    Hi,

    I have a problem with the ComboBox in a Grid Editor Template. The options in the ComboBox are filled by cascading from a DropDownList in the Editor Template which works great. However, if I Update one of the rows I've already added, and choose an option in the DropDownList that results in zero options for the ComboBox and click Update from the pop up without typing anything, the Update event of the Grid posts the old selected value. How can I ensure that the Update event will post the new empty value from the ComboBox?

    Hello Mark,

    Cascading a ComboBox from a DropDownList is currently not supported out of the box. I would recommend removing the ComboBox's CascadeFrom option and use the VendorId's change event to call the ProductName's dataSource.read() method. You could also use the change event handler to enable or disable the ComboBox, thus emulating the cascading functionality.
