Within code behind, it is real easy to reset the combobox to a selected value of nothing combobox.selectedIndex = -1, I have tried multiple things to recreate this within javascript but can not seem to accomplish the same thing.
Does anyone know how to do this within javascript?
Thank you

I am putting the solution from the support case here so that everyone can find it in a search.
You can clear the selection and value by using the setValue method of the WebCombo. It would look something like this:var combo = igcmbo_getComboById("<%=WebCombo1.ClientID %>");combo.setValue(null);
This doesn't work. It sets the displayed text value in the drop down to "null". (And I don't have an option for "null).
Correction: This doesn't work if Editable property is set to true. It does not display the "null" text value if Editable property is set to false.
Try this:
var combo = igcmbo_getComboById("<%=WebCombo1.ClientID %>");if (combo.Editable) { combo.setValue("");}else { combo.setValue(null);}
