Hi Team,

I am new to Alfresco. I have successfully done with uploading documents into alfresco using dotcmis and displayed that in grid view. I am unable to download that. Please Please help me to achieve that. I have followed the above procedure.

In alfrescoupload page :
   <asp:GridView ID="grdDisplay" runat="server" AutoGenerateColumns="False" CellPadding="0"
                    CellSpacing="0" CssClass="grid table table-bordered table-hover">
                    <AlternatingRowStyle BackColor="White" />
                    <Columns>
                        <asp:BoundField DataField="ClaimName" HeaderText="Claim Name" />
                        <asp:HyperLinkField DataTextField="Name" HeaderText="Document Name" DataNavigateUrlFields="ClaimName, Name" DataNavigateUrlFormatString="~/DownloadFile.aspx?Id={0}&Name={1}" />
                        <asp:BoundField DataField="LastModifiedBy" HeaderText="LastModifiedBy" />
                    </Columns>
                </asp:GridView>

Code Behind : dt.Rows.Add(treeItem.Item.Name, treeItem.Item.LastModifiedBy,tree.Item.Name);

In Download.aspx :

protected void Page_Load(object sender, EventArgs e)
{
Dictionary parameters = new Dictionary();
parameters[DotCMIS.SessionParameter.BindingType] = BindingType.AtomPub;
parameters[DotCMIS.SessionParameter.AtomPubUrl] = "http://127.0.0.1:8080/alfresco/cmisatom";
parameters[DotCMIS.SessionParameter.User] = "admin";
parameters[DotCMIS.SessionParameter.Password] = "root";
string getUserID = Request.QueryString["Id"];
//int userID = Convert.ToInt32(getUserID);
string getDocName = Request.QueryString["Name"];
SessionFactory factory = SessionFactory.NewInstance();
ISession session = factory.GetRepositories(parameters)[0].CreateSession();
IObjectId id = session.CreateObjectId(getUserID);
IDocument doc = session.GetObject(id) as IDocument;
IContentStream contentStream = doc.GetContentStream();
I tried like that. But I was unable to pass id as parameter. Please help me.

Thanks alot

Thanks,

Bharathi

string objectId = <Document Object ID> goes here
            try
                {

                    Document doc = session.GetObject(objectId) as Document;
                    ContentStream contentStream = (DotCMIS.Data.Impl.ContentStream)doc.GetContentStream();
                    using (var fileStream = File.Create(@".\" + contentStream.FileName))
                    {
                        contentStream.Stream.CopyTo(fileStream);
                    }
                    MessageBox.Show("File " + contentStream.FileName + " downloaded successfully");
                }catch(Exception ex)
                {
                    MessageBox.Show("File " + fileName + " download failed." + ex.Message);
                }
