Full postback triggered by LinkButton inside GridView inside UpdatePanel

Question

I have a GridView inside of a UpdatePanel. In a template field is a button I use for marking items. Functionally, this works fine, but the button always triggers a full page

You need to register each controls for each RowState. 1: Register your controls for RowState = Alternate and Normal) 2: Register your controls for RowState = Edit 3: ...

ASPX:

Code behind :

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow 
        && (e.Row.RowState == DataControlRowState.Normal 
            || e.Row.RowState == DataControlRowState.Alternate))
    {
        LinkButton Btn1 = e.Row.FindControl("Btn1 ") as LinkButton; 
        ScriptManager.GetCurrent(this.Parent.Page).RegisterAsyncPostBackControl(Btn1 );
    }
    if (e.Row.RowType == DataControlRowType.DataRow 
        && e.Row.RowState == DataControlRowState.Edit)
    {
        LinkButton Btn2 = e.Row.FindControl("Btn2 ") as LinkButton;
        ScriptManager.GetCurrent(this.Parent.Page).RegisterAsyncPostBackControl(Btn2 );      
    }
}
