Is it possible to save and restore sub-grids layout ?

AutoSize? Full HTML support?

DesktopAlert looks nice. Is there a way to automatically size the control to display the entire text? At the moment we have to manually set the FixedSize to get the text displayed fully.

Not every HTML tag is displayable. Not even everything i set in the markup editor is displayed (Hyperlinks or empty lines). Any plans to extend it to full HTML support?

Thank you for this control and please extend it.

HtmlFormatProvider font size

Hello, I am using a combination of RtfFormatProvider and HtmlFormatProvider to allow users to convert Rich Text to HTML. I noticed that even when font size is expressed in RTF in points (or really half-points), when exported to HTML it exports it as pixel sizes - it appears to assume 96 pixels per inch.

Based on this, it changes a 14.5 point font in RTF to a 19.33333 pixel font in HTML.

This works well when the resulting HTML is viewed in an environment that renders at 96 pixels per inch, but in some environments (such as when viewing on a retina display iPad) it makes the font appear much smaller.

Is there a way to control the HtmlFormatProvider to save fonts in points instead of pixels?

handle exception raised by bound IEditableObject.EndEdit

Hello, can I catch the exception raised by a databounditem (that implements ieditableobject and idataerrorinfo) ?

At the moment after the user edit a row and insert invalid values IEditableObject.EndEdit throw an exception and the program terminate.

I also tried to add a Validating event handler but looks like the IEditableObject.EndEdit is called before the Validating event.

Also tried to handle the DataError event but with no success.

Best regards.

Filtering for self-reference hierarchy in gridview

Hello,

I have displayed in datagridview with data in self-reference hierarchy. For example, I have data in the gridview ad the below:

Node1

    Node 1.1

    Node 1.2

        Node 1.2.1

        Node 1.2.2

            Node 1.2.2.1

.....

When I click filtering icon in the header column. The filtering dialog
doesn't display the same structure in the datagridview. It just displays
as the below in filtering dialog.

All

    Node1

    Node 1.1

    Node 1.2

I expect the filtering dialog should display as same as the
datagridview. Please show me how to do. I also attach the screenshot for
more detail

Dropdown list not located directly below control when aspect ratio is changed

I am having a problem with the location of the dropdown list associated with the RadDropDownList control. All of the development has been done on a monitor with a 4 x 3 aspect ratio and the list is always in the correct position. When the application is moved to a monitor with a 9 x 16 aspect ratio, the dropdown list appears far below the control if the control is located near the top of the screen.

RadMessageBox theme bug

There is a small bug with the RadMessageBox. If the application theme is changed (after a RadMessageBox is shown), the button on the message box will retain the original theme. This can be demonstrated in the "Telerik Theme Viewer" demo application shipped with Q2 2014.
