How can I UPDATE specific GridView columns based on a CheckBox in one column

Question

My GridView has an \"Active\" CheckBox, to indicate whether the record is active or not. It\'s just a flag, a bit value in the database.

I need to UPDATE the \"Activate

Answer 1

I need a Status column in database which contains 1,0 for representing Employee's Status "Active" and "Inactive" respectively. I want edit this record through front-end,having grid-view, and want to perform on GridView's update event, after clicking on Edit Button. I have a TemplateField having header-text "Status". I am unable to update changed value of checkbox.

Moreover, if will get checked or unchecked CheckBox on the basis of value stored in database, if it is 0 then CheckBox will be uncheked, otherwise will be checked. If user click on edit button, and then check or uncheck any Check-box, then on the basis of this, value should be updated in database.

DataBase:-

CREATE TABLE [dbo].[Employee](
    [Employee_ID] [int] IDENTITY(1,1) NOT NULL,
    [Employee_Name] [varchar](50) NULL,
    [Employee_Address] [varchar](100) NULL,
    [Emp_Status] [int] NULL,
PRIMARY KEY CLUSTERED 
(
    [Employee_ID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON

Code:

protected bool GetStatus(string str)
    {
        if (str=="1")
        {
            return true;
        }

        else
        {
            return false;
        }
    }

I am getting Error:- 

An exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll but was not handled in user code
