The TemplatePut method / TemplateDef property has been added to allow programming languages such as dBASE Plus to set control's properties with multiple parameters. It is known that programming languages such as dBASE Plus or XBasic from AlphaFive, does not support setting a property with multiple parameters. In other words, these programming languages does not support something like Property(Parameters) = Value, so our controls provide an alternative using the TemplateDef / TemplatePut method. The first call of the TemplateDef should be a declaration such as "Dim a,b" which means the next 2 calls of the TemplateDef defines the variables a and b. The next call should be Template or ExecuteTemplate property which can use the variable a and b being defined previously. 

The TemplateDef, TemplatePut, Template and ExecuteTemplate support x-script language ( Template script of the Exontrols ), like explained bellow:

The Template or x-script is composed by lines of instructions. Instructions are separated by "\n\r" ( newline characters ) or ";" character. The ; character may be available only for newer versions of the components.

An x-script instruction/line can be one of the following:

• Dim list of variables Declares the variables. Multiple variables are separated by commas. ( Sample: Dim h, h1, h2 )
• variable = property( list of arguments ) Assigns the result of the property to a variable. The "variable" is the name of a declared variable. The "property" is the property name of the object in the context. The "list or arguments" may include variables or values separated by commas.  ( Sample: h = InsertItem(0,"New Child") )
• property( list of arguments ) = value Changes the property. The value can be a variable, a string, a number, a boolean value or a RGB value.
• method( list of arguments ) Invokes the method. The "list or arguments" may include variables or values separated by commas.
• { Beginning the object's context. The properties or methods called between { and } are related to the last object returned by the property prior to { declaration.
• } Ending the object's context
• object. property( list of arguments ).property( list of arguments ).... The .(dot) character splits the object from its property. For instance, the Columns.Add("Column1").HeaderBackColor = RGB(255,0,0), adds a new column and changes the column's header back color.

The x-script may uses constant expressions as follow:

• boolean expression with possible values as True or False
• numeric expression may starts with 0x which indicates a hexa decimal representation, else it should starts with digit, or +/- followed by a digit, and . is the decimal separator. Sample: 13 indicates the integer 13, or 12.45 indicates the double expression 12,45  
• date expression is delimited by # character in the format #mm/dd/yyyy hh:mm:ss#. Sample: #31/12/1971# indicates the December 31, 1971
• string expression is delimited by " or ` characters. If using the ` character, please make sure that it is different than ' which allows adding comments inline. Sample: "text" indicates the string text.

Also , the template or x-script code may support general functions as follows:

• Me property indicates the original object.
• RGB(R,G,B) property retrieves an RGB value, where the R, G, B are byte values that indicates the R G B values for the color being specified. For instance, the following code changes the control's background color to red: BackColor = RGB(255,0,0)
• LoadPicture(file) property loads a picture from a file or from BASE64 encoded strings, and returns a Picture object required by the picture properties.
• CreateObject(progID) property creates and retrieves a single uninitialized object of the class associated with a specified program identifier.
