如何在ASP.NET C＃中向按钮动态添加AutoPostBack = true

Question

I have the following code. My question is how can I dynamically add the autopostback property to the button?

Button button = new Button();
button.ID = "Button" + i;
button.Text = "Save";
button.Click += SaveButton_Click;
PlaceHolder1.Controls.Add(button);

Something like this button.autoPostBack = true;

Answer 1

By default an asp.net button control has AutoPostBack property equal to true . Though this property doesn't appear in button properties. If a Click event attached to a button , it will always do a server-trip .

As a side note! if you want that you button don't do a server-trip then you can disable its AutoPostBack property by removing its Click event and you could add OnClientClick event to run client-side code

<asp:Button ID="Button1" runat="server" OnClientClick="myJSfunction(); return false" Text="Button" />

You can use Attributes.Add in button. ie

button.Attributes.Add("AutoPostback","true");
