Is there a reason why you want to use a template column? If you use a regular bound column the grid will take care of all the data binding.


>I have an mmDataGrid with a template column. I edited the template column and dropped in an mmTextBox control. I ran the web app at that point and the page came up just fine.
>
>I went back and set the binding properties on the textbox so that it is bound to a column of a business object's dataset and am now getting the error page below. My question, before I post specific property values and code, is does the framework currently support bound mm web controls inside an mmDataGrid? I looked in the MM 1.1 Dev Guide for an example of this, but did not find one.
