How to export GridView to Word in asp.ner C#

In tutorial, we need "AddHeader" and "ContentType" to do the work.The AddHeader method adds a new HTML header and value to the response sent to the client. It does not replace an existing header of the same name. After a header has been added, it cannot be removed. The ContentType property specifies the HTTP content type for the response. If no ContentType is specified, the default is text/HTML.

This tutorial will show you how to export GridView to Word using ASP.NET 2.0 and C#.

First,you need to import the namespace from System.Data.SqlClient.

using System.Data.SqlClient;
We chose Server Intellect for its dedicated servers, for our web hosting. They have managed to handle virtually everything for us, from start to finish. And their customer service is stellar.

The System.Data.SqlClient namespace contains The System.Data.SqlClient namespace is the .NET Framework Data Provider for SQL Server.The .NET Framework Data Provider for SQL Server describes a collection of classes used to access a SQL Server database in the managed space. In tutorial, we need "AddHeader" and "ContentType" to do the work.The AddHeader method adds a new HTML header and value to the response sent to the client. It does not replace an existing header of the same name. After a header has been added, it cannot be removed. The ContentType property specifies the HTTP content type for the response. If no ContentType is specified, the default is text/HTML.

We use the Button1_Click event to do the work. We then call "Response.AddHeader" to export a file which is named FileName.doc. We then use "Response.ContentType" to denotes the type of the file being exported.

protected void Button1_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;

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

Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.ContentType = "application/vnd.word";
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.GridView1.RenderControl(oHtmlTextWriter);
Response.Output.Write(oStringWriter.ToString());
Response.Flush();
Response.End();
}

public override void VerifyRenderingInServerForm(Control control)
{

}
We migrated our web sites to Server Intellect over one weekend and the setup was so smooth that we were up and running right away. They assisted us with everything we needed to do for all of our applications. With Server Intellect's help, we were able to avoid any headaches!

The front end GridViewExportWordVB.aspx page looks something like this:

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Export to Word" Width="99px" />
 <asp:GridView ID="GridView1" runat="server"> </asp:GridView>
