推荐答案

首先，您需要将按钮"visiblity"属性值设置为"false".然后，以下代码将为您提供帮助

First you need to set the button ''visiblity'' property value to ''false''. Then following code will help you

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
       {
           if (CheckBox1.Checked)
               Button1.Visible = true;
           else
               Button1.Visible = false;
       }

您需要修改属性Button.Enabled
