推荐答案

您本可以尝试

You could have tried a Google search[^] first.

<asp:RegularExpressionValidator ID="regName" runat="server" ControlToValidate="txtYourControlId"
                      ValidationGroup="ValidGroup" Display="Dynamic" ValidationExpression="^[a-zA-Z'.\s]"
                      Text="Please enter alphabets only" />

使用此方法:ValidationExpression ="^ [a-zA-Z''.\ s]"

Use this : ValidationExpression="^[a-zA-Z''.\s]"

您可以使用正则表达式执行相同的操作:

you can use regular expression to do the same:

//use System.Text.RegularExpressions

if (Regex.IsMatch("^[a-zA-Z]", textBox1.Text))
   {
//assign error to label
          }
