To fix the issue you can do You should use DataGridTemplateColumn instead. Here there is code sample.

code :

<DataGrid.Columns>
    <DataGridTemplateColumn Header="Image" CellTemplate="{StaticResource ImageCellTemplate}"/>
</DataGrid.Columns>

<DataGrid.Resources>
    <DataTemplate x:Key="ImageCellTemplate">
        <Grid>
            <Image Source="{Binding Path=Image}"/>
        </Grid>
    </DataTemplate>
<DataGrid.Resources>

DataGridTextColumn - How to bind IsReadonly?

hope this fix your issue what you can do is to create an attached property to handle the change of the IsReadOnly property in the DataGridTextColumn.

code :

public class Class1
{
    public static void SetIsReadOnly(DependencyObject obj, bool isReadOnly)
    {
        obj.SetValue(IsReadOnlyProperty, isReadOnly);
    }

    public static bool GetIsReadOnly(DependencyObject obj)
    {
        return (bool)obj.GetValue(IsReadOnlyProperty);
    }

    // Using a DependencyProperty as the backing store for MyProperty.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty IsReadOnlyProperty =
        DependencyProperty.RegisterAttached("IsReadOnly", typeof(bool), typeof(Class1), new PropertyMetadata(false, Callback));

    private static void Callback(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        ((DataGridTextColumn)d).IsReadOnly = (bool)e.NewValue;
    }
}

<sdk:DataGridTextColumn local:Class1.IsReadOnly="True" Binding="{Binding Property1}" Header="Property1"/>

        <sdk:DataGridTextColumn Binding="{Binding Name}"
                                local:Class1.IsReadOnly="{Binding DataSource.IsInEditMode, Source={StaticResource DataContextProxy}, Converter={StaticResource xxxConverter}}"
                                Header="ReadOnly Header" />

Bind DataGridTextColumn with calculation in MVVM

like below fixes the issue As I've already suggested, you can create a view model class for the collection item and populate it as it should be.

code :

public class VerificationViewModel
{
    public int AuthorizationVerificationId { get; set; }

    public double Amount { get; set; }
}

loadOp.Completed += (sender, e) =>
{
   IEnumerable<AuthorizationVerification> op = 
           ((LoadOperation<AuthorizationVerification>)sender).Entities;

   var models = op.GroupBy(item => item.AuthorizationVerificationId)
                  .Select(g => new VerificationViewModel
                                { 
                                    AuthorizationVerificationId = g.Key, 
                                    Amount = g.Sum(gi => gi.Amount) 
                                })
                  .ToList();

   PagedCollectionView view = new PagedCollectionView(models);
   // Everything else is the same
}

//Also change the type of the property which is bound to SelectedItem
public VerificationViewModel SelectedCreditNote { get; set; }

<sdk:DataGrid.Columns>
  <sdk:DataGridTextColumn Header="Credit No" 
     Binding="{Binding Path=AuthorizationVerificationId}" Width="200"/>

  <sdk:DataGridTextColumn Header="Amount" 
     Binding="{Binding Path=Amount}" MinWidth="100" Width="*"/>

</sdk:DataGrid.Columns>

How to bind WPF combobox selected item with a Value Converter to a DataGridTextColumn? Both DataGridTextColumn and combo

By : Madhu

I wish did fix the issue. So what's stopping you from using IValueConverter. Declare under Resource section and use it like this:

code :

<DataGrid.Resources>
   <namespace:MyConverter x:Key="MyConverter"/>
</DataGrid.Resources>
.....
<DataGridTextColumn Header="Right"
                    Binding="{Binding SelectedColumn, Mode=OneWay, 
                                      UpdateSourceTrigger=PropertyChanged,
                                      Converter={StaticResource MyConverter}}"/>

Bind DataGridTextColumn to method WPF

By : Balaianu Andrei

Date : March 29 2020, 07:55 AM

may help you . Is it possible to bind a DataGridTextColumn to a method in my xaml.cs? , You need to use IMultiValueConverter as GertHermans mentioned.

code :

 <DataGridTextColumn  Width="70" Header="Costo">
                <DataGridTextColumn.Binding>
                    <MultiBinding Converter="{StaticResource ConcatConverter}">
                        <Binding Path="Costo" />
                        <Binding Path="SOSMoneda.Descripcion" />
                    </MultiBinding>
                </DataGridTextColumn.Binding>
            </DataGridTextColumn>



 public class ConcatConverter : IMultiValueConverter
        {
            public object Convert(object[] values, Type targetType, object parameters, CultureInfo culture)
            {
                return values[0].ToString() + " " + values[1].ToString();
            }



            public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
            {
                throw new NotImplementedException();
            }
        }

Can't bind DataGridTextColumn property from another thread (WPF)

By : Kaushika

Date : March 29 2020, 07:55 AM

will be helpful for those in need I'm updating DataGrid through binding from different thread (Task). , So I solved it by making converter.
I have made new class

code :

public sealed class ColorCodeConverter : IValueConverter
{
   public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
   {
      ...
   }

   public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
   {
      ...
   }
}

<local:ColorCodeConverter x:Key="ColorCodeConverter" />

<DataGridTextColumn Header="" Width="10">
    <DataGridTextColumn.CellStyle>
        <Style TargetType="DataGridCell">
            <Setter Property="Background" Value="{Binding C7, Converter={StaticResource ColorCodeConverter}}" />
        </Style>
    </DataGridTextColumn.CellStyle>
</DataGridTextColumn>
