Rowupdating oldvalues empty
Please note these property names are same as the ones in the ASPX file.[Dev Express Web Localized Description Attribute("Enables you to prevent a row from being updated.")] [Category Attribute("Eylem")] public: event Dev Express. Hi, I have problem in gridview rowupdating, e.newvalues("fieldname") return oldvalues. Anyone can help me pls, thx in advance regards, forza detailsview1 has 5 fields named Id, States, Page Title, Page Content, Is Active.Here's my code : protected sub Grid View1_Row Updating(By Val sender as object, By Val e as System. 1/ detailsview1 are working well at the time inserting data.How do I get this to work so that when I insert a new record, all old values are flushed. As String; and you could also do it on the form Key Press so that when they pres escape it just reloads the Edit1.I have tried applyupdates and commitupdates before calling insert. It also appears that Old Value only differs from newvalue until I leave the field. Xsys You could replace the TDBEdit with a regular TEdit then when the form is created or painted do a Edit1. I had though of a similar solution of using a query to hold the values of the existing record and update from the query when escape is pressed. I would like to add the functionalty either in one place per form or once in the parent form.This post explains how to perform CRUD operations using Infragistics Web Data Grid control in ASP. This code is written using Infragistics version 12.2 Create a simple Web Data Grid.This grid has one drop down editor and others fields are text box editors. The grid control has 6 CRUD events associated with it.
If a practical solutions is availble using these properties it will suite my cause better. hence I am looking for an answer to be able to use these properties. The basis of the app is a simple data capture station.
When I open the form, I open the database table too.
However, when I insert a new record (Insert mode activated on open) and press escape on the field, the oldvalue does not contain nil (empty) but the value of the first record of my table.
Like it or not still 2D tables are one of the most comfortable user interface elements in not only viewing data but also in performing rapid inserts and updates.
CRUD operations of Data Grid is not a big innovation, but there are plenty of ways to do that.
