Hey.
I am using ASP.NET to develop a website, so far it has been fine - postback calls btnSubmit_ServerClick.
However I now wish to have some drop down lists (for dates) where the amount of days available changes according to the month selected. But when this posts the page back how do i make sure btnSubmit_ServerClick is not called aswell as drpMonth_OnChange.
I have a nasty feeling i am being an idiot but have become confused.
Thanks for reading this.
Cheers
Dan

Does the drop down automatically post back, or do you have to click the button in order to postback when the drop down changes?
If you have to click the button then you are naturally going to get the button click event being handled.

hmmm i think something may be going wrong, I have checked my event handlers and the wireup code, also I have fixed ASP.NET a few times (due to events not being fired when they should) but the dropdownlist doesn't appear to autopostback.
Edit* Hadn't set autopostback - thought I had sorry to waste your time, thanks very much any way thought *
Cheers

Depending on the type of application, you may not want to refresh a users page when another person opens that application. Just imagine if someone is entering data, and is about finished, when your application refreshes their page, losing all their info.

|

tnx for answer, but on that step of developing me need some tool/technology for synchronized refresh/repaint web page for all visitors when one of them coming or leaving w/o timers.
i hope problem is clear?

I have seen lots of postings regarding adding rows to boud gridviews.
I need to add Rows to a NOT bound gridview.
The issue is I need to read the data frmo a sql query, and manipulate the grid based on the data, so a bindging will not work.
I need to know how to do an ADDROW to the gridview.
Thank you.

The easiest way you will find is to use databinding. You can get the data from your query, manipulate it and either create a new datasource to bind the grid to use the exist resultset.
only two letters away from being an asset

Hello
having a problem with this web service. VS [2005]
The message we get when we try and add the web reference is "unable download following files http://10.0.1.7/codered/service.asmx?wsdl". Which is using the internal ip address of the web server. We have check the IIS where the web service has been published to. But could not see why it is using the internal ip and not the external ip address. The actual url is [url]http://83.100.199.125/codered/service.asmx[/url]
Here is the service description sample, maybe someone can check this, as this has the internal ip address at the bottom.
<br />
wsdl:definitions targetNamespace="http://tempuri.org/"<br />
<br />
wsdl:types><br />
<br />
s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/"<br />
<br />
<br />
wsdl:binding<br />
<br />
wsdl:service name="Service"<br />
<br />
wsdl:port name="ServiceSoap" binding="tns:ServiceSoap"<br />
soap:address location="http://10.0.1.7/codered/service.asmx"/<br />
wsdl:port<br />
<br />

soap12:address location="http://10.0.1.7/codered/service.asmx"<br />
wsdl:port<br />
wsdl:service<br />
wsdl:definitions<br />
I am really hopping someone can help me with this problem.
Many thanks if you can,

align currency values to the right in the grid cell
t.aransiola
|
|
|
|

You have to use the ItemStyle property to align the Grid Cells.
If you want to align the text in a control, then you have to add,
CONTROLNAME.Style.Add("text-align","right")
|

thanks for ur patience with me. pls how do i apply this to a grid column. let say column 4?

You can modify the following code to suit your need.
//Ldt_due can be in mm/dd/yyyy or mm/dd/yyyy hh:mm:ss format
var l_dt = new Date();<br />
var today = Date.UTC( l_dt.getFullYear(), l_dt.getMonth()+1, l_dt.getDate(),0,0,0);<br />
<br />
<br />
var Ldt_Year,Ldt_Month,Ldt_Day<br />
Ldt_Year = String(Ldt_due).substring(0,4)<br />
<br />
if ( String(Ldt_due).charAt(6) == "/" ){<br />
Ldt_Month = String(Ldt_due).substring(5,6);<br />
if ( String(Ldt_due).charAt(8) == " " ){<br />
Ldt_Day = String(Ldt_due).substring(7,8);<br />
}<br />
else{<br />
Ldt_Day = String(Ldt_due).substring(7,9);<br />
}<br />
}
else{<br />
Ldt_Month = String(Ldt_due).substring(5,7);<br />
if ( String(Ldt_due).charAt(9) == " " ){<br />
Ldt_Day = String(Ldt_due).substring(8,9);<br />
}<br />
else{<br />
Ldt_Day = String(Ldt_due).substring(8,10);<br />
}<br />
}
<br />
starttime = Date.UTC( Ldt_Year, Ldt_Month , Ldt_Day,0,0,0);<br />
<br />
if ( starttime <= today ){<br />
alert("Date Due cannot be less than or equal to today's date.");<br />
return 1;<br />
}

We used to have a similar problem with the compare validator and two dates.
We were entering dates in British dd/mm/yyyy format but the validators work by default with American mm/dd/yyyy dates. The answer is to include a globalization element in your web.config:
<system.web>
<globalization requestEncoding="utf-8" responseEncoding="utf-8" culture="en-GB" uiCulture="en-GB"/>
</system.web>
Cheers,
Dave.

