Disable width and height fields from image properties windows - asp.net

Disable width and height fields from image properties I am using ckeditor 4
CKEDITOR.replace('<%=txtCkEditor.ClientID %>', {allowedContent:'img[!src,alt];'});
By using above method it shows only image properties with width and height hidden and rest of the controls also get visible false. Kindly suggest me a solution for disabling the width and height fields from image properties windows.
Thanks in advance.

I'm not sure I entirely understand your question. It seems you want to hide the fields that allow input of height and width. Your initial solution doesn't seem to affect the dialog box, but what content gets saved. These are very different kinds of solutions. My answer assumes you're seeking to alter the image properties dialog box fields.
Based on this earlier question, I recommend adding the following configuration:
CKEDITOR.on('dialogDefinition', function(ev) {
var editor = ev.editor;
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
if (dialogName == 'image') {
var infoTab = dialogDefinition.getContents( 'info' );
infoTab.remove( 'txtWidth' ); // Remove width element from Info tab
infoTab.remove( 'txtHeight' ); // Remove height element from Info tab
}
});

How to make text area to fit dynamic content completely without any overflow?

This is an angular app (but anyone with css knowledge can help), where there is a text area with dynamic content.
So as the content item.text changes the text area should grow or shrink according to the content to fit the content perfectly without any overflow.
<textarea [value]="item.text" [placeholder]="item.text ? '' : 'Your Text Here...'" class="font-xl font-bold"></textarea>
// dont worry about the placeholder. you can ignore that.
Currently in my case scrollbar appears & it is not shrinking or growing with the dynamic content.
How can I achieve that?
Or if there is a way to convert a regular html <div> to a textarea, you can suggest that too. But prefers a solution for the above one.
I've tried css rules like, max-content fit-content etc... nothing is working out!
Install npm install ngx-autosize
in html add autosize
<textarea autosize [value]="item.text" [placeholder]="item.text ? '' : 'Your Text Here...'" class="font-xl font-bold"></textarea>
then in appmodule
put in imports: [AutosizeModule ],
Demo
This can't be accomplished with just css, it needs JavaScript that has quite a few corner cases and can be tricky. Such as, pasted input, input populated programatically, auto filled input, handling screen size changes correctly, and on and on, and doing so in a way that is reusable and performs well.
Given all that, I recommend using a lib for this.
I've used angular material's plenty of times with no issues, just add material to your project (can be done via angular CLI with ng add #angular/material) and either import the MatInputModule from #angular/material/input or TextFieldModule from #angular/cdk/text-field (TextFieldModule is quite a bit smaller) to the module where you want to use it, then do:
<textarea cdkTextareaAutoSize cdkAutosizeMinRows="5" [value]="item.text" [placeholder]="item.text ? '' : 'Your Text Here...'" class="font-xl font-bold"></textarea>
you can exclude the cdkAutosizeMinRows option and then it will default to 1 row, but you can use that option to set however many minimum rows you'd like to display. You can also use the cdkAutosizeMaxRows option to make it stop growing at a certain number of rows if you wish, otherwise it will grow indefinitely with the content.
blitz: https://stackblitz.com/edit/angular-4zlkw1?file=src%2Fapp%2Ftext-field-autosize-textarea-example.html
docs: https://material.angular.io/components/input/overview#auto-resizing-textarea-elements
https://material.angular.io/cdk/text-field/overview
You can't change the height of the textarea without Javascript. But you can use an editable div instead. In plain HTML something like this would serve the same purpose as an textarea and will resize automatically based on the content.
<div class="font-xl font-bold" contentEditable>Hello World</div>
If you use a <div> which you can edit then it can grow or shrink accordingly.
<div contenteditable="true">This is a div. It is editable. Try to change this text.</p>
The below will loop over the item and compare height to scrollHeight incrementing the height by lineHeight. Then resets the rows once the height is greater than the scroll height
(function () {
const el = document.querySelector('textarea');
dynamicallyResize(el);
el.addEventListener('change', function () { dynamicallyResize(el); });
})();
function dynamicallyResize(el) {
el == undefined && (el = this.target);
const lineHeight = 16;
let i = el.getAttribute('rows'),
height = Math.ceil(el.getBoundingClientRect().height);
el.style.overflow = 'visible'; //triger redraw
while(height < el.scrollHeight) {
height += lineHeight;
i++;
el.setAttribute('rows', i);
}
el.style.overflow = 'auto';
}
<textarea [value]="item.text" [placeholder]="item.text ? '' : 'Your Text Here...'" class="font-xl font-bold" rows="2">Starting text that exceeds the 2 row limit initially placed on this particular text area.</textarea>

How do I size a Firefox Add-on SDK popup/panel? Firefox Add-on SDK popup/panel too small

