copied!<p>You want to create your own column</p> <pre><code>using System.Windows; using System.Windows.Data; using Telerik.Windows.Controls; using Telerik.Windows.Controls.GridView; using System; namespace Inspect { public class DateTimePickerColumn : GridViewBoundColumnBase { public TimeSpan TimeInterval { get { return (TimeSpan) GetValue(TimeIntervalProperty); } set { SetValue(TimeIntervalProperty, value); } } public static readonly DependencyProperty TimeIntervalProperty = DependencyProperty.Register("TimeInterval", typeof(TimeSpan), typeof(DateTimePickerColumn), new PropertyMetadata(TimeSpan.FromHours(1d))); public override FrameworkElement CreateCellEditElement(GridViewCell cell, object dataItem) { this.BindingTarget = RadDateTimePicker.SelectedValueProperty; RadDateTimePicker picker = new RadDateTimePicker(); picker.IsTooltipEnabled = false; picker.TimeInterval = this.TimeInterval; picker.SetBinding(this.BindingTarget, this.CreateValueBinding()); return picker; } public override object GetNewValueFromEditor(object editor) { RadDateTimePicker picker = editor as RadDateTimePicker; if (picker != null) { picker.DateTimeText = picker.CurrentDateTimeText; } return base.GetNewValueFromEditor(editor); } private Binding CreateValueBinding() { Binding valueBinding = new Binding(); valueBinding.Mode = BindingMode.TwoWay; valueBinding.NotifyOnValidationError = true; valueBinding.ValidatesOnExceptions = true; valueBinding.UpdateSourceTrigger = UpdateSourceTrigger.Explicit; valueBinding.Path = new PropertyPath(this.DataMemberBinding.Path.Path); return valueBinding; } } } </code></pre> <p>That is how you create a custom column. If you modify the CreateCellEditElement Method it will let you create custom cells how you like. You should even be able to detect the row number</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