U r right iam using this script with 'mm/dd/yyyy' format when iam filling the two dates:
onclick="javascript:popUpCalendar(this, TxtFrom, 'mm/dd/yyyy',-10,-200)"
i added the element u gave me but didnt change still giving alert i f i choosed a fromdate in 2006 and todate in 2007.
Any ideas i would be thankful..

I have never used a popup calendar because I think it is quicker for a user who may have just entered a name and address, perhaps, to continue to use their keyboard to enter a date (or two).
Anyway, that should not be relevant to the immediate problem. Try the following...
Create a page with the following content:
<%@ Page Language="VB" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Test</title>
</head>
<body>
<form id="form1" runat="server">
<div>
Date Range:
<asp:Textbox id="txtDate1" runat="server" columns="15" Text="01/04/2006" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="txtDate1" ErrorMessage="Date must be entered" Display="Dynamic" />
to
<asp:Textbox id="txtDate2" runat="server" columns="15" Text="03/01/2009" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ControlToValidate="txtDate2" ErrorMessage="Date must be entered" Display="Dynamic" />
<asp:CompareValidator ID="CompareValidator1" runat="server"
ErrorMessage="Date must be in the format dd/mm/yyyy and it must be after the first date"
ControlToValidate="txtDate2" Type="Date" Display="Dynamic" Operator="GreaterThanEqual"
ControlToCompare="txtDate1" />
</div>
</form>
</body>
</html>
... then test it, change the second date to 03/01/2006 and press the tab key. A suitable error message should appear. Change the second date to 03/01/2007, press the tab key and the error message should disappear.
Hope that helps. If not try looking in C:\Inetpub\wwwroot\aspnet_client\system_web\1_1_4322\WebUIValidation.js (assuming you are running IIS and your website root folder is C:\Inetpub\wwwroot). I'm not sure if this is the up-to-date JavaScript validation code, especially if you are using ASP.NET 2.0 (or 3.0!) but the version number of 125 suggests it is OK.
I really hope my example helps because the JavaScript code takes a fair bit of time to get to understand.
Cheers,
Dave.

Hello all!
Happy new year!
I have a problem with a bizarre ImageButton. It keeps "causing validation". It is part of a table and I use the following code to create it (C#):
ImageButton cmdDelete = new ImageButton();
cmdDelete.CommandName = "Delete";
cmdDelete.CommandArgument = p.DbId.ToString();
cmdDelete.Command += DeleteRecipient;
cmdDelete.ImageUrl = "~/Images/trash.gif";
cmdDelete.CausesValidation = false;
cmdDelete.OnClientClick = "javascript:Page_ValidationActive=false;";
1. Causes validation is false.
2. OnClientClick is set to "Page_ValidationActive=false" - which I've heard should be equal to 1., just for the client.
Now it behaves like this:
The first time it is clicked, it does not cause validation, and the user is deleted and removed from the list. If I click to delete another user, suddenly the button causes validation. If I click it again, it does not! And so on, and so on.
I've tried stepping through the code, and every second time the button is clicked, it causes validation.
Validation occurs server side, since I've tried turning off JavaScript, and the exact same pattern occurs.
I'm kind of confused! LOL!
Best regards
Soeren

I’ve added namespace System.Web.Security in the forms of my application. I use it for Forms Authentication functionality. Because of it, while redirection to another page the information stored in the session is deleted. I’ve also used method of FormsAuthentication class to redirect to another page. Still it is not storing data in the session. Please tell me the solution on this.

Where is your session state being held? If you are using In-proc on a multi-processor machine or against multiple servers then you will find this problem. Change the session state to use the ASP State Server to sort this out. This is an example:
<sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="20"/>
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.
