telerik scheduler timeline view render problem

if you are using Telerik RadScheduler TimelineView,

<TimelineView

        UserSelectable="false"

        GroupBy="Room"

        GroupingDirection="Vertical"

        ColumnHeaderDateFormat="dd"

        HeaderDateFormat="M"

        SlotDuration="12:00:00"

        TimeLabelSpan="2"

        ShowInsertArea="false"></TimelineView>

TimeLabelSpan property gives you some trouble such as alignment problems. to solve the issue, set the code snippet to your css file.

.rsHidden { display:table-row !important;}

Telerik RadWindow Set Behaviors Client Side

//this is radbutton onclientclicking event
function openWindow(sender, args) {
 
    //create window
    var parentPage = GetRadWindow().BrowserWindow;

    //open window

    //set properties
    win.setSize(400, 600);
    win.setTitle("ActionLogs Window");
    win.setActive();
    win.setModal(true);

//set behaviors
    win.set_behaviors(winBehaviours.Close | winBehaviours.Move);

    //prevent postback
    args.set_cancel(true);

}


var winBehaviours = {

    None: 0,
    Resize: 1,
    Minimize: 2,
    Close: 4,
    Pin: 8,
    Maximize: 16,
    Move: 32,
    Reload: 64
}


function GetRadWindow() {
    var oWindow = null;
    if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
    else if (window.frameElement && window.frameElement.radWindow) oWindow = window.frameElement.radWindow;//IE (and Moz az well)
    return oWindow;

subdomain HttpContext.Current.Server.MapPath Problem

const String folderName = "App_Data/Database"; not works 
const String folderName = "~/App_Data/Database"; works

Unable to update the EntitySet '' because it has a DefiningQuery and no element exists in the element to support the current operation.

To be able to solve the problem, add the Primary Key to the table
Refresh the entity model.

Create Image Thumb Name

if file name contains in path, no problem.


 String CreateThumbName(String fullPath)

        {
            //get file name
            var onlyFilename = System.IO.Path.GetFileNameWithoutExtension(fullPath);
            //name with extension
            var nameWithExt = System.IO.Path.GetFileName(fullPath);
            //just extension
            var ext = System.IO.Path.GetExtension(fullPath);
            //create thumb name
            var thumbName = String.Format("{0}_thumb{1}", onlyFilename, ext);
            //replace file name with thumb name
            var result = fullPath.Replace(nameWithExt, thumbName);
           
            //return result
            return result;
        }

Sample

var fullPath = "c:\windows\MyFolder\my.jpg"
var result = CreateThumbName(fullPath);

Console.WriteLine(result);

Output

c:\windows\MyFolder\my_thumb.jpg

Asp.net Convert AbsolutePath to RelativePath

I wrote step by step to be clear. use this method as extension could be nice.

 String ToRelative(String absolute)
        {
            //getting root portion
            var root = HttpContext.Current.Server.MapPath("/");
            //removing root portion
            var result = absolute.Replace(root, "");
            //replace backslash-spash
            result = result.Replace("\\", "/");
            //finalize the path adding first char as slash
            result = String.Format("/{0}", result);
            //good to go
            return result;
        }

WCF Json Service Method Argument null Problem

Do NOT use "url" as a argument name.

Wcf Service Method

 [OperationContract]
 [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json,
         RequestFormat= WebMessageFormat.Json)]
PageDTO PageByUrl(String url,String language);  --> PageDTO PageByUrl(String title,String language); 


-----------------------------------------------------------------------

Requested Url:

http://localhost:2222/tr-TR/test-page-1
-----------------------------------------------------------------------

Jquery Ajax Call

<script type="text/javascript">

    $(document).ready(function () {
     
        data = window.location.pathname.split("/");
        urlStr = data[data.length -1];
        languateStr = data[data.length - 2];

        var data = new Object();
        data.url = urlStr;   ---> data.title=urlStr;
        data.language = languateStr;

        //var xxx = $.toJSON(data);
        //result: {"url":" test-page-1","language":"tr-TR"}

        caller_dynamic(data);

    });

    var menuUrl = "http://localhost:9000/PublicService.svc/PageByUrl";

    function caller_dynamic(mydata) {

        $.support.cors = true;

        $.ajax({

            type: "POST",

            url: menuUrl,

            contentType: "application/json; charset=utf-8",

            dataType: "json",

            data: $.toJSON(mydata),

            success: function (data) {

                $("#content").html(data.Content);

            },

            error: function (xhr) {

                alert(xhr.responseText);

            }

        });

    }

     < /script>

---------------------------------------------------------------------

public PageDTO PageByUrl(String url, String language) --> (String title, String language)

        {

            try

            {

                var publicBS = unityContainer.Resolve();

                var page = publicBS.PageByUrl(title);

                return page;

            }

            catch (Exception ex)

            {

                throw DynFaultException.Instance.CreateFault(ex);

            }

        }

Conclusion

if url is null, do NOT panic. just change the name of the argument name url to title.

Javascript Page Document ready, PageLoad, Application Init

$(document).ready()

• Ideal for onetime initialization.
• Optimization black magic; may run slightly earlier than pageLoad().
• Does not re-attach functionality to elements affected by partial postbacks.

pageLoad()

• Unsuitable for onetime initialization if used with UpdatePanels.
• Slightly less optimized in some browsers, but consistent.
• Perfect for re-attaching functionality to elements within UpdatePanels.

Application.Init

• Useful for onetime initialization if only ASP.NET AJAX is available.
• More work required to wire the event up.
• Exposes you to the “sys is undefined” error if you aren’t careful.

LINQ group by Count and Avarage/avg

var query = from q in this.context.TRAINING_PLAYER
                        group q by q.session_id into grp
                        select new
                        {
                            sessionId = grp.Key,
                            count = grp.Select(p => p.player_id).Distinct().Count()

ASP.NET JSON Serialization and Deserialization

You should reference the Assembly System.Web.Extensions.dll, v4.0.30319

Serialize

JavaScriptSerializer js = new JavaScriptSerializer();

MyClass c = new MyClass();

c.Name = "Tugbay";

c.BirthDate = 1981;

String serializedString = js.Serialize(c);

Result

{"Name":"Tugbay","BirthDate":"1981"}

---

Deserialize

JavaScriptSerializer js = new JavaScriptSerializer();

var instance = js.Deserialize(serializedString);

Console.WriteLine("Name:" + instance.Name);

Console.WriteLine("BirthDate:" + instance.BirthDate);

Result

Name: Tugbay
BirthDate: 1981

Asp.Net Routing is not working

add the below code snipped to the web.config

   < system.webServer>
     < modules runAllManagedModulesForAllRequests="true"/>
   < /system.webServer>

AND also


in the global.asax fıle, find the Application_Start(object sender, EventArgs e) event, add the code to the event.

        protected void Application_Start(object sender, EventArgs e)

        {

            routes.Ignore("{resource}.axd/{*pathInfo}");
            routes.Ignore("{*alljs}", new { alljs = @".*\.js(/.*)?" });
            routes.Ignore("{*allcss}", new { allcss = @".*\.css(/.*)?" });
            routes.Ignore("{*allpng}", new { allpng = @".*\.png(/.*)?" });
            routes.Ignore("{*allgif}", new { allgif = @".*\.gif(/.*)?" });
            routes.Ignore("{*alljpg}", new { alljpg = @".*\.jpg(/.*)?" });
            routes.Ignore("{*allbmp}", new { allbmp = @".*\.bmp(/.*)?" });

            RegisterRoutes(RouteTable.Routes);
            RouteTable.Routes.Add("about-browse", new Route("aboutus", new PageRouteHandler("~/About.aspx")));
