    [CLOSED] Calling Web API and accessing page serialized fields

    Hi,
    I want to access some page all fields values inside an ASP.NET Web API method as Dictionary, please guide how to achieve that, I want to implement a general purpose code so that ASP.NET Web API should be able to read all fields values passed from client-side as JSON on HttpRequest. This is what I have done so far but the service cannot read any field values of the page. Please guide Thanks

    ASP.NET Web API controller for service myService:
            [ActionName("Test")]
        [AcceptVerbs("POST", "GET")]
        public string Test(HttpRequestMessage requestMessage)
        {
            var values = requestMessage.Content.ReadAsAsync<Dictionary<string, string>>().Result;
            return string.Join(",", values.Values.Select(x => x));
        }
    ASP.NET Page declaration:
    
<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <ext:ResourceManager ID="ResourceManager1" runat="server">
        </ext:ResourceManager>
        <div>
            <ext:TextField runat="server" ID="txtName" FieldLabel="Name"  />
            <ext:TextField runat="server" ID="txtEmail" FieldLabel="Email"  />
            <ext:Button ID="btnSave" runat="server" Text="Save">
                <DirectEvents>
                    <Click
                        Success="console.log(result);"
                        Url="/api/myService/Test"
                        Type="Load"
                        Method="POST"
                        CleanRequest="true"
                        Json="true">
                    </Click>
                </DirectEvents>
            </ext:Button>
        </div>
    </form>
</body>
</html>

    Hi @VSPL,

    Please try to remove Type="Load". Does it help?

    Too long Querystring error

    Hi Daniil,
    Removing "Type = Load" creates big query-string which results this error:

    HTTP Error 404.15 - Not Found
    The request filtering module is configured to deny a request where the query string is too long.
    Please suggest, we are also trying to write our own method to achieve this like:
    var serializeControlValues = function () {
                // App is object
                // Convert object to array
                var arrControls = Object.keys(App).map(function(k) { return App[k] });

                // Filter array and convert to object for json
                var arrControlsByXType = arrControls.filter(filterType);
                var objControlWithValue = {};
                for (var i = 0; i < arrControlsByXType.length; i++) {
                    var cnt=arrControlsByXType[i];
                    if(cnt.xtype=="checkboxfield"){
                        objControlWithValue[cnt.boxLabel]=cnt.value;
                    }else{
                        objControlWithValue[cnt.fieldLabel]=cnt.value;
                    }
                }
                //console.log(JSON.stringify(objControlWithValue));

                return JSON.stringify(objControlWithValue);
            };
    And then passing the value return from this function as extra-parameter to our web-api controller method. But instead of writing our own, I want to do it with some native functionalities provided in Ext.Js / Ext.Net, please advise.

    Okay, I need to investigate in details. Could you, please, provide a simple test project to reproduce the problem?

    We have changed our requirement

    Hi Daniil,
    I have changed our approach now instead of calling web api, we have directly calling the direct event so that I can easily get the control values automatically, basically I wanted a general purpose handler in web api which was not working, further I wanted to publish a bus in from web-api method even that also not working, so I ended up placing a global event handler of a button click in my base page which will be execute for all child pages I just need to make sure that button should refer to correct base page event handler name. That will serve our purpose and you may close this thread. Thanks
