sap.m.Table refresh items

Posted on Jun 20, 2016 at 03:05 AM 1.6k Views

Hi All,

I have created a simple app which has a view with a SearchField and Table. The search field also has liveChange feature and when the function is called, I call my query to backend system using oModel.read().

In the SearchField, the user can type either a material number or material description and as a result of liveChange, data is displayed in the table below the SearchField

When I delete the typed in text, the search results adjust accordingly, and when the searchfield is empty, no data is shown:

Problem: The problem begins when I start typing in the search field again, it appears that the table has lost its items cells structure.

The above view was created in XML.

I have created the same view in JS and it works fine.

Any suggestions? Please ask for more information and I will provide it as required.

Thanks.

    Resolved using the following code:

    onInit: function() {
     var oTab = this.getView().byId("idTblMat");
     oTab.setModel(oJsonModelS);
     oTab.bindItems("/results", this.getView().byId("idColListItem") , null, null);
},


    liveChange

    onSearch : function (oControlEvent) {

     var sPlant = this.getView().byId("idSelPlant");
     var oTab = this.getView().byId("idTblMat");
     
     var sQuery = oControlEvent.getParameter("newValue");
     if (sQuery) {

          oModelS.read("/MaterialSet?$filter=Werks eq '"
          +sPlant.getSelectedKey()+
          "' and Maktg eq '"
          +sQuery+
          "' and Matnr eq '"
          +sQuery+
          "' ",
          null,null,false,function(oData,repsonse){
          oJsonModelS.setData(oData);
          oTab.bindItems("/results", sap.ui.getCore().byId("idColListItem") , null, null);
     });

     } else {
          oJsonModelS.setData();
     }
},

    Hi Aabhas,

    If possible, can you share the code for table filter?

      Hi Sai,

      I guess you are doing it the right way and I am using a different approch.

      Here's what I am doing:

      Controller:

      onInit: function() {
     var oTab = this.getView().byId("idTblMat");
     oTab.bindItems("/results", this.getView().byId("idColListItem") , null, null);
  },

      //liveChange

      onSearch : function (oControlEvent) {


  var sPlant = this.getView().byId("idSelPlant");
  var oTab = this.getView().byId("idTblMat");

  var sQuery = oControlEvent.getParameter("newValue");
  if (sQuery) {
      oModelS.read("/MaterialSet?$filter=Werks eq '"
       +sPlant.getSelectedKey()+
       "' and Maktg eq '"
       +sQuery+
       "' and Matnr eq '"
       +sQuery+
       "' ",
       null,null,false,function(oData,repsonse){
                 oJsonModelS.setData(oData);
                 sap.ui.getCore().setModel(oJsonModelS);
            });

       } else {
            oJsonModelS.setData();
       }

  },

      View:

      ...

      <SearchField id="idSearchMat" showSearchButton="false"
  emphasized="true" enableSuggestions="true"
  placeholder="Please search for a material number or material description here..."
  search="onSearch" liveChange="onChange">
</SearchField>


<Table id="idTblMat" itemPress="onItemPress">
  <columns>
       <Column width="24em">
            <Text text="Material" />
       </Column>
       <Column width="48em">
            <Text text="Description" />
       </Column>
       <Column>
            <Text text="Storage Bin" />
       </Column>
       <Column hAlign="Right">
            <Text text="Available" />
       </Column>
  </columns>
  <items path="/results">
       <ColumnListItem type="Navigation" id="idColListItem">
            <cells>
                 <Label text="{Matnr}"></Label>
                 <Label text="{Maktx}" design="Bold"></Label>
                <Label text="{Lgpbe}"></Label>
                <ObjectNumber number="{Labst}" unit="{Meins}" />
            </cells>
       </ColumnListItem>
  </items>
</Table>

      ...
