Hi,
I'm quite new to RAD controls, so be patient :)
I just started to experiment a bit with the RadGrid. I used the client-side binding by connecting the RadGrid to a WCF webservice. Everything works fine. Now I wanted to add a button column for deleting entries. I'd like to fire a server-side event by implementing the ItemCommand. So the code of my RadGrid looks as follows:

The problem is that the ItemCommand event doesn't get fired unless I enable the "EnablePostBackOnRowClick" property on the ClientSettings. I don't like to do this however since then, every click on the row causes a postback which I don't really like.

Can somebody give me a hint of what I'm doing wrong?

Thx

Hmm..ok.

So basically what you're telling me is that if you want to use ajax-enabled grid with client-side binding you have to do EVERYTHING over the webservice. Fetching data, deleting rows etc.

Just for curiosity. Is there another way for gaining the client-side mechanisms such as asynchronous paging and data fetching (through webservice) and having actions etc. post back just normally to the server as you would expect from a standard ASP.net grid?

But I guess this would lead to problems with the ASP.net postback+Viewstate architecture...having a button that posts back but wasn't there before..

Thx again for your answer.

Update:
Alternatively, do you know how to retrieve the current row without using the OnRowSelected event. Basically if I have a GridTemplateColumn inside my grid (an edit button on each row for instance) like this

The "commandEvent" is a JavaScript function which would then do further actions. Do you know how I can retrieve the client-side "DataItem" of the row on which the button has been pressed?

Thx

The source code snippet removed.

Hi Riddhi,

 I reviewed the setup, and the code looks correct.
If the issue persists, you can open a formal support ticket, and send us a small working project, demonstrating your setup, and showing the unwanted behavior. We will debug it locally, and get back to you with additional information.

Best wishes,
Yavor

requesting you to please remove all the source code elements posted here ASAP.

Thanks,
Riddhi

Can anyone solve my problem regarding issue on event OnItemCommand as it is not firing.
Thanks in Advance

Hi Ali,

We will need additional information on your exact scenario, what the expected behavior is and what the actual issue is.

Providing the markup and the relevant part of your code-behind will also prove helpful.

Looking forward to your reply.

Hello Ali,

I have tested your RadGrid settings with dummy data and when I have attached a handler for the server-side OnItemCommand event, it fires as expected when you click on the button from the template column. Following is the sample that I have tested:

And the code-behind:

If further assistance is needed, please elaborate on the exact issue and when do you expect the OnItemCommand to fire.

Looking forward to your reply.

I have the same issue. But only on IE Edge. When I change my browser in compatibility mode to IE 8,9,10 it fires the item_Command event but when edge is selected it does not. Telerik Please do something and save my life. I have been struggling for it for more than 3 days. Googled alot but all in vain.

Hello Sahib,

I have tested the same example in IE 11 and the event is firing as expected on it too.

Can you please inspect your browser's console and see if there are any JavaScript errors that could prevent the proper work of the control. Furthermore, please ensure that you are using version that support IE 11 in the first place.

If the issue persists on your end, please open a regular support ticket and provide a sample, runnable project that replicates the problem, so we can test it locally.

Hi all, although it is old post I can see there are some issues with RadGrid OnItemCommand event not firing in other posts so I'll post mine problem/solution also.

Scenario: Button inside GridButtonColumn with CommandName which when fired does some logic.

Problem: The method that supposed to execute on button event(click) was not executing at all. 

Solution: Change in Page_Load in code behind because there was some logic which was handling what to do when Page.IsPostBack. After "better" defining what to do on postback everything worked as expected.

So, try reviewing where and if you are using Page.IsPostBack and if changing it solves you problems.

Best regards.

 

Yippee Zandi!!! I was having the same issue and in this case it was code in the Page_Init - wrapped that in an if (!IspostBack) and all was well
