October 20, 2013 0 Comments

The Basic algorithm behind the scene is,when i click to "Export to word file" button then GridView Data pass into word.So what steps can i take for pass data to word file.
Step-1: First bind GridView control from DataSource.
Step-2: Take a one button control for passing data from GridView control to word file.
Step-3:  For passing GridView data to word file then we must should take response object, Because if we want to get client computer cookies then we can take response object so here we use response object.
Step-4: Clear all content from response buffer using response object.


Step-5: Specify the word file name using Add herader method of response object with content-disposition

Response.AddHeader("content-disposition", "attachment;filename=tarun.doc");

Step-6: The next thing to do set the content type using response object.

Response.ContentType = "application/word";

Step-7:  Use two class first one is StringWriter class and second one is HtmlTextWriter class. Here StringWriter class available in System.IO namespace and inherited from TextWritter class.
Step-8:  Pass object of the StringWriter class to HtmlTextWriter class

   StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);

Step-9 : Invoke RenderControl method of the GridView class.


Step-10: Pass HtmlTextWriter class object to RenderControl method. Here HtmlTextWriter class object contain Text as well as Html content( table control).
Step-11 : Invoke Write method of Response object for writing text to the word file.
Step-12 : Invoke End method of the Response object.

Step-13 : Handle "'GridView' must be placed inside a form tag with runat=server" using Override mwethod.
