Solution 1

if you want to compare values of both textboxes then only you can use compare validator,

if you want to compare value,and length means you can use custom validator

below is gridview code

XML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Label ID="lbleno" Text='<%#Eval("eno") %>' runat="server"></asp:Label>
                    </ItemTemplate>

                </asp:TemplateField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:TextBox ID="txtename" Text='<%#Eval("ename") %>' runat="server"></asp:TextBox>
                    </ItemTemplate>

                </asp:TemplateField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:TextBox ID="txtename1" Text='<%#Eval("ename") %>' runat="server"></asp:TextBox>
                        <asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="ename,ename1 must match"
                            OnServerValidate="CustomValidator1_ServerValidate" ValidateEmptyText="true" ValidationGroup="txt"></asp:CustomValidator>
                    </ItemTemplate>

                </asp:TemplateField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Label ID="lblsal" Text='<%#Eval("salary") %>' runat="server"></asp:Label>
                    </ItemTemplate>

                </asp:TemplateField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="btnsubmit" runat="server" Text="Submit" ValidationGroup="txt" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

.cs page code

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            SqlConnection conn = new SqlConnection(your connection string);
            SqlDataAdapter da = new SqlDataAdapter("select * from tablename", conn);
            DataSet ds = new DataSet();
            da.Fill(ds);
            GridView1.DataSource = ds.Tables[0];
            GridView1.DataBind();
        }
    }
    protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
    {
        CustomValidator cv=(CustomValidator)source;
        GridViewRow gvr = (GridViewRow)cv.NamingContainer;
        TextBox txt1 = (TextBox)gvr.FindControl("txtename");
        TextBox txt2= (TextBox)gvr.FindControl("txtename1"); 
        if(txt1.Text==txt2.Text)
        {
            args.IsValid=true;     
        }
        else
            args.IsValid=false;
    }
