Select whole column

[Andi]

Hi there,

is there any way to select a whole column by clicking the column-header?
I can not find any option to do that.

Hi Andi,

 Currently there is not such built-in feature however you can implement it very quickly if you declare for example a CheckBox in the column Header property and treat this column as "selected" if the CheckBox is checked. You can also assign different background for the "selected" columns - more info on this demo. 

Best wishes,

Still one question.

How will I place a Checkbox into my Header? My Columns where defined by Runtime from Code:

private void AddGridViewDataColumn(string uniqueName, bool insert = false)
{
  Binding bind = null;
  if (uniqueName != " ")
  {
    bind = new Binding(uniqueName);
  }
  else
  {
    bind = new Binding("col1");
  }
  bind.Mode = BindingMode.TwoWay;
  bind.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
  GridViewDataColumn column = new GridViewDataColumn();
  if (uniqueName != " ")
  {
    column.UniqueName = uniqueName;
  }
  else
  {
    column.UniqueName = "col1";
  }
  column.Header = uniqueName;     // LocalizationManager.GetString(uniqueName);
  column.DataMemberBinding = bind;
  column.CellEditTemplate = (DataTemplate)FindResource("SyncToBoxTemplate");

  if (insert)
  {
    int index = rgvEntscheidungstabelle.Columns.Count - 1;
    this.rgvEntscheidungstabelle.Columns.Insert(index, column);
  }
  else
  {
    rgvEntscheidungstabelle.Columns.Add(column);
  }
}

Hi Andi,

This help topic demonstrates how you can customize column headers. 

Hope it helps.

Thank you Milan.

For all who want's to add a Column with Checkbox in the Header by Runtime, this is the Code you can use (and make better):

StackPanel p = new StackPanel();
p.Orientation = Orientation.Horizontal;
CheckBox cb = new CheckBox();
cb.VerticalAlignment = System.Windows.VerticalAlignment.Center;
Label l = new Label();
l.Content = uniqueName;
p.Children.Add(cb);
p.Children.Add(l);
column.Header = p;
