如何使用数据库检查文本框中的每个条目
我希望文本框中的每个条目都应该与table一起检查。有没有可能使用asp.net或ajax中的任何工具。
i在代码中尝试过,但是它需要一些时间来检查。
i想要为这个文本框设置验证。
谢谢,

你可以在Textbox的TextChanged事件中处理它。类似下面的代码。
You can handle it inside the TextChanged event of the Textbox . Something like the below code .
<asp:TextBox ID="TextBox1" runat="server" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
Code Behind:
Code Behind :
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
//Do your input checking with a DB Call
}
如果要在Clientside / Ajax中检查相同内容,可以查看本文作为参考
