How to validate Summernote using javascript/jquery and reset the value

2017-03-07T21:25:00.000+05:30

In this article I am going to show you how to validate and reset Summernote (To know more about summernote click on link).

So, for this firstly we get the value of editor and store in a variable just like (Editor is id of summernote) :

   1:  var code = $('#Editor').summernote('code');

After this we replace symbols like <, >, / with space ' ', because of the default value of summernote is '<p> <br/> &lt/;p>'
Final code is :

   1:   var code = $('#Editor').summernote('code');

   2:          var filteredContent = (code).replace(/\s+/g, '');

3:

   4:          if (filteredContent.length == 0) {

   5:              $('.note-editable').css({ 'border': 'solid 1px red' }).focus();

   6:              //  if summernote is empty

   7:              isValid = false;

   8:          }

9:

Now, for reset the summernote value :

   1:   $('#Editor').summernote('code', '');

I hope ,it will help you.

How to fix header of table or gridview or datatable without using any plugin and without scroll in table

2017-03-02T21:23:00.002+05:30

In this article I am going to tell how fix make table header freeze using javascript and CSS.

You can see live demo below

Name	Phone	Address
table1 data1	table1 data1	table1 data1
table1 data2	table1 data2	table1 data1
table1 data3	table1 data3	table1 data1
table1 data4	table1 data4	table1 data1
table1 data5	table1 data5	table1 data1
table1 data6	table1 data6	table1 data1
table1 data7	table1 data7	table1 data1
table1 data8	table1 data8	table1 data1
table1 data9	table1 data9	table1 data1
table1 data10	table1 data10	table1 data1

You can see above table header is freezed while we scroll down to the page. For this you have to set the header class 'floatingHeader' and gridview class 'persist-area"' of gridview/datagrid or any other table like :

   1:   <asp:GridView runat="server" HeaderStyle-CssClass="persist-header" CssClass="persist-area" ID="grdView">

   2:          <Columns>

   3:              <asp:TemplateField>

   4:                  <ItemTemplate></ItemTemplate>

   5:              </asp:TemplateField>

   6:              <asp:TemplateField>

   7:                  <ItemTemplate></ItemTemplate>

   8:              </asp:TemplateField>

   9:          </Columns>

  10:      </asp:GridView>

Then define floatHeader style like :

   1:   .floatingHeader {

   2:        position: fixed;

   3:        top: 0;

   4:        visibility: hidden;

   5:      }

Finally wirte javasctip code as below: In the below javascript code we are creating a clone of table header and show/hide on the event of scroll.

   1:  <script>

   2:   function UpdateTableHeaders() {

   3:         $(".persist-area").each(function() {

4:

   5:             var el             = $(this),

   6:                 offset         = el.offset(),

   7:                 scrollTop      = $(window).scrollTop(),

   8:                 floatingHeader = $(".floatingHeader", this)

9:

  10:             if ((scrollTop > offset.top) && (scrollTop < offset.top + el.height())) {

  11:                 floatingHeader.css({

  12:                  "visibility": "visible"

  13:                 });

  14:             } else {

  15:                 floatingHeader.css({

  16:                  "visibility": "hidden"

  17:                 });

  18:             };

  19:         });

  20:      }

21:

  22:      // DOM Ready

  23:      $(function() {

24:

  25:         var clonedHeaderRow;

26:

  27:         $(".persist-area").each(function() {

  28:             clonedHeaderRow = $(".persist-header", this);

  29:             clonedHeaderRow

  30:               .before(clonedHeaderRow.clone())

  31:               .css("width", clonedHeaderRow.width())

  32:               .addClass("floatingHeader");

33:

  34:         });

35:

  36:         $(window)

  37:          .scroll(UpdateTableHeaders)

  38:          .trigger("scroll");

39:

  40:      });

  41:  </script>

That's it finally you will get a table with freeze header:-).

How to use HTML Editor (Summernote) in asp.net c#

2017-02-27T22:35:00.002+05:30

In this article I am going to tell how to use HTMl editor in simple and easy way using Summernote super easy editor.

So, for this we need five plug-ins, I am giving CDN link below you can download from it.

After this,

First create a new project or website in Visual studio.

And add following code:

<html xmlns="http://www.w3.org/1999/xhtml"><br />
<head runat="server">
    <title></title>
<script src="https://code.jquery.com/jquery-1.12.0.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/summernote/0.8.1/summernote.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/summernote/0.8.1/summernote.js"></script>
    <script type="text/javascript">
        $(function () {
            // Set up your summernote instance
            $("#<%= txtSummernote.ClientID %>").summernote();
          
            // When the summernote instance loses focus, update the content of your <textarea>
            $("#<%= txtSummernote.ClientID %>").on('summernote.blur', function () {
                $('#<%= txtSummernote.ClientID %>').html($('#<%= txtSummernote.ClientID %>').summernote('code'));
                });
        });

</script>
</head>
<body>
    <form id="form1" runat="server">
<div id="summernote">
Copy some text, click here, control+A, delete content, write 'hello', press enter, control+v</div>
        <div>
            <asp:TextBox ID="txtSummernote" runat="server" TextMode="MultiLine" Rows="2"></asp:TextBox>
            <asp:Button runat="server" Text="save" ID="save1" OnClick="save1_Click" />
        </div>
</form>
</body>
</html>

This will give the output some like :

Most important line to add in your page directive is :

ValidateRequest="false"

So, when you run this code and click on the save button you might be getting this error something like:

To remove this error Add this in you web.config inside system.web tag:

2013-05-30T22:48:00.001+05:30

How To Disable Auto Complete Text From Textbox

Some times for security purpose it is required to disable auto complete text from textbox. It also work on asp.net server tag.

