Introduction:

If you are going to use DataGrid then here we need to edit, update, delete data in DataGrid. Suppose in that table which data you are using in DataGrid, there  are so many records that on one page all of the records can not come, then here paging plays an important role to show our data in a manner in DataGrid.

So in this article I am going to show how to edit, delete and update data in DataGrid and paging too.

This is the aspx code: 

From Here we can design our web form. We use a DataGrid on webForm. Here we set all the property as we have to perform the operation with in DataGrid.

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default"Debug="true" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>

    <form id="form1" runat="server">

    <div>

       <asp:DataGrid ID="gridedit" runat="server" DataKeyField="id" BorderStyle="Ridge"GridLines="None" BorderWidth="2px" BorderColor="White" BackColor="White" CellPadding= "3" CellSpacing="1" AllowSorting="True" PagerStyle- HorizontalAlign= "Center" HorizontalAlign="Left"OnEditCommand="editgrid_click" OnCancelCommand= "gridcancel_click" OnPageIndexChanged="gridedit_PageIndexChanged"OnUpdateCommand="updategrid_UpdateCommand" Height="267px" PageSize=5AllowPaging="true" OnDeleteCommand= "gridedit_DeleteCommand"AutoGenerateColumns="false" Width="50%">

        <HeaderStyle Font-Bold="True" ForeColor="#FFFFFF"

                  BackColor="#A53A6A"></HeaderStyle>

       <FooterStyle BackColor="beige" />

       <PagerStyle Font-Bold="true" Mode=NumericPages Font-Underline="true"/>

 

      <Columns>

 

           <asp:BoundColumn DataField=id HeaderText="ID">

          <ItemStyle BackColor="graytext" />

          <HeaderStyle BackColor="graytext" />

          </asp:BoundColumn>

        

          <asp:BoundColumn DataField=name HeaderText="Name">

          <ItemStyle BackColor=GhostWhite />

          </asp:BoundColumn>

                 

          <asp:BoundColumn DataField=F_name HeaderText="F_Name">

          <ItemStyle BackColor=GhostWhite />

          </asp:BoundColumn>

        

          <asp:BoundColumn DataField=l_name HeaderText="L_Name">

          <ItemStyle BackColor=GhostWhite />

          </asp:BoundColumn>

         

          <asp:BoundColumn DataField=City HeaderText="City">

          <ItemStyle BackColor=GhostWhite />

          </asp:BoundColumn>

         

          <asp:BoundColumn DataField=State HeaderText="State">

          <ItemStyle BackColor=GhostWhite />

          </asp:BoundColumn>

         

          <asp:EditCommandColumn CancelText="Cancel" EditText="Edit" 

                         UpdateText="Update" HeaderText="Edit">

          <ItemStyle BackColor=GhostWhite />

          </asp:EditCommandColumn>

         

          <asp:ButtonColumn CommandName="Delete" HeaderText="Delete" Text="Delete">

          <ItemStyle BackColor=GhostWhite />

          </asp:ButtonColumn>

 

      </Columns>

   </asp:DataGrid>

  </div>

</form>

</body>

</html>
 

With this aspx code our web form will become look like as:

This is the source code:

    Protected Sub Page_Load(ByVal sender As ObjectByVal e As EventArgs) 

        If Not Page.IsPostBack Then

            Binddata()

        End If

    End Sub
 

    ' Define the Edit Command 
 

    Public Sub editgrid_click(ByVal sender As ObjectByVal e As DataGridCommandEventArgs) 

        gridedit.EditItemIndex = e.Item.ItemIndex 

        Binddata() 

    End Sub
 

    ' Define the Cancel Command 
 

    Public Sub gridcancel_click(ByVal sender As ObjectByVal e As DataGridCommandEventArgs)
 

        gridedit.EditItemIndex = -1 

        Binddata() 

    End Sub
 

    'Here we Bind the data 
 

    Public Sub Binddata() 

        con = New SqlConnection(ConfigurationSettings.AppSettings("connect")) 

        cmd.CommandText = "select * from record" 

        cmd.Connection = con 

        da = New SqlDataAdapter(cmd) 

        da.Fill(ds) 

        con.Open() 

        cmd.ExecuteNonQuery() 

        gridedit.DataSource = ds 

        gridedit.DataBind() 

        con.Close() 

    End Sub
 

    'Update Command Defination 
 

    Protected Sub updategrid_UpdateCommand(ByVal source As ObjectByVal e AsDataGridCommandEventArgs) 

        con = New SqlConnection(ConfigurationSettings.AppSettings("connect")) 

        cmd.CommandText = "Update record set name=@name ,F_name=@F_Name," & Chr(13) &""l_name = l_name

    End Sub

End Class  
 

When we run our project then it will look as:
