Asp.net insert, Edit, update, delete data in gridview

By: Suresh Dasari Feb 9, 2011

Introduction:

In this article I will explain how to insert, edit, update and delete data in gridview using asp.net.

Description:

I have one gridview I need to write code to insert data into gridview after that I need to edit that gridview data and update it and if I want to delete the record in grdview we need to delete record simply by click on delete button of particular row to achieve these functionalities I have used some of gridview events those are

1 1) Onrowcancelingedit

2 2) Onrowediting

3 3) Onrowupdating

4 4) Onrowcancelingedit

5 5) Onrowdeleting

By Using above griview events we can insert, edit, update and delete the data in gridview. My Question is how we can use these events in our coding before to see those details first design table in database and give name Employee_Details

ColumnName	DataType
UserId	Int(set identity property=true)
UserName	varchar(50)
City	varchar(50)
Designation	varchar(50)

After completion table creation design aspx page like this

<title>Untitled Page</title>

.Gridview

{

font-family:Verdana;

font-size:10pt;

font-weight:normal;

color:black;

}

</style>

</head>

<body>

<div>

<asp:GridView ID="gvDetails" DataKeyNames="UserId,UserName" runat="server"

AutoGenerateColumns="false" CssClass="Gridview" HeaderStyle-BackColor="#61A6F8"

ShowFooter="true" HeaderStyle-Font-Bold="true" HeaderStyle-ForeColor="White"

onrowcancelingedit="gvDetails_RowCancelingEdit"

onrowdeleting="gvDetails_RowDeleting" onrowediting="gvDetails_RowEditing"

onrowupdating="gvDetails_RowUpdating"

onrowcommand="gvDetails_RowCommand">

<asp:TemplateField>

<asp:ImageButton ID="imgbtnUpdate" CommandName="Update" runat="server" ImageUrl="~/Images/update.jpg" ToolTip="Update" Height="20px" Width="20px" />

<asp:ImageButton ID="imgbtnCancel" runat="server" CommandName="Cancel" ImageUrl="~/Images/Cancel.jpg" ToolTip="Cancel" Height="20px" Width="20px" />

</EditItemTemplate>

<asp:ImageButton ID="imgbtnEdit" CommandName="Edit" runat="server" ImageUrl="~/Images/Edit.jpg" ToolTip="Edit" Height="20px" Width="20px" />

<asp:ImageButton ID="imgbtnDelete" CommandName="Delete" Text="Edit" runat="server" ImageUrl="~/Images/delete.jpg" ToolTip="Delete" Height="20px" Width="20px" />

</ItemTemplate>

<asp:ImageButton ID="imgbtnAdd" runat="server" ImageUrl="~/Images/AddNewitem.jpg" CommandName="AddNew" Width="30px" Height="30px" ToolTip="Add new User" ValidationGroup="validaiton" />

</FooterTemplate>

</asp:TemplateField>

<asp:TemplateField HeaderText="UserName">

<asp:Label ID="lbleditusr" runat="server" Text='<%#Eval("Username") %>'/>

</EditItemTemplate>

<asp:Label ID="lblitemUsr" runat="server" Text='<%#Eval("UserName") %>'/>

</ItemTemplate>

<asp:TextBox ID="txtftrusrname" runat="server"/>

<asp:RequiredFieldValidator ID="rfvusername" runat="server" ControlToValidate="txtftrusrname" Text="*" ValidationGroup="validaiton"/>

</FooterTemplate>

</asp:TemplateField>

<asp:TemplateField HeaderText="City">

<asp:TextBox ID="txtcity" runat="server" Text='<%#Eval("City") %>'/>

</EditItemTemplate>

<asp:Label ID="lblcity" runat="server" Text='<%#Eval("City") %>'/>

</ItemTemplate>

<asp:TextBox ID="txtftrcity" runat="server"/>

<asp:RequiredFieldValidator ID="rfvcity" runat="server" ControlToValidate="txtftrcity" Text="*" ValidationGroup="validaiton"/>

</FooterTemplate>

</asp:TemplateField>

<asp:TemplateField HeaderText="Designation">

<asp:TextBox ID="txtDesg" runat="server" Text='<%#Eval("Designation") %>'/>

</EditItemTemplate>

<asp:Label ID="lblDesg" runat="server" Text='<%#Eval("Designation") %>'/>

</ItemTemplate>

<asp:TextBox ID="txtftrDesignation" runat="server"/>

<asp:RequiredFieldValidator ID="rfvdesignation" runat="server" ControlToValidate="txtftrDesignation" Text="*" ValidationGroup="validaiton"/>

</FooterTemplate>

</asp:TemplateField>

</Columns>

</asp:GridView>

</div>

<div>

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

</div>

</form>

</body>

</html>

Now add the following namespaces in codebehind

using System;

using System.Data;

using System.Data.SqlClient;

using System.Drawing

After that write the following code

SqlConnection con = new SqlConnection("Data Source=SureshDasari;Integrated Security=true;Initial Catalog=MySampleDB");

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

BindEmployeeDetails();

}

protected void BindEmployeeDetails()

{

con.Open();

SqlCommand cmd = new SqlCommand("Select * from Employee_Details", con);

SqlDataAdapter da = new SqlDataAdapter(cmd);

