[Solved] OpenerElementID: set more than one control to open a Window

[Martin]

Is it possible to set more than one control on a page to open a single Window, using the OpenerElementID?

Hi Martin,

OpenerElementId property is of type string, and expect the client-side ID of an HTML element, and I guess we cannot add multiple ID to this property. One suggestion would be open the same window by using client code. Checkout the following documentation for more information on opening window from client side.

Hi Martin,

No, it is not possible to assign multiple values to the OpenerElementID property. This property is intended to be used in simple scenarios only and we do not recommend using it in more complex ones, especially when Ajax is involved. In such scenarios it is best to use either the Server-Side API (VisibleOnPageLoad=true) or the Client-Side one. More information on the subject is available in the documentation.

Thanks guys, that's all I needed to know. I would have suited my purpose if I could have assigned multiple controls to the OpenerElementID, but I have done it with the clientside api instead.
