DevExpress MVC GridView：使用 DetailRowGetButtonVisibility

发布于 2024-12-13 07:20:02 字数 1203 浏览 2 评论 0原文

是否可以在 ASP.NET MVC 中使用 RowGetButtonVisibility 事件？在“正常”ASP.NET DevExpress 中，使用如下描述：

http://documentation.devexpress.com /#AspNet/DevExpressWebASPxGridViewASPxGridView_DetailRowGetButtonVisibilitytopic

我希望有可能显示/隐藏 GridView 中的详细信息按钮。

有什么想法可以做到这一点吗？

像这样的东西不起作用：

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<FOO>" %>
<%
Html.DevExpress().GridView(settings =>
{
    settings.Name = "resultsTable";
    settings.KeyFieldName = "ResultId";
    settings.CallbackRouteValues = new { Controller = "Results", Action = "ResultsPartial" };
    settings.Width = Unit.Percentage(100);
    settings.Height = Unit.Percentage(100);

    //...

    settings.PreRender = (sender, e) =>
    {
        MVCxGridView grid = (MVCxGridView)sender;
        grid.DetailRowGetButtonVisibility += (s_, e_) =>
        {
            if (some_condition == true)
            e_.ButtonState = GridViewDetailRowButtonState.Hidden;
        };
    };
})
.Bind(Model.Results)
.Render();

原文

Is it possible to use the event RowGetButtonVisibility in ASP.NET MVC?
In "normal" ASP.NET DevExpress is using this like described here:

http://documentation.devexpress.com/#AspNet/DevExpressWebASPxGridViewASPxGridView_DetailRowGetButtonVisibilitytopic

I want to have the possibility to show/hide the detail button within the GridView.

Any ideas to do this?

Something like this is not working:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<FOO>" %>
<%
Html.DevExpress().GridView(settings =>
{
    settings.Name = "resultsTable";
    settings.KeyFieldName = "ResultId";
    settings.CallbackRouteValues = new { Controller = "Results", Action = "ResultsPartial" };
    settings.Width = Unit.Percentage(100);
    settings.Height = Unit.Percentage(100);

    //...

    settings.PreRender = (sender, e) =>
    {
        MVCxGridView grid = (MVCxGridView)sender;
        grid.DetailRowGetButtonVisibility += (s_, e_) =>
        {
            if (some_condition == true)
            e_.ButtonState = GridViewDetailRowButtonState.Hidden;
        };
    };
})
.Bind(Model.Results)
.Render();

我想我会在 SetDataItemTemplateContent 中使用纯 html 按钮。

我做了类似的事情，使用可以扩展的简单 if 来处理链接的输出。我想它也应该适合你。

var linkWeb = settings.Columns.Add("", "Web");
linkWeb.SetDataItemTemplateContent(c =>
{
   DevExpressHelper.WriteLineToResponse((DataBinder.Eval(c.DataItem, "UrlWeb") != null && DataBinder.Eval(c.DataItem, "UrlWeb") != "") ? "<a href=\"" + DataBinder.Eval(c.DataItem, "UrlWeb") + "\" target=\"_blank\" title=\"Url\"><img src=\"" + Url.Content("~/content/img/url.png") + "\" alt=\"Url\" /></a>" : "");
});

在此 html 代码中，您可以附加对所需回调操作的调用。如果我没记错的话，应该是这样的

mygrid.UpdateEdit();

希望有帮助。

I think I will go with pure html button inside the SetDataItemTemplateContent.

I did something like that to handle the output of a link using a simple if that you can extend. I guess it should work also for you.

var linkWeb = settings.Columns.Add("", "Web");
linkWeb.SetDataItemTemplateContent(c =>
{
   DevExpressHelper.WriteLineToResponse((DataBinder.Eval(c.DataItem, "UrlWeb") != null && DataBinder.Eval(c.DataItem, "UrlWeb") != "") ? "<a href=\"" + DataBinder.Eval(c.DataItem, "UrlWeb") + "\" target=\"_blank\" title=\"Url\"><img src=\"" + Url.Content("~/content/img/url.png") + "\" alt=\"Url\" /></a>" : "");
});

Inside this html code you could attach a call to the callback action you need. If i remember right, it should be something like that
