Hello,
HTML data to MSSQL I saved as HTML can not be displayed again.
text area HtmlEditorExtender and grid text area HtmlEditorExtender.
How do I make.

database table:

CREATE TABLE [dbo].[XHABER] (
    [ID]         BIGINT         IDENTITY (1, 1) NOT NULL,
    [HABER]      NVARCHAR(MAX) NOT NULL,
    [ADSOYAD]    NVARCHAR (50)  NULL,
    [CREATEDATE] DATETIME2 (7)  DEFAULT (getdate()) NULL
);

aspx; HtmlEditorExtender text area:

<asp:TextBox ID="txtAcik" runat="server" Font-Names="Verdana" Font-Size="8pt" Height="132px"
                    MaxLength="4096" TextMode="MultiLine" Width="940px" style="margin-left: 0px" BackColor="White">
    <asp:HtmlEditorExtender ID="HtmlEditorExtender1" runat="server" TargetControlID="txtAcik">

grid ItemTemplate:

<itemtemplate>
                        <asp:TextBox ID="TextBoxText" runat="server" Width="900px" TextMode="MultiLine" Text='<%# Bind("HABER") %>' Height="150">
<asp:HtmlEditorExtender ID="HtmlEditorExtender1" TargetControlID="TextBoxText" DisplaySourceTab="false" runat="server">
<toolbar>
<asp:Undo />
<asp:Redo />
<asp:Copy />
<asp:Paste />
</toolbar>

save sql command;

String query = "INSERT INTO XHABER " +
              " (HABER,ADSOYAD,CREATEDATE)" +
              " VALUES " +
              " (@HABER,@ADSOYAD,@CREATEDATE)";

               SqlCommand sqlCommand = new SqlCommand(query, sqllConn);

               sqlCommand.Parameters.Add("@HABER", SqlDbType.NVarChar, 19000, "HABER");
               sqlCommand.Parameters.Add("@ADSOYAD", SqlDbType.NVarChar, 50, "ADSOYAD");
               sqlCommand.Parameters.Add("@CREATEDATE", SqlDbType.DateTime, 100, "CREATEDATE");

               sqlCommand.Parameters["@HABER"].Value = txtAcik.Text;
               sqlCommand.Parameters["@ADSOYAD"].Value = Session["ADSOYAD"];
               sqlCommand.Parameters["@CREATEDATE"].Value = DateTime.Now.ToString();

               sqlCommand.Transaction = sqlTransaction;
               sqlCommand.ExecuteNonQuery();
               sqlTransaction.Commit();

It turns html code in the text section.
