问题描述

我使用了以下代码:

I used this code:

protected void Button1_Click(object sender, EventArgs e)
        {


            using (SPSite site = new SPSite(Convert.ToString(SPContext.Current.Web.Url)))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    using (SPWeb web1 = site.OpenWeb("Sales"))
                    {

                        web.AllowUnsafeUpdates = true;
                        SPList list1 = web.Lists["AviList1"];
                        SPList list2 = web1.Lists["AviList2"];
                        if (list1 != null)
                        {


                            string fieldXML = "<field displayname="MyLookUpColumn" type="Lookup" required="FALSE" list="" list1.id="" webid="" web.id="" name="MylookUpColumn" showfield="" />";
                            list2.Fields.AddFieldAsXml(fieldXML, true, SPAddFieldOptions.AddFieldToDefaultView);


                        }
                    }
                }
            }


}

AviList1位于rootsite上，有两列:Name列(单行文本类型)和Country列(choice类型).

当我运行此代码时，列''MyLookUpColumn''被添加到AviList2中，其值是我在AviLIst1的国家/地区列中输入的值.但是问题是当我在AviLIst2中进行输入时.

发生了什么，而不是在AviList2的MyLookUpColumn列中保存值，而是在AviList2的该列中保存了#err.

请尽快解决我的问题.请发送代码.谢谢.

请仔细阅读我的整个问题&然后请回复.
非常感谢.......

AviList1 is on rootsite and has two columns: Name column which is of type single line text and Country column which of type choice.

When I run this code a column ''MyLookUpColumn'' is added in AviList2 with values that I have made entries in Country column of AviLIst1.But problem is that when I make entries in AviLIst2.

What is happening, instead of saving value in MyLookUpColumn column of AviList2,it is saving #err in that column of AviList2.

Please solve my problem as soon as possible.Plz send the code.Thanks in advance.

Please read my whole problem carefully & then please reply.
Thanks a lot................

AviList2
