Is it possible to handle an onClick event on a Smart Table? I have annotated data coming from my backend. When clicking on an entry, I want to navigate to a new view displaying all data associated with the entry I clicked on.
How can I achieve this in SAPUI5? I can get the internal table with getTable in my JavaScript Controller, but how do I proceed?
On sap.m.Table you can add attachItemPress(oData?, fnFunction, oListener?) and fnFunction will be called to handle the item press.
Because you are trying to use a SmartTable, you need to take into account the TableType. This will really determine the means to handle the 'click'.
Check the tableType of your smartTable and then follow the api reference for that table. If the tableType is sap.ui.comp.smarttable.TableType.ResponsiveTable, then the above should work.
For me works attachSelectionChanged(oData?, fnFunction, oListener?) : sap.ui.model.SelectionModel.
And after this I used that help https://stackoverflow.com/a/36913953/6039287 for get row item params.
Works perfect:)

This is the List Report type of Smart Template application
Here I have selected 2nd and 5th row, I also have a button named Send Requests in the section part which is highlighted. If I click this button it calls a javascript controller function which is defined in the extensions of the application. In this js function how can I retrieve the selected rows that are selected?
I have enabled the checkboxes in this page by mentioning this code
"settings": { "gridTable": false, "multiSelect": true } in the manifest.json
As it was recommended by this link https://sapui5.netweaver.ondemand.com/#docs/guide/116b5d82e8c545e2a56e1b51b8b0a9bd.html
I want to know how can I retrieve the rows which got selected?
There is an API that you can use for your use case. It is described here: https://sapui5.netweaver.ondemand.com/#docs/guide/bd2994b69ef542998becbc69ab093f7e.html
Basically, you just need to call the getSelectedContexts method. Unfortunately you will not be able to really get the items themselves, only the binding contexts (which point to the data entities which are selected). Excerpt from the documentation:
After you have defined a view extension, you can access and modify the
properties of all UI elements defined within these extensions (for
example, change the visibility). However, you cannot access any UI
elements that are not defined within your view extensions.
In this type of table there is way.
var myTable=sap.ui.getCore().byId("your table id");
get all rows:
var myTableRows=myTable.getRows();
now get selected Indices
var selectedIndeices=myTable.getSelectedIndices(); //this will give you array of indeices.
now run loop on indeices array. And get particular row item;
// get binding path
var bindingpath=myTableRows[2].getBindingContext().sPath; // this will return eg:"/ProductCollection/2"
// now get Binding object of that particular row.
var myData=myTableRows[2].getModel().getObject(bindingpath); // this will return binding object at that perticular row.
// once your loop is over in the end you will have all object of selected row. then do whatever you want to do.
If you use smart template create an extension.
This is the standard event befor the table is rebinding:
onBeforeRebindTableExtension: function (oEvent) {
this._table = oEvent.getSource().getTable();
}
In your action function (or where you want) call the table and get the context :
this._table.getSelectedContexts();
I have sap.ui.table.Table which rows are bound to an JSONModel.
var oListModel = new sap.ui.model.json.JSONModel();
//oTable created here (sap.ui.table.Table)
oTable.setModel(oListModel);
oTable.bindRows("/");
When the table is rendered, i.e. the DOM is created for this table, i need to reference to the DOM to pass the DOM elements (table rows) to a library which will make them draggable.
My problem is: How do i know when the DOM for the table is created after the model has been changed and the table is rerendered? I didnt find any listener. The view controller's listener onAfterRendering() didn't help me.
The model is filled with data after a XMLHTTPRequest is successful. When i set the model in the success handler of the xht request and try to access the DOM elments directly afterwards they don't exist yet.
Thank you for your help!
You can add an event delegate
var oMyTable = new sap.ui.table.Table();
oMyTable.addEventDelegate({
onAfterRendering: function() {
$table = this.getDomRef() ....
}
});
a better way is to extend the control see Using addDelegate to extend a control to use third party functionality
UPDATE
the example in that blog doesn't work anymore fixed here
I had a similar issue recently where i had to access an element after a smartform (where the element is present) rendered onto the view. I posted my query here as well as my final solution (based on the accepted answer of #Dopedev). I am using XML views - including nested XML views - here however and the onAfterRendering didn't help for me as well.
I guess you could look at this solution - like it's mentioned in the accepted answer, it may not be an optimal solution, but it sure works. In my case there is not much of a performance issue with the binding of the DOMNodeInserted since it is being called in the onAfterRendering of the nested view that consists of only the smartform with an immediate unbinding upon finding.
The condition if (id === "yourtableid") { } should be enough to identify and pass on. Since you have a table and thus several child nodes, unbinding is imperative at this point.
