reading XMl through javascript and populating into a combobox

use this...
<object style="width: 247px; height: 118px">
<param name="movie" value="1.swf" />
<embed height="400" src="1.swf" width="550" />

Server Transfer problem

I have an asp page posting session variables to my ASP_NET page
the _NET page recalls the variables and is meant to server transfer
the string to another page. When I substitute Response_redirect , the code behaves
wonderfully . I think my variables are still Integers not strings ??

<%@ Page language="VB"  debug="true"%>
<script runat=server  >
Sub Page_Load(sender as Object, e as System.EventArgs )
Dim i as Integer
for  i  =0 to Request.Form.Count -1
Session(Request.Form.GetKey(i))=Request.Form(i).ToString()
Next
dim pId 
pId = Session("prodId")
pId =  ("?search=" + pId)

Server.Transfer(Session("DestPage") & pId.ToString() ,true)
End Sub
</script>

HttpException (0x80004005): Error executing child request for description.asp.]
System.Web.HttpServerUtility.ExecuteInternal(String path, TextWriter writer, Boolean preserveForm) +1828
System.Web.HttpServerUtility.Transfer(String path, Boolean preserveForm

Many Thanks, Bev

Re: reading XMl through javascript and populating into a combobox

16-Feb-09 1:54

Hi,

I have a combobox cmb and a xml file like

<?xml version="1.0" encoding="utf-8" ?>
<NAME>
<NAME POINTS="1.5" value="a" />
<NAME POINTS="1.0" value="b" />
<NAME POINTS="1.0" value="c" />
<NAME POINTS="1.0" value="d" />
<NAME POINTS="0.5" value="e" />
<NAME POINTS="0.5" value="f" />
<NAME POINTS="0.5" value="g" />
<NAME POINTS="0" value="h" />

</NAME>

in the body onload ,a function is there abc()
in the time of page loading i want to fill the combo with a,b,c....to h and they have the curresponding numeric values as mentioned in the xml

And if we write document.form1.cmb.value ,it will dispaly the numerical value,instead of that i want to get the text value only to a string.

Thanks in advance!!!!

Can`t you use XmldataSource that comes inbuilt in VS 2005. All you need is to give the path of you xml file and bind this datasource to your dropdownlist.

val=document.getElementById("My_DDl").selectedIndex;
var selectedText=document.getElementById("My_DDl").options[val].text;

So there are two ways... either you hard code your values in the dropdownlist or use
AJAX to read the xml file and then fill the data fetched in you dropdown.

this[^] might help you.

session value and using that

hi people

I've created this session in global.asax part of my project in this way:

Session["news_id"]= null;

I've used a datalist to load some news titles from database and when you click on that title (Which is a link button) there opens a popup window and reads the desired news.
It the click event of mentioned link button I've told that:

Session["news_id"]= (int)(dataList1.DataKeys[dataList1.SelectedIndex]);

(I guess that the snippet above is problmatic)

Then in the form_load of that popup page after creating the sqlconnection stuff i've made the below commandtext:
"select text from news where id='"+Session["news_id"]+"'";
in which text is a field that news is stored and news is the name of my table.
What I get as an error is that sometimes on the click event of my link button says : Object not set to its refrence or something and sometimes it says that index was out of range!

Plase help me with you solutions.
Thanks alot

You are right, i also think the problem with

Session["news_id"]= (int)(dataList1.DataKeys[dataList1.SelectedIndex]);

First, dataList1.SelectedIndex is start with 0 and i think news_id is start with 1 (Its my guess).

This index of control never be similar with your id. you can use response.write to check this problem...

You can also use the similar type of things....

<asp:datalist id="DataList1" runat="server" backcolor="White" bordercolor="#E7E7FF" xmlns:asp="#unknown">
BorderStyle="None" BorderWidth="1px" CellPadding="3" DataKeyField="id" DataMember="DefaultView"
DataSourceID="SqlDataSource1" GridLines="Horizontal" UseAccessibleHeader="True"
Width="100px">
<itemtemplate>
]]>
]]>

<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:ConnectionString %>" xmlns:asp="#unknown">
SelectCommand="SELECT [id], [title], [name] FROM [table]">

Here you pass news id as query string.

As a matter of fact the result of return is always -1 ! I don't know why.
by the way Do you think I can try the title instead of id?
I mean I use the string of title to pass to session and ...

by the way, since I am kind of new in asp.net please inlight me with the ways you've provided. I have no idea what I should do with them

thanks

16-Feb-09 2:43

You can pass anything instead of id which is unique (because every link open a unique page.). you can use javascript window.open() function also to open in pop up.
In pop up page you receive the id/title value and based on that value you can show the content in the pop up.

you may use a JS function which will be triggered on key press. When handling the OnKeyPress event, you need to check if the pressed key is Enter, if yes, you need to call btnLogin.Click(); (btnLoginId is passed as a function parameter)

onkeypress="return Login(event, 'btnLogin')"

function Login(e, btnLoginId)
{ 
      var evt = e ? e : window.event;
      var btnLogin = document.getElementById(btnLoginId);
      if (btnLogin)
      { 
          if (evt.keyCode == 13){ 
                btnLogin.click(); 
                return false; 
          } 
      } 
}

Dim treenode As New TreeNode()
Dim secondnode As New TreeNode()
treenode.Text = "This is first node"
secondnode.Text = "This is sub node."
treenode.ChildNodes.Add(secondnode)
TreeView1.Nodes.Add(treenode)

End Sub
