Devexpress gridview rowupdating error who is he dating

Instead, take out the Command Argument and change the Command Names of each button to what they default to in the Grid View (ie: Select, Edit, Update, Cancel, Delete). For instance, if your item template has an image button that is set up with a command name of "Delete", it will automatically fire the On Row Deleting event for the Grid View when clicked.An example is below: The biggest benefit (in my humble opinion) is that you can handle both the gridview events AND the imagebutton events, abstracting any business logic associated with clicking the button even further.

It closes off the bottom of the Details View nicely. meanwhile, I have a go with this workaround (converting the Command Field column to Template Field) [cool] but I've got a strange error: Invalid postback or callback argument. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. I have a solution to this issue that is probably the cleanest I have seen. I was close to resign to this dumb ASP problem, but then I found this solution. The only problem is, you can't change the Command Name if you use those special fields. Row Command And now when I was cliking Edit Button in grid I was facing the same problem... "Note: the example above shows how you can pass a value of another column on the same row that you wish to delete (ex: item_id is a field of another column in the same row) to your event handler that can help you delete a record from the database. I was struggling with the command field of image type for some time, and with postbacks going twice..If the data is valid and expected, use the Client Script Manager. I will allow you to make the fewest changes to your code and continue using the Row Deleting and Row Deleted events for the Grid View. But for any other action not covered by Command Button I use the other solution and put the Primary Key into the Command Argument using the Eval function... Couldn't use template field either because I got the dreaded "Invalid postback or callback argument".By Changing the Button Type to "Link" and modifying the Delete Text you will have the same delete image that works exactly like the Image Button Type but without the double firing event. [Yes] Also - for confirmation boxes on those things, the new AJAX toolkit from Microsoft has a button confirmation control that's easy to use.Same result as that simple code above, but a little more "design-timey" (and probably a lot more fat on the client with all those scripts, but eh, who cares about that now that everyone has fiber into their homes :-p). Not only do you get a performance hit, but it makes your code ugly (don't even get me started on the repeater control).Ayer martes por la mañana, uno de mis amigos me pidió ayuda con la grilla para web de Visual Studio 2005 (Grid View), me dijo que no puede realizar actualizaciones de datos haciendo el enlace en tiempo de ejecución, es decir hacer todo por código, sin utilizar los componentes en tiempo de diseño con lo que se puede hacer la actualización de datos en pocos minutos.

Le dije () no hay problema, en 20 minutos te mando un ejemplo completo; antes había trabajado de esta manera con el Framework 1.1 y el componente Data Grid sin ningún problema, pero grande fue mi sorpresa al ver que con el Grid View las cosas se complicaban enormemente y algo que parecía tan básico no lo era tanto al menos para mi, luego de revisar muchas páginas con ejemplos, casi reventar el monitor con la cabeza y 3 horas de trabajo, al fin logré hacer andar el bendito ejemplo, a continuación algunas pautas para no enloquecer en el intento: 1.Convertir las columnas en Plantillas.- Para facilitar el trabajo de recuperar los datos del registro que se esta editando, es necesario cambiar los tipos de columnas de Bound Field a Template Field, de esta manera podremos recuperar los datos que se están ingresando en cada uno de controles de la plantilla, utilizando el método Find Control. Implementar los eventos del Grid View que necesitemos.- Esta parte es muy importante, puesto que en estos eventos tendremos que poner toda la lógica para realizar la actualización de datos, los eventos más importantes que tenemos que interceptar son: Row Editing, Row Updating, Row Canceling Edit y Row Deleting.//método auxiliar para facilitar el trabajo de enlace a datos void Enlazar Datos() void Grid View1_Row Editing(object sender, Grid View Edit Event Args e) void Grid View1_Row Updating(object sender, Grid View Update Event Args e) void Grid View1_Row Canceling Edit(object sender, Grid View Cancel Edit Event Args e) void Grid View1_Row Deleting(object sender, Grid View Delete Event Args e) Atención, el código que se muestra es solo un ejemplo, por simplicidad está sin las validaciones necesarias (por ejemplo comprobar que no sean nulos algunos objetos).However, now that the event triggering twice is solve. Seconds For what it's worth my solution/dirty hack ' Declare a global boolean Public exit Sub As Boolean = False Sub Dothis Once(blah, blah) If exit Sub = True Then Exit Sub End If ' Do some coding/DB work or something ' code has ran so set boolean to true Here's a link to some information regarding Microsoft's awareness of this bug and a fairly good workaround that doesn't involve hacky flags: View_commands_ _Auto Event Wire Up Thanks for reporting the issue.But the funny part is (for me) the event turned out to be inconsistance in its behaviour (i.e. And if someone else also facing similiar inconsistance behaviour, I'd advice to do like what I'll hopefully do; which is letting the user select the rows and clicks on a button (outside the grid) to delete them instead of embeded delete button within each row. Seconds Private Function Ok2Delete(By Val p Row As String) As Boolean If Session("Row Index") Is Nothing Or Else _ (CInt(Session("Rowindex")) = p Row And Also Date Time. This is a known issue and we are investigating fixing this in the next service pack.Si necesitan revisar un ejemplo totalmente funcional pueden descargar el ejemplo que hice para mi amigo, funciona con la base de datos Northwind con los tres primeros campos de la tabla Employees, utiliza la clase Sql Data Source, también se puede hacer con la clase Sql Data Adapter, pero como estamos trabajando con el .
