0 – 5

5 – 10

10 – 15

15 – 20

25+

If you had selected multiple like 5 – 10 & 10 – 15 then Values be like 5 – 15.

So, Here is the code for that,

protected void btn1_Click(object sender, EventArgs e)
{
String values = “”;
for (int i = 0; i < cbl1.Items.Count; i++)
{
if (cbl1.Items[i].Selected)
{
values += cbl1.Items[i].Value + “,”;
}
}
values = values.TrimEnd(‘,’);
lbl1.Text = Combine(values);
}

//Function which actually returns the combine values

public string Combine(string input)
{
//First remove all the white spaces
string result = input.Replace(” “, string.Empty);
//Split on each ,
string[] results = result.Split(‘,’);
//Now split on each -
List<string> final = new List<string>();
//Split on each dash
foreach (string s in results)
final.AddRange(s.Split(‘-’));
//Remove duplicates
final = final.Distinct().ToList();
//Return the first and the last element
return string.Format(“{0} – {1}”, final.First(), final.Last());
}

First Create the database in Sql.

After that create web service in asp.net with c#.

the code is like below.

public class LoginDetails : System.Web.Services.WebService
{
SqlConnection con = new SqlConnection(“Data Source=SourceName;Initial Catalog=DBName;User id=UserName;Password=Password”);
public LoginDetails()
{

//Uncomment the following line if using designed components
//InitializeComponent();
}

// Method to get login records from database
[WebMethod]
public bool GetLoginDetails(string UserName, string Password)
{
// Method not followed any coding standards. This is just for demo purpose

var da = new SqlDataAdapter(“SELECT * from Login where Username =’”+UserName+”‘ and Password=’”+Password+”‘” , con);
var dt = new DataTable();
da.Fill(dt);
if (dt.Rows.Count > 0)
{
return true;
}
else
{
return false;
}
}

}
// Login Class
public class Login
{
public string LoginId = string.Empty;
public string UserName = string.Empty;
public string Password = string.Empty;
}

After creating service just put the reference of that service in that .net application.

flex Code:-

<?xml version=”1.0″ encoding=”utf-8″?>
<mx:Application xmlns:mx=”http://www.adobe.com/2006/mxml” layout=”absolute” creationComplete=”init()”>

<mx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.core.mx_internal;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;

private function LoginUser(event:MouseEvent):void {
ws.GetLoginDetails(txtUserName.text, txtPassword.text);
}
private function GetLoginDetails(event:ResultEvent):void {
// Save a record using a WebService method

if(event.result == 1)
{
Alert.show("login successful");
}
else
{
Alert.show("login unsucessful");
}
}
private function fault(event:FaultEvent):void {
// Oppps some error occured
Alert.show(event.toString());
}

]]>
</mx:Script>

<!– WebService definition –>
<mx:WebService id=”ws” wsdl=”http://localhost:6030/TestWebService/LoginDetails.asmx?wsdl” fault=”fault(event)”>
<mx:operation
name=”GetLoginDetails”
resultFormat=”object”
result=”GetLoginDetails(event)”
/>
</mx:WebService>

<mx:Panel x=”331.5″ y=”166″ width=”270″ height=”150″ layout=”absolute” title=”ASP.NET WebService + Flex Login Demo”>
<mx:HBox height=”95%” width=”95%” horizontalCenter=”0″ verticalCenter=”0″>
<mx:Form x=”100″ y=”100″ width=”100%” height=”100%” borderStyle=”solid”>
<mx:FormItem label=”UserName”>
<mx:TextInput width=”106″ id=”txtUserName”/>
</mx:FormItem>
<mx:FormItem label=”Password”>
<mx:TextInput width=”106″ id=”txtPassword”/>
</mx:FormItem>
<mx:FormItem width=”156″ horizontalAlign=”right”>
<mx:Button label=”Login” id=”btnLogin” click=”LoginUser(event)”/>
</mx:FormItem>
</mx:Form>
</mx:HBox>
</mx:Panel>

</mx:Application>

In the above code put the service reference URL replacing “http://localhost:6030/TestWebService/LoginDetails.asmx?wsdl“.

and run the application you have below screen.

