hierarchy Issue

[FantasmaWeb]

hello:

    I have a trouble with the Hierarchy in the gridview.  I have my gridview,that filled it on codebehind and everything it´s working fine even the hierarchy .. But when I try to use a HierarchyChildTemplate  I just see the plus Symbol, what that means I got a childrows but when i click on the Symbol nothing happens.
  

 

 

 

<telerik:RadGridView.HierarchyChildTemplate><DataTemplate><telerik:RadGridView x:Name="RadGridViewChildrenMiles" ColumnsWidthMode="Auto"

 

 

 

AutoGenerateColumns="False">
<telerik:RadGridView.Columns><grid:GridViewDataColumnHeader="Descripcion"

 

 

 

DataMemberBinding="{Binding Descripcion}"/></telerik:RadGridView.Columns>

 

 

 

 

</telerik:RadGridView>
</DataTemplate></telerik:RadGridView.HierarchyChildTemplate>


Sorry if my english it´s no so good

Regards

Hi,

 You child grid is not bound - you need to assign ItemsSource.

Kind regards,

I assign  the itemsource in the codebehind and the table definition  just like one of your examples, in fact  the child grid is bound before set the HierarchyChildTemplate but when i put the HIerarchyChildTemplate just i can't see the child grid

 

Telerik.Windows.Controls.GridViewTableDefinition detailsTableDefinition = new Telerik.Windows.Controls.GridViewTableDefinition();

detailsTableDefinition.Relation = new Telerik.Windows.Data.PropertyRelation("Details");

this.myRadGridViewMiles.TableDefinition.ChildTableDefinitions.Add(detailsTableDefinition);

Hi 

 Since you have defined template this automatic binding will not work. To achieve your goal you can set ItemsSource="{Binding Details}" in XAML for the child grid directly and insert an empty table definition with no relations just to tell the grid that you have hierarchy. You can check our demo for more info.

Im still have the same problem.... this is my Grid definition

<telerik:RadGridView Margin="0,0,0,1"

                  </telerik:GridViewDataColumn.Footer>

 </telerik:RadGridView.Columns>

          <telerik:RadGridView.HierarchyChildTemplate>
              <DataTemplate>
                  <telerik:RadGridView x:Name="RadGridView1"
                                       CanUserFreezeColumns="False"
                                       AutoGenerateColumns="False"
                                       ItemsSource="{Binding Details}"
                                       ShowGroupPanel="False"
                                       IsReadOnly="True"      >
                      <telerik:GridViewDataColumn DataMemberBinding="{Binding Sem52}" Header="Product ID" />
                  </telerik:RadGridView>
              </DataTemplate>
          </telerik:RadGridView.HierarchyChildTemplate>
      </telerik:RadGridView>

and this is the model what I Use to bind the Grid

public class Details : INotifyPropertyChanged
      {
          private double sem52 = 0;
          public double Sem52
          {
              get { return sem52; }
              set {
                  if (value != this.sem52)
                  {
                      sem52 = value;
                      this.OnPropertyChanged("Sem52");
                  }
              }
          }
public Details()
          {

          }


          #region INotifyPropertyChanged Members
          public event PropertyChangedEventHandler PropertyChanged;
          #endregion
          protected virtual void OnPropertyChanged(PropertyChangedEventArgs args)
          {
              PropertyChangedEventHandler handler = this.PropertyChanged;
              if (handler != null)
              {
                  handler(this, args);
              }
          }
          private void OnPropertyChanged(string propertyName)
          {
              this.OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
          }
      }

and the Class that use the Collection for the child items

   public class TabAnual : INotifyPropertyChanged

        {

            public event PropertyChangedEventHandler PropertyChanged;

  

            private ObservableCollection<Details> details;

  

            public TabAnual()

                    }

  

                    return this.details;

                }

            }

  

  

  

            private double totals = 0;

            public double Totals

            {

                get { return totals; }

                set {

                    if (value != this.totals)

                    {

                        totals = value;

                        this.OnPropertyChanged("Totals");

                    }

                }

            }

                        totals_totals = value;

                        this.OnPropertyChanged("Totals_totals");

Hi FantasmaWeb,

The syntax of the child table is not correct - column declarations should be inside Columns.

It works like a charm. Thanks for everything .. I didn't see it before
