I want to react to a row click; I don't want the checkbox/select things, I just want to know when a particular row was clicked. Where do I put the hook for that?
use afterSelectionChange.
gridOptions.afterSelectionChange = function (rowItem) {
var entity = rowItem.entity;
// CODE
};

I have a kendo grid, in which I have selected filter on one column, I am reloading the grid, I want the same filter to be there when grid reloads.
I am using the below code to reload the grid. It works, but it doesn't show the selected filter item checked. I checked IDR in the filter then reloaded the page, it shows 1 item selected but doesn't show IDR as checked.
function ReloadGrid() {
var grid = $('#gridId').data('kendoGrid');
grid.dataSource.read();
grid.setDataSource(grid.dataSource);
}
Well there is two way to achieve this.
One way is to save filters in database and second one is to use local storage as mentioned in comment.
I prefer second one, using local storage to save filters and load it upon read.
#GaloisGirl is pointing you in right direction.
Check this example again: Persist state
Basic usage of locale storage is to save some data under some name (key,value):
let person = {
name: 'foo',
lastName: 'bar'
};
let save = function (person) {
let personString = JSON.stringify(person);
localStorage.setItem('person', personString);
console.log('Storing person: ', personString);
};
let load = function () {
let personString = localStorage.getItem('person'); // <----string
let person = JSON.parse(personString); // <----object
console.log('Stored person: ', person);
};
let remove = function (name) {
localStorage.removeItem(name);
console.log('Removed from local storage!');
};
save(person);
load();
remove(person.name);
In kendo world you need to save current options state of grid in local storage, you can achieve that by adding button like in example or on the fly with change or with window.onbeforeunload or like in your example beforen reload grid.
You can check saved data under application tab in browsers, eg. chrome:
Hope it helps, gl!
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!
I'm new in angular. We are using UI-grid for data presentation is is possible to customize filter process. I want to customize it in that way, that filtering is peformmed on button click, not on keydown?
This is idea
$scope.search = function (){
$scope.personCardGrid.useExternalFiltering = false; $scope.grid1Api.core.notifyDataChange(uiGridConstants.dataChange.ALL);
$scope.gridApi.core.refresh() $scope.personCardGrid.useExternalFiltering = true;
$scope.grid1Api.core.notifyDataChange(uiGridConstants.dataChange.ALL);
$scope.gridApi.core.refresh() }

You need to define your own headerCellTemplate for the column. In the template, add a input text box and a button too. Then, define a function in the controller and call it using the external scope which will filter the records.
I am building a website using slickgrid and I have these two problems:
I want to select the entire column whenever the user clicks on the column header. I have been able to change the style of the cells as given in this example. I have not been able to figure out how to change the style of the column header
How to get to know when the end of scroll has happened in slickgrid. I am currently doing
$(".slick-viewport").scroll(function () {
if ($(this)[0].scrollHeight - $(this).scrollTop() <= $(this).outerHeight()) {
handle_end_of_scroll()
}
})
But I am dependent on the css class name of the slick grid body and I might have issues if I end up updating slickgrid later to a newer version. I might have to update this part of the code if the implementation of slickgrid changes.
Change the style of a header
You could force an update to a header which would trigger a onHeaderCellRendered event in which you could then change the class on the header. Pretty messy, though.
grid.onHeaderCellRendered.subscribe(function (e, args) {
var headerCell = args.node;
});
grid.updateColumnHeader('columnID');
Check if scrolled to end
Binding to scroll events directly is always bad. You should subscribe the the onViewportChanged event and getViewport method to check if you have reached the end.
grid.onViewportChanged.subscribe(function () {
var lastRow = grid.getViewport().bottom;
if (lastRow >= grid.getDataLength() - 1) {
console.log('at bottom');
}
});
I have a kendo grid with first column as Checkboxes. I want to delete multiple rows using those check boxes. I am able to delete only single row at a time.
I tried adding
.Batch(true)
for the data source and below is my function for delete button outside the grid.
function deleteRule() {
var grid = $("#grid").data("kendoGrid");
grid.select().each(function () {
grid.removeRow($(this));
});
}
Any suggestions please ?
Yo mate,
How exactly do you remove that one row? Why you use the select method?
Basically I would suggest you to create a delete button which executes the logic to delete the selected rows - I guess you are using a tempalte column with a checkbox inside. If you add a class to that checkbox you can easily select all the checkboxes inside of the grid. So lets say the name of the class for the checkbox is cool then you can execute the following logic in the delete button click handler:
function whenYourDeleteButtonIsClicked(){
var grid = $("#grid").data("kendoGrid");
$('.cool:selected').each(function(){
grid.removeRow($(this).closest('tr'));
})
}
I hope you got the idea mate.
Good luck.
Here is what i use
works very well
$('#your-grid-id').data("kendoGrid").select().each(function () {
grid.dataSource.remove(grid.dataItem($(this).closest("tr")));
});
