How To Make Moving Text On Web Form?
Let say you want to create welcome message or some announcement message. In some cases, this message will be more effective if text is moving over the form in some direction, like this message bellow:
To achieve this, you need to use <marquee > HTML tag. To specify direction, you need to use its direction attribute. So, to create first message, you can use this code:
<marquee direction="left">Hello visitor, this is a message that goes to left.</marquee>
Direction attribute have 4 possible values: left, right, up and down.
You can manipulate marquee tag with ASP.NET server side code. To do this, you need to add runat="server" attribute and set id attribute to some meaningful value, like this:
<marquee id="MyMovingText" runat="server" direction="left"></marquee>
Then, on server side, you can edit its message with code like this:
[ C# ]
MyMovingText = "Hello " + strUserName;
[ VB.NET ]
MyMovingText = "Hello " & strUserName
Marquee tag remarks
If you type <marquee > tag in Visual Studio IDE, you'll see that is underlined with green color and warning message: Validation (XHTML 1.0 Transitional): Element 'marquee' is not supported. So, marquee tag will not pass validation, but it will show in last versions of major web browsers. Depending of your needs, you can decide to simply ignore this message as it is not so much important.
You are not limited to plain text inside marquee. Inside tags can be any HTML, like hyperlinks, images, css formated content etc.
