Where is the example project what shows your problem?

I've attached an example project to the OP.

This code B4XTable1.SearchField.RequestFocusAndShowKeyboard works wonderfully, the B4XTable needs a short moment until it is finished building and only then can you set the focus on the search field.

Set a Sleep(250) to solve your problem.

B4X:

    B4XTable1.SetData(StateData)
    Sleep(250)
    RequestSearchFieldFocus

Thank you for the very simple solution! I thought the CallSubDelayed() was doing that, but apparently not!

I wonder if B4XTable could probably have a _Ready() function. In fact, anything that might take its own sweet time to get ready should probably have one.

That way, we don't have to resort to a kludge of Sleep(), which might be inconsistent between systems in timing. But I guess a few milliseconds will never hurt anyone.

What is best-practice in this case? Would Wait for() be useful here, maybe on the SetData() call?

(Just trying to wrap my head around the B4X paradigm so I don't get stuck like this in the future.)
