Navigate to specific cell - javascript

I'm using KendoUI Grid to display some data, the grid is pageable and scrollable, right now I'm able to select and scroll to a specific row, but now when I'm there I also should be able to navigate and select a specific cell (td) of that row. This is what I've so far.

var dataSource = grid.dataSource;

if (model[idField] == searchedId) {
modelToSelect = model;
rowNum = i;
break;
}
}
// If you have persistSelection = true and want to clear all existing selections first, uncomment the next line
// grid._selectedIds = {};
// Now go to the page holding the record and select the row
var currentPageSize = grid.dataSource.pageSize();
var pageWithRow = parseInt((rowNum / currentPageSize)) + 1; // pages are one-based
grid.dataSource.page(pageWithRow);
var row = grid.element.find("tr[data-uid='" + modelToSelect.uid + "']");
if (row.length > 0) {
grid.select(row);
// Scroll to the item to ensure it is visible

title: "Units in Stock",
width: 150
}, {
field: "Discontinued",
width: 150
}]
});
});
</script>
</body>
</html>
For example what I want to do is to navigate to row 4 (this is working) but also navigate to column Discontinued and select that cell of that row.
Is there any way to do it? Using JavaScript or jQuery or a native function from KendoUI?
Here is a Dojo to play with.

Add a class to your Discontinued column definition:
{
field: "Discontinued",
width: 150,
attributes: {
class: "discontinued"
}
}
Change the selector you're using to select the row to the following:
var row = grid.element.find("tr[data-uid='" + modelToSelect.uid + "'] td.discontinued");
Replace grid.content.scrollTop(grid.select().position().top); with row[0].scrollIntoView();.

Kendo grid make detailinit expand and checkbox selected when select master table

I create a similar demo relate with my situation. What I want to achieve when checked on the master grid, the details grid will expand and all the checkbox inside it will be checked and also the child grid is selected.
It's possible to do like this without using column template for the checkbox.
DEMO IN DOJO
Example like this screen shot. (this one manually checked)
p/s: I found a similar demo, but this one using column.template for the checkbox.
This example code (which is based on your sample code) answers your requirement, which is...
What I want to achieve when checked on the master grid, the details grid will expand and all the checkbox inside it will be checked and also the child grid is selected.
Try this in the Telerik DOJO. We need to wait for Kendo to finish expanding the detail row (making sure all HTML elements are fully built), hence the setTimeout in detailExpand. Change the delay depending on your needs.

I adapted your first snippet based on the second one that you provided. Check out this revised demo.
Basically, you need to call getKendoGrid() and assign its return value (the actual grid) to the grid variable.
After that, add the change event listener as shown in the second demo snippet that you provided.
grid.tbody.on("change", ".k-checkbox", function() {
var checkbox = $(this);
var nextRow = checkbox.closest("tr").next();
// Note: the row should be expanded at least once as otherwhise there will be no child grid loaded
if (nextRow.hasClass("k-detail-row")) {
// And toggle the checkboxes
nextRow.find(":checkbox")
.prop("checked", checkbox.is(":checked"));
}
});
Also note that it's not .master as in the second demo, but .k-checkbox, as you are not providing a template in the first column (which the second demo does and the checkbox there has the master class).

How can i click kendo grid first row on page load

I have Kendo grid id = AddressID. when page load how can i click the first row automatically?
i tried the code below but no luck
var grid = $("#AddressGrid").data("kendoGrid");
grid.select("tr:eq(1)");
i tried this it selects the row but i want to trigger click
$(document).ready(function () {
var grid = $("#AddressGrid").data("kendoGrid");
grid.select(grid.tbody.find("tr:eq(1)").click());
});
If your data hasn't been loaded yet, there is nothing to select. You will have to specify the dataBound event and add you own handler.
Update: The change event fires whenever a row is selected either programatically or by the user's mouse.
$("#grid").kendoGrid({
dataSource: {
type: "odata",
transport: {
read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Customers"
},
pageSize: 20
},
height: 550,
sortable: true,
selectable: "row",
pageable: { refresh: true, pageSizes: true, buttonCount: 5 },
columns: [
{ field: "ContactName", title: "Contact Name" },
{ field: "ContactTitle", title: "Contact Title" },
{ field: "CompanyName", title: "Company Name" },
{ field: "Country" }
],
change: onChange,
dataBound: onDataBind // Callback handler
});
function onDataBind(e) {
this.select("tr:eq(0)"); // this === $("#grid").data("kendoGrid")
}
function onChange(arg) {
const selected = [...this.select()].pop(); // multi-select is off
const record = this.dataItem(selected);
console.log(record.ContactName);
}

