我尝试使用脚本管理器打开模式
ScriptManager.RegisterStartupScript(this, GetType(), "YourUniqueScriptKey", " $('#MyModal').modal('show') ;", true);
我想在 pdf 下载后显示弹出模式。
解决方案
如果您的引导程序的 javescript 完整并包含到页面中，则必须这样做：
<script type="text/javascript">
function openModal() {
$('#myModal').modal('show');
}
</script>
.cs 代码
ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", openModal(), true);
如果这不起作用，请检查您的引导 javascript。
这段代码：
protected void btnSubmit_Click1(object sender, EventArgs e)
{
CancelBookingBal bal = new CancelBookingBal();
int BookingID = Convert.ToInt32(bid.Value);
int uId = Convert.ToInt32(uid);
int amount = 0;
if (bal.updateUser(BookingID, uId))
{
amount = UserBookingBal.getBookingAmt(BookingID);
ScriptManager.RegisterStartupScript(this, GetType(),
"YourUniqueScriptKey", " $('#MyModal').modal('show') ;",
true);
}
}
模态按钮单击确定
protected Modalbutton_onClick(object sender, EventArgs e)
{
BillDownloader(uId, BookingID, amount);//Provide parameter on top
}
在这之前：
Modalbutton_onClick
您已经检查该文件是否存在。如果文件存在与否，模式必须首先抛出一条消息。
