writing a custom tag

lamy · October 9, 2006

i have sets of tags that i wanted to write in my html (specifying where it should be) but i couldnt find the right approach for this

atm i made a web control which serves as a place holder, then on my page i find (if its on a master page) the control and assign the content (in a property) while the control (placeholder) overides Render so it gets written to where i placed it

any other way to do this? all i wanted to do is write some custom tags like these

<html>

...

</form>

</html>

it has no order or whatsoever, itll depend on the conditions that i made.

if youre wondering why i needed this its because this page is being read by my winforms application which actually handles the interface (its for a kiosk, the ui for keypads and all those are done in windows control which i invoke if i see those tags)

response.write wont do since i cant tell it where to write it, thats why i made that placeholder so i know where i put it, anyone?

heres what i have atm

my tag writer control

<ToolboxData("<{0}:TagWriter runat=""server""></{0}:TagWriter>")> _
Partial Class TagWriter
   Inherits System.Web.UI.UserControl

   Private _Content As String = String.Empty

   <Personalizable()> _
   Public Property Content() As String
       Get
           Return _Content
       End Get
       Set(ByVal value As String)
           _Content = value
       End Set
   End Property

   Protected Overrides Sub Render(ByVal writer As HtmlTextWriter)
       writer.Write(_Content)
   End Sub
End Class

at code-behind i generate those tags using a class (function returning a string) and assign it to content

from my page (load)

TagWriter1.Content = "something here"

if its on a master page

Dim tag As TagWriter = CType(Page.Master.FindControl("tagWriter"), TagWriter)
tag.Content = "something here"

Try subclassing System.Web.UI.WebControls.WebControl instead.
