I have filled a KendoDropdown with few data.
Now when I give an input in the Kendo textbox and click a button, I should be able to loop through the items in the dropdown to check if the input value is already exist in the Dropdown.
Please any one tell me how can I achieve this in jquery?.
Any sample code?.
Thanks in advance.
$($("#dropDownName").data("kendoDropDownList").dataItems()).each(function () {
if (this.Value == 10) { //use your logic here
//do your stuff
}
});

Using this I can display a menu by right clicking a cell:
// right click context menu
grid.onContextMenu.subscribe(function (e) {
e.preventDefault();
var cell = grid.getCellFromEvent(e);
//grid.setSelectedRows(cell.row);
$("#contextMenu")
.data("row", cell.row)
.css("top", e.pageY)
.css("left", e.pageX)
.show();
$("body").one("click", function () {
$("#contextMenu").hide();
});
});
However I would like the row to be selected, both as visual confirmation that the correct row has been right-clicked, and because some of the menu items use the selected row for their functions.
This:
grid.setSelectedRows(cell.row);
doesn't work. What is the correct way?
It might be as simple as the fact that setSelectedRows takes an array of row indexes.
Try
grid.setSelectedRows([cell.row]);
I have a kendo grid with filterable = true, mode=row.
I would like a way to have a button click, fire an event that will toggle hiding and showing the filter row.
Right now, I have it working by editing the innerHTML, but this is not what I want to do in the end, for several reasons.
1) I need to have a saved version of the filter row values before they are removed.
2) After they are removed and re-added they will not work
...
many other reasons, just bad practice and there has to be a better way.
A button that fires the event: toggleFilterClick:
<script type="text/x-kendo-template" id="gridFilter">
<button type="button" class="k-button" id="kendoFilterButton" data-click="toggleFilter"><span class="k-icon k-i-funnel"></span>Filter On/Off</button>
</script>
The Javascript code:
//Gets the innerHTML values before they are removed
var filterRowValues = $(".k-filter-row")[0].innerHTML;
//fired when the button is clicked
var toggleFilterClick = $('#kendoFilterButton').on("click", function () {
if ($(".k-filter-row")[0].innerHTML == '')
{
$(".k-filter-row")[0].innerHTML = filterRowValues;
}
else
{
$(".k-filter-row")[0].innerHTML = '';
}
});
Any thoughts suggestions would be appreciated/
I would just like to hide the actual filter row in the header
I'm not sure if i get the point but if you just want to hide it just simply remove everything except$(".k-filter-row").show(); and $(".k-filter-row").hide();. I create an example where when i hide the filter, the filter condtion will removed, but when it showed again the grid will refiltered with the previous value used to filter
$("#toggle").kendoButton({
click:function(){
if($(".k-filter-row").css("display") == "none"){
$(".k-filter-row").show();
//show again filter and execute previous filter condition
$("#grid").data("kendoGrid").dataSource.filter({field:"ShipName",operator:"contains",value:vm.get("filterOptions.ShipName").toString()});
$("#grid").data("kendoGrid").dataSource.filter({field:"OrderID",operator:"eq",value:vm.get("filterOptions.OrderID")});
}else{
//store the previous filter value
//autocomplete
vm.set("filterOptions.ShipName",$("input[data-role='autocomplete']").data("kendoAutoComplete").value());
vm.set("filterOptions.OrderID",$("input[data-role='numerictextbox']").data("kendoNumericTextBox").value());
//hide filter row
$(".k-filter-row").show();
//to reset filter of the grid when filterable hidden
$("#grid").data("kendoGrid").dataSource.filter({});
}
}
});
See the details in action
DEMO
Have you tried just hiding the row instead of removing it?
//fired when the button is clicked
var toggleFilterClick = $('#kendoFilterButton').on("click", function () {
if ($(".k-filter-row").is(":visible")){
$(".k-filter-row").hide();
}
else{
$(".k-filter-row").show();
}
});
So I have a grid and the columns have the good ol' column menu on them with the filtering/sorting/excluding of columns and it all works fine.
The fly in the ointment is that I would like to allow the user to rename a column heading and the obvious place in the UI to allow this is in said column menu.
Something like this:
(where the red bit is just another option that I click on and popup a little window to let me type in a new heading)
Is this possible and how would I do it?
I see that menus can be customized and the grid demo shows how to adjust the stuff in the filter popup but I am not sure how I would add this item (I can see how I would programmatically do the rename but just this getting an option onto the menu has me stumped).
You can use the columnMenuInit event. Two possibilities:
$("#grid").kendoGrid({
dataSource: dataSource,
columnMenu: true,
columnMenuInit: function (e) {
var menu = e.container.find(".k-menu").data("kendoMenu");
var field = e.field;
// Option 1: use the kendoMenu API ...
menu.append({
text: "Rename"
});
// Option 2: or create custom html and append manually ..
var itemHtml = '<li id="my-id" class="k-item k-state-default" role="menuitem">' +
'<span class="k-link"><b>Manual entry</b></span></li>';
$(e.container).find("ul").append(itemHtml);
// add an event handler
menu.bind("select", function (e) {
var menuText = $(e.item).text();
if (menuText == "Rename") {
console.log("Rename for", field);
} else if (menuText === "Manual entry") {
console.log("Manual entry for", field);
}
});
}
})

I guess that the point of a filter is to filter, not to make changes on the grid.
But anyways i found this Kendo Post that may help you to achieve what you need.
You can also take a look a this one too.
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");
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")));
});
