Dropdownlist problem

[cyrus_]

Hi, I have been working with my project for 2 weeks but i have failed everytime, The problem is i want to catch the selecteditem in my dropdownlist but it is just the first item everytime,here is my code: protected override void CreateChildControls() { DDL = new DropDownList(); DDL.Load += new EventHandler(DDLLoad); DDL.SelectedIndexChanged += new EventHandler(DDLItemChanged); Controls.Add(DDL); } protected void DDLLoad(object sender, EventArgs e) { DS = GetChannels(); if (DS.Tables.Count > 0 ) { DDL.DataSource = DS; DDL.DataTextField = "title"; DDL.DataValueField = "title"; DDL.DataBind(); } else { MessageLBL.Text = "Unable to connect to the database."; } } protected void DDLItemChanged(object sender, EventArgs e) { string mytitle = DDL.SelectedValue; MessageLBL.Text = mytitle; //here it is always the first item }

When you select an item in the DDL does it postback?If it does it is reloading before catching the value, that is why you always get the first value.Try this

protected override void CreateChildControls(){  if(!IsPostBack)  {    DDL = new DropDownList();    DDL.Load += new EventHandler(DDLLoad);    DDL.SelectedIndexChanged += new EventHandler(DDLItemChanged);    Controls.Add(DDL);  }}

A postback is basically a page refresh.When you press your button the page refreshes doesn't it?

<{POST_SNAPBACK}>

yes it is

so if you use this code it should work

protected override void CreateChildControls(){ if(!IsPostBack) {   DDL = new DropDownList();   DDL.Load += new EventHandler(DDLLoad);   DDL.SelectedIndexChanged += new EventHandler(DDLItemChanged);   Controls.Add(DDL); }}

thanks again, when i use your code my drondownlist is empty first time the page will be refresh, (It has items just first time)

is it completely necessary to create the DDL dynamically??? It makes things more complicated...if it doesn't you should not do it dynamically.
