You have to start from somewhere, then we can help. If you're thinking of using n-tier, then consider having a data access layer, a business logic layer and of cos your presentation layer.
Again, you have to start something, then if you run into problems we will help

You are talking of cascading dropdownlist, just google 'cascading dropdown' and you will get lots of article on the same with *code* that you want!
P.S.: Even code project is enough for it, if you don't prefer google.

What matters the most when binding data to a control(dropdown in this case) is your datasource,
this will determin how you retrieve data from your datasource to your control, can be a List<>, database, collection.
For instance, i will bind simple data to my dropdown from a ArrayList.
public void FillCustomerNames()
{
ArrayList customerNames = new ArrayList();
customerName.Add("Member123");
customerName.Add("Member1234");
customerName.Add("Member12345");
dropdownlist.DataSource = customerName;
dropdownlist.DataBind();
}
That's it, whenever you call this method from anywhere it will fill your dropdownlist with those values(items)

thank you for your reply, and if I want to show the result of choice in the dropdownlist in a html table creates at run time of this application
here is the code of creating a htmltable to display data from DB SQL by selecting a dropdownlist:
string chaineCnx = ConfigurationManager.ConnectionStrings["ConnectionString_operateur"].ToString();
HtmlTable tbTableName = new HtmlTable();
HtmlTableRow tbRow = null;
HtmlTableCell tbCelle = null;
tbTableName.ID = "TableName";
tbTableName.Border = 1;
tbTableName.CellSpacing = 1;
using (SqlConnection cnx = new SqlConnection(chaineCnx))
{
cnx.Open();
SqlCommand cmTable = new SqlCommand("select * from operateur, cnx);
SqlDataReader drTable = cmTable.ExecuteReader();
while (drTable.Read())
{
tbRow = new HtmlTableRow();
for (int i = 0; i < drTable.FieldCount; i++)
{
tbCelle = new HtmlTableCell();
tbCelle.Width = "80";
if (drTable[i] != DBNull.Value)
tbCelle.InnerText = drTable[i].ToString();
tbRow.Cells.Add(tbCelle);
}
tbTableName.Rows.Add(tbRow);
}
this.form1.Controls.Add(tbTableName);
}

Tell me without use of AJAX i Think it can be possible by adding one more attribute i.e. onTextChange event bt i dont know how i do this.
Guide me if u know the solution

if you wont use AJAX on every textchanged a postback will happen which at all not good
|
|

|

Use Ajax and in Sql Query use Like stmt

Try out! You have been given head start...use Google with key words if needed... people here won't provde you direct code. Put some effort and if you get stuck, all will help.

Yeah, the way out is to use the ajax AutoCompleteExtender alongside a web method to get the data

I tried both of this type, both work for IE and none work for firefox,
but when i paste the second line in the firefox address bar, the file can
open and show my css coding but the 1st line will not show in firefox:
1. <link href="C:/Documents and Settings/Morgan/Desktop/Morgan Documents/PlanetFitness/App_Themes/StyleSheet.css" type="text/css" rel="stylesheet" />
2.<link href="file:///C:/Documents and Settings/Morgan/Desktop/Morgan Documents/PlanetFitness/App_Themes/StyleSheet.css" type="text/css" rel="stylesheet" />
Don't worry with my full file path coz thats what Visual studio wants

I don't know if you are plannimg to use your webpage on a webserver in the future, but I would worry about the full path.Don't mind what Visual studio want, try to fix it.

How can a clever guy like me struggle like this?
You know what? I just changed the whole full path to:
<link href="App_Themes/jtip.css" type="text/css" rel="stylesheet" />
and both firefox and IE can read my css code...
mistakes...
And thanks for being helpful man

I seem to remember that Firefox has a security feature, on by default, to prevent it from reading local files referenced by the link tag. If you avoid calling something a local file you avoid the roadblock, as you found out.
