Hi reetuSharma,
I was wondering if you mean CKEditor 5 ? If not, could you please share the resource about CSEDITOR5?
In case you misspell the name of the eidtor plugin, I will show you how to use CKEditor 5.
Regarding the image upload, you have to configure the CKEditor with either
Easy Image or CKFinder.
EasyImage is a kind of CKEditor Cloud Services that could keep the image you upload. However, CKFinder is a browser-based file uploader with its server-side connectors, which
you need to code more to integrate.
Below I have applied for a trial for the EasyImage account.
Html:
<head runat="server">
<title></title>
<script src="https://cdn.ckeditor.com/ckeditor5/12.0.0/classic/ckeditor.js"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<h1>Classic editor</h1>
<asp:TextBox ID="txtarea" runat="server" TextMode="MultiLine" ClientIDMode="Static"></asp:TextBox>
<script>
ClassicEditor
.create(document.querySelector('#txtarea'), {
cloudServices: {
tokenUrl: 'https://xxxx.xxxx.com/token/dev/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
uploadUrl: 'https://XXXX.XXXX.com/easyimage/upload/'
}})
.catch(error => {
console.error(error);
});
</script>
</div>
</form>
</body>
Demo:

Hope this can help you.
Best regards,
Sean
