Aspx:
<div id="Div1">Your name:</div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<div id="Div2">Your message:</div>
<dx:ASPxHtmlEditor ID="ASPxHtmlEditor1" runat="server">

<asp:Button ID="Button1" runat="server" Text="Save to File" onclick="Button1_Click" />
C#:
public partial class _Default : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
}
protected void Button1_Click(object sender, EventArgs e) {
string myHtml = ASPxHtmlEditor1.Html.ToString();
string fileName = TextBox1.Text + DateTime.Today.Date.ToShortDateString() + ".txt";
string fullFileName = Request.MapPath("Files/" + fileName);
StreamWriter streamWriter =
new StreamWriter(new FileStream(fullFileName, FileMode.Create, FileAccess.Write));

}
保存到数据库：
The ASPxHtmlEditor'a content can be saved as an HTML markup to a database the following ways:
- Using two-way (read/write) Data-Binding Expression (the <%# bind> expression).(自动绑定)
The following example illustrates the data-bound ASPxHtmlEditor within the ASPxGridView. After editing, the updated ASPxGridView content is saved to the database.
Aspx：<asp:AccessDataSource ID="AccessDataSource1" runat="server"
DataFile="~/App_Data/Data_28072008.mdb"
SelectCommand="SELECT * FROM [Table1]"
DeleteCommand="DELETE FROM [Table1] WHERE [ID] = ?"
InsertCommand="INSERT INTO [Table1] ([ID], [Name], [DescriptionHtml]) VALUES (?, ?, ?)"
UpdateCommand="UPDATE [Table1] SET [Name] = ?, [DescriptionHtml] = ? WHERE [ID] = ?">
<DeleteParameters>
<asp:Parameter Name="ID" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="Name" Type="String" />
<asp:Parameter Name="DescriptionHtml" Type="String" />
<asp:Parameter Name="ID" Type="Int32" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="Name" Type="String" />
<asp:Parameter Name="DescriptionHtml" Type="String" />
</InsertParameters>

- Using database queries
In the following example, the Save To DataBase button creates a connection with the Access DataBase and inserts the ASPxHtmlEditor's contents into a new tuple.
Aspx: <div id="Div1">Your name:</div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<div id="Div2">Your message:</div>
<dx:ASPxHtmlEditor ID="ASPxHtmlEditor1" runat="server">
</dx:ASPxHtmlEditor>
<asp:Button ID="Button1" runat="server" Text="Save to DataBase" onclick="Button1_Click" />
C#:public partial class _Default : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
}
protected void Button1_Click(object sender, EventArgs e) {
string MyHtml = ASPxHtmlEditor1.Html.ToString();
OleDbConnection myConnection = new OleDbConnection();
myConnection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=C:/Solutions/MyProject/App_Data/test.mdb";
myConnection.Open();
OleDbCommand myCommand = new OleDbCommand();
myCommand.Connection = myConnection;
myCommand.CommandText = "INSERT INTO Table1(Name,DescriptionHtml)
VALUES (@name,@message)";
OleDbDataAdapter dataAdapter = new OleDbDataAdapter();
dataAdapter.SelectCommand = myCommand;
dataAdapter.SelectCommand.Parameters.Add("@name",
OleDbType.VarChar, 50).Value = TextBox1.Text;
dataAdapter.SelectCommand.Parameters.Add("@message",
OleDbType.VarChar, 200).Value = ASPxHtmlEditor1.Html.ToString();
DataSet ds = new DataSet();
dataAdapter.Fill(ds, "Table1");
myConnection.Close();
}
}
