Example

This example demonstrates how to replace placeholders with data specified as an object. When the Insert Signature button is clicked, the FirstName and LastName placeholders are replaced using the ASPxHtmlEditor.ReplacePlaceholders method’s ReplacePlaceholders(string html, Dictionary <String, String> placeholders) overload.

<dx:ASPxHtmlEditor ID="HtmlEditor" ClientInstanceName="HtmlEditor" runat="server">
    <Toolbars>
        <dx:HtmlEditorToolbar>
            <Items> ...</Items>
        </dx:HtmlEditorToolbar>
    </Toolbars>
    <Placeholders>
        <dx:HtmlEditorPlaceholderItem Value="DateNow" />
        <dx:HtmlEditorPlaceholderItem Value="TimeNow" />
        <dx:HtmlEditorPlaceholderItem Value="FirstName" />
        <dx:HtmlEditorPlaceholderItem Value="LastName" />
    </Placeholders>
</dx:ASPxHtmlEditor>
<dx:ASPxButton ID="SignatureButton" runat="server" OnClick="Insert_Signature" Text="Insert Signature" />
private Dictionary<string, string> PlaceholdersForSignature = new Dictionary<string, string>() {
    {"FirstName", "Mary"},
    {"LastName", "Bonn"}
};

// Replaces placeholders specified as a dictionary
protected void Insert_Signature(object sender, EventArgs e) {
    string html = HtmlEditor.Html;
    string newHtml = ASPxHtmlEditor.ReplacePlaceholders(html, PlaceholdersForSignature);
    HtmlEditor.Html = newHtml;
}
