In February I switched my job, I was a C# developer and now, I`m using SAP UI5 to create new, modern software. My main task in the past was to create or modify some client applications. My current task is, to build a seat reservation tool using UI5.

During my work on the application I learned a lot about the SAPUI5 framework. Now I would like to share my experience with you.

First I would like to give you a short overview of the application.

I have a list of four rooms in my master view at the moment (later it would be a variable amount of rooms) and every room has a detail view with two, three or four seats. Every seat has his own attributes and positions. My current program includes a detail view with an “ObjectList” control, I bind the model at this element as an“ObjectListItems”.  After the event “UpdateFinished” I hide this control.

Why I go this kind of way?

Because I can`t bind my model at the tiles container in the XML view, so I don`t get an actual model. To continue my tiles story, I create a new function in the event (“UpdateFinished”) and draw the tiles. In this function I use the property ODataModel of the model. I collect all valid entries of my selected room and write them in a separate list. At the end I use a loop to create the tiles and fill them with the attributes.

In the detail.view I used an empty AbsoluteLayout as a container.


The controller includes the following function:

 drawTiles: function(oEvent) {   // prepare a list   var activeList = [];   if (localController == null)        localController = this;   // get the local model and transfer all objects in the odata object into the prepared list,   // if the the condition is true   var model = localController.getView().getModel();   $.each(model.oData, function(index, value) {        if (index.indexOf("SeatSet")>-1) {             activeList.push(value);        }   });   // GET IMAGE // var oImageSource = localController.getView().byId("imageBox").getSrc();   var oImageSource = pic;   // save the local items and model from hided list   localItems = localController.getView().byId("lineItemList").getItems();   // sort activeList and convert roomNo (string)   var roomid = ZSeatReservationUI5.util.Formatter.Quantity(roomNo);   activeList = this.sortList(activeList, roomid);   // set ABSOLUTE LAYOUT   var heigth = "800px";   var width = "650px";   var oAbsoluteLayout = localController.getView().byId("AL1");   oAbsoluteLayout.setVisible(true);   oAbsoluteLayout.destroyContent();   oAbsoluteLayout.setHeight(heigth);   oAbsoluteLayout.setWidth(width);   oAbsoluteLayout.addContent(new sap.ui.commons.Image("Background", {src: oImageSource, width: width, heigth: heigth}));   var i = 0;   // loop on prepared list for every item and create for every item in list a new tile   while(activeList.length > i) {        var left = 0;        var top = 0;        var oContext = activeList[i];   // defined positions        switch (i){                  case 0:                          left = 116;                           top = 50;                           break;                  case 1:                            left = 340;                             top = 50;                            break;                  case 2:                            left = 116;                            top = 306;                            break;                  case 3:                            left = 340;                            top = 306;                            break;                  default:                            break;             }   left = left + "px";   top = top + "px";   var oTile = new sap.m.StandardTile();   //Layout: size of tiles   // Height: 226px   // Width: 194px   // set the bindings of the tiles   oTile.setTitle(ZSeatReservationUI5.util.Formatter.List(oContext.Attribute));   oTile.setNumber(ZSeatReservationUI5.util.Formatter.SeatText(oContext.SeatID));   oTile.setIcon(ZSeatReservationUI5.util.Formatter.UserUrl(oContext.UserId));   oTile.setInfo(ZSeatReservationUI5.util.Formatter.StateText(oContext.State));   oTile.setInfoState(ZSeatReservationUI5.util.Formatter.State(oContext.State));   oTile.setNumberUnit(oContext.User);   oTile.attachPress(this.handleSelectDialogPress);   oAbsoluteLayout.addContent(oTile, {left: left, top: top});        i++;   } }, ,,,,,, 

After this, the app looks like:

The tiles includes a press event, that triggers a reservation of the selected seat.

In addition I’m using the following ODATA structure:

I have also tested another way, the use a TileContainer control. The structure is very simple, I have created a container in my detail view.


The controller includes the same function as the first example, except of the loop. I tried to use a template and the “bindAggregation” function of the container.

 var oTileContainer = localController.getView().byId("idTileContainer"); oTileContainer.setModel(model); var oTileTemplate = new sap.m.StandardTile({   title:"{Attribute}",      number: "{path:'SeatID', formatter:'ZSeatReservationUI5.util.Formatter.Quantity'}",      info: "{path: 'State', formatter:'ZSeatReservationUI5.util.Formatter.StateText'}",      icon: "{path: 'UserId', formatter:'ZSeatReservationUI5.util.Formatter.UserUrl'}",      infoState: "{path: 'State', formatter:'ZSeatReservationUI5.util.Formatter.State'}",      numberUnit: "{User}"   }); oTileContainer.bindAggregation("tiles", "/SeatSet", oTileTemplate); oTileTemplate) 

I ask myself the following question, why I couldn’t use the tiles and the tile container like a list control, for example, likes an objectlist with objectlistitems?

I also tried to create a tile container at the XML view . In the following I tried to bind the model, but I only get an empty page. I think the problem is, I didn’t define the aggregation like in a list control. (short example below)


The detail view contains this snippet.


I hope I could give you a little insight into the use of tiles. If there are any suggestions or ideas for  an improvement of my app, bring it on.
