LinearGradientBrush in XAML Silverlight


Introduction

In Silverlight, LinearGradientBrush paints area with a gradient. A linear gradient defines a gradient along a line. The line’s end point is defined by the Start and End points properties of the linear gradient. LinearGradientBrush paints these stops along this line.


Working on LinearGradientBrush by hand is very tedious job especially when we have many colors. Here color picker will be very useful. Let’s talk how to work with this.

To work with color picker, select the third tab allows to visually editing gradient brushes. The gradient brush editor fully based on GradientStop slider. Look at below:


In above image, we have used 5 stopper and each has different color gradient. Stopper location is known as Offset point. Offset value always varies between 0 to 1. Each stopper has offset value which locates the position on slider.


By using marked point (red circle) we can reverse the gradient stopper. By using marked point (blue circle) we can convert the brush in radial or linear form. If you wish to change the gradient color of any point (stopper) then select the stopper first and then pick the color.

We can inset the new stopper in slider by just clicking on slider and even we can delete the stopper by dragging the stopper icon.

If we unhide the advanced properties of brushes then we will find some more stuffs. Look at image below:


In above image,

StartPoint

This gets or sets the two dimensional coordinates for the start point of the linear gradient.

EndPoint

This gets or sets the two dimensional coordinates for the end point of the linear gradient.

MappingMode

This gets or sets the value that specifies whether the gradient brush positioning coordinates are absolute or relative to the output area.

SpreadMethod

This gets or sets the type of spread method that specifies how to drag a gradient that starts of ends inside the bounds of the object to be painted.

Opacity

This is very useful option by which we can get or set the opacity of the brush.


Above icons are very useful, by which we can make transformation in brush. This will create an interesting color output in our art.

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.

Customize User's Profile in ASP.NET Identity System

Image
Note: You should read this post instead, I found below walkthrough will not work on ASP.NET Identity 2. I will re-work on this post soon. In this post you will learn how to customize User’s Profile and add some more fields like FirstName, LastName, EmailID etc with ASP.NET Identity System. In my last post I listed some of the great new features introduced with Identity system .

Lambda two tables and three tables inner join code samples

In this blog post you will learn inner join using lambda queries. There will be two samples, in first sample you will see how you can join two tables and in second sample you will see how you can extend even further to join three tables and so on. I will sample in-memory data, but the same implementation will work with IQueryable (lazy query) too. Here's the code snippet:- namespace ConsoleApp1 {     class Program     {         static void Main()         {             var table1 = new List<Table1>();             table1.Add( new Table1 { Id = 1, Name = "Name 1" , Address = "Address 1" });             table1.Add( new Table1 { Id = 2, Name = "Name 2" , Address = "Address 2" });             table1.Add( new Table1 { Id = 3, Name = "Name 3" , Address = "Address 3" });             table1.Add( new Table1 { Id = 4, Name = "Name 4" , Address = "Address 4" });
