Rowcommand do not fire after clicking button

Question

I have already find out the solution, i just want to post it so this may be useful for some people

This is the button that use command

Answer 1

The Problem is that on Page_Load I use Databind() command on the gridview I'm using rowcommand, it seems that after DataBind(), rowcommand is cancelled.

    protected void Page_Load(object sender, EventArgs e)
    {
            gdvxUsers.DataSource = GetAllUserAndRole();
            gdvxUsers.DataBind();            
    }

So I fix this problem by binding data only on first load.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            gdvxUsers.DataSource = GetAllUserAndRole();
            gdvxUsers.DataBind();
        }
    }
