should help you out You may need to write a converter for this, which returns a string value of A1 when input value is true and A2 if input is false.
code :
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if((bool)value == true)
      {
          return "A1";
      }
        else
      {
          return "A2";
      }
    }

it helps some times You can hook into the ItemDataBound event. In here, you can FindControl() for your nested DataGrid and bind that on the fly.
code :
protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
{
    DataGrid child = e.Item.FindControl("theNestedGrid") as DataGrid;
    if(child != null)
    {
         // Binding logic here
    }
}

around this issue Simply call that function after dropdown list binding: BindTooltip(Name of the dropdownlist);
code :
public void BindTooltip(ListControl lc)
{
    for (int i = 0; i < lc.Items.Count; i++)
    {
        lc.Items[i].Attributes.Add("title", lc.Items[i].Text);
    }
}

This might help you DataGrid is binded to some DataTable. User changed some values. I want to mark changed row with some color. I've done it. But how to notify DataGrid, that current row values have been changed? , Not the best decision but it works as I expect:
code :
dataView.ListChanged += (o, e) =>
{
    if (e.ListChangedType == ListChangedType.ItemChanged)
    {
        DataRowView row = ((DataView)o)[e.NewIndex];
        if(row != null)
        {
            MethodInfo method = typeof(DataRowView).GetMethod("RaisePropertyChangedEvent", BindingFlags.Instance | BindingFlags.NonPublic);
            method.Invoke(row, new object[] { "Row" });
        }
    }
};

it fixes the issue I have been stuck in the DataGrid styling for hours. I have searched many solutions but to no avail, I haven't been able to apply the styling on my design.
code :
//may it help don't need to code in .cs just in .xaml
//just add your properties in binding let me know if any error

 <DataGrid.RowStyle>
    <Style TargetType="DataGridRow"> 
        <Style.Triggers>
            <DataTrigger Binding="{Binding _age}" Value="20">
                <Setter Property="Background" Value="Red"></Setter>
            </DataTrigger>
            <DataTrigger Binding="{Binding _ismale}" Value="true">
                <Setter Property="Background" Value="Green"></Setter>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</DataGrid.RowStyle>
