Hi i am using the greybox- lightbox effect to show details of a basket.

in this lightbox the user can update there basket (removing items etc), the problem i have got is, if the user removes an item, i need to also update the master page behind the lightbox,

 i have tried the below, but this will not work because the master page is not included in the lightbox, is there a way of accessing the master page directly?

Dim BTlbl As Label = Master.FindControl("BTotalLabel")

Hi,

When you should be careful by using findcontrol method, you should use the control's clientid, because if the page reference the master page, the control's clientid is different from its id,

 For instance, the ID for our Label control is ?Label1?, if it is on the master page,the ClientID of the Label is ctl00$Label1( the MasterPage control ID in this form is ctl00).

If the label control is on the content page, the clientid of the label is ctl00$ContentPlaceHolder1$Label1(ContentPlaceHolder1 is the contentplaceholder's id of the master page).

The more you can refer the section of FindControl, JavaScript, and Naming Containers of this greate article: http://www.odetocode.com/Articles/450.aspx

Hope it helps.

 Hi i am still a bit confused with this...

 because i am using a lightbox that calls a different page Details.aspx (this has NO master page), from this page can,  i update the master page that the lightbox was fired from Default.aspx (which includes a masterapage called MainMaster.master)
 

so i need to update the label on the  MainMaster.master from the Default.aspx
