I usually create a dummy item for the select and then append it to the top of my datasource.
Personally I don't like data binding so would rather populate the list with the associated loop instead making it more obvious what is going on and giving this level of control more naturally.
Either flavor will work in your situation ... one more suggestion is to use Javascript for the entire procedure instead of postbacks or ajax which really works well for small lists.

Hi First time it comming fine because it's clear so now In the SelectedIndex_Changed event
DropDownLost1.Clear();
Code to bind data to DropDownList
Then DropDownList1.Items.InsertAt(0,"Select");
I think it will solve your problem

Hi All,
I'm working in Asp.Net 2.0. I've a text box and search button. If I type text in the text box, data should show the bottom of the text box with starts the name of typed character.
For Ex., I type the country name in the text box. I have the country list in my database. If I type 'I', the bottom of the text box should show India, Indonesia, etc. I tried with Autocomplete ajax tool kit. It is working their demonstration, but not in my appn.
Thanks in adv.

How to create Thai Language PDF file using EasyPDF from Asp.net?

I guess you should read the docs, then ask the people who wrote EasyPDF.

Hiii...
Please help me in this problem.
Problem In ASP.NET WebPage:
In webpage i have GridView. In javascript when i write
document.getElementByID('Gridview1') it shows id. means Gridview found.
But when i put same code in Content Page
it shows null.
var grid = document.getElementById(gridViewId); --> Shows null.
After that When page gets loaded .. i put alert on same code
var grid = document.getElementById(gridViewId); --> It Shows Object Found...
Why this happened ???

What happened is that the id changes because it is in a content section.
Use document.getElementById("<%=gridViewId.ClientID %>"); instead
I didn't get any requirements for the signature

|
|
|
if u r using ur code, var grid = document.getElementById(gridViewId) it always give only the access of gride.
instead of this u can use document.getElementsByTagName('td')
Thanks

Hi CP ,
I am using an iFrame in an application . i am setting focus to it to type the text .
After typing some text i want to press the keys using combination like this ::
" ctrl+shift+p "
like what we do normally in iFrame i.e., Ctrl+X, Ctrl+V ,Ctrl+y ,Ctrl+C .
I am using shortcuts.js JS File for generating normally it is working for textarea/ any control if it is having the focus. from the below site.
http://www.openjs.com/scripts/events/keyboard_shortcuts/#keys
<title>Untitled Page
shortcut.add("ctrl+shift+p", function ()
{
document.getElementById('<%=Button1.ClientID%>').click();
}
,{
//'type':'keydown',
//'propagate':false,
//'target':document.getElementById('ifrm')
//}
);
function LoadFrame()
{
document.getElementById("ifrm").contentWindow.document.designMode = "On"; //Registering the keydown event
// frames[0].document.onkeydown = function () {
// keypressed=frames[0].event.keyCode;
// if(keypressed==80)
// {
// ctrlPressed = true;
// return false;
// }
// if(keypressed==17)
// {
// shiftpressed = true;
// return false;
// }
// if(keypressed==16 && ctrlPressed && shiftpressed)
// {
// short()
// ctrlPressed=false;
// shiftpressed=false;
// return true;
// }
// return true;
// };
// But this not the Exact way .& this is time taking for events to fire atleast 3 times for all buttons to be pressed.
}
<asp:button id="Button1" runat="server" text="Button" xmlns:asp="#unknown">
This is the code which i am using currently . I want to use the keyboard shortcuts, if iframe is having the focus.
I request to give the suggestions/output without leaving the question unanswered.
Regards, Sriram.

Getting all the checkbox object reference use the following script.
var getAllcheckbox = document.getElementsByTagName("INPUT");
for(var i=0;i<getallcheckbox.length;i++)>
{
if(getAllcheckbox[i].type == "checkbox" && getAllcheckbox[i].name = "check[]")
{
//do your validation here...
}
}

Hi,
Iam writting a c# DLL for users login. Here i need to get the machine name of the client who is accessing my class. In case if we are designing a website we can write the following code to get the machine name
string[] aStrComputerName = System.Net.Dns.GetHostEntry(Request.ServerVariables["remote_addr"]).HostName.Split(new Char[] { '.' });
string strMachineName = computer_name[0].ToString();
But I cant use this code in C# class because Request.ServerVariables is not supported in c# class.
Can any body help me to solve this problem.

You can use Windows Management Instrumentation (WMI) to get this information, Try this sample code.
using System;
using System.Management;
using System.Windows.Forms;
namespace MyComputerName
{
public class GetComputerName
{
public static void Main()
{
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_ComputerSystem");
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("Client Computer Name is : {0}", queryObj["Name"]);
}
}
catch (ManagementException e)
{
MessageBox.Show("Oops ! ERROR : " + e.Message);
}
}
}
}

HI,
I have used the following code to find the pc name of the client in server, when a request comes
System.Net.Dns.Resolve(Request.ServerVariables("REMOTE_ADDR")).HostName.Split(".")(0).ToString()
This is working fine and able to get the pc name when the request comes with out through a proxy server.
But when the request comes through same proxy, for different machines I could get only the proxy name only.
Is there any way to get the machine even if it comes through proxy? or at least any way to identify that this the request comes from a proxy so that in server we can restrict.
I would really appreciate any help/guidance for this..
Thanks very much in Advance!