DataSet ds = new DataSet();

da.Fill(ds);

con.Close();

if (ds.Tables[0].Rows.Count > 0)

{

gvDetails.DataSource = ds;

gvDetails.DataBind();

}

else

{

ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());

gvDetails.DataSource = ds;

gvDetails.DataBind();

int columncount = gvDetails.Rows[0].Cells.Count;

gvDetails.Rows[0].Cells.Clear();

gvDetails.Rows[0].Cells.Add(new TableCell());

gvDetails.Rows[0].Cells[0].ColumnSpan = columncount;

gvDetails.Rows[0].Cells[0].Text = "No Records Found";

}

protected void gvDetails_RowEditing(object sender, GridViewEditEventArgs e)

{

gvDetails.EditIndex = e.NewEditIndex;

BindEmployeeDetails();

}

protected void gvDetails_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

int userid = Convert.ToInt32(gvDetails.DataKeys[e.RowIndex].Value.ToString());

string username = gvDetails.DataKeys[e.RowIndex].Values["UserName"].ToString();

TextBox txtcity = (TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtcity");

TextBox txtDesignation = (TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtDesg");

con.Open();

SqlCommand cmd = new SqlCommand("update Employee_Details set City='" + txtcity.Text + "',Designation='" + txtDesignation.Text + "' where UserId=" + userid, con);

cmd.ExecuteNonQuery();

con.Close();

lblresult.ForeColor = Color.Green;

lblresult.Text = username + " Details Updated successfully";

gvDetails.EditIndex = -1;

BindEmployeeDetails();

}

protected void gvDetails_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

{

gvDetails.EditIndex = -1;

BindEmployeeDetails();

}

protected void gvDetails_RowDeleting(object sender, GridViewDeleteEventArgs e)

{

int userid = Convert.ToInt32(gvDetails.DataKeys[e.RowIndex].Values["UserId"].ToString());

string username = gvDetails.DataKeys[e.RowIndex].Values["UserName"].ToString();

con.Open();

SqlCommand cmd = new SqlCommand("delete from Employee_Details where UserId=" + userid, con);

int result = cmd.ExecuteNonQuery();

con.Close();

if (result == 1)

{

BindEmployeeDetails();

lblresult.ForeColor = Color.Red;

lblresult.Text = username + " details deleted successfully";

}

protected void gvDetails_RowCommand(object sender, GridViewCommandEventArgs e)

{

if(e.CommandName.Equals("AddNew"))

{

TextBox txtUsrname = (TextBox)gvDetails.FooterRow.FindControl("txtftrusrname");

TextBox txtCity = (TextBox)gvDetails.FooterRow.FindControl("txtftrcity");

TextBox txtDesgnation = (TextBox) gvDetails.FooterRow.FindControl("txtftrDesignation");

con.Open();

SqlCommand cmd =

new SqlCommand(

"insert into Employee_Details(UserName,City,Designation) values('" + txtUsrname.Text + "','" +

txtCity.Text + "','" + txtDesgnation.Text + "')", con);

int result= cmd.ExecuteNonQuery();

con.Close();

if(result==1)

{

BindEmployeeDetails();

lblresult.ForeColor = Color.Green;

lblresult.Text = txtUsrname.Text + " Details inserted successfully";

}

else

{

lblresult.ForeColor = Color.Red;

lblresult.Text = txtUsrname.Text + " Details not inserted";

}

Bill said...: Excellent! It was so good I'm now using it! Thank you for sharing!; March 2, 2012 at 10:22 AM
Bill said...: If you having a problem at con.open() it is because there is no database. Right click on App_Data, and add new item . SQL Server Database and name it anything you want. Add a table, and add 4 columns, called
UserID int (make this primary key and also make it auto increment by adjusting the column properties to Identity Specification to YES)
and three others called UserName, City, Designation (all strings or nchar(40))
Save this table as Employee_Details. Right click on the database and select properties. Copy the whole connection string and paste into line #17 where the string starts with Data Source=. When you start the sample it should run!; March 2, 2012 at 10:34 AM

wen i enter data in the o/p that data store in the table using update query..... how can i solve???give me code....; August 10, 2012 at 9:48 AM
Unknown said...: Hi,
your coding is very useful. I made some modification in the above coding I feel one difficulty. That is I added a button or a dropdownlist with autopostback set as true. Initially the gridview is empty and thus "No Records Found" message is shown. When I select any item from the dropdownlist or button click an empty row with Item Template controls(edit and delete) at 1st row position by the gridview.
please give me a solution for avoiding this auto post back problem.

Unknown said...: I am having trouble whle following this example. I have a dropdownlist that populates with the column names of the table and a text box. I sucessfully search for records that only match the type input and rebind with no issues. Now if I try to use the edit or delete buttons the page crashes with the error:

Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

all my research points to the IsPostback but if that were the case my postback from my search field wouldn't work either. Help; March 8, 2013 at 5:11 AM

I even tried just storing them in a string variable, no luck.; March 8, 2013 at 8:07 AM
Anonymous said...: @Sam

for using allow paging, set the following properties in gridview,

AllowPaging ="true" PageSize ="3" OnPageIndexChanging="gvDetails_PageIndexChanging"

and also add the following code,

protected void gvDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{

gvDetails.PageIndex = e.NewPageIndex;

BindEmployeeDetails();

}

hope this will help you..
