[Solved] Dynamic binding

[Yuxiao]

Hi,
   I have some trouble when I am doing dynamic binding.  I can add column now. But I can't edit the value in the column.
Can anyone give me some suggestion? 
 

Below is my code.


namespace RadControlsSilverlightApp1

{

 

    public partial class MainPage : UserControl

    {

        string[] columnheaders = { "Model", "Texture", "Retake" };

        ObservableCollection<MyDataRow> _data = new ObservableCollection<MyDataRow>();

 

        public virtual ObservableCollection<MyDataRow> data

        {

            get

            {

                return _data;

            }

            set

            {

                _data = value;

            }

        }

        public MainPage()

        {

 

 

            InitializeComponent();

          

            for (int i = 0; i < 50; ++i)

            {

                MyDataRow row = new MyDataRow();

                foreach (string str in columnheaders)

                {

                    row[str] = new Decimal(1.0);

                }

                _data.Add(row);

            }

            xyz.ItemsSource = data;

            

        }

 

        private void button1_Click(object sender, RoutedEventArgs e)

        {

             

            Telerik.Windows.Controls.GridViewDataColumn gvc = new Telerik.Windows.Controls.GridViewDataColumn();

            gvc.Header = textBox1.Text;

            gvc.UniqueName = textBox1.Text;

            gvc.DataMemberBinding = new Binding(textBox1.Text);

             

            gvc.FilterMemberPath = textBox1.Text;

            gvc.GroupMemberPath = textBox1.Text;

            gvc.SortMemberPath = textBox1.Text;

             

             

            gvc.IsReadOnly = false;

            //gvc.DataType = typeof(Decimal);

            bool allow = true;

            foreach (Telerik.Windows.Controls.GridViewColumn gv in xyz.Columns)

            {

                if (gv.Header.ToString() == textBox1.Text)

                {

                    allow = false;

                    break;

                }

            }

            if (allow)

            {

                foreach (MyDataRow row in data)

                {

                    row[textBox1.Text] = new decimal(3.0);  

                }

 

                xyz.Columns.Add(gvc);

                xyz.Rebind();               

            }

        }

    }

}

Hello,

You can check our online demos showing editing for dynamic data.

I can see that on a button click you set the DataMemberBinding to be textBox1.Text. This is not a recommended way to work the GridViewDataColumn. Would you please work with the data items rather then relying on the text of a visual element?
