Set EnableEventValidation="false" right at the top in your Page directive:

<%@ Page EnableEventValidation="false" Language="C#"...

Just beware that setting this value to false can expose your website to security vulnerabilities.As an alternative, instead of setting EnableEventValidation="false" you can handle the grid views OnRowCommand:

.ASPX:

<asp:GridView ID="GridView1" runat="server" OnRowCommand="GridView1_RowCommand">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Button runat="server" Text="Approve" CommandName="Approve" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Code behind:

public partial class delete_me : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)//THIS IS IMPORTANT.GridView1_RowCommand will not fire unless you add this line
        {
            var p1 = new Person() { Name = "Person 1" };
            var p2 = new Person() { Name = "Person 2" };

            var list = new List<Person> { p1, p2 };
            GridView1.DataSource = list;
            GridView1.DataBind();
        }

    }

    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        System.Diagnostics.Debugger.Break();
    }
}

public class Person
{
    public string Name { get; set; }
}

You Just put on your gridview.

<asp:TemplateField>
                                <ItemTemplate>
                                    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click"/>
                                </ItemTemplate>
                            </asp:TemplateField>

Also put code behind

protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Redirect("WebForm1.aspx");
        }

Try!!!! it's working fine...

whats the difference sir? – Paolo Duhaylungsod May 28 '16 at 11:13 — Paolo Duhaylungsod, May 28 '16 at 11:13
