Hi Timo,

In OpenUI5, you can uncheck a CheckBox like this:
var oCheckbox = sap.ui.getCore().byId("Screen1--checkbox"); //insert the screen name and the id of your checkbox
oCheckbox.setSelected(false);
If all CheckBoxes that you want to uncheck are wrapped in a container, e.g. Grid or FlexBox, you can first retrieve all CheckBoxes in the container, then uncheck them in a loop:
var oContainer = sap.ui.getCore().byId("Screen1--grid"); //insert your container's id here
var aContainerContent = oContainer.getContent(); //get all controls in the container. if you use a FlexBox, you can retrieve the items by using 'oContainer.getItems()'
aContainerContent.forEach(function(oControl){
if (oControl.getSelected){ //check if the current control has the method 'getSelected'. You don't have to do this if you only have CheckBoxes in your container
oControl.setSelected(false);
}
});
If your CheckBoxes are all on the same page, you can also use this method:
$('#Checkboxes--CheckboxesPage .sapMCb').each(function(){ //insert your page's id in the selector. 'sapMCb' is the UI5 class for CheckBoxes
var oCheckBox = sap.ui.getCore().byId(this.id); //get UI5 object
if (typeof oCheckBox !== 'undefined'){
oCheckBox.setSelected(false);
}
});
I hope this helps!