VSTS extensions - Hyperlinks in Grid Source

Made my own VSTS extension that returns a Grid with a list of bugs read using a wiql.
I want the (UI Control) Grid to include the bug title and hyperlink to the bug url so that it is possible to click on the title to jump to the bug. I could not find any possibility to do that, but I do not believe that it is not possible.
This is how I'm building my source to the grid:
var sourceArray = workItems.map(function (w) {
return [
w.id,
w.fields["System.Title"],
w.fields["System.State"],
w.fields["GrundfosScrum.gfSeverity"],
w.fields["GrundfosScrum.gfLikelihood"],
w.fields["System.AssignedTo"]];
});
And later:
var options = {
width: "100%",
height: "500px",
source: sourceArray,
columns: [
{ text: "ID", index: 0, width: 100, headerCss: "mystyle" },
{ text: "Title", index: 1, width: 200, headerCss: "mystyle" },
{ text: "State", index: 2, width: 100, headerCss: "mystyle" },
{ text: "Severity", index: 3, width: 200, headerCss: "mystyle" },
{ text: "Likelihood", index: 4, width: 200, headerCss: "mystyle" },
{ text: "Assigned To", index: 5, width: 300, headerCss: "mystyle" },
]
};
I tried to replace w.fields["System.Title"] with w.fields["System.Title"].link(w.url), the result was html hyperlink in the table instead of a hyperlink inside the grid.
Any ideas?
This is not supported by add link in the grid. But you can call Open row details method to to achieve the feature you want. Get the URL information and open a new window when the openRowDetail method is triggered.

For anyone else is struggling with this like I was (as the documentation is pretty poor for the more granular stuff), I did it as follows.
Firstly, in the column definition in the later versions you just add a hrefIndex to the field you wish to bind e.g.
{ text: "Path", index: "path", width: 600, hrefIndex:'branchUrl' },
This works for the most part, but there doesn't appear to be (or at least, in the version I'm using) a binding for the target. So instead, I'd override the _drawCell function call as follows:
{ text: "Path", index: "path", width: 600, hrefIndex:'branchUrl', getCellContents : renderHref }
Where renderHref is:
var renderHref = function(rowInfo, dataIndex, expandedState, level, column, indentIndex, columnOrder){
var indent;
var cell = document.createElement('div');
cell.className = 'grid-cell';
var width = column.width || 20;
cell.style.width = isNaN(width) ? width : width + "px";
var jCell = $(cell);
var hrefText = this.getColumnValue(dataIndex,column.hrefIndex,-1);
var text = this.getColumnText(dataIndex,column,columnOrder);
jCell.append($("<a/>").attr("href", hrefText).attr('target','_blank').text(text));
return jCell;
};
Note that in my override I haven't bothered with the same logic as the original _drawCell for the indents etc., as I didn't need it.
This ensures that the hyperlink is rendered within the div container as a grid cell within the grid, and also allows you to set the target.

Kendo Grid Row Selection Client-side Persistence Issue

We have selections persisting, maybe just a bit too much. :D
For example, if you have a multipage kendo grid with client side data, do this with a client side kendo grid:
Select a row on Page 1
Go to Page 2
Select a row on Page 2 THEN deselect it and select another row
Go back to Page 1 (row selection persists)
Go back to Page 2
Row selection persists, but also the row that was previously deselected is also selected.
Is there a solution to this? Something we can use in the change event:

How to change grid column value on DataBound event

I have the following Grid,
<div class="kotgrid">
</div>
And I bound the data as following. Here I want to change timedelay column value on DataBound event,
$(".kotgrid").kendoGrid({
dataSource: dataSource,
dataBound: function (e) {
var grid = this;
grid.tbody.find('>tr').each(function () {
var dataItem = grid.dataItem(this);
var d = new Date();
var currentTime = parseTime(dataItem.servertime);
var currenTime = d.getHours() + ":" + d.getMinutes();
var meanTime = diff(orderTime2, currenTime2)
//I want to set this meanTime in timedelay coloumn. How can I achieve this?
})
},
filterable: true,
scrollable: true,
columns: [
{ hidden: true, field: "orderitemid" },
{ field: "tableid", title: "Table No" },
{ field: "itemname", title: "Items" },
{ field: "quantity", title: "Quantity" },
{ field: "modifier", title: "Modifier" },
{ hidden: true, field: "orderedtime", title: "Time Delay" },
{ field: "timedelay", title: "Time Delay" },
{ hidden: true, field: "alert" },
{ hidden: true, field: "category", groupHeaderTemplate: "#= value #" },
{ command: { text: "Pickup", click: showDetails} }
],
mobile: "phone",
editable: false,
selectable: "row",
height: "600px"
});
I don't know how to achieve it. Any help will be highly appreciable.
Thanks in advance.
You don't need to iterate over the <tr> elements, unless you only want to do it for the current page. You can just iterate over grid.dataSource.data().
So you could do something like:
var data = this.dataSource.data();
$(data).each(function() {
var d = new Date();
var currentTime = parseTime(this.servertime);
var currenTime = d.getHours() + ":" + d.getMinutes();
var meanTime = diff(orderTime2, currenTime2)
// set on dataItem
this.set("timedelay", meanTime);
});
Regardless of how you get access to the dataItem, you can set any property using the set method (the data source contains Model items which inherit from ObservableObject).
