Hi,
I presume you want to make a CheckBox checked based on a value from database, then, you can use something like this:

ASP.NET

<asp:checkbox checked="<%# MakeChecked(Eval("FieldName")) %>" ...="" xmlns:asp="#unknown" />

Then in your code behind:

C#

public bool MakeChecked(object fieldValue)
{
   //Some code to evaluate fieldValue
   //and then based on that return true/false
}

Cheers
