    When I have dynamically added a new column to RadGridView which type is GridViewCheckBoxColumn

    radGridView1.Columns.Add(new GridViewCheckBoxColumn() { DataMemberBinding = new Binding("HasOrders"), UniqueName = "HasOrders3", Header = "Has Orders3"
        , AutoSelectOnEdit = true
        , EditTriggers = GridViewEditTriggers.Default | GridViewEditTriggers.CellClick

    I will get the cheched status from CellEditEnded - event

    private void radGridView1_CellEditEnded(object sender, GridViewCellEditEndedEventArgs e)
        if (e.Cell.Column.UniqueName == "HasOrders3")
            textBox3.Text = ((CheckBox)e.EditingElement).IsChecked.ToString();

    But this CellEditEnded - event triggers only when I leave the cell or press enter/tab key.

    If I stay on that cell and click the checkbox I cannot catch the cheched change event? How can I do that in?

    Hello Auvo,

     Generally, you can define CellTemplate for a column, add a CheckBox inside and handle its Checked event:

    <telerik:GridViewDataColumn DataMemberBinding="{Binding IsChampion}">
                            <CheckBox IsChecked="{Binding IsChampion, Mode=TwoWay}" Checked="CheckBox_Checked"/>

    Furthermore, in your particular case,  you could bind the textBox3 Text property directly to the "HasOrders3" bound property. That way once the state of the CheckBox is changed(i.e. the value of "HasOrders3" has changed), the text in the text box will be updated immediately.

    If I use the CheckBox inside solution , how can I know witch row was selected on the handler. 
    In my case the Checkbox is Unbound and used to alter the content of another cell.

     You could find the parent row for the "checked" CheckBox like so:

    private void CheckBox_Checked(object sender, RoutedEventArgs e)
        var parent = (sender as CheckBox).ParentOfType<GridViewRow>();

    Does this work for you?

    There will be no fix for that?

    Hello Peer,

    This behavior is expected with the RadGridView control. Changing the selected value in the checkbox of the column doesn't automatically commit the cell change, thus you have to trigger it somehow. For example, by pressing another cell. This is why if you want to alter the default behavior you will need to customize the column's setup. One way to do this is to use the Didie's approach from one of the previous replies here.
