Solution 1

Try like this

C#

protected void lnkDownload_Click(object sender, EventArgs e)
{
LinkButton lnkbtn = sender as LinkButton;
GridViewRow gvrow = lnkbtn.NamingContainer as GridViewRow;
string filePath = gvDetails.DataKeys[gvrow.RowIndex].Value.ToString();
Response.ContentType = "image/jpg";
Response.AddHeader("Content-Disposition", "attachment;filename=\"" + filePath + "\"");
Response.TransmitFile(Server.MapPath(filePath));
Response.End();
}

Refer:

File download from GridView rows in ASP.NET 4.0[^]
This may help.

Solution 2

This is normal. You can catch that specific exception and then ignore it.
