Rowupdating old values null

12 Apr

A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.To cancel the update operation, set the collections, if necessary, before the values are passed to the data source. Get String("Grid View_Unhandled Even t", new object[] { this. Row editing and Row canceling editing working fine; but when I press update after changing the value in textbox, it show the old value not that value that I have change.

Sorry that it took some time to write back - my internet connection was (is) down - I've got to work via mobile...

When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.I have a Grid View control and use old style manual binding with a Data Source property and invoke the Data Bind() method. If you don't use one of the Data Source controls, you are required to handle the Row Updating event. Once enabled, all grid columns can be reordered by drag-and-drop. But - when I have a row with some higher type, for e.g. I'm using Npgsql (2.2.0.0) via Nu Get with Target Framework 4.5 But I also tried the Npgsql download version for and with 2.0 - same issue.
