If you are not familiar of binding the Grid View the way then I would suggest looking at my previous example first before you proceed to this example. Parameter name: index Any idea what I need to do to fix this issue?

In this demo, I presumed that you already have a basic background on how to create a simple database table. Thanks that cmd do not work fine string id = Grid View1.

For the ease of understanding, I have created BAL, DAL into the App_Code folder. pre 2) Can you post other similar article with Ajax? Because in practice we expect the delete to be performed with confirmation and also in details screen. Add new / Edit in 2 different tab panels - to have better usability. Regards, Sreedhar Thanks Vansree for your suggestions. Regarding pre class, I will let the webmaster know about it. As far as article on Ajax is concerned, I will try my best to post few articles on Ajax in coming days. Regards This is simpler example for 3-Tier Architecture.

In real scenario, you should create separate projects for BAL, DAL (as Class Library) and UI (as Web project) and reference your BAL into UI. I wonder if you can come up with the same but using Ajax Tabs. Like having add button in Grid View will switch you to Tab Panel (Add new) and then perform the add ... But would like to see if you can come up with Tabs and your example above. I have one question about passing the data between layers.

Otra alternativa interesante podría ser el uso de la clase Bound Field con esta seria posible definir columnas en tiempo de ejecución, si bien podría ser la solución en la mayoría de los caso, esta no permite un control total del témplate que se debe usar en al edición de las columnas.

La solución definitiva al problema esta en la implementación de témplates de columnas, estas clases especializadas contendrán el código del témplate que define, para que esto se posible se necesitara implementar la interfaz ITemplate El modelo del ejemplo de código planteado hace referencia a dos listados, uno de notebooks y otro de televisores, ambos con distintas columnas por mostrar, pero haciendo uso de un solo control de grilla y la definición de las columnas de forma explicita en runtime.

NET with C# 3-Tier architecture generally contains UI or Presentation Layer, Business Access Layer (BAL) or Business Logic Layer and Data Access Layer (DAL). Independence - layers are established so that if one is modified (to some extent) it will not affect other layers. Reusability - As the layers are seperated, it can exist as a module that can be reused by other application by referencing it.

Suelen darse los escenarios en donde se necesite editar distintas entidades pero haciendo uso de un único control gridview.

Una respuesta rápida a este problema seria hacer uso de la propiedad Auto Generate Columns en true, para que los datos que se le proporciona al control defina las columnas que debe mostrar, lo malo de esta opción es que se pierde control sobre la grilla.

Nor does it represent the opinion of my dog, because I don’t have one. I have a project that I coppied the above code into. Data Keys[Row Index]["Customer ID"]in the Update event it would be something like:int Customer ID = Convert. Format Exception: Input string was not in a correct format.

This demo is a continuation of my previous example “Binding Grid View with Data”. When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values. Text; bit when ichange it to string id =((Text Box) Grid View1. Line 136: Source Error: Line 134: string Um = ((Text Box)Grid View1.
