There's no listbox in ASP.NET ?

use foreach to iterate over the selectedItems, or use a for loop that goes through all the items and checks which ones are selected. What you've written surely won't compile ?

There is one. Check this[^], or am I missing something ?

OK, I didn't think it was called that as an ASP.NET control. I'm wrong, I admit it.

Yep ive got that now:

for (int i = 0; i < departments.Items.Count; i++)
{
if (departments.Items[i].Selected)
{

but how would I set the value selected from the listbox would it simply be

departments.SelectedValue?

thanks

Ok, Ive tried this:

ListItem item = departments.Items[i].Value;

but get the error:

Cannot implicitly convert type 'string' to 'System.Web.UI.WebControls.ListItem'

I cant find the correct syntax to set the item value.

You are totally lost. Value returns string not ListItem. It should be

ListItem item = departments.Items[i];
item.Value

use foreach as I shown in my first post. foreach is cleaner than this.

Its wrong, the 'Selected' property returns a boolean value.

As CG said you can use Foreach to loop throught all selected items,
OR a for loop to loop through all items and find selected items.

onkeypress is the JS event. Hook your event handler to this event. Put your code into a JS function and hook it with onkeypress event. Something like

YourTextBox.Attributes.Add("onkeypress","YourJsFunction();")

You have web.config file opened in the editor and it is asking confirmation to reload when the file changes. It's not ASP.NET issue, this is how VS editor works.

I don't recommend writing to web.config at runtime. When web.config file changes, application has to recycle and it will destroy current sessions. I'd use a separate configuration file other than web.config if connection strings are being updated on runtime.

What does 'not working' mean ? Your question header shows wrong thinking, if you inject script in the page, it will attempt to run. I would assume the issue is that the js file containing tranRightt is not loading properly due to issues in how you include it, and your folder structure when you deploy.

Adding to what CG said: install firebug which is an extension for firefox and debug your JS.

in RadioButtonList
how to get Text and Value of ListItem
when we check any one using java script function

var s = document.getElementById('<%=rbtnHeader.ClientID%>').value;

so how to do?

thanks

RadioButtonList is rendering as radio buttons with html table.
So you cal add an onclick event to the asp:ListItem Something like below.

<br />
<asp:listitem text="T1" value="V1" onclick="GetVal('rbtnHeader_0');" ></asp:listitem><br />
<asp:listitem text="T2" value="V3" onclick="GetVal('rbtnHeader_1');" ></asp:listitem><br />

and the js is

<br />
function GetVal(cntrl)<br />
        {<br />
        var x=document.getElementById(cntrl);<br />
        alert(x.value)<br />
        }<br />

I dont know how good this is.But It will work.
