Question

I am using WPFDataGrid control and want to set keyboard focus to selected Cell by single-click.By deafault user must double-click cell to start writing.i’ve tried the code be:

<Style TargetType="{x:Type DataGridCell}" x:Key="DataGridCellStyle">
   <Setter Property="IsTabStop" Value="True" />
   <Setter Property="Focusable" Value="True" />    
   <Style.Triggers>
      <Trigger Property="IsKeyboardFocusWithin" Value="True">
        <Setter Property="IsEditing" Value="True" />
      </Trigger>
   </Style.Triggers>
</Style>

When i click on a cell,it get to Editmode,and i need to click again to set keyboard focus there and start writing!

I ‘m not sure if this a nice feature. You might not be able to select multiple cells. anyway handle OnCurrentCellChanged event

void DG1_OnCurrentCellChanged(object sender, SelectedCellsChangedEventArgs e)
{
    DataGrid dg=(Datagrid)sender;
    dg.BeginEdit();
}

BeginEdit() cause DataGridPreparingCellForEdit event to occure, I think you should handle that event:

private void dg_PreparingCellForEdit(object sender,  DataGridPreparingCellForEditEventArgs e)
{
TextBox tb = e.EditingElement as TextBox;
if (tb != null)
   {
       tb.Focus();
       //you can set caret position and ...
   }
}

also, you can handle BeginningEdit event.
