Gridview Can't Be Seen When Page Is Opened

Feb 7, 2011

I have a page with a gridview on it. The gridview can not be seen when the page is opened. There is a dropdownlist and a button on the page. The user is supposed to make a selection in the dropdown and then click the button (labeled "Go") and then the gridview appears. The problem is that the gridview appears in response to the dropdown selection, before the go button is clicked. I'm sure this is easy but how can I stop the gridview from appearing in response to a dropdown selection? The dropdown is called ddlfilter. This is the code I am using:

Part 1 (continued in next post):
Code:
<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"[URL]>
<script runat="server">
Private Function GetColumnIndexByName(row As GridViewRow, SearchColumnName As String) As Integer
Dim columnIndex As Integer = 0
For Each cell As DataControlFieldCell In row.Cells
If TypeOf cell.ContainingField Is BoundField Then
If DirectCast(cell.ContainingField, BoundField).DataField.Equals(SearchColumnName) Then
Exit For
End If
End If
columnIndex += 1
Next
Return columnIndex
End Function
Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
If Page.IsPostBack() Then
If ddlFilter.SelectedItem.Text.ToString() <> "- ALL -" Then
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Cells(GetColumnIndexByName(e.Row, ddlFilter.SelectedItem.Text.ToString())).CssClass = "viscol"
End If............

C# - COM Port Can't Be Opened In Asp

May 10, 2010

I following this article for sending SMS it is a winform application.. I have referenced all the Dll's to my asp.net application. I use an aspx page to detect a mobile device connected to a PC..... But it alwys shows COM 'n' Port could not be opened.

using SMS;
using GsmComm.GsmCommunication;
using GsmComm.PduConverter;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
GsmCommMain comm = new GsmCommMain(6, 9600, 300);
comm.Open();
if (!comm.IsConnected())
{
Response.Write("No Phone Connected");
}
else
{
SmsSubmitPdu pdu = new SmsSubmitPdu("test", "+919999999999", "");
CommSetting.comm.SendMessage(pdu);
}
}
}

EDIT:

I use the web development server that ships with Visual Studio... If go to Control Panel -> Phones & Modems -> Modems i could see my mobile connected in com6.. i have tested the winform application it works fine.Is this the answer? ASP.NET pages are supposed to work.What is happening over here is that when you click on open_com button, the ASP.NET page posts back to itself, executes the event handler i.e., opensthe port. Then when the page finishesprocessing the post back, it is unloaded. At this point the COM1 objects is also destroyed.

Auto Call Site When Email Opened

Feb 22, 2012

How is it possible to "auto call" a website when an email is opened?

For example, some mail marketing campaign sites offer services to track email clicks and when an email gets opened.

I don't know exactly how they manage to find out when an email gets opened irrespective if they clicked on an link within the email to track clicks.

How does one do this, so when an email gets opened, a silent call is made to a page in the background to indicate that the email has been opened?

C# - StreamWriter Stops Writing When File Is Opened From Web Link?

Mar 22, 2010

Following on from my previous question...

The following code creates log files on a web server:

private void LogMessage(Message msg)
{
using (StreamWriter sw = File.AppendText(_logDirectory + DateTime.Now.ToString("yyyyMMddHH") + ".txt"))
{
sw.WriteLine(msg.ToString());
}
}

The log files are linked to from an admin page on the web site:

foreach (FileInfo file in logDir.GetFiles())
{
Response.Write("<a href='http:// .... /Logs/" + file.Name + "'>" + file.Name + "</a>");
}

I'm getting the problem that after someone looks at one of the log files from the link, that log file stops being written to.

AJAX :: Filtering Data While A Popup Window Is Opened?

Mar 26, 2010

I have a parameter page in asp.net consisting of many parameters. I am using ajax and filtering the values of the parameters based on the hierarchy. For example, only those branchs appear of a department if a single department is selectd on the listbox.

I also have a link button on my parameter screen which opens a popup window with a listbox in it. On the popup window, i select some listitems which i pass through the session into parent page when the popup window is closed. Till now, my popup window gets all the values from the data source to fill the listbox.

What i want now is to show only the filtered values on the popup window based on the selections made on the parent pages' parameters.
