After user have logged in if he/she press the back button of internet browser, then he/she will back to login page. But if he/she then again press forward button of internet explorer then he/she should not get back to the page which he/she traversed before.
How is it possible?
It will be in asp.net 2.0.

This is how browsers works. You are seeing a cached preview of the page by browser. You need to check the session existence in the page_load. So when user clicks anywhere in the page after logging out, he/she will be thrown to login page.

Hi Friends
I am using Ajax in C#.NET.
I have recently noticed that. I cannot fire Messagebox(Javascript-JS) if inside Update Panel.
I am using Update Panel on my GridView.
Only click of Delete Button i am firing one JS asking "Are You Sure"
My Code
LinkButton l = (LinkButton)e.Row.FindControl("lbtnDelete");
l.Attributes.Add("onclick", "javascript:return " +
"confirm('Are You Sure You want to Delete ? ')");
The Above Code works perfectly. But then i make a DataBase Check if that Record is used anywhere else.
So its like
if(CheckRecord)
Response.Write("<script>alert('Are you sure youw want to Continue?')</script>");
It doesnt work.
i tired another dll for msgbox, which also doesnt work.
I suspected for the Update panel. And i was right. If i remove the Update Panel both the options fire MessageBox for me.
But i am using Edit,Delete,AddNew methods in GridView henceforth i need Update Panel.
Now i have no Idea what should i do?
Any solutions would be appreciated.
Thanks

Menon,
You cannot use Response.Write while using Microsoft AJAX, since the page will not postbacks fo your request. You can use Client Script of the Microsoft AJAX.
Add handler for endRequest like below,
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(CheckRecordCallBack);
CheckRecordCallBack(sender, arg){
if (args){
if (args.get_error()){
args.set_errorHandled(true);
alert(args.get_error().message);
}
}
}
You must throw the Message which you want to show after CheckRecord process from the CodeBehind.
For more reference, read http://www.asp.net/ajax/documentation/live/ClientReference/default.aspx[^]

I even found another solution for my question.
ScriptManager.RegisterStartupScript
This also works.
Thanks

I want to image verification on my user registration asp.net forum. And I must be check between entered user verification code and image. So I need store code which on the image. If user click the button so page is post back and stored code is null. In this case I must be use viewstate (or session variable).
My question is viewstate value maybe stolen by bot. So Is it reasonable using viewstate variable for this process?
Do you have any idea?
Best Regards...

I don't think so. Viewstate value can be tampered easily. So it's not recommended to keep sensitive information over there.

Ok, What is your recomendation?

Hi there,
We're getting ready to move onto ASP.NET 2 websites/webapps, and need some options on a reporting tool or controls that people use...
Don't want to use Crystal Reports due to their horrendous licensing fees, and have looked at DevExpress's XtraReports Suite and also ActiveReports by Data Dymanics, but can't decide
Any help greatly appreciated! We're (obviously!) looking for the best tool for the cheapest price.  
Cheers!

you can use Reportviewer..
|
|
|
|

Err yeah I suppose we could, but I thought it was lacking in features that other 3rd party controls have (but that could just be my ignorance, as I have no real experience of using it - would be happy to find out more though...)

You need to write all of this in javascript, because you want it to happen on the client side. There's nothing built in to do it. you can handle the data bound event of the checkboxlist to inject attributes on the control, which is how you would handle the click or check changed events in order to fire your scripts. Then, you can just keep track of the ids of items that have been clicked and which ones are checked in your script and show a message if a third is clicked on.

I think this will work for u.
Dim i As Integer
For Each item As ListItem In CheckBoxList1.Items
If item.Selected Then
i = i + 1
End If
Next
If i > 2 Then
lblmsg.Text = "Thanks"
Else
lblmsg.Text = "Please Select atleast two items"
End If
God is always with you.
