Thanks for your reply; but it will only fire onclick function; it will not execute the next part of the code which has been written in the Sub..End Sub.

There is blue underline with "ScriptMode" saying "Type 'ScriptMode' is not defined.

Your core issue is that you are clueless. No, you cannot make a page cycle pause half way through to run some JS, then continue. Not possible. Anyone who thinks it might be, has no idea about ASP.NET. You can do a postback, or you can use AJAX. You need a seperate call between the code that runs before the alert, and the code that runs after.

for your case, try this Response.Write("<script language='javascript'>alert('Hello');</script>");

Thanks for your working reply; the only thing came new in the picture that now if the alert comes on the page; and i click on ok button of the alert; the font style of all the textboxes becomess bold; and if i click on back button of the browser; it always send me the alert message.

Baran M

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click If Trim(TextBox1.Text) = "" Or Val(TextBox1.Text) > Val(TextBox2.Text) Or Trim(TextBox2.Text) = "" Or Val(TextBox2.Text) < Val(TextBox1.Text) Then Response.Write("<script language='javascript'>alert('Wrong Roll Number Ranges');</script>") Exit Sub End If setreport() Dim ss As String ss = tablename & ".aspx?startrol=" & TextBox1.Text & "&endrol=" & TextBox2.Text If Response.IsClientConnected Then Server.Transfer(ss) End If End Sub

If you're doing homework, you should talk to your teacher. If you're teaching yourself, start with something more basic. If you are doing paid work, then you are a disgrace, you should tell your client that you're robbing them. If someone hired you, they are a disgrace, also. I told you want to do. You need to change your overall design, because you cannot prompt the user in the middle of a postback. If you're not asking them a question, if you just show a message, you can probably show it in the middle of what you're doing. If you're redirecting to a new page, that page needs to show the message.

Still same error please.

Girish481

I am disgrace, i am robbing my client. Thanks for putting "personal attack" replies in the general forum by such an expert person. Its really shocking how easy they write; who gave them such rights, rather than helping the students/novice developers. I have'nt read anywhere till now, that ignorance is a crime or helping the people means you have full right to "show" the bossism.

Is it not for only AJAX ? is it available for .net 2.0

himanshu2561

Are you using framework 2.0?

himanshu

Girish481

Yes please. I have seen in control panel-add remove programme and there is Microsoft.NET Framework 2.0

himanshu2561

Well you are using .net framework 2.0 So,you have to add reference of "AJAXCONTROLTOOLKIT"
