I wasn't able to replicate this behaviour using the DataSet Browser sample project. If you can replicate this behaviour in a small sample project and send us zipped copy to support@infralution.com (with step by step description of what you are doing) then we will take a closer look at the issue.

Thanks for the sample. There is a minor issue in the way Virtual Tree is handling "Enter" key presses when EditOnKeyPress is set to true. In this case Virtual Tree is sending opening the first editor and then sending it the "Enter" key press - which in turn causes the editor to close.
The workaround is to handle the KeyPress event and if the character is an enter mark the event as handled - this will prevent VirtualTree from further handling the event and prevent the behaviour. eg
| Code: | private void _virtualTree_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == 13)
{
e.Handled = true;
}
} |
We will fix this in the next release.
| Quote: | | Out of interest is there any way to disable the default key commands (enter to edit, arrow keys and tab to navigate when the modifier keys are down? – for example I wanted to use ctrl-up/down to move siblings up and down and also shift and ctrl enter to do add child / sibling) |
To handle the enter, escape and arrow keys you need to override the ProcessCmdKey method or the sub-methods that it calls
| Code: | ProcessNormalCmdKeys // called when there is no active editor
ProcessEscapeCmdKey
ProcessEnterCmdKey
ProcessRightCmdKey etc
ProcessEditCmdKeys // called when there is an active editor
ProcessEditEscapeCmdKey
ProcessEditEnterCmdKey
ProcessEditRightCmdKey etc |
