This article will give you an overview of how to use an asp:GridView completely, and how to use RowEditing, RowUpdating, RowDeleting, RowCommand, RowDataBound, RowCancelingEdit, and Pagination in a DataGrid. From this article, you will have a clear view of the GridView data insert, delete, and update operations.


GridView is a very popular control in ASP.NET, and for website development, it is a very important control. This control is especially important for CRUD operations.

Using the code

Make two tables in a database: Contact and ContactType. This is just an example of how we shall add, edit, and delete data in a GridView. I have also used a textbox, a drop down list, and a checkbox which we use in the case of data add, delete, and update.

Step by step

Take a web project, go to an .aspx page, for example, Default.aspx, and add an ASP.NET GridView:

<asp:GridView ID="grdContact" runat="server" 
 AutoGenerateColumns="False" DataKeyNames="Id, Type" 
 OnRowUpdating="grdContact_RowUpdating" ShowFooter="True" 

This is the GridView with all the necessary properties enabled and the events called.

For every column of the GridView, we need to make an <asp:TemplateField> field. I am using an <EditItemTemplate> to put the edit control, an <ItemTemplate> to bind data in a control, and a <FooterTemplate> to insert the control. Here is an example of a template field:

<asp:TemplateField HeaderText="Name" HeaderStyle-HorizontalAlign="Left"> 
    <asp:TextBox ID="txtName" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox> 
    <asp:TextBox ID="txtNewName" runat="server" ></asp:TextBox> 
    <asp:Label ID="lblName" runat="server" Text='<%# Bind("Name") %>'>


Let's take a look at the code for the GridView:

  1. Initialize the GridView: To fill data in the GridView, I have written a method named FillGrid() which takes data from a DataTable and shows it in the grid.
    public void FillGrid()
        ContactTableAdapter contact = new ContactTableAdapter();
        DataTable contacts = contact.GetData();
        if (contacts.Rows.Count > 0)
            grdContact.DataSource = contacts;
            grdContact.DataSource = contacts;
            int TotalColumns = grdContact.Rows[0].Cells.Count;
            grdContact.Rows[0].Cells.Add(new TableCell());
            grdContact.Rows[0].Cells[0].ColumnSpan = TotalColumns;
            grdContact.Rows[0].Cells[0].Text = "No Record Found";
  2. Fill dynamic values: There are two dropdownlist controls available in this example. One of the dropdownlists dynamically loads data from another table. In the RowDataBound event of the GridView control, insert the following code:
    protected void grdContact_RowDataBound(object sender, GridViewRowEventArgs e)
        ContactTypeTableAdapter contactType = new ContactTypeTableAdapter();
        DataTable contactTypes = contactType.GetData();
        if (e.Row.RowType == DataControlRowType.DataRow)
            Label lblType = (Label)e.Row.FindControl("lblType");
            if (lblType != null)
                int typeId = Convert.ToInt32(lblType.Text);
                lblType.Text = (string)contactType.GetTypeById(typeId);
            DropDownList cmbType = (DropDownList)e.Row.FindControl("cmbType");
            if (cmbType != null)
                cmbType.DataSource = contactTypes;
                cmbType.DataTextField = "TypeName";
                cmbType.DataValueField = "Id";
                cmbType.SelectedValue =
        if (e.Row.RowType == DataControlRowType.Footer)
            DropDownList cmbNewType = (DropDownList)e.Row.FindControl("cmbNewType");
            cmbNewType.DataSource = contactTypes;
  3. Insert data: I have initialized the GridView control with the DataTable, and also have some values filled in the footer dropdownlist, cmbNewType. Except Id, I have put FooterTemplate for every column because all the field are available. Clicking on "Insert" will enter data in your database table.
    protected void grdContact_RowCommand(object sender, GridViewCommandEventArgs e)
        ContactTableAdapter contact = new ContactTableAdapter();
        bool flag= false;
        if (e.CommandName.Equals("Insert"))
            TextBox txtNewName = 
            CheckBox chkNewActive = 
            DropDownList cmbNewType = 
            DropDownList ddlNewSex = 
            if (chkNewActive.Checked) flag = true; else flag = false;
            contact.Insert(txtNewName.Text, ddlNewSex.SelectedValue, 
                           cmbNewType.SelectedValue, flag);
  4. Update data: In the case of data update, we do the same things as the insert. In the case of insert, I always took the footer row, but in the case of update, I take the current RowIndex or the selected RowIndex. Click on Edit first, then call RowEditing, then the update and cancel options come.
    protected void grdContact_RowUpdating(object sender, GridViewUpdateEventArgs e)
        ContactTableAdapter contact = new ContactTableAdapter();
        bool flag = false;
        Label lblId = (Label)grdContact.Rows[e.RowIndex].FindControl("lblId");
        TextBox txtName = (TextBox)grdContact.Rows[e.RowIndex].FindControl("txtName");
        CheckBox chkActive = 
        DropDownList cmbType = 
        DropDownList ddlSex = 
        if (chkActive.Checked) flag = true; else flag = false;
        contact.Update(txtName.Text, ddlSex.SelectedValue, 
                       cmbType.SelectedValue, flag,Convert.ToInt32(lblId.Text));
        grdContact.EditIndex = -1;
    protected void grdContact_RowEditing(object sender, GridViewEditEventArgs e)
        grdContact.EditIndex = e.NewEditIndex;
    protected void grdContact_RowCancelingEdit(object sender, 
                              GridViewCancelEditEventArgs e)
        grdContact.EditIndex = -1;
  5. Deleting data: Now, you may need to delete data. The GridView calls RowDeleting for the delete event.
    protected void grdContact_RowDeleting(object sender, GridViewDeleteEventArgs e)
        ContactTableAdapter contact = new ContactTableAdapter();
        int id = Convert.ToInt32(grdContact.DataKeys[e.RowIndex].Values[0].ToString());

Points of Interest

So, now you have a DatGrid that is editable? Do you want to use CSS to give an excellent look of your grid? Just go to this link for a GridView CSS.

Happy coding Smile | :)


I was working on an admin panel in one of my projects, and saw that I needed many add, delete, and update operations for that panel. Now, I can easily solve that problem without a lot of programming by using an editable GridView. Smile | :)

Hello Ashrafur,

I found your example code very interesting, but found some limitations...

If I have a 1000 users DB and only would like to display 10 por page, how could I do that, without loading all the DB and then just stopping at the 10th row display? The idea is to use the LIMIT command in SQL, specifying the start and end of the selection.

Additionally, if I wanted to get the total rows, is it possible to do it without loading the whole data? Because it but by loading the same the Data:

ContactTableAdapter contact = new ContactTableAdapter();
DataTable contacts = contact.GetData();
double pages = Math.Ceiling((double)contacts.Rows.Count/10);
lblTotalPages.Text = System.Convert.ToString(pages);

That gets all the records downloaded from the DB, doesn't it?

Finally, I'm new to VS and C#, if I may ask, how do you get the XSD file generated if I wanted to add more columns to the update and insert queries? I added more columns to the Contact DB and had to modify the Insert and Update commands manually in the XSD file...

Thank you very much, Is it possible or I can only do that by switching to ADO.NET or Linq. Thumbs Up | :thumbsup:
