Clickhandler to delete an tablerow - xamarin.android

Question

I'm building an app were i add tablerows to a view programmatically. I add a deletebutton to every row that is an ImageButton. Now i have a few questions.
Can i use an ImageButton for this?
How do i get the tablerow id
where the deletebutton was clicked?
How can i convert the eventargs
from a clickhandler into MenuItemOnMenuItemClickEventArgs or vice
versa?
How should my clickhandler look like?
Here is my sourcecode:
public class CalculatorSide2 : Activity
{
private Button stepButton;
private IntentHelper intentHelper = new IntentHelper();
private string age;
private string estLife;
private string estPens;
private string[] pensions;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
intentHelper.IntentSide2(Intent, out age, out estLife,out estPens);
SetContentView(Resource.Layout.calculatorside2);
TableLayout tl_layout = FindViewById<TableLayout>(Resource.Id.tableLayout1);
ImageView plusButton = FindViewById<ImageView>(Resource.Id.plusButton);
stepButton = FindViewById<Button>(Resource.Id.cside2stepButton);
plusButton.Click += (sender, e) =>
{
PopupMenu popupMenu = new PopupMenu(this, plusButton);
popupMenu.Inflate(Resource.Menu.popupmenu);
fillPopupMenu(popupMenu);
popupMenu.Show();
popupMenu.MenuItemClick += (s1, arg) =>
{
string info = arg.Item.TitleFormatted.ToString();
string id = arg.Item.ItemId.ToString();
var inputDialog = new AlertDialog.Builder(this);
EditText userInput = new EditText(this);
userInput.InputType = (Android.Text.InputTypes.NumberFlagDecimal | Android.Text.InputTypes.ClassNumber);
inputDialog.SetTitle(info);
inputDialog.SetView(userInput);
inputDialog.SetPositiveButton("Ok", (ss, ee) =>
{
TextView rowInfo = new TextView(this);
rowInfo.SetLines(2);
rowInfo.TextSize = 20;
rowInfo.SetTextColor(Android.Graphics.Color.Black);
rowInfo.Text = info + ": \n" + userInput.Text + "€";
ImageButton delete = new ImageButton(this);
delete.SetBackgroundDrawable(Resources.GetDrawable(Resource.Drawable.delete_icon));
TableRow row = new TableRow(this);
row.LayoutParameters = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.MatchParent);
row.SetBackgroundColor(Android.Graphics.Color.Rgb(255, 153, 0));
row.SetPadding(0, 0, 0, 30);
row.AddView(rowInfo);
row.AddView(delete);
tl_layout.AddView(row);
});
inputDialog.SetNegativeButton("Cancel", (se, es) => { });
inputDialog.Show();
};
};
stepButton.Click += (object sender, EventArgs e) =>
{
var step = new Intent(this, typeof(CalculatorSide3));
step.PutExtra("Age", age);
step.PutExtra("EstPens", estPens);
step.PutExtra("EstLife", estLife);
step.PutStringArrayListExtra("Pensions", pensions);
StartActivity(step);
};
}
private void fillPopupMenu(PopupMenu menu)
{
int groupId = 0;
int i = 0;
int menuItemId = Android.Views.Menu.First;
int menuItemOrder = Android.Views.Menu.None;
foreach (var item in Enum.GetNames(typeof(PopupMenuItems)))
{
string itemString = item.ToString();
menu.Menu.Add(groupId, menuItemId + i, menuItemOrder + i, itemString.Replace("_", " "));
i++;
}
}
}
I hope someone understands what i mean, bc english is not my native language.
