Hi,

I am getting an instance of ADXOlForm in ThisAddIn.cs of Outlook AddIn as below

public TestADXOlForm tpControl;
Dispatcher.Invoke(() =>
{
this.FormsManager = AddinExpress.OL.ADXOlFormsManager.CurrentInstance;
this.FormsManager.OnInitialize +=
new AddinExpress.OL.ADXOlFormsManager.OnComponentInitialize_EventHandler(this.FormsManager_OnInitialize);
this.FormsManager.Initialize(this);
});
#endregion
Dispatcher?.Invoke(() =>
{
tpControl = TestADXOlFormItem.FormInstances(0) as TestADXOlForm;
tpControl.Width = 65;
});

But the width of tpControl shown as 292 at a later point while debugging.
One more issue is when I try to change tpControl width to 65 later, the width of tpControl shown as 74.

Below is how the form is being initialized
TestADXOlFormItem= new ADXOlFormsCollectionItem();
TestADXOlFormItem.ExplorerLayout = ADXOlExplorerLayout.DockRight;
TestADXOlFormItem.ExplorerItemTypes = ADXOlExplorerItemTypes.olMailItem;
TestADXOlFormItem.AlwaysShowHeader = false;
TestADXOlFormItem.ExplorerAllowedDropRegions = ADXOlExplorerAllowedDropRegions.DockRight;
TestADXOlFormItem.IsMinimizedStateAllowed = false;
TestADXOlFormItem.IsDragDropAllowed = false;
TestADXOlFormItem.CloseButton = false;
TestADXOlFormItem.UseOfficeThemeForBackground = true;
TestADXOlFormItem.FormClassName = typeof(TestADXOlForm).FullName;
TestADXOlFormItem.Cached = ADXOlCachingStrategy.OneInstanceForAllFolders;
TestADXOlFormItem.Splitter = ADXOlSplitterBehavior.None;
TestADXOlFormItem.IsHiddenStateAllowed = false;
this.FormsManager.Items.Add(TestADXOlFormItem);

Everything was working fine when TestADXOlFormItem.ExplorerLayout = ADXOlExplorerLayout.RightReadingPane
I would like to know why is the width changing automatically than what we set.

Thanks
Siva

Hello Siva,

The size depends on may things at this point. Could you please provide us with a sample project reproducing that issue?

You can send it to the support email address; find it in {Add-in Express installation folder}\readme.txt; please make sure your email contains a link to this topic.

Hello Siva,

I've just received a word from our guys. What you see is a result of two issues. First off, the minimal pane width is 84 in your case; you use a Dock* region which is implemented using Microsoft's Custom Task Pane.

You should know that this value is set by Office, it depends on the current DPI in an undocumented fashion, and there's no way to get this value beforehand. When you try to set the width to a value less than this, your form width will be reset to that width.

The other issue is an Add-in Express related. When performing calculations and drawing *when your form is being reset to the minimal width*, there's some issue that spoils the picture. We will look into this but you shouldn't expect anything grand: you can't set the form width less than the minimal value and you can't find that value ahead of time.

Hi Andrei,

Do you mean that the minimum width for a custom task pane in Outlook is 84?
Regarding Add-in Express related - what is the issue when the form width is being set to default.

Regards
Siva

I wrote:

This value depends on the DPI used: you can change DPI to check this. It is defined by the underlying Custom Task Pane.

When you set the width, say, to 65, Add-in Express sets that width to the form and then it detects that the pane width is not 65 but it is set to 84. Here, Add-in Express processes this new width and, we suppose, it does this in a wrong DPI context and this causes the incorrect values that you get; a research is required to get the full understanding of the issue. We've filed it down under #18106 in our issue-tracking DB. When the issue is fixed, you'll see this number in whatsnew.txt.
