Hi Neda,
One can declare Protected property as
protected string Filename { get; set; }
And set value as
Filename = "flash/Test.swf";
On page is this property can be accessed as
<object width="400" height="300">
<embed src='<%= this.Filename %>' type="application/x-shockwave-flash" width="200" height="200"></embed>
</object>
However I have set the propery with hardcoded value, you can change with database value.
Thanks and Regards,
Rk_Hirpara
