<p>I want to make custom paging in GridView in ASP.Net, my data source is a object data.
I checked the web to find any code for this and found one which is not working for me. can any one please help me in solving this.</p>

<pre><code>  protected void invoiceReportsgridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        if (sender != null)
        {
            displayInvListgridView.PageIndex = e.NewPageIndex;
            displayInvListgridView.EditIndex = -1;
            displayInvListgridView.SelectedIndex = -1;
        }
    }

    protected void GridView_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Pager)
        {
            CustomizePageBar(e);
        }
    }

    void ProductsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
    {
        // If multiple buttons are used in a GridView control, use the
        // CommandName property to determine which button was clicked.
        if (e.CommandName == "Add")
        {
            // Convert the row index stored in the CommandArgument
            // property to an Integer.
            int index = Convert.ToInt32(e.CommandArgument);

            // Retrieve the row that contains the button clicked 
            // by the user from the Rows collection.
            GridViewRow row = displayInvListgridView.Rows[index];

            // Create a new ListItem object for the product in the row.     
            ListItem item = new ListItem();
            item.Text = Server.HtmlDecode(row.Cells[1].Text);

            // If the product is not already in the ListBox, add the ListItem 
            // object to the Items collection of the ListBox control. 
            //if (!displayInvListgridView.Items.Contains(item))
            //{
