What i want now when my this windows loads, I want to set keyboard focus to first cell of OpenStock column and if possible in edit mode. I searched this for 2 days and finally posting here.

<my:DataGrid AutoGenerateColumns="False" ItemsSource="{Binding}" Margin="2,2,2,55" 
x:Name="dataGrid1" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Background="White"    
AlternatingRowBackground="AliceBlue" AlternationCount="2" SelectionMode="Single" 
SelectionUnit="Cell" BorderThickness="0" IsTabStop="True">
        <my:DataGrid.Resources>
            <Style x:Key="errorStyle" TargetType="{x:Type TextBox}">
                <Setter Property="Padding" Value="-2"/>
                <Style.Triggers>
                    <Trigger Property="Validation.HasError" Value="True">
                        <Setter Property="Background" Value="Yellow"/>
                        <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self},
                                Path=(Validation.Errors)[0].ErrorContent}"/>
                    </Trigger>
                </Style.Triggers>
            </Style>
        </my:DataGrid.Resources>
        <my:DataGrid.Columns>
            <my:DataGridTextColumn Width="60" FocusManager.IsFocusScope="False" Binding="{Binding Path=pCode}" Header="Code" IsReadOnly="True" />

Answer 1

You need to set the current cell to the one you want edited and then call BeginEdit in your Loaded handler:

dataGrid1.CurrentCell = new DataGridCellInfo(
    dataGrid1.Items[0], dataGrid1.Columns[3]);
dataGrid1.BeginEdit();

If you give your DataGridTextColumn a name in XAML you can use that name rather than Columns[3].

Use this code to move the scroll view to a specific cell:

dgv.ScrollIntoView(dgv.Items[row], dgv.Columns[col]);
