Uncollapse Columns by RowClick

I have setup my table in Tabulator with responsiveLayout:"collapse" and responsiveLayoutCollapseStartOpen:false.
My table display properly with collapsed columns.
I added formatter:"responsiveCollapse" as column and I properly get the column with + and - icons and can manually expand/collapse the columns.
But for usability on a smartphone, the icon renders really a bit small.
I want to add to expand/collapse based on callback rowClick.
I found responsiveCollapse and toggleList in tabulator.js, so I think I know what needs to happen. However I am totally struggling how to return it out of rowClick.
Thank you very much for a hint in advance.
In the tabulator constructor I have:
columns:[
{ formatter:"responsiveCollapse", width:30, minWidth:30,
hozAlign:"center", resizable:false, headerSort:false, responsive:0 },
{ title:"Ren.", field:"Race_Number", sorter:"number",
hozAlign:"center", minWidth:60, widthGrow:1, responsive:0 },
]
And basically I want to achieve the some functionality as formatter:"responsiveCollapse" in rowClick:
rowClick:function(e, id, data, row){
//trigger an alert message when the row is clicked
//what to do here to achieve same as formatter:"responsiveCollapse"
},

You could copy some of the code from the built-in responsiveCollapse formatter to achieve this. It will involve accessing some private variables, which is a bit naughty, but it will do the job:
rowClick:function(e, id, data, row){
var config = cell.getRow()._row.modules.responsiveLayout; //get the responsive config object for the row
var collapseEl = config.element; //get the collapsible element for the row
if(collapseEl){ //check if the row has any collapsed data
config.open = !config.open; toggle the open state
//toggle the collapse element
if(config.open){
el.classList.add("open");
collapseEl.style.display = '';
}else{
el.classList.remove("open");
collapseEl.style.display = 'none';
}
}
}

this was very helpful, remember to comment out "toggle the open state" and also update
el.classList.remove("open");
to
collapseEl.classList.remove("open");

Input field in Table "keeps" edited number in same row while scrolling (JSView)

I've got a sap.ui.table.Table with Input fields and the table gets the data via JSON which works well. However, if I edit the value in the first row for example, and try to scroll down, the value "stays" in the first row until a different value hits this field. So it basically updates every cell except the edited one while scrolling. After that, I scroll up again to see the value I changed, but this value now has the old value from the load at the beginning again.
I think something with my binding isn't correct at all, because I haven't seen anything like this yet. I know that tables only update the row contexts but I can't figure out how to do this.
Here is a example: https://jsbin.com/yuvujozide/6/edit?html,console,output
Edit the right "Gates" and scroll, to see how it disappears and edit the left value and scroll to see how the value scrolls with the table.
I tried to remove/set the VisibleRowCount and logged to see if the data gets loaded multiple times but that's not the case.
var oModel = new sap.ui.model.json.JSONModel();
var oTable = new sap.ui.table.Table({
visibleRowCount: 12,
selectionMode: sap.ui.table.SelectionMode.Single,
visibleRowCountMode: sap.ui.table.VisibleRowCountMode.Fixed,
editable: true
});
oModel.setData({ rows: tableRows.value, columns: columnArray });
oTable.setModel(oModel);
var counter = 0;
oTable.bindColumns("/columns", function (sId, oContext) {
var columnName = columnArray[counter];
var defaultTemplate = new sap.m.Input({
value: "{" + columnName + "}"
}).bindProperty("value", columnName, function (cellValue) {
return returnRange(this, oTable, cellValue, columnName, counter, dic);
});
counter++;
return new sap.ui.table.Column({
label: columnName,
template: defaultTemplate,
flexible: true,
autoResizable: true,
width: 'auto',
multiLabels: [
new sap.ui.commons.Label({ text: columnName }),
new sap.ui.commons.Label({ text: dic[Number(counter - 1)].value[0] + " - " + dic[Number(counter - 1)].value[1] })
]
});
});
oTable.bindRows("/rows");
As you can see I separated the rowData and columnNames in two arrays:
tableRows and columnArray
The returnRange function checks some values and just returns the cellValue
I would expect that the Input fields keeps the changed values (which is probably normal), so I can change several Input fields and then I can Update the table via Ajax-Call.

