Just as the title says, i have a div in the aspx side which has ID and runat=server.
I have 2 functions in the vb.net side code, on of which adds style as div.style.add("display","none").
In the other function i want to check if the div style display is none or not. How can i check that programatically?

Toggle vue2-editor view content to html

I am using vue2-editor and i want to toggle the content view of the editor like ckeditor or mailchimp editor does
It is possible using vue2-editor or quill?
You can have a computed property that either returns the actual text or uses a library like hypertext to generate html, the return value of the html would be contingent on another computed property and returns the html you want.
I also have a simpler solution, which I used once but need to take a look at my code in a few hours which is not in front of me.

How to write a CSS Selector selecting elements NOT having a certain attribute?

How to write a CSS Selector selecting elements NOT having a certain attribute?
I have 2 <div> nodes as follows:
First:
<div class="weEq5" style="will-change; width;">
<button class="_35EW6">
Second:
<div class="weEq5">
<button class="_35EW6">
I need to select the <div> (with the similar class) and each of them which have a similar descending <button> but without the style attribute.
XPath seems working fine as:
//div[#class and not (#style)]/button
I am looking for an equivalent CssSelector.
Trials:
div[class :not(style)]>button (doesn't works).
I have been through the following discussion but they seem to be discarding the class attribute as :not([class]) as in:
Can I write a CSS selector selecting elements NOT having a certain class?
Is it possible to define in CSS NOT to apply style if element have certain class? [duplicate]
I was looking in similar lines ending with :not(attribute).
I think more accurate CSS Selector is:
div[class]:not([style])>button
because the button element is a child of div element.
Hope it helps you!
That's the code you're looking for:
div:not([style]) button{
background-color: red;
}
Now let's break it down.
We have have four selectors in this example:
div and button - these select html elements. We can replace it for example with a class selector like .weEq5.
:not() - indicates that we want everything that does not qualify as the selector inside the brackets.
[style] - an attribute selector which is very powerful. We can place inside the not any other css selector like html tag names (button or div), class names or ids.
The combination of div:not([style]) means that we want all divs that do not have a style attribute. After which we have a space and a button means that we want all the buttons that are inside the above selector.
Adding a > before the button div:not([style]) > button will only select button elements which are direct children of the selected div. It will exclude from selection buttons that are deeper inside the div.
Normally, you would write :not([style]) to match an element that does not have a style attribute, as described here which emphasizes the use of both () and [] brackets, in that order.
But if this isn't working in Selenium WebDriver, and worse still if :not(style) works exactly like how I would expect :not([style]) to, then that's a bug with its CSS selector parser, since :not(style) actually means "not a style element" which makes div:not(style) redundant as an element can only either be a div or a style but not both at the same time. Unless you absolutely require a selector, I strongly recommend using the XPath locator strategy instead of relying on quirks like this with Selenium WebDriver's CSS selector engine that force you to write selectors that are both incorrect and don't work anywhere else that accepts a selector.
I do not understand how the situation developed in the first place, where the structure of the page necessitates the CSS rules to be aware of whether "style=..." exists in the document itself. Or even why style=... is being used.
The style attribute is old-school now, pre-CSS I believe. It also takes precedence over anything in the CSS. That attribute does not accept CSS class names. It accepts only native html style properties like "width","height","font" - old-school stuff - ultimately those are what your CSS resolves to, no matter how fancy or obfuscated it is through frameworks: font, width, left, top, float.. and so on.
By use of the class attribute (instead of style) in the document you get infinite control from which to write smart selectors in your CSS.
You can put 3 classes in the class attribute of your div for example, if you want, and have your selectors apply styling to it if 2 of the classes are present but not if all 3 are there. Tonnes of flexibility, no need to override or use "style=..." in the document at all.

Does Dojo has Label property for checkBox or its widgets?

I am creating a CheckBox in dojo as shown below-
new CheckBox({
id:"chckBox",
checked: true,
label: "Save for future"
},"divId").startup();
The checkBox has no label when it is displayed. It just has the checkbox checked.
So my question is - Do I need to have 2 separate components to be laid out, one for checkBox and other one for the label ?? Can't I just combine this into 1 widget?
Isn't there something similar to ExtJS where you have the fieldLabel property in dojo as well?
As well, say there is the no other way to create the check box with the label, other than having to input fields, then say if I need to do dynamic show/hide, do I need to apply CSS property on both the widgets separately,right ?
Please let me know if I am wrong.
Thanks !
Yes, you are all right.
There is no "checkbox with label" widget in DOJO, you need to create them separately and style them separately as well.

Alter Rendered Page in Webbrowser Control

is there a way to alter the rendered HTML page in webbrowser control? What i need is to alter the rendered HTML Page in my webbrowser control to highlight selected text.
What i did is use a webclient and use the webclient.Downloadstring() to get the source code of the page, Highlight specific text then write it again in webbrowser. problm is, images along with that page does not appear since they are rendered as relative path.
Is there a way to solve this problem? Is there a way to detect images in a webbrowser control?
Not sure why you need to change the HTML to lighlight text, why not use IHighlightRenderingServices?
To specify a base url when loading HTML string you need to use the document's IPersistMoniker interface and specify a url in your IMoniker implementation.
I suggest you do it a different way, download and replace the text using the webbrowser control, this way your links will work. All you do is replace whatever is in the Search TextBox with the following, say the search term is "hello", then you replace all occurances of hello with the following:
<font color="yellow">hello</font>
Of course, this HTML can be replaced with the SPAN tag (which is an inline version of the DIV tag, so your lines wont break using SPAN, but will using DIV). But in either case, both these tags have a style attribute, where you can use CSS to change its color or a zillion other properties that are CSS compatible, like follows:
<SPAN style="background-color: yellow;">hello</SPAN>
Of course, there are a zillion other ways to change color using HTML, feel free to search the web for more if you want.
Now, you can use the .Replace() function in dotnet to do this (replace the searched text), it's very easy. So, you can Get the Whole document as a string using .DocumentText, and once all occurances are replaced (using .Replace()), you can set it back to .DocumentText (so, you're using .DocumentText to get the original string, and setting .DocumentText with the replaced string). Of course, you probably don't want to do this to items inside the actual HTML, so you can just loop through all the elements on the page by doing a For Each loop over all elements like below:
For Each someElement as HTMLElement in WebBrowser1.Document.All
And each element will have a .InnerText/.InnerHTML and .OuterText/.OuterHTML that you can Get (read from) and Set (overwrite with replaced text).
Of course, for your needs, you'd probably just want to be replacing and overwriting the .InnerText and/or the .OuterText.
If you need more help, let me know. In either case, i'd like to know how it worked out for you anyway, or if there is anything more any of us can do to add value to your problem. Cheers.

attaching Tooltip to item without fixed element 'id'

I'm trying to add tooltips to a Dojo application that I recently inherited. The problem I'm having is that everything is created with dojoAttachPoint identifiers instead of with id's , such as :
so, I can't use "connectId= " when defining the tooltip, until I get a hold of the element's id that I want to connect to. Basically my question is, how can I find the id based on the dojoAttachPoint?
Thanks much for any suggestions!
The attach point is either going to be a domNode or a Widget based on whether it has a dojoType or not so if you have an attachPoint to a widgit then you can access connectid with this.myAttachWidget.connectid assuming that the attachPoint is in a widgets template.
