| Hi Andrew,
|
| Welcome to ASPNET newsgroup.
| As for the template databound controls such as GridView/DetailsView, and
| the original DataGrid and DAtaList ...., the DataSource instance
(DataSet,
| DataTable ...) only exist when the datacontrol is performing databinding.
| After that, the datasource instance no longer exist in the sequential
| request, the datas are persisted in the control through ViewState. So we
| can not directly obtain the original DataSet/DataTable back from The
| databound control on the page. If you're wantting to retrieve the updated
| values (of the controls) in each row and do manual data updating, we have
| the following options:
|
| 1. We still use the DetailsView control's buildin updating mechanism, but
| use the ItemUpdating event to proprocess the update operation. The
| ItemUpdating event, we can get the paramters that will be used to do the
| updating operation and then use them to perform our own update operation.
| And we can use the
| DetailsViewUpdateEventArgs.Cancel to cancel the buildin update operation.
|
| 2. If we don't want the utilize the buildin events, we can use the
| DetailsView.Rows and DetailsViewRow.Cells collection to manually retrieve
| the values from the Bounded control's Text Property. Like:
|
| protected void Button1_Click(object sender, EventArgs e)
| {
| Response.Write("<br>DetailsView1.Rows.Count: " +
DetailsView1.Rows.Count);
|
| foreach (DetailsViewRow dvr in DetailsView1.Rows)
| {
| Response.Write("<br>dvr.Cells.Count: " + dvr.Cells[1].Text);
| }
| }
|
| However, all the above options can only retrieve the values for the
| currently active (displayed ) record. Unlike the DataGrid, GridView,
| DetailsView dosn't provide the direct interfaces for loop through all the
| records's data.
|
| Thanks,
|

| | Is there any way to accomplish two way data binding in a Details View
| with a
| | DataSet or DataTable as the DataSource.
| |
| | All I want is to get an updated DataSet or DataTable back from the
| | DetailsView and then handle my updating manually.
