Create a Class that inherits ITemplate and add controls the container ; you want to add.
Assign the object of that class to ASPxGridView's 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 event handler in the custom template except using on the RowCommand event.
