.NET manages the garbage collection automatically. You don't have to worry about clearing the objects. This will be done by .NET runtime automatically. But some classes implements IDisposable interface, which should be disposed by calling Dispose() method manually.

For this you need to keep one primary column on your datatable. When binding to gridview make this column to invisible. Eventhough it is invisible, you can access it by specifying the cell. So when delete button got click, you need to find out this hidden value. This will be the key for the record to be deleted.

use DataKey property of the gridview to access the ID value and to delete a particular record set the Command Property of the Delete Button as "Delete" and use GridView.RowCommand Event and put your delete code there...

Did you set the datakeynames property in the GridView? something like this...

asp:gridview id="GridView1" datasourceid="GridView1Source" <br />
        autogeneratecolumns="true" datakeynames="ID" runat="server">

If yes then In the GridView.RowCommand Event you can access the ID value using the below statement

GridView1.DataKeys[rowIndex].Value

try this...

Try this:

Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
Try
Dim oGridViewRow As GridViewRow
oGridViewRow = CType(CType(e.CommandSource, Control).NamingContainer, GridViewRow)
ID = CInt(GridView1.DataKeys(oGridViewRow.RowIndex).Value)
If e.CommandName = "DeleteTrans" Then
DeleteRecord(ID)'Function for delete the selected record
BindGridView()'Bind Gridview again
End If
Catch ex As Exception

End Try
End Sub

Hope this helps u??

Getting last ID after an insert statement

you have to give a primary key field as datakey field of datagrid.
asp:DataGrid ID="dgrdProducts" DataKeyField="ProductID" OnDeleteCommand="dgrdProducts_DeleteCommand" Runat="Server"
.
.

Then in code file

void dgrdProducts_DeleteCommand( Object sender, DataGridCommandEventArgs e )
{
int intProductID;
intProductID = (int)dgrdProducts.DataKeys[e.Item.ItemIndex];
}

using intProductID you can delete record from database.

You can refer to the help available with Visual Studio Web Developer Express Edition 2005. It has a walkthrough on encrypting and decrypting connection strings in web.config.

How to limit Http handler usage ???

In my site I need to use ajax(HttpRequest class) to let the user go through a process . In order to use ajax I have employed some http handlers. I need the requirement of limiting access to my http handlers to just users that are in the related page. Is there anyway to limiting access to http handlers ? If you recommend that I have to use something other than http handlers I appreciate it .

Thanks in advance
