If you were to troubleshoot the compiler message, I suspect that you'd find that you are missing the enclosing parenthesis around the compound conditions of your if clause.

It is saying invalid expression &&. In c# is it && using for 'and' operator or I have to write like
If(!IsPostBack && !String.IsNullOrEmpty(Session["FirstName"]) && !String.IsNullOrEmpty(Session["LastName"]))
Not closing each condition. Even if I write like this another syntax error
|
|
|
|
|
Just use Session["something"] = textbox.text to put the value in a asession and use it on a different page

you can use this to refresh:
Response.AppendHeader("Refresh", "60;URL=Page.aspx");
or this
this might help you

If you open a child form with javascript you have a reference to the new window.
You can use this reference to reset the location of the child window, therefore refreshing it.
<script type="text/javascript">
var childWindow;
function openPop()
{
childWindow = window.open('HTMLPage2.htm','name','height=400,width=200');
}
function refreshPop()
{
childWindow.location = childWindow.location;
}
</script>

Following is the code i am using to alert the user to press ok or cancel in the c# code behind file
string str = "confirm('ok?');";<br />
ScriptManager.RegisterStartupScript(this, typeof(Page), "", str, true);
i know , i can do the same at the java script end , I am asking this because i am executing these lines in between the function .
Now my question is can i programatically check whether the ok button is clicked or the cancel button is clicked ?

So, this just gets run wen they page loads ? And you want to know where, what was pressed ? Why would you have a page reload so you can show a confirm dialog ?
Obviously, if you don't store the button result somewhere, your code behind is never going to know what it was.

OK, so you just didn't post all the code ?
The best way to pass a value back to your codebehind is to store it in a hidden field. Then yuo need to write the client side Id of the hidden field so you can access it from your script ( easy, seeing as you're spitting out your script from your code behind already )

First i am sorry for these cross questioning , But i don't believe it is a bad idea until the question gets resolved.
Is ur suggestion valid if i am not writing script in the html , i mean i am writing it in the code behind , can i still store the value in hidden field ? How ?

Why would it make any difference where the script comes from ? Either way, you need a server control, which is a hidden field, and you need to have the client side id of that control, in your script, so you can store a value in it.

Hi I wouldn't use the word Urgent, people tend not to reply to the post when you do this.
Im sure what you are posting has an answer on google somewhere its not that complicated, search for validating input lengths

Please don't say that. To you, it's urgent. To us, you're just another guy who is not willing to do any work, or use google.
You need to read some basics.
1 - C# does not run on the client side, it cannot show the user an alert
2 - javascript is what runs on the client. Doing this on the client is pretty trivial, often you need to write some code to pass the client side Id of your textbox through to your script, but in this case you will just write event handlers, and can pass the textbox through to your script using 'this'

Do you mean you want to catch the values of the textboxes when the button is clicked?
|
|
|
|
