I am using a BindingList object as my datasource and I would like to use an image list to display images in my treeview. I looked for an ItemDataBound event or something similiar, but I did not see it. I tried to use the DrawNode Event but I would get an error saying that the ImageIndex Property could not be updated because the treeview was in lock mode or something along those lines. How do you suggest adding images when databinding?
Thanks.
Thanks.

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);

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.
