Jun 14, 2010This code will display the selected value from the listbox. E.g. if I sellect Item 1 I will get the following output: You have selected Item 1.
Label1.Text = "You have selected " + DropDownList1.SelectedValue + "<br />";
But if I don't select anything and click on Submit button, I will get: You have selected
What would I need to make it display "You have not selected anything. select at least 1 item."
UPDATE: I am using ASP.NET WebForms.
Web Forms :: How To Pass The Value Selected From The ListBox To Each Other WebPartSelect Webpart
Feb 11, 2010I have a ListBox in a WebPart called 'WebPartSelect'. This WebPart appears on each webpage.
How do I pass the value selected from the ListBox to each other WebPartSelect webpart?
e.g. the ListBox has 3 values - a, b, c. The user select value b. When they visit another webpage I want the ListBox to be defaulted to their selection - 'b', and to display data relevant to this selection.
Web Forms :: Listbox.Selected - Duplicate Item Error
Nov 4, 2010I have built one of those 2 listbox things where the items in the left textbox can be selected and moved to the right list box. The items in the list can be thought of as tasks (like Raise Invoice, Call Client, Deliver goods etc) The rules of this are that the item you move to the right box remains in the left box. Reason being, you are allowed to add the same item from the left to right as many times as you like. An example what the list on the right might look like is this.
Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal
Now I have added the feature to select an item on the right and hit the UP button, to move it up in the list. For example I could select 'Deliver Goods' and hit the up button. (the down button works as expected)
Raise Invoice
Deliver Goods
Call Client
Installation
Call Client
Finalize Deal
If i select the 2nd instance of Call Client and hit the up button,
Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal
This is what happens.
Raise Invoice
Call Client
Deliver Goods
Installation
Call Client
Finalize Deal
My code that loops though and does the move relies on the item.selected property to find which on I have selected. (obviously)
[Code]....
Despite having the items at the bottom of the list selected, the .Selected property is true on the first instance of the item that happens to have the same .Text and .Value.
Web Forms :: Displaying Data From Selected Item In Listbox
Oct 13, 2010I have a asp.net web form in which I display registered customers in a listbox. In the listbox I can choose one customer, and click a "Show data"-button. That should display all registered data about the chosen customer in textboxes next to the listbox. This doesn't work and I haven't been able to find where the error lies. Instead of displaiyng the data in the textboxes the error message in: LabelNoCustomerChosen is displayed. Could it be that the program doesn't find the customer ID? The string that is displayed in the listbox looks like this: ID Lastname, Firstname

Web Forms :: ListBox Selected Index Changed In A TabControl?
Oct 25, 2010As you can see in the picture below i've got a Page control with inital letters which cotains a listbox showing different wood articles. When i click on a Tab, the selected tab page get's a new Listbox control with the wood articels starting with the selected initial letter.
Creating the listbox:

[Code]....
When i click on a item inside the listbox, following code will be executed:
[Code]....
So far, it works fine for me. But when i change the selected Tabpage, the first SelectedIndexChanged in the listbox in the new shown tabpage is not recordnized. That means i have to select a new item and click on Search = the selected Item is still the item i selected before i changed the tab. Then i select the item again and click on search the index changed is recordnized. So why do i have to click two times on search to get the new selected item after a tab page changed?
Here is the full code:

Web Forms :: How To Show Multiple Selected Items Of A Listbox
Jun 18, 2010I had used listbox control with multiple selection mode. I stored id with comma delimiter in database.
e.g.
1. List Item One.
2. List Item Two.
3. List Item Three.
4. List Item Four.
5. List Item Five.
6. List Item Six.
Suppose user select item 2, 4 & 6. So I will store it as a 2,4,6 in database. This will work fine.
Now in editing I have to shows selection-bar for item 2, item 4 & item 6. So I had typed below source.
string strData ="2,4,6"
if(strData != null)
{
char[] separator = new char[] { ',' };
string[] strSplitArr = strData.Split(separator);
int x = 0;
for (x = 0; x < strSplitArr.Length; x++)
{
// lstWDef_PurchasesEdit.Items[x].Selected = true;
lstWDef_PurchasesEdit.SelectedValue = strSplitArr[x].ToString();
}
}
But with this statement I got only last item id as a selected item with selectionbar. In our example 2,4,6 only item whoseid is 5 got as a selected item.
if i use
for (x = 0; x < strSplitArr.Length; x++)
{
if (lstWDef_PurchasesEdit.Items[x].Value == strSplitArr[x])
{
lstWDef_PurchasesEdit.Items[x].Selected = true;
}
}
if the selected items are serial like 2,3,4 then it is displaying correctly..
if items are 2,4,6 then it is not selecting the items of listbox properly.
Is anybody guide me how to make item 2, item 4, item 5 as a selected item ?
