The CellEditorInitialize event isn't raised for edit cells that contain custom editors defined via templates.

Hi,
I'll still wait for your comment but I managed to create an event handler in the ITemplate class that handles the databinding event for each control in the class.
        void DateEditorBindingsEventHandler(object sender, EventArgs eventArgs)
        {
            GridViewDataItemTemplateContainer container = ((ASPxDateEdit)sender).NamingContainer as GridViewDataItemTemplateContainer;
            ((ASPxDateEdit)sender).Value = container.Text;
        }
       protected void AddDateEdit(ASPxGridView gv, Control container, String fieldName, String dataType, bool required, bool withTime)
        {
            ASPxDateEdit de = new ASPxDateEdit();
            GridViewEditItemTemplateContainer editingContainer = (GridViewEditItemTemplateContainer)container;
            int key = Convert.ToInt16(editingContainer.KeyValue);
            de.ID = String.Format("{0}_{1}", fieldName, dataType);
            if (withTime) { de.EditFormat = EditFormat.DateTime; }
            if (required) { AddRequiredAttributes(de); }
            de.DataBinding += new EventHandler(DateEditorBindingsEventHandler);
            container.Controls.Add(de);
        }

Hi Graham:
The CellEditorInitialize event is raised for the standard column editors only.
If you have a custom editor in a template container, then we recommend using its Init event.
The following article describes this approach in detail:
The general technique of using the Init/Load event handler
Thanks

Hello,
I'm afraid the link provided in the answer does not satisfy my issue.
I cannot in-advance create the control init/load event handlers at design time because the controls are created at runtime.
I was successful in my implementation of creating handlers in my ITemplate based class but want to know if there exists other grid based API's like the CellEditorInitialize event to update the value of an editor control located within a custom column when the grid row is edited. When I assign a value to a custom column control, which event should be used in the ITemplate method body?
ASPxTextBox tb = new ASPxTextBox();

1. tb.DataBinding += new EventHandler(TextEditorBindingsEventHandler); or
2. tb.Init += new EventHandler(TextEditorBindingsEventHandler); or
3. tb.Load += new EventHandler(TextEditorBindingsEventHandler);

Hello Graham,
As Kate said, when you use custom templates, the grid won't raise the ASPxGridView.CellEditorInitialize event for them.
> When I assign a value to a custom column control, which event should be used in the ITemplate method body?
When you create an object, implementing the ITemplate interface, this doesn't mean that all controls are created. The method that can be interpreted as the ASPxGridView.CellEditorInitialize event handler is the InstantiateIn method of your template class, which is raised every time the grid creates template controls.
Thanks,
