Problem with usercontrol...

dear friends in my application m having a label control on the parent page and not i want to access this from the usercontrol. i want to change the text property of the label. I have used this code but it is returning null.

Label lbl = (Label)this.Parent.Page.FindControl("lblErr");

if (lbl != null)

{

lbl.Text = "This shortname is already in use, please use a different shortname."; lbl.Visible = true;

Are you using masterpages? If yes, then note that masterpage itself comes first in hierarchy as a child control of the page.

Yes sir i am using master page, what do i need to do for accessing the label control.

Is there no way to find that label.

Try something like this:

        ContentPlaceHolder content = (ContentPlaceHolder)Page.Master.FindControl("Content1");
        Label lbl = (Label)content.FindControl("UserControlID").FindControl("Label1");
        if (lbl != null)
        { 
          //do something  
        }
