Bind to column object, not column name.

[Scott]

What is the correct way use a "DataColumn" object to tell the RadGridView which column to bind to? I can get it to bind using the "ColumnName" property on the column, but I would rather bind on the DataColumn object itself.

Here is a test program to demonstrate the problem

<Window x:Class="RadGridViewTest.MainWindow"
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                xmlns:radGridViewTest="clr-namespace:RadGridViewTest"
                Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <radGridViewTest:ContextData x:Key="ContextData"/>
    </Window.Resources>

    <Grid DataContext="{StaticResource ContextData}">
        <telerik:RadGridView ItemsSource="{Binding Path=ExampleTable}"
                             AutoGenerateColumns="True"
                             ShowGroupPanel="False">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding ExampleColumn}" Header="Via property"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Example}" Header="Via Column Name"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</Window>

​

using System.Data;
using System.Windows;

namespace RadGridViewTest
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }

    public class ContextData
    {
        public ContextData()
        {
            ExampleTable = new StrongNamedDataTable();

            var row = ExampleTable.NewRow();
            row[ExampleTable.ExampleColumn] = "Test Data";
            ExampleTable.Rows.Add(row);
        }

        public StrongNamedDataTable ExampleTable { get; set; }
    }

    public class StrongNamedDataTable : DataTable
    {
        public StrongNamedDataTable()
        {
            ExampleColumn = this.Columns.Add("Example");
        }

        public DataColumn ExampleColumn { get; private set; }
    }
}

The column that I set via the property did not work, but the one referencing the column name and the auto generated column both worked. What is the correct way to reference a column using the property?

Hi Scott,

Generally, if you want to bind GridViewDataColumn to a specific column of your DataTable, you need to use the name of DataTable's column. Please note that you will get the same behaviour with MS DataGrid.
