Solution 5

Hi, I hope you don't have insert/update code in txtIsPaid_CheckedChanged event

so please declare the object empleave at the top of page_load event (EmployeeLeave empleave = new EmployeeLeave();), and use this object in all events.

and change txtIsPaid_CheckedChanged envent like this

C#

EmployeeLeave empleave = new EmployeeLeave();

protected void Page_Load(object sender, EventArgs e)
{
      /// code
}

protected void txtIsPaid_CheckedChanged(object sender, EventArgs e)
{
      empleave.IsPaid = txtIsPaid.Checked;
}

please update, good luck,

bro i have solved it thanx

Solution 1

Dont Convert txtIsPaid to bool.
Directly set

C#

empleave.IsPaid =  true;

it will take the value bit in DB

i tried your solution but still same result

Solution 2

HI,

why are you converting string (txtIsPaid.Text) in boolean. It will not work.

you can do this, if check box is checked then just pass true to database like,

C#

protected void txtIsPaid_CheckedChanged(object sender, EventArgs e)
        {
            if (txtIsPaid.Checked == true)
            {
                EmployeeLeave empleave = new EmployeeLeave();
                empleave.IsPaid = true;
            }
            else
            {
                EmployeeLeave empleave = new EmployeeLeave();
                empleave.IsPaid = false;
            }
        }

If this will also not work then pass 1 instead of true and 0 instead of false.

Why I am downvoted , is the code is not understandable or something else ??

Gihan Liyanage · Accepted Answer · 2014-09-30T23:09:00

Your first Mistake is Naming, Dont use txt for Check Boxes. Search about naming user controls.
Click Here[^]

Then you already had a condition for check the status of check box

C#

if (txtIsPaid.Checked == true)
            {
}

, and you are passing the value of check box text. You should pass the current status of the check box.

Correct the code as follows. But be sure to have good names, not txtIsPaid.And also empleave.IsPaid should be a bool variable.

C#

protected void txtIsPaid_CheckedChanged(object sender, EventArgs e)
        {
            if (txtIsPaid.Checked == true)
            {
                EmployeeLeave empleave = new EmployeeLeave();
                empleave.IsPaid = true;
            }
            else
            {
                EmployeeLeave empleave = new EmployeeLeave();
                empleave.IsPaid = false;
            }
        }
