Editable data grid view throwing exception

I am trying to create an editable DataGridView and I have enabled the "AutoGenerateEditButton" to true but when i click the edit on the page it throws this excetion

"System.Web.HttpException: The GridView 'GridView1' fired event RowEditing which wasn't handled."

Any ideas why? The code that I am using is below

I would also like to know how i would be able to update the edited value into the datatable so its updated.

Html

<asp:GridView ID="GridView1" runat="server" AutoGenerateEditButton="True" Width="1060px">
</asp:GridView>

C# (Code Behind)

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        add();
    }
}

private void add()
{
     DataTable dt = new DataTable();
     dt.Columns.Add("ab", typeof(string));
     dt.Columns.Add("ac", typeof(string));
     dt.Columns.Add("av", typeof(string));
     dt.Columns.Add("ax", typeof(string));
     DataRow row = dt.NewRow();
     row["ac"] = "sndasbfb";
     row["av"] = "sndasbfb";
     row["av"] = "sndasbfb";
     row["ax"] = "sndasbfb";
     dt.Rows.Add(row);
     GridView1.DataSource = dt;
     GridView1.DataBind();
}

Add a onrowediting event..

<asp:GridView ID="GridView1" runat="server" AutoGenerateEditButton="True" 
                    Width="1060px" Onrowediting="Gridview_rowediting">

                </asp:GridView>


protected void Gridview_rowediting(object sender, GridViewEditEventArgs e)
{

}

TO update the gridview add onrowupdating event..

protected void Gridview_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
   update();

}
private void update()
{
 DataTable dt = new DataTable();
 dt.Columns.Add("ab", typeof(string));
 dt.Columns.Add("ac", typeof(string));
 dt.Columns.Add("av", typeof(string));
 dt.Columns.Add("ax", typeof(string));
 DataRow row = dt.NewRow();
 row["ac"] = "newvalue";
 row["av"] = "newvalue";
 row["av"] = "newvalue";
 row["ax"] = "newvalue";
 dt.Rows.Add(row);
 GridView1.DataSource = dt;
 GridView1.DataBind();
 }

As the error suggesting you have not handled the OnRowEditing="GridViewEditEventHandler" event.
Which get triggered if the default edit link is click on the gridview


You will need to handle OnRowEditing as follows

<asp:GridView ID="GridView1" runat="server" OnRowEditing="GridView1_RowEditing"
         AutoGenerateEditButton="True" Width="1060px">
</asp:GridView>

and In the code behind you will have to handle this event as follow

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
  //  GridView1.SelectedIndex = e.NewEditIndex;
      //do your stuff here
    add();
}

You need to add an Event for the RowEditing

Look here for further information: http://forums.asp.net/p/1144799/1850877.aspx#1850877

gvSalesEventSearch.RowEditing += new GridViewEditEventHandler(gvSalesEventSearch_RowEditing);

void gvSalesEventSearch_RowEditing(object sender, GridViewEditEventArgs e)
{

}
