Thanks for your reply.

After I set  the ‘CellClickAction’ property to “SelectCell”, I need select the cell by the first click, and change the state of checkbox by second click. Is there any solution to do the select cell and change the state of checkbox by the once click?

Hello,

I have been looking into your question and I can suggest setting ‘CellClickAction’ property to “EnterEditModeIfAllowed”.

If you need any further assistance on this matter, do not hesitate to ask.

Ah, in that case, user cant select multi-cells by drag mouse.

Hello,

I have been looking into your last post and this is the default behavior of the XamDataGrid when the ‘CellClickAction’ property is set to “EnterEditModeIfAllowed”. I can suggest you allow entering in edit mode only for the column with the XamCheckEditors by defining a field layout like e.g. :

            <igDP:XamDataGrid.FieldSettings>

                <igDP:FieldSettings CellClickAction="SelectCell"></igDP:FieldSettings>

            </igDP:XamDataGrid.FieldSettings>

            <igDP:XamDataGrid.FieldLayouts>

                <igDP:FieldLayout Key="Cars">

                    <igDP:FieldLayout.Fields>

                        <igDP:Field Name="Make" Label="Make" />

                        <igDP:Field Name="Model" Label="Model" />

                        <igDP:Field Name="BasePrice" Label="BasePrice" />

                        <igDP:Field Name="Mileage" Label="Mileage" />

                        <igDP:Field Name="Flag"   Label="Flag">

                            <igDP:Field.Settings>

                                <igDP:FieldSettings CellClickAction="EnterEditModeIfAllowed"/>

                            </igDP:Field.Settings>

                        </igDP:Field>

                    </igDP:FieldLayout.Fields>

                </igDP:FieldLayout>

            </igDP:XamDataGrid.FieldLayouts>

and handling the ‘PreviewMouseLeftButtonUp’ event in order to start the edit mode for other cells on mouse click when you do not want to select multiple cells by mouse dragging :

      private void xamDataGrid1_PreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)

        {

            if (xamDataGrid1.SelectedItems.Cells.Count == 1)

            {

                xamDataGrid1.ExecuteCommand(DataPresenterCommands.StartEditMode);

            }

        }

If you have any other questions on this matter, feel free to ask.

Thank you a lot, I have implemented that by another way, I set all the fields' ‘CellClickAction’ property to “SelectCell”, and implemented the Style of XamCheckEditor by this way:

<Style TargetType="{x:Type igEditors:XamCheckEditor}">                                    

       <Setter Property="HorizontalAlignment" Value="Center"/>                                    

       <Setter Property="VerticalAlignment" Value="Center" />                                    

       <EventSetter Event="MouseLeftButtonDown" Handler="ChangeCheckboxStatus"/>                                

</Style>

 private void ChangeCheckboxStatus(object sender, MouseButtonEventArgs e)        

 {            

           var xamCheckEditor = sender as XamCheckEditor;            

           if (xamCheckEditor != null)            

           {                

                    xamCheckEditor.StartEditMode();                

                    xamCheckEditor.IsChecked = !xamCheckEditor.IsChecked;                

                    xamCheckEditor.EndEditMode(true, true);            

            }        

}
