Access Objects I've Assigned To Repeater.DataSource?
Jul 15, 2011I have a Repeater Control which I bind to a list of Products
Repeater.DataSource = ProductRepository.GetProducts();
Later (in another module), I need to retrieve the products from the Repeater, but it seems not to work with Repeater.Item.DataItem (which is then null).
My question is, is there any reference to the products in the Repeater-Items? Or do I have to set it myself via id field etc. What would be the easiest way to get the "underlying" product objects?

View 1 RepliesDatagrid With Joined Tables As Datasource Bindingsource?
Sep 25, 2011When I update a record at table [Product] with the integer that stands for [Supplier Name] from joined table [Suppliers], this does not appear in my datagridview. Instead, I have to reload the table to dataset to make it visible. What about datarelation? Is it better that loading a joined table over the dataset? Note that I have never dealed with datarelations before.. How can I make a datagrid column to show "Supplier Name" instead of recordID that represents this supplier?

Extra Row In Datagrid When Using Filtered Dataview As Datasource?
Jun 9, 2009I am filtering a dataview which is used for a datagrids datasource.At runtime when I apply the filters (using Checkboxes to determine the RowFilter text) I get an additional blank row at the top of my grid. This is then treated like a row & is filtered out with other rows that don't fit the filter criteria but comes back when I remove the filter. Basically, its part of the underlying DAtaview it seems. It's not persisited to database but I can't seem to get rid of it when I'm filtering.

Feb 17, 2012It's my first time playing with the DataGridView properly and I've hit a little snag...I need to display data in a DataGridView for ease of viewing, and I have a list of all the data. It's a list (of a structure), and I've got no idea how to do this. I can set the datasource as the list, but that doesn't work. I've read up on the topic but don't really understand. Am I forced to use classes not structures in this instance?

Error Checking On Datagrid
Aug 13, 2009I need to validate that a user doesn't leave the name field blank when they add a record in a datagrid. See code below that I wrote to accomplish this. It works fine if the code is under the 'saveitem' event. However, I want to check it each time a row has been entered (the user may add several records before clicking on the save button). I tried putting it under the 'Row Leave' event but apparently that event "fires" when you click the add button and throws up the error message immediately. I thought about doing it on 'cell' leave but then could not figure out how to determine which cell column you are leaving in order to check the appripriate field.[code]...

View 6 RepliesVS 2005 Checking Database For Row
Apr 25, 2009I have a program which is almost complete, it gets data that is new or newly modified (well at least since my program last got this data). The problem I have is currently i'm adding this "new" data but i've just clicked some of this data may be in my database already just updated. For example, I have added some user data to my database but a user has just updated their user name - so this is now newly modified! I don't want to add it as new data I want to update my current row in my database. My question is how can i do a SQL query in my access database to see if this row exists or not?

Is there a better way to see if a row already exists using specific columns and key indexes?
