SetParameter("fetchXml"，FetchXml)不支持2016年在线客户关系管理

Question

我有这样的代码：

function FilterCasesSubgrid() {
    //var CasesSubgrid = Xrm.Page.getControl("contact").getGrid();
    var CasesSubgrid = window.parent.document.getElementById("contact");

    if(CasesSubgrid==null){ 
    setTimeout(function () { FilterCasesSubgrid(); }, 2000); //if the grid hasn’t loaded run this again when it has 
    return;
    }
    var fetchXml ="<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>"+
    "<entity name='contact'>"+
    "<attribute name='fullname' />"+
    "<filter type='and'>"+
    "<condition attribute='fullname' operator='eq' value='s%' />"+
    "</filter>"+
    "</entity>"+
    "</fetch>";
    //Here i set the fetchxml directly to subgrid
    CasesSubgrid.control.SetParameter("fetchXml", fetchXml); //set the fetch xml to the sub grid 
    CasesSubgrid.control.Refresh(); //refresh the sub grid using the new fetch xml 
}

错误：

TypeError:无法读取FilterCasesSubgrid处未定义的属性“SetParameter”

Answer 1

此代码不受支持，因此您不应该期望它能够工作。使用任何直接访问DOM (即window.parent.document.getElementById)或使用MSDN SDK中未定义的函数的函数都是不受支持的，应该避免使用。

但是，假设您只需要添加一个筛选器，就可以通过设置现有的FetchXML查询来支持这样做：

var myView = {
    entityType: 1039, // SavedQuery
    id:"{3A282DA1-5D90-E011-95AE-00155D9CFA02}", 
    name: "My Custom View"
}

//Set the view using ContactsIFollow
Xrm.Page.getControl("Contacts").getViewSelector().setCurrentView(myView);

Answer 2

您需要等待元素和控件属性(CasesSubgrid.control)。

这里已经回答了这个问题

Answer 3

以下是解决办法：

• 我们需要使用window.parent.document.getElementById
• 等待控件加载到DOM中。

所以代码看起来是这样的：

​

function FilterCasesSubgrid() 
{
    //var CasesSubgrid = Xrm.Page.getControl("contact").getGrid();
    var CasesSubgrid =   window.parent.document.getElementById("contact");

    if(CasesSubgrid==null)
    { 
    setTimeout(function () { FilterCasesSubgrid(); }, 2000); //if the grid hasn’t loaded run this again when it has 
    return;
    }
    var fetchXml ="<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>"+
    "<entity name='contact'>"+
    "<attribute name='fullname' />"+
    "<filter type='and'>"+
    "<condition attribute='fullname' operator='eq' value='s%' />"+
    "</filter>"+
    "</entity>"+
    "</fetch>";
    //Here i set the fetchxml directly to subgrid
  if(CasesSubgrid.control != null)
    {
    CasesSubgrid.control.SetParameter("fetchXml", fetchXml); //set the fetch xml to the sub grid 
    CasesSubgrid.control.Refresh(); //refresh the sub grid using the new fetch xml 
      }
  else
    {
       setTimeout(CasesSubgrid, 500);
      }
}
