easy login mechanism for demo purposes

When you need to prepare a quick demo for a few users and you have not implemented your login mechanism yet, you can easily add forms authentication to you asp.net web application.

a simple login form (.aspx file)

<p>

        <asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">Username:</asp:Label>

        <asp:TextBox ID="UserName" runat="server" CssClass="textEntry"></asp:TextBox>

    </p>

    <p>

        <asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">Password:</asp:Label>

        <asp:TextBox ID="Password" runat="server" CssClass="passwordEntry" TextMode="Password"></asp:TextBox>

    </p>

server side (aspx.cs file):

         protected void Page_Load(object sender, EventArgs e)

        {

            if (FormsAuthentication.Authenticate(this.UserName.Text, this.Password.Text))

            {

                FormsAuthentication.RedirectFromLoginPage(this.UserName.Text, true);

            }

        }

add the following lines to web.config file:

     <authentication mode="Forms">

      <forms loginUrl="~/menu/Login.aspx"  defaultUrl="~/menu/MenuMyApp.aspx" timeout="2880" cookieless="AutoDetect">

        <credentials passwordFormat="Clear">

          <user name="demo1" password="1"/>

          <user name="demo2" password="2"/>

        </credentials>

      </forms>

    </authentication>

    <authorization>

      <deny users="?"/>

    </authorization>

Your demo app is secure now.. Demo users can only login with the credentials specified.

how to telerik:RadMenu show path

In order to view the selected path from your telerik RadMenu as in the picture below, you can use the following code:

aspx code:


<telerik:RadSiteMap ID="BreadCrumbSiteMap" runat="server" DataTextField="Text" DataNavigateUrlField="NavigateUrl">
        <DefaultLevelSettings ListLayout-RepeatDirection="Horizontal" SeparatorText="/" Layout="Flow" />
</telerik:RadSiteMap>



csharp code:


      protected void Page_Load(object sender, EventArgs e)
        {
            RadMenuItem currentItem = RadMenu.FindItemByUrl(Request.Url.PathAndQuery);
            if (currentItem != null)
            {
                currentItem.HighlightPath();
                DataBindBreadCrumbSiteMap(currentItem);
            }
            else
                RadMenu.Items[0].HighlightPath();
        }

        private void DataBindBreadCrumbSiteMap(RadMenuItem currentItem)
        {
            List breadCrumbPath = new List();
            while (currentItem != null)
            {
                breadCrumbPath.Insert(0, currentItem);
                currentItem = currentItem.Owner as RadMenuItem;
            }
            BreadCrumbSiteMap.DataSource = breadCrumbPath;
            BreadCrumbSiteMap.DataBind();
        }

using Telerik Scheduler to view weekly lesson plan

In this post, i present the code that configures Telerik radscheduler to view a weekly lesson plan. In order to do this, the selected date attribute should be a month starting at Monday (which is the first week day in the scheduler.)

.aspx code (actually i use it as a user control )

<telerik:RadScheduler runat="server" ID="RadScheduler" Width="750px" SelectedView="WeekView"

    TimeZoneOffset="00:00:00" SelectedDate="2013-04-01" DayStartTime="07:00:00" DayEndTime="23:59:00"

     ReadOnly="true"

     DataEndField="End" 

     DataKeyField="DersProgramiID" DataStartField="Start" DataSubjectField="DersItem" 

     AllowDelete="False" AllowEdit="False" AllowInsert="False" 

     DayView-DayStartTime="07:00:00" DayView-DayEndTime="23:59:00" LastDayOfWeek="Sunday" 

     WeekView-DayEndTime="23:59:00" WeekView-DayStartTime="07:00:00" WeekView-WorkDayEndTime="23:59:00" 

     WeekView-WorkDayStartTime="07:00:00" WorkDayEndTime="23:59:00" WorkDayStartTime="07:00:00" FirstDayOfWeek="Monday" 

     Height="900px" ShowNavigationPane="True" ShowAllDayRow="False" ShowHeader="False" ShowFullTime="False" ShowFooter="False" HoursPanelTimeFormat="HH:mm">

    <TimelineView UserSelectable="false" ShowDateHeaders="false"></TimelineView>

    <TimeSlotContextMenuSettings EnableDefault="true"></TimeSlotContextMenuSettings>

    <AppointmentContextMenuSettings EnableDefault="true"></AppointmentContextMenuSettings>

</telerik:RadScheduler>

csharp code to fill the scheduler:

 public void fill(List list)

 {

      this.RadScheduler.DataSource = list;

      this.RadScheduler.DataBind();

  }

The weekly lesson plan is as follows:

introduction to telerik reports

it has been years since i have not dealt with reporting.. so, i am a total newbie for this..
in this post, i share my one-day activity on warming up using telerik reports, a sample telerik report about a specific user's information viewed in a web app and how to deploy it in a remote server..
first thinngs first.. my bookmarks:

• http://tv.telerik.com/search?&keywords=reporting -> all videos about telerik reports 
• http://tv.telerik.com/watch/reporting/webinar/telerik-reporting-101 -> a startup webinar by Kevin Babcock.. the webinar pretty much follows the totorial on http://www.telerik.com/support/documentation-and-tutorials/step-by-step-tutorial-for-reporting.aspx. i recommend to watch the webinar, it is easier to understand..
• http://tv.telerik.com/watch/reporting/webinar/falafelreportingwebinar -> another startup webinar.. i have not watched this yet, but i am planning to do so..
• http://tv.telerik.com/watch/reporting/video/telerik-trainer-reporting-parameters -> about report parameters. good demos..
• http://tv.telerik.com/watch/reporting/sqldatasource/using-parameterized-queries-telerik-reporting-with-sqldatasource-component and http://tv.telerik.com/watch/reporting/video/telerik-reporting-design-time-support-for-parameterized-queries -> these two videos are actually for my specific needs.. producing a report by passing the user id from the hosting web app.. 

Report library part:

Now, the first step is creating a report library project.. Then a telerik report is created. i used the report wizard and used an SqlDataSource as the data source. My select query contains a parameter:

SELECT ...

FROM  ...  

WHERE TableStudent.ID = @StudentID

The report also contains a parameter with the same name. 

The constructor for the report is something like that:

        public ReportStudent(int studentID)

        {

            InitializeComponent();

            this.ReportParameters["StudentID"].Value = studentID;

            this.StudentDataSource.Parameters[0].Value = studentID;

            this.StudentDataSource.SelectCommand =           this.StudentDataSource.SelectCommand.Replace("@StudentID", studentID.ToString());

        }

Web app part:

In the web app which is going to view the report, i added a report viewer from the toolbox, but left the report property unassigned.  In the web page, the user selects a student, then presses a button and the report for the selected student is viewed inside the report viewer.

The button click event code is as follows:

protected void ButtonReport_Click(object sender, EventArgs e)

        {

            if (Session["StudentID"] != null &&

                !(((string)Session["StudentID"]).Trim().Equals("")))

            {

                ReportViewer viewer = (ReportViewer)this.ReportContent.Controls[0];

                ReportStudent report = new ReportStudent(Int32.Parse((string)Session["StudentID"]));

                viewer.Report = report;

                viewer.RefreshReport();

            }

        }

The above scenario works perfectly..

When deploying to the remote server, change the connection strings accoringly in:

• Web.config of web app
• Settings.settings and app.config for the report library.

Besides,  add the telerik libraries shown in the figure. (By the way, i am not sure if this list is minimal or not...)

and finally, here is telerik relevant portions of my web.config:
