You are mixing server and client side code in the same event, it has to be separated:
您在同一个事件中混合服务器和客户端代码，它必须分开：
Script:
脚本：
function Confirm()
{
var record=confirm('Are you sure to proceed??');
if(record == 1)
{
return true;
}
else if(record == 0)
{
return false;
}
}
Markup:
标记：
<asp:Button ID="btnCopy" runat="server" Text="Copy" Enabled="false"
OnClick="btnCopy_Click" OnClientClick='return Confirm();' ValidationGroup="Copy" />
Code-behind:
代码隐藏：
public void btnCopy_Click(object sender, EventArgs e) {
if (Convert.ToInt32(hidId.Value) > 0) {
BindDataGrid();
}
}

You'll need to catch the response, for example:
您需要捕获响应，例如：
if (window.confirm)
{
//handle the OK
}
else
{
//handle the cancel
}
回答by Sam Sussman
Please show the code, but without seeing your code I would guess you are not returning the response?
请显示代码，但如果没有看到您的代码，我猜您没有返回响应？
<input type="button" onclick=" return confirm('is this right?'); ">

You can simply returnfrom the code or exit(0).
您可以简单地return从代码或exit(0).
function fillGrid()
{
if( confirm("....") )
{
//populate your grid
}
else
{
return;
}
//do anything after the grid is populated
//and exit the function
}

You are showing the confirm dialog in the codebehind of your button click, that wont stop the flow of your code.
您正在按钮单击的代码隐藏中显示确认对话框，这不会停止您的代码流。
You need to show the confirm dialogbox before do the postback
您需要在回发之前显示确认对话框
<asp:Button ID="btnCopy" runat="server" Text="Copy" Enabled="true" OnClientClick="return confirm('sure?');" ValidationGroup="Copy" />
