Hi to all,

I use the wpf datagrid control in a master / detail szenario (bound to a dataset with 4 levels). I need to show and hide the insertionrow of each level by code (button click of a button in a header datatemplate of each level). How can I achieve this in code?

 Thank you for your help or any hint you can give me!

Hello,

    You can create the datatemplate for the insertion row and add and remove it dynamically:

Datatemplate for insertion row:

  <DataTemplate x:Key="InsertionRow">
          <xcdg:InsertionRow  ReadOnly="False"
                                Loaded="InsertionRow_Loaded"
                                EditEnded="InsertionRow_EditEnded"
                                EditEnding="InsertionRow_EditEnding"
                                EditBeginning="InsertionRow_EditBeginning" 
                                Background="Transparent"
                                EditTriggers="CellIsCurrent"
                                Margin="1"/>
                
        </DataTemplate>

Button Click Event Adding/Removing:

 private void btnAdd_Click(object sender, ExecuteRoutedEventArgs e)
        {
                 try
            {
                   if !TblView.Headers.Contains((DataTemplate)this.Resources["InsertionRow"]))
                {
                    this.TblView.Headers.Insert(0, ((DataTemplate)this.Resources["InsertionRow"]));
                                    }
                else
                {
                    this.TblView.Headers.Remove((DataTemplate)this.Resources["InsertionRow"]);
                    if (btnAdd != null)
                    {
                        btnAdd.IsChecked = false;
                        IsInsertion = false;
                    }
                }
            }
            catch (Exception)
            {


            }
        }

 whereTblView is property

   public TableflowView TblView
        {
            get
            {
                return View as TableflowView;
            }
        }
 

 Thanks,
