Hello
I've been searching for a strange bug, when using a column template, without defining the itemtemplate (i.e. defining only edititemtemplate), Grid Delete command doesn't work any more, it throws an exception like this:
Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.
took me 4 hours to solve it, hope it helps somebody else.
always define <itemtemplate /> even if it's empty .

Hello Viorel,
Thank you for the observation and the reminder. Indeed, when data source operations are implemented, RadGrid's GridTemplateColumn needs to have an <ItemTemplate> defined, although empty. This is because at some point the RadGrid's lifecycle, the ItemTemplate objects are referenced and they need to be initialized in any case.
Kind regards,

Thank you for specifying that every TemplateColumn requires an <ItemTemplate>. That solved my delete error.
