I want DataKeyValue of the Grid row. I have follwoing code in Javascript to do.

var dataItem = grid.get_dataItems()[Index];
var keyValues = dataItem.getDataKeyValue("XYZId");

HI Jayesh,

Thnaks for reply .
There is no property defined in clientsettings for EnableClientKeyValues. And i have already defined the DataKeyNames and ClientDataKeyNames in MasterTableView.
Any other Suggestions please from Anyone else?

Hi,

                        After creating the grid control ,when i refresh a page , I am getting the error as unable to get a value of property of "propertychange" object is null or undefined like in the attachment file.

Please guide me to solve this issue

Hello,

The issue behind both problems is uninitialized object.

@Jai: This is not even a complete statement - var grid = $find('<%=((RadGrid) It should be something similar to : var grid = $find('<%=RadGrid1.ClientID%>');

@Achuthan: On which object you are trying to access the propertychange property?

I've been searching these Forums for weeks trying to resolve this issue.  This post seems related to my issue.  If I have my RadGrid inside a FormView's Insert/Edit template, the Grid NEVER initializes its JavaScript.  My scenario does not happen during any Post Backs, it's just that the Grid does NOT initialize any of its client-side API when it's inside another container.  Is there anyway around this?

[Tim]

I've also noticed that on the "Add Record" button of the Grid's command buttons, the JavaScript looks like this:

if(!$find('').showInsertItem()) return false;

or more accurately...

onclick="if(!$find('').showInsertItem()) return false;"

Hello,

About your first question, may I ask why you need to place the RadGrid inside FormView control? RadGrid provides built-in functionality to insert/updated/delete records from the datasource. You could check how this is achieved in this online demo application.

About your second question, this was a bug in our older releases which is now fixed. Please upgrade to the latest version and you should not have any problems.

Yes, I have moved the Grid outside the FormView.  The original thought was that it had to be in there because we were editing one parent-record and the grid represented the child data.  But it makes sense to move it out.

Which version was this fixed (2013.1 SP1?), we are using 2013.1.

Hi,

The bug was fixed for Q1 2013 SP1 release. Using the latest version always guarantee that you have latest fixes.
