Hi! I got the following situatino:
I derivated XamGrid to make my custom grid and I create dinamically some column. One of then is a CheckBoxColumn that binds into a property named "Selecionado".
What I need is to create in the header of this column a checkbox that check/uncheck all checkboxes in this column.
Pretty simple, but I create this template dinamically using an StyleWrapper I build. In my style dictionary i declared a DataTemplate that contais a checkbox, as shown above.
<DataTemplate x:Name="ucGridPermissaoColSelecionadoHeaderTemplate" >
<CheckBox x:Name="ckbTodos" HorizontalAlignment="Center" />
</DataTemplate>
When my grid is instatiated, I do the following, where StyleWrapper.GetItem<DataTemplate> return the DataTemplate i`ve shown before. How do I do that???
CheckBoxColumn colSelecionado = new CheckBoxColumn();
colSelecionado.HeaderTemplate =
StyleWrapper.GetItem<DataTemplate>("ucGridPermissaoColSelecionadoHeaderTemplate");
I am not sure what the question is here.
Does your GetItem return a valid DataTemplate? Are you not getting that value? Could you clarify what you are asking?
The DataTemplate as written isn't going to do much, just be Checkbox. You would need to attach an event handler (or two) to it to function.
The question is: How do I add an event Handler to Checked in this Checkbox? This template is in my resource dictionary and my grid is a class that derivates from XamGrid. The GetItem method returns a valid DataTemplate. All I need is know how do add this event handler. Thanks!
