WPF XamDataGrid doesn't update until leaving current cell

Question

I have SEVERAL XamDataGrids in my application, and I want all of them to enable the respective Save buttons as soon as the user changes a checkbox in them. This currently doesn't happen until I leave the cell or press enter etc, because the cell is still in edit mode. I know how to fix this using a post I found in code-behind:

private void XamDataGrid_CellChanged(object sender, Infragistics.Windows.DataPresenter.Events.CellChangedEventArgs e)
        {
            e.Cell.Record.SetCellValue(e.Cell.Field, e.Editor.Value, true);
        }

But how can i handle this for ALL my grid across the app, without putting this in code-behind for every grid? I am using MVVM and would prefer to not have any code behind, if possible. If I have to, i will, but i defintitely don't want it in the code behind in 17 different files with grids. Maybe a behavior?

Answer 1

You need to set the DataItemUpdateTrigger to OnCellValueChange.

Default value for all fields in a XamDataGrid

<igDP:XamDataGrid.FieldSettings>
    <igDP:FieldSettings 
        DataItemUpdateTrigger="OnCellValueChange" />
</igDP:XamDataGrid.FieldSettings>

• I believe this could easily be applied as a style for all XamDataGrids.

For an individual Field

<igDP:Field Label="" Name="IsSelected" >
    <igDP:Field.Settings>
        <igDP:FieldSettings DataItemUpdateTrigger="OnCellValueChange" />
    </igDP:Field.Settings>
</igDP:Field>

DataItemUpdateTrigger property is available in FieldSettings class in NetAdvantage 2013 v. 2 or later.
