Answer 1

btn2.Attributes.Add("onclick", "javascript:return confirm('Are you sure you want to add this    estimate data??')"); 

Answer 2

您可以使用以下代码：

btn2.Attributes.Add("onclick", "return confirm('Are you sure you want to add this estimate data?');")

Answer 3

您可以将 ajaxcotoroll 工具包引用添加到您的网站，并为每个按钮动态创建确认

Button btn2 = new Button();
btn.ID="buttonID";
ConfirmButtonExtender confirm = new ConfirmButtonExtender();
confirm.TargetControlID = "buttonID";
confirm.ConfirmText="Are you sure you want to add this    estimate data??'";

Answer 4

您也可以使用以下代码：-

btn2.Attributes["onClick"] = "return confirm('Are you sure you want to add this   estimate data??');"

Answer 5

试试这个鳕鱼：

 Button yourbtnid = new Button();
 yourbtnid.ID="Button1";
 ConfirmButtonExtender conf = new ConfirmButtonExtender();
 conf.TargetControlID = "Button1";
 conf.ConfirmText="Are you sure you want to add this    estimate data??'";

这是使用 Ajaxcontroll 调用..

或者

Button yourbtnid = new Button();
yourbtnid.Attributes.Add(
     "OnClientClick", 
     "return confirm('Are you sure you want to add this    estimate data??');");
