我有一个包含部分视图的视图,其中包含一个通过 ajax 进行页面的 WebGrid。但是,我无法让父视图了解 WebGrid 所在的页面。我想要完成的是:我在包含视图上有一个“创建”按钮,可以导航到新页面,但我希望它将当前页面 # 作为查询字符串参数传递给新页面,这样如果他们取消创建,原始视图将加载上一页,而不是默认加载第一页。
我看到的问题是,当部分视图的网格更新时,父视图的模型不会改变。而且,虽然我可以为 ajaxUpdateCallback 创建一个方法,但我还没有弄清楚如何告诉这个方法当前页面是什么。
我的代码的相关部分如下所示: 在父视图中:
<div id="divList">
@Html.Partial("_MatterList", Model) //This is where the grid is defined
</div>
<br/>
<div id="newSection">
<input type="button" value="New Matter" onclick="newMatter();"></input>
</div>
<script type="text/javascript">
var _Page; //I tried creating a javascript variable to hold the page, but can't get it to populate with anything but the default 1.
function newMatter()
{
var urlAction = "@Url.Action("Create", "Matter", new { area = "Admin" })";
var subclientid = $("#SubClientID > option:selected").attr("value"); //defined in a form not displayed here
var clientid = $("#ClientID > option:selected").attr("value");//defined in a form not displayed here
redirect(urlAction, clientid, subclientid);
}
function redirect(urlAction, clientid, subclientid) {
if(clientid > 0 || subclientid > 0 ) {
urlAction += "?";
}
if(clientid > 0) {
urlAction += "clientid=" + clientid;
if(subclientid > 0) {
urlAction += "&subclientid=" +subclientid;
}
}
//I want to be able to add page in here as well. a la &page=_Page
window.location = urlAction;
}
在 _MatterList 部分视图中:
<div id="matterListing">
@{
var grid = new WebGrid<Matter>(null, rowsPerPage: 10, canSort: false, defaultSort: "Name", ajaxUpdateContainerId: "matterListing",ajaxUpdateCallback:"afterUpdate");
grid.Bind(Model.Matters, rowCount: Model.TotalRows, autoSortAndPage: false);
@grid.GetHtml(
tableStyle: "table90",
alternatingRowStyle: "tableAltRows",
headerStyle: "tableHeaders",
columns: grid.Columns(
grid.Column(... //there are a lot of columns, removed them because not important to the problem.
)
)
}
<script type="text/javascript">
function afterUpdate() {
_Page = @Model.PageNumber; //I tried this but it only ever shows 1 because it evaluates when the page first loads. What I need is for it to dynamically get the correct page at execution time.
}
</script>
</div>
我在想,afterUpdate 方法需要使用当前页面的参数(即调用 afterUpdate(2) 而不是使用@Model.PageNumber),但我不知道如何强制 WebGrid 通过沿着回调。有没有人有这个问题的解决方案?
