Hello

We have strange behavior on Twinhead Durabook T7M hardware (http://goldrushtechnology.com.au/Products/tabid/57/ProdID/2825/Default.aspx) OS: Microsoft Windows 7 32 bit.

When we try to activate the edit controls (f.e. RadComboBox) via the touch pen, they do not become active. Controls are provided by InlineUIContainer  on the object RadDocument. 

The result is that data can not be replaced via the touch pen. Edit controls have focus only for a fraction of a second, and then focus is lost.

When working with mouse there was no such problem. Installing other drivers for the touch pen did not help.

Problem occurs only for objects placed on the object RadDocument.

Version of Telerik software is 2013 Q2.

Best regards

Daniel Gontarek

Hello Daniel,

Thank you for contacting us.

My attempts to reproduce the issue were not successful. That is why I kindly ask you to provide us more information about the issue that you described and the code that you have used to implement the InlineUIContainer in RadDocument. Also, are you experiencing the issue on other touch devices?

Looking forward to hearing from you.

Regards,

Hello,

For example:
- simple WPF application, on main window only RadRichTextBox (named
radRichTextBox) control;
- in OnLoad event such code:

ComboBox combo = new ComboBox();
combo.Width = 200;
combo.Items.Add("First");
combo.Items.Add("Second");
Telerik.Windows.Documents.Model.InlineUIContainer container = new Telerik.Windows.Documents.Model.InlineUIContainer(combo, new Size(80, 20));
radRichTextBox.Document.InsertInline(container);

Regards,

Hi Daniel,

I'm afraid we are still unable to replicate the issue you are observing. Could you please let us know whether this is the only device where you are experiencing the behavior? 

Additionally, in your first post you mentioned RadComboBox, whereas the code snippet from your last reply shows a ComboBox. Could you please confirm whether the issue occurs in both cases?

If the issue is observed with RadComboBox only, please try the following code and let us know what the results are:
RadComboBox combo = new RadComboBox();
TouchManager.SetIsTouchHitTestVisible(combo, false);

Additionally, we would recommend making sure that the InlineUIContainer where a control is placed is as big as the control in it. Please try setting the proper dimensions to the container and check the behavior again.

On a side note, RadDocument's InsertInline() method has been deprecated and I'd advise you against  using it. Instead, you can use the InsertInline() method of RadRichTextBox like this:
radRichTextBox.InsertInline(container);

I hope these suggestions are useful.

Regards,
Petya
