绑宝DropDownList的显示Text与Value的问题。

绑定了一个DropDownList,其中一个为查询条件，绑定的值为like,显示文字为‘包含’，怎么在调用的时候这个DropDownList.Text却成了like...?我在界面上看到的明明也是‘包含’。高手看看这是怎么回事。。？ private void getSechose()
    {
        try
        {
            if (scn.State == ConnectionState.Closed)
            {
                scn.Open();
            }
            DataTable dt = new DataTable();
            dt = acc.GetSereachData("select * from ItItem_sefiled WHERE SeFileTable='ConditionA' and SeFileClass='Condition' and IsSelect=1 Order by SeOrderID");
            Ddcondition.DataSource = dt;
            Ddcondition.DataValueField = "SeFileID";
            Ddcondition.DataTextField = "SeFileName";
            Ddcondition.DataBind();
        }
        catch (Exception ex)
        {
           throw(ex);
        }
        finally
        {
            scn.Close();
        }
    }
 protected void bingdgv()

        try
        {
            if (txtSeValue.Text.Trim().ToString() == "")
            {
                return;
            }
            else
