如何以编程方式更改 datagridview 中的组合框所选项目？

Answer 1

Using brute force. Assuming you want to change the value of a DataGridViewComboBoxCell in the column colIndex and row rowIndex , and the value index of the combobox is in the 0 position:

For jj = 0 To CType(myDatagrid.Rows(rowIndex).Cells(colIndex), DataGridViewComboBoxCell).Items.Count - 1
    If CInt(CType(myDatagrid.Rows(colIndex).Cells(rowIndex), DataGridViewComboBoxCell).Items(jj).row(0)) = myValue Then
        myDatagrid.Rows(rowIndex).Cells(colIndex).Value = CType(myDatagrid.Rows(rowIndex).Cells(colIndex), DataGridViewComboBoxCell).Items(jj).row(0)
    End If
Next

Yes, I know this question was asked 6 years ago, but I haven't found the answer anywhere and I found it by myself. Hope it will be useful to someone.

The reason why DataGridViewComboBoxCell has not selectedIndex or selectedValue properties is beyond my grasp.

Answer 2

In the DataGridView CellClick event:

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
     string item = dataGridView1.SelectedCells[0].Value.ToString();
     comboBox1.SelectedItem = item;
}
