I'm using Grid and trying to make control dynamically in loop.

There are 3 Grids, and after clicking on the Grid3 control, I would like to get the control values of Grid1 and Grid2.

Please see image.

Any help is appreciated. Thanks!

code behind:

Dictionary<string, string[]> myDictionary3 = _Model.getRoomStatusData(_Model.RoomTypesSel, _Model.StartTimeNames);
//Grid 1 x:Name="timelist"
for (int i = 0; i < _Model.StartTimeNames.Length; i  )
{   
    Label time = new Label() { Text = _Model.StartTimeNames[i], WidthRequest = 80 };               
    timelist.Children.Add(time, i, 0);               
}

//Grid 2 x:Name="roomtype"
for (int i = 0; i < roomtypes.Length; i  )
{
    roomtype.RowDefinitions.Add(new RowDefinition());           
    Label room = new Label() { Text = _Model.RoomTypesSel[i].Name, WidthRequest = 80 };      
    roomtype.Children.Add(room, 0, i);
}


List<string[]> roomstatu = new List<string[]>()
{
    new string[] {"1","2","3","4","5","6"}, new string[] {"1","2","3","4","5","6"},new string[] {"1","2","3","4","5","6"},new string[] {"1","2","3","4","5","6"},new string[] {"1","2","3","4","5","6"},new string[] {"1","2","3","4","5","6"},new string[] {"1","2","3","4","5","6"},new string[] {"1","2","3","4","5","6"}
};
//Grid 3 x:Name="status"
int index = 0;
foreach (var item in roomstatu)
{
    status.RowDefinitions.Add(new RowDefinition());
    for (int i = 0; i < item.Length; i  )
    {
        status.ColumnDefinitions.Add(new ColumnDefinition());
        Label statuslabel = new Label() { Text = item[i], WidthRequest = 80};                           
        status.Children.Add(statuslabel, i, index);
    }
    index  ;              
}

CodePudding user response：

At first, you can get the index of the label user tapped in the status grid. And then you can get the label's row position and column position by the index.

I have done a sample and it worked well, you can try the following code:

        int index = 0;
        foreach (var item in roomstatu)
        {
            status.RowDefinitions.Add(new RowDefinition());
            for (int i = 0; i < item.Length; i  )
            {
                status.ColumnDefinitions.Add(new ColumnDefinition());
                Label statuslabel = new Label() { Text = item[i], WidthRequest = 80 };
                status.Children.Add(statuslabel, i, index);
                statuslabel.GestureRecognizers.Add((new TapGestureRecognizer
                {
                    Command = new Command(async (obj) =>
                    {
                        Label temp = obj as Label;
                        Grid gridtemp = temp.Parent as Grid;
                        int position = gridtemp.Children.IndexOf(temp);
                        int columnindex = position % timelist.Children.Count;
                        int rowindex = (position / roomtype.Children.Count)  1;
                        
                        string timevalue = ((Label)timelist.Children[columnindex]).Text;
                        string roomtypealue = ((Label)roomtype.Children[rowindex]).Text;
                        temp.Text = timevalue   " "  roomtypealue;
                    }),
                    CommandParameter = statuslabel,
                }));
            }
            index  ;
        }
