推荐答案

您需要指出您正在查看的ComboBox - 记住 cmb 是一个DataGridViewComboBox 列

You need to indicate which ComboBox you are looking at - remember that cmb is a DataGridViewComboBoxColumn

button_getID()
    'Assuming the ComboBox column is the first one ...
    Dim cmbc As DataGridViewComboBoxCell = DataGridView1.Rows(DataGridView1.CurrentRow.Index).Cells(0)

    Dim idUser as String
    idUser=cmbc.Value
End Sub

这些代码正常运行，非常感谢.... !!!!!

These code is working ,Thank you so much.... !!!!!
