Introduction: In
this article I will explain how we can Export the Gridview Data to Excel in
Asp.net
Description:
In last article I have explained How to Bind Gridview in Asp.net, How to Export Gridview Data to CSV in Asp.net and How to Export Gridview Data to PDF in Asp.net.
Take a new website. Add a webform to website and design .aspx page as shown below:
<body>
<form id="form1" runat="server">
<div>
<table>
<tr><td> </td><td align="right">
<asp:Button ID="Button1" runat="server" Text="Export To Excel"
onclick="Button1_Click" /></td></tr>
<tr><td> </td><td> <asp:GridView ID="grdstudent"
runat="server"
AutoGenerateColumns="false"
DataKeyNames="STUDENT_ID"
DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="STUDENT_NAME" HeaderText="STUDENT NAME" />
<asp:BoundField DataField="STUDENT_ADDRESS" HeaderText="STUDENT ADDRESS" />
<asp:BoundField DataField="STUDENT_CLASS" HeaderText="STUDENT CLASS" />
</Columns>
</asp:GridView></td></tr>
</table>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$
ConnectionStrings:TestBlogConnectionString %>"
SelectCommand="SELECT * FROM [STUDENT_DETAIL]"></asp:SqlDataSource>
</div>
</form>
Now go to .aspx.cs
page and write the below given code:
public override void
VerifyRenderingInServerForm(Control control)
{
// Verifies
that the control is rendered
}
protected void Button1_Click(object
sender, EventArgs e)
{
try
{
Response.ClearContent();
Response.AddHeader("content-disposition", string.Format("attachment;
filename={0}", "StudentDetail.xls"));
Response.ContentType = "application/ms-excel";
System.IO.StringWriter
sw = new System.IO.StringWriter();
HtmlTextWriter
htw = new HtmlTextWriter(sw);
grdstudent.AllowPaging = false;
grdstudent.DataBind();
grdstudent.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}
catch (Exception ex)
{
}
}
In VB (.aspx.vb)
Public Overrides Sub
VerifyRenderingInServerForm(ByVal control As Control)
' Verifies
that the control is rendered
End Sub
Protected Sub Button1_Click(ByVal
sender As Object,
ByVal e As
System.EventArgs) Handles
Button1.Click
Try
Response.ClearContent()
Response.AddHeader("content-disposition", String.Format("attachment;
filename={0}", "StudentDetail.xls"))
Response.ContentType = "application/ms-excel"
Dim
sw As New
System.IO.StringWriter()
Dim
htw As New HtmlTextWriter(sw)
grdstudent.AllowPaging = False
grdstudent.DataBind()
grdstudent.RenderControl(htw)
Response.Write(sw.ToString())
Response.[End]()
Catch
ex As Exception
End Try
End Sub

If you get any error "Control 'grdstudent' of type 'GridView' must be placed inside a form tag with runat=server" read this article:
