Performance issue with office 2010 MDI form

[Davy]

Hello,

I have an MDI form.

I open different forms as child from the MDI.

All forms are office2010form.

when i use following code the system is ridiculously slow:

          DataTable dt = new DataTable();

                DataColumn dcId = new DataColumn("Id");

                DataColumn dcNaam = new DataColumn("Naam");

                dt.Columns.Add(dcId);

                dt.Columns.Add(dcNaam);

                DataColumn dcSubId = new DataColumn("SubId");

                DataColumn dcSubNaam = new DataColumn("SubNaam");

                dt.Columns.Add(dcSubId);

                dt.Columns.Add(dcSubNaam);

                Outlook.Application oApp = new Outlook.Application();

                Outlook.NameSpace oNS = oApp.GetNamespace("mapi");

                oNS.Logon(Missing.Value, Missing.Value, false, true);

                Outlook.Folders oFolders = oNS.Folders;

                foreach (Outlook.Folder oFolder in oFolders)

                {

                    Outlook.Folders oSubFolders = oFolder.Folders;

                    foreach (Outlook.Folder oSubFolder in oSubFolders)

                    {

                        dt.Rows.Add(new object[] { oFolder.EntryID, oFolder.Name, oSubFolder.EntryID, oSubFolder.Name });

                    }

                }

                oNS.Logoff();

                oNS = null;

                oApp = null;

When i turn off MDI and load the forms to a panel, the outlook code loads fast again.

If i use a normal VS windows MDI form the code also loads fast...

I also noticed that the rest of my application works much faster with MDI turned off.

So there has to be an issue with office2010form MDI mode.

Hi Davy   

   

Thank you for contacting Syncfusion support.   

   

We have checked the reported behavior in our end by using Office2010Form and Microsoft Form.    

    

We are adding ten Office2010Form as Child form of the MDI form. We were unable to get the noticeable time delay when compared to Microsoft Form in our end. We have also prepared the sample and video for your reference.

Hi,

I prepared a example for you:

In the form Menu you have to set the propertie isMdiContainer  from true to false and change the code like this: 

//SLOW Set FORM Menu propertie isMdiContainer = true

FormsMailTests.LeesOutlook frmForm = new FormsMailTests.LeesOutlook("20", "30");
frmForm.MdiParent = this;
frmForm.Show();

//FAST Set FORM Menu propertie isMdiContainer = false
//FormsMailTests.LeesOutlook frmForm = new FormsMailTests.LeesOutlook("20", "30");

//frmForm.Show();              

I solved my problem by not using MDI but FYI ...
