# Bind ID dynamically on a textbox

I have

<[asp](https://www.mindstick.com/articles/751/introduction-to-asp-dot-net-mvc):[TextBox](https://www.mindstick.com/forum/12714/dynamic-textbox-in-gridview) ID="txtBidAmmount<%#Eval("id") %>" Width="250" runat="[server](https://www.mindstick.com/articles/43769/what-is-serverless-architecture-is-it-worth-switching-over)"></asp:TextBox>

That wouldn't work and I have read some [options](https://www.mindstick.com/articles/43878/making-the-best-use-of-the-options-trade-ideas) that I have to [replace](https://yourviews.mindstick.com/view/81330/cow-antibody-research-in-usa-a-step-ahead-to-replace-plasma-therapy) the " with ', so I did:

<asp:TextBox ID='txtBidAmmount<%#Eval("id") %>' Width="250" runat="server"></asp:TextBox>

But I get:

[Parser](https://www.mindstick.com/articles/742/xml-parser-in-php) [Error Message](https://www.mindstick.com/forum/23174/error-message-the-page-you-are-requesting-cannot-be-served-because-of-the-extension-configuration): 'txtBidAmmount<%#Eval("id") %>' is not a valid identifier.

```
<asp:GridView ID="EmployeesNoSuffix" runat="server"
   
AutoGenerateColumns="false" ClientIDMode="Predictable"><Columns>   
<asp:TemplateField HeaderText="ID">        
<ItemTemplate>             
<asp:Label ID="EmployeeID" runat="server"
Text='<%# Eval("ID") %>' />        
</ItemTemplate>    </asp:TemplateField>   
<asp:TemplateField HeaderText="Name">        
<ItemTemplate>             
<asp:Label ID="EmployeeName"       
runat="server" Text='<%# Eval("Name") %>'
/>        
</ItemTemplate>   
</asp:TemplateField></Columns></asp:GridView>
```

```
<table id="EmployeesNoSuffix" style="border-collapse: collapse"

try this

ID='<%# "txtBidAmmount" + eval("id") %>'

OR

ID='<%# Eval("id", "txtBidAmmount {0}") %>'