I followed the tutorial on creating a popup for an add-on in Firefox, and it worked great.
The issue I'm having now is that the popup it creates doesn't change size to fit the content I add to it. Instead, it adds scroll bars.
So, how do I change the size of a Firefox Add-on SDK popup to show all content?
You do have to deal with that yourself.
If you already know the desired size when creating the panel, you can pass the height and width as properties of the object to the Panel() constructor.
After a panel is created, its size can be changed by setting the height and width properties on it.
height and width values are numbers in pixels.
See https://developer.mozilla.org/en-US/Add-ons/SDK/High-Level_APIs/panel for a full documentation of how to use panels.
Though the tutorial and docs never say it, the height and width of a panel always defaults to the same small size.
To change it you can use the height and width parameters for the panel class.
If you want it to change automatically you can use this code:
//index.js
var panel = require("sdk/panel").Panel({
height: 200, //choose your default
width: 200,
contentURL: data.url("popup.html"),
contentScriptFile: data.url("auto_resize_popup.js")
});
panel.port.on("resize", function (size) {
console.log(size);
panel.resize(size.width, size.height);
});
...
//auto_resize_popup.js
var content = document.body;
var size = {};
size.width = content.offsetWidth + 2; //2 extra pixels get rid of scroll bars
size.height = content.offsetHeight + 2;
self.port.emit("resize", size);

set panel height sencha -touch

I am New In sencha -touch and need your help.
I add new panel and want to set the height of this panel in css.
this.clockContainer = new Ext.Panel({
id:'clock',
html:'00:00'
});
#clock {height:142px}
however,sencha calculates the height style to 91px (according to the html content) and ignores my css.
I dont want to add the height property to the panel like this:
this.clockContainer = new Ext.Panel({
id:'clock',
html:'00:00',
height:'142px'
});
what can I do?How can I prevent sencha calculates the height?
thank you.
edit: if I set the height property to '142px' it works fine but if I set it to '8.06em' senchs ignores it and calculate itself.
You need to add a cls attributes to your Ext.Panel like so
this.clockContainer = new Ext.Panel({
id:'clock',
html:'00:00',
cls:'clock-panel'
});
Then in your CSS you add this
.clock-panel .x-panel-body{
height:142px;
}
Hope it helps

How do I enable a Text class to accept html text and will I be able to calculate height and width?

When showing the html I would need to know the height of the text box in order to align things below it properly.
In order to pass it html and have it rendered as such you would set the htmlText property instead of the text property. Once the text box has been added to the display list you can get it's height just like normal.
If you are trying to get the value of the height and width immediately after setting insance.htmlText, you are not going to get the calculated size of the container. You can add an event listener for FlexEvent.UPDATE_COMPLETE or force validation to do it synchronously and use getExplicitOrMeasuredHeight(). Be careful when forcing validation, it is expensive and does not necessarily need to be done in most cases. I've included a right and wrong way of making it synchronous that was not entirely obvious to me at first.
Wrong:
var container : Box = new Box;
var text : Text = new Text;
container.addChild(text);
text.htmlText = "<b>THIS IS A TEST</b>";
trace( text.getExplicitOrMeasuredHeight() > 0 ) // False
Right:
var container : Box = new Box;
var text : Text = new Text;
container.addChild(text);
text.htmlText = "<b>THIS IS A TEST</b>";
text.validateNow(); // Forces the validation methods to run and update the component
trace( text.getExplicitOrMeasuredHeight() > 0 ) // True

is it even possible to expand a (horizontal) list's background with ajax?

I've got a list with list-style-none which needs to be able to add new items to itself via Ajax and have the background expand appropriately when it does. Adding via Ajax is easy, but every solution I try for the background fails me. I don't know if it's even possible; is it? I'm using a grid like this one:
http://jqueryui.com/demos/sortable/#display-grid
Both WebKit and Firebug are showing me skinny, empty bars when I hover over the enclosing divs and/or the enclosing ul tag. It appears that the minute you set a list loose with list-style-none and float:wherever, you give up control over its background. But that can't be right.
This is something I've run into a number of times. The problem is that floated elements aren't part of the normal box model, so they don't cause their parent elements to expand unless their parent elements are also floated. So if possible, float the ul or containing div.
Edit:
See quirksmode for another css-only workaround.
Could you provide a sample of your code? Also, why does the list have display:none set?
For instance, should be as simple as this:
HTML:
<ul id="dest"></ul>
JS:
// Simplified example, most likely wrapped in $.ajax
// This is the AJAX response function
function(data, response) {
var items = json.parse(data);
$.each(items, function() {
// Assumes item has a name property
$('#dest').append($('<li>' + this.name + '</li>'));
});
}
Should be just that simple. You shouldn't need the hide the list initially, as you can simply append list items and have the display update appropriately.
Hope that helps.
You need to explicitly set the width and height for the area.
Check out this link for Horizontal Scrolling: http://valums.com/scroll-menu-jquery/
Here is the script:
$(function(){
//Get our elements for faster access and set overlay width
var div = $('div.sc_menu'),
ul = $('ul.sc_menu'),
// unordered list's left margin
ulPadding = 15;
//Get menu width
var divWidth = div.width();
//Remove scrollbars
div.css({overflow: 'hidden'});
//Find last image container
var lastLi = ul.find('li:last-child');
//When user move mouse over menu
div.mousemove(function(e){
//As images are loaded ul width increases,
//so we recalculate it each time
var ulWidth = lastLi[0].offsetLeft + lastLi.outerWidth() + ulPadding;
var left = (e.pageX - div.offset().left) * (ulWidth-divWidth) / divWidth;
div.scrollLeft(left);
});
});
Basically, you need to update the ulWidth and divWidth when you add the new item.
Then just set the background image to repeat horizontally and you should be set.
ul.sc_menu {background:transparent url(image.png) repeat scroll 0 0;height:100px}
Note: You will need to set the height; otherwise you will not see the background because the li are floated.
For dealing with the float element, maybe you should know it's characteristic, gotcha, and how to deal with it.
See the links below, it also have demo, so you can understand the concept:
