    Hi,

     

    In My Application I have Cascading combo box, User is selecting one combo box and based on selection of first combo box second combo box  will get populated,  now I am storing those values to database and I want to set the value of combo box from Java script to allow user to update those values. To do so how can I set the text of combo box having LoadOnDemand from javascript. e.g. My combobox will have the items as

    Employee ID    EmployeeName

    1                          ABC

    2                          PQR

    now I am getting PQR from database and I want to set it to Combo box having PopulateOnDemand Property = true. I tried to create the object of Combobox in JavaScript and then tried with FindItemByText property, but since combo box is configured to Load on demand it is not able to find anything and not able to set the value.

    Please let me know how to do it using JavaScript.

    Hello Rahui,

    Indeed the RadComboBoxItems collection is not accessible at server-side, but it is at client-side. You can use the findItemByText() at client-side and set the item as selected:

    $find("RadComboBox1").findItemByText("PQR").select()
