解决方案

如果唯一的可能性是Yes和No，我会考虑使用CheckBox而不是文本进行输入.

您可以使用 JavaScript [ http://kottawadumi.blogspot.com/2010/05/how-to- validate-textbox-using.html [ ^ ]

使用单选按钮或复选框.因为您可以选择是"或否"，所以比文本框"更好.

Hi All,

I am new to DotNet.

In a webpage I have one Textbox name as Status.I need to restrict the user to enter only Yes or No in the Textbox.

Help me out from this

Alternatively.

I can do with dropdown but there should be only textbox.
Thanks in Advance.

解决方案

If the only possibilities are Yes and No, I would consider using a CheckBox rather than text for input.

You can use Javascript[^] for validating your textbox. There are plenty of examples on the Internet about this.

[Update]
The link below is a good example of validating a textbox using Javascript.

Use Radio Button or Check Box. Because you have the option as Yes or No. that will be better instead of Textbox.
