[Solved] get_value not working

[Baatezu]

I'm getting an error of "[control].get_value is not a function". I've been trying to hunt down the proper javascript... but everything I've found suggests that the get_value should work.

<script type="text/javascript">
 function PreventPostback(sender, eventArgs)
 {
    var txtGrossCommission = document.getElementById('<%= radNumCommissionValue0.ClientID %>');
    var txtTypeValue = document.getElementById('<%= radNumCommissionValue.ClientID %>_text');
    var ddlType = document.getElementById('<%= radComboType.ClientID %>_ClientState');
    var txtCommission = document.getElementById('<%= radNumCommissionAmount.ClientID %>');

    var re1 = new RegExp(".+\"value\":\"");
    var re2 = new RegExp("\",\"text\".+");

    var clientValue = ddlType.value.replace(re1, "").replace(re2, "");

    alert(sender.get_value());
    alert(txtGrossCommission.get_value());

    if(clientValue == "percent")
    {
        txtCommission.set_value(txtGrossCommission.get_editValue() * txtTypeValue.get_editValue()/100);
    }
    else if(clientValue == "flatrate")
    {
        txtCommission.set_value(txtTypeValue.get_editValue());
    }
 }
</script>

The first alert works fine; the second alert fails. The Firefox Error Console gives me the error - "txtGrossCommission.get_value is not a function".

I'm obviously missing something - No idea what though. Any help would be great.

Use $find AJAX function to get control client object. Look at the ASP.NET AJAX docs or just ask Google for more info about the function.

var txtCommission = $find('<%= radNumCommissionAmount.ClientID %>');

Many Thanks - Fixed it perfectly.

I think I tried the $find earlier - but I musta had a few other things 'wrong' so it didn't solve it like it did this time.
