    Hi,

    I am using cellvaluechanged event for my grid for column total validation. In that method I am using “oldvalue” to restore the previous data incase if the validation fails.

    Now when we multiselect the rows and click on delete key (using keyboard), the cellvaluechanged event is called but we are getting an error like “oldvalue” is undefined. And we are getting stuck there.

    Can you please help on this.

    Regards,
    SSP

    Hello SSP,

    We have tested the following example with the latest version of jQWidgets (3.3.0) and oldvalue always shows the correct value. Do you experience any issues with it?
