GridPanel - CommandColumn - download file like Button
Hi,
I have some problems in downloading a file using a CommandColumn included in a GridPanel.
When I try to download a file using the CommandColumn the error message "BADRESPONSE: missing ) in parenthetical" appears.
When I try to download a file using the Button it works perfectly.
I know I missing something but I don't know what.
I need to start the download of the file from the server side, clicking the disk icon at the specific row inside the GridPanel.
Thanks
Sample code:
Code:
<%@ Page Language="C#" %>
<!DOCTYPE html>
<script runat="server">
public class MyRecord
{
public int ID { get; set; }
public String Field { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
List<MyRecord> l_MyRecordList = new List<MyRecord>();
l_MyRecordList.Add(new MyRecord { ID = 0, Field = "Value 0" });
l_MyRecordList.Add(new MyRecord { ID = 1, Field = "Value 1" });
l_MyRecordList.Add(new MyRecord { ID = 2, Field = "Value 2" });
l_MyRecordList.Add(new MyRecord { ID = 3, Field = "Value 3" });
l_MyRecordList.Add(new MyRecord { ID = 4, Field = "Value 4" });
l_MyRecordList.Add(new MyRecord { ID = 5, Field = "Value 5" });
l_MyRecordList.Add(new MyRecord { ID = 6, Field = "Value 6" });
l_MyRecordList.Add(new MyRecord { ID = 7, Field = "Value 7" });
l_MyRecordList.Add(new MyRecord { ID = 8, Field = "Value 8" });
l_MyRecordList.Add(new MyRecord { ID = 9, Field = "Value 9" });
m_Store.DataSource = l_MyRecordList;
m_Store.DataBind();
}
}
protected void m_Button_Click(object sender, DirectEventArgs e)
{
// This works, but I wrote this only for comparison of the two methods
Download(null);
}
[DirectMethod(Namespace = "MyClass")]
public void m_CommandColumn_Command(String p_Command, String p_ID)
{
// This doesn't works
if (p_Command == "Download") { Download(p_ID); }
}
private void Download(String p_ID)
{
String l_SomeText = "Hello World!";
byte[] l_BytesToWrite = Encoding.UTF8.GetBytes(l_SomeText);
Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.ContentType = "text/txt";
Response.AddHeader("Content-Disposition", "attachment;filename=\"Attachment.txt\"");
Response.AddHeader("Content-Length", l_BytesToWrite.Count().ToString());
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.BinaryWrite(l_BytesToWrite);
Response.Flush();
Response.Close();
HttpContext.Current.ApplicationInstance.CompleteRequest();
}
