I have a RadTextBoxElement control within a RadRibbonBarGroup within a RadRibbonBar.
The problem is that when I click on the TextBoxElement and drag to select some text, if the mouse is move outside of the TextBoxElement and over an adjacent RadButtonElement, the ButtonElement click event fires when the mouse button is released.
Is there any wat to prevent this? The problem is that the user will casually drag across to select a bunch of text but won't necessarily be careful not to move the mouse out of the TextBoxElement control.

This is somewhat complicated for me to explain (q3 2012) .Pardon me if it my error
I had added radScheduler and Navigator.Binded it.then bined with a database SchedulerData.mdb
done every step as per latest help file.Then i had created a button and write the update script provided in the help.
Added new appointments it saves fine.
Now in the DayView/week view/Month view i tried to resized an appointment using mouse(time is in the positive direction that is this time to future time)It resized and shown perfectly.But after hilting the update button it will regain it's previous state.the problem is not present in time line view also if i manually in put schedule time there will be no error.Did i forget some thing or is it an error ?

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.
