Here what i have to do is create a new user and send a verification mail to the email id provided by the user. User is being created without any problem, But I am finding bit hard to insert code for sending email id.
A little help is much appreciated. I need some guidance to send verification email to new users.
The System.Net.Mail namespace contains the various classes that are related to email. You can use some of the classes to send email. More information on this here
Also, it is recommended that the server-side processing code be put in the aspx.cs file (code behind) than embedding directly into the ASPX page.

I have this and I want to hide rows dynamically using vb.net codebehind.
I am using VS2010.
This is my table:
<table>
<tr id="FromDateRow">
<td><asp:Label ID="FromDateLabel" runat="server">From date:</asp:Label></td>
<td>
<input type="text" id="txtFromDateF" class="needs-datepicker" />
<asp:TextBox id="txtFromDate" CssClass="hidden" runat="server" />
</td>
</tr>
<tr id="ToDateRow">
<td><asp:Label ID="ToDateLabel" runat="server">To date:</asp:Label></td>
<td>
<input type="text" id="txtToDateF" class="needs-datepicker" />
<asp:TextBox id="txtToDate" CssClass="hidden" runat="server" />
</td>
</tr>
<tr>
<td><asp:Label ID="CustomerCodeLabel" runat="server">Customer Code</asp:Label>:</td>
<td><asp:DropDownList ID="CustomerCodeDropDownList" runat="server" AutoPostBack="False" /></td>
</tr>
<tr>
<td><asp:Label ID="CINumberLabel" runat="server">CI Number</asp:Label>:</td>
<td><asp:TextBox ID="CINumberTextBox" runat="server" /></td>
</tr>
</table>
Now I want to do something like this:
Select Case value
Case DisplayDates.FromDate
ToDateRow.CssClass = "hidden"
FromDateRow.CssClass = ""
Case DisplayDates.ToAndFromDate
ToDateRow.CssClass = ""
FromDateRow.CssClass = ""
Case Else
ToDateRow.CssClass = "hidden"
FromDateRow.CssClass = "hidden"
End Select
For some reason I cannot access the ToDateRow and the FromDateRow from my codebehind.
The objects you are trying to reference in codebehind (the relevant tr elements) needs to be defined as runat="server"
If CssClass is not a known property for the object instance try using the following:
rowObject.Attributes.Add("class", "hidden");
You must have
runat="server
tag in table and tr to access from code behind.
After comment :
ToDateRow.Attributes("class") = "CssClass";
Ok I solved it.
By adding the runat="server" i was able to access the row.
And then I found the "visible"-property.
Now it works just fine.
Thx for the help
I have a master page and based on that master page I created a page with a TextBox and two Validation controls for RequiredValidator and RegularExpressionValidator and one ValidationSummary.
when pressing the enter key in TextBox, I expected that both validator show their errorMessage on validationSummary but thats not what happening it only works when I press the button on page.
According to this page I wrapped my code with <asp:panel> and a DefaultButton attribute but it didn't solve the problem.
http://www.codeproject.com/KB/aspnet/aspnet_Enter_key_problem.aspx
I want to know what the problem here is and whether there is any workaround?
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
**<asp:Panel runat="server" DefaultButton="EmailSend">**
<table style="width: 100%">
<tr>
<asp:ValidationSummary ID="EmailValidation" runat="server" CssClass="failureNotification"
ValidationGroup="EmailValidation" />
</tr>
<tr>
<td style="width: 76px">
Email:
</td>
<td class="style1">
<asp:TextBox ID="EmailForget" runat="server" Width="244px"></asp:TextBox>
</td>
<td>
<asp:RequiredFieldValidator ID="EmailRequiered" runat="server" ControlToValidate="EmailForget"
CssClass="failureNotification" ErrorMessage="RequiredFieldValidator" ValidationGroup="EmailValidation">*</asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="EmailRegular" runat="server" ControlToValidate="EmailForget"
CssClass="failureNotification" ErrorMessage="email required"
ValidationGroup="EmailValidation">*</asp:RegularExpressionValidator>
</td>
</tr>
<tr>
<td style="width: 76px">
</td>
<td class="style1">
<asp:Button ID="EmailSend" runat="server" Text="send" Width="56px" ClientIDMode="Static" />
</td>
<td>
</td>
</tr>
</table>
**<asp:Panel>**
</asp:Content>
Try adding this code
<script type="text/javascript">
if (document.addEventListener) {//if Firefox
document.addEventListener("keypress", fireFoxHandler, true);
} else {
document.attachEvent("onkeyup", ieHandler);
}
function fireFoxHandler(evt) {
if (evt.keyCode == 13) {
document.getElementById("EmailSend").click();
}
}
function ieHandler(evt) {
if (evt.keyCode == 13) {
document.getElementById("EmailSend").click();
}
}
</script>
Found this solution here.
(I didn't check this in MasterPage scenario, please check...)
