Called for each cWebObject during LoadView or LoadWebApp. The event is called before the published (web) properties are serialized.
Can be used to:
- Modify an object's published properties as a view is being loaded,
- Call client actions to be executed after the view/webapp is loaded,
- Set web properties as the view/webapp is loaded.
Object oCustomerView is a cWebView Object oCustomer_DD is a Customer_DataDictionary End_Object Set Main_DD to oCustomer_DD Set Server to oCustomer_DD Procedure OnLoad Send Find of oCustomer_DD FIRST_RECORD 1 End_Procedure : End_Object
Normally you would use the Set command to assign a value to a Web Property during OnLoad, since this is where initial values are being set. The use of WebSet is allowed, but only needed if value of the property needs to be sent from the client to the server on the next request.
To illustrate this, if the code below is used in customer.wo and in one browser we log in as 'guest' and in another browser as 'admin' or 'john', we see a '0' or a '1' being displayed in the oStatusDisplayer object when we browse thru the customers. This means there is no difference between the result of WebGet and Get. When you need the value passed from server to client, you would need to use WebSet in the Onload event.
Object oStatusDisplayer is a cWebForm Set piColumnSpan to 4 Set psLabel to 'Status' Procedure OnSetCalculatedValue String ByRef sValue WebGet pbRender of oCustomerCustomer_Number to sValue End_Procedure End_Object Object oCustomerCustomer_Number is a cWebForm Entry_Item Customer.Customer_Number Set piColumnSpan to 4 Set piColumnIndex to 0 Set psLabel to "Customer Num:" Set peLabelAlign to alignRight Procedure OnLoad Integer iUserRights Get piUserRights of ghoWebSessionManager to iUserRights Set pbRender to (iUserRights<>0) End_Procedure End_Object
Use OnShow as a hook for things like navigation changes.See Also
