Question

在Razor中我使用ADO.NET List綁定了Web網格。然後，如果空列表需要設置Web網格可見。請幫我

Answer 1

只需測試模型對象的空值。見下面的工作代碼：

@{ 
     if(Model != null) 
     { 

      var grid = new WebGrid(Model.ToList),canPage:true, rowsPerPage: 15, 
      selectionFieldName: "selectedRow", ajaxUpdateContainerId: "gridContent"); 
      grid.Pager(WebGridPagerModes.All); 
      <div id="gridContent"> 
       @grid.GetHtml(tableStyle: "webGrid", 
         headerStyle: "blue-gradient", 
         alternatingRowStyle: "alt", 
         selectedRowStyle: "select", 
         columns: grid.Columns(
         //grid.Column(null,null, format: @<input type="hidden" name="IDHidden" value="@item.EventID"/>), 
         //grid.Column("", format: @<text>@Html.ActionLink("Select", "Submit", new { CaseId = item.File_Number }) </text>), 
         grid.Column("File_Number", "File Number", format: @<text>@Html.ActionLink(((string)item.File_Number), "Review", new { CaseId = item.File_Number }) </text>), 
         grid.Column("File_Name", "File Name"), 
         grid.Column("Attorney", "Attorney"), 
         grid.Column("Reviewer", "Reviewer"), 
         grid.Column("Department", "Department"), 
         grid.Column("Review_Status", "Review Status"), 
         grid.Column("Claim_Number", "Claim Number"), 
         grid.Column("Status", "Case Status") 
       )) 
      </div> 
     } 

    } 

    Test for nulls and then if true, simply don't render the WebGrid at all
