jqgrid后台处理搜索

jqgrid后台处理搜索，

如果点击jqgrid自带的搜索，则向后台传递“_search”参数，和searchfield、searchoper、searchstring三个值。如下所示：

string _search = context.request.querystring["_search"];

if (_search == "true") {
    string searchfield = context.request.querystring["searchfield"];
    string searchoper = context.request.querystring["searchoper"];
    string searchstring = httpcontext.current.server.htmldecode(context.request.querystring["searchstring"]);

    if (searchstring != "") {

        switch (searchfield) {
        case "xqlx":
            break;
        case "tjrxm":
            break;
        case "tjrlxdh":
            break;

        default:

            break;
        }

    }

}
