    1. Understanding:
      1. In the code for the Image Gallery Demo using RadListView control, a RadBinaryImage control has been used.
      2. In the aspx page, a "onclick="<%#CreateWindowScript((TiledImages) Container.DataItem) %>"/>" event has been used.
      3. Also, if we run the program in debug mode and place a break point on the "CreateWindowScript" method defined in the code behind, we will see that this method is getting called at "Page_Load" itself.
      4. What i understand is its trying to register a Java Script for the click event when ever it occurs.
    2. Requirement:
      1. The images to be shown are stored in the data base.
      2. My requirement is that once the page is loaded and the user clicks on any of the image, I want to call a server side (code behind) method.
      3. Based on the selected Image and its ID, I want to load few other controls with data from the data base.
      4. As far as I understand, the onclick event used in the demo will not serve the purpose.
      5. What other option can I look out for for the above mentioned requirement?
      6. Note: In our project, we plan to use this image gallery in a form of a Live Tile in a ASP.NET application. And hence the usage of ListView and RadBinaryImage control.

    A quick input towards the solution will be very helpful.

    Hello Abhijit,

    Here is a possible approach that you could take for this scenario:

    You can see a RadListView showing RadBinaryImages populated from DB here:

    For raising a server event on clicking an image, you could use the onclick client event handler to raise an ajax callback, through the ajaxRequest client method of RadAjax:
    You can pass the ID as an argument of this method, so in the server AjaxRequest event you can access it from e.Argument.

    Kind regards,
