How to export data grid view to doc file?

To export data grid view to excel file follow these steps:

1. Write a function export( ) as:

 private void export(string filename, string type)

        {

            Response.Clear();

            Response.Buffer = true;

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

            Response.Charset = "";

            Response.ContentType = type;

            StringWriter sw = new StringWriter();

            HtmlTextWriter hw = new HtmlTextWriter(sw);

            GridView1.RenderControl(hw);      //render the gridview 

            Response.Output.Write(sw.ToString());

            Response.Flush();

            Response.Close();

            Response.End();

        }

here name of our grid view is GridView1  so we have used GridView1.RenderControl(hw);

2. Write public override void and select  VerifyRenderingInServerForm(Control control) from intelisense, function will displayed as:

 public override void VerifyRenderingInServerForm(Control control)

        {

            base.VerifyRenderingInServerForm(control);

        }

Now comment the line in function as:

public override void VerifyRenderingInServerForm(Control control)

        {

          //  base.VerifyRenderingInServerForm(control);

        }

We have done this for rendering of data grid view

3. Now call the function export( )  on button_click( ) as:

export("myfile.doc","application/msword");

the file will be saved as myfile.doc you can specify other name for file also.

for exporting to .docx file use "application/vnd.openxmlformats-officedocument.wordprocessingml.document" instead of "application/msword" and change the file extension as "myfile.docx"
