ASP.NET mvc hiding webgrid columns

本文关键字：webgrid columns hiding mvc NET ASP 更新时间：2023-09-26

我的cshtml文件接收模型内的一些bool值(+数据构建webgrid)。根据bool值，一些webgrid列必须显示和隐藏，例如我有:Name, Surname, Job列在webgrid，但我有SurnameBool = 0，这意味着只有Name和Job列必须显示。我曾尝试使用其他答案的代码，但不幸的是，我是JavaScript新手，所以请告诉我如何在webgrid中添加css display : none属性到列，基于@if(ColumnNameBool)结果。

WebGrid grid = new WebGrid(item2.ListOfWorkData, canSort: false, rowsPerPage: 15);
<div id="divWebGrid" class="row">
    @if (item2.ListOfWorkData.Any())
    {
        @grid.GetHtml(
                             tableStyle: "table",
                             headerStyle: "table_HeaderStyle",
                             footerStyle: "table_PagerStyle",
                             rowStyle: "table_RowStyle",
                             alternatingRowStyle: "table_AlternatingRowStyle",
                             selectedRowStyle: "table_SelectedRowStyle",
                             columns: grid.Columns(
                                 grid.Column("ProjectName", @Resources.Localization.project, format: @<text>
                                    @if (Model.ColumnsNeeded.ProjectNameBool)
                                    {
                                        <span class="display-mode"><label id="ProjectNameLabel">@item.ProjectName</label></span>
                                    }
                                </text>,style : "hidden-column"),
                                 grid.Column("Activity", @Resources.Localization.activity, format: @<text>
                                    @if (Model.ColumnsNeeded.ActivityBool)
                                    {
                                        <span class="display-mode"><label id="ActivityLabel">@item.Activity</label></span>
                                    }
                                </text>, style: "p60"),
                                 grid.Column("ProjectEndDate", @Resources.Localization.start_date, format: @<text>
                                    @if (Model.ColumnsNeeded.ProjectStartDateBool)
                                    {
                                        <span class="display-mode"><label id="ProjectStartDate">@item.ProjectStartDate</label></span>
                                    }
                                </text>, style: "p60"),
                                 grid.Column("ProjectEndDate", @Resources.Localization.end_date, format: @<text>
                                    @if (Model.ColumnsNeeded.ProjectEndDateBool)
                                    {
                                        <span class="display-mode"><label id="ProjectEndDate">@item.ProjectEndDate</label></span>
                                    }
                                </text>, style: "p60")
                             )
                     )
    }

你应该创建一个null来源的网格:

WebGrid grid = new WebGrid<Your item type>(null, canSort: false, rowsPerPage: 15);

用source:

绑定你的网格

grid.Bind(item2.ListOfWorkData, rowCount: <total row count>, autoSortAndPage: false);

根据columnnamepool值创建列集:

var gridColumns = new List<WebGridColumn>();
@if(ColumnNameBool)
{          
      gridColumns.Add(grid.Column("ProjectName", 
                       @Resources.Localization.project, format: @<text>
                                @if (Model.ColumnsNeeded.ProjectNameBool)
                                {
                                    <span class="display-mode">
                                    <label id="ProjectNameLabel">
                                    @item.ProjectName</label>
                                    </span>
                                }
                            </text>,style : "hidden-column"));
               )
             //... add other required columns here
}
else
{
      //create here another list of columns that required
      gridColumns.Add(...);   
}

最后将列列表分配给grid:

@grid.GetHtml(<styles>, columns: gridColumns.ToArray());
