I have a page which contains a user control. When a user clicks on a submit button, I'd like to detect when elements in the user control have changed and popup a message box if changes have been detected to confirm if the user wants to save the changes.
Now I do it thus:
<form id="form1" onSubmit="return valForm1()" runat="server">
But I think that is not correct. Isn' t it?
it is right.
your aspx code is executed on the server & java script code on the client.
<form id="form1" onSubmit="return valForm1();" runat="server">

Are you having a problem?
you need to add it from the code behindbtnId.Attributes.Add("onclick","newwindow();return false;")EricPascarello.com | Twitter epascarello | LinkedI...function call inside aspx page for function in code behind not executing?
I converted an asp.net .NET 1.1 web application to .NET 2.0 framework.The original .NET 1.1 page runs fine.
The webpage has a datagrid, when a label control tries to be populated by a null value I get the following error:Conversion from type 'DBNull' to type 'Date' is not valid.
Add this code where you want to invoke the function
vbTab & " myJSFuncOnaspxPage(); " & vbCrLf & "</script>")
thanks in advance
in code behind...add this...
protected void Page_Load(object sender, EventArgs e)
if ((this.Request.Params["__EVENTARGUMENT" ] == "DataGrid_OnBlur(Sender, e)"))
where DataGrid_OnBlur is the name of the server side function
I have as server button on the page and onclick i am calling a server function (check())
Some code here
Can any one help me please
Any help would be awsome
You can't call client methods from server code, only the other way around. Unless your insert is a very long operation, the best idea is just to do the insert as normal. i.e. perform the insert on postback, then allow the page markup to render as normal.My Blog
