我创建了自己的扩展程序:
public static MvcHtmlString hSearch(this HtmlHelper helper, string labelName, string labelCaption, string textName, string textValue, string tableName, string buttonId,
string actionName, string controllerName, object routeValues, object htmlAttributes)
{
var textbuilder = new TagBuilder("input");
textbuilder.MergeAttribute("id", textName);
textbuilder.MergeAttribute("name", textName);
textbuilder.MergeAttribute("value", textValue);
textbuilder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
ModelMetadata metadata = ModelMetadata.FromStringExpression(labelName, helper.ViewData);
String innerText = labelCaption ?? (metadata.DisplayName ?? (metadata.PropertyName ?? labelName.Split('.').Last()));
if (String.IsNullOrEmpty(innerText))
{
return MvcHtmlString.Empty;
}
TagBuilder labelbuilder = new TagBuilder("label");
labelbuilder.Attributes.Add("for", TagBuilder.CreateSanitizedId(helper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(labelName)));
labelbuilder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
labelbuilder.SetInnerText(innerText);
//return new MvcHtmlString(textbuilder.ToString());
var buttonBuilder = new TagBuilder("button");
buttonBuilder.MergeAttribute("id", buttonId);
buttonBuilder.SetInnerText(buttonId);
var formBuilder = new TagBuilder("form");
var urlHelper = new UrlHelper(helper.ViewContext.RequestContext);
formBuilder.Attributes.Add("action", urlHelper.Action(actionName, controllerName, routeValues));
formBuilder.Attributes.Add("method", "Post");
formBuilder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
formBuilder.InnerHtml = labelbuilder.ToString() + textbuilder.ToString() + buttonBuilder.ToString();
return new MvcHtmlString(formBuilder.ToString());
}
我在视图中使用了扩展:
@Html.hSearch("lblSrch", "Company", "companyName", (string)TempData["cName"], "CHComp", "Search", "Fetch", "Home", null, null)
现在我想在单击按钮时将 tableName 传递给控制器。我的控制器如下所示:
public ActionResult Fetch(string search, string tablename)
{
var c = cbo.fetchData(search, tablename);
return PartialView(c.ToList());
}
等待回复。。谢谢。。
