            string path = MapPath("~/Docfiles/" + filename);
            byte[] bts = System.IO.File.ReadAllBytes(path);
            Response.Clear();
            Response.ClearHeaders();
            Response.AddHeader("Content-Type", "Application/octet-stream");
            Response.AddHeader("Content-Length", bts.Length.ToString());
            Response.AddHeader("Content-Disposition", "attachment; filename=" + 
            filename);
            Response.BinaryWrite(bts);
            Response.Flush();
            Response.End();
        }


    }

I try this in item bound but it not work

C#

protected void Repeater4_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            //DataRowView theDataRowView = e.Item.DataItem as DataRowView;
            //theDataRowView.Row["Status"] == "Status";

            // Only look in data rows, ignore header and footer rows
            if (e.Item.ItemType == ListItemType.AlternatingItem ||
           e.Item.ItemType == ListItemType.Item)
            {
                // Get a data view row object so we can reference the data
                // in the repeater by the bound field names
                DataRowView theDataRowView = e.Item.DataItem as DataRowView;
                //theDataRowView.Row["Status"] == "Status";

                // Make sure we got the data row view before we try to use it
                if (theDataRowView != null)
                {
                    // Get the value of status from the control that holds the value
                    string theStatus = theDataRowView.Row["Status"].ToString();

                    // Find the download link control
                    LinkButton theLinkButtonDownload = e.Item.FindControl("LinkButton1") as LinkButton;

                    if (theStatus.ToLower() == "APPROVE")
                    {
                        if (theLinkButtonDownload != null)
                        {
                            theLinkButtonDownload.Visible = true;
                        }
                    }
                    else
                    {
                        if (theLinkButtonDownload != null)
                        {
                            theLinkButtonDownload.Visible = false;
                        }
                    }
                }

tried debugging the code? Is it entering into the if else block which makes visible true/false?

Try using as below

protected void Repeater4_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {         

            if (e.Item.ItemType == ListItemType.AlternatingItem ||
           e.Item.ItemType == ListItemType.Item)
            {
                Label lblStatus = ( Label ) e.Item.FindControl ( "lblStatus" );//Change label to other controls like literal as per you are using                     

                    // Find the download link control
                    LinkButton theLinkButtonDownload = e.Item.FindControl("LinkButton1") as LinkButton;
 
   if ( lblStatus .Text.Trim ( ) == "APPROVE" )//Use String.Compare with ordinal case to check case sensitiveness instead of == operator  
                    {
                        if (theLinkButtonDownload != null)
                        {
                            theLinkButtonDownload.Visible = true;
                        }
                    }
                    else
                    {
                        if (theLinkButtonDownload != null)
                        {
                            theLinkButtonDownload.Visible = false;
                        }
                    }
                }
            }

R u trying to set the visible false in client side too? in that case dont use string.upper() . use string.compare like <%# String.Compare(Convert.ToString(Eval("Status")),"Reject",true)!=0 %>

If you are trying to do it in design markup then no need to do the same in codebehind
