FIX. RadTextBoxControl/ RadAutoCompleteBox - ArgumentNullException when appending text
To reproduce:

public Form1()
{
    InitializeComponent();
    this.radAutoCompleteBox1.AppendText("abc;");
}

Workaround: append the text in the Form.Load event.

private void Form1_Load(object sender, EventArgs e)
{
    this.radAutoCompleteBox1.AppendText("abc;");
}

Hi Stefan,

thanks for the reply. 

Problem was/is I would like to do everything in the constructor... but it works like you suggests :)

Hi Steffen,

The workaround should be applied in the Form.Load event. You should subscribe to it and instead of appending the text in the form's constructor, you should append it in the Load event handler. 

I hope this helps.
