Zen TablesAttributedisableSortheaderhiddenDescriptionIf true, disables sorting this column when the user clicks on the column header. If false,enables sorting. The default is for column sorting to be enabled in each column as long asthe useSnapshot attribute for the containing is set to true.Text specifying the column header.Although you can enter ordinary text for this attribute, it has the underlying data type%ZEN.Datatype.caption. This makes it easy to localize its text into other languages, as longas a language DOMAIN parameter is defined in the Zen page class.The %ZEN.Datatype.captiondata type also enables you to use $$$Text macros when you assign values to the headerproperty from client-side or server-side code.The header value can be a literal string, or it can contain a Zen #()# runtime expression.If true, this column is not be displayed. The default is false.This attribute has the underlying data type %ZEN.Datatype.boolean. It has the value "true" or"false" in XData Contents, 1 or 0 in server-side code, true or false in client-side code.The hidden value can be a literal string, or it can contain a Zen #()# runtime expression.14 Using Zen Components
Table ColumnsAttributeOnDrawCellDescriptionName of a server-side callback method in the Zen page class. This method injects HTMLcontent into cells within the column using &html syntax or WRITE commands. Zen invokesthis method whenever it draws the column, automatically passing it the following parameters:• A pointer to the object.• A string that gives the name of the SQL data column that this is associatedwith.• The seed attribute value from the .The callback must return a %Status data type. The following is a valid method signature:Method DrawYesNo(pTable As %ZEN.Component.tablePane,pName As %String,pSeed As %String) As %StatusTo use the above method as the callback, the developer would setOnDrawCell="DrawYesNo" in the statement:The following OnDrawCell callback method interprets a Boolean value (1 or 0) to displaythe string Yes or No in the column.Method DrawYesNo(pTable As %ZEN.Component.tablePane,pName As %String,pSeed As %String) As %Status{If %query(pName) { Write $$$Text("Yes") }Else { Write $$$Text("No") }Quit $$$OK}To retrieve the data value from the SQL column while inside your OnDrawCell callbackmethod, use the %query function as shown in the code example above. %query is a functionthat takes one argument, a string that identifies the name of the SQL column. The signatureof your OnDrawCell method provides this value automatically in the input parameter pName.Thus, the expression %query(pName) in your method resolves to the value contained inthe SQL column that corresponds to this .The example tests to see if the expression %query(pName) is non-zero. If so, it places theword Yes in the column; otherwise it places the word No in the column.Using the %query function in an OnDrawCell callback method is not the same as using the%query special variable in Zen runtime expressions. For information and examples usingthe %query special variable, with dot syntax, see the sections “Zen Special Variables” and“Zen Runtime Expressions” in the book Developing Zen Applications.seedstyleAllows you to pass some arbitrary value to the OnDrawCell callback.CSS style value to be applied to the cells (HTML elements) within this column. Forexample: "color: red;"The style value can be a literal string, or it can contain a Zen #()# runtime expression.Using Zen Components 15
