Rowupdating which wasn t who is rocsi dating 2016

One advantage using this approach is that I do have access to the underlying data source item (a Data Row here) and so I can update the value and rebind easily and immediately show the updated value(s).Doesn't it seem very redundant to have to go through all of this just to get at the underlying data item?In Code Behind you have to do a bit of work though if you want to retrieve the proper context from a Data Item.Here's some code that needs to retrieve a Pk of one of the bound items and then perform some work on the data (in this case the business object): This seems like a lot of code to have to write just to retrieve data context.The problem with the button field is that it's very limited in functionality.If you need custom text for the caption you can't do that because databinding expressions are not allowed.

So I'm taking a few minutes - for my own sake - to write this stuff down so I can look it up next time I have a brain fart Using a Button Field you can specify a Command Name which in turn provides the On Row Command event some context as to what type of operation you are dealing with in Code Behind.Approved which would yield True or False only though) and a Data Format String that can in some cases make this work but for a more dynamic scenario as above that still doesn't do the trick.Template Columns and Commands If something more dynamic is required you need to use template fields.The code first has to retrieve the Grid View Row, which is done by retrieving the Command Argument which in this case a row index of the rendered grid view items.Although the Grid View Command Event Args have a Data Item member that member is unfortunately not set with the Data Row as you would maybe expect.
