Binding CellValuePresenter.IsSelected with Styles codebehind
posted

I'm currently trying to rewrite one of my applications with the xamDataGrid.
Before that i used the WPFToolkit datagrid.

I need to bind with Styles in the code behind.

This does work:

                    CellStyle.Setters.Add(new Setter()
                    {
                        Property = CellValuePresenter.TagProperty,
                        Value = new Binding("DataItem.[2008].Flag")
                    }
                    );

This doesn't work:

                    CellStyle.Setters.Add(new Setter()
                    {
                        Property = CellValuePresenter.IsSelectedProperty,
                        Value = new Binding("DataItem.[2008].IsSelected")
                    }
                    );

 

It is basically the same operation, but for some reason the IsSelectedProperty doesn't execute the binding.

With  WPFToolkit grid this still works and though i know that there are better ways to accomplish this task with the xamDataGrid, i would have to rewrite much of my coding.


Does anybody know what i can do, or what is different with the IsSelectedProperty??


Thx
Johannes

    If someone should ever need this, here is a more solid version of the workaroung:

     

          #region mainGrid_SelectedItemsChanging

          //workaround!!!
          private void mainGrid_SelectedItemsChanging(object sender, Infragistics.Windows.DataPresenter.Events.SelectedItemsChangingEventArgs e)
          {
              //Unselect all previous selected DataPoints
              ManageDataPointSelection(mainGrid, mainGrid.SelectedItems, false);

              //Select all new Datapoints
              ManageDataPointSelection(mainGrid, e.NewSelection, true);
          }


          #endregion //mainGrid_SelectedItemsChanging


          #region ManageDataPointSelection

          /// <summary>
          /// Manages the selection of the DataPoints.
          /// </summary>
          /// <param name="grid">the grid</param>
          /// <param name="selectedItems">The collection of selectedItems of the grid</param>
          /// <param name="select">Determines wheter to select (true) or unselect (false) the dataPoints</param>
          public void ManageDataPointSelection(XamDataGrid grid, DataPresenterBase.SelectedItemHolder selectedItems, bool select)
          {
              Model.Indicator indicator = null;
              Model.DataPoint dataPoint = null;

              //SelectedCells
              if (selectedItems.Cells.Count > 0)
              {
                  foreach (Cell cell in selectedItems.Cells)
                  {
                      indicator = (Model.Indicator)cell.Record.DataItem;
                      dataPoint = (Model.DataPoint)indicator[cell.Field.Label.ToString()];

                      if (dataPoint != null)
                          dataPoint.IsSelected = select;
                  }
              }

              //SelectedRecords
              else if (selectedItems.Records.Count > 0)
              {
                  foreach (DataRecord record in selectedItems.Records)
                  {
                      indicator = (Model.Indicator)record.DataItem;
                      if (!select)
                          indicator.clearSelectedDataPoints();
                      else
                      {
                          indicator.SelectDataPoints();
                      }
                  }
              }

              //SelectedFields
              else if (selectedItems.Fields.Count > 0)
              {
                  foreach (DataRecord record in grid.Records)
                  {
                      foreach (Field field in selectedItems.Fields)
                      {
                          indicator = (Model.Indicator)record.DataItem;
                          dataPoint = (Model.DataPoint)indicator[field.Label.ToString()];

                          if (dataPoint != null)
                              dataPoint.IsSelected = select;
                      }
                  }
              }
          }

          #endregion //ManageDataPointSelection
