Filter Child Grid

[Orit]

Hello
I want to filter my child grid
when I watch the DateView dv it is filtered
but in the child grid I still see all the rows and not only the filtered rows
this is my code

 private void OnChildGridLoaded(object sender, RoutedEventArgs e)
        {
            // Pull data from the detail table based on the relation.
            var dataRowView = (DataRowView)((RadGridView)sender).ParentRow.DataContext;
            var ds = dataRowView.DataView.Table.DataSet;
            var childData = dataRowView.CreateChildView(ds.Relations["BudgetRelation"]);
            if (((ComboBoxValues.ComboValues)cmbActivityType.SelectedValue).Id != 0)
            {
                dv = new DataView(childData.ToTable(), "ActivityTypeID=" + ((ComboBoxValues.ComboValues)cmbActivityType.SelectedValue).Id, "", DataViewRowState.CurrentRows);
                ((RadGridView)sender).DataContext = dv;
            }
            else
                ((RadGridView)sender).DataContext = childData;

            ((GridViewComboBoxColumn)((RadGridView)sender).Columns["ActivityTypeName"]).ItemsSource = ComboBoxValues.GetComboValues(dtActivityType);
        }

Thanks

By the way, I'm still waiting for an answer about second child hierarchy.

Hello Orit,

Is there a reason for setting the DataContext of the grid instead of its ItemsSource?

Anyway, we will need the whole project in order to debug it. This code-snippet would not be enough.

Please send it to us and we will take a look at it.

Best wishes,
