Hyperlink in a datatemplatecolumn has issues with updating CurrentItem of DataGrid

I have a DataGrid with rows and columns. Each row corresponds to an item in my data collection. For one of my columns, I want to have a hyperlink with text of the name of my data item, and when I click on the hyperlink, it will execute a command for THAT hyperlink's item (the row it is on)

Hope that makes sense so far.

My issue: How do I bind the hyperlink's CommandParameter to use the current row's data item? I'm running into an issue where if I have some random cell selected (say row 3 column 2) and I click a hyperlink in row 1 column 1, it will say the current item is the item in row 3 not row 1!!!

This is my xaml code:

<DataGridTemplateColumn Width="80">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <TextBlock>
                <Hyperlink Command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}, Path=DataContext.NavigateToFormCommand}"
                   CommandParameter="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}, Path=CurrentItem}">
                    <TextBlock Text="{Binding dataName}" />
                </Hyperlink>
            </TextBlock>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

If I click the cell the hyperlink is in, and THEN click the hyperlink, everything will work fine. But that's not a really good workflow...if the user clicks the hyperlink it should have the right item...

I've solved my own issue, thanks for the help guys (lol)

Anyways, just for the fact that this might help someone later down the road, I didn't use CurrentItem since it doesn't seem to be updating correctly when I click a hyperlink. Instead, I gave the data I needed for the command as a command parameter.

So, the command actually only used the name of my data item, so instead of passing the whole data item (current item), I passed the name instead, and it works fine now.

<Hyperlink Command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}, Path=DataContext.NavigateToFormCommand}"
                   CommandParameter="{Binding dataName}">
