Editor TagHelper Overview
The Telerik UI Editor TagHelper for ASP.NET Core is a server-side wrapper for the Kendo UI Editor widget.
The Editor allows you to create rich textual content through a What-You-See-Is-What-You-Get (WYSIWYG) interface and generate widget value as an XHTML markup.
The Editor is part of Telerik UI for ASP.NET Core, a
professional grade UI library with 100+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.
Initializing the Editor
The following example demonstrates how to define the Editor by using the Editor TagHelper.
<kendo-editor name="editor">
</kendo-editor>
Basic Configuration
The tools collection of the Editor TagHelper is passed through the nest <tools> tag.
<kendo-editor name="editor">
<tools>
<tool name="bold" />
<tool name="italic" />
<tool name="underline" />
<tool name="fontName" />
</tools>
</kendo-editor>
@(Html.Kendo().Editor()
.Name("editor")
.Tools(tools => tools
.Clear()
.Bold()
.Italic()
.Underline()
.FontName()
)
)
You can adjust and set up the tools in the tools collection through the <tools> tag. To define their items collection, use the <tool-items> and <tool-item> tags.
<kendo-editor name="editor">
<tools>
<tool name="fontName">
<tool-items>
<tool-item text="Default site font" value="Arial,Verdana,sans-serif" />
<tool-item text="Monospaced font" value="monospace" />
</tool-items>
</tool>
</tools>
</kendo-editor>
@(Html.Kendo().Editor()
.Name("editor")
.Tools(tools => {
tools.Clear();
tools.FontName(items => items
.Add("Default site font", "Arial, Verdana, sans - serif")
.Add("Monospaced", "monospace")
);
})
)
To specify a chunk of content in the Editor TagHelper, use the <content> tag or the value attribute.
<kendo-editor name="editor">
<content>
<p>Some content.</p>
</content>
</kendo-editor>
@(Html.Kendo().Editor()
.Name("editor")
.Value(@<text>
<p>Some content.</p>
</text>)
)
The ImageBrowser and FileBrowser dialogs are configured through the <image-browser> and <file-browser> tags.
<kendo-editor name="editor">
<image-browser file-types="*.png,*.gif,*.jpg,*.jpeg">
<transport upload-url="/ImageBrowser/Upload" image-url="/shared/UserFiles/Images/{0}">
<create url="/ImageBrowser/Create"/>
<read url="/ImageBrowser/Read" />
<destroy url="/ImageBrowser/Destroy" />
</transport>
</image-browser>
<file-browser>
<transport upload-url="/FileBrowser/Upload" file-url="/shared/UserFiles/Images/{0}">
<create url="/FileBrowser/Create" />
<read url="/FileBrowser/Read" />
<destroy url="/FileBrowser/Destroy" />
</transport>
</file-browser>
</kendo-editor>
@(Html.Kendo().Editor()
.Name("editor")
.ImageBrowser(imageBrowser => imageBrowser
.Image("~/shared/UserFiles/Images/{0}")
.Read("Read", "ImageBrowser")
.Create("Create", "ImageBrowser")
.Destroy("Destroy", "ImageBrowser")
.Upload("Upload", "ImageBrowser")
)
.FileBrowser(fileBrowser => fileBrowser
.File("~/shared/UserFiles/Images/{0}")
.Read("Read", "FileBrowser")
.Create("Create", "FileBrowser")
.Destroy("Destroy", "FileBrowser")
.Upload("Upload", "FileBrowser")
)
)
The serialization, deserialization and paste-cleanup settings are configured with the <serialization>, <deserialization>, and <paste-cleanup> tags respectively.
<kendo-editor name="editor">
<deserialization custom="myDeserialization" />
<serialization custom="mySerialization" entities="false" />
<paste-cleanup custom="myPasteCleanup" keep-new-lines="true" />
</kendo-editor>
@(Html.Kendo().Editor()
.Name("editor")
.Deserialization(deserialization => deserialization.Custom("myDeserialization"))
.Serialization(serialization => serialization.Custom("mySerialization").Entities(false))
.PasteCleanup(pasteCleanup => pasteCleanup.Custom("myPasteCleanup").KeepNewLines(true))
)
To configure other Editor options, such as PDF export, immutables, rezisability or messages, use the respective inner tags—<pdf>, <immutables>, <resizable>, or <messages>.
<kendo-editor name="editor">
<immutables enabled="true" />
<resizable toolbar="true" content="true" />
<pdf paper-size="A4" />
<messages bold="Strong" />
</kendo-editor>
@(Html.Kendo().Editor()
.Name("editor")
.Immutables(true)
.Resizable(resizable => resizable.Toolbar(true).Content(true))
.Pdf(pdf => pdf.PaperSize("A4"))
.Messages(messages => messages.Bold("Strong"))
)
