scrollbar
Thanks for the reply about the printer. Another question if you don't mind: I have a repeater on my form that appears if there is an error in one of the textboxes after the user clicked the save button. After the user clicked the button and if the repeater appears how can i set the scrollbar to be positioned where the repeater is? Thanks
multiple buttons
Hi, I am not sure if this is the right forum but i will try asking anyway. I have an aspx page with multiple buttons. I want to avoid postback so i want to use js. When i click on the buttons each takes me to the same page just with a different aprst: practice.aspx?aprst= I tried the following but nothing happens when i click the buttons: aspx: <script language="javascript"> function SbtForm (aspr) { if (aspr == "ads") { document.Form1.submit ="practice.aspx?aprst=1"; } if (aspr=="new") { document.Form1.submit ="practice.aspx?aprst=0"; } } </script> </HEAD> <body> <form id="Form1" method="post" runat="server"> <TABLE id="Table1" cellSpacing="1" cellPadding="1" width="300" border="1" align="center"> <TR> <TD> <asp:Button id="btnAllAds" runat="server" Text="מודעות " Width="92px"></asp:Button></TD> <TD> <asp:Button id="btnNewAds" runat="server" Text="מודעות חדשות" Width="121px"></asp:Button></TD> </TR> vb.aspx: Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Put user code to initialize the page here btnAllAds.Attributes.Add("onClick", "SbtForm ('ads');") btnNewAds.Attributes.Add("OnClick", "SbtForm ('new');") End Sub
now i get an error message
I have modified the js to: function SbtForm (aspr) { if (aspr == "ads") { document.Form1.action = "practice.aspx?aprst=1"; } if (aspr=="new") { document.Form1.action="practice.aspx?aprst=0"; } document.Form1.submit() } </script> It now takes me to another page but with the following error: The viewstate is invalid for this page and might be corrupted. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I think i know why he is giving you this error. when you are redirecting, ASP.NET thinks it was a postback, and tries to load the viewstate, but since no viewstate data was sent to the server, he shoots out an error. what i suggest doing, is instead of using the QueryString, consider using a hidden form variable: <input type="hidden" name="aprst" value="" id="myHidden" /> ... and the jscript function: document.getElementById("myHidden").value = "whatever"; document.myForm.submit(); //Add this line, or nothing will happen! After the form was submitted (ie, we simulated a postback), use Request.Form["aprst"] to get the value. Hope this works
pleeze help
Hi, I don't understand exactly how to submit the form to another page. This is what i did so far: ASPX: function sbtBtns (aspr) { if (aspr == "cancel") { document.getElementById("myHidden").value = "cancel"; } if (aspr=="new") { document.getElementById("myHidden").value = "new"; } document.Form1.submit(); } </script> <form id="Form1" method="post" runat="server" > <asp:Button id="Button1" runat="server" Text="new"></asp:Button> <asp:Button id="Button2" runat="server" Text="cancel"></asp:Button> <input type=hidden id=myHidden name=myHidden value=""> </form> aspx.vb: Button1.Attributes.Add("onclick", "sbtBtns('new');") Button2.Attributes.Add("onclick", "sbtBtns('cancel');")
