Enable RadButton when item from RadCombobox is selected

[Darrin]

I have a radbutton on my form that is disabled.

I have about 10 RadComboboxes on the same form.

I'm trying to enable the Radbutton once a Value is selected from the any of the comboboxes.

Can't seem to get this working.

Any help would be appreciated.

 

<telerik:RadComboBox ID="ddl1" runat="server" Width="90px" Skin="Vista" Font-Names="Verdana" Font-Size="Small" ZIndex="8900" OnClientDropDownOpening="Enable_Save">
                        </telerik:RadComboBox>

 

<script type='text/javascript'>
function Enable_Save()
{
    if(document.getElementById("ddl1").value!="")
        document.getElementById("b1").disabled=false;
    else
    document.getElementById("b1").disabled=true;

}

</script>

Hello Darrin,

Instead of using OnClientDropDownOpening subscribe the ComboBoxes to the OnClientSelectedIndexChanged event:

<telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
</telerik:RadComboBox>

in the event's handler get the button and call its set_enabled() client-side method passing true in order to enable it:

function OnClientSelectedIndexChanged(sender, eventArgs) {
    var button = $find("<%=b1.ClientID %>");
    button.set_enabled(true);
}
