Dynamically add controls to footer row using RowTemplate

Create a Class that inherits ITemplate and add controls the container ; you want to add.

Assign the object of that class to ASPxGridView Templates.FooterRow property as:

ASPxGridView1.Templates.FooterRow = new CustomFooterRowTemplate();

And the code snippet of the template class is below:

public class CustomFooterRowTemplate: ITemplate

        {

            void ITemplate.InstantiateIn(Control container)

            {

                Button button = new Button();

                button.Text = "Test";
                 container.Controls.Add(button);

            }

        }
 
 have an idea from this and you can add more controls and even you can use their 
 their event handler in the custom template except using on the rowcommand event.
