<a href> tag in TextBox in GridView

Question

This is not a pretty application by any stretch. It's only meant for a select few to use in the office and does not require street appeal. With that said...

I have a gridview with the following template column:

<asp:TemplateField HeaderStyle-HorizontalAlign="Left"> 
<ItemTemplate> 
<asp:Label ID="lblAction" runat="server" Text='<%#(Eval("Action"))%>' 
       ToolTip="Action to be Taken"></asp:Label> 
     </ItemTemplate> 
     <EditItemTemplate> 
     <asp:TextBox ID="txtAction" runat="server" 
       TextMode="MultiLine" Width="450px" Height="100px" ValidationGroup="UpdateFU" 
        Text='<%#Eval("Action")%>' 
        CssClass="RequiredText" ToolTip="Follow-Up Action"> 
       </asp:TextBox> 
       <asp:RequiredFieldValidator ID="rfv_txtAction" runat="server" 
       ControlToValidate="txtAction" ErrorMessage="FollowUp Action is Required" 
        Text="*" ValidationGroup="UpdateFU"> 
       </asp:RequiredFieldValidator> 
</EditItemTemplate> 
<FooterTemplate> 
    <asp:TextBox ID="txtAction" runat="server" 
TextMode="MultiLine" Width="250px" 
ValidationGroup="UpdateFU" 
CssClass="RequiredText" 
ToolTip="Follow-Up Action"> 
</asp:TextBox> 
<asp:RequiredFieldValidator ID="rfv_txtAction" runat="server" 
ControlToValidate="txtAction" ErrorMessage="FollowUp Action is Required" 
Text="*" ValidationGroup="AddFU"> 
</asp:RequiredFieldValidator> 
</FooterTemplate> 
</asp:TemplateField> 

For the example that is causing me trouble, the data in the field that is bound to this column is: **Testing with a link. <a href="http://www.google.com">Google</a>**

The label in the ItemTemplate displays as I expect it to. The regular text is not hyperlinked and the hyperlink text is. Please see the included image: ItemTemplate

내 행이 편집 모드에있을 때 텍스트 상자에도 의심되는대로 표시됩니다. 포함 된 이미지를 참조하십시오. EditItemTemplate

레코드를 저장하거나 취소하려고하면 명령 단추가 클릭되었음을 gridview에서 인식하지 못합니다. 그것은 단지 거기에 앉아있다. 태그를 참조하는 텍스트 (예 : **Testing with a link.**에서 제외)를 제거하면 멋지게 작동합니다. 유일한 문제는 내 링크가있는 텍스트 상자에 텍스트를 저장할 수 없다는 것입니다.

도움을 주시면 대단히 감사하겠습니다.

여러분의 GridView에서 UpdatePanel을 사용하고 있다고 생각합니다. 그래서 브라우저 콘솔을 확인하지 않으면 예외가 누락됩니다.
