在 Blazor 中设置属性

Question

我花了太多时间试图完成一些应该非常简单的事情，所以请联系这个小组。 我只是试图更新 Blazor 表单的属性值，但它不执行代码——它只在浏览器页面上呈现代码。

我正在尝试将变量priorWorkspace 设置为rpt.WorkspaceName 的值作为@priorWorkspace = @rpt.WorkspaceName 但它不起作用并且rpt.WorkspaceName 被渲染。

显然，我是新来的，所以很好。 :-)

    <table class="table">
    <thead>
        <tr>
            <th>Select</th>
            <th>Workspace</th>
            <th>Report Name</th>
            <th>Report Desc</th>
        </tr>
    </thead>

    <tbody>
        @foreach (var rpt in rptObj)
        {
            <tr>
                @if (@priorWorkspace == @rpt.WorkspaceName)
                {
                    <td></td>
                    <td>@rpt.WorkspaceName</td>
                    <td>@rpt.ReportName</td>
                    <td>@rpt.ReportDesc</td>
                    }
                else 
                {
                    <td><input type="checkbox" value="@rpt.WorkspaceName" checked="@isChecked" @onchange="eventArgs => { CheckboxChanged(rpt, eventArgs.Value); }"></td>
                    <td>@rpt.WorkspaceName</td>
                    <td>@rpt.ReportName</td>
                    <td>@rpt.ReportDesc</td>
                    }
            </tr>
            <code>@priorWorkspace = @rpt.WorkspaceName</code>
        }
    </tbody>
</table>


@code {

    public string priorWorkspace = "";
    List<PowerBIWorkspace> rptObj;
}

我想这就是你想要的。 我没有测试它。

@{
    string priorWorkspace = "";
    foreach (var rpt in rptObj)
        {
            <tr>
                @if (priorWorkspace == rpt.WorkspaceName)
                {
                    <td></td>
                    <td>@rpt.WorkspaceName</td>
                    <td>@rpt.ReportName</td>
                    <td>@rpt.ReportDesc</td>
                    }
                else 
                {
                    <td><input type="checkbox" value="@rpt.WorkspaceName" checked="@isChecked" @onchange="eventArgs => { CheckboxChanged(rpt, eventArgs.Value); }"></td>
                    <td>@rpt.WorkspaceName</td>
                    <td>@rpt.ReportName</td>
                    <td>@rpt.ReportDesc</td>
                    }
            </tr>

            priorWorkspace = rpt.WorkspaceName;
        }
}

@code {

    //public string priorWorkspace = "";
    List<PowerBIWorkspace> rptObj;
}
