Standard question #1:
What do you mean by "not working"?
Remove the "javascript:" protocol from the code. You only use a protocol when you are putting Javascript in the url, i.e. in the href property of a link.
---
b { font-weight: normal; }
|
|
|
|
|
Button1.Attributes.Add("onclick", "javascript:history.go(-1);return false;")
or
Button1.Attributes.Add("onclick", "history.go(-1);return false;")
Should work for you.

|
|
Thanx, it works. Why without "return false;" it doesn't work?

HTML (Hyper Text Markup Language) defines the layout of a web page. The web page can display text, graphics, hyper links, render audio and other data in the form of tags and attributes.
Web Servers all around the globe host HTML pages to be accessed by Clients running Browsers like IE or Firefox through HTTP protocol HyperText Transfer Protocol.
The protocol that makes web servers and browser connect to each other is HTTP protocol (Hyper Text Transfer Protocol)
SOAP (Simple Object Access Protocol) is a protocol that facilitates one program running in one system to interact with another program running in another system. The beauty of SOAP is that each system can have its own operating system/hardware. It need not be from the same vendor.
As long as the disparate systems can understand HTTP/XML protocol, the systems can communicate with one and another. XML is very much like HTML; however XML defines the structure of the data & embeds data in it.
The main purpose of communication between two systems is to share processed data & the shared data is primarily represented in the form an XML.
Web Server sends HTML -> Renders as web page in Browsers
Web Server sends HTML (HTML contains embedded XML representing data) -> Browsers Clients or Other client programs that understands HTTP protocol opens the HTML,reads the embedded XML. The XML contain the data and its structure.

hi everyBody,
i hav made an control which is submiting a form and data into database,
dis control is used in an myform.aspx page and dat page is working fine in mozila
but not working in internet explorer. i think some thing is blocking javascript, when form is run in internet explorer, the click event of submit button does't work but work fine in mozila.
following code i m using:
control code :
--------------------------
<%@ Control Language="vb" AutoEventWireup="false" Codebehind="testControl.ascx.vb" Inherits="my.testControl" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<asp:textbox id="TextBox1" runat="server">
<asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server" errormessage="RequiredFieldValidator"
="" controltovalidate="TextBox1">
<asp:regularexpressionvalidator id="RegularExpressionValidator1" runat="server" errormessage="RegularExpressionValidator"
="" controltovalidate="TextBox1" validationexpression="^([a-zA-Z0-9_ ,]{1,120})$">
<asp:textbox id="TextBox2" runat="server">
<asp:requiredfieldvalidator id="RequiredFieldValidator2" runat="server" errormessage="RequiredFieldValidator"
="" controltovalidate="TextBox2">
<asp:regularexpressionvalidator id="RegularExpressionValidator2" runat="server" errormessage="RegularExpressionValidator"
="" controltovalidate="TextBox2" validationexpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*">
<asp:button id="submit" runat="server" text="Button">
-------------------------------------------------------------------------------
this is my aspx page where control is called:
<%@ Page %>
<%@ Register TagPrefix="My" TagName="Test" Src="~\allControls\testControl.ascx" %>
<title>Application
<body
<form runat="server">
<my:test id="myTest" runat="server">
------------------------------------------------------------------------
this is the click event of the sumit(button)
Private Sub submit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submit.Click
If Page.IsValid Then
Dim strConn As String = Application("dbStrConn")
Dim MyConn_member As New SqlConnection(strConn)
MyConn_member.Open()
'transaction
Dim MyTrans As SqlTransaction = MyConn_member.BeginTransaction
Try
'Specify the first statement to run...
Dim MySql_member As String = "insert into test ([name],[email])values(@name,@email)"
'Create the SqlCommand object, specifying the transaction through
Dim cmd_member As New SqlCommand(MySql_member, MyConn_member, MyTrans)
cmd_member.Parameters.Add(New SqlParameter("@name", TextBox1.Text))
cmd_member.Parameters.Add(New SqlParameter("@email", TextBox2.Text))
cmd_member.ExecuteNonQuery()
MyTrans.Commit()
Catch ex As Exception
'Something went wrong, so rollback the transaction
MyTrans.Rollback()
MyConn_member.Close()
Throw 'Bubble up the exception
Finally
'Finally, close the connection
MyConn_member.Close()
End Try
End If
End Sub
this click event is working in mozila but not working in Internet Explorer.
thanx

You have to be more specific in your question.
Do you mean how many classes there are in the .NET framework? Do you mean how many objects there is available in the Page class? Do you mean how many object instances you can create?

If you want to retrive the uploaded file.... use anchor tag and place the file path in the href attribute of the achor tag.
<a href="uploads/myfile.doc">My File</a>

Pavan.

That depends on the type of the file, for example if u uploaded an image and u wantto display it u add an image tag to your webform and fill the ImageUrl property with the path of the image u saved on ur web server and so on
