Requirement:
Check the verified fields in contact and unverified fields should remain unchecked.
Store the values as flags in a database table column.
Solution: Use
bit-masking and store each flag as a bit in the 16-bit table column.
In Model: Define
bool properties for each flag.
Public class details
{
public bool EmailChked { get;
set; }
public bool OtherEmailChked { get;
set; }
public bool MobileChked { get;
set; }
public bool OtherMobilechked { get;
set; }
public
details()
{
this.EmailChked
= false;
this.OtherEmailChked
= false;
this.MobileChked
= false;
this.OtherMobilechked = false;
}
}
In your
FillData method in repository(model)
After
getting the value from the database table column compare and set:
if ((value & 1) > 0 )
{
ld.EmailChked = true;
}
if ((value & 2) > 0)
{
ld.MobileChked = true;
}
if ((value & 4) > 0)
{
ld.OtherMobilechked = true;
}
if ((value & 8) > 0)
{
ld.OtherEmailChked = true;
}
To
save the flag status updation, in
controller, in the POST action method
Use FormCollection
and get the checked/unchecked status(to see how to get the checked/unchecked
status from view to Controller, scroll down) and then pass the status to the
save method.
Int16 status = 0;
if
(form["ChkEmail"].Contains("true"))
{
status |= 1;
}
else
{
status &= ~1;
}
if
(form["ChkOtherEmail"].Contains("true"))
{
status |= 8;
}
else
{
status &= ~8;
}
if
(form["ChkMobile"].Contains("true"))
{
status |= 2;
}
else
{
status &= ~2;
}
if
(form["ChkOtherMobile"].Contains("true"))
{
status |= 4;
}
else
{
status &= ~4;
}
if
(ModelState.IsValid)
{
Repository.VerificationStatus(status,
id);
}
How to get the checked/unchecked
status from view to Controller:
Use the checkbox’s string “name” and bool “IsChecked” parameters
<div>@Html.CheckBox("ChEmail", Model.OtherEmailChked)</div>
<div>@Html.CheckBox("ChOtherEmail", Model.OtherEmailChked)</div>
<div>@Html.CheckBox("ChMobile", Model.MobileChked)</div>
<div>@Html.CheckBox("ChOtherMobile ", Model.OtherMobileChked)</div>
When
the FormCollection is passed to the controller each checkbox’s status can be
known using: form["keyName"].Contains("true")
