如何通过链接按钮发回信息 [英] how to do post back by link button

问题描述

我有一些验证标注控件，我有三个按钮，可以进行编辑，更新，取消

但是每当验证控件无效时，取消按钮均不起作用

我已经用过

i have some validation callout controls i have three buttons edit, update,cancel

but cancel button is not working whenever any of validation control is invalid

i have already used

function returnTrue()
{
return true;
}

<asp:linkbutton id="cancel" runat="server" onclientclick="return returnTrue(); true;">

推荐答案

代码问题.

1)没有设置OnClick属性.

2)删除onclientclick中多余的true;.您已经从returnTrue()函数返回true.如下更改代码.

Couple of issues with your code.

1) No OnClick Property set.

2) Remove that extra true; in your onclientclick. You are already returning true from your returnTrue() function. Change your code as below.

<asp:linkbutton id="cancel" runat="server" onclientclick="return returnTrue();" onclick="cancel_Click" >

3)如果您在上面注意到我已将cancel_Click事件分配给OnClick，则应在您的代码隐藏区中定义它.

3) If you noticed above I have assigned cancel_Click event to OnClick, then it should be defined in your code-behind.

void cancel_Click(object sender, System.EventArgs e)
{
  //Your Button Clcik code here.

}
