Focus floating toolwindow on form load

[Arun Kumar]

How do I focus control inside toolwindow on form load ?

Hi Arun Kumar,

To focus a child control in ToolWindow or any parent window, you must call Focus method in the Load event. Here is a simple example:

public partial class DockForm5 : Form
{
    private TextBox textBox;

    public DockForm5()
    {
        InitializeComponent();

        ToolWindow tool = new ToolWindow("123");

        ComboBox box = new ComboBox();
        box.Items.Add("1");
        box.Items.Add("2");
        box.Items.Add("3");
        tool.Controls.Add(box);

        RadDropDownList list = new RadDropDownList();
        list.Items.Add("1");
        list.Items.Add("2");
        list.Items.Add("3");
        list.Location = new Point(50, 50);
        tool.Controls.Add(list);

        RadDateTimePicker picker = new RadDateTimePicker();
        picker.Location = new Point(50, 90);
        tool.Controls.Add(picker);
        radDock1.DockWindow(tool, DockPosition.Left);

        tool = new ToolWindow("333");
        textBox = new TextBox();
        tool.Controls.Add(textBox);

        radDock1.DockWindow(tool, DockPosition.Bottom);
        radDock1.AddDocument(new DocumentWindow("test"));
    }

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);

        textBox.Focus();
    }
}

I hopo this helps.

Hi Julian Benkov,

Thanks for your reply.

I have floating toolwindow. In form load event, I use the RadDock.FloatWindow method to show the toolwindow. It shows the window on form load but it is not focused. Only if I click the window it gets activated. I want the window activated by default. So I can focus the textbox placed inside the toolwindow. How do I do that ?

Hello Arun,

For this functionality you can use the Shown event of From instead of the Load event. Here is a simple example:

protected override void OnShown(EventArgs e)
{
    base.OnShown(e);

    radDock1.FloatWindow(toolWindow);
    toolWindow.FloatingParent.Activate();
}

Let me know if you need further assistance.
