Question

Now I am trying to use a button on the parent page to a usercontrol.

There is a checkboxlist on the usercontrol, and its datasource is read from database

the checkboxlist didn’t load correctly. it is like:

OnlineRenewa_draft1.tbl_LanguageChoices OnlineRenewa_draft1.tbl_LanguageChoices OnlineRenewa_draft1.tbl_LanguageChoices
OnlineRenewa_draft1.tbl_LanguageChoices OnlineRenewa_draft1.tbl_LanguageChoices OnlineRenewa_draft1.tbl_LanguageChoices

is it about postback issue?
Any idea?
thanks

 protected void Page_Load(object sender, EventArgs e)
    {
        //if (!IsPostBack) { 
            List<tbl_LanguageChoices> LanguageList = ((List<tbl_LanguageChoices>)Cache["LanguageChoise"]);

            otherlanguage.DataSource = LanguageList;
            otherlanguage.DataBind();
            otherlanguage.DataTextField = "Languages";
            otherlanguage.DataValueField = "GUID";
}

Answer 1

You’re first databinding the checkboxlist’s to the DataSource and then setting DateValueField and DataValueField. DataBind should be the last step.

otherlanguage.DataSource = LanguageList;
otherlanguage.DataTextField = "Languages";
otherlanguage.DataValueField = "GUID";
otherlanguage.DataBind();
