在中继器中保存下拉列表值？

Question

我已经在中继器内的 dropdownlist 上检索了我的数据库（DescriptionCode）。

现在，我尝试在数据库中保存/添加/插入下拉列表的选定值，但

失败了。

非常感谢任何帮助。谢谢！

 protected void GeneralRepeater_OnItemDataBound(object sender,
                                               RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item ||
            e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DropDownList myDDL = (DropDownList)e.Item.FindControl("GeneralDDL");
            Diagnosis oDiagnosis = new Diagnosis();
            PlanOfCare oPlanOfCare = new PlanOfCare();
            DataView dv = new DataView(oDiagnosis.GetDiagnosis());
            myDDL.DataSource = PatientDiagnosis1;
            myDDL.DataTextField = "DiagnosisCode";
            myDDL.DataValueField = "DiagnosisCode";
            myDDL.DataBind();

            //PUT AN EMPTY FIELD FOR DROPDOWNLIST
            ListItem LI = new ListItem("", "");
            myDDL.Items.Insert(0, LI);
            myDDL.SelectedValue = "0";



        }
    }


 protected void cmdSave_Click(object sender, EventArgs e)
    {
    oPlanofCareSave.DiagnosesCode = //[1]this must the selected value of dropdownlist inside of repater
    PlanSave(ooPlanofCareSave);
}

Answer 1

cmdSave 按钮怎么样，它位于 Repeater 内部，

您需要找出每一行中的 myDDL，并且对于每一行，您都需要获取该值。

foreach (RepeaterItem rptItem in RepeaterName.Rows)
{
         DropDownList myDDL = (DropDownList)rptItem.FindControl("myDDL");
}

Answer 2

DropDownList myDDL = (DropDownList)GeneralRepeater.Items[indexvalue].FindControl("GeneralDDL");

oPlanofCareSave.DiagnosesCode = myDDL.SelectedValue;

这样做很容易
