How to bind data in jqgrid in Asp.net(C#)


Here I will explain how to bind data in jqgrid. First of all create a Table for save the data and then after stored procedure for retrive data from table.
 

CREATE TABLE [dbo].[Student](
	[StudentID] [int] IDENTITY(1,1) NOT NULL,
	[FirstName] [nvarchar](50) NULL,
	[LastName] [nvarchar](50) NULL,
	[Standard] [int] NULL,
	[Division] [nvarchar](5) NULL,
	[Address] [nvarchar](500) NULL,
	[Mobileno] [varchar](20) NULL,
 CONSTRAINT [PK__Student__32C52A795B736AEC] PRIMARY KEY CLUSTERED 
(
	[StudentID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]




CREATE PROCEDURE [dbo].[WB_Fill_StudentInfo] 
AS
BEGIN
	-- SET NOCOUNT ON added to prevent extra result sets from
	-- interfering with SELECT statements.
	SET NOCOUNT ON;

  SELECT * FROM Student ORDER BY StudentID
END 

In this code snippest i will set cell color conditionally, Open fancybox popup, Display Image and also add checkbox selection.

            }
        }
    }
}


When the json data length is increse then it gives error so here I will set maxJsonLength in webconfig.

<configuration>
<system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="50000000"/>
      </webServices>
    </scripting>
  </system.web.extensions>
</configuration>

Generating serial numbers and keys in Asp.net(C#).

here we are using GUID for generate serial numbers and GUID is always unique. Example format: XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX. Guid SerialKeyGuid = Guid.NewGuid(); string AccessKey = SerialKeyGuid.ToString("N"); string AccessKeyLength = AccessKey.Substring(0, 28).ToUpper(); char[] serialArray = AccessKeyLength.ToCharArray(); string SerialNumber = ""; int P = 0; for (int B = 0; B < 28; B++) {                 for (P = B; P < 4 + B; P++)                 {                     SerialNumber += serialArray[P];                 }                 if (P == 28)                 {                     break;                 }         ...

How to write Unit Tests in .net

Unit tests are automated tests that verify the behavior code like methods and functions. Writing unit tests is crucial to clean coding, as they help ensure your code works as intended and catches bugs early in the development process. I can share some tips for writing effective unit tests: Write tests for all public methods Every public method in your code should have a corresponding unit test. This helps ensure that your code behaves correctly and catches any unexpected behavior early. public class Calculator { public int Add(int a, int b) { return a + b; } } [TestClass] public class CalculatorTests { [TestMethod] public void Add_ShouldReturnCorrectSum() { // Arrange Calculator calculator = new Calculator(); int a = 1; int b = 2; // Act int result = calculator.Add(a, b); // Assert Assert.AreEqual(3, result); } } Test boundary conditions  Make sure to test boundary conditions, such a...
