Hi,

I'd like to provide data icon attribute to items inside a listview bound to a data source and that uses a template. As 'li' element is added internally when data source is provided to the listview, I can't find any way to show the icon on item's left side.

Thanks

I am using kendoui widgets with knockoutjs for datasource. I have a checkbox that is data bound to `StartClientFromWebEnabled` observable variable. An input text box is visible only when the checkbox ic checked (`StartClientFromWebEnabled` is true). The input has a required attribute. I want the required validation to be triggered only when the checkbox is checked.


Here is my html: 
 
    <table>
        <tr>
            <td><label for="startClientFromWebEnabled">Client Launch From Web:</label></td>
            <td><input type="checkbox" id="startClientFromWebEnabled" name="startClientFromWebEnabled" data-bind="checked: StartClientFromWebEnabled, enable: IsEditable" onchange="startClientFromWebToggleRequiredAttribute()" /></td>
        </tr>
        <tr data-bind="visible: StartClientFromWebEnabled">
            <td><label for="mimeType">Protocol:</label></td>
            <td>
                <input  id="mimeType" name="mimeType" data-bind= "value: MimeType, enable: IsEditable" />
                <span class="k-invalid-msg" data-for="mimeType"></span>
            </td>
        </tr>
    </table>


I tried some scenarios including setting `onChange event` on the checkbox with the following javascript function adding and removing the required attribute:


    startClientFromWebToggleRequiredAttribute = function () {
        var checkbox = document.getElementById("startClientFromWebEnabled");
        var mimeType = document.getElementById("mimeType");
        if (checkbox.checked) {
            mimeType.setAttribute("required", "required");
        }
        else {
            mimeType.removeAttribute("required");
        }
    }


The problem is I will need this functionality for many dependent properties in my application and my option is to make this function generic with some parameters and call it from the html with the corresponding paramater values like this:


    toggleRequiredAttribute = function (checkboxElement, inputElement1, inputElement2 ... ) {
        var checkbox = document.getElementById(checkboxElement);
        var inputElement1 = document.getElementById(inputElement1);
        if (checkbox.checked) {
            inputElement1.setAttribute("required", "required");
        }
        else {
            inputElement1.removeAttribute("required");
        }
    }


    <input type="checkbox" id="startClientFromWebEnabled" name="startClientFromWebEnabled" data-bind="checked: StartClientFromWebEnabled, enable: IsEditable" onchange="toggleRequiredAttribute('startClientFromWebEnable', 'mimeType')" />


I really do not like this scenario. I wonder is there something like a conditional validation in kendoui that trigger only when some condition is satisfied. Any other suggestions are also welcome. 

Does somebody know the release date for Kendo UI Q3 2012 Beta?

Hi,

I am aware that I can pass additional data to the tree view nodes when constructing the HTML list:



However, I construct my tree view in JS, from a JSON object and have (AFAIK) no way to pass additional data to the nodes. I am thinking of something like:



How should I solve this? (Background: I need this "id" to save it into local storage, and later use it when user reloads page so that tree view "remembers" which node should be selected.)

Thanks!

I'm trying to intercept the adding/updating of records to a Grid.

It seems the saveChanges event is triggered at the appropriate time -- just before sending the data to the server, but how can I extract the data that's being saved/updated and how can I prevent the action if necessary?

Thanks

How to synchronize a node (with its children eventually changed), when the datasource changes externally of treeview.
For instance the changes can be done in the same HTML page in an other control as a grid or a form.
We need to resyncf all thre tree rebinding to datasource or we can reload only a single node?

how to put validation on multiple checkbox with popup editor.?

how to put validation on multiple checkbox with popup editor..?

I have a numeric textbox that looks like this:
Every time someone hits the up/down arrow in the numerictextbox, i want the change event (placeMarker) to run.  But it only runs after the person has clicked outside of the numerictextbox, i.e. it loses focus.  Is there a way around this?

Hi,

Initially i will have the add button and when i click the add button the list view edit mode will appear and then i will add
the data. Then i will add another list and so on and finally i want to save all the listviews at a time.
how can i do that using kendo ui. Hope you will understand my question.

Thanks and Regards,
