Dynamics CRM 2015 Online：SubGrid 的 control.SetParameter 方法不可用

Question

我正在尝试使用 CRM 2015 在线中的 fetchXml 结果填充子网格。一开始的一个问题是 document.getElementById("leadUmbrellaGrid"); returns null

function filterSubGrid() {

    var leadwithSameNameGrid = Xrm.Page.getControl("leadUmbrellaGrid").getGrid();//HAVE TRIED window.parent.document.getElementById("leadUmbrellaGrid"); //grid to filter
    var currentleadId = Xrm.Page.data.entity.getId();;
    if (leadwithSameNameGrid == null) {

        setTimeout('filterSubGrid()', 500);
        return;
    }
    //fetch xml code 
    var fetchXml = "<fetchxml goes here>";


    leadwithSameNameGrid.control.SetParameter("fetchXml", fetchXml); //set the fetch xml to the sub grid   
    leadwithSameNameGrid.control.refresh(); //refresh the sub grid using the new fetch xml

}

我已经过了this and this

我也尝试了 window.parent.document.getElementById，但在这两种情况下，.control 都为 null 或未定义，最终结果为：

TypeError: 无法获取未定义或空引用的属性 'SetParameter'

感谢您的 help/tips。谢谢，

Answer 1

解决方法如下：

我们需要使用window.parent.document.getElementById
等待 control 在 DOM 中加载。

所以代码看起来像这样：

function filterSubGrid() 
{

    var leadwithSameNameGrid = window.parent.document.getElementById("leadUmbrellaGrid");
    var currentleadId = Xrm.Page.data.entity.getId();;
    if (leadwithSameNameGrid == null) 
    {
        setTimeout(filterSubGrid, 500);
        return;
    }

    //fetch xml code 
    var fetchXml = "<fetchxml goes here>";
    if (leadwithSameNameGrid.control != null) 
    {
        leadwithSameNameGrid.control.SetParameter("fetchXml", fetchXml); //set the fetch xml to the sub grid   
        leadwithSameNameGrid.control.refresh(); //refresh the sub grid using the new fetch xml
    } 
    else 
    {
        setTimeout(filterSubGrid, 500);
    }
}

function filterSubGrid() {

        var leadwithSameNameGrid = window.parent.document.getElementById("leadUmbrellaGrid");
        var currentleadId = Xrm.Page.data.entity.getId();;
        if (leadwithSameNameGrid == null) {

            setTimeout('filterSubGrid()', 500);
            return;
        }
        //fetch xml code 
        var fetchXml = "<fetchxml goes here>";
        if (relatedProjectsSubGrid.control != null) {
        leadwithSameNameGrid.control.SetParameter("fetchXml", fetchXml); //set the fetch xml to the sub grid   
        leadwithSameNameGrid.control.refresh(); //refresh the sub grid using the new fetch xml
          } else {
        setTimeout('filterSubGrid()', 500);
        }

    }

我试过这个，但不太明白你从哪里得到 "relatedProjectsSubGrid.control"，这对 CRM 7.1 是否仍然有效？谢谢
