I have a small working application in ASP.NET and C#, and I would like to add some JavaScript code to it.
I know that, for example, I can use the Confirm button and then do something on Yes or No.
I would like to call some of the functions I have in the code-behind, depending on the answer to the Confirm button.
How do I go about this?
Simple.
Put a hidden div on your .aspx page that contains button triggers to your methods:
<div style="display: none">
<asp:Button ID="TriggerMethod1" runat="server" />
</div>
In your JavaScript code, in the confirm part of your code, simply do:
__doPostBack('TriggerMethod1', '');
And in your code-behind, handle up that button click to call Method1.
$("#TriggerMethod1").click();.
I would create an ASHX handler file and post back to the hander using jQuery ajax methods.
See an article on this here:
To call a server-side method on a client-side event you need to do the following:
Create the server-side method:
void DoSomething(...) { ... }
Implement the System.Web.UI.IPostBackEventHandler.RaisePostBackEvent which take one string argument (you can assign the name to the value of this argument).:
public void RaisePostBackEvent(string eventArgument)
{
DoSomething(...);
}
Write a script to trigger a post back:
function TriggerPostBack(control, arg){
__doPostBack(control, arg);
}
Call the PostBack trigger function when needed:
<a .... onclick="TriggerPostBack('control', 'arg')" .. />
