I am trying to upgrade from WebDateTimeEdit to WebDateTimeEditor and I get this error. What is a possible solution?
Hi,
WebDateTimeEditor is AJAX (implementes IScriptControl) control and it is not compatible with UltraWebGrid.
Usage of WebDateTimeEditor would require presence of ScriptManager and all other quite heavy stuff in your application which is not required by UltraWebGrid.
If you have WebDateTimeEditor, then you also have WebDataGrid, because it is located in same dll. I suggest you consider replacing UltraWebGrid by WebDataGrid. In this case DateTime-cell editors will be WebDateTimeEditor and other editors (numeric, etc.) will be from same dll too.
