Gridview rowupdating event in asp net c


12-Jul-2017 13:46

He visto en reiteradas oportunidad que una operación simple como es el caso de operar con una fila de un Grid View se puede transformarse en algo complejo, mas que nada motivado por la distintas formas que hay para realizar esta acción.

En este articulo veremos las algunas formas de lograrlo y como difieren las técnicas que se puede aplicarse.

Save all or press "Ctrl S" and hit "F5" to run the page, the page will look as in the following image: Click on "Edit the Grid View", it will display Textboxes in each cell as in the following image: Edit the value(s) here and click on the Update link, it will update all the data or to remove it click on the "Delete" link above the image shown.

One note will be helpful for you, while describing Columns in Grid View if you are using a boundfield then create objects of the control using cells[index] in the rowupdateing event of Grid View, but if you are using controls itself like Label or textboxes etc then use Fincontrol("stringid").

I'm confused about the ordering of events CAn you show me where tis fits in to the code I had been working on: protected void Grid View1_Row Data Bound(obj no same as before my grid changes when I click edit and I see my dropdowns etc populated with the original selections - I can change all my editable fields but when I click on Update I still get the error cannot find control DDLCategory Edit in Control Parameter Edit Category ID - my Update parameters below in case they are at fault: My apologies for such a long delay, I think I've led us on a bit of a wild goose chase.

When I set up my databound grid I hadn't called up the key identity so as soon as I started to call up row related changes of course I was running into the problems above.

The columns can be pre defined columns like Check Box Field, Image Field etc. The following example shows creating a grid with edit and delete buttons on right for a table with name DEPT having three columns DEPTNO, DNAME and LOC.

The idea is to only allow a command to be performed on specific people. I'd prefer a declarative solution to a procedural one. For me converting the commandfield to a templatefield control is not an option, as the commandfield comes with built-in functionality that I would otherwise have to create myself, for example the fact that it changes to "Update Cancel" when Edit is clicked, and that when Edit is clicked, all the cells in the row which are labels become textboxes, etc.

Existen varias formas de realizar una misma tarea, pero veremos aquí las dos mas simples y directas que se suelen encontrar cuando se necesita seleccionar un registro en el control gridview.aspdotnet-suresh offers C#articles and tutorials,csharp dot net,articles and tutorials, VB.
