Datagridtextcolumn bind to datatable

Question

I am having some problems when I have a datatable and I want to bind each datagridtextcolumn in the datagrid to each column in the datatable.

my code is as below

public class Packet
{
    public Header header { get; set; }
    public Frame frame { get; set; }
    public Tail tail { get; set; }
    public String id { get; set; }

    public Packet(String id,Header header, Frame frame, Tail tail)
    {
        this.id = id;
        this.header = header;
        this.frame = frame;
        this.tail = tail;
    }

}

Hence on my xaml side

<Grid >
    <DataGrid AutoGenerateColumns="False" ItemsSource="{Binding Path=.}" Name="dgrid" SelectionChanged="dgrid_SelectionChanged">
        <DataGrid.Columns>
            <DataGridTextColumn Header="ID" Binding="{Binding Path=id}"/>
        </DataGrid.Columns>

    </DataGrid>
</Grid>

And on my code side, ds is a dataset which has one datatable. Each row is a packet 4 columns corresponding to header frame tail and id. I am trying to get the id to bind correctly first. But the id number cannot display on the datagrid.

dgrid.DataContext = ds.Tables[0];

It actually displays the correct data if i do not use the datagridtextcolumn on the xaml side. but what i wanted is to do the binding on the xaml side to the datatable.

Answer 1

Try this

 <Grid >
        <DataGrid AutoGenerateColumns="False" Name="dgrid" SelectionChanged="dgrid_SelectionChanged">
            <DataGrid.Columns>
                <DataGridTextColumn Header="ID" Binding="{Binding Path=id}"/>
            </DataGrid.Columns>
        </DataGrid>
    </Grid>

    dgrid.ItemsSource = ds.Tables[0].AsDataView();

If you have a model class like Packet in your case, then I would suggest to use observable collection instead of DataTable to hold the list of Packets . DataTable 's item is of type DataRowView .

I am not even sure how is your DataTable holding a Packet instance?

If your ds.Tables[0].Rows[0] of Packet type or ds.Tables[0].Rows[0] [0] is of Packet type?

If so that would cause lot of trouble for binding.
