C# - GridView Isn't Updating Properly

I have a Gridview with these parameters:

<asp:GridView runat="server" ID="ItemGrid" CssClass="Grid"
AutoGenerateColumns="false"
AutoGenerateDeleteButton="true" OnRowDeleting="RowDeleting"
AutoGenerateEditButton="true" onRowEditing="RowEdit"
OnRowCancelingEdit="CancelRowEdit" onRowUpdating="RowUpdating"
DataKeyNames="Item_ID">
<Columns>
<asp:BoundField HeaderText="Item" DataField="Item"/>
<asp:BoundField HeaderText="Family" DataField="Family"/>
<asp:BoundField HeaderText="Structure" DataField="Structure"/>
<asp:BoundField HeaderText="Updated" ReadOnly="true" DataFormatString="{0:d}" DataField="Updated"/>
</Columns>
</asp:GridView>


On updating it calls:

protected void RowUpdating(object sender, GridViewUpdateEventArgs e){
int Item_ID = (int)this.ItemGrid.DataKeys[e.RowIndex][0];[code]...

It generates the Update/Edit/Delete buttons, my Delete function is working exactly how I want and the 'Edit' button generates editable TextBoxes as it should.

My problem is in the updating part, the strings Item, Family, Structure are getting the old values, not the new values I put in the generated text boxes.If I hard code in values they are updated to the database and the DateTime.Now is always updating correctly in the database so the update query is working.

I've been looking at this/reading forums testing things for a couple days now. I'm sure I'm just missing something simple that I have overlooked.

Edit:It has been answered but for those who were curious this is my dataBind();

protected void dataBind()
{
ItemTableAdapter taItem = new ItemTableAdapter();
this.ItemGrid.DataSource = taItem.GetActive();
this.ItemGrid.DataBind();
}
