自定义控件SelectedIndexChanged未触发

Posted 2021-04-15

我的自定义控件基于Telerik控件

Public Class ComboBoxСountries
    Inherits RadComboBox
End Class

使用控制

<mc:ComboBoxСountries ID="ComboCountry" runat="server" Width="100%" AutoPostBack="true"></mc:ComboBoxСountries>

事件

Protected Sub ComboCountry_SelectedIndexChanged(sender As Object, e As RadComboBoxSelectedIndexChangedEventArgs) Handles ComboCountry.SelectedIndexChanged
    ' not fired
End Sub

组合国家SelectedIndexChanged没有被解雇，但如果使用<telerik:RadComboBox />一切都好。如何解决这个问题呢？

答案

添加SelectedIndexChanged =“Combo Country SelectedIndexChanged”帮助

<mc:ComboBoxСountries ID="ComboCountry" runat="server" Width="100%" AutoPostBack="true" OnSelectedIndexChanged="ComboCountry_SelectedIndexChanged"></mc:ComboBoxСountries>
