How to set keyboard focus to a specific DataFormField?

[Jeff]

I have a telerik:RadDataForm with an EditTemplate.

In that template I have a number of telerik:DataFormDataField's defined.

What I would like is to have the keyboard focus automatically set to one of these fields (not the first), when I do a BeginEdit().

How?

Hello Jeff,

In order to achieve the desired behavior, you can handle RadDataForm's BeginningEdit event, like so:

public MainWindow()
{
    InitializeComponent();
    this.DataForm.BeginningEdit += DataForm_BeginningEdit;
}

private void DataForm_BeginningEdit(object sender, System.ComponentModel.CancelEventArgs e)
{
    var dataForm = sender as RadDataForm;
    var fields = dataForm.ChildrenOfType<DataFormDataField>();
    var field = fields.FirstOrDefault(x => x.Name == "Est");
    var textBox = field.FindChildByType<TextBox>();
    textBox.Focus();
}

Please let me know whether such an approach would work for you.

When I try this, dataForm.ChildrenOfType<DataFormDataField>() returns null.

Hello Jeff,

I'm attaching a sample project where the ChildrenOfType method returns the expected result.

Could you please have a look at it and let me know whether it differs from the setup you have at your end in any way?

Thank you in advance for your cooperation.
