Question

我正在使用 WebGrid 来显示项目列表，列表中的某些项目被禁用，所以我想让它在网格中变暗，为此我必须设置行如果禁用该项，则为灰色的类，我不知道如何根据条件设置行类

这是我的示例代码

  var grid = new WebGrid(Model, canPage: true, rowsPerPage: 20);
                @grid.GetHtml(tableStyle: "grid",
                                rowStyle: "gridrow",
                                alternatingRowStyle: "gridrow_alternate",
                                mode: WebGridPagerModes.All,
                                numericLinksCount: 10,
                                columns: grid.Columns(
                                    grid.Column("Name", "Name", item => (item.LocationData[0].Name), canSort: true, style: "width:60%"),
                                    grid.Column("Url", "Url", canSort: true, style: "width:60%"),
                                    grid.Column("Edit", "", @<a href='../VenHome/Edit/@item.ID' ><img src='/content/icons/edit.png'
                                        alt='Edit' />
                                    </a>, style: "width:150px"),
                                    grid.Column("Delete", "", @<a href='#' id='Delete' itemId='@item.ID' title='@item.LocationData[0].Name'><img
                                        src='/content/icons/delete.png' alt='Delete' />
                                    </a>, style: "width:150px"),
                                    grid.Column("Details", "", @<a href="../VenHome/Details/@item.Id" title="Details">
                                        <img src="../../Content/Icons/Details.png" alt="Details" /></a>)
                                    ));

            }

我使用JQuery找到了解决这个问题的方法，我为网格列内部HTML添加了一个CSS类属性这是前面的代码，添加了属性

 @{
        var grid = new WebGrid(Model, canPage: true, rowsPerPage: 20);
                @grid.GetHtml(tableStyle: "grid",
                                rowStyle: "gridrow",
                                alternatingRowStyle: "gridrow_alternate",
                                mode: WebGridPagerModes.All,
                                numericLinksCount: 10,
                                columns: grid.Columns(
                                    grid.Column("Name", "Name", item => (item.LocationData[0].Name), canSort: true, style: "width:60%"),
                                    grid.Column("Url", "Url", canSort: false, style: "width:60%"),
                                    grid.Column("Edit", "", @<a href='../VenHome/Edit/@item.ID' ><img src='/content/icons/edit.png' alt='Edit' /></a>, style: "width:150px"),
                                    grid.Column("Delete", "", @<a href='#' id='Delete' class="temp" removed="@item.Removed" itemId='@item.ID' title='@item.LocationData[0].Name'><img src='/content/icons/delete.png' alt='Delete'  /></a>, style: "width:150px"),
                                    grid.Column("Details", "", @<a href="../VenHome/Details/@item.Id" title="Details">
                                        <img src="../../Content/Icons/Details.png" alt="Details" /></a>)
                                    ));

            }

这是修改后的代码

  grid.Column("Delete", "", @<a href='#' id='Delete' class="temp" removed="@item.Removed" itemId='@item.ID' title='@item.LocationData[0].Name'><img src='/content/icons/delete.png' alt='Delete'  /></a>, style: "width:150px"),

我在删除链接中添加了一个类“temp”，并且还添加了一个属性“removed”具有条件值，并且我添加了以下JQuery代码

 $(".temp").each(function (index, element) {
            if (($(element).attr("removed")) == "False") {
                $(element).parent().parent().attr("class", "deleted");

                $(element).find("img").attr("src", "../../content/icons/deleted.png");
            }
        });

注意：如果该项目已删除，则会将该行显示为灰色

我正在禁用在WebGrid中定义为列的链接，这也适用于您。我将颜色设置为灰色并且onclick在禁用条件时返回false。否则颜色为黑色，onclick返回true，如下所示：

@{
    bool enableLink = false;
    var link = "false";
    var color = "grey";
    if (enableLink) { link="true"; color="black"; }         
}

            <div>@grid.GetHtml( tableStyle: "grid",
              headerStyle: "head",
              alternatingRowStyle: "alt",
              columns: grid.Columns(                
              grid.Column(format: @<a href="http://www.whereverYouLinkTo.com" style="color:@color" onclick="return @link">Edit</a>), 
              grid.Column("FirstName", header:"First"),
              grid.Column("LastName", header:"Last")))

</div>

我希望这有帮助！
