Example:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GdvMainmasters" Runat="server" DataSourceID="OrdrDb">
<Columns>
<asp:BoundField DataField="OrderID" HeaderText="OrderID" 
SortExpression="OrderID" />
<asp:BoundField DataField="OrderName" HeaderText="OrderName" 
SortExpression="OrderName" />
<asp:BoundField DataField="Phone" HeaderText="Phone" SortExpression="Phone" />
<asp:BoundField DataField="Address" HeaderText="Address" 
SortExpression="Address" />
<asp:BoundField DataField="Amount" HeaderText="Amount" 
SortExpression="Amount" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="OrdrDb" runat="server" 
ConnectionString="<%$ ConnectionStrings:TestConnectionString %>" 
SelectCommand="SELECT * FROM [Orders]"></asp:SqlDataSource>
<asp:Button ID="btnexportOrderstoWord" runat="server" Text="ExportExcel" 
onclick="btnexportOrderstoWord_Click" /></div>
</asp:GridView>
<asp:Lable id="LblMsg" runat="server"/>
<asp:Button id="BtnSendtoExcel" Text="Export" runat="server" OnClick="BtnSendtoExcel_Click"/>
</div>
</form>
</body>
</html>

CodeBehind:

protected void BtnSendtoExcel_Click(object sender, EventArgs e)
{
try
{
Excelbtn = "ABC";
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",attachment;filename=OrderDetails.xls");
Response.ContentType = "application/ms-excel";
StringWriter swr = new StringWriter();
HtmlTextWriter hwr = new HtmlTextWriter(sw);
GdvMainmasters.AllowPaging = false;
GdvMainmasters.AutoGenerateSelectButton = false;
GdvMainmasters.Enabled = false;
GdvMainmasters.DataBind();
GdvMainmasters.HeaderRow.Cells[0].BorderStyle = BorderStyle.Inset;
GdvMainmasters.HeaderRow.Cells[1].BorderStyle = BorderStyle.Inset;
GdvMainmasters.HeaderRow.Cells[2].BorderStyle = BorderStyle.Inset;
GdvMainmasters.HeaderRow.Cells[3].BorderStyle = BorderStyle.Inset;
GdvMainmasters.HeaderRow.Cells[3].BorderStyle = BorderStyle.Inset;
for (int j = 0; j < GdvMainmasters.Rows.Count; j++)
{
GridViewRow row = GdvMainmasters.Rows[j];
GdvMainmasters.RenderControl(hwr);
Response.Write(swr.ToString());
Response.Flush();
Response.End();
}
catch (Exception e3)
{
LblMsg.Text = e3.Message;
}
}

Note:While run the above code we may get the some errors RegisterForEventValidation can only be called during Render.If you get an error then need to override the control.

Export data to excel in c#

Title:How to export grid view data to excel in asp.net using c#.net

Description:
Basically we can export the data to excel in two ways in asp.net with c#. One is using Download Format and Other one is using Microsoft.Office.Interop.Excel .In the Download format ,it will render the grid view and export in XLST format.It is used when the data is export from grid view to excel.In Interop.Eexcel will create excel file dynamically and load the data into it.Exporting data to excel its pretty simple. Let's see how this can be done.For this i have taken data from database first then fill the existing data set.The following name space i have used for excel properties
Asp.Net Export to excel:

using Microsoft.Office.Interop.Excel;

Create Excel document:

Excel.Application App;
Excel.Workbook WorkBook;
Excel.Worksheet WorkSheet;
object misValue = System.Reflection.Missing.Value;
App = new Excel.Application();
WorkBook = App.Workbooks.Add(misValue);
WorkSheet = (Excel.Worksheet)WorkBook.Worksheets.get_Item(1);

Load the data into Excel file:
Here i will get the data into data set then it will load in to excel file using the following iteration.

for (int col = 0; col < dsreportdata.Tables[0].Columns.Count; col++)
{
for (int row = 0; row < dsreportdata.Tables[0].Rows.Count; row++)
{
WorkSheet.Cells[row + 12, col + 3] = dsreportdata.Tables[0].Rows[row].ItemArray[col].ToString();
}
}
