Question

I’m a web designer so I rarely get my hands dirty in .NET code. I’m doing a bit of light coding repurposing some code from one area of a site for another. How to target elements in a master? I have the following in a page that is calling a master that contains lblError and pnlError…

    public void AddError(string error)
    {
        if (error != "")
        {
            lblError.Text = error;
            pnlError.Visible = true;
        }
    }

I’m getting an error that says the items do not exist in the current context. How to I tell it to look for the elements within the master?

So I don’t know if it is the cleanest way to do it, but the following worked for me…

   public void AddError(string error)
    {
        if (error != "")
        {
            Label mpLabel = (Label)Page.Master.FindControl("lblError");
            mpLabel.Text = error;

            Panel mpPanel = (Panel)Page.Master.FindControl("pnlError");
            mpPanel.Visible = true;
        }
    }
