Hide child grid when adding new main item - kendo-ui

I have a grid that has child grid for each item, when i add a new item to the main grid, there is a stub for the child (with the toolbar etc and an empty grid for the child), I would like to hide the child grid when adding new one, i know i need the edit event, i just dont know how to get reference to the detailgrid for the item that the row was just created for input.
edit event has e.sender, e.container, e.model, first 2 reference the main grid of course as the event is raised by the main grid

The required behavior is not supported out of the box, however you can for example attach click event handler to the expanding arrows in the Grid. In the event handler you can prevent the expanding if current model is new. Please check the example below:
//Change Employees with your grid name
//the grid should have model ID defined
$("#Employees table").on("click", ".k-hierarchy-cell a", function (e) {
dataItem = $("#Employees").data("kendoGrid").dataItem($(e.srcElement).closest("tr"));
//check if is new record
if (dataItem.isNew()) {
e.preventDefault();
e.stopImmediatePropagation();
}
})
UPDATE (as requested): The above code should be executed in script tag (wrapped in document "ready" event handler) which is placed just after the Grid initialization code.

Access the child (Button) of a prefab and add function OnClick to it. Unity

I have a prefab which contains some buttons and I want to get the buttons and add specific onClick functions to them via script. I cant find the right way to get the buttons.
What I am trying is:
tempGo = Instantiate(prefabs[0]);
tempGo.transform.SetParent(transform, false);
tempGo.transform.localScale = Vector3.one;
tempGo.transform.localPosition = Vector3.zero;
Transform t = tempGo.GetComponentInChildren<Transform>().Find("AddGoals");
"AddGoals" Is my Buttons(Tag name)
So after this point how can I code it to add a specific function when the button gets clicked?
Any help would be appreciated thank you!
Get button component and add listener to it. Listener will call the function when that button is clicked. TaskOnClick is an example function that will be called when the button is clicked.
t.GetComponent<Button>().onClick.AddListener(TaskOnClick);
void TaskOnClick()
{
Debug.Log("You have clicked the button!");
}
Using .Find(""), you are looking for a gameobject with that name, not its tag. What you can do is after instantiating the object, use GameObject.FindGameObjectsWithTag("AddGoals"). This will return an array of all of the objects with that tag. Then with Linq you can do something like:
var items = GameObject.FindGameObjectsWithTag("AddGoals"); //This gives gameobject array
var itemTansforms = items.Select(x=>x.transfrom).ToList(); //gives you a list of the object tansforms
As for adding an event, you would need to grab the button component of the object and then add the onclick event.
items.ForEach(x=>x.GetComponent<Button>().AddListener(delegate {Debug.Log($"{x.name} has been clicked")}));
You would have to make sure it is actually a button, or the code will fail. This of course can be modified and is just an example. I hope this helps!

Kendo UI MVVM - Changing Model not firing DataSource change event

I have a Grid bound to a DataSource via MVVM.
I select a row in the Grid, accordingly I use this:
var grid = e.sender;
var rowSelected = grid.dataItem(grid.select());
this.set("currentAccount", rowSelected);
Where "currentAccount" holds the currently selected row. Also, "currentAccount" is bound to a Form to be edited by user.
Now, when I do changes on the form fields, they are not being automatically reflected on Grid. I need to call grid.refresh() for the changes to show on grid. With further debugging, I noticed that the datasource defined inside the viewmodel and that is used for Grid, is not firing it's Change event!
However, when user presses a button "Add new record", the following is used to create a new empty model inside the datasource, setting this new model returned by .add() function to be the "currentAccount":
var newRow = this.get("accRegDatasource").add( this._makeAccountModel( 0 ) );
this.set("currentAccount", newRow);
var row = input_map.grid().find(" tr[data-uid='" + newRow.uid + "']");
input_map.kendoGrid().select(row);
Above, I am adding a new empty row. Once I start editing the Form fields, automatically they are being reflected on the Grid without having to call grid.refresh. Even the datasource defined in the viewmodel is firing it's change event.
Any idea why this behavior?
Thanks

Set title and additional properties to kendo ui grid

I am using kendo ui grid to display data. I want to set title for the grid.Is there any way to set it.
Also I want to set some additional/custom property for grid which will help to identify the grid uniquely. Any custom property I can set to grid so I can get its value when required.
So in case if there are more instances on grid this will help.
Please suggest on this.
Iterating through all your tables can be done using:
$.each($(".k-grid"), function (idx, grid) {
// Do whatever you want to do with "grid"
...
});
If you want to add a title, might be something like:
$.each($(".k-grid"), function (idx, grid) {
$(grid).data("kendoGrid").wrapper.prepend('<div class="k-grid-header"><table><thead><tr><th class="k-header">Title</th></tr></thead></table></div>');
});
For setting a click event to the HTML img elements, you can do:
$("tr", ".k-grid").on("click", "img:first", function () {
// Here "this" is the "img" on which you clicked, finding the grid is:
var grid = $(this).closest(".k-grid").data("kendoGrid");
console.log("grid", grid);
// If you want to access the "id"
console.log("id", grid.element.attr("id"));
});
Once you click on the first image of each row what I do in the event handler is finding the closest HTML element with k-grid class (the grid): this is the HTML containing the grid.
If you want to get Kendo UI grid element the you need to use data("kendoGrid").
Simple and elegant.
In this JSFiddle: http://jsfiddle.net/OnaBai/2qpT3/2/, if you click on "Add Titles" button you add a title to each table and if you click on "Add Handlers" and then in an image, you will get an alert with the id of the table that the image belongs to.
EDIT: If you want to iterate on every image that is in the first column, of every KendoUI grid on your document, you should do:
$.each($("td:first > img", ".k-grid table tbody > tr"), function (idx, elem) {
// "elem" is the image
console.log(idx, elem);
// associate event
$(elem).on("click", fnHandler);
});
I prefer to change the title like this:
$("#grid th[data-field=Field]").html("Title");

How can you determine if KendoUI Grid is in a grouped state?

I need to perform an action on my page when the KendoUI grid has been collapsed. I know that the dataBound event fires when the grid is grouped however this event is fired when the grid loads or gets sorted as well. Within my onDataBound event handler how can I tell if the grid is in a grouped state or not.
On DataBound event you can check if the grid currently is grouped using the DataSource group method:
function onDataBound(e) {
gridDataSource = e.sender.dataSource;
if (gridDataSource.group().length > 0) {
//the grid is grouped
debugger;
}
}
To get notified when a group is collapsed you can use delegate event such as:
$('#gridName tbody').on('click','.k-i-collapse',function(){
console.log('Group collapsed!')
})

click on a empty jqgrid

Can anyone please tell how to get the click event of an empty grid.
i have an empty grid, and after inserting i need to refresh the grid for that i use a right click menu in the grid.
So at first there will be no data and need a click event of the grid,
Thanks,
Devan
It seems to me that you should trigger 'reloadGrid' after the filling of the grid.
If you do need implement 'click' or 'right click' event handler to the whole grid and not only the grid body you can use gbox div which will be constructed by jqGrid and which includes all jqGrid elements (see here for details):
var myGrid = $("#list");
// ...
$('#gbox_'+myGrid[0].id).click(function(e) {
alert("click!");
}).bind('contextmenu', function(e) {
alert("right click!");
});
See the corresponding demo here.
