I want to add root node to self referenced database binded RadTree View.
RadContextMenu contextMenu = new RadContextMenu();
RadMenuItem addRootNodeItem = new RadMenuItem("New Node");
addRootNodeItem.Click += addRootNodeItem_Click;
contextMenu.Items.Add(addRootNodeItem);
radTreeView1.RadContextMenu = contextMenu;
void addRootNodeItem_Click(object sender, EventArgs e)
{
RadTreeNode RootNode = new RadTreeNode("New Node");
radTreeView1.Nodes.Add(RootNode);
I tried above code but which returns error Object reference not set to an instant of of an object.
Any other method to do this?
RadContextMenu contextMenu = new RadContextMenu();
RadMenuItem addRootNodeItem = new RadMenuItem("New Node");
addRootNodeItem.Click += addRootNodeItem_Click;
contextMenu.Items.Add(addRootNodeItem);
radTreeView1.RadContextMenu = contextMenu;
void addRootNodeItem_Click(object sender, EventArgs e)
{
RadTreeNode RootNode = new RadTreeNode("New Node");
radTreeView1.Nodes.Add(RootNode);

I'm binding GridView to a datasource referencing a dataset with filtering enabled. I understand the filtered rows are in the ChildRows collection - but how do apply that to the underlying datasource so I can remove the filtered records?

My project contains several parameters that can be used to filter the displayed appointments.
Examples are:
1. Guest Name
2. Employee Name
3. Appointment Category (Spa, Sports, etc.)
4. Location (Spa room 1, Tennis Court 1, Stable 1, etc.)
5. Appointment Type (massage, tennis, horse back riding, etc.)
I would like to provide a combobox for each parameter and allow the user to select the filters. Is there a method, similar to filtering a bindingsource?
Also, Is there any method to refresh the appointments? If computer 1 is displaying the scheduler and a new appointment is made at computer 2, I would like computer 1 to be able to click a "refresh" button and see the changes to the database.

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 ?
