问题
Is there an alternative to using this since using a <form runat="server">
will cause a 500 error.
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}
EDITED
With the assistance from @HansDerks I ended up using the following(a jazzed up version of the solution provided.):
protected void Export_Click(object sender, System.EventArgs e)
{
StringWriter writer = new StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(writer);
GridView gridView = new GridView();
gridView.DataSource = MySqlDataSource;
gridView.AutoGenerateColumns = true;
gridView.DataBind();
gridView.HeaderRow.Style.Add("background-color", "#003c74");
gridView.HeaderRow.Style.Add("color", "#ffffff");
for (int i = 0; i < gridView.Rows.Count; i++)
{
GridViewRow row = gridView.Rows[i];
//Change Color back to white
row.BackColor = System.Drawing.Color.White;
//Apply text style to each Row
row.Attributes.Add("class", "textmode");
//Apply style to Individual Cells of Alternating Row
if (i % 2 != 0)
{
row.BackColor = System.Drawing.Color.AliceBlue;
}
}
gridView.RenderControl(htmlWriter);
htmlWriter.Close();
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=filename.xls");
Response.Charset = "";
Response.Write(writer.ToString());
Response.End();
}
I hope you guys will find it useful. Thanks everyone!

If you have the datasource you can try this (replace datatable with relevant datasource)
private void DataTableToExcel(DataTable dataTable)
{
StringWriter writer = new StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(writer);
GridView gridView = new GridView();
gridView.DataSource = dataTable;
gridView.AutoGenerateColumns = true;
gridView.DataBind();
gridView.RenderControl(htmlWriter);
htmlWriter.Close();
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = "";
Response.Write(writer.ToString());
Response.End();
}

If you use the DNN grid control, which is based on a Telerik control, you can export the visible contents of the grid with:
protected void OnExportCSVClick(Object sender, EventArgs e)
{
grdMemberTypes.MasterTableView.ExportToCSV();
}
This applies to DNN 7.0 though.
Unfortunately, if you have paging turned on, it only outputs the data from the visible rows.
