Production of rolling news with icons (ASP. net c #)

There may be a lot of beginner friends like me (especially those who have studied ASP) who have such a confusion. How does Asp.net (C #) Implement rolling news?

Let's take a simple example and leave a file for yourself.

< Marquee Onmouseover = "Javascript: this. Stop ();" Onmouseout = "Javascript: This. Start ();" Scrollamount = "1"

Direction = "Up" Style = "Width: 401px; Height: 132px" >

< ASP: DataGrid ID = Dgnews Runat = "Server" Height = "132px" Width = "392px" Borderstyle = "NONE" Showheader = "False" Gridlines = "NONE" Bordercolor = "White" Autogeneratecolumns = False Datasource = "<% # Dvnews %>" >

< Columns >

< ASP: boundcolumn Datafield = "Postid" Dataformatstring = "& Lt; IMG src = images/arrow.gif & gt ;" >

< Itemstyle Width = "10px" >

</ Itemstyle >

</ ASP: boundcolumn >

< ASP: hyperlinkcolumn Target = "_ Blank" Datanavigateurlfield = "Postid" Datanavigateurlformatstring = "Shownews. aspx? Postid = {0 }" Datatextfield = "Title" Sortexpression = "Postdate" > </ ASP: hyperlinkcolumn >

</ Columns >

</ ASP: DataGrid >

</ Marquee >

Dvnews is the data we obtain from the database.
