In a C# 2010 web form application, I would like to know how to setup server side validators to check the format of a date in mm/dd/yyy format. Basically this would be like a regular expression, custom validator, compare validator. I basically need to validate the mm/dd/yyyy format includes for month, date, year. I also am required to make certain the user enters the date with the '/'. enter.
Can you tell me how to accomplish this goal?

Following regex can be used for it for format MM/dd/yyyy:
^(0[1-9]|1[012])[/](0[1-9]|[12][0-9]|3[01])[/](19|20)\d\d$
On server side, you can use Regex.Match to check the string and validate it.
Refer: C# Regex.Match[^]
I would prefer Masked Textbox for input itself: Enhanced Textbox Control[^]

I use the calendar, it easier on me and the user.

I have sign in panel and sign up panel in the same default.aspx page.
i have kept a validation setting with required rule in all textbox in both panels.
now the problem, when user try to sign up and click submit button it will ask him to enter data in the sign in textbox, i guess because all are in one but asp.net won't allow multipe forms in the same page.
what can i do?

I think, you have to set ValidationGroup for Signin and Signup to check for respective submit.

Although i have never used URL rewriting but it seems like your Config file have incorrect elements.
your last section
<rewriter>
<rewrite url="/tags/(.+)" to="/tagcloud.aspx?tag=$1" />
</rewriter>
should be like,
<RewriterConfig>
<Rules>
<RewriterRule>
<LookFor>pattern to look for</LookFor>
<SendTo>string to replace pattern with</SendTo>
</RewriterRule>
<RewriterRule>
<LookFor>pattern to look for</LookFor>
<SendTo>string to replace pattern with</SendTo>
</RewriterRule>
...
</Rules>
</RewriterConfig>
Please Refer MSDN Article[^]
Hope above like will resolve your issue.

Hi,

Hi There.
I am having a problem in populating html table from database dynamically. What i mean is that i
have a table in database that have let say 10 enteries, I want to display those 10 entries in a
html table using loop. I am new to ASP.NET, I've previously woked in php. I can present the
scenario in php and please help me do the same thing in ASP.NET. In php what i normally do is
search the database, grab the table in fetch array and in html table i create one row and use
while loop so that all of the 10 entries are populated at runtime. Here is a demonstration
code in head:
<pre lang="PHP">= mysql_query(
in body code:
<table>
<tr>
<td>Username</td>
<td>Email</td>
<td>Position</td>
<td>Status</td>
</td>
//start of the loop
<?php while($fetch = mysql_fetch_array($query) { ?>
<tr>
<td><?php echo $fetch["username"]; ?> </td>
<td><?php echo $fetch["email"]; ?> </td>
<td><?php echo $fetch["position"]; ?> </td>
<td><?php echo $fetch["status"]; ?> </td>
</tr><?php } ?>//End of loop
</table>
When i use foreach loop in asp.net to do the same thing the it displays only the last row in the
database table...I am using three tier architecture...
projectsLoad_BLL bo = new projectsLoad_BLL();
DataSet ds = new DataSet();
DataTable dt = ds.Tables[0];
int num = 1;
foreach (DataRow dr in dt.Rows)
{
lblno.Text = num.ToString();
lblusername.Text = dr["username"].ToString();
lblemail.Text = dr["email"].ToString();
lblposition.Text = dr["position"].ToString();
lblstatus.Text = dr["status"].ToString();
dt.NewRow();
num++;
}
In HTML Table:
<table>
<thead>
<tr>
<th>No.</th>
<th>Username</th>
<th>Email</th>
<th>Position</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<tr>
<td><asp:Label ID="lblno" runat="server"
Text="Label"></asp:Label> </td>
<td><asp:Label ID="lblusername" runat="server"
Text="Label"></asp:Label></td>
<td><asp:Label ID="lblemail" runat="server"
Text="Label"></asp:Label></td>
<td><asp:Label ID="lblposition" runat="server"
Text="Label"></asp:Label></td>
<td><asp:Label ID="lblstatus" runat="server"
Text="Label"></asp:Label></td>
</tr>
</tbody>
</table>
I know that this method is wrong...if anyone can point to the right direction...thanks in
advance

You can use ASP.NET Repeater control for the purpose. It will be sufficient for your need. For more details on Repeater Control check out here[^]. It also has a sample code at the end. Try it and post if you face any problem. I will be happy to help you.

Thank You very much for your help. I've managed to use asp repeater with datatables efficiently. What i did is added a repeater in asp markup and bind it to dataset. And in i've placed <%# Eval("columnName") %> and viola. All operations are working fine. Thanks again!
|
|
|
|
|
Using Repeater is certainly a very good choice. I am happy that it worked for you  I have one more suggestion - if you are having only read-only records i.e. you only view them, then consider using SqlDataReader object instead of the DataSet as it is fast - read-only - forward only.
Happy to help you
Always Keep Smiling.

You should create a container, it can be a table called table_Container, and then loop threw the dataset, and create your tableRow and cells in code.
You can use the repeater control, but I think you should learn the basics first. Do not use Response.write(""), because response write is reserved for higher level responses like a page error code, or a data set or something.
PHP doesn't have html objects, so echo("tr" is quite common, but is poor practice in general.
foreach (DataRow dr in dt.Rows) {
TableRow tr = new TableRow;
table_Container.controls.add(tr);
TableCell td = new TableCell;
tr.controls.add(td);
Label lbl_UserName = new Label;
lbl_UserName.text = dr["username"];
td.controls.add(lbl_UserName);
}

I totally agree with him that you should learn basic thing how to create response.write(".

Did you not click on the link. It is what you asked for. If that doesn't help then try using Google to search for what you want or, better, go read the documentation until you understand how to do it.

What is ref and out and how to use in asp.net ?
Please explain with an example .
|
|
|
|
|
See the documentation[^].
One of these days I'm going to think of a really clever signature.
|
|
|
|
|
|
ref is used in vb.net and out is used in c#
like this
private sub add(byref a as int,byref b as int)
a=45
b=56
End Sub
example it is on
button click sub
add(a,s)
End Sub

but the email was not sent to any
"gmail or yahoo mail address."
when i tried to sent an email to gmail or yahoo account the following error occurs,
"Bad sequence of commands. The server response was: This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server."
here is my code :
protected void SendEmail()
{
SmtpClient smtpClient = new SmtpClient("mail.mydomain.com", 25);
MailMessage Msg = new MailMessage();
//------for Email Data----------------------------------
Msg.To.Add(TxtEmail .Text .Trim ());
Msg.From = new MailAddress("tehnical@mydomain.com");
Msg.IsBodyHtml = true;
//----Get Max userid------------------------------
