Programmatically adding template field in ASP.NET GridView problem

Asked by Dixon8402 in Programming for ASP.NET, C# Programming Language, Visual Studio

Tags:

I am trying to programmatically add a template field to an ASP.NET GridView control using C# code behind. I can successfully add the template field with not problem, the problem I am having is capturing events of the template.
For instance, Before adding the columns dynamically I had a column that was a template field that contained a check box.  When clicked the checkbox called some javascript that highlighted the selected row. Is their a way of still being able to do this using the dynamic method.? Any help would be greatly appreciated.
