如何在vb.net中单击组合框项时更新文本框项

问题描述

单击组合框项后，我在更改文本框中的项目时遇到问题。我在表格设备中添加了像设备ID，设备项目（组合框），模型（组合框），数量，序列号和状态等项目。我希望在编辑equipmentItem（组合框）后，项目状态（文本框）自动从可用变为不可用。任何人都可以帮助我??

I have a problem to change already item in textbox after click combo box item. I add item like equipmentID,equipmentItem(combobox),model(combobox),quantity, serialnumber and status in form Equipment. I want item status(textbox) change automatic from available to unvailable after edit the equipmentItem(combobox). Anybody can help me??

推荐答案

<asp:DropDownList ID="SomeComboBox" runat="server" AutoPostBack="True"></asp:DropDownList>

那么您将需要代码来更改VB代码中SelectedIndexChanged事件中的文本框。这样的事情：

Then you will need code to change the textbox in the SelectedIndexChanged event in the VB code. Something like this:

Private Sub SomeComboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles SomeComboBox.SelectedIndexChanged
   'Code to change textbox here
   If SomeTextBox.Text = "available" Then SomeTextBox.Text = "unavailable"
End Sub
