How to show different context menu for each column in WPF DataGrid?
WPF DataGrid (SfDataGrid) allows you to set different ContextMenu for each column using the SfDataGrid.GridContextMenuOpening event.
Refer to the following code example to define different ContextMenu for each column based on the column index in SfDataGrid.GridContextMenuOpening event. Here, the first three columns have different ContextMenu and the rest of columns have different ContextMenu,
this.AssociatedObject.GridContextMenuOpening += AssociatedObject_GridContextMenuOpening;
private void AssociatedObject_GridContextMenuOpening(object sender, GridContextMenuEventArgs e)
{
e.ContextMenu.Items.Clear();
var columnIndex = this.AssociatedObject.ResolveToGridVisibleColumnIndex(e.RowColumnIndex.ColumnIndex);
if (columnIndex < 0 && columnIndex >= this.AssociatedObject.Columns.Count)
return;
var column = this.AssociatedObject.Columns[columnIndex];
if (column == null)
return;
List<object> commandParameter = new List<object>();
commandParameter.Add(this.AssociatedObject);
commandParameter.Add(column);
CommandBinding binding = new CommandBinding();
this.AssociatedObject.CommandBindings.Add(binding);
if (columnIndex < 3)
{
e.ContextMenu.Items.Add(new MenuItem()
{
Header = "AddSort",
Command = ContextMenuCommands.AddSort,
CommandParameter = commandParameter
});
e.ContextMenu.Items.Add(new MenuItem()
{
Header = "AddGroup",
Command = ContextMenuCommands.AddGroup,
CommandParameter = commandParameter
});
e.ContextMenu.Items.Add(new MenuItem()
{
Header = "ClearSort",
Command = ContextMenuCommands.ClearSort,
CommandParameter = commandParameter
});
e.ContextMenu.Items.Add(new MenuItem()
{
Header = "ClearGroup",
Command = ContextMenuCommands.ClearGroup,
CommandParameter = commandParameter
});
}
else
{
e.ContextMenu.Items.Add(new MenuItem()
{
Header = "Copy",
Command = ContextMenuCommands.Copy,
CommandParameter = commandParameter
});
e.ContextMenu.Items.Add(new MenuItem()
{
Header = "Paste",
Command = ContextMenuCommands.Paste,
CommandParameter = commandParameter
});
}
}
