Please try to add following code in the OnAfterItemSelected client-side event of the parent WebCombo, for example cbo1 (the parent WebCombo of cbo2).

function onCbo1SelChange(controlId) {
    var cbo1 = ISGetObject(controlId);
    var cbo2 = ISGetObject("cbo2");
            
    cbo2.SetText("Nancy");
    cbo2.LoadValue();

    return true;
}

WebCombo provides a client-side method to set selected row in bound WebCombo, as shown in the snippet code above. The first step is to configure the WebCombo text by executing SetText(string) method. After set the text of WebCombo, please remember to invoke LoadValue() method, in order to instruct WebCombo to fetch the value of the correspond inserted text from the server. the LoadValue() method is required for bound mode WebCombo, because when a new text is set, the WebCombo doesn’t have the related value in client-side since the data has not been loaded. This method is not required for unbound mode.

Hope this helps.

Yudi,

"cbo2.LoadValue();" is what I didn't know about. It fixed the problem.

Thank you!

Glad to hear that the LoadValue() method helps.
