How to insert or add URL links inside the gridview?

There are many ways to insert or add links inside a grid. There are many ways to display all the pages in your site in a gridview.

This is one way,

<asp:HyperLinkField DataTextField="Modules" HeaderText="Name" NavigateUrl='<% Bind("URL") %>' />

This the second way to do this,

                                                                    <asp:TemplateField HeaderText="Name" SortExpression="Modules">

                                                                        <ItemTemplate>

                                                                            <asp:HyperLink ID="hlModules" runat="server" Text='<%# Bind("Modules") %>' />

                                                                        </ItemTemplate>

                                                                    </asp:TemplateField>

Then add this code in gridview RowCreated event,

if (e.Row.RowType == DataControlRowType.DataRow)

{

    HyperLink hl = (HyperLink)e.Row.FindControl("hlModules");

    hl.NavigateUrl = "MyPage.aspx";

}

But if you want to open the page in a new window or pop up. You need to put this code in RowDataBound event of the gridview and do like this,

           

if (e.Row.RowType == DataControlRowType.DataRow)

{

HyperLink hl = (HyperLink)e.Row.FindControl("hlModules");

      switch(hl.Text)

      {

            case "FirstPage":

                  hl.NavigateUrl = "javascript:OpenFirstPage();";

            break;                       

            case "SecondPage":

                  hl.NavigateUrl = "javascript:OpenSecondPage();";

            break;                       

 …

      }

}

Of course you need to create the javascript to open a pop up window like this,

<script type="text/javascript" language="javascript">

var winArray = new Array()

function OpenFirstPage()

{

if (!winArray[0] || winArray[0].closed)

      winArray[0] = window.open("FirstPage.aspx", "FirstPage", "width=800,height=600,toolbar=no, menubar=no, directories=no, resizable=yes, scrollbars=yes");

else

            winArray[0].focus();

}

function OpenSecondPage()

{

if (!winArray[0] || winArray[0].closed)

      winArray[0] = window.open("SecondPage.aspx", "SecondPage", "width=800,height=600,toolbar=no, menubar=no, directories=no, resizable=yes, scrollbars=yes");

else

            winArray[0].focus();

}

…

</script>

How to close all windows upon signout?

This solution might not be the exact solution to close all open windows, but it does close all windows upon clicking sign out.

First, you need to create a sign out button on your master page. Then put this code your click event of the button.

Here is the code:

            Session.Clear();

            Response.Redirect("~/LoginPage.aspx");

Second, You need to create a login page. I do not need to put the code for the login page. You can do that.

Third, You need to create javascript that will open each page.

Here is the javascript:

    <script type="text/javascript" language="javascript">

        var winArray = new Array()

        function OpenFirstPage() {

            if (!winArray[0] || winArray[0].closed)

                winArray[0] = window.open("FirstPage.aspx", "FirstPage", "width=800,height=600,toolbar=no, menubar=no, directories=no, resizable=yes, scrollbars=yes");

            else

                winArray[0].focus();

        }

        function OpenSecondPage() {

            if (!winArray[1] || winArray[1].closed)

                winArray[1] = window.open("SecondPage.aspx", "SecondPage", "width=800,height=600,toolbar=no, menubar=no, directories=no, resizable=yes, scrollbars=yes");

            else

                winArray[1].focus();

        }

        function OpenThirdPage() {

            if (!winArray[2] || winArray[2].closed)

                winArray[2] = window.open("ThirdPage.aspx", "ThirdPage", "width=800,height=600,toolbar=no, menubar=no, directories=no, resizable=yes, scrollbars=yes");

            else

                winArray[2].focus();

        }

        function SignOut()

        {

            if (winArray[0] == null)

                OpenFirstPage();

            winArray[0].close();

            if (winArray[1] == null)

                OpenSecondPage();

            winArray[1].close();

            if (winArray[2] == null)

                OpenThirdPage();

            winArray[2].close();

        }

    </script>

Fourth, You need to add attributes to your sign out and button.

Here is the code:

this.lnkUser.Attributes.Add("onclick", "javascript:OpenFirstPage()");

this.lnkTeams.Attributes.Add("onclick", "javascript: OpenSecondPage()");

this.lnkVolunteers.Attributes.Add("onclick", "javascript: OpenThirdPage()");

this.lnkLogout.Attributes.Add("onclick", "javascript:SignOut()");

How to do multiple popup window using ASP.NET 3.5 and AJAX Control and Javascript?

    

There are three ways to popup a new window. The first way to do popup window,

this.lnkNewWindow.Attributes.Add("onclick", "window.open('NewWindow.aspx', 'NewWindow', 'toolbar=no, menubar=no, directories=no, resizable=yes, scrollbar=yes');return false;");

this the second way to do popup window,

<asp:LinkButton ID="lnkNewWindow" runat="server" Text="New Window" onclick="javascript:openNewWindow();” />

Put this javascript inside script tag,

  function OpenNewWindow()

  {

  window.open('NewWindow.aspx', 'NewWindow', 'toolbar=no, menubar=no, directories=no, resizable=yes, scrollbar=yes');

return false;

  }

This is the third way to do popup window,

this.lnkNewWindow.Attributes.Add("onclick", "javascript:OpenNewWindow();");

To close this window just call window.close() like this,

this.btnClose.Attributes.Add("onclick", "window.close()");

If you are doing popup window that has functionality of exporting to pdf or excel with multiview control and updatepanel. You need to put postback trigger. Here is my link.

How to extract data from site?

Web scraping (also called Web harvesting or Web data extraction) is a computer software technique of extracting information from websites.

Here is the code that extract the content of a specific site,

WebClient wc = new WebClient();

string html = string.Empty;

MatchCollection matches;

string url = string.Empty;

int id = 0;

html = wc.DownloadString(urlPath).Replace("<html>", "").Replace("</html>", "").Replace("<!DOCTYPEHTML>", "").Replace("<head>", "").Replace("</head>", "").Replace("<script>", "").Replace("</script>", "");

matches = Regex.Matches(html, "<a.*?href=\"(.*?)\".*?>(.*?)</a>", RegexOptions.IgnoreCase | RegexOptions.Singleline);

if (destinationList == null)

      destinationList = new List<clsDestinations>();

foreach (Match match in matches)

{

      string matchUrl = match.Groups[1].Value;

      //For internal links, build the url mapped to the base address

      if (match.Groups[0].Value.Contains("travel/landing_page_hotels.cfm"))

      {

            url = MapUrl(urlPath, match.Groups[1].Value);

            if (url.Length > 0)

            {

                 destination = new clsDestinations();

                 id += 1;

                 destination.ID = id;

                 destination.Url = url;

                 destination.CityName = match.Groups[2].Value;

                 if (!destinationList.Exists(d => d.CityName == destination.CityName))

                       destinationList.Add(destination);

             }

      }

}

                foreach(clsDestinations cy in destinationList)

                {

                    if (!cityBll.CheckForDuplicateCity(cy, false))

                        result += cityBll.InsertCity(cy); 

                }

How to upload and download files thru FTP Server?

I have use several references in creating this window application. I have somehow simplified it and extract codes from the references that I have used.
