Handling Server Control Events


Learn More about Server Intellect


Each ASP.NET server control is capable of exposing an object model containing properties, methods, and events. ASP.NET developers can use this object model to cleanly modify and interact with the page.

The following example demonstrates how an ASP.NET page developer can handle the OnClick event from the <asp:button runat=server> control to manipulate the Text property of the <asp:label runat=server> control.

<html>
<head>
</head>

<script language="VB" runat=server>

Sub SubmitBtn_Click(Sender As Object, E As EventArgs)
Message.Text = "Hi " & Name.Text & ", you selected: " & Category.SelectedItem.Text
End Sub

</script>

<body>

<center>

<form action="form.aspx" method="post" runat="server">

<asp:adrotator AdvertisementFile="ads.xml" BorderColor="black" BorderWidth=1 runat="server"/>

<h3> Name: <asp:textbox id="Name" runat="server"/>

Category: <asp:dropdownlist id="Category" runat=server>
<asp:listitem >psychology</asp:listitem>
<asp:listitem >business</asp:listitem>
<asp:listitem >popular_comp</asp:listitem>
</asp:dropdownlist>
</h3>

<asp:button text="Lookup" OnClick="SubmitBtn_Click" runat="server"/>

<p>

<asp:label id="Message" runat="server"/>

</form>

</center>

</body>
</html>

This simple sample is functionally equivalent to the sample demonstrated earlier in this section. Note, however, how much cleaner and easier the code is in this new server-control-based version.
