Hello friends,
Can anybody tell me how to check manually whether the Email-id entered in textbox is valid or not, without using Regular Expression validator control.
Thanks,
Nagendra

You can use regular expressions in javascript, which is what the validator does, you can do some nasty string mashing because you refused to use the right tool for the job, that's about it really.

Sure, if you like. It will help if you spell 'left' correctly.
What do you expect this to do ?

I don't know, but I am guessing if you'd tried it, you'd have found your answer by now.
A quick google leaves me thinking this is generally good CSS, but not in javascript for window.open

It would be in the query you given in SQLDataSource.

Walking through the StackTrace, doesn't it indicate the affected classes from your application?

I doubt, since OP uses nasty SQLDataSource for binding.

True. And for a beginner, it would be a significantly scary.

What does it means by OP? does this error looks complex? i hope it is not since i'm a beginner. i will post the codes and hope all of you will help.

The error is obvious. How many places do you use the keyword 'order' in your code ? Perhaps if you post your SQL we can help ?

I'm using Web User Control for Order.aspx file. This is SQL code for Order.ascx.
<pre>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
SelectCommand="SELECT Order.OrderNum, Order.OrderDate, Order.CustEmail, Order.Subtotal, Order.Shipping, Order.Total,
Customers.LastName, Customers.FirstName, Customers.Address, Customers.City, Customers.State, Customers.PostCode, Customers.Phone, Customers.Country
FROM Order
INNER JOIN Customers
ON Order.CustEmail=Customers.Email
WHERE Order.OrderNum=@OrderNum
ORDER BY Order.OrderNum">
<SelectParameters>
<asp:SessionParameter Name="OrderNum" SessionField="OrderNum" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
SelectCommand="SELECT [ProductId], [Name], [Price], [Quantity], [Total], [OrderNum]
FROM [OrderItems]
WHERE ([OrderNum]=@OrderNum)
ORDER BY [ProductId]">
<SelectParameters>
<asp:ControlParameter Name="OrderNum" ControlID="FormView1"
PropertyName="SelectedValue" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
</pre>
|
|
|
|
|
And this is code for Order.aspx. Incorrect syntax that I can't find. That makes me really worried!
<pre>
<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" Title="Untitled Page" AutoEventWireup="False" %>
<%@ Register Src="~/Manage/Order.ascx" TagName="Order" TagPrefix="uc1" %>
<script runat="server">
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
If Not IsPostBack Then
ddlOrder.DataBind()
End If
Session("OrderNum") = ddlOrder.SelectedValue
End Sub
</script>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
Choose an order to display:
<asp:DropDownList ID="ddlOrder" runat="server" AutoPostBack="True"
DataSourceID="SqlDataSource1" DataTextField="OrderNum"
DataValueField="OrderNum">
</asp:DropDownList>&nbsp;
<asp:LinkButton ID="LinkButton1" runat="server"
PostBackUrl="~/Manage/PrintOrder.aspx">Print this page</asp:LinkButton>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ProjectConnectionString %>"
SelectCommand="SELECT OrderNum FROM Order ORDER BY OrderNum">
</asp:SqlDataSource><br /><br />
<uc1:Order ID="Order1" runat="server" />
</asp:Content>
</pre>

I guess I would add a space after the word Order.
I guess that you concatenate strings like
String query = String.Empty;
query += "Select * FROM Order";
query += "Where Value = 1";
if you would check the content of the string query it would read:
Select * FROM OrderWhere Value = 1
Maybe this makes your problem clear.

I want to convert this string to excel(*.xls) .
I try this :
<br />
f = New FileInfo("c:\test.xls")<br />
f.Delete()<br />
s = f.CreateText<br />
<br />
s.WriteLine('string from xml.txt')<br />
s.Close()<br />
<br />
<br />
<br />
<br />
This code can generate the excel file but when i import excel's data
by this code:
<br />
Dim ds As New DataSet<br />
Dim Olecn As OleDb.OleDbConnection<br />
Dim da As OleDb.OleDbDataAdapter<br />
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _<br />
"Data Source=" & FilePath & ";" & _<br />
"Extended Properties=""Excel 8.0;HDR=Yes"""<br />
Olecn = New OleDb.OleDbConnection(strConn)<br />
Olecn.Open()<br />
da = New OleDb.OleDbDataAdapter("SELECT * FROM [" + SheetName + "$]" ), strConn)<br />
Try<br />
da.Fill(ds)<br />
Catch<br />
<br />
Finally<br />
Olecn.Close()<br />
End Try<br />
Return ds<br />
This not works.
I can't import data that create from this excel.
I don't know why .
Thanks in advance

from page 1.aspx, when the user clicks a link, page 2.aspx appears (a popup window).
this popup (page 2.aspx) has no addressbar or toolbar.
i am getting users emial address and few more detail from this page(page 2.aspx).
i have this code in page 2.aspx code behind.
<br />
If Not Page.IsPostBack Then<br />
' Save the referrer Url<br />
ViewState("ReferrerUrl") = Request.UrlReferrer.ToString()<br />
End If<br />
what happens is, whenever i try this link from IE i am getting this errro:
Object reference not set to an instance of an object.
Line 18: If Not Page.IsPostBack Then
Line 19: ' Save the referrer Url
Line 20: ViewState("ReferrerUrl") = Request.UrlReferrer.ToString()
Line 21: End If
it shows that line 20 has error.
but this same codes works fine with Firefox.
why IE is giving me the erorr?

Meax wrote: Object reference not set to an instance of an object.
It means your Request.UrlReferrer is null. Since it's a popup, IE don't get the referrer. I am not sure why this works with firefox and not with IE. HTTP referrer is unreliable and many firewalls can strip that out. Alternatively check you are getting referrer using JS. Or use window.opener.location which gives opener window's location (referrer).

Hello,
I know that Focus is a client-side event but is there a way to call a server-side event in my code-behind file in reponse to focus change in a DropDownList? Something like,
1. Handle the focus in the javascript in the .aspx file
2. call a server-side method inside that javascript event handler?
Is that possible at all? If yes a code sample would help, becasue whatever I tried did not seem to work.
THanks for reading!

You can force a postback by examining the javascript that does it in general. Or you can make an AJAX call.
