[CLOSED] add multiple Labels in Codebehind
Hi,
I want add editable labels in codebehind. The count of labels depentds ao search result.
Therfore I must add the Labels in codebehind.
But when I generate the labels in a loop I alway get the error:
Description: An
unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the
error and where it originated in the code.
Exception Details: System.ArgumentException: A
Control with an ID of "False" has already been initialized. Please
ensure that all Controls have a unique id.
The following Control has the same ID as at least one other Control on the Page. All Controls must have a unique ID.
*************************
Control Details
*************************
ID: False.
ClientID: False
Type: Label
*************************
Parent Control Details
*************************
ID: Tab3
ClientID: Tab3
Type: Panel
Thanks for help
