Source error:


Line 31: </ asp: TemplateField>
Line 32: <asp: TemplateField HeaderText = "is the administrator"> <ItemTemplate>
Line 33: <asp: CheckBox ID = "IsAdminCheck" Enabled = "false" runat = "server" Checked = '<% # (bool) DataBinder.Eval (Container.DataItem, "IsAdmin")%>' />
Line 34: </ ItemTemplate>
Line 35: </ asp: TemplateField>

Add this sentence: Checked = '<% # (bool) DataBinder.Eval (Container.DataItem, "IsAdmin")%>' then the above error appears!

Checked = '<% # (bool) DataBinder.Eval (Container.DataItem, "IsAdmin")%>'
Change to
Checked = '<% # checkAdmin (DataBinder.Eval (Container.DataItem, "IsAdmin"))%>'

Add a function in the background:
public bool checkAdmin (object fg) {
bool returnValue;
try {
    returnValue = Convert.ToBool (fg);
  }
catch (Exception) {
  returnValue = false;
}
return returnValue;
}

The above is wrong, it is Convert.ToBoolean (fg);
