I have an asp textbox control, now using regular expression I want to validate that control, which should contain 9 characters where first 2 are letters and then 6 numbers and then 1 letter. Any help would be appreciated.

If I know my Regex, you could use this: ^[a-zA-Z]{2}[\d]{6}[a-zA-Z]{1}$.
如果我知道我的正则表达式，你可以使用它：^ [a-zA-Z] {2} [\ d] {6} [a-zA-Z] {1} $。
(The {1} at the end isn't needed, but I though it looks good...)
（不需要最后的{1}，但我看起来不错......）
How you check that is up to you. You can do this in code-behind (since you're using asp.net) or JS.
你如何检查这取决于你。您可以在代码隐藏（因为您使用的是asp.net）或JS中执行此操作。
EDIT: Should also work with a ValidationExpression.
编辑：也应该使用ValidationExpression。
Here's a sample of this in use:
以下是使用中的示例：
<asp:TextBox ID="TB1" runat="server" />
<asp:RegularExpressionValidator ID="validator" runat="server" ControlToValidate="TB1" ErrorMessage="2 letters, 6 digits and a letter, hotshot!" ValidationExpression="^[a-zA-Z]{2}[\d]{6}[a-zA-Z]{1}$" />
