Hi

Can you please add a SelectedItem property - with that one can get the selected item outside the item click event. I am assuming this can use the .SelectedIndex property is such has a get and a set.

eg.

Dim y As String = SD_xComboBox1.SelectedItem

and perhaps

SD_xComboBox1.SelectedItem = "ABC"

Only if possible.

Use ByValue.

SD_xComboBox1.ByValue = "ABC"

 

[Star-Dust]

Dim y As String = SD_xComboBox1.GetItem(SD_xComboBox1.SelectedItem)

 

[Star-Dust]

I will update the names of the methods that are misspelled by mistake

        Dim Ph As Phone
        ' B4XPage
        Ph.HideKeyboard(B4XPages.GetManager.GetTopPage.Parent.NativeType)
        ' Normal
        Ph.HideKeyboard(Activity)
    #else if b4i
        ' B4XPage
        Root.As(NativeObject).RunMethod("endEditing:", Array(True))
        ' Normal

This is a debugger warning. You can ignore it. It means that the event will be postponed instead of running immediately.

Not exactly like that. Do you want to have rounded edges?

 

[Dadaista]

Not exactly like that. You can't have rounded edges in this version
