    Hi,

     How can i validate resource of Type Dropdown so that it should not apply the 0 index value for insertion. i have a resource Task whose values are shown in dropdown box for insertion or updation. it shows value at top with '-' or blank value. i need to validate that value so that it should be selected or there is any other way like blank value never shows up at the top. i am sending screen shot or resource  for better understanding,



    Thanks

    If you are handling AppointmentInsert in the codebehind, set e.Cancel = True to abort the insert if validation fails.

    Thanks for the Reply Dan...... But can't we validate it on the client side or we can just remove the zero index item and directly Display the first key item in dropdown. it will be good if we can validate on client side or there some other option.
    pls reply if any one can help with this....


    Thanks

    Hello Kevin,

    Yes, you can make selected item check on the client-side.

    I made an example for you showing how to modify the ComboBox controls inside the AdvancedForm of the Scheduler using JavaScript.

    Attached is a .zip file containing only the .aspx file of the example.

    Hope this helps.

    Best wishes,

    Hello Kevin,

    You can access the resource combobox in FormCreated and set its SelectedIndex property from code behind. Here is a kb article that will help with this task - http://www.telerik.com/support/kb/aspnet-ajax/scheduler/how-to-access-controls-in-the-advanced-form.aspx.
