getBindingInfo - how to avoid it?

Posted on Aug 15, 2016 at 03:00 PM 433 Views

Hi guys,

I have an app with an XML view and controller.

What I need to do basically is to put a table on the view, and items with binding - however the binding filter should be dynamic.

So right now I'm having a workaround, which I have a feeling is not so great.

Is there a better way to do this than what I did?

In the controller, I can't get the table's binding, but only the binding info which I think is not recommended to use.

What I also want to avoid is to first load the data without the filter, and then put the filter.

This is what the XML view looks like:

...

<Table

id="table"

items="{

path: '/Rules',

filters: [],

sorter: {

path: 'Name',

descending: false

}

}"

growing="true"

growingScrollToLoad="true"

updateFinished="onUpdateFinished">

...

and the controller:

...

onInit : function () {

oTable = this.byId("table");

var appId = "Something not static";

var oBinding = oTable.getBindingInfo("items");

oBinding.filters = [new sap.ui.model.Filter("ApplicationId", "EQ", appId)];

...

Thanks,

Or.

    Why don't you move the items declaration from the view to the controller?

      You can use a fragment to declare the table and then use it for the template.

      var oTblFrag = new sap.ui.xmlfragment("com.sap.demo.view.Table", this);

  this._oList.bindAggregation("items", {
   path: "/Collection",
   template: oTblFrag,
   filters: myFilters
  });

    Hi,

    You can do this, SAPUI5 Explored

    there dynamic filter used, check the handleConfirm function in Controller file, Dialog.fragment.xml is for the filter,sorter Pop-up(do check this too)

    One more thing, "In the controller, I can't get the table's binding" Why?

    if you are able to get the table control, I think you should get its binding too.

    Thanks,

    Chandan

      So a filter is predefined and on that data you want dynamic filter?

      So if the Model is Odata, at onInit() read the model with your filter, then use the dynamic filter in a different function(as in my 1st reply).

      Like this- inside onInit() do something like this-

      oModel.read("/your_dataset",

      null,

      ["$filter=your_entity eq 'value'"], // filter it

      false,

      function(oData, oResponse){

      //oData will contain filtered data, bind it with the table

      }

      );

      Now make use of SAPUI5 explored example filter in your own function.

      This should do your job.

      Thanks,

    Or

    you can declare the end point in the table (view) then on the controller event ... onBeforeRendering you can apply the filter you need (dynamically)