If you are using IE then according to the answers on these two pages:
ASP.NET enter key and form submit with no javascript
Enter button does not submit form (IE ONLY) ASP.NET
you only need to add the following to your form
<!-- Fix for IE bug submit on pressing "Enter") -->
<div style="display:none">
<input type="text" name="hiddenText"/>
</div>
I solved this problem like this:
protected void Page_Load(object sender, EventArgs e)
{
textboxusername.Attributes.Add("onKeyPress", "javascript:if (event.keyCode == 13) __doPostBack('" + LinkButton1.UniqueID + "','')");
textboxpassword.Attributes.Add("onKeyPress", "javascript:if (event.keyCode == 13) __doPostBack('" + LinkButton1.UniqueID + "','')");
}
and this is the link..
<asp:LinkButton ID="LinkButton1" runat="server" class="btn" OnClick="LinkButton1_Click">
in my asp.net website i can only login in Firefox but not in chrome, internet explorer or safari.
here is my code :
string userName = LoginUserName.Text;
string password = LoginPassword.Text;
if (Page.IsValid)
{
if (Membership.ValidateUser(userName, password))
{
if (RemeberMe.Checked == true)
{
Response.Redirect("~/Home.aspx");
}
}
}
here is the login table :
<table>
<tr>
<td>
<asp:Label Text="Email:" AssociatedControlID="LoginUserName" runat="server"
id="LoginUserNamelabel" CssClass="label"></asp:Label>
</td>
</tr>
<tr>
<td>
<asp:TextBox ID="LoginUserName" runat="server" Width="250px" CssClass="textbox"/>
<asp:RequiredFieldValidator id="LoginEmailRequired" runat="server" ControlToValidate="LoginUserName"
ErrorMessage="Email is required" ToolTip="Email is required"></asp:RequiredFieldValidator>

using the AspNetSqlMembershipProvider.
i am using asp.net 4.0 , what is the problem
thanks
You always validate the username and password, but then only actually redirect if the user has checked the "Remember me" - This looks wrong. Could there be a co-incidence that you ticked the box in some test sessions but not others? ;)
Also you're not actually storing the fact that the user has logged in anywhere, so won't you have problems later with the User.Identity.IsAuthenticated still being false?
You should be using something like
FormsAuthentication.RedirectFromLoginPage Method whether or not the checkbox is checked...
If you want to do the redirect yourself you should be using FormsAuthentication.SetAuthCookie and then doing the redirect.
EDIT: Something like this
string userName = LoginUserName.Text;
string password = LoginPassword.Text;
if (Page.IsValid)
{
if (Membership.ValidateUser(userName, password))
{
if (RemeberMe.Checked)
{
// Set your own cookie here or something that you will later check for in Page_Load etc
}
// Need to tell ASP.NET authentication was successful
System.Web.Security.FormsAuthentication.SetAuthCookie(userName, True)
Response.Redirect("~/Home.aspx");
}
}
If you are hitting http://localhost then most of the browsers won't save the cookie that's being generated by your membership provider.
If this is the case, access it by a name that has a dot in it. See:
Cookies on localhost with explicit domain
Are cookies enabled in all these browsers? The most common culprit to the out-of-the-box ASP.NET login stuff "not working" is because by default, they have no fallback for when cookies are disabled.
I am using validation summary control to display error messages of asp.net validation controls.
There are some validations in page for which validation controls are not being used. I am using custom javascript and jquery code for these. Kindly guide how I can display messages of these errors in validation summary control along with asp.net validation controls.
The key is to use the Custom Validation control. This control supports client side scripting (so you can still use your javascript code to do it) but still ties into the validation framework asp.net provides.
From the microsoft article, something like this:
<SCRIPT LANGUAGE="JavaScript">
function validateLength(oSrc, args){
args.IsValid = (args.Value.length >= 8);
}
</SCRIPT>
<asp:Textbox id="text1" runat="server" text="">
</asp:Textbox>
<asp:CustomValidator id="CustomValidator1" runat=server
ControlToValidate = "text1"
ErrorMessage = "You must enter at least 8 characters!"
ClientValidationFunction="validateLength" >
</asp:CustomValidator>
As Patrick said you can add the custom validator controls in place of your custom javascript/jQuery code. And then accordingly you can add the summary validation control. Also you can change the error message in your javascript code. Please check the below code for your reference.
<script type="text/javascript">
function validatetxtLength(source, args)
{
var txtVal=document.getElementById('<%=txtusername.ClientID %>').value;
if(txtVal=="")
{
document.getElementById('<%=custxtValidator.ClientID %>').setAttribute("errormessage","Please Enter the User Name");
args.IsValid=false;
}
else if(txtVal.length>9)
{
document.getElementById('<%=custxtValidator.ClientID %>').setAttribute("errormessage","Username must have less than 10 characters");
args.IsValid=false;
}
else
{
args.IsValid=true;
}
return;
}
</script>
