In my app there is field change font Actually using that user can change the font of whole application.Is this possible actually if i have 100 field in my project (may be different different font size on every page ).How can user change the font size .so that it can reflect on whole application.As I goggled i found that there is functionality of zoom in and zoom out .It is not a good way to do that .? is there any way to change font of whole application?
You can create a style dynamically and apply it to all elements within body.
Demo
$('#select_font').on('change', function () {
var style;
var font = $(this).val();
if ($('head').find('style.font').length === 0) {
style = $('<style class="font">.font { font-size: ' + font + ' !important; }</style>');
$('head').append(style);
$('body *').addClass('font');
} else {
$('body *').removeClass('font');
$('style.font').empty();
style = '.font { font-size: ' + font + ' !important; }';
$('style.font').append(style);
$('body *').addClass('font');
}
});
This article shows a nice way of doing it in CSS only.

Key is to only using em, then you can switch font size globally by changing the base for em.

Having a small issue with tooltips in the editor, read the api but can't understand what it is saying and I can't seem to find examples anywhere that I can understand either.
I have set up a Classic Editor build, and all the buttons on the toolbar have tooltips with the default position below the button, I want to be able, just for this one instance of the editor, to change the tooltip position to above the buttons instead. The instance is set up like this:
ClassicEditor.create( document.querySelector( '#content' ) )
.then( editor => {
console.log( 'Editor was initialized', editor );
this.annEditorInstance = editor;
} )
.catch( err => {
console.error( err.stack );
} );
That creates an editor instance that is set up exactly as I want, except for the issue with the tooltip. How do I change this? Thanks in advance.
There are two approaches to the problem:
CSS
Tooltips elements have either .ck-tooltip_s or .ck-tooltip_n class. By default all CKEditor 5 tooltips have the former so you could override it in your styles and make it act like the later:
<style>
.ck.ck-tooltip.ck-tooltip_s {
bottom: auto;
top: calc(-1 * var(--ck-tooltip-arrow-size));
transform: translateY( -100% );
}
.ck.ck-tooltip.ck-tooltip_s .ck-tooltip__text::after {
top: auto;
bottom: calc(-1 * var(--ck-tooltip-arrow-size));
transform: translateX( -50% );
border-color: var(--ck-color-tooltip-background) transparent transparent transparent;
border-width: var(--ck-tooltip-arrow-size) var(--ck-tooltip-arrow-size) 0 var(--ck-tooltip-arrow-size);
}
</style>
JS
The UI of the editor is an MVC(VM) structure. The position of the tooltip can be controlled using the JS and the Button#tooltipPosition property ('s' or 'n').
E.g. you can access the toolbar UI elements using editor.ui.view.toolbar and change their properties:
editor.ui.view.toolbar.items.map( item => item.tooltipPosition = 'n' )
but note that not all toolbar items are buttons. Some, for instance, are dropdowns so you'd need to use item.buttonView.tooltipPosition = 'n' in that case. So unless you really want to use JS, I'd go with a simple CSS solution.
I am using dimple.js on a mobile device but when the text is too long for the tool tip is just goes off the screen instead of wrapping down. Is there a way to set a maximum width for the tooltip? I am currently using this code to show only certain info:
s.getTooltipText = function (e) {
return [
"Product Description: " + e.aggField[0],
"Volume: " + e.yValue
];
};
Thanks!
The quick and dirty way would be just to use CSS:
.dimple-tooltip{
width: 200px !important;
}
Note that this won't auto-wrap text though.
While I'm using Umbraco 7.2.1, I want the image I insert to be responsive (img-responsive) of bootstrap.
How can i do that?
I'm not sure how you are adding the images to your pages but I had this problem when I started using the new grid layout in Umbraco 7.2.
So if you are also using the grid layout what you need to do is open the view "Partial Views\Grid\Editors\Media.cshtml" and add the class there.
...
<img src="#url" class="img-responsive" alt="#Model.value.caption">
...
This will add the class to ALL images added to the grid layout with the standard "Image" grid editor.
You can add your own custom class to to images in
~/umbraco_client/tinymce3/plugins/umbracoimg/img/image.js
Look for where it says tinymce.extend(). It should end up looking something like this:
tinymce.extend(args, {
src: nl.src.value,
width: nl.width.value,
height: nl.height.value,
alt: nl.alt.value,
title: nl.alt.value,
rel: nl.orgWidth.value + ',' + nl.orgHeight.value,
class: 'img-responsive'
});
I've only done this in Umbraco 6, so hopefully the answer is still the same in Umbraco 7.
I don't advise altering anything in the /umbraco/ or /umbraco_client/ folders since any future updates will undo your changes, forcing you to reapply them.
Assuming you want to add a responsive class to images entered in the rich text editor, I would recommend creating a new css rule for img elements that adds the relevant properties from .img-responsive.
For example:
You add a rich text data type called bodyText to a document type in Umbraco. In your template for this document, wrap the rendering call in an element with the class .bodyText.
<div class="bodyText">
#Umbraco.Field("bodyText")
</div>
In your stylesheet, create a new rule for .bodyText img that inherits the properties from the .img-responsive class.
.bodyText img {
max-width: 100%;
height: auto !important;
}
Note !important on the height property. This is added to ensure that the inline-style added for height are overridden. When an editor changes the dimensions of an image in the rich text editor, tinyMCE will add the new dimensions to the image's inline style attribute, thus killing the responsive height.
I did it very easily in Umbraco 7.5.5, change /Umbraco/Js/umbraco.services.js:
$timeout(function () {
var imgElm = editor.dom.get('__mcenew');
var size = editor.dom.getSize(imgElm);
if (editor.settings.maxImageSize && editor.settings.maxImageSize !== 0) {
var newSize = imageHelper.scaleToMaxSize(editor.settings.maxImageSize, size.w, size.h);
// images must be responsive: commented 3 lines of code, added addClass with img-responsive,
// var s = "width: " + newSize.width + "px; height:" + newSize.height + "px;";
// editor.dom.setAttrib(imgElm, 'style', s);
editor.dom.addClass(imgElm, 'img-responsive');
editor.dom.setAttrib(imgElm, 'id', null);
if (img.url) {
//var src = img.url + "?width=" + newSize.width + "&height=" + newSize.height;
var src = img.url;
editor.dom.setAttrib(imgElm, 'data-mce-src', src);
}
}
}, 500);
I have problem with ASP.NET MVC Telerik Grid.
In my grid I have comment column and some columns contains too large text.
This effects to row height. I need that all rows have same height.
How I can reduce the text? I tried to add HTML abbr, but it doesn’t work.
Best regards Paul.
Using custom formatting, you can check the length of your text, and if the text length is greater than a certain number, you can limit the length by using substring. For example, if your comment column is called "Comment", you could do something like this:
Html.Telerik().Grid(Model)
.Name("MyGrid")
.CellAction(cell =>
{
if (cell.Column.Title != null)
{
if (cell.Column.Title.Equals("Comment"))
{
if (cell.DataItem.Comment.Length > 25)
{
cell.Text = cell.DataItem.Comment.Substring(0, 25) + "...";
}
}
}
});
Update
You asked about showing the complete comment. I don't know of a simple way built into the telerik control, but you can do it using css. I am using css code from kollermedia.at, but there are lots of examples of css tooltips if you want a different style.
In your css, put something like this:
/* tooltip */
a:hover {background:#ffffff; text-decoration:none;} /*BG color is a must for IE6*/
a.tooltip span {display:none; padding:2px 3px; margin-left:8px; width:130px;}
a.tooltip:hover span{display:inline; position:absolute; background:#ffffff; border:1px solid #cccccc; color:#6c6c6c;}
Then change the line in your view to this:
cell.Text = "<a class=\"tooltip\" href=\"#\">" + cell.DataItem.Comment.Substring(0, 25) + "<span>" + cell.DataItem.Name + "</span></a>";
When you hover over the shortened text, the complete text is displayed in a tooltip.
At the moment I have this:
tinyMCE.init({
// General options
mode : "exact",
elements : "fkField, lkField, ukcField, khField",
theme : "advanced",
plugins : "table",
width : "300",
height: "185",
// Theme options
theme_advanced_buttons1 : "fontsizeselect, bold,italic,underline,bullist, cleanup, |,justifyleft,justifycenter,justifyright",
theme_advanced_buttons2 : "tablecontrols",
theme_advanced_buttons3 : "",
theme_advanced_buttons4 : "",
theme_advanced_toolbar_location : "bottom",
theme_advanced_toolbar_align : "center",
theme_advanced_resizing : false
});
This gives me a editor with the size of 300x185.
Now in this editor, I would like to do so you can only write until the editor is full. (without the scroller)
So you are unable to enter more text, and the scroller should not appear (disable scrolling)
Right now you can at the bottom of inside the editor just make new line and it will add the scroller <- which i do not want to happen
How can i do this? Is this unpossible? I have made research for some time now, but maybe it's just me searching wrong..
Thanks
add in a ccs file the following code
.mceContentBody{
overflow-y:hidden!important;
}
and add the path of css file in content_css attribut of tinymce
content_css : /path/to/css/file.ss
You will need to write an own plugin. Check the editor height on each Keystroke (you may use the built in tinymce event onKeyUp). If the heigth changes remove the last inserted code.
EDIT: Howto get the current editor iframe heigth
var currentfr=document.getElementById(editor.id + '_ifr');
if (currentfr.contentDocument && currentfr.contentDocument.body.offsetHeight) { //ns6 syntax
currentfr.height = currentfr.contentDocument.body.offsetHeight + 26;
}
else if (currentfr.Document && currentfr.Document.body.scrollHeight) { //ie5+ syntax
currentfr.height = currentfr.Document.body.scrollHeight;
}
I got it to work by adding this to my extra tinyMCE CSS file:
IFRAME {overflow:hidden;}
Previously, the scrollbars were only off in Firefox. This fixes it for Chrome as well. However, it does add a gray bar the side of a scrollbar at the bottom, so I need to enlarge the height of my text editor.
for me it worked by just adding rules to a regular stylesheet, it wasn't needed to add a css file to content_css attribute (example is in scss)
.my-tinymce-container {
width: 200px;
.mce-edit-area {
height: 200px;
overflow-y: hidden;
}
}
A lot simpler and easy solution would be:
tinymce.init({
selector: '#container',
},
init_instance_callback: function (ed) {
tinymce.activeEditor.getBody().style.overflow = 'hidden'
},
});
Explanation:
In Init callback get the body for TinyMCE and change style as required.
In this case to remove scrollbar overflow = 'hidden'.
