I'm using the telerik mvc grid which shows up fine with the proper css classes applied and has data in it but the paging doesn't seem to work... When I click on the one of the page numbers at the bottom of the grid it throws this error:
The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'
I realized that I didn't have the scripts registered so I put them in:
#Html.Telerik().ScriptRegistrar.DefaultGroup(Sub(groups)
groups.Add("~/Scripts/2011.2.712/telerik.common.min.js")
groups.Add("~/Scripts/2011.2.712/telerik.grid.min.js")
End Sub)
Also tried:
#Html.telerik().ScriptRegistrar()
When it tries to register these scripts it complains that it cannont find telerik.common.js. I looked in the telerik folder (program files) where I got the script files originally and there is no telerik.common.js only the min version of it...
Any advice would be greatly appreciated!
Try to add it this way (without .min. )
group.Add("telerik.common.js").
Telerik ScriptRegistrar automatically converts it to "telerik.common.min.js"

I am working on a Drupal project which is using the Editable fields module.
Using that module I'm exposing a dropdown list of text options. It works just great. You click on the list, select an option and the option is updated via Ajax.
My challenge is I'm trying to change the options programmatically via jQuery. Using the following code:
jQuery('select#edit-field-status-0-field-status-und').val(1);
... my browser console area is happy with the code but the Ajax update does not take place.
I tried:
jQuery('select#edit-field-status-0-field-status-und').val(1).change();
Again no errors but the Ajax event still did not execute.
$('#edit-field-status-0-field-status-und').val("1");
will do the trick, as the only reason it wouldn't work would be that you have your select values as strings instead of numbers.
Alternatively the following is more detailed:
$('#edit-field-status-0-field-status-und option').eq(1).prop('selected', true);
Also this is not an 'AJAX' function, it's simply Jquery updating the DOM for the particular element.
The code I was using as recreated below was correct:
jQuery('select#edit-field-status-0-field-status-und').val(1).change();
I found out the reason why it wasn't working was because the ID of the target element changed dynamically.
So when I first inspected and found edit-field-status-0-field-status-und, the same element would change IDs to something like edit-field-status-0-field-status-und--1.
That was throwing things off and gave the impression my code wasn't working.
Thanks to #gts for your input.
I am using Sencha ExtJs grid 4.2 . I am using a Expander plugins for my grid and try to load data under expanded region from Ajax. Right now I am using this code to show data on expanding.
plugins: [{
ptype: 'rowexpander',
rowBodyTpl: new Ext.XTemplate(
'<br><img height="31" width="32" src="../upload/patient/thumb/{patient_image}">',
' <p><b>{fname}, {lname}</b></p>',
'<br> {accordian_view}'
)
}],
Here you can see that data is pre populated, but my requirement is to load data on expanding. I am trying hard to find the event or process to do it. But still no luck. If anyone have any idea please share.
Thanks in Advance
You might check out the expandbody event on the RowExpander plugin: http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.grid.plugin.RowExpander-event-expandbody
This event passes not only the row's bound record, but also the expanded element, so you could:
Request data via Ext.Ajax.request({...})
Handle response
Add content to expanded row
One thing to keep in mind, however, is the async nature of this approach. That is, the row is going to expand immediately, regardless of how long the subsequent request takes to come back. So it would probably be a good idea to do something like this instead when handling the expandbody event:
Add "loading" text/icon/whatever into expanded row area
Make Ajax request
Handle response
Replace loading text/icon/whatever with the data returned from the Ajax request
It's likely someone has already done so, but you could also (and I would highly suggest it) wrap this process into a custom plugin of your own that extends the RowPlugin. That way you could use it elsewhere in your app for any grid. If you end up creating a custom plugin, please share it with the community!
EDIT: A quick Google revealed a number of custom plugins that do precisely this. For example: https://github.com/nickbretz/Ext.ux.AsyncRowExpander/blob/master/AsyncRowExpander.js
Please see jsfiddle for example, blank out First Name field to have validation tooltip show. In a normal form the validation tooltip positions correctly to the right of each element. But in the popup editor for the grid it still trying to position the tooltip below the element as if it where editing inline. I have tried <span class="k-invalid-msg" data-for="FirstName"></span>but it doesn't change anything. Is there a setting I am missing to get this working in popupeditor? I guess I could manually modify the .k-tooltip but I am hoping for something more built in that handles the positioning correctly, because I am not very good at css.
As you've discovered, the error template for the grid is different to that provided by the kendo validator when applied to standard inputs.
Unfortunately, the validator that is created internally by the grid does not pass along any errorTemplate that you might define in the options object and by the time the "edit" event fires, the validator has already been created and the error template compiled, hence why setting the errorTemplate in the manner you describe does not work. Really, I think the Kendo grid should respect any user defined errorTemplate option but until it does we have to hack a little bit.
The key is to define a custom template and to apply it in the edit event, but instead of using the options object, set the private instance directly. Not ideal, but it works:
edit: function (e) {
e.sender.editable.validatable._errorTemplate =
kendo.template($('#tooltip-template').html());
}
See this updated fiddle for an example of what I think you might be looking to achieve.

