ISP or IP?

The only way you can hope to do that, is if you have a database of IP address ranges which tells you which IPs are assigned for a given ISP. Don't expect to get this for free.

Well, to treat partiular data case by case, you can not use databind method.
Instead, you should use a loop and add the items. Check the data and if it matches your condition(as you say 0 here), make the that a Hyperlink Column. Rose | [Rose]

Alternatively you can look into here

http://www.netrostar.com/Tutorials-91-ASP.NET%20Tutorial.%20How%20to%20use%20Repeater[^]

Niladri Biswas

There are may ways of doing the same.
I am presenting one way of doing it

I am taking a datatable as my datasource(and ofcourse you have also taken that Smile | :)

)

So here it goes

Step 1: Create datatable

DataTable dtSource = new DataTable();

        #region Data Table Creation

        dtSource.Columns.Add("Jurdiction");
        dtSource.Columns.Add("2007");
        dtSource.Columns.Add("2008");
        dtSource.Columns.Add("2009");        

        #endregion

        #region Add Rows
        dtSource.Rows.Add("NC", "0", "6", "3");
        dtSource.Rows.Add("VA", "4", "0", "5");
        dtSource.Rows.Add("NY", "0", "7", "0");
        
        #endregion

Step 2:Create a repeater control in your .aspx page

<asp:Repeater ID="myRepeater" runat="server">
    </asp:Repeater>

Step 3:Bind the datatable to the repeater control which is there in the .aspx page

myRepeater.DataSource = dtSource;
        myRepeater.DataBind();

Step 4:Create a user control say Headercontrol.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="HeaderControl.ascx.cs" Inherits="HeaderControl" %>
<table width="40%">
    <tr>
        <td style="width:10%">
            <asp:Label ID="lblHeaderCol1" runat="server" Text="Jurdiction"></asp:Label>
        </td>
        <td style="width:10%">
            <asp:Label ID="lblHeaderCol2" runat="server" Text="2007"></asp:Label>
        </td>
        <td style="width:10%">
            <asp:Label ID="lblHeaderCol3" runat="server" Text="2008"></asp:Label>
        </td>        
        <td style="width:10%">
            <asp:Label ID="lblHeaderCol4" runat="server" Text="2009"></asp:Label>
        </td>
    </tr>
    </table>

Step 5:Create another user control say ContentControl.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ContentControl.ascx.cs" Inherits="ContentControl" %>

<table width="40%">
    <tr>
        <td style="width:10%">
            <asp:Label ID="lblContentColumn1" runat="server"></asp:Label>
        </td>
        <td style="width:10%">
           <asp:LinkButton ID="lnkContentColumn2" runat="server"></asp:LinkButton>
        </td>
        <td style="width:10%">
            <asp:LinkButton ID="lnkContentColumn3" runat="server"></asp:LinkButton>
        </td>
        <td style="width:10%">
            <asp:LinkButton ID="lnkContentColumn4" runat="server"></asp:LinkButton>
        </td>
    </tr>
</table>

Step 6:Expose the following properties in the ContentControl.ascx.cs

#region Properties

    public string Jurdiction { get; set; }

    public string Content2007 { get; set; }

    public string Content2008 { get; set; }

    public string Content2009 { get; set; }

    #endregion

Step 7: In the Page_Load event of ContentControl.ascx.cs, add the following

protected void Page_Load(object sender, EventArgs e)
    {
        lblContentColumn1.Text = Jurdiction;

        lnkContentColumn2.Text = Content2007;

        lnkContentColumn3.Text = Content2008;

        lnkContentColumn4.Text = Content2009;       
    }

Step 8: Call the Header.ascx user control from inside the <HeaderTemplate> of the repeater and the ContentControl.ascx from inside the <ItemTemplate> of the repeater.

It is given below

<asp:Repeater ID="myRepeater" runat="server">
        <HeaderTemplate>
       <uc2:HeaderControl ID="HeaderControl1" runat="server" />
        </HeaderTemplate>
        <ItemTemplate>
            <uc1:WebUserControl ID="WebUserControl1" runat="server" Jurdiction=<%# DataBinder.Eval(Container.DataItem, "Jurdiction")%> Content2007=<%# DataBinder.Eval(Container.DataItem, "2007")%> Content2008=<%# DataBinder.Eval(Container.DataItem, "2008")%> Content2009=<%# DataBinder.Eval(Container.DataItem, "2009")%> Counter = <%# Container.ItemIndex%> />
         </ItemTemplate> 
        </asp:Repeater>

N.B.~ The various properties that I have exposed from the ContentControl.ascx, are consumed inside the itemtemplate.

