Question

I have a gridview control in ASP.Net 2.0 and i need to export this gridview data into CSV file.

I have bind this gridview with the dataset.After binding the dataset to the gridview i have done some changes in the gridview data like if I got 0 in dataset then i show 0 as “Started” in the gridview and if i got 1 in the dataset then I show 1 as “Not Started” in the gridview.

So, i can’t use dataset directly for exporting. What i need is..i want the code (in c#) that export my gridview data(not dataset’s data) into CSV file.

Answer 1

Try following code, i used it already many times. It will export the data directly from gridview to csv file specified in the code.

protected void btnExportCSV_Click(object sender, EventArgs e)
{
    Response.Clear();
    Response.Buffer = true;
    Response.AddHeader("content-disposition",
     "attachment;filename=GridViewExport.csv");
    Response.Charset = "";
    Response.ContentType = "application/text";

    GridView1.AllowPaging = false;
    GridView1.DataBind();

    StringBuilder sb = new StringBuilder();
    for (int k = 0; k < GridView1.Columns.Count; k++)
    {
        //add separator
        sb.Append(GridView1.Columns[k].HeaderText + ',');
    }
    //append new line
    sb.Append("\r\n");
    for (int i = 0; i < GridView1.Rows.Count; i++)
    {
        for (int k = 0; k < GridView1.Columns.Count; k++)
        {
            //add separator
            sb.Append(GridView1.Rows[i].Cells[k].Text + ',');
        }
        //append new line
        sb.Append("\r\n");
    }
    Response.Output.Write(sb.ToString());
    Response.Flush();
    Response.End();
}
