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");
Hi,
You can access the xamGrid with the following code:
XamGrid grid = col.ColumnLayout.Grid;
Note: i'm assuming your CheckboxColumn is bound. If so, instead of looping through the rows, i'd recommend accessing the ItemSource, and walking through the collection and accessing your data directly. It should produce faster results.

Dahhh. You are right, my bad. Now it's firing both events.
Last issue following the same sample.
Once in :
protected override void ExecuteCommand(Column col)
{
// How can I access grid's rows to change all/none checkboxes on my template column if all I have is "col"?
// I cannot access the grid directly because this is another class.
// I checked Column properties but didn't see any one that could give me the grid, is that possible?
}
The name of the property you want to set is Commands (plural) not Command.
<ig:Commanding.Commands>
<local:MyCommandSourceUnchecked EventName=""Unchecked""></local:MyCommandSourceUnchecked>
<local:MyCommandSourceChecked EventName=""Checked""></local:MyCommandSourceChecked> </ig:Commanding.Commands>
I think I have everything just like you posted it.
I have a zip proj with the sample. I'm using 2 different commands but it is the same if I do it just like you have it.
Here goes the sample.
Hi Rodolfo,
I just tested this out, and its still working.
Are you doing exactly what i was doing in the example code? And setting the EventName to be 2 separate events?
Or are you using a button, and hooking into the click event for both commands?
Do you have a sample that you can send that shows the issue?
