How can I set the properties of a control in a Template from the QueryCellInfo event?

[Robert Dondo]

How can I get the a control in the DataTemplate of the current row from within the 

QueryCellInfo event?

I want to set a strike-through on a combo-box which I am using in a template. I have the following (not working) code so far:

   private void grdResultsModelOnQueryCellInfo(object sender, GridQueryCellInfoEventArgs e)

        {

 if (e.Style.CellType == "GridDataBoundTemplate")

                    {                      

                        var cboUsername = (ComboBox) e.Style.CellItemTemplate.FindName("cboUsername", this);

                        if (cboUsername != null){

                        //strike through here

                        }

                    }

Hi Robert,

 

Thanks for the patience.

We have analyzed your query. You can set the properties of a control in a Template from the QueryCellInfo event as follows.

Code snippet [C#]:

        void Model_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)

        {

           CellUIElements  cell=dataGrid.Model.CurrencyManager.CurrentCell.Grid.GetCellUIElements(e.Style.RowIndex, e.Style.ColumnIndex);

           if (cell != null)

           {

               Console.WriteLine(cell.UIElements.Count);

               if (cell.UIElements.Count > 0)

               {

                   GridCell gridcell = cell.UIElements[0] as GridCell;

                   if (gridcell != null)

                   {

                       ContentPresenter myContentPresenter = FindVisualChild<ContentPresenter>(gridcell);

                       DataTemplate myDataTemplate = myContentPresenter.ContentTemplate;

                       var checkval = myDataTemplate.FindName("customersCombo", myContentPresenter);

 

                       if (checkval != null)

                       {

                           ComboBox combo = checkval as ComboBox;

                           if (combo != null)

                           {

                                // set properties for combobox

                                combo.Background = Brushes.LightPink;

                                combo.FontStyle = FontStyles.Italic;

                            

                           }

                       }

                   }

               }

           }

 

 

        }
