Forms Data Controls :: Add ListItem Programatically With On Item Selected?
Jan 22, 2011
I have a DropDownList on my aspx page and wanted to add ListItem programatically. The item will start from 2 years ago to 1 year later (e.g. from 2009 to 2012) so if the year change, it will be automatic. I also want the current year to be selected by default.
In the code behind, I did this:
For i As Integer = (DateTime.Now.Year - 3) To (DateTime.Now.Year + 1)
DropDownList1.Items.Add(i.ToString())
Next
DropDownList1.SelectedItem.Text = DateTime.Now.Year
As result, I'm having the items in this order: 2011 (selected), 2009, 2010, 2011, 2012. The 2011 is duplicated (I wonder why). When I view the source page on Internet Explorer, I have this:
<option selected="selected" value="2011">2011</option>
<option value="2009">2009</option>
<option value="2010">2010</option>
<option value="2011">2011</option>
<option value="2012">2012</option>

How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.

have a nested listviews:
Listview1-Item1
<if Listview1.selected index = 0>
Item1NestedListView - item1
Item1NestedListView - item2
When a user selects an item in the parent listview, the nested listiview displays as part of the selected item template - when a user selects an item in a nested listview it correctly populates a third, separate listview. To make sure I'm being clear, I have a parent listview with many rows and each of those rows has a nested listview, that is only populated and displayed when the row is selected. The parameters for the nested listview are set in the ItemDatabound event of the parent.
I had this working fine when both objectdatasources were on the aspx page. However, requirements have changed and we would like to pass a class to the BLL. I cannot figure out how to do this using a datasource on the aspx page. I can pass a class doing a databind in the code behind. However, if I do the databind in the code behind, the SelectedItem template does not get displayed as I would like. I need to find the the selectedIndex for the parent listview in SelectedIndexChanging. however, when I click or 'select' an item in the parent listview, the page refreshes, the ItemDatabound of the parent of the parent fires NOT knowing the selectedindex, then the SelectedIndexChanging event fires changing the SelectedIndex. By this time the Listview is already on the screen without the selectedItemTemplate containing the nested listview. If I click on another item, the when the page refreshes it knows the selectedItemIndex chosen before and displays that SelectedItemTemplate containing the selected index.

I have 2 radiobuttonlist in a web forms, each contains of 4 ListItem. So there are 8 ListItems in total. It is initialised such that none of the ListItems is selected. I want to validate that at least one of the ListItems is selected when submit button is pressed. How to do it? i.e. at least 1 ListItem is selected, either from radiobuttonlist1 or radiobuttonlist2.

I have one ListView. If someone selects an item (as LinkButton) in the ListView, then the program will retrieve the record value and then converted the record value into ArrayList.
Is there VB code example (or showing a link) how to write the program in one page aspx?

i have a listview. The listview contains a usercontrol with ID="ucEquationBuilder1" which is added only! in the SelectedItemTemplate.I've came along some post which stated you can't find the control in the SelectedItemTemplate unless it is also in the the ItemTemplate.
To me this sounded ridiculous. Untill i ran some tests, and indeed i was able to find all other controls (TextBox's Labels) which where both inside the itemtemplate and the selecteditem template.
To me this is quite frustrating. Is there a way to retrieve the control which is only inside the SelectedItemTemplate without adding it to the itemtemplate?

I have a ListView which I populate using DataTable.
In each row I have a delete button. When the user clicks on the delete, that particular row is deleted in the DataTable Table.
After I perform the delete, I want to avoid page reload just to populate the ListView with the new set of records without showing the deleted row.
I suppose LINQ is the best choice for this. But I am unable to implement it.

I'm currently working on a project and I want to make as much things as possible performing on client side - with as little loading as possible. The project consist of three "main" pages. On one page I use jQuery DataTable plugin which is working great. One page has tabs (using jQuery). I want to put datacontrol (repeater) on this site and when user selects one item in dropdown, data in repeater loads on client side, without performing the action on server.

I have a HyperLink control in a ListView, and I need to pass a couple of querystring parameters.
[Code]....
The first parameter is based on the current DataItem value in the LV.
Suppose I want to set a second parameter with a value from Selected.Item.Text in a DropDownList on the same page, how would the HyperLink look?

What I want to do is insert a database NULL instead.

I have one repeater on page which has his own sql data source. I've placed 2 dropdown lists on the page. The repeater has jQuery DataTable plugin. With 2 dropdownlist I wish to change the sql stored procedures so when each will be selected the data in repeater will change. When user select the first there will be only data (users) according to selected item and in the second the same. I wrote 2 simple functions for changing stored procedure of repeater and rebiding it. Everything works but when I try the second one and then the first I always get warning about error "Procedure or function .... has too many arguments specified".
I think that when I select the first one the second function is still called although I don't call it.

I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
