Hello Ricric,

You can achieve this by subscribing to the events of the hosted text box. I am posting you an example that demonstrates this:
public partial class CommandBarSample : Form
{
    private bool isEntering;
 
    public CommandBarSample()
    {
        InitializeComponent();
 
        this.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl.Enter += new EventHandler(CommandBarSample_Enter);
        this.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl.MouseDown += new MouseEventHandler(HostedControl_MouseDown);
    }
 
    void HostedControl_MouseDown(object sender, MouseEventArgs e)
    {
        if (this.isEntering)
        {
            this.isEntering = false;
            (this.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl as TextBox).SelectAll();
        }
    }
 
    void CommandBarSample_Enter(object sender, EventArgs e)
    {
        this.isEntering = true;
        (this.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl as TextBox).SelectAll();
    }
 
}

I hope this is useful. Feel free to ask if you have any additional questions.

Best wishes,

Hi Ricric,

Here is the same code, translated into VB:
Public Partial Class CommandBarSample
    Inherits Form
    Private isEntering As Boolean
 
    Public Sub New()
        InitializeComponent()
 
        AddHandler Me.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl.Enter, AddressOf CommandBarSample_Enter
        AddHandler Me.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl.MouseDown, AddressOf HostedControl_MouseDown
    End Sub
 
    Private Sub HostedControl_MouseDown(sender As Object, e As MouseEventArgs)
        If Me.isEntering Then
            Me.isEntering = False
            TryCast(Me.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl, TextBox).SelectAll()
        End If
    End Sub
 
    Private Sub CommandBarSample_Enter(sender As Object, e As EventArgs)
        Me.isEntering = True
        TryCast(Me.commandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.HostedControl, TextBox).SelectAll()
    End Sub
 
End Class
