获取表单值与MvcPager [英] Getting form values with MvcPager

问题描述

当我选择我的 PagedList中任何页面; T＆GT; 的 [HTTPGET] 方法被激活。正因为如此，我不是能够使用 Request.Form.GetValues​​（）。

When I select any page of my PagedList<T> the [HttpGet]method is activated. Because of this, Im not able to use Request.Form.GetValues().

我刚才看到的请求变量到即时窗口，并意识到，我没有看到，我从我有（请求的ID想要的任何值不给我任何屏幕的任何ID值，因为我不是使用POST方法）。

I just saw the Requestvariable into the immediate window and realized that I dont see any value that I want from the IDs that I have ( the request dont bring me any value of any ID of the screen, since Im not using the post method).

我得到了一个网格（表），每个记录是一个复选框，分页后，我需要知道至极复选框中的一个字段被启用，以保持它选中（我已经取得了code，以保持它的检查，我只需要知道如何林去看看，如果这些复选框被选中。

I got a grid (table) and one field of each record is a checkbox, after the pagination, I need know wich checkbox is enabled to keep it checked ( I already made the code to keep it checked, I just need to know how Im going to see if those checkboxes are checked.

我已经知道自己的身份证了。

I already know their ID too.

即时通讯使用下列控制生成的复选框：

Im using the following control to generate those checkboxes:

//foreachloop 
<%: Html.CheckBox(item.ID.ToString(), item.isChecked)%>

有关我的分页，进出口使用下列内容：

For my pagination, Im using the following:

.aspx的：
    ＆LT;％：Html.Pager（Model.ListaGridPaginada）％>

Aspx: <%: Html.Pager(Model.ListaGridPaginada)%>

这是寻呼机调用以下超负荷：

This pager is a overload that calls the following:

public static MvcHtmlString Pager(this HtmlHelper helper, int totalPageCount, int pageIndex, string actionName, string controllerName, 
        PagerOptions pagerOptions, string routeName, RouteValueDictionary routeValues, IDictionary<string, object> htmlAttributes)
    {
        var builder = new PagerBuilder
            (
                helper,
                actionName,
                controllerName,
                totalPageCount,
                pageIndex,
                pagerOptions,
                routeName,
                routeValues,
                htmlAttributes
            );
        return builder.RenderPager();
    }

我调用该方法至极构建这个变量具有以下参数：

I call the method wich constructs this variable with the following parameters:

public static MvcHtmlString Pager<T>(this HtmlHelper helper, PagedList<T> pagedList)
    {
        if (pagedList == null)
            return Pager(helper,null, null);
        return Pager(helper, pagedList.TotalPageCount, pagedList.CurrentPageIndex, null, null, null,null, null,null);
    }

这pagerHelper是 Webdiyer

This pagerHelper is from Webdiyer

推荐答案

我觉得如果你把它包装的形式，并设置为GET方法，那么它应该通过在所有的表单值进入查询字符串。事情是这样的：

I think if you wrap it in a form and you set the method to GET, then it should pass in all of your form values into the query string. Something like this:

using (Html.BeginForm("Controller", "Action", FormMethod.Get))
{
    // grid in here
    //foreachloop 
    <%: Html.CheckBox(item.ID.ToString(), item.isChecked)%>
    <input type="submit" value="Save" />
}

当你点击提交按钮，您的查询字符串会是这个样子：

When you click the submit button, your query string will look something like this:

Action?ID1=false&ID2=true&ID2=false

其中，你将看到查询字符串，以确定是否该复选框ID包含如此。见ID1如何=假，但是ID2是真假？这意味着ID1是不加制止，但被ID2检查。

Which, you'll look at the query string to determine if the checkbox ID contains true. See how ID1=false, but ID2 is true and false? That means ID1 was unchecked, but ID2 was checked.

Request.QueryString["ID2"].Contains("True")

如果不适合你，你可以跟踪哪些复选框被把他们选中状态在一个隐藏的价值，并通过周围使用javascript检查。

If that doesn't work for you, you could keep track of which checkboxes are checked with javascript by putting their checked state in a hidden value and passing that around.

这是否帮助任何？
