Question

我有一个国家价值观的清单。这一清单在下降。各州的情况再次下降。当我选择国家时,国家下降应该与选定国家的居民相聚。我是新来的,我不知道如何做到这一点。

在C# I中,我想写一下类似的东西(请无视yn子):

if(state.country == countryDropDown.SelectedValue)
StateDropDown.add(State);

在InfoPath,我如何能够这样做?

Answer 1

在国家名单中,增加一个过滤器,以便你只显示属于该国的国家。 http://koobarspoint.blogspot.com/cading-drop-downs-with-infopath-2010.html” rel=“nofollow” http://koobarspoint.blogspot.com/ 201006/cascading-drop-downs-with-infopath-2010.html。 (不需要后面的代码)

if your data is in sharepoint list then you can use CAML query to fetch the data You need to create repeating field and bind that repeating field to staet dropdown. To fetch the state based on country selected is -

string strCountry=this.maindatasource.createnavigator().selectsinglenode("xpath of country dropdown",namespacemanager).value;

SPList oList = web.Lists["Name of List"];
SPQuery oQuery = new SPQuery();

oQuery.Query = "<Where><Eq><FieldRef Name= column name which contains countries  /><Value Type= Text >" + strCountry + "</Value></Eq></Where>";

SPListItemCollection oListItemCollection = oList.GetItems(oQuery);

foreach (SPListItem Item in oListItemCollection)
{                                           
   root.SelectSingleNode("xpath of field inside repeating table",NamespaceManager).SetValue(Item["Name of column which holds state"].ToString());

}
