How do I get the total number of rows in a grid?

[Elliot]

I want to enable/disable menu items based on whether there are any rows in the grid.  How do I find if there are any rows?

Hi Elliot,

 
You can use the grid dataSource API methods to check if there is any records in the grid:

var grid = $("#Grid").data("kendoGrid");
var dataSource = grid.dataSource;

//records on current view / page
var recordsOnCurrentView = dataSource.view().length;
//total records
var totalRecords = dataSource.total();

Kind Regards,

Hi, I'm also trying to get the number of rows to display it on the top of the page.
So I did the thing you did, but both functions are returning 0 ...

Here is my code : 

var grid = $("#objectsGrid").data("kendoGrid");
var dataSource = grid.dataSource;

//records on current view / page
var recordsOnCurrentView = dataSource.view().length;
//total records
var totalRecords = dataSource.total();

console.log(dataSource);
console.log("totalRecords : " + totalRecords);
console.log("recordsOnCurrentView : " + recordsOnCurrentView);

 

And this is what I see in the Chrome console : 

Can you help me ? Thank you

Hello Antoine,

Thank you for the example.

After testing it, I can assume that this is a timing issue.

I can suggest using an event which will be fired after the Grid is initialized or a large enough timeout:

It works great !

I just increased the delay, because I have a lot of records in my grid.

Thank you very much

Has this recently changed? I have been attempting to return the count of rows, but when i use the .data for the kendo grid the console return undefined.

Hello, Nathan,

In general, the best place to take the number of items is on the dataBound event of the Grid as this will ensure that it will be available:
