ASPxPopupControl allows you to specify several web controls or HTML elements whose specific mouse action (defined via the PopupAction property) invokes a popup window. The list of invoker element IDs, which are separated by a semicolon (;), can be set from the PopupElementID property.
Using the ASPxPopupControl client-side functionality, you can perform the following actions with invoker elements.
- Specify elements that invoke a popup window.
- Get the current invoker element.
- Show a popup window for a specified element in a list.
In this demo, ASPxPopupControl is linked to four elements – images. When you hover over an image, the client-side PopUp event is invoked. In the event handler, the popup control gets the current invoker element via the client-side GetCurrentPopupElement method, and displays the corresponding large image as window content.
You can also try this functionality in the ASPxPopupControl - How to define multiple invoker elements on the client to implement image zooming for a set of images example.
