ASP.NET 2 GridView.

[realgeek]

I got to playing with ASP.NET 2.0. So I have the following code:
CODE
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="QuestionID"
OnRowCancelingEdit="GridView1_RowCancelingEdit"
OnRowEditing="GridView1_RowEditing"
OnRowUpdating="GridView1_RowUpdating">
<Columns>
<asp:BoundField DataField="Description"
HeaderText="??????"></asp:BoundField>
<asp:CheckBoxField DataField="IsActive" HeaderText="???." />
<asp:CommandField ButtonType="Image"
CancelImageUrl="img/button_cancel.png" EditImageUrl="img/edit.png"
ShowEditButton="True" UpdateImageUrl="img/button_ok.png" />
</Columns>
</asp:GridView>


In .cs file:
CODE
SqlDataSource ds;

protected void BindData()
{
ds = new
SqlDataSource(WebConfigurationManager.ConnectionStrings["AnketaDBConnectionString"].ToString(),
"SELECT QuestionID,Description,IsActive FROm Question");
GridView1.DataSource = ds;
GridView1.DataBind();

}

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindData();
}
}

protected void GridView1_RowUpdating(object sender,
GridViewUpdateEventArgs e)
{
Response.Write(e.Keys.Count.ToString());
Response.Write(e.NewValues.Count.ToString());
}

protected void GridView1_RowEditing(object sender,
GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
BindData();
}

protected void GridView1_RowCancelingEdit(object sender,
GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
BindData();
}

You see that it outputs number of keys and new values on update.
Problem is, both numbers are zero when I press edit, preform editing
and press ok, I cannot update anything. What's wrong with that?

If you want to the grid to do automatic updates back to the database you
need to use the new declarative databinding model. SO, IOW, you need a <asp:SqlDataSource>
and to set the DataSourceID on your GridView.
