Set focus in runtime ?

[Per]

Hi!

I have a main form containing MDI forms.
When I load my MDI form (containing a multi column drop down control), I want the drop down control to have focus so I can start writing in it without first having to selected it.
(Im using a multi drop down control as a search input field)

Can this be done ?

Hello Per,

Thanks for writing and for your question.

Yes, it is possible to set the focus on the RadMultiColumnComboBox when the MDI Child Form is shown so that you can immediately start typing. Take a look at the code snippets below:

public partial class Form1 : RadForm
    {
        public Form1()
        {
            InitializeComponent();
        }

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

            this.IsMdiContainer = true;
            ComboMdiChild child = new ComboMdiChild();
            child.MdiParent = this;
            child.Show();
            child.Shown += new EventHandler(child_Shown);
        }

        void child_Shown(object sender, EventArgs e)
        {
            ComboMdiChild child = sender as ComboMdiChild;

            if (child != null)
            {
                child.ComboBox.Focus();
            }
        }
    }

This is the code of my MDI Parent form. In the Load event of the parent I create an instance of the ComboMDIChild class which represents my MDI Child form. This class has a ComboBox property which exposes the RadMultiColumnComboBox control. I subscribe for the Shown event of the MDI Child and in its Event Handler I call the Focus method of the RadMultiColumnComboBox control.

Here is the code of the ComboMdiChild class:

public partial class ComboMdiChild : RadForm
    {
        public ComboMdiChild()
        {
            InitializeComponent();
        }



        public RadMultiColumnComboBox ComboBox
        {
            get
            {
                return this.radMultiColumnComboBox1;
            }
        }
    }

I hope this is helpful.
