To keep tabs on the products (and their prices) ordered by these eighty-nine establishments, you have created an awesome grid utilizing the Dev Express ASPx Grid View. You open you grid and stare at the data wondering how you could possibly send all the information contained in the grid to your new hire. You could waive it over your computer screen, utter a few Latin magic spells that would make Hermione Granger proud, and have all your data magically appear as a listing on a paper on your GM’s desk. That’s where I come in to introduce you to the ASP. data in your grid into either a PDF, an Excel spreadsheet, or into an RTF. Only this time, we will transform the document into and Excel spreadsheet.Then, yesterday, you have a meeting with your newly hired General Manager who tells you that she can get you better products for less money. Unfortunately for you, you are a muggle, which means – no magic wand for you! (Note – if you export grouped data to RTF, be sure to open the resulting file with an editor that fully supports RTF features, including tables, otherwise, the file may appear corrupted.) This way, you can email and share your data. So, filter the data by grouping it by the Product Name and then press Export to XLS.This sample illustrates how to show an error text that is set for a column in the server-side Row Validating event handler within the error frame of the corresponding editor if the editor is placed in the Edit Form Template Container of ASPx Grid View. New Values should populate with the new value that was updated, for the Field Name passed to it. For that, you need to check your datasource and make sure the field name is what you expect it to be.

Let’s say you are a super mogul who happens to own eighty-nine different stores, shops, cafes, and the like. So today your task is to send your GM information about which business buys what and where.

I'm changing the value of the Shale Play field and the Row Validating event is firing as expected. Note that that might be different than, for instance, the name of the column in your database (depending on how your Grid View is populated).

EDIT: Markup: Where "Bind Grid" above is whatever process / method / code you use to bind data to your aspx Grid View. "Shale Play" is not the name of the field in the datasource that's populating your Grid View.

Is it possible to check whether any cell was actually modified in Row Validating event handler. Basically the validation could be done on data lever as well, rather that on UI level.

Probably it's possible to do it comparing all cell values with Grid View Row Validating Event Args. Could you please specify what exactly you would like to do regarding the validation, so that we could suggest you another way of validating the data?

This event occurs whenever cells are selected or the selection is canceled, whether programmatically or by user action.

For example, this event is useful when you want display the sum of the currently selected cells.

I have tested the Row Validated event once again and it is thrown as expected when Rad Grid View loses focus.

I used Q3 2010 SP1 (2010.3.10.1215) version for my tests.

Do you want to know when a feature you care about is added or when a bug fixed?

Explore the Telerik Public Issue Tracking system and vote to affect the priority of the items I wrote a generic Row Validating Method that uses reflection to compare the new values against the old ones.
