DataGridCheckBoxColumn updates source and is validated only after focus loss
I have a problem with DataGrid
from WPFToolkit
. My grid has DataGridCheckBoxColumn
. When I change value of some cell in this column, validation and real source updating occures only after a cell has lost focus. So, if I change checkbox value in a cell and leave focus inside it, the property of a binded object wouldn't be changed.
Column's binding property UpdateSourceTrig开发者_StackOverflow中文版ger
is set to PropertyChanged
and Mode
is set to TwoWay
.
How can I make binding update my source object immediatly after a checkbox value has been changed?
I don't know for the toolkit-version but with the .net4 version, the binding works as expected. Check your binding-declaration:
<DataGridCheckBoxColumn Binding="{Binding YourProperty,UpdateSourceTrigger=PropertyChanged}">
If it's a specific problem of the toolkit-version, create a DataGridTemplateColumn
and place a CheckBox in the cell-or edit-template and declare the binding on the CheckBox
-control. This will help.
<dg:DataGridTemplateColumn >
<dg:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<CheckBox IsChecked="{Binding YourProperty,UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</dg:DataGridTemplateColumn.CellTemplate>
</dg:DataGridTemplateColumn>
