On my page, I have added a WebCombo(control with the following settings: ComboTypeAhead = Suggest; Editable =True;and EnableXmlHttp = true.
My intention is for this Combo to fetch its data asynchronously only when needed. However I can't seem to figure out how to get the combo to do this. It always fires the InitializeDataSource event on the first page load. I would think that it should fire InitializeDataSource only when the data is needed (such as when the user starts typing in the control or clicks on it to dropdown).
Is it possible to get the behavior I described? It seems to be a waste to always get the data.
I have version 8.2.20082.1000. Thanks for any info.
WebCombo needs to raise InitializeDataSource on the initial page load so that it knows what data to display upon initial rendering. That way, the first set of rows for the combo are available immediately.
