Binding a ComboBox's SelectedItem or SelectedValue which resides inside a DataGrid

Question

I have a DataGrid. Let it have two columns name and Gender :

<DataGrid............>
    <DataGridTemplateColumn Header="Name">
        <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <TextBox Text="{Binding Name, RelativeSource.........}" />
            </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
    <DataGridTemplateColumn Header="Age">
        <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <ComboBox SelectedItem="{Binding Selected, RelativeSource.........}" >
                    <sys:String> Male </sys:String>
                    <sys:String> Female </sys:String>
                </ComboBox>
            </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
</DataGrid>

Now When I run the program, and suppose I have 5 rows in the DataGrid, thenwhen I select male in any row e.g. 3rd row, then all the combobox's SelectedItem becomes Male. How can I avoid this?

When my program runs I have only 1 row, But when I add more rows it looks like :

When I try to select Female in any ComboBox :

When I select Female in any ComboBox :

I know that my Binding is Incorrect, so I am facing such a problem, but can anybody explain me the ComboBox's SelectedItem Binding inside a DataGrid?

Could you show the entire definition of SelectedItem binding? And what is the ItemsSource of the DataGrid? — vadim
@RohitVats Selected Property resides in GroupsViewModel. — Vishal
So, you are binding all rows with same property. You should bind with the property in underlying source if you want it to be set individually for all rows. — Rohit Vats

Since you are trying to bind List and you have ComboBoxItem objects as items. Set your ComboBox SelectedValuePath="Content" like this

 <ComboBox SelectedValuePath="Content" ....... >
                    <sys:String> Male </sys:String>
                    <sys:String> Female </sys:String>
  </ComboBox>
