tab happens by default .. setting focus when user clicks on left and right arrow needs to be coded using javascript .. but it would not be user friendly .. imagine a user trying to move within a textbox by hitting the right arrow key and suddenly he is moved to the next control .. that would not be helpful ... why would you want this functionality?

My gridview is populated with the below:
    private void BindGrid()
    {
        int listMAX = 10;
        List<_MyDataClassObject> items = new List<_MyDataClassObject>(listMAX);
        for (int i = 0; i < listMAX; i++)
        {
            _MyDataClassObject c = new _MyDataClassObject();
            c.SiteCode = (int)Session["SiteCode"];
            c.OfficeNumber = (int)Session["OfficeID"];
            c.Location = (string)Session["Location"];
            c.DM_Validated = false;
            c.ToothNum = "";
            c.Surface = "";
            c.Quad = "";

            items.Add(c);
        }
        GridView1.DataSource = items;
        GridView1.DataBind();
    }

And here's the gridview layout:
       <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="2"
            ForeColor="#333333" GridLines="None" CellSpacing="1" OnRowCreated="GridView_Merge_Header_RowCreated" OnRowEditing="GridView1_RowEditing">
            <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
            <Columns>
                <asp:CommandField ShowEditButton="True" HeaderText="Row" />
                <asp:TemplateField HeaderText="Chk" HeaderStyle-CssClass="newhdr">
                    <ItemTemplate>
                        <asp:CheckBox ID="chkValidated" runat="server" Checked='<%# Bind("DM_Validated") %>'
                            Width="5px" TabIndex="0" Enabled="false"></asp:CheckBox>
                    </ItemTemplate>
.....

How can I make the Edit command work?  Right now as I test it with the below event:
   protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        TextBox txtbox = (TextBox)GridView1.Rows[e.NewEditIndex].Cells[3].FindControl("txtTranDate");
        txtbox.Text = GridView1.Rows[e.NewEditIndex].RowState.ToString();
        txtbox.Focus();
    }

txtbox.Text  displays "Normal".
Please help.
Thanks.

Sorry, is it still related to the same question or is this another one because I did not quite understand what you mean here .. I can say you cannot set focus the way you have done it in your code .. you will need to render a javascript to set the focus on the control

TextBox txtbox = (TextBox)GridView1.Rows[e.NewEditIndex].Cells[3].FindControl("txtTranDate");
page.registerclientscriptblock(me.gettype(), "setfocus", document.getElementById('" & txtbox.clientid & "').focus();")

I have a row of many textboxes and dropdowns to feed with that tabbing mechanism. So I figure if I can make the whole row as being edited then all the tabbing will be taken care of by RowState = Edit. Is that a possible solution? I am fraid that will work only with dataset as datasource and not with my current object list? Thanks.
