I need to create the confirm box in mvc controller?. Using this 'yes' or 'no' value I need to perform the action in my controller. How we do that?
Sample code:
public ActionResult ActionName(passing value)
{
// some code
message box here
if (true)
{ true code}
else { else code}
}
You can do this with ActionLink
@Html.ActionLink(
"Delete",
"DeleteAction",
"Product",
new { confirm = true, other_parameter = "some_more_parameter" },
new { onclick = "return confirm('Do you really want to delete this product?')" })
If user confirm, then link parameter will pass to the controller action method.
public ActionResult DeleteAction(bool confirm, string other_parameter)
{
// if user confirm to delete then this action will fire
// and you can pass true value. If not, then it is already not confirmed.
return View();
}
Update
You can not show message box in controller side. But you can do this like following
public ActionResult ActionName(passing value)
{
// some code
message box here
if (true){ ViewBag.Status = true }
else { ViewBag.Status = false}
return View();
}
And view
<script type="text/javascript">
function() {
var status = '@ViewBag.Status';
if (status) {
alert("success");
} else {
alert("error");
}
}
</script>
But these all codes are not elegant way. This is solution of your scenerio.
