Why would you need to validate a label control? It's just there to display text (an do other events, but still). I don't think you can use the validator control to validate static controls like that(image control, label, ect.)
Can you explain a little more about why you need to validate your label?
|
|
|
|
|
why i need to validate label is
i have a calender control(ajax) and textbox(asp.net)
i was performed required field validation on textbox bec it is must and
should for me, and it allow me to edit the textbox date,
but i dont want to edit textbox..
i know the other way to keep this as readonly
finally
i dont want to show the layout of textbox so i need a label
and there must be data in label at runtime i.,e required field it is
|
|
|
|
|
So you have a textbox to edit the date value of your calender control, but you don't want to use the textbox to edit?
There's no way to use a label in they way your trying. Validation controls only work on input controls, which a label is not. Why dont you change the style of the textbox to seem like a label?

hi....
Thank you for helping me..
yah i too got the count but i am getting the count after clicking
the button submit in my page.
I wrote the code in Checkbox1_ChechedChanged.
I took the count into the label.
plz tell me where i am missing...
Thanks in advance
|
|
|
|
|
ya you miss AutoPostBack="True"
if you give AutoPostBack="True" only it will fire the Checkbox1_ChechedChanged event.
