Hi Samuel,
Thanks for your interests in Syncfusion products.
You can make use of the BeforeSelect event to prevent a node from being selected when setting enabled as False. Kindly make
use of the code snippet for how to set the args value as canceled one.
void treeViewAdv1_BeforeSelect(object sender, Syncfusion.Windows.Forms.Tools.TreeViewAdvCancelableSelectionEventArgs args)
{
if (args.SelectedNodes[0].Enabled == false)
{
args.Cancel = true;
}
}
We are also sending you a simple sample as per your requirement. Kindly download it from the below location.