To do it, In html Form tag have one property i.e. autocomplete. Set it to off. Like:

When autocomplete on:

When autocomplete off:

Insert and search from database using WCF:

2013-02-16T23:08:00.001+05:30

Insert and search from database using WCF:

INTRO:

Windows Communication Foundation is an acronym of WCF.

Basically WCF is based on Service Oriented Architecture(SOA). It is a technology to develop applications that are based on SOA.

A WCF clients connect to WCF through an Endpoint. Endpoint contains Address, Binding, and Contracts. We can use ABC to remember these keywords.

Address: Address denotes the address of WCF Service. The address contains two elements: address of the service and the transport protocol, used to communicate with the service.

Binding: Binding denotes how communication done between service and client, means what protocol is used to access the service. Protocols like HTTP, TCP, MSMQ etc.

Contracts: Contract means agreement between two parties . Similarly in WCF it is the agreement between client and service. Contract defines what service does. It have method definition and return type and data. Mainly it contains,

Service Contract

Operation Contract

Data Contract

Data Member

About Application: In this application you can add new student to database and search name using student id.

Lets Start:

Table name: Student

Id is primery key (int)

Name is varchar(50)

To create WCF Service Firstly creates Interface that contains Service in IService1.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace WcfService2

{

[ServiceContract]

public interface IService1

{

[OperationContract]

string setdata(student s);

[OperationContract]

student getdata(string nm, int i);

}

[DataContract]

public class student {

int _id;

string _name;

[DataMember]

public int Id {

get {

return _id;

}

set {

_id = value;

}

[DataMember]

public string Name {

get {

return _name;

}

set {

_name = value;

}

Now, implement that interface in Service1.svc

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

using System.Data.SqlClient;

using System.Configuration;

namespace WcfService2

{

public class Service1 : IService1

{

string con = ConfigurationManager.AppSettings["con"];

SqlConnection conn;

public string setdata(student s)

{

try

{

conn = new SqlConnection(con);

conn.Open();

SqlCommand com = new SqlCommand("insert into student (name) values(@student)", conn);

com.Parameters.AddWithValue("@student", s.Name);

com.ExecuteNonQuery();

return "inserted";

}

catch (Exception ex)

{

return ex.ToString();

}

finally {

conn.Close();

}

public student getdata(string nm,int id)

{

student s = new student();

try

{

conn = new SqlConnection(con);

SqlCommand com = new SqlCommand("select name from student where id=@id", conn);

conn.Open();

com.Parameters.AddWithValue("@id", id);

SqlDataReader read = com.ExecuteReader();

read.Read();

s.Name = read[0].ToString();

s.Id =Convert.ToInt32( id);

return s;

}

catch (Exception ex)

{

s.Name = "no result found";

return s;

}

finally {

conn.Close();

}

Then add new project in WCF service solution and add new web application

Add following code in web form.aspx file inside form tag:

Id<asp:TextBox runat="server" ID="sid">

</asp:TextBox>

<asp:Button ID="search" Text="search" runat="server" onclick="search_Click" /><br />

<asp:Label runat="server" ID="name">

</asp:Label><br />

<asp:Label runat="server" ID="id"></asp:Label>

</div>

<hr />

<br />

Name<asp:TextBox ID="inm" runat="server"></asp:TextBox>

<asp:Button ID="insert" runat="server" Text="insert" onclick="insert_Click" />

<asp:Label runat="server" ID="res"></asp:Label>

Now ASP page looks like :

In code behind file add the following code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.ServiceModel;

using WebApplication2.ServiceReference2;

namespace WebApplication2

{

public partial class WebForm1 : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void search_Click(object sender, EventArgs e)

{

Service1Client client = new Service1Client();

student s = new student();

s= client.getdata("",Convert.ToInt32(sid.Text));

name.Text=s.Name;

id.Text=s.Id.ToString();

}

protected void insert_Click(object sender, EventArgs e)

{

Service1Client client = new Service1Client();

student s = new student();

s.Name = inm.Text.ToString();

string res=client.setdata(s);

this.res.Text = res;

}

You have to copy this line by right clicking on Service1.svc file and click on option View in Browser: Service1Client client = new Service1Client();

Now, right click on Service1.svc file and click on option View in Browser:

And copy address

IN Web application right and select option ADD SERVICE REFERENCE

Paste copied address in new open small window like this and press GO button:

Now right click on webapplication and select set as startup project

Then set webform.aspx page as a start page and run project.
