How to access a UserControl in a Master apge from a content page

[Paul]

I have a MasterPage that has on it several UserControls (*ascx files). I
wish to control the visibility of the controls on the content pages
according to some parameter (for example on a user control that depends on a
param StoreID, for the UserControl to be visible only if StoreID is in the
query string.)
How can I access a UserControl in a MasterPage from a Content page?

I tried this, and variations thereof, but get errors:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load

Dim StoreID As Integer = Convert.ToInt32(Request.QueryString("StoreId"))

If Not StoreID.ToString Is Nothing Then

'Master.FindControl("ProductsByStoreAndCategoryUC.ascx").Visible = True

Dim myLocalMasterPage As MasterPage = Me.Master

Dim myControl As UserControl =
myLocalMasterPage.FindControl("CategoriesByStoreUC.ascx")

myControl.Visible = True

End If

End Sub

Thank you for any help,

Is "CategoriesByStoreUC.ascx" the id of the user control in the Master page
?
you need to use the id when using FindControl

No, given that the control on the Master page is called
"CategoriesByStoreUC.ascx", how can I access the visibility of this control
from a Content Page, say the StoresPage.aspx?

Thanks

assigning such an Id is not throwing an "'CategoriesByStoreUC.ascx' is not a
valid identifier." errror ??? -- it should !!
Change the id to not use the .ascx and you can say call it
"CategoriesByStoreUC1" and then use the following in your aspx page :

CategoriesByStoreUCaddComments =
(CategoriesByStoreUC)Master.FindControl("'CategoriesByStoreUC1");

assuming your web control type is CategoriesByStoreUC and it should work
