Data access use with textboxes

[Ruby]

Hi, I am usingTelerik data access for the first time. Initially I used it with radgrid and it worked fine.
Now , I have a web form with 10 textboxes getting data from open access query, I am not sure how to bind that data. I need something like datareader to bind data from the query.Based on the value selected from customer dropdown, my textboxes value should change. please guide me on this, Thanks.

Hello Ruby,

As I reviewed your code I noticed that you are filtering an OpenAccessLinqDataSource. This component actually returns a collections and it is appropriate to be used with list control such as the Telerik RadGrid.

On the other hand your referral to the datareaders suggests that you would like to query the data in the code-behind, apply any filters specified by the RadComboBox-es or perform additional logic on the retrieved data and data-bind to a number of text-boxes. 

If that is the case I would like to point you at this documentation article from the ASP.NET Development Section of our documentation. It describes the best practices when using Telerik Data Access context in an ASP.NET Application. Once you retrieve and process the data, it is a matter of the standard techniques of data binding in an .aspx page.

Additionally, I recommend you going through out samples kit. It contains a number of ASP.NET related examples that demonstrate those best practices in various scenarios.

If you have any more  questions or need any further assistance, please let us know.

Regards,
Boyan
