    Hi,

    I have a radgrid and it has 2 column. last coumn is template column which has radrating control. I can use and rate when i open first time to the grid. Then I change to page and on second page I can't rate my rate control. And I is not showing selecting animation. 

    I attached my source codes and screen shots. Please let me know how can I fix it. This project publised and this bug waiting for fix :(

    ps: I check javascript errors on google chorme, Problem is not javascript. I saw no error in javascript.

    Thanks..

    Hello Gökhan,

    I tried to reproduce the problem using the sample code you provided, but to no avail. Note that I had to remove parts of the code as it was not possible to run the page without your data source. You can find attached the my test sample. Please compare it with your actual project and let me know what I am missing.

    I would suggest checking if somewhere in your code the RadRating property ReadOnly is set to true. Also, you can verify if the problem persists when the RadGrid is not Ajaxified or if you have a JavaScript code on the page that could be altering the default behavior of the rating control.

    The online demo RadRating in RadGrid implements functionality similar to yours and it could be used as a reference for properly configuring your project. 

    In case you are still having difficulties, please try modifying the attached sample so that the problem is reproducible and describe the changes that you made. This will allow me to inspect the issue on my end and to provide a more to the point answer. A live URL to your page could also be useful for determining the cause of the problem.

    Kind regards,

    Hi Slav,

    I tried to implement your demo on my page. And I bind your simple datasource, But It didnt work. Result was same. 
    Actually I found new situation about this grid. I opened a ticket few weeks ago (http://www.telerik.com/community/forums/aspnet-ajax/grid/cannot-call-method-showfiltermenu-of-null.aspx) . I think this 2 problem point is same. Because this grid full works only when page opened first time. But when page postback ; Rating (NO Action), Filtering(Uncaught TypeError: Cannot call method '_filterNoDelay' of null error), Sorting(WORKING),PAGING(WORKING).


    I could not publish sample page for you, privacy rules.. :( But maybe I can send your personel work e-mail address..

    Thanks,
    Gökhan

    Hi Gökhan,

    It is possible that the two problems are related. Have you tried the approaches Andrey suggested in the linked forum thread and if you have, what was the result?

    Please describe the changes that you made to the sample from my previous response when you implemented it, so that I can reproduce the issue on my end.

    All the best,
    Slav
