Forms Data Controls :: Auto-Update Gridview Based On LastWriteTime Of File On Driveshare Via Client Side?
Jan 10, 2011I have a page setup that displays a datagrid connected to a access database file. I setup a timer to compare the last write time of the access db file and current time (with in 4 seconds). Once the times are with in 4 seconds of each other it requests a refresh of the data. The webpage is displayed on 4 thin client PC's with 0 user involvement so the WebPages need to update themselves. Due to the fact I'm limited to Access I'm trying to limit the # of times a day they are accessed by the auto-update.
The problem I'm having is when the timer ticks it POSTs to the web server. I have 3 WebPages setup watching 3 DB's for different location where I work but they all run of an IIS server in my office. So this creates a lot of unneeded traffic and log files. (Currently 5-6megs per day)
I was wondering there is a better way to compare the files on the clients machine and only post back for an update when they are with in 4 seconds of each other.
The site is built with MS visual web dev 2010 express written in Aspx and code lang is VB. I'm using system.io.file.getlastwritetime to get the file information for comparing.

Forms Data Controls :: DetailsView BoundFields Auto Binding Not Updating Business Object On Update
Feb 18, 2010I have a DetailsView (DV) control, an ObjectDataSource (ODS) control, and a button on a page. I have 2 classes in the App_Code directory (Customer and CustomerDAO). The DAO class provides static methods for the ODS control and simply hack values in (ie...no real database selects/updates). The Customer class has 2 properties (Id and Name) and a default constructor. The page takes an ID on the querystring and determines if the DV control is in insert or edit mode. If in edit mode, it sets the SelectParameter on the ODS (id field), calls ODS.Select(), and then calls DV.DataBind(). The existing (although fake) customer is loaded and display properly when this happens. I then change the name of the Customer in the DV and click the Button to save the new data.
Everything seems to be wired up correctly as the UpdateMethod that is specified in the ODS control is called and succeeds (even in my real example with my database). The problem is that the BoundFields in the DV control have not been updated with the new values and therefore the existing values are updated in the database and my changes are lost. I have handled the OnUpdating event of the ODS and the values are still the old values. I have also handled the OnItemUpdating event of the DV control and the NewValues IOrderedDictionary still has the old values in it also. In looking at the MSDN article for the UpdateMethod, it states the following:
Parameter Merging
Parameters are added to the UpdateParameters collection from three sources:
From the data-bound control, at run time.
From the UpdateParameters element, declaratively.
From the Updating event handler, programmatically.
I am using the BoundField classes in my DV control so I would have assumed that the first bullet above would have handled the updating of values, but it doesn't appear to work with the way I am doing it. If I set the values explicitly in the OnUpdating event that is fired by the ODS control (the 3rd bullet) the right values are updated (again...even in my real database situation). It seems like my only issue is that the automatic binding that I expect from the DV control isn't working as I would expect it to. Here is the code that I have in my fake example:
