Hello, Connor,

You are right, please excuse me for this. You can use a Boolean variable to workaround it:

bool Bool;
private void RadMultiColumnComboBox1_TextChanged(object sender, EventArgs e)
{
    if (!Bool)
    {
        this.radMultiColumnComboBox1.SelectedIndex = -1;

    }
    Bool = true;
}

Hi Nadya,

I have tested your workaround and believe that it does not work.

This resolves the defaulting issue, however it means that you cannot then select then a value from the combobox normally.

Thanks,
Connor

Hi, Conor,

Currently, you can use the following workaround:

private void RadMultiColumnComboBox1_TextChanged(object sender, EventArgs e)
{
    this.radMultiColumnComboBox1.SelectedIndex = -1;
}
