C# - GridView - How To Perform Custom Update Statements

I have an ASP.NET GridView which displays a list of neighborhoods.

I wish a user (administrator) to be able to edit the neighborhood name.

Now, the database is quite complex, and as such, i can't simply provide an UpdateCommand / SqlDataSource for the GridView.

I bind the data manually (on first load, and on the PageIndexChanging event).

Binding/listing paged data is working fine.

However, i'm having trouble trying to UPDATE the data.

The user clicks the "Edit" button, the textbox for the neighborhood name is shown, i change the text, click "Update", but the RowUpdating event is not firing.

I basically want to grab the row that was edited, and perform a custom update using LINQ.

Is this not possible with a GridView? If it's not, what are my alternatives? A repeater with LinkButtons and a hidden textbox that can swap in/out the labels?

This is my GridView markup:

[Code]....

And the code-behind:

protected void NeighborhoodsGridRowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow updatedRow = NeighborhoodsGrid.Rows[e.RowIndex]; // not firing. =(
}

I also have the GridView wrapped in an UpdatePanel, if that makes any difference (don't think it should).
