Hi, i have been trying to use the javascript confirmation box to delete files from a Gridview, however when ever i click "cancel" on the box it still deletes the file! i really need some help, heres the code i have:

<asp:TemplateField HeaderText="Delete File">
                            <ItemTemplate>
                                <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false" CommandName="Delete" 
                                    OnClick="DeleteRowButton_Click" OnClientClick="confirm_delete()">
         Permanently Delete This File</asp:LinkButton>
                            </ItemTemplate>


<script type="text/javascript">
    function confirm_delete() {
        if (confirm("Are you sure you want to delete the highlighted file? ") == true)
            return true;
        else
            return false;

    }
     </script>


//Delete a selected file from the Server and Gridview
void DeleteRowButton_Click(Object sender, EventArgs e)
        {
            
                //Delete file from the server
                String fileName = GridView1.SelectedRow.Cells[1].Text;

                String filePath = "/UploadedUserFiles/" + User.Identity.Name + "/" + fileName;

                System.IO.File.Delete(Server.MapPath(filePath));

                lblDeleteResult.Text = fileName + " was successfully deleted!";

                // Programmatically delete the selected record from the gridview
                GridView1.DeleteRow(GridView1.SelectedIndex);
                //Refresh Gridview
                GridView1.DataBind();

                UploadDetails.Visible = false;
                          
        }

basically the DeleteRowButton_Click method runs regardless of whether i click cancel. i would like it to run this method if i click "ok" and do nothing when a click "cancel"

any ideas?
thanks

In case "OK" is clicked then return true else when "Cancel" is clicked then return false which will not submit your page and the row will not get deleted.

Please define Javascript onClientClick function as below
OnClientClick="return confirm_delete()"
And that should resolve your issue.
