how to set the datagridview columns to allow user to click to sort

[AboutJAV]

Hi,

I have a datagridview with 3 columns. the grid selectionmode is set
to

this.grid.SelectionMode =
System.Windows.Forms.DataGridViewSelectionMode.FullRowSelect;


I even set the columns sort property to

System.Windows.Forms.DataGridViewColumnSortMode.Automatic


When the form is loaded and any of the 3 columns are clicked, nothing
happens. The data does not reordered in any directions.

Any advice is appreciated.

Thanks,

What is the DataGridView bound to, or is it unbound?

The datagridview is bounded to an object with a collection.

The datagridview is bounded to an object with a collection.

You'll have to be more specific about the collection that you're using..
eg: by default a BindingList<T> does not support sorting.

A websearch will return you many valueable resources with
implementations of collections that do allow sorting. Even i was
able to write a SortableBindingList<T>
