0;
}
}
}

Answer 1

把你的data source的值改了不就行了

Answer 2

我的测试代码如下，没有死机：private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (e.Control is DataGridViewComboBoxEditingControl)
{
DataGridViewComboBoxEditingControl cmb = e.Control as DataGridViewComboBoxEditingControl;
if (cmb.Items.Count == 0)
{
cmb.Items.Add("123");
}
cmb.SelectedIndex = 0;
}
}

Answer 3

this.data_view_sts.Rows[0].Cells[0].Value = "aa";
             this.data_view_sts.Rows[0].Cells[1] = dc;
我是直接这样设值的
