In this tutorial we will see how to export each single record as an Excel File in Grid View Control. In this example I will just list the code of downloading each gridview record as and Excel file. You can Get the whole code of Saving Recordinto database and binding to Grid View from my previous exampleor you can modify the code according to your requirement.
Steps to Export Each GridView Record as an Excel File:
Step 1: Add a template field inside the grid view design view as shown below:
<asp:TemplateFieldHeaderText="Download File"ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:ImageButtonID="btnDownload"runat="server"ImageUrl="~/images/icon_excel.png"OnClick="btnDownload_click"ToolTip="Download Excel File"/>
</ItemTemplate>
Step 2: In the code behind file add the following code:
protectedvoidbtnDownload_click(object sender, ImageClickEventArgs e)
{
con.Open();
ImageButton btnDetail = sender asImageButton;
GridViewRow gvrow = (GridViewRow)btnDetail.NamingContainer;
hdid.Value = Convert.ToString(GridView1.DataKeys[gvrow.RowIndex].Value);
string qry2 = "Select STU_NAME, CLASS, EMAIL from Student_Record where STU_ID=" + hdid.Value + "";
SqlDataAdapter adp = newSqlDataAdapter(qry2, con);
DataTable dt = newDataTable();
adp.Fill(dt);
if (dt.Rows.Count > 0)
{
ExportToSpreadsheet(dt, "DataFile");
}
con.Close();
}
publicstaticvoid ExportToSpreadsheet(DataTabletable, string name)
{
HttpContext context = HttpContext.Current;
context.Response.Clear();
foreach (DataColumncolumn in table.Columns)
{
context.Response.Write(column.ColumnName + "\t");
}
context.Response.Write(Environment.NewLine);
foreach (DataRowrow in table.Rows)
{
for (int i = 0; i < table.Columns.Count; i++)
{
context.Response.Write(row[i].ToString().Replace(";", string.Empty) + "\t");
}
context.Response.Write(Environment.NewLine);
}
context.Response.Buffer = true;
context.Response.ContentType = "application/vnd.ms-excel";
context.Response.AppendHeader("Content-Disposition", "attachment; filename=" + name + ".xls");
context.Response.End();
}
You can modify the database record fetching query(qry2) above in code according to your table and the records shown in the grid view.
If you get any problem during implementing the code then let us know through comments.Other Related Posts:
