C#_控件——CheckBox，TextBox，RequiredFieldValidator

1.

            <asp:CheckBox ID="CheckBox2" runat="server" Text="你大爷" AutoPostBack="true" OnCheckedChanged="CheckBox2_CheckedChanged" />违法性质： <br /><br />
            <asp:TextBox ID="TextBox2" runat="server" TextMode="MultiLine" CausesValidation="false" ValidationGroup="submit" />
            <asp:RequiredFieldValidator ErrorMessage="不可以为空" ForeColor="Red" ControlToValidate="TextBox2" ValidationGroup="submit" runat="server" /><br /><br />
            <input id="Submit1" runat="server" type="submit" value="加入黑名单列表" validationgroup="submit" /><br /><br /><br /><br />

3.注意添加引用AspNet.ScriptManager.jQuery.dll，就可以使用ScriptManger

        protected void insert_ServerClick()
        {

        }
        protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
        {
            bool Ischecked = CheckBox2.Checked;
            ScriptManager.RegisterClientScriptBlock(this.CheckBox2,this.GetType(), "KKK","alert(\"nimei\")",true);
        }
