WinTree checkboxes

Del posted over 15 years ago

Hi,I am using an Infragistics.Win.UltraWinTree.UltraTree control which has checkboxes next to each node. Is there a way of displaying the checkbox but blocking users from changing its checkstate? i.e. mimicking the functionality of a standard checkbox where AutoCheck has been disabled. If a user clicks the checkbox nothing happens other than the node is selected.I am currently intercepting the _BeforeCheck event and cancelling it. This has the overall affect of not allowing users to change checked state but causes the check to flicker on or off briefly between the mouse down and mouse up.Regards

I was not able to reproduce the flicker issue you described here; you might want to log an incident with Developer Support so you can provide the details ncessary to reproduce that behavior.

Hi Brian,

I am running the following:
private void tree_BeforeCheck(object sender, BeforeCheckEventArgs e)
{

e.Cancel = true;

}

The problem is that at this point the tick has already been placed in the checkbox before the this event is alling the cancel.

Regards

I must have misinterpreted your use of the word "flicker". If you are using the Office2007 glyph style for the checkboxes, the issue you describe might be a bug that was recently reported. You should log an incident with Developer Support so that you are notified when a fix becomes available.
