How to Add Asp.Net Controls in XSLT ?

It is very good to know how we can add asp.net controls in XSLT.

We know by using XSLT we can transform XML document to any format like HTML, DHTML... so on.

I think most of the users are working with html controls inside the XSLT , but How to use Asp.Net Controls ?

Step 1:  Add xmlns for Asp.net

I think you kow XSLT is having stylesheet element , here we need to specify the namespace for the XSL trnsformation.
For our requirement we need to use xmlns:asp="remove"

Step 2:  Parse the asp.net Controls

You need to parse the controls in Pgae_InIt Event

Why we need to Do parsing ?

The transformed XML need to  be converted  to asp.net controls if the transformed xml is having any asp.net controls .

Note:
 Once you have transformed xml you need to replace "xmlns:asp="remove" with empty string .
