input box not updating when checkbox is selected sapiu5

2.1k Views Asked by eDz At 28 April 2025 at 00:34

I created a table in Web IDE that has a checkbox and input box that by default shows "100%" when checkbox is selected. It was working before I added data from a json but now that I made the column list item a template taking in data from the json on some of the columns, the input box does not fill in when selecting checkbox.

What shows up now:

What I want to show up:

If I use something like message box, it does the correct output when selecting checkbox.

sap.m.MessageBox.alert("100%")
sap.m.MessageBox.alert("0%")

I binded the event to the checkbox under select. This is the code for the checkbox.

    percentCheck: function(oEvent) {
        //inputText is the input Text box  
        var inputText = this.getView().byId("inputPercent");
        var isSelected = oEvent.getParameter("selected");

        if (isSelected) {
            inputText.setValue("100%");
        } else {
            inputText.setValue("");
        }
    }

This is what I was able to use to make it work with data

View:

<CheckBox id="checkEstimate" select="estimatePercentageSelect"/>
<Input value="{percent}" width="100%" id="inputPercent"/>

Controller:

estimatePercentageSelect: function(oEvent) {
//get parameter if checkbox is selected
var isSelected = oEvent.getParameter("selected");
//get source to bind
var cxt = oEvent.getSource().getBindingContext();

//if checkbox is selected, set property "percent" to 100%
if (isSelected) {
  cxt.getModel().setProperty("percent","100%",cxt);
  }
  else{
    cxt.getModel().setProperty("percent",null,cxt);
  }
}

I think that it is better to update the model and not change the value of the control directly. here is an example http://jsbin.com/yuhipop/edit?html,js,output
