Question

因此，当用户单击组合框中的customersID时，我的组合框用于填充数据网格视图，它将弹出网格。我有填充代码，但问题是它们的组合框本身没有重置。它仍然显示已选择的当前值。我想知道在选定的索引事件后重置组合框是可行的。下面的代码是我如何得到我的组合框。

       ' after a command and connection was made

        customerAdapt = New SqlDataAdapter(customerQuery,con)

        customerSet = New DataSet
        customerAdapt.Fill(customerSet)


         customerCb.DataSource = adoAddtRs.tables(0)
      customerCb.DisplayMember = "custID"
      customerCb.ValueMember = "custID"
     customerCb.Visible = False
     customerCb.DropDownStyle = ComboBoxStyle.DropDownList

Answer 1

尝试这段编码

customerCb.selectedindex = -1

Combobox将第一行显示为显示
