#CSLA ERRORPROVIDER CODE#
I think your code is possible only because you use an ORM, it is to said a relation between the properties in the BO and the fields of the database. New (info.MappedPropertyName, info.ColumnSize)) New (info.MappedPropertyName, info.MappedFieldName, info.ColumnSize)) PropertyInfo p = GetType().GetProperty(info.MappedPropertyName) CSLA doesn't currently support dynamic properties, so use special rule if property can't be found ValidationRules.AddRule(CommonRules.StringRequired, info.MappedPropertyName) Add rules for all non-nullable string fields not nullable)įoreach (DataColumnInfo info in ColumnInfoCollection.Columns) Add rules for all string columns for maximum length, and whether required (e.g. You might be able to just use the CSLA rule and skip the above: As you can see, sometimes I have to use the special rule above, and sometimes I can just use the built-in CSLA rule. Here is the code that actually adds the rule definitions in my object's AddBusinessRules. If (!String.IsNullOrEmpty(value) & (value.Length > max))Į.Description = String.Format("Field characters", Internal static bool CustomFieldMaxLength(object target, e)ĭecoratedRuleArgs args = (DecoratedRuleArgs)e
Public CustomFieldMaxLengthRuleArgs(string propertyName, string fieldName, int nMaxLength)
Internal class CustomFieldMaxLengthRuleArgs : It would be easy to change this to reflect directly on the property value and use the MaxLengthRuleArgs directly. It references some things not define here (I'm usign the Wilson ORMapper as a DAL and it provides an IObjectHelper interface for referencing the values of backing fields directly).

Is there a solution to this problem ?ģ) often when we do a, the value we use is the length of a field in the database. Also sometimes the message appears twice. After that, it is not possible this message appear again. net 1.0, there is errors on ErrorProvider : if you put the mouse on the small red icon then the message appear but if you click on this icon or if the mouse stay too long time on it, the message disappears. I wish to replace it by a MessageBox.Īlso I wish, in the UI, the user can't to go to another control until the validation rules are not good on the control (textbox for instance) where the focus is.Ģ) Since. In fact, we will invest in these events to ensure we further improve the value proposition for our institutional and corporate clients around the world.Three questions about validation rules and ErrorProvider :ġ) In a winform, when validation rules are not true, the ErrorProvider appear. We are fully committed to continue to deliver thought-leading, world-class Investor Forums throughout 2020 and beyond. Obvious risks around assemblies of large numbers of people within a small space and travel restrictions put in place over the past week by a large number of our institutional investor clients were important considerations. Given the increasing levels of concern caused by the novel coronavirus, we will cancel this year’s ASEAN Forum which was scheduled to take place in Bangkok from March 11-13.
We look forward to welcoming our clients to this year’s Japan Forum (Tokyo: Grand Hyatt Roppongi Hills, May 19-21 already announced) and India Forum (during Q4 exact dates still tbc). More than ever before, this year’s IF will leverage the large number of deep relationships that CITICS has developed over many years as China’s leading investment bank with corporates across China. We will announce details on this year’s IF in due course. Hosting a large Flagship Investors’ Forum (IF) in the Autumn continues to be a strategic priority for the firm. CITICS / CLSA’s Investor Forums have been a key differentiator for our Equities business for many years and represent the very best that our clients value about our franchise: thought-leadership, market-leading Research and world-class Corporate Access.
