Static Resource Value from Binding Question

Question

I have a UserControl that has a DataGrid on it.  It is bound to a Public Property in my ViewModel.

One of the columns on the grid needs to be bound to a global boolean in the ViewModel.  That is to say, a ViewModel Property, not a property in the Object the Grid is Bound too.

Doesn't look like you can do:

    <UserControl.Resources>
        <sys:Boolean x:Key="ManagedSignedFormsAuthorization">{Binding MyViewModelBoolean}</sys:Boolean>
    </UserControl.Resources>

So I want to bind a column in my grid to a StaticResource and the StaticResource needs to get its value from the ViewModel.

Hi maikeu-sama,

Please follow below code

In ViewModel add a public property of bool type

public bool  isFalse {get;set;}

In MainPage.xaml

    <UserControl.Resources>
        <local:ViewModel x:Key="ViewModel" /> //here local namespace is refered to current project.
    </UserControl.Resources>

<DataGrid>

...

                <sdk:DataGridTemplateColumn CanUserReorder="True" CanUserResize="True" CanUserSort="True" Width="Auto" >
                    <sdk:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox IsChecked="{Binding isFalse, Source={StaticResource ViewModel}}" />
                        </DataTemplate>
                    </sdk:DataGridTemplateColumn.CellTemplate>
                </sdk:DataGridTemplateColumn>

...

</DataGrid>

 

Best Regards,
