Hi Kurt,

In runtime when you rearrange the columns actually you don't change the layout.

In order to change the Fields Rows and Cols arrangements from Code Behind you have to replace the default FieldLayout  with a new one. You can do it like this: 

1. Set the XamDataGrid.DataSource to null;

2.Remove the default FieldLayout

3.Add a new custom FieldLayout  (with the desired Rows and Cols) to the FieldLayouts

4.Set the AutoArrangeCells property of the XamDataGrid to "Never"

5.Rebind the XamDataGrid.DataSource

 private void btnChangeLayout_Click(object sender, RoutedEventArgs e)
{
    FieldLayout layout1 = new FieldLayout();
    Field f1 = new Field();
    f1.Name = "FirstName";
    f1.Row = 0;
    f1.Column = 0;
    Field f2 = new Field();
    f2.Name = "LastName";
    f2.Row = 1;
    f2.Column = 0;
    layout1.Fields.Add(f1);
    layout1.Fields.Add(f2);     

 

    xamDataGrid1.DataSource = null;
    xamDataGrid1.FieldLayouts.Remove(xamDataGrid1.FieldLayot[0]);
    xamDataGrid1.FieldLayouts.Add(layout1);
    xamDataGrid1.FieldLayoutSettings.AutoArrangeCells =  AutoArrangeCells.Never;
           
    xamDataGrid1.DataSource = customers;
    xamDataGrid1.UpdateLayout();
}

Also you can create a custom FieldLayout in xaml as Resource and then do the same steps to change the FieldLayout:

FieldLayout layout = this.FindResource("customLayout") as FieldLayout;

Best regards

Hi Vlad,

Thank you for the quick reply.  I got it working by just modifying the fields in place.  Re-creating them with all the same info used to build them with templates the first time would be a lot of info to save off.  Here is all I had to do to stack them 2 rows deep.

FieldLayout newLayout = dataGrid.FieldLayouts[0];
for (int i=0; i<dataGrid.FieldLayouts[0].Fields.Count; i++)
{
    dataGrid.FieldLayouts[0].Fields[i].Row = i %2;
    dataGrid.FieldLayouts[0].Fields[i].Column = i / 2;
}

dataGrid.DataSource = null;
dataGrid.FieldLayouts.Remove(dataGrid.FieldLayouts[0]);
dataGrid.FieldLayouts.Add(newLayout);
dataGrid.FieldLayoutSettings.AutoArrangeCells = AutoArrangeCells.Never;

dataGrid.DataSource = bindingSource;
dataGrid.UpdateLayout();

 Thanks again!
