We are using Kendo Grid in Asp.Net MVC application. The grid is configured and mapped to a Odata WebAPI for server filter to a Odata controller. Currently, any filter on two or more than two columns works with AND condition for filter. I want to convert into OR instead of AND. How can I do that ?

I am trying to sort my grid. Nothing happens and I'm getting the following console error:
kendo.all.js:164 Uncaught TypeError: r[n].call is not a function at init.trigger (VM376 kendo.all.min.js:25) at init.d (VM376 kendo.all.min.js:61) at init.trigger (VM376 kendo.all.min.js:25) at init._click (VM376 kendo.all.min.js:54) at HTMLTableCellElement.d (jquery-1.12.3.min.js:2) at HTMLTableCellElement.dispatch (jquery-1.12.3.min.js:3) at HTMLTableCellElement.r.handle (jquery-1.12.3.min.js:3)I created this Dojo to duplicate the problem: https://dojo.telerik.com/@dojolee/AFEqOfiZ

Hi,
I've recently found an issue with the combobox where a user can type in any number on the combobox and it will save if the foreign key exists on the database - regardless of checking whether or not the value is valid for use or not.
Why does the combobox treat typing in a random number as the FK of the control anyway when it doesn't do the same thing if you type in a random character?
Anyway the above is a question for a different time but after finding this out, I've found there's an article on how to avoid these kind of situations using JavaScript on this page:
https://docs.telerik.com/kendo-ui/knowledge-base/prevent-submission-of-missing-value
While trying to implement this logic, I can see that it's working (by not allowing the random number selection to be saved), but I've noticed there's actually an error on the first round of "select" call as the loading icon is displayed on the combo box.
The specific line is the "this.select(0)" line from the code snippet below:
if (this.value() && this.selectedIndex == -1) { this.dataSource.filter({ value: this.value(), field: this.options.dataTextField, operator: "contains" }); this.select(0); <=== this line is causing the issue. if ( this.selectedIndex == -1 ) { this.text(""); }}
Upon closer inspection, I see that there's a 500 error being thrown due to the "Page" parameter being set to NaN and the "PageSize" parameter being set to 0.
https://.../Items?sort=&group=&filter=NameDisplay~contains~%2712%27&page=NaN&pageSize=0
Any subsequent searches works without any issues and sets the "Page" and "PageSize" to the correct values.
https://.../Items?sort=&page=1&pageSize=80&group=&filter=NameDisplay~contains~%2712%27
This is very strange as the 500 error (above) only displays the first time this.select(0) is called, but any subsequent times will work without any issues.
While trying to reproduce this, I've found that it only occurs when the combobox has a valuemapper set to it.
.Virtual(v => v.ItemHeight(26).ValueMapper("itemsValueMapper"))
When the valuemapper function is removed from the combobox, the this.select(0) functions runs without any issues.
The value mapper is required for my comboboxes as it provides a good way to virtualise my lists.
My datasource is using webapi as below:
.DataSource(source =>{ source.Custom() .ServerFiltering(true) .ServerPaging(true) .PageSize(80) .Type("webapi") .Transport(transport => { transport.Read(a => a.Url(itemsUrl)); }) .Schema(schema => { schema.Data("Data") .Total("Total"); });})
Is there any work around that can be done for this?
Or even better, is there a way to prevent the combobox from binding random number values typed into the control?

Hi, we always load all js files at the bottom of a page because of performance. Before the </body> closing tag.
If we shift the JS files from head to the end of the file, Kendo controls are not working.
All the JS files are loaded correct if we check the network traffic with firebug tool.
Is it an known issue? and we have always to load all the scripts in head?
I made a 2nd quick test with the keno example code.
Open kendoui.trial.2012.3.1114\wrappers\aspnetmvc\Examples\Areas\razor\Views\Shared\_WebLayout.cshtml and shifted the following scripts to the bottom. Than load e.g. the datepicker example page (http://localhost/kendo/razor/web/datepicker/index)
<script src="@Url.Content("~/Scripts/jquery.min.js")"></script>
<script src="@Url.Content("~/Scripts/kendo.web.min.js")"></script>
<script src="@Url.Content("~/Scripts/kendo.aspnetmvc.min.js")"></script>
<script src="@Url.Content("~/Scripts/console.min.js")"></script>
<script src="@Url.Content("~/Scripts/prettify.min.js")"></script>
Same problem. If I open the datepicker test page. Datepicker is not working.
Thanks for your help.
