Hi,

I have code similar to this:

http://dojo.telerik.com/OfiMU/7

I want to bind the dropdownlist to a nullable field on the model.  The user should be able to select a value from the list or the select the first optionLabel in order to put the value back to null.  So I added the k-option-label with a value field of null, however when selecting this value in the drop down the model is set to the empty string.  This is a problem as when saved to the database it causes a foreign key exception.   How do I set up the dropDownList to allow it to bind to nullable properties on the model?

Thanks

I am looking to see if there is any type of widget similar to the attachment, I know that DevExpress has this type of control and I believe Telerik Ajax for WebForms. I have found a similar control but it strictly a jquery plugin and I have also found an implementation somewhere on this forum posted from back in 2013, but the fiddle was rather confusing and not entirely what I was looking for.

So is there a control like this, or has anyone had to build something similar to this?

I am using KendoUi tree list with AngularJs. I have large amount of data (~3000 +) which is being updated after each 4 seconds. I have observed that whenever records are updated, it freeze the screen. Is there any solution?

Here is dojo link.Steps to run the test app:

1: Click on Add Data button

2:Turn on "Auto update". It will update records after 4 seconds. Now observe the behavior.

Update code is as follow:

Thank you.

Hello KendoUI Team,

My team is currently exploring using Kendo's Spreadsheet capabilities in one of our applications.  One issue we've encountered that we were hoping you could shed some light on is the behavior that occurs when copy/pasting disabled cells.

Scenario 1:

    - Set A1 as Disabled.  Copy B1 into A1.  A1 does not change because it is disabled.

Scenario 2:

    - Set A1 as Disabled.  Copy A1 into B1.  B1 is now also disabled with A1's value.

Both Scenarios "make sense" from a copy pasting sense, but Scenario 2 is certainly less than ideal for what we are trying to achieve.  Our goal is to have a sheet contain certain read-only "ID" columns that are immutable and users cannot change cells from enabled/disabled states.  However if a User were to copy one of these disabled read-only cells into another enabled cell, that change becomes permanent as the user cannot change the cell back to enabled nor can they undo their action as the cell is now read-only.  Is this currently a bug that will be fixed in the near future or do you have any suggested work-arounds?

The only thing that comes to mind is hard-coding all the columns we want to keep enabled and to enable those ranges again whenever the change event is triggered, but this doesn't feel like an efficient solution once our spreadsheets scale large enough.

Best,

Jeff

I get an "Invalid or unexpected token" error in the console when attempting to bind a datasource with any column that starts with a number or contains some non-standard characters (e.g., 360_Comment or Interview_&_Notes). Is there a fix forthcoming or a workaround I can do in the code without writing every cell value out myself?

Hi,

I'm trying to reuse the same data from the datasource in on 3 different places on the webpage without recalling the web api.

I'm trying to get this piece of code to work, but without success.
Anyone sees what i'm doing wrong here?

I'm trying to add a filter where i a column should equal a value.

I was wondering how to insert a row above the first row of the spreadsheet when binding to a datasource. I can achieve the desired result by specifying the cells I want by looping through the datasource and specifying the cell values dynamically, but this slows everything down considerably.
