Android Question CustomLayoutDialog in Loop

[mw71]

Hi,

i use the follow Code:

Do While rbtn_check < 2
            rbtn_check=0

            Dim sf As Object = cld.ShowAsync("Export","","Start"),"Cancle",Null,False)
            cld.SetSize(90%x,hoehe + 150dip)
            Wait For (sf) Dialog_Ready (DialogPanel As Panel)

            DialogPanel.AddView(pnl, 0, 0, DialogPanel.Width, DialogPanel.Height)    'pnl is a Panel
            Wait For (sf) Dialog_Result (ret As Int)

            If ret=DialogResponse.NEGATIVE Then Exit

            If rbtn_port_ja.Checked=True Or rbtn_port_nein.Checked=True Then rbtn_check=1
            If rbtn_ref_ja.Checked=True Or rbtn_ref_nein.Checked=True Then rbtn_check=rbtn_check+1
            If rbtn_check<2 Then
                MsgboxAsync(Starter.loc.Localize("txt_GMA_Exp_AU"), Starter.loc.Localize("txt_GMA_Exp_AU"))
                wait for Msgbox_result (r As Int)
            End If
        Loop

- Start (First Run) is all o.k.
- if User dont select a Radiobutton (rbtn....checked) and Click on Start the Loop run a second (while rbtn_check <2)
- on this Point the Code Crash (at DialogPanel.AddView(pnl.......)

thanks for help

DialogPanel.AddView(pnl, 0, 0, DialogPanel.Width, DialogPanel.Height) 'pnl is a Panel

Add a

pnl.RemoveView

after this line

But it looks like you are adding the same panel each time. Maybe this is the issue.

Add a

pnl.RemoveView

after this line

it works not correct. No abort, but the Pnl is not show.
I will test a other place.

EDIT: before Loop it Works in Test Projekt

But it looks like you are adding the same panel each time. Maybe this is the issue.

Yes, i do that.
is there a better solution??

There 4 Radiobuttons in 2 Groups. Each Grupe must have a selection (Rbtn 1 or 2)

 

[Erel]

Don't use the same panel. I'm not sure why you need a panel at all. Just load the layout to DialogPanel.

 

[mw71]

The panel / layout is code generated

I added a small project for testing.
With (comment) old it works.
Test to add elements to DialogPanel does not work (I think it's also a "Panel" problem)

rbtn_ref_ja and rbtn_ref_nein are one group.
colored_port_ja and colored_port_no are the other group.
In each group, 1 button (Yes or No) must be selected.

 

[Erel]

The panel / layout is code generated

This is a mistake.

As I previously wrote you should create a new panel each time. If you use the designer to create the layout then it will be very simple.
