推荐答案

您是否尝试过在GridView中添加正则表达式验证器或自定义验证器.甚至Javascript也可以帮助您达到要求.见下文:

Have you tried adding regex validators or custom validators in the gridview. Even Javascript can help you achieve your requirement. See below:

<script type="text/javascript" language=javascript>
function keyDownNumber()
{
    var key;
    if(navigator.appName == 'Microsoft Internet Explorer')
        key = event.keyCode;
    else
        key = event.which

    if ( !(key >= 48 && key <= 57) && key != 8 && key != 46 && key != 36 && key != 37)
    {
        event.returnValue = false;
    }
}
</script>

<Columns>
<asp:templatefield headertext="Days">
        <itemtemplate>
          <asp:TextBox id="Days" text='<% # eval("Days") %>' runat="server"

            onkeypress="keyDownNumber()" >
           </asp:TextBox>
       </itemtemplate>
 </asp:templatefield>
</Columns>

对于DataGridView，您可以参考以下链接:

For DataGridView you can refer following links:
