Introduction
This article is about creating a custom good-looking submit button. There are a lot of situations, where you will find necessary of using such a control. If you create one site with a particular theme, it is naturally to want all parts (controls) to use the same style. Sometimes regular 'Submit' button doesn't fit, never mind you apply any style on it. These situations happen very often to me, so I created a server control, which I use instead of the regular one.
I will not explain the basics of creating a �User Web Control�, but only specific parts. Here are steps you need to take for creating such a control:
- Create a web application (I am using C# as implementation language)
- Add Custom Web Control
- Write necessary code
- Put control into container (web form)
Explanations
- Create a web application � It is not necessary to create a web application. I have created it, only for debugging purpose. You can create a control without application.
- Add Custom Web Control - if you skip creating a web application, then you need not do ADD, but create a Web Control project.
- Write necessary code � because code is so trivial I will not emphasize on it.

#region Web Form Designer generated code

InitializeComponent();
base.OnInit(e);
}

}
- Put control into a container. Here is the code to be placed into the container:
<%@ Register TagPrefix="uc1" TagName="CuteSubmitButton"
Src="CuteSubmitButton.ascx" %>
<uc1:CuteSubmitButton id="CuteSubmitButton1" Title="enabled button"
Action="CSBTestWebForm.aspx" ImagesPath="images"
Status="enabled"
LinkStyleClass="cutesubmitbutton"
EnabledHelpTitle="This button is enabled."
FormName="CSBForm" runat="server">
</uc1:CuteSubmitButton>
or
<uc1:CuteSubmitButton id=CuteSubmitButton2 title="disabled button"
runat="server" FormName="CSBForm" Status="disabled"
ImagesPath="images" Action="CSBTestWebForm.aspx"
EnabledHelpTitle="This button is disabled."
LinkStyleClass="cutesubmitbutton">
</uc1:CuteSubmitButton>
You should define the css class cutesubmitbutton. Example:
<STYLE>
.cutesubmitbutton
{ FONT: 12px Verdana,Arial,Helvetica,Sans Serif;
COLOR: #003366; TEXT-DECORATION: none }
</STYLE>
Hope you like my solution.
