c# - WPF Datagrid binding and column display

Question

I have datatable as Item source for DataGrid, this datatable has lots of columns. Is it possible to display few columns instead all of them without creating a new table?

Answer 1

Yes, it is. Just mark AutoGenerateColumns=False and manually define your columns. You can use normal text-bound columns, checkbox columns, custom XAML template columns and more, as you can see in the documentation.

<DataGrid ItemsSource="{Binding DataSource}" AutoGenerateColumns="False" >
    <DataGrid.Columns>
    <DataGridTextColumn Header="Simple Value"
                      Binding="{Binding SimpleValue}" Width="*" />
     <DataGridTemplateColumn Width="*" Header="Complex Value">
        <DataGridTemplateColumn.CellTemplate>
          <DataTemplate>
            <StackPanel>
               <TextBox Text="{Binding ComplexValue}"/>
               <TextBox Text="{Binding ComplexValue2}"/>
            </StackPanel>
          </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>
      </DataGridTemplateColumn>
    </DataGrid.Columns>
  </DataGrid>
