In Grid View.. U place a Link Button in the Templete Field and the code as below
protected void lnkDownload_Click(object sender, EventArgs e)
{
try
{
lblError.Visible = false;
LinkButton lnk = (LinkButton)sender;
string strFileName =lnk.CommandArgument.ToString();
if (strFileName == "")
{
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "clientScript", "alert('File Not Found')", true);
}
else
{
//Response.ContentType = "application/octet-stream"
Response.Clear();
Response.ClearContent();
Response.ContentType = "application/x-download";
Response.AddHeader("Content-Disposition", "attachment;filename=" + Path.GetFileName(strFileName));
Response.WriteFile(Server.MapPath(strFileName));
Response.End();
}
}
catch (Exception ex)
{
lblError.Visible = true;
lblError.Text = ex.Message;
}
}
and in the GridView Row Created event u write this code
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton lnk = (LinkButton)e.Row.FindControl("lnkDownload");
lnk.CommandArgument = Convert.ToString(GridView1.DataKeys[e.Row.RowIndex].Values["Doc_Path"]);
}