The problem is that sap.ui.table.Table has a custom scrolling behaviour that is different from the default browser scrolling. Instead of creating a row for each record, it will create a fixed number of rows and re-bind these rows after each scroll.
If the table is editable and bound to a JSONModel, it will usually create a two-way-binding and update the model values upon user input, hence scrolling works fine. But since you have provided a custom formatter function for the binding (returnRange), a two-way-binding is not possible anymore. This means that any user input is lost after scrolling.
If you remove the formatter function like this
var defaultTemplate = new sap.m.Input({
value: "{" + columnName + "}"
});
it will work fine.
In case you want to validate the user input, you should listen to the input's change event and use InputBase#setValue to set it to a different value. This will also reflect your changes in the JSONModel.

SAPUI5 TreeTable's getRows method returns empty array on the first call

I am trying to build an SAPUI5 application using TreeTable and I'm facing some problems to use its methods.
In my app, I have a button which triggers this method.
onChangeViewContext: function(oEvent) {
.........
.........
var aViewContext = oContext.oModel.getProperty(sPath + "/ViewContext");
var aDataModel = oContext.oModel.getProperty("/ApplicationCollection/" + sAppId + "/DataModel");
var oStructure = this._createParentChildStructure(aDataModel);
var oTreeModel = this.getView().getModel("treeModel");
oTreeModel.setData(oStructure);
this._oViewDetailLine = oSource.getParent().getParent().getParent();
this._oViewDetailLine.setVisible(false);
this.byId("idSelectElementsPanel").setVisible(true);
this._setSelectedItems(aViewContext, oTree);
}
What I'm trying to do here is only bind the rows with my treeModel, get tree table object and send it to my _setSelectedItems method which below.
_setSelectedItems: function(aViewContext, oTree) {
oTree.clearSelection();
var sElementName;
var aSelectedIndices = [];
var aElements = [];
var aRows = oTree.getRows();
aRows.forEach(function(row) {
if (row._oNodeState !== undefined) {
aElements.push(row.getCells()[0].getText());
}
});
I need to get rows array here because I will use it for setting selected items of tree table. The problem is when "onChangeViewContext" triggered, oTable.getRows() returns an empty array. But when I click cancel button (which just hides my tree table, nothing more) and then trigger "onChangeViewContext" function again, I can get the rows array completely.
Even on the first call when I try to get table's model, I can get the treeModel and its data correctly.
I've tried to refresh bindings, aggregations etc. But no luck.
By the way, I'm using row binding in my xml view like this :
<t:TreeTable id="idSelectElementsTree" rows="{path: 'treeModel>/'}" selectionMode="MultiToggle" enableSelectAll="false"
rowSelectionChange="onSelectElement">
I'm really drowning here so any any help would be appreciated.
Edit : rest of the setSelectedIndexes function :
aViewContext.forEach(function(name) {
sElementName = name;
if (aElements.indexOf(sElementName) !== -1) {
aSelectedIndices.push(aElements.indexOf(sElementName));
}
});
aSelectedIndices.forEach(function(idx) {
if (oTree.getRows()[idx]._bHasChildren) {
oTree.expand(idx);
}
oTree.addSelectionInterval(idx, idx);
});

What could help here is to add an event rowsUpdated="onRowsUpdated" to the table in the XML view. This event is triggered after the table has been loaded and will hence provide you with the data via;
this.getView().byId("sTableId").getRows();
The difference to your approach is that the event would not be triggered by the press of a button but automatically, as the table is rendered. You can then also use this function to trigger another one as per your use case.

Component lost during rerender, how to reattach?

