NodeFocusChanging fires when Focused property of some node becomes changed (to true or to false).
If you want to handle new node focusing use following code:
[c#]
private void InitGrid()
{
//code in flygrid initialization
this.dataGrid.NodeFocusChanging += new NodeBoolHandler(dataGrid_NodeFocusChanging);
}
private bool dataGrid_NodeFocusChanging(object sender, NodeBase node)
{
if (node.Focused == false)//node becomes to be focused
{
//here your code///
}
return true;
}
