I have the following code that uses the upload control to take a spreadsheet from our end user and uploads it and then parses it out into our objects.

var workbook = new kendo.spreadsheet.Workbook({});
workbook.fromFile(file).then(function() {
  Do lots of things;
});

I have had zero issues with this block for the most part. However one of our end users has tried to upload a file and they are running into issues. When I debug the code it hits the fromFile, and then goes right past the then. I had multiple breakpoints inside the then, and none of them were being hit. In my last attempt I let it run for almost an hour before I killed it. I tried wrapping it in a try catch to see if it was erroring out and nothing. I tried to upload the file on the demo for the api (https://docs.telerik.com/kendo-ui/api/javascript/ui/spreadsheet/methods/fromfile) and it loads fine there. 

I am at a loss and would love some insight. I have attached the spreadsheet that is causing issues hoping that someone can shed some light on it for me.

I have a spreadsheet that gets data loaded from a database. I want to add validation to a range of cells, but I never know how many columns or rows until after the data is loaded. So my question is: How do I do this with jquery? The validation is fairly simple. Each character can be a number or a colon : 

Thank you in advance

To illustrate the probelm I will use a simple example. I'm using the following code in the OnSelect() event handler:  

sheet.range(1,5,1,1).select();

The problem is that it never really highlights the correct cell and the cell it does select varies depeding on whether I use the left, right, up or down scroll key to navigate.  I'm not sure what is going on under the covers, but I'm guessing that the issue has to do with the fact that the selection was changing from one cell to another before the event was called, therefore, there is some soft of clash or confusion between the two select events.

I use the exact same code when I initalize the spreadsheet and it works perfectly. Inside the event handler though, I cannot figure out what it's doing.

Also, is there any documentation on the arguments that are passed to event handlers. There is a lot of stuff going in there but I cannot find any good documentation on it? I find that the API documentation does not go very deep, especially with events.

If you have defined an action for OnSelect, is there a way to cancel the navigation from within the function? I think Kendo does this with Validation. If you add Validation to a cell, then enter invalid data and try to navigate to another cell, the navigation is cancelled until you either fix the data or Cancel the input. Is there a way to replicate that behavior in my own code within the OnSelect event. There is no equivalent to blur when you leave a cell so the next best thing would be to do something as you select another.

Hi,

I have a requirement for a multi-select drop down within each cell of a specific column within a Kendo spreadsheet control.

Is this possible? I can't find any documentation around this. I would be really appreciative if someone could help me with code samples/demos

Thanks

Ian

I have written my own data validation in a Kendo Spreadsheet that executes when OnChange is fired. From what I can tell, this event happens when I change the contents of the cell then either click on another cell or scroll using the arrow key -- in Html this would have been onBlur. To that end, everything is working well. What I am not able to do though is reset the focus back to the cell that was in error. Within the OnChange function I execute sheet.range(rangeString).select(), but Kendo ignores this and continues moving to the next cell when OnChange is completed. Is there a way to stop this action?

Thank you in advance.

Hello ,

        to: "DATEVALUE(\"1/1/2050\")",
        allowNulls: true,
        type: "reject",
        titleTemplate: "Start Date validation error",
        messageTemplate: "Start Date should be between 1899 and 2050 year."
