Client Side Context Usage
For Callout: While working with callouts, you can get context as first parameter of callout function.
For Forms: You can create context object for forms like var ctx=VIS.Env.getCtx();
Use in callout
ctx.getContextAsInt(windowNo, "column name"); // Get integer value of column from context
ctx.setContext(windowNo, ColumnName, Value);
ctx.getContext(ColumnName); // Get value of column from context
Use in Form
ctx.getContext(Key); // Get value of column from context
Use in both Callout and Form
ctx.getAD_Org_ID(); // Get Login Org ID
ctx.getAD_Client_ID(); // Get Login Client ID
ctx.getAD_User_ID(); // Get Login User ID
ctx. setContext("key",value);
OR
VIS.Env.getCtx().setContext("key",value);
Server Side Context Usage
For custom controllers
Ctx vCtx = Session["ctx"] as Ctx;
then use vCtx in model classes.
There are some predefined functions in Context class like;
vCtx.GetAD_User_ID() // return logged in user id
vCtx.GetAD_Role_ID() // return user’s role id
vCtx.GetAD_Org_ID() // Get Login Org ID
vCtx.GetAD_Client_ID() // Get Login Client ID
vCtx.GetContext("Key") // Get Context value according to given key
For example: Need to Get current account schema the use below
vCtx.GetContext("$C_AcctSchema_ID")
Here $C_AcctSchema_ID is key to which value user want to get from context
vCtx.SetContext("Key",value) // Set key and its value in context
For Processes
You can get Context object in process classes from parent class of processes. SvrProcess is parent class for all the processes. You can get context information using GetCtx().
GetCtx().GetAD_User_ID() // return logged in user id
GetCtx().GetAD_Role_ID() // return user’s role id
GetCtx().GetAD_Org_ID() // Get Login Org ID
GetCtx().GetAD_Client_ID() // Get Login Client ID
GetCtx().GetContext("Key") // Get Context value according to given key
GetCtx().SetContext("Key",value) // Set key and its value in context
