Question

Firstly let me clarify (if the title wasn’t clear enough): I’m discussing System.Windows.Controls.DataGrid from the .NET 4.0 Framework, not the toolkit edition.

I have a data grid which i read in from a csv which can change with every load.

I am trying to create a simple search, I have been trying to use;

and others, but there all seem very complicated for a simple task, can anyone help, just to be clear a filtering system is not want i am after, thank you.

Answer 1

For my project i did a search function this way :
i added a ‘FilterResult’ Boolean property to the ViewModel of my data. It is implementing NotifyPropertyChanged.
So i perform the filter on my list of object with simple foreach loop and i set/unset FilterResult
And in the ‘Style’ of the DataGridRow i put a Setter on Visibility depending upon this FilterResult

    <Style TargetType="{x:Type DataGridRow}" x:Key="EventColorRowStyle">
        <Style.Triggers>
            <DataTrigger Binding="{Binding FilterResult}"  Value="False">
                <Setter Property="Visibility" Value="Collapsed"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>

This simpler and much faster than using the Filter of a CollectionView, but still i can point you on what msdn says about it : http://msdn.microsoft.com/en-us/library/ff407126.aspx
