Javascript alert

[Peter]

I need a popup alert after a post back.

1) user clicks on the submit button
2) Server side code runs and if the result is false I want to display a java
script alert("It did not work")

How to do I display a popup message after a postback ?

Thank You

Re: Javascript alert

Try to use
this.Page.Clien tScript.Registe rStartupScript

I recal it works with AJAX.

George's response is correct. Do you have something like this...?

protected void MyButton_Click( object sender, System.EventArg s e)
{
bool blnResult = <do server-side processing>;

if (!blnResult)
{
ClientScript.Re gisterStartupSc ript(GetType(), "failure", "alert('It
did not work');", true);
}
}

RE: Javascript alert

Hi Peter,

You can try this:

protected void Button1_Click(o bject sender, EventArgs e)
{
RegisterClientS criptBlock("tes t", "<script
type='text/javascript'>ale rt('hello world!')</script>");
}

Please let me know if it works.

No that does not work, I get no errors and no PopUp. If I put a break point
at the RegisterClientS criptBlock the process does stop there.

The popup does not work even if you have

if (1==1)
{
ClientScript.Re gisterStartupSc ript(GetType(), "failure", "alert('It
did not work');", true);
}


if I add 'ClientScript.R egisterStartupS cript(GetType() , "failure",
"alert('It did not work');", true);' in the Page_Load event it pops up only
when the page loads it never displays on PostBack

protected void Page_Load(objec t sender, EventArgs e)

{

ClientScript.Re gisterStartupSc ript(GetType(), "failure", "alert('It did
not work');", true);

}

See my previous reply..

You've got the code in the wrong place - it needs to go in the button's
OnClick (or OnCommand) event, not the Page_Load event...

Re: Javascript alert

uh....simply create a literal control in the end.
when you want to popup, change its text property to something like this.

LiteralControl1 .Text = "<script type='text/javascript'>win dow.open("it works
finally!")</script>"

There are really so many ways to get javascript work in asp.net!
I could even use Header and added an htmlgenericcont rol with similar text.

It's in OnClick event and it does not work, besides in Page_Load event,
I removed it from Page_Load event and still does not work.

Are you sure that it's actually being called? If you put a breakpoint on it
and click the button, does execution stop on the above line...?

Well, now I'm really puzzled!

If you continue execution and (when the page has been rendered) do a View
Source, do you see the above JavaScript alert in the page's rendered
output...?
