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

Question

我正在尝试在 CRM 2015 online 中使用 fetchXml 结果填充子网格。 一开始的一个问题是document.getElementById("leadUmbrellaGrid"); 返回空值

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

}

我已经经历了这个和这个

我也试过window.parent.document.getElementById ，但在这两种情况下， .control都是 null 或 undefined 并最终得到：

类型错误：无法获取未定义或空引用的属性“SetParameter”

感谢您的帮助/提示。 谢谢，

Answer 1

这是解决方案：

1. 我们需要使用window.parent.document.getElementById

2. 等待control加载到 DOM 中。

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”，这是否仍然适用于 CRM 7.1？ 谢谢
