CurrentCellValueChanged on GridDataTemplateColumn

[Leclerc Alexandre]

Hello Syncfusion,

I have a GridDataTemplateColumn like this :

var cTmp = new DataTemplate { VisualTree = txtBlck };
var eTmp = TemplateHelper.GetTemplateForEnum(property, colName);

var colap = new GridTemplateColumn
                                    {
                                        MappingName = colName,
                                        HeaderText = headerText,
                                        CellTemplate = cTmp,
                                        EditTemplate = eTmp,
                                        ColumnSizer = GridLengthUnitType.Auto,
                                        AllowResizing = true
                                    };


public DataTemplate GetTemplateForEnum(Type type, string propertyName)
        {
            var elmtFct = new FrameworkElementFactory(typeof(ComboBox));

            elmtFct.SetBinding(
                ItemsControl.ItemsSourceProperty,
                new Binding(propertyName)
                    {
                        Converter = new ComboBoxEnumConverter(),
                        ConverterParameter = type,
                        Mode = BindingMode.OneTime
                });

            elmtFct.SetBinding(
                Selector.SelectedValueProperty,
                new Binding(propertyName)
                    {
                        Mode = BindingMode.TwoWay,
                        UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged,
                        NotifyOnTargetUpdated = true
                    };
 
            elmtFct.SetValue(FocusManagerHelper.WantsKeyInputProperty, true);
            elmtFct.SetValue(FocusManagerHelper.FocusedElementProperty, true);

            return new DataTemplate { VisualTree = elmtFct };
        };

The thing is I would like to trigger CurrentCellValueChanged on the propertychanged event from biding => SelectedValueProperty of combobox .
But, the CurrentCellValueChanged triggers only when de CurrentCell is changed.

Can you tell me how can I trigger without changing cell please ? I'm stuck.

Many Thanks.

Alexandre Leclerc.

Hi  Leclerc, 

 

Thank you for contacting Syncfusion support. 

 

We have analyzed your query. Could you please share some information about your requirement as like, 

    1. While changing any of the cell value means, the CurrentCellValueChanged event only triggered. Could you please confirm, for what purpose you like to trigger the CurrentCellValueChanged event for the combobox selection change? 

    2.  Could you please share your ComboBoxEnumConverter() code and TemplateHelper class file. 

 

If you shared these details, this would be more helpful for us to update the solution as the earliest. 

 

Regards,

Hello Muthukumar,

I'd like to trigger the CurrentCellValueChanged event to check a checkbox which matches to selected row who is editing.
I join you the classes you need.

Thanks.

Hi Leclerc, 

 

Thanks for the update. 

We have analyzed your query. The CurrentCellValueChanged and CurrentCellValidated event are not supported for GridTemplateColumn. As template column can be loaded with any UIElements. You can use CurrentCellActivated event. Within this event, you can get the currentcell of GridTemplateColumn in grid. Please refer the below code snippet, 

 

C#: 

Void datagrid_CurrentCellActivated(objectsender,CurrentCellActivatedEventArgsargs) 

{ 

// you can do code here 

} 

 

You can use PropertyChanged event instead of CurrentCellValueChanged to get value change notification. Please make use of below code snippet, 

 

this.datagrid.View.PropertyChanged += View_PropertyChanged; 

voidView_PropertyChanged(objectsender, System.ComponentModel.PropertyChangedEventArgse) 

{ 

// you can do code here 

} 

 

Please find the sample in the below location and let us know if this helps you.
