[Solved] Command item Template

[Judith]

In your examples you use a special SessionDataSource and asp:AccessDataSource on the asp page. At our installation we do not place datasources on the asp page - they are usually implemented as typed/non-typed datasets stored in a session variable that are bound to the grid in the grid_NeedDataSource  event: grid.DataSource = DataTable; 
What do I need to do for Command item Template model to work  as it does in your example?

Hello Judith,

It is not obligatory to use datasource control in this case. AdvancedDataBinding with NeedDataSource should be working for you in the mentioned scenario. Could you please provide more details about the problem you face?

Hi Judith,

Can you verify that the grid/page ViewState is there? Generally you can find the same example with our old classic grid ASP.NET 1.x style (NeedDataSource binding) and it is still working:
