ASP.NET Web Forms - Button control
The ASP.NETButton control is used to set buttons. This section introduces the use of Button control. The Button control is used to display a push button. Button control The Button control is used to display a push button. The push button may be a submit button or a command button. By default, this control is a submit button. The submit button has no command name, and when it is clicked, it posts the page back to the server. You can write some event handlers to control the execution of actions when the submit button is clicked. Command buttons have command names and allow you to create multiple Button controls on the page. You can write some time handles to control the execution of actions when the command button is clicked. The Button control's properties and properties are listed in our WebForms Controls Reference manual page. The following example demonstrates a simple Button control:
<html><body><form runat="server"><asp:Button id="b1" Text="Submit" runat="server" /></form></body></html>
Add script forms are typically submitted with the click of a button. In the following example, we declare a TextBox control, a Button control, and a Label control in the .aspx file. When the submit button is triggered, the submit subroutine will be executed. The submit subroutine will write a line of text to the Label control: Example
<script runat="server">Sub submit(sender As Object, e As EventArgs)lbl1.Text="Your name is " & txt1.TextEnd Sub</script><html><body><form runat="server" >Enter your name:<asp:TextBox id="txt1" runat="server" /><asp:Button OnClick="submit" Text="Submit" runat="server" /><p><asp:Label id="lbl1" runat="server" /></p></form></body></html>
