Rich Controls in ASP.NET


Introduction and Demonstration

These high-level custom controls provide rich user interface and functionality. This release of ASP.NET includes two rich controls: the Calendar control and the AdRotator control.

Control
Purpose
AdRotator
Displays different ad images and, when clicked, will navigate to the URL associated with that image. You can define the rotation schedule in an XML file.
Calendar
Displays a monthly calendar and lets the user select a date.


The simplified syntax of the rich controls is as follows:


<asp:adrotator id="MyAdRotator" advertisementfile="ads.xml"
   runat="server" />
 
<asp:calendar id="MyCalendar"
   showdayheader="true"
   todaydaystyle-backcolor="yellow"
   todaydaystyle-forecolor="blue"
   runat="server"/>

These controls can then be referenced programmatically with code fragments like:


MyAdRotator.KeywordFilter = "Nutshell"
Dim ShortDate As String
ShortDate = MyCalendar.TodaysDate.ToString("D")
MyLabel.Text = "Today is " & ShortDate

Index.aspx Page:

<%@ Page Language="vb" %>
<html>
<head>
   <title>Rich Control Example</title>
   <script runat="server">
      Sub Page_Load( )
         MyAdRotator.KeywordFilter = "Nutshell"
         Dim ShortDate As String
         ShortDate = MyCalendar.TodaysDate.ToString("D")
         MyLabel.Text = "Today is " & ShortDate
      End Sub
   </script>
</head>
<body>
   <h1>Rich Control Example</h1>
   <form runat="server">
      <asp:table id="MyTable"
         border="1"
         cellpadding="5"
         cellspacing="0"
         runat="server">
         <asp:tablerow runat="server">
            <asp:tablecell runat="server">
               AdRotator Control:
            </asp:tablecell>
            <asp:tablecell runat="server">
               <asp:adrotator id="MyAdRotator"
                  advertisementfile="ads.xml"
                  runat="server" />
            </asp:tablecell>
         </asp:tablerow>
         <asp:tablerow runat="server">
            <asp:tablecell runat="server">
               Calendar Control:
            </asp:tablecell>
            <asp:tablecell runat="server">
               <asp:calendar id="MyCalendar"
                  showdayheader="true"
                  todaydaystyle-backcolor="yellow"
                  todaydaystyle-forecolor="blue"
                  runat="server"/>
            </asp:tablecell>
         </asp:tablerow>
      </asp:table>
      <asp:label id="MyLabel" runat="server"/>
   </form>
</body>
</html>

Migrating database from ASP.NET Identity to ASP.NET Core Identity

Image
As you know ASP.NET Core Identity (table structure) is different from what we had earlier in ASP.NET Identity. Actually the identity system which we have today with .NET Core is very mature and continuously evolved be it ASP.NET Membership, ASP.NET Identity 1, ASP.NET Identity 2 and now ASP.NET Core Identity. Recently I had to migrate few application to ASP.NET Core and similar its identity database. Because the table schema is changed, i had to re-think and create migration script which I would like to share with you today. It is very simple and easy, just three step and I had everything ready: STEP 1 : Change name of existing tables STEP 2 : Create ASP.NET Core Identity tables STEP 3 : Migrate data from old tables (ASP.NET Identity) to new tables (ASP.NET Core Identity) Script:  https://gist.github.com/itorian/c699e8534b392a6c726ec66c48100072 You should also watch my video, where I demoed migration.
