Question

我正在使用C＃CSOM代码创建Sharepoint列表视图。我使用ViewCreationInformation来创建我的视图。我在编写查询时遇到了问题。

写这个有用：

            ViewCollection viewColl = list.Views;
            string[] viewFields = {"Id", "Action", "Created", "Created By"};
            ViewCreationInformation creationInfo = new ViewCreationInformation();
            creationInfo.Title = "FromCode";
            creationInfo.ViewFields = viewFields;
            creationInfo.Query = @"<Where><Neq><FieldRef Name=""ConfidentialDocument""/><Value Type=""Choice"">No</Value></Neq></Where><GroupBy><FieldRef Name=""TemplateName"" /><FieldRef Name=""Title"" /></GroupBy><OrderBy><FieldRef Name=""Created"" Ascending=""True"" /></OrderBy>";
            creationInfo.ViewTypeKind = ViewType.Html;
            creationInfo.RowLimit = 30;
            creationInfo.Paged = true;
            creationInfo.SetAsDefaultView = true;
            viewColl.Add(creationInfo);

但如果我将查询更改为：

            creationInfo.Query = @"<Where><Neq><FieldRef Name=""ConfidentialDocument""/><Value Type=""Choice"">No</Value></Neq></Where><GroupBy Collapse=""TRUE"" GroupLimit=""30""><FieldRef Name=""TemplateName"" /><FieldRef Name=""Title"" /></GroupBy><OrderBy><FieldRef Name=""Created"" Ascending=""True"" /></OrderBy>";

然后视图显示错误： TypeError: Unable to get property 'substring' of undefined or null reference

您可以查看链接或这是错误： TypeError：无法获取属性＆＃39; substring＆＃39;未定义或空引用

  TypeError: Unable to get property 'substring' of undefined or null referenceTypeError: Unable to get property '_events' of undefined or null reference

有没有人对此有任何想法？我搜索了很多地方，到处都找到了类似的代码。我不知道为什么这段代码不起作用。

好的问题出在GroupLimit =＆＃34;＆＃34; 30＆＃34;＆＃34;。没有GroupLimit的查询工作完全正常。

        creationInfo.Query = @"<Where><Neq><FieldRef Name=""ConfidentialDocument""/><Value Type=""Choice"">No</Value></Neq></Where><GroupBy Collapse=""TRUE""><FieldRef Name=""TemplateName"" /><FieldRef Name=""Title"" /></GroupBy><OrderBy><FieldRef Name=""Created"" Ascending=""True"" /></OrderBy>";

Caml查询不适用于视图创建共享点
