Hi
I need to write a loop to loop all items in a listbox and run a query for each one.
i have this so far:
for (int i = 0; i < departments.SelectedItem.Selected; i++)
{
}
but its not working, i basically need this
for each row which is selected run query
any help would be great
thanks!

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.

foreach (ListItem item in departments.Items) {
if(item.Selected)
}

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

ListItem has Text and Value properties which can be used.

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.

ok sorted it:
string string1 = departments.Items[i].Value;
cheers everyone!!!!

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.
EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.

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.

hai friends
i written a javascript code in a page
and to call it i used the code
Page.ClientScript.RegisterStartupScript(Me.GetType(), "close", "tranRightt('upload');", True)
its working in my localhost
but when i uplaod the page into website it is not working
plz help me
thanks in advance

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.

Yeah, I usually remember to say that, that's excellent advice. Firebug rocks.

Yes. It rocks. But I am worried, it's showing some weird behavior in FF3.
