3. RepeaterQuickAction

We can enable or disable the repeating property of the external form by using this rule, instead of designer.
Step 1: Enter the rule as per the below mentioned syntax and append a trigger to it.
Syntax: RepeaterEnableQuickAction(ExternalFormName,True/False)

Step 2: If enable quick action is true then the actions, repeat/ remove/ change view should perform and if the enable quick action is false then none of the quick menu actions should take place. Here , if the check box of the ‘Repeat Property’ is clicked in the designer, then the condition in the rule is set as false and if the same check box is unchecked, then the condition is set as ‘true’ and it is triggered using the buttons , ‘RepeaterDisableQuickAction’ and ‘Enable’ respectively.

a)Action : This rule specifies which is the current action that occurred in the external form
b)RepeatCount : This rule specifies the total number of times the form has being loaded.
c)ViewName : This rule specifies the name of the current view that is shown in the form.
In the Preview, click on the arrow symbol and click the action ‘Repeat’ and thus the rule get executed in the formload as per the below given Figures.
Similarly when the action ‘Remove’ is clicked, the same rule gets executed in the below displayed format.
For the Actions, Repeat and Remove, the trigger is performed ‘First’ and the action (Repeat/Remove) is performed as the next second step. Whereas when View Change is done, the action i.e. the change in the view (form that is selected) is performed as the first step and the trigger is performed as the second step.