So What I am doing?

Basically in the header user control , I have defined the Column names to be printed

and in the ContentUserControl I have attached the cell values to the link buttons.

I am calling the user control from inside the item template ; so each time the user control will be iterated.

N.B.~ This is one of the solutions that came in my mind instantly.

Hope it will help you.

It does not depend on IE 6 or 7, but the security configuration of the browser.

hi
I am using visual studio 2005 C#.

In my web application,
I have one web form which is having on link button

I want that when user click on this link, msn messenger must open it is intalled on PC or it should display msg like "Please intalled msn Messenger"

Regards,

Why do you think that this is possible ? You can link to a local file, but you don't have access to the file system. I think you need to read up on what ASP.NET is and how it works.

If you take a look on the MS / Live site, there's a Messenger control available for embedding into web apps...the same as they usefor Webmessenger

In my web application, I need to display binary image from database in image web control.
I can convert binary data to image, but how to bind it to Image web control?

Please help me.

Hi andiyuniar
I've had this issue before. The way I handled it was to "spoof" a content page to change it's ContentType to display images. I would pass it an id via query string and then set the imageurl to the spoofed page.

Here's an example that should help you. Please keep in mind, I don't know if it's the best solution, but it works for me. Also, there could be some performance hits if you have too many images being loaded on your page via this method.

Create a WebForm... i called mine LoadImage.aspx
Place this code in the Load event

if (Request.QueryString["Id"] != null)
        {
            int Id = Convert.ToInt32(Request.QueryString["Id"].ToString());
            byte[] image = null;
            //You will have to add your connection information and grab the image from the database
            // ToDo: Load binary image into image variable;

                if (image!=null)
                {
                    MemoryStream ms = new MemoryStream(image);
                    Bitmap b = new Bitmap(Image.FromStream(ms));

                    Response.ContentType = "image/jpeg";
                    b.Save(Response.OutputStream, ImageFormat.Jpeg);
                }
                else
                {
                    Bitmap b = new Bitmap(Image.FromFile(Server.MapPath("images/noimage.png")));

                    Response.ContentType = "image/jpeg";
                    b.Save(Response.OutputStream, ImageFormat.Jpeg);
                }
        }
        else
        {
            Bitmap b = new Bitmap(Image.FromFile(Server.MapPath("images/noimage.png")));

            Response.ContentType = "image/jpeg";
            b.Save(Response.OutputStream, ImageFormat.Jpeg);
        }

Then on the page you want to bind your image to just set the ImageUrl property to the webform plus query string.

Image1.ImageUrl = "LoadImage.aspx?Id=1";

Happy Coding

Thanks. it help me.

I am using jquery in my asp.net 1.1 application.
I am reterving some data using this function:

$(function() {
$("input#btnadd").click(function() {
$.get("RecordPage.aspx",function(response) {
// working on response received.
});
alert('Done');
});

Now my problem is alert('Done'); executed first before response part.

One person's data is another person's program.

--J.Walia

I would assume that this means it makes the request, then continues. You need to figure out if you can catch an even when the get has ended, and show your message there.

One way to do this, is to put something in the URL that tells it to inject the alert in the page that is being sent.

   a.LoadAlarmFromDB(ref dt);<br />
   gridviewAlarm.DataSource = dt;<br />
   gridviewAlarm.DataBind();<br />
<br />
   AlertTimer = new Timer();<br />
   AlertTimer.Start();<br />
   AlertTimer.Elapsed += new ElapsedEventHandler(AlertTimer_Elapsed);<br />
   AlertTimer.Interval = 30000;<br />
<br />
}<br />
    public static void AlertTimer_Elapsed(object source, ElapsedEventArgs e)<br />

        gridviewAlarm.DataSource = "";<br />
        gridviewAlarm.DataBind();<br />
        gridviewAlarm.DataSource = m_AlarmDT;<br />
        gridviewAlarm.DataBind();<br />
    }<br />

how do i call non static function in static function?
thanks so much for the help

Regards,

Arif

I think you can not able to call a non-static method from a static method,may be you can change your static function to normal function or you can change the normal function into a delegate function.

You are kind of right, and yet, utterly wrong.
