ASP.NET AJAX Tabbed Dialog

For this Tabbed Dialog, you are going to need a MultiView, 2 View and 2 LinkButton. Of course, you can add more controls. I 'm planning to make a templated control so I would like to receive comments.

End Sub

Protected Sub SearchTab_Command(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs)
Dim ctl As WebControl

ctl = CType(up1.FindControl(String.Format("tab{0}", MultiView1.ActiveViewIndex.ToString())), WebControl)
SwitchCss(ctl)

MultiView1.ActiveViewIndex = e.CommandArgument

ctl = CType(sender, WebControl)

Tunning your Code for Performance

When I get a problem about performance issue, The first thing I think are review: loops, comparison and assignments sentences, depending of the kind of project.

In other words:
- Boxing/Unboxing
- Value Types (String, Int, Struct, Class, etc)
- Loops (For each, While, etc)
- Comparison(==, !=, Equals, etc)
- Database Access Topics (DataSet, DataReader, CommandType)
- Exception Handling (Based in Values, Try...Catch)
- Multithreading

XSLT Templates

If you need to add format for display transformation, you can use XSLT templates.

Numeric Templates

<xsl:template name="currencyValue">
<xsl:param name="Number" />
<xsl:value-of select="format-number($Number,'#,###,##0.00')" />
</xsl:template>

<xsl:template name="integerValue">
<xsl:param name="Number" />
<xsl:value-of select="format-number($Number,'####0')" />
</xsl:template>

For invoke them

...

<xsl:variable name="totalRows" select ="count(reg/amount)" />
<xsl:variable name="totalCustomer" select ="sum(reg/amount)" />
...

<xsl:call-template name="currencyValue">
<xsl:with-param name="Number" select="$totalCustomer" />
</xsl:call-template>
...
<xsl:call-template name="integerValue">
<xsl:with-param name="Number" select="$totalRows" />
</xsl:call-template>
...

Your Gmail Account as SMTP Server, ASP NET 2.0

It's gorgeous, when you don't lose time to configure SMTP Server for a simple test. You could use your Gmail Account, to do it.

I read this article before:
Configuring other mail clients
Sending Email with System.Net.Mail
How to use System.Net.Mail.SmtpClient via SSL and Authentication?

Well for accomplish that, first adjust your web.config...

<system.net>
<mailsettings>
<smtp>
<network host="smtp.gmail.com" port="587" username="youraccount@gmail.com" password="yourpassword" defaultcredentials="false">
</network>
</smtp>
</mailsettings>
</system.net>

You write a few lines...

MailMessage message = new MailMessage();

message.From = new MailAddress("sender@domain.com");
message.To.Add(new MailAddress("destination@domain.com"));
message.Subject = "The subject";
message.Body = "The content";

SmtpClient client = new SmtpClient();
client.EnableSsl = true;
client.Send(message);

And run it.
