HtmlEncode not working in asp.net - asp.net

Question

I having a problem to make HtmlEncode work properly inside a GridView in ASP.Net. Basically I'm using TemplateField to toggle ItemTemplate and EditItemTemplate to have data entry on the GridView itself. I'm looking for some resource in how I can encode Eval and Bind method in ASP.Net but all of them not work in my end.
here's my code below:
<div id="dvShowContent" runat="server" style="text-align: center">
<asp:GridView ID="dgvSortKey" runat="server" AllowSorting="True" OnRowDataBound="gv_drb"
AutoGenerateColumns="False" AllowPaging="True" BackColor="White" BorderColor="#336666"
BorderStyle="Double" BorderWidth="3px" CellPadding="4" GridLines="Horizontal"
Height="73px" AutoGenerateEditButton="True" OnRowEditing="dgvSortKey_RowEditing"
OnRowUpdating="dgvSortKey_RowUpdating" OnRowCancelingEdit="dgvSortKey_RowCancelingEdit"
OnSelectedIndexChanging="dgvSortKey_SelectedIndexChanging" OnPageIndexChanged="dgvSortKey_PageIndexChanged"
OnPageIndexChanging="dgvSortKey_PageIndexChanging" OnRowCommand="dgvSortKey_RowCommand"
OnRowDeleted="dgvSortKey_RowDeleted" OnRowUpdated="dgvSortKey_RowUpdated" Width="561px"
PageSize="15" DataKeyNames="KeyCode,KeyDescription">
<FooterStyle BackColor="White" ForeColor="#333333" />
<RowStyle BackColor="White" ForeColor="#333333" />
<PagerStyle BackColor="#336666" ForeColor="White" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#339966" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#336666" Font-Bold="True" ForeColor="White" HorizontalAlign="Center" />
<AlternatingRowStyle BackColor="LightCyan" />
<Columns>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:LinkButton ID="lnkdelete" runat="server" OnClick="lnkdelete_Click">Delete</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Instruction Key Code">
<ItemTemplate>
<asp:Label ID="lblValKeyCode" runat="server" Text='<%# Server.HtmlEncode((string)Eval("KeyCode")) %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtValKeyCode" runat="server" Text='<%#Bind("KeyCode") %>' MaxLength="10"></asp:TextBox>
<%--<asp:TextBox ID="txtValKeyCode" runat="server" Text='<%#System.Web.HttpUtility.HtmlEncode(Eval("KeyCode").ToString()) %>' MaxLength="10"></asp:TextBox>--%>
</EditItemTemplate>
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" CssClass="GvBorderGreen" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<asp:Label ID="lblValKeyDescription" runat="server" Text='<%# Server.HtmlEncode((string)Eval("KeyDescription")) %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtValKeyDescription" runat="server" Text='<%#Bind("KeyDescription") %>'
MaxLength="10"></asp:TextBox>
<%--<asp:TextBox ID="txtValKeyDescription" runat="server" Text='<%#System.Web.HttpUtility.HtmlEncode(Eval("KeyDescription").ToString()) %>'
Width="300" MaxLength="20"></asp:TextBox>--%>
</EditItemTemplate>
<ItemStyle CssClass="GvBorderGreen" />
</asp:TemplateField>
<%--<asp:BoundField DataField="KeyCode" HeaderText="Instruction Key Code" HtmlEncode="true" />
<asp:BoundField DataField="KeyDescription" HeaderText="Description" HtmlEncode="true" />--%>
</Columns>
</asp:GridView>
</div>
Please help me to solve this problem.

As Waqar suggests the answer is in the link he provided - to make this more clear you need to change this line:
<asp:TextBox ID="txtValKeyCode" runat="server" Text='<%#Bind("KeyCode") %>' MaxLength="10"></asp:TextBox>
To this:
<asp:TextBox ID="txtValKeyCode" runat="server" Text='<%#System.Web.HttpUtility.HtmlEncode((string)Eval("KeyCode")) %>' MaxLength="10"></asp:TextBox>
