asp.net - 如何阻止 ASP.NET 更改 ID 以执行某些操作

Question

我正在创建动态单选按钮列表

Dim rdbQuestion As New RadioButtonList

并且有动态ID为

rdbQuestion.ID = "Question_" & row("Id").ToString

并且当页面呈现单选按钮列表的 id 更改为这样的

AssessmentPerforma_Question_1, AssessmentPerforma_Question_2, AssessmentPerforma_Question_3..... AssessmentPerforma_Question_n

如何阻止 asp.net 更改 ID 以执行这样的操作

Sub btnSave_click(ByVal sender As Object, ByVal e As EventArgs)

        Dim rbl As RadioButtonList = DirectCast(Page.FindControl("Question_1"), RadioButtonList)
        Response.Write(rbl.SelectedValue)
End Sub

Answer 1

添加这一行....

rbdQuestion.ClientIDMode = ClientIDMode.Static
