Answer 1

You can convert you int value 1 or 0 and then assign to your check-box checked property. If they are string type then convert them to int and then to Boolean

 CheckBox1.Checked = Convert.ToBoolean(0);  // False - Not checked.
CheckBox1.Checked = Convert.ToBoolean(1);   // True - checked.

You can use this method Convert.ToBoolean(value) to convert string to boolean

CheckBox1.Checked = Convert.ToBoolean("false");  // False - Not checked.
CheckBox1.Checked = Convert.ToBoolean("true");   // True - checked.

Answer 2

You will get either 0 or 1 from database right?? SO, store it in integer variable a;

{
if (a==0)
chkbox1.checked = false
else
chkbox1.checked = true;
}

Answer 3

<asp:checkbox id="Cluster" runat="server" checked='<%# Eval("Cluster") == DBNull.Value ? false : Eval("Cluster") %>' />

Answer 4

您可以使用以下代码从数据库中获取值并将其以Web形式表示：

CheckBox1.Checked = rdr.GetBoolean(3);
