updating table with dataadapter

I feel like this should be easy....

I have a web form with a data adapter and a datagrid. I simply want to be able to use the data grid link buttons for edit, update, etc to modify my database table.

I can edit the row on the web form, but the update code nevers seems to get run against the database (I am using SQL Profiler so I know the code never hits the DB). Shouldn't this happen when I call the update method of the sql data adapter ?!?

I used the data adapter wizard to generate the update, delete commands (I know I could do this other ways but now I want to solve this problem). Here are my relevant event handlers:

VB Code:

Private Sub grdItems_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles grdItems.EditCommand
        grdItems.EditItemIndex = e.Item.ItemIndex
        grdItems.DataBind()
    End Sub
    Private Sub grdItems_UpdateCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles grdItems.UpdateCommand
        adpMatDwg.Update(dsItems, "UDTMaterialDrawing")
        grdItems.EditItemIndex = -1
        grdItems.DataBind()
    End Sub

Thanks in advance!

every time the page refreshes, the dataset is lost. you will have to refill the dataset, find the specific row based on a column in the datagrid that holds the unique ID, do your field assignments, update and rebind the dataset to the datagrid.

dim txtName as TextBox
txtName = e.item.cells(1).Controls(0)
da.fill(ds, "tblTable")
row = ds.tables("tblTable").rows.find(e.item.cells(0).text)

row("Name") = txtName.Text

da.Update(ds, "tblTable")
ds.acceptchanges

dgr.DataSource = ds
dgr.DataBind()
