Remarks

Use conditions

<Looper>.ModifyLine can be used on a browsing or memory Looper control.
WEBDEV - Browser code This function is not available for the Linear Looper controls. This function is available for Looper controls in browser mode only.
WEBDEV - Server codePHP This function is available for Looper controls in Ajax mode, Looper controls in classic mode and Linear Looper controls.
PHP <Looper>.ModifyLine can only be used in a memory Looper control.

Characteristics of the row

If a value corresponds to the result of a calculation, the numeric expression must be enclosed in brackets. For example:
ZR_CalculationZone.ModifyLine(5, (53+29), (83-21))

Sort

If <Looper>.ModifyLine modifies a sort attribute of the current Looper control, the sort on this attribute will be canceled.

Modifying a Looper control without attributes

To modify a Looper control without attributes, we recommend you directly modify the value of the relevant controls.
For example:
// Modify the value of controls
// in "LOOP_Looper1" for row 23
LOOP_Looper1[23].LastNameControl = "Hobbes"
LOOP_Looper1[23].FirstNameControl = "Samantha"
