[Solved] RadCombo findItemByValue

[James]

Hi,

I've been upgrading my combo from the standard radcontrols to Prometheus, but it's complaining in the client script that findItemValue doesn't exist.

Is there an alternative way to find an item in the combo based on either a value or text? I've had a look at the demos and documentation but couldn't find anything

Regards

Bobby

Hello Bobby,

The names of the javascript methods are: findItemByValue and findItemBytext.

I suggest you check the following article:

Migrating RadComboBox Classic to RadComboBox Prometheus 


Hope this helps.

Hi Again,

Still no luck. Below is some sample code. It throws an "object doesn't support this property or method" exception when it tries to call the "findItemByValue" method.

Hi Bobby,

You should obtain a reference to the ComboBox using this syntax:

var rcbCombo = $find("<%= RadComboBox2.ClientID %>");

instead of 

var rcbCombo = document.getElementById("<%= RadComboBox2.ClientID %>");


I think you may find useful the help topics under Controls / RadComboBox / RadComboBox Client-Side /


Kind regards,

Thanks for your prompt responses.
