[英]How can I dynamically create an ASP:Button that causes no postback inside an UpdatePanel?
I have a page some 2 ASP Tabs and with an UpdatePanel on the first tab. 我的页面上有2个ASP选项卡,第一个选项卡上带有UpdatePanel。 Inside the update panel (on page_load), I dynamically create a table that contains rows with cells for an image, some text, and an ASP:Button.
在更新面板中(在page_load上),我动态创建一个表,该表包含带有单元格的行,这些单元格包含图像,一些文本和一个ASP:Button。 I'd like the button, when clicked to switch tabs from the first to the second.
单击按钮以将选项卡从第一个切换到第二个时,我想要按钮。 Instead, all it does is refresh the updatepanel it resides in. How can I stop it from behaving that way?
相反,它所做的只是刷新它所驻留的updatepanel。如何阻止这种行为? How do I get it to perform a function of my own design, instead of posting?
我如何获得它来执行自己设计的功能,而不是发布?
Thank you, 谢谢,
You can add javascript click event and stop it to do post back by returning false; 您可以添加javascript click事件,并通过返回false来使其停止发回;
In Code behind, where you add button dynamically. 在后面的代码中,您可以在其中动态添加按钮。
btnChangeTab.Attributes.Add("onclick", "return YourJavascriptFunction();");
In Client side. 在客户端。
<script type="text/javascript">
function YourJavascriptFunction()
{
//Your javascript code here
return false; //the will stop from postback
}
</script>
