RichTextbox example or sample in or how to insert or store richtextbox data into database and display richtextbox data from database in gridview using

May 7, 2011

Here I will explain how to use richtextbox and how we can save our richtextbox data in database and how we can retrieve and display saved richtextbox data into our application using

Today I am writing this post to explain about freely available richtextbox. Previously I worked on one social networking site for that we got requirement to use richtextbox at that time we search so many websites to use richtextbox but we didn’t find useful ones. Recently I came across one website and I found one free available richtextbox. We can validate and we can use richtextbox very easily and by using this richtextbox we can insert data in different formats like bold, italic and different color format texts and we can insert images also. To use free Richtextbox download available dll here FreeTextbox . After download dll from that site create one new website in visual studio and add FreeTextbox dll reference to newly created website after that design aspx page like this 

After that Design your aspx page like this 

<%@ Register Assembly="FreeTextBox" Namespace="FreeTextBoxControls" TagPrefix="FTB" %>
<html xmlns="">
<head runat="server">
<title>Richtextbox Sample</title>
<script type="text/javascript">
function validate() {
var doc = document.getElementById('FreeTextBox1');
if (doc.value.length == 0) {
alert('Please Enter data in Richtextbox');
return false;
<form id="form1" runat="server">
<FTB:FreeTextBox ID="FreeTextBox1" runat="server">
<td valign="top">
<asp:GridView runat="server" ID="gvdetails" AutoGenerateColumns="false">
<asp:TemplateField HeaderText="RichtextBoxData">
<asp:Label ID="lbltxt" runat="server" Text='<%#Bind("RichtextData") %>'/>
<asp:Button ID="btnSubmit" runat="server" OnClientClick="return validate()"
Text="Submit" onclick="btnSubmit_Click" /><br />
<asp:Label ID="lbltxt" runat="server"/>
After that run your application richtextbox appears like this 

Now our richtextbox is ready do you know how we can save richtextbox data into database and which datatype is used to save richtextbox data and do you know how to display richtextbox on our web page no problem we can implement it now.

To save richtextbox data we need to use datatype nvarchar(MAX) now Design table like this in your SQL Server database and give name as RichTextBoxData

Column Name
Data Type
Allow Nulls
Int(Set Identity=true)
After that add following namespaces in code behind

using System.Data;
using System.Data.SqlClient;
Now write the following code in code behind 

SqlConnection con = new SqlConnection("Data Source=SureshDasari;Integrated Security=true;Initial Catalog=MySampleDB");
protected void Page_Load(object sender, EventArgs e)
protected void BindGridview()
SqlCommand cmd = new SqlCommand("select RichTextData from RichTextBoxData", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
gvdetails.DataSource = ds;
protected void btnSubmit_Click(object sender, EventArgs e)
SqlCommand cmd = new SqlCommand("insert into RichTextBoxData(RichTextData) values(@Richtextbox)", con);
cmd.Parameters.AddWithValue("@Richtextbox", FreeTextBox1.Text);
FreeTextBox1.Text = "";

Hi Suresh
i have problem wit tis cod at saving data with style in tbl

the Error is:-
A potentially dangerous Request.Form value was detected from the client (FreeTextBox1="sdsd").


Anonymous said...

You might want to add Server.HtmlEncode(freetextbox.Text) when saving to the database and Server.HtmlDecode() when retrieving. Otherwise a serious security problem exists.

Subhash, you have to set ValidateRequest="false" on the @Page line, that opens the door to security problems but you should be ok if you use HtmlEncode/Decode.

The task is looking for "LC.exe" in the "bin" subdirectory beneath the location specified in the InstallationFolder value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v6.0A.
