Access values of controls in grid... Help please.

Hello,

I have a grid that is completly dynamic. The user can add as many rows as they want to this grid. What I need to do is somehow get the values of each control in each row so that I can create either a linq query or xml to send down to the server.

Here is the code for adding a row when a button is clicked:

ButtonClick:

1            private void AddNewFilter_Click(object sender, RoutedEventArgs e)
2            {
3                Button addButton = sender as Button;
4                int row = (int)addButton.GetValue(Grid.RowProperty);
5                FilterGrid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(30) });
6                AddRow(row);
7                addButton.SetValue(Grid.RowProperty, row + 1);
8            }

 AddRow Method:

1            public void AddRow(int row)
2            {
3                andOrComboBox = new ComboBox() 
4                { 
5                    ItemsSource = new List() { AndOrEnum.SelectOne, AndOrEnum.And, AndOrEnum.Or}, 
6                    SelectedIndex = 0
7                };
8                andOrComboBox.SetValue(Grid.RowProperty, row);
9                andOrComboBox.SetValue(Grid.ColumnProperty, 0);
10   
11   
12               propertyComboBox = new ComboBox();
13               List properties = new List();
14               properties.Add(new PropertyValue() { Name = "SelectOne", TypeOfProperty = null });
15               foreach (PropertyInfo info in propertyInfo)
16               {
17                   
18                   object[] attributes = info.GetCustomAttributes(typeof(FilterAttribute),true);
19                   if (attributes.Length > 0)
20                   {
21                       FilterAttribute f = (FilterAttribute)attributes[0];
22                       if (f.IsFilterable)
23                       {
24                           if (f.FilterName != null)
25                           {
26                               properties.Add(new PropertyValue() { Name = f.FilterName, TypeOfProperty = info.PropertyType});
27                           }
28                           else
29                           {
30                               properties.Add(new PropertyValue() { Name = info.Name, TypeOfProperty = info.PropertyType });
31                           }
32                       }
33                   }
34               }           
35               propertyComboBox.ItemsSource = properties;
36               propertyComboBox.ItemTemplate = propertyValueTemplate;
37               propertyComboBox.SelectedIndex = 0;
38               propertyComboBox.SetValue(Grid.RowProperty, row);
39               propertyComboBox.SetValue(Grid.ColumnProperty, 1);
40               propertyComboBox.SelectionChanged += new SelectionChangedEventHandler(propertyComboBox_SelectionChanged);
41   
42               operatorComboBox = new ComboBox() 
43               { 
44                   ItemsSource = new List() 
45                   { 
46                       OperatorsEnum.SelectOne,
47                       OperatorsEnum.EqualTo,
48                       OperatorsEnum.GreaterThan,
49                       OperatorsEnum.GreaterThanOrEqualTo,
50                       OperatorsEnum.LessThan,
51                       OperatorsEnum.LessThanOrEqualTo,
52                       OperatorsEnum.NotEqualTo
53                    } , 
54                    SelectedIndex  = 0                
55               };
56               operatorComboBox.SetValue(Grid.RowProperty, row);
57               operatorComboBox.SetValue(Grid.ColumnProperty, 2);
58   
59               Button deleteButton = new Button() {Content = "Delete" };
60               deleteButton.Click += new RoutedEventHandler(deleteButton_Click);
61               deleteButton.SetValue(Grid.RowProperty, row);
62               deleteButton.SetValue(Grid.ColumnProperty, 4);
63   
64               FilterGrid.Children.Add(propertyComboBox);
65               FilterGrid.Children.Add(andOrComboBox);
66               FilterGrid.Children.Add(operatorComboBox);
67               FilterGrid.Children.Add(deleteButton);
68   
69           }
70   

Like I said I need to figure out a way to access the controls for each row. This will be used so users can create whatever type of filter they want for specific datagrids. So each row is a filter that can be AND'd or OR'd to each other which is why I need to do it for each row. Oh also the first row in the grid is defined in XAML because it is used as a HeaderRow since Grids don't have HeaderRows, so the first row needs to be ignored. Any help is greatly appreciated.
