Self Reference Hierarchy only seems to work on MasterTemplate. I would like to have the following hierarchy:
Group
> Category
> Category
> Product
Where category can have any number of levels. If I make MasterTemplate the categories and then AddSelfReference, it works fine, but if I have groups at the MasterTemplate level and then have a CategoryTemplate and AddSelfReference I only get one level of categories.
GroupCategory relation is Group.id = Category.groupId
I have tried this:
this.radGridView1.Relations.AddSelfReference(this.CategoryTemplate, "id", "parentId");
and
this.radGridView1.Relations.AddSelfReference(this.radGridView1.Templates[0], "id", "parentId");
and these both show only one level of categories.
With categories at the root (MasterTemplate) this works:
this.radGridView1.Relations.AddSelfReference(this.radGridView1.MasterTemplate, "id", "parentId");
I get several levels of categories.

Hi:
I'm trying to use the ListControl. I have two on my form and I use the DragDropManager to join them. However, it seems that I am unable to get any of the events associated with drag and drop to fire. I've created them using the properties list and everything in code is correct. Yet if I put a break point in the dragdrop event, it never gets there. (allow dragdrop is set to true).
Anyone know what gives ?
Thanks,
Ken

I have a custom Appointment dialog because the one I use is very different from the default. I'm interrupting the default dialog by using e.cancel in RadScheduler1_AppointmentEditDialogShowing, and then displaying my custom form. This works great for new appointments but I need it to populate existing appointments when they are selected in the calendar. How can I retrieve the SQL ID of the appointment being selected? I need to pass this value to my custom form.

Hello,
I would like to use the functionality of the RadTextBox and SpellChecker, but I also need to use my framework's databinding interface. So I created a subclass of the RadTextBox control and implemented the interface for binding.
After calling spellChecker1.Check(sfRadTextBox1) I get the following error:
Why isn't it picking up on the fact that the base class has the IControlSpellChecker interface implemented arleady?
Can someone please tell me what I'm doing wrong here and what I should be doing to get this working.
Thank You,
Govinda

Hello
In a Gridview, is there a way to use the same kind of tool than ".IsOdd", but applied to a particular cell's data? In short, I want the row color to change everytime the value in a particular column changes. Said columns happens to be my "ORDER BY" column.
