In the right hand corner you can see there is a extra layer of max, min and close options. I have already disabled control box in child form but I am still getting this.

根据您的描述，您要删除孩子的控制盒层

表格。

您可以尝试以下代码来解决此问题。

子表格代码：

  private void Demo_Load(object sender, EventArgs e)
        {
            ControlBox = false;
        }
