Check Box Event onCheckChanged : Event is not firing

Question

I am using a CheckBox like this:

ASPX

<asp:CheckBox ID="cbCode" runat="server" OnCheckedChanged="cbCode_CheckedChanged" />

C#

protected void cbCode_CheckedChanged(object sender, EventArgs e)
{
    if (!Convert.ToBoolean(cbCode.Checked))
    {

    }
    else
    {

    }
}

The event is not firing and I'm unable to find out what is missing.

Answer 1

您需要在复选框上使用AutoPostBack="True" 。

Answer 2

您可以在updatepanel的内容下方为复选框选中更改添加触发器。
