Test this if Output Cache is not enabled.

    protected void Page_Load(object sender, EventArgs e)
    {
        var masterPage = Master;
        if (masterPage != null)
        {
            (System.Web.UI.UserControl)masterPage.FindControl("uc1")).Visible = false;
        }
    }

Hello Ramco

Please use below code
```
protected void Page_Load(object sender, EventArgs e)
    {
        var masterPage = Master;
        if (masterPage != null)
        {
            masterPage.FindControl("uc1").Visible = false;
        }
    }
}
```
In case of Output Cache is enable than please refer below link.
