Thanks in advance for any attention my issue gets. I hope this is the right area to post it.

I’ve been using the Infragistics  UltraWebGrid Version 2.0.5000.17 for some years. My company have unfortunately not got round to upgrading the asp.net 1.1 project over the years for various reasons.  We are now in a position where we are upgrading from asp.net 1.1 to hopefully asp.net 4.0.

I have addressed many issues but have 1 remaining.

The Ultrawebgrid puts code to call igtbl_submit into the aspx page in a webform_onsubmit method that it creates. The problem is that my running aspx page cannot find the igtbl_submit method and errors with

“Microsoft JScript runtime error: The value of the property 'igtbl_submit' is null or undefined, not a Function object”

Does anyone know what this method does, where it should be located etc? My final goal is to upgrade the infragistics controls we use to the latest offerings, but I need to get the existing solution upgraded (as a kind of Stage 1 phase).