I am rendering a component into a grid rowExpander plugin rowBodyTpl:
plugins: [{
ptype: 'rowexpander',
rowBodyTpl : [
'<div id="contact-row-{Id}"> </div>'
]
}],
var row = 'contact-row-' + record.get('Id'),
grid = Ext.getCmp(gridId),
if(!grid) me.createSubGrid(record,gridId).render(row);
This works fine. But when the grid receives an update event for a record with certain modifiedFields, that record's rowExpander is rerendered using the rowTpl only, and the inner grid is dangling somewhere. I can access the grid using Ext.getCmp, and grid.rendered is true, but it is not shown. So I guess I have to reattach the grid after the row has been rerendered.
I think I can attach to the update event, and find out whether the rowTpl has been rerendered without the child grid using
if(!grid.container.contains(grid.el))
But is there a way to put the grid back into the dom?
I have tried
grid.container.insertFirst(grid.el);
but this does not work. The element is inserted but the grid is not displayed.
Any ideas?

The way you are doing leads to memory leaks (because your component is not destroy when the grid is re-render).
I suggest to check at : Component Template (http://skirtlesden.com/ux/ctemplate) or if you try to render a nested grid, there was several attempt to build something correct and I think a working one is the following : http://blogs.walkingtree.in/2015/06/30/nested-grid-in-sencha-ext-js/

With my trials, I already was on the right track, and the error was somewhere else entirely. The problem was that my update event fn which did the reattach was executed before the update event fn that broke everything, because the fn was fired on the same event and had the same priority, but was attached to the store earlier. Changing the priority was one option, but I just put the creation into the boxready event, which is executed after the view has attached its events to the store:
xtype:'grid',
listeners:{
boxready:function(grid) {
var store = grid.getStore();
...
store.on({
update:function(store, record) {
me.restoreSubgridDom(record);
},
beforeload:function(store) {
var records = store.getRange();
Ext.each(records,me.destroySubgrid);
}
});
}
}
with the two functions:
restoreSubgridDom: function(record) {
var row = 'contact-row-' + record.get('Id'),
gridId = 'ContactRow'+record.get('Id')+'Grid',
grid = Ext.getCmp(gridId);
if(grid && !grid.container.contains(grid.el))
{
grid.container.insertFirst(grid.el);
}
},
destroySubgrid: function(record) {
var gridId = 'ContactRow'+record.get('Id')+'Grid',
grid = Ext.getCmp(gridId);
if(grid) grid.destroy();
}

ng-grid change sorting order onchange of drop down

I am using ng-grid , i have implemented search functionality on it but i want to change orderby option by changing drop down value.
I wish to provide drop down on change of its value data soting should happen.
by default Sort-functionality is there which works on click of table heading but i need to change sorting order on change of dropdown.
This code i got from somewhere but i dont know how to use it ?
$scope.gridOptions = {
data: 'gridData',
columnDefs: [
{field: 'name', displayName: 'Name'},
{field:'ageWord', displayName: 'Age'}
],
sortInfo: {
fields: ['age'],
directions: ['asc']
}
};

You need to define values for the sortInfo and useExternalSorting of your grid options, like this:
$scope.gridOptions.useExternalSorting = true;
$scope.gridOptions.sortInfo = {
fields: [$scope.selectedDropDownOption], // <-- or whatever variable used to store selected option from dropdown
directions: ['asc']
};

e.g.: if you want to sort by name, you could set
sortInfo: { fields: ['name'], directions: ['asc']}
this would order your grid by name and ascending
you also want to set useExternalSorting = true in your gridOptions.
i suggest you have a look at the docu and examples pages

I used following code ,,,
HTML :
<input type="text" ng-model="sortColumn"></input>
<button type="button" class="btn" ng-click="updateSortInfo()">Sort</button>
aap.js ::
$scope.updateSortInfo = function() {
$scope.gridOptions.sortBy($scope.sortColumn);
}

Reached here while searching for solution of similar thing. After trying all options I have applied this.
//Disable Grid Ui Sorting through header
$scope.gridOptions.enableSorting = false;
//Apply angular 'orderBy' filter to data for grid ui
$scope.resultSetTable = $filter('orderBy')($scope.gridData, 'YOUR_SORT_COLUMN');
// Apply data to grid ui
$scope.gridOptions.data = $scope.resultSetTable;
