RadAutoCompleteBox: CaretIndex is not up to date during TextChanged

[Giovanni]

I want to obtain current editing text on a RadAutoCompleteBox.
For example, on the attached screenshot I want to obtain the string "ru".

Is there any property to read that text?

I tried to obtain this text parsing current text, during text change, with following code:

Private Sub RadAutoCompleteBox1_TextChanged(sender As System.Object, e As System.EventArgs) Handles RadAutoCompleteBox1.TextChanged
    If Me.RadAutoCompleteBox1.CaretIndex > 0 Then
        ' Obtain current editing text
        Dim pos As Integer = Math.Max(0, Me.RadAutoCompleteBox1.Text.LastIndexOf(";", Me.RadAutoCompleteBox1.CaretIndex) + 1)
        Me.TextBox1.Text = Me.RadAutoCompleteBox1.Text.Substring(pos, Me.RadAutoCompleteBox1.CaretIndex - pos).Trim()
    End If
End Sub

But the problem is that when the textchanged event fires, CaretIndex is not up-to-date: it point to the previous text position.
Thank you for any help.

Hello Giovanni,

Thank you for writing.

Presently, the CaretIndex position in RadAutoCompleteBox does not obey the text length of the control due to its object model. I recommend using the following code snippet to achieve the desired scenario:

Private Sub RadAutoCompleteBox1_TextChanged(sender As System.Object, e As System.EventArgs)
    Dim navigator As AutoCompleteTextNavigator = TryCast(Me.RadAutoCompleteBox1.TextBoxElement.Navigator, AutoCompleteTextNavigator)

    Dim start As TextPosition = navigator.GetPreviousEditablePosition(navigator.CaretPosition)
    Dim [end] As TextPosition = navigator.GetNextEditablePosition(navigator.CaretPosition)

    Dim text As String = Me.RadAutoCompleteBox1.TextBoxElement.ViewElement.GetTextRange(start, [end])
End Sub

I hope this helps.
