I have 2 classes generated by Entity Framework as follows. My requirement is depending on the SystemEntity_ID in the JobEntity class, I want to bind the IsChecked property of the checkbox in the listview. The problem is right now all the checkboxes are being checked...Please help..
public partial class JobEntity
{
public int JobEntity_ID { get; set; }
public int Job_ID { get; set; }
public Nullable<int> SystemEntity_ID { get; set; }
public string EntityMigrationStatus { get; set; }
}
public partial class sp_SelectEntities_Result
{
public Nullable<int> Project_ID { get; set; }
public Nullable<int> Site_ID { get; set; }
public int SystemEntity_ID { get; set; }
public string EntityDesc { get; set; }
}
Below is my Viewmodel class:
public class EntityViewModel
{
private List<sp_SelectEntities_Result> entitylist;
private ObservableCollection<sp_SelectEntities_Result> _ObCollection;
private EntityDbContext db;
List<int> Selectedvalues = new List<int>();
public EntityViewModel()
{
db = new EntityDbContext();
entitylist = db.sp_SelectEntities().ToList();
convert();
}
public void convert()
{
_ObCollection = new ObservableCollection<sp_SelectEntities_Result>(entitylist);
}
public ObservableCollection<sp_SelectEntities_Result> obcollection
{
get { return _ObCollection; }
set { _ObCollection = value; }
}
}
My view i.e. MainWindow.
<ListView x:Name="lstentities" ItemsSource="{Binding obcollection}" Height="250" VerticalAlignment="Top">
<ListView.View>
<GridView>
<GridViewColumn Header="Selected">
<GridViewColumn.CellTemplate>
<DataTemplate>
<CheckBox x:Name="chk" IsChecked="{Binding SystemEntity_ID}" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn DisplayMemberBinding="{Binding EntityDesc}" Header="Entity" />
</GridView>
</ListView.View>
</ListView>
and in the mainwindow.cs
public MainWindow()
{
InitializeComponent();
EntityViewModel ev = new EntityViewModel();
this.DataContext = ev;
}
The problem is that you are trying to bind nullable int to a boolean property. If you want this any way. You need a converter or Data Trigger.
Since I don't know what value will make the checkbox checked and what value will make the checkbox unchecked, i can write any code for your.
Hope this helps.
Kind Regards
