CS Page

Here based on Type, Name values can be bind

public string getValue(object c, object value)

{

List<BusinessRuleType> types = (List<BusinessRuleType>)ViewState["types"];

string typeName = types.Find(item => item.ID == (int)value).Type;

if (typeName == "Input")
{

return DataBinder.Eval(c, "InputValue").ToString();
}

else if (typeName == "Range")

{

return DataBinder.Eval(c, "MinRange").ToString();
}

else if (typeName == "Bool")

{

return DataBinder.Eval(c, "BoolValue").ToString();

}

else if (typeName == "Formula")
{

return DataBinder.Eval(c, "Value").ToString();
}

return "";

}