Mutation Observer is the preferred method but i guess you may need to check the browser compatibility table at the end of the page to see if it matches your requirements. There is an example here. I have used Mutation Observer (outside of a SAPUI5/openUI5 environment) earlier and found it very convenient(and performant) to listen to DOM insert events. In fact the sap.ui.dt package consists of MutationObserver.js
In my Controller doInit(), I create a JSON model and bind it to View
In my View, I use the created model in aggregation binding ( of IconTabBar)
My question is how do I access IconTabBar items in doInit() of Controller. Which event shall I use?
Thanks much.
Check the following example from SAPUI5 Explored:
https://sapui5.hana.ondemand.com/sdk/explored.html#/sample/sap.m.sample.IconTabBar/code
As you can see in the file IconTabBar.view.xml you can set keys for every IconTabFilter. This key should be filled by your binding.
In the IconTabBar.controller.js the handler for the IconTabBarSelect event is implemented. Just read the selected key and act accordingly.
If that does not answer your question, you could post some code examples to clarify your problem.
I have a window with a search form at the top and grid at the bottom.
User can enter values in the search form and click button - Get Records.
At the click of this button, I load the store of the grid by passing the values in form fields as parameters in following way:
store.load({
params:{
key1:Ext.getCmp('field1').getValue();
}
});
I tried giving parameters in the store proxy itself, but it unfortunately always takes up initial values (values when the form is rendered) and not the latest one entered by the users in the form fields. Following is the method I used for assigning values to params while creating the store:
extraParams:{
key1:Ext.getCmp('field1').getValue();
}
I wanted to seek guidance at two things:
a. While defining a store, can I ensure that store takes latest/current values from the form fields before querying server, so that I don't have to provide these values while calling load function?
This becomes more necessary as I have a paging toolbar at the bottom which carries a refresh button (along with next, last, previous, first icons for navigation).
Now, whenever user clicks at refresh (or any navigation icon), the store gets loaded without the query parameters.
Thus the second thing is:
b. If the answer of 'a' is that - Pass the latest values to parameters manually when calling load function - then how can I write the handler for 'refresh' button and navigation icons (that is, next, last, previous and first) in the paging toolbar, so that I can pass the latest form values to load function.
Thanks for any help in advance.
PS: I am using ExtJS 4.
yourStore.on('beforeload',function(store, operation,eOpts){
operation.params={
status:cmbStatus.getValue(),
value:txtBuscarPor.getValue(),
empresa:'saasd',
app:'dsads'
};
},this);
Related to your question (b) (and because you especially asked for this in the comments section):
I see only one standard way to hook into the PagingToolbar button handlers which is very limited.
Ext.toolbar.Paging fires a 'beforechange' event before it actually changes the current page. See API docs. A listener that returns false will stop the page change.
All other methods require extending Ext classes which wouldn't be a problem if the ComboBox would make it easier to use your own implementation of BoundList (which is the class that renders the dropdown) or pass through config parameters to BoundList resp. the paging toolbar.
I tried to bring this lack of flexibility up on the Ext message board once but was pretty much ignored.
A possible solution for this is to use 'beforeload' event of the store and provide the list of parameters in it. This way, whenever the store is loaded, then its beforeload event is fired and the values picked up are always the latest. Hope this helps someone looking for something similar.
I have a two Symfony forms:
ShoppingListForm
ShoppingListItemForm
I'm embedding the ShoppingListItemForm inside the ShoppingListForm many times. i.e. A shopping list contains many items.
So the ShoppingListItemForm consists of two widgets:
item_id (checkbox)
shopping_list_id (hidden - foreign key)
What I would like to do is delete the corresponding ShoppingListItem object if the object exists and the checkbox is left unchecked.
I'm not sure how this delete would occur? Would I use a post validator to see which fields have/haven't been checked? I'm a bit lost on this one.
I'd do this by over-riding the ShoppingListForm's updateObject method and putting your custom delete() etc calls in there (be sure to call parent::updateObject() within it).
Depending how you implement it, you may also need to remove the embedded forms and their values to ensure saving still works correctly for the remaining objects. Try without, but if you do, you need to clear the following:
unset($taintedValues['ShoppingListItem'][$key]);
unset($this->embeddedForms['ShoppingListItem'][$key]);
unset($this->validatorSchema['ShoppingListItem'][$key]);
unset($taintedFiles['ShoppingListItem'][$key]);
If you want to see a custom updateObject method to get an idea how to interact with values etc:
http://www.symfony-project.org/forms/1_2/en/11-Doctrine-Integration#chapter_11_sub_customizing_the_updateobject_method
personnally, I would loop through the existing list items to see whether the corresponding checkboxes are checked in the action, and call the delete() method on the items for which it is not the case. I don't think it is the purpose of a post validator, I would do this directly in the action.
