onclick on an image

[jimberger]

Hello,

I am trying to create a image that has an onlick event that runs my ASP.NET function submit_search. When a place an onclick on an image it tries to look for a javascript function called submit_search. I've also tried using ASP:Imagebutton but I can't get this to work either?

any ideas anyone?
thanks

jim

There are no handlers of the control Image. You can only define the ImageUrl whenever you want, the alignment etc..

Instead, delete it and drag an ImageButton control. This has event handlers such as onClick()

Session["sDay"] = startday.SelectedValue;
Session["sMonth"] = startmonth.SelectedValue;


Server.Transfer("results.aspx");


but the page dosen't transfer to results.aspx

any ideas?

In the design view double click the image button and add there the code. The default hendler is the _onClick event.

You messed up javascript functions and asp.net function.

In javascript:
<script language=javascript type=text/java>
function Submit_Search(// arguments ?)
{
//
}
</script>

To call this you add to the button or whatever (html code) ... onclick="Submit_Search();"

In ASP.NET, when using VB.NET, your code do not return something so it is a Sub (Public, shared, private ...)

Else it is a function:
<ScopeType> Function NameOfFunction('args ?) As <TypeReturned>
' one return must be executed
End Function


Sub Submit_Search() 'Private
Session["sDay"] = startday.SelectedValue;
Session["sMonth"] = startmonth.SelectedValue;

Server.Transfer("results.aspx");
End Sub

Call it in the click event handler by just typing the sub's name
