Focusing first element in RadDataForm

[Sergey]

Hello!
I use RadDataForm and RadGridView together such as in this demo.
It works fine, but I need to focus first element of Data Form after row selection.
I've studied your API reference, but can't find any way to solve my problem.
Any suggestions about it?
Thank you!

I'm sorry for noise, but do you have any suggestions?

Hi Sergey,

I have prepared an example project that illustrates a possible approach to such a scenario. I am attaching it for your reference.

Hi Ivan,
It doesn't work at my PC. Also, I would like to embed DataForm in GridView.

Hello again :)
May be you know way to getting row detail object for current selected row?

[Sergey]

Hello again and again :)
I've found way to get moment when RowDetails shows - RadGridView.RowDetailsVisibilityChanged.
Now I would like to get controls insed RadDataForm. I tried to use your code, but it doesn't work:

dataForm.ChildrenOfType<DataFormDataField>().First()
                    .ChildrenOfType<TextBox>().First()
                    .Focus();

It throws exception on first .First() call.
Can you sugges any way to enumerating inside controls of RadDataForm?

Hi Sergey,

At that point RadDataForm's fields may not be loaded into the visual tree yet. In order to use this code successfully, you may try invoking it with Dispatcher. However, I have prepared a sample project for you that illustrates a possible way to achieving this. I am attaching it for your reference.

All the best,
