Delete multiple And Search Record in GridView Control using Checkbox in asp .net c#

Hello Friends!
Here I will teach you How to Delete Multiple Records In Grid View Control. For This Purpose I have used checkbox in the Grid View to delete multiple records.

Step 1 : Create a table in sql server database for bind grid view .Here I am created one table that name it dsh_poco_regi. For the quickly operation I filled the manually data in database table.





Step 2 : Open Visual Studio and create New  Project (ASP.NET Web Application).
Step 3 : Add One Grid View Control in Default.aspx. Here I also perform the search data and Highlight that data in  GridView Control so I have use one dropdownlist ,one textbox  inside gridview and one search button.
Html Code of Default.aspx page

WPF DataGrid : Insert Edit Update And delete operation

Hellow Friends !!
In  This article I will Explain you How to build simple WPF application to View ,Update, Insert and Delete Data.
Here I am using Data Grid to display, edit, add and delete data from SQL server database.
The Data Grid Control similar to ASP.NET Grid control. Data Grid Control is the powerful Control to available to developer and it has various collections to bind and provides various events to work with.
For Implementing Insert,Edit,Update and Delete Operation in WPF application,
I have created One table in database.

Table name is “dsh_wpfCRUD”.


Next Step 
1.Open Visual Studio
2.Create a new Project (WPF Application) name it “WpfCRUD” (You   can Also change Project name as you need.)


Next Step
3.In this Application  create appropriate GUI using XAML code. I have taken four textbox 
Two radio button, two Combo Box, two Button and one Data Grid Control to perform Operation of view ,edit and delete data.
I do this like below code.

MainWindow.xaml
<Window x:Class="WpfCRUD.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>
        <TextBox Grid.ColumnSpan="2" HorizontalAlignment="Left" Height="23" TextWrapping="Wrap" VerticalAlignment="Top" Width="120" Margin="143,34,0,0" Name="txtname"/>
        <Label Grid.ColumnSpan="2" Content="Name:" HorizontalAlignment="Left" Margin="48,34,0,0" VerticalAlignment="Top"  Target="{Binding ElementName=txtname}"/>

    </Grid>
</Window>

After write code the design will look like in below picture.


In the above code , I am using DataGridTemplateColumn, Edit and Delete button are added.

Insert edit update delete in repeater control in asp.net

In this post I will Explain How to Insert, Edit, Update, Delete And display data or CRUD Operation in Repeater control.

The Repeater is control for used in asp.net to display the Entire table data. Repeater control is the best control to display repeated data. It allows to customization of the layout by each repeated list of item and do lots of design customization. The Repeater Control may be bound database file, database table, XML file and other file to control. The Repeater control is very use full Control to  display a repeated data that are bound to the control because we can create Table, Unordered lists, ordered list, anchor tags, Image galleries etc.

For Implementing Insert, Edit, Update and  delete Operation in Repeater first you have to create one table in database.
Create Table name is “dsh_RepeaterDemo"


Next step
1.Open Visual Studio
2.Create a new Project (ASP.NET Web Service) name it “RepeaterDemo” (You   can Also change Project name as you need.).

Next Step
Design aspx page In that page I am use three textbox and two button and one repeater control.

insert edit update delete using web service in asp .net C#

Hello Friends !!
Web services are Web-based applications accessed using the protocols of the web to be used by the web applications. It is basically a class consisting of method that could use by other applications. In simple word it is a part of web application that provides facility to communicate one system to another system through http (Hyper Text Transfer Protocol).

In this post I will explain insert ,edit ,update and delete operation through web service in asp.net c#.Now I have described how to insert,edit,update and delete operation with the help of web service and using with linq to sql.Complete step are given below.

1.Open Visual Studio
2.Create a new Project (ASP.NET Web Service) name it (WebServiceCrudOpe).
When open “ASP.NET Web Service”.By Default some code are prewritten in Service1.cs page as shown in below image.


Here I am using linq to sql for the CRUD Operation by web service.
For the crud operation ,first I create a table as shown in below figure.


Next step is to add a new item “LINQ to SQL Classes”.
See below figure after drag and drop table.


Now next step is create method for Insert,Edit,Update and Delete operation in Service1.asmx.cs page
Service1.asmx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data.Linq;
namespace WebServiceCrudOpe
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
    {
        DataClasses1DataContext db = new DataClasses1DataContext();
        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }
        //Method for Insertind data into database
        [WebMethod]
        public dsh_webserviceCRUD InserData(dsh_webserviceCRUD obj)
        {
            dsh_webserviceCRUD webobj = new dsh_webserviceCRUD();
            webobj.Name = obj.Name;
            webobj.Address = obj.Address;
            webobj.ContactNo = obj.ContactNo;
            db.dsh_webserviceCRUDs.InsertOnSubmit(webobj);
            db.SubmitChanges();
            return webobj;
        }
        //Method for Read/Get data from database
        [WebMethod]
        public List<dsh_webserviceCRUD> ReadData()
        {
            List<dsh_webserviceCRUD> listdata = new List<dsh_webserviceCRUD>();
            listdata = (from o in db.dsh_webserviceCRUDs
                        select o).ToList();
            return listdata;
        }
        //Method for Get Specif ID from database
        [WebMethod]
        public List<dsh_webserviceCRUD> ReadSpecific(int id)
        {
            List<dsh_webserviceCRUD> listspecific = new List<dsh_webserviceCRUD>();
            listspecific = db.dsh_webserviceCRUDs.Where(o => o.Id == id).ToList();
            return listspecific;
        }
        //Method for Updating data of database
        [WebMethod]
        public dsh_webserviceCRUD UpdateRec(dsh_webserviceCRUD obj)
        {
            dsh_webserviceCRUD updatedata = new dsh_webserviceCRUD();
            updatedata = db.dsh_webserviceCRUDs.Where(o => o.Id == obj.Id).FirstOrDefault();
            updatedata.Name = obj.Name;
            updatedata.Address = obj.Address;
            updatedata.ContactNo = obj.ContactNo;

            db.SubmitChanges();
            return updatedata;
        }
        //Method for Deleting data of database
        [WebMethod]
        public dsh_webserviceCRUD DeleteRec(int id)
        {
            dsh_webserviceCRUD DelRec = new dsh_webserviceCRUD();
            DelRec = db.dsh_webserviceCRUDs.Where(o => o.Id.Equals(id)).FirstOrDefault();
            db.dsh_webserviceCRUDs.DeleteOnSubmit(DelRec);
            db.SubmitChanges();
            return DelRec;
        }
    }
}
Here “[WebMethod]” is responsible to execute code on web.
Now Run the Web Service .


After run webservice you get URL (http://localhost:58126/Service1.asmx) that shown in above figure.
Copy the URL for the further use.

Now Move to Make a client side Project for the use of Web Service.
3 .Open Visual Studio
4. Create a new Project (ASP.NET Web Application) name it (WebserviceCRUD).
After that I have design  Default.aspx page with three textbox ,one button and one GridView for CRUD operation.
Default.aspx

</html>
Next step to add web service reference in project. Right click on project and select “Add Web Reference” as shown in below figure.


After select “Add Web Reference” you will get a window . In “Add Web Reference”window ,paste  URL (Which I copy in above scenario) within URL Textbox.Then Click on Go button,and see all available Web Service Method will appear on pane below.
Note give the specific “Web reference name “.I am using “localhost1”.


After click on “Add Reference” button, you can see  solution explorer, you will find “localhost1” is added in solution as shown in below figure.


After open  Default.aspx.cs and write following code.
Default.aspx.cs

            GridView1.DataSource = listdata1;
            GridView1.DataBind();
        }