(I would post this as a comment but not enough reputation yet...)
I'm successfully using nukefusion's solution. I, too, fought with the syntax error from jQuery for a long time and discovered through debugging that how you define the template is important. In particular, it appears that the template has to be written on a single line without any formatting, as in:
<script id="tooltip-template" type="text/x-kendo-template"><span class="k-widget k-tooltip k-tooltip-validation"><span class="k-icon k-warning"></span>#=message#</span></script>
If you try to make it "pretty" and format the html in the template, you get the syntax error. I don't know where the real bug is, as this sort of thing shouldn't cause an error. But it does and I stopped worrying about it once I got it to work correctly.
I am a newbie in JSF.I am creating a simple page with a checkbox and a readonly field.When I deploy to weblogic server ,I get what is expected output.
Now I have put autosubmit property on checkbox and partialtrigger propery on the other readonly field.My readonly field changes as expected on changing the state
of checkbox.I was curious to find out what Ajax code has been put in finally rendered page when i declare auto submit property to true.Basically I want to know
what is the html and ajax(javascript) code difference between the case when auto submit property is enabled and disabled.Is there any tool which can compare two source codes?
Thanks in advance.
Being able to see the exact difference in code may be difficult as the associated Javascript files for your JSF component toolkit have probably been minified, however you should at least be able to see the difference in the Javascript event declarations on the generated input element.
A tool like Firebug is the best choice as it gives you the ability to highlight DOM elements and view their corresponding styles, attributes, and events. It doubles as an excellent Javascript debugger as well, allowing you to place breakpoints in JS code so that you can walk through the execution of what is happening on each click event.
When autoSubmit is false, there is likely no Javascript event being triggered. When it is true however, there is likely an onclick event being triggered that is formulating an Ajax request. You might have a hard time figuring out what is happening because it is minified, however it is more than likely making such a call.

I have a view with a Telerik MVC grid. The grid uses ajax to select the data from the server. However when i use firebug to check the performance of it, it says thats its accessing the following url to get data:
http://localhost:61094/Grid/_BigGridBinding?Test-size=20
It gets the data correctly (no problem), but it looks very bad to have a Test-size 20 attached to it. I have tried to change my routes since its most likly a routing problem, but with no succcess. Anyone got any idea of how to change the route to get rid of this Test-size 20 and instead add it like /_BigGridBinding/20 (or similar).
The method signature that the grid is calling looks like this:
[GridAction(EnableCustomBinding = true)]
public ActionResult _BigGridBinding(GridCommand command)
I am using MVC 3 and the newest Telerik Controls.
The post URL is automatically built by the Telerik grid, so I'm not sure there is any way to get rid of the Test-size parameter. Routes take a given URL and extract the parts of the URL and map them to appropriate controller actions and parameters, so I don't think changing the routes will have any effect (since the URL is already built by the time the routing engine processes it).
That said, the query string parameter is constructed using the name of the grid. In your case, Test is the name of the grid, so the parameter is Test-size=20. So if that is what your concerned with, you can rename the grid to something more appropriate and the query string parameter will be named accordingly. For example, renaming the grid to BigGrid will result in a parameter BigGrid-size=20.
