public HtmlEditorCssFileCollection CssFiles { get; }Public ReadOnly Property CssFiles As HtmlEditorCssFileCollection| Type | Description |
|---|---|
| HtmlEditorCssFileCollection | An HtmlEditorCssFileCollection object that represents the collection of items identifying the external CSS files. |
The CssFiles property allows you to specify your custom CSS files to apply to the editor.
The code sample below demonstrates how to add a CSS file to the collection.
protected void Page_Load(object sender, EventArgs e) {
HtmlEditorCssFile cssFile = new HtmlEditorCssFile("~/CSSFiles/Styles.css");
ASPxHtmlEditor1.CssFiles.Add(cssFile);
}
The code sample below demonstrates how you can specify CSS rules for the body tag to define the standard text style within the ASPxHtmlEditor.
[CSS]
body.dxhedesignviewarea, /* or body.dxhedesignviewarea_{theme postfix} if you are using ASPxHtmlEditor has the non-default theme */
body {
font-family: Tahoma;
font-size: 12pt;
}
This example illustrates how to customize the ASPxHtmlEditor's placeholders by using CSS styles.