Now you can have UserName : Test  & Password : Test

Then the screen appears like…

and if you enter Username : OtherTest & Password : Test

The screen appears like…

So, this way you can use asp.net web services in the Flex. For more query and details you can contact me or ask me freely.

The below code is for replace the specified attribute from the html.

protected override void Render(HtmlTextWriter writer)
{
using (System.IO.MemoryStream msOur = new System.IO.MemoryStream())
{
using (System.IO.StreamWriter swOur = new System.IO.StreamWriter(msOur))
{
HtmlTextWriter ourWriter = new HtmlTextWriter(swOur);
base.Render(ourWriter);
ourWriter.Flush();
msOur.Position = 0;
using (System.IO.StreamReader oReader = new System.IO.StreamReader(msOur))
{

string sTxt = oReader.ReadToEnd();
sTxt = sTxt.Replace(“rules=\”all\”", ” “);
Response.Write(sTxt);
oReader.Close();
}
}
}
}

If you have the Data in Sql table like

Value

15

17

Now, If you want to print the values like $15 and $17. So you will have to do like this…

SELECT LEFT(‘$’ + CONVERT(VARCHAR, CAST(’15.00′ AS MONEY), 1), LEN(‘$’+ CONVERT(VARCHAR, CAST(’15.00′ AS MONEY), 1)) – 3)

If, you want to remove the textbox auto-complete history from the browser,

then You have to set two properties for text box in aspx File.

Autocomplete=”Off” and AutoCompleteType=”Disabled”

This will dont prompt any previous values of textbox which you entered in the past.

From,

Vinit.

If I want to select only limited(2) items from the listbox then using Jquery use the below code,

<head id=”Head1″ >
<script type=”text/javascript” src=”http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js”></script>

</head>
<body>
<form runat=”server”>
<asp:ListBox ID=”ListBox1″ runat=”server” SelectionMode=”Multiple”>
<asp:ListItem Text=”Item1″></asp:ListItem>
<asp:ListItem Text=”Item2″></asp:ListItem>
<asp:ListItem Text=”Item3″></asp:ListItem>
<asp:ListItem Text=”Item4″></asp:ListItem>
</asp:ListBox>
</form>
</body>
<script type=”text/javascript”>
$(‘#<%= ListBox1.ClientID %>’).change(function()
{
if ($(this).find(‘option:selected’).length > 2)
{
this.options[this.selectedIndex].selected = false;
}
;
});
</script>

</html>

Using Javascript

<html xmlns=”http://www.w3.org/1999/xhtml”>
<head id=”Head1″ >

<script type=”text/javascript”>
function test()
{
var selectedCount = 0;
var listBox = document.getElementById(‘<%= ListBox1.ClientID %>’);
var i = 0;
do
{
if (listBox.options[i].selected)
{
selectedCount++;
if (selectedCount > 2)
{
listBox.options[i].selected = false;
break;
}
}
i++;

} while (i < listBox.options.length)
}
</script>

</head>
<body>
<form runat=”server”>
<asp:ListBox ID=”ListBox1″ runat=”server” onchange=”test()” SelectionMode=”Multiple”>
<asp:ListItem Text=”Item1″></asp:ListItem>
<asp:ListItem Text=”Item2″></asp:ListItem>
<asp:ListItem Text=”Item3″></asp:ListItem>
<asp:ListItem Text=”Item4″></asp:ListItem>
</asp:ListBox>
</form>
</body>
</html>

string link = ds.Tables[3].Rows[index]["link"].ToString();

myiframe.Attributes.Add(“src”, link);
}
}
}

public string str;

now place the str in the aspx file where you need to create the multiple textboxes like this

<%=str%>

now in the button click event using stringbuilder append the code that is used to create the TextBoxes dynamically like this

StringBuilder sb=new  StringBuilder();

sb.Append(“<asp:TextBox id=”xxx” runat=”server”/>”);

like this u can bind number of TextBoxes.

now assign this “sb” to the “str”

str=sb.ToString();

your Textboxes get created in the aspx file.
