javascript unable to find control inside usercontrol edit form

[Vinh]

Hi,

I'm currently using the usercontrl edit form and I would like to have this function in javascript
if the value of the rdbBillable= 1
then enable some of the textboxes
else
disable the text boxes

The problem is when I place the javascript inside the ascx page, the it complaints that there is no javascript (Microsoft JScript runtime error: Object expected), but then if I put in the aspx page, it also complaint for this line

 

radio = $find(

'<%= rdbBillable.ClientID %>');

 

 

Compiler Error Message: CS0103: The name 'rdbBillable' does not exist in the current context.

Thanks

Hi Vinh,

Try putting this javascript in your user control and wrap it in a RadScriptBlock. Note that radio button with ID rdbBillable must be visible in the user control, i.e. it should not be inside another NamingContainer in the user control.

I tried that too but still able to.  Do you have a sample that you can read a control from the user control edit form for the RadGrid?

Thanks

Hi Vinh,

Sure, I have attached a test page with a user control. The user control demonstrates 2 scenarios:

1. Getting a client component by its ClientID rendered with an inline expression (of the form <%= %>)
2. Getting a client component by its server id using $telerik.findControl()

Hello Abdul,

Check whether you have used same name when calling the client side event and in the client event handler.

ASCX:

<telerik:RadTextBox ID="RadTextBox1" runat="server" Width="200px">
</telerik:RadTextBox>
<input type="button" value="get this textbox from its client ID" onclick="getWithServerID(this)" />

Java script:

<script type="text/javascript">
    function getWithServerID(button) {
        var container = button.parentNode;
        var textBox = $telerik.findControl(container, "RadTextBox1");
        textBox.set_value("ClientID: " + textBox.get_element().id);
    }
</script>

Thanks,
Princy.
