Do you mean your listbox has only one item and that is xxxx,yyyy,zzzzz...
And you want to get individual values like xxx and yyyy e.t.c

You question is not clear. You need to clarify.

Firstly, when you hover over my comment, you will see a reply link. Use that to reply otherwise I do not get notification for you comment.
Your question is still not clear. "listbox1.text i wrote but its showing null" means the items are not getting added to the listbox. Debug the code line by line and keep a watch on the required values. If you still can't solve it, paste the relevant code here.

string x = ds.Tables[0].Rows[0][0].ToString();
string get_value = ListBox1.Text.ToString();
con.Open();
DateTime dt = Convert.ToDateTime(DateTime.Now.ToString());
SqlCommand cmd = new SqlCommand("insert into struserquerysend values('" + int.Parse(x) + "','" + Session["UserName"] + "','" + get_value + "','" + dt + "','" + str_color + "')", con);
cmd.ExecuteNonQuery();

listbox having item xxx,yyy,zzz............

Use 'Reply' button as I told before. I do not get any notification if you directly add a comment.

"string get_value = ListBox1.Text.ToString();"
ToString() is not required here. Text property already returns text.
As Sandeep suggested, if may not have selected any value which is why it is returning null.

Solution 1

~~This is because Listbox does not expose a 'Text' property directly.~~

You need to access as: myListBox.SelectedItem.Text
I found a good article to exaplin it's use here: ListBox Control Overview[^]

In your case, there is only one item and if selected then the way to get it is from selecteditem property. In case it's not selected and yet you want to access it then use item proerty with proper index.

Have a look here for all details of listbox properties[^] exposed.

UPDATE:
Listbox.Text would give you 'Selected Value' of the list. It looks like nothing is selected and thus you are not getting anything. In that case, you need to go via item and index as I mentioned above.

"This is because Listbox does not expose a 'Text' property directly."

It does. And it will return the selected value of the control.

:) thanks man!

with out selecting we can't get listbox value.........?

Sandeep Mewara 22-Jan-11 1:56am

I said, you can... you have to use listbox.Item property with index.

Ankur^\m/ 22-Jan-11 2:05am

Okay, tell me how do you need the value?
Option1: value1, value2, value3... OR,
Option2: value1 OR,
Option3: any particular at a particular index?
