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?

</td>
When the user clicks the edit button I want to pass the unique identifier from the item in the list to the parameter string so I can retrieve it in the edit page. how to retrieve the ID from the selected item?

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.

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)

{
//lblResults.Text += item.Text + "

Label1.Text = item.Text;

No use, no value coming in to label.

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
i use a dropdownlist in a page, with its items taken from a mysql database
i also use autopostback property...my problem here is that, every time i selecct an item, the first item in the list gets seelected
I have a drop down list control populated with items and some code to take the currently selected item value. The problem is I only get the value of the first item in the list regardless of what item is actually selected. Here is my code to populate the drop down:
protected void displayCreateCategories()
{
StoreDataContext db = new StoreDataContext();
var a = from c in db.Categories
orderby c.Name
select new{catName= c.Name,
catId=c.CategoryID};
ddlCategory.DataSource = a;
ddlCategory.DataTextField = "catName";
ddlCategory.DataValueField = "catId";
ddlCategory.DataBind();
}
To get the value of the currently selected item which in my case is always of type integer I do label1.text=Convert.toInt32(ddlCategory.SelectedValue); I get the selected value, but it is always for the 1st item in the list. I'm pulling my hair out over this.
I have the following DataList control:
[Code]....
When I click on the LinkButton, I want to insert the current item in the DataList into the database via LINQ to SQL in C# code behind. In the codeb behind, how do I retrieve that particular item so I can insert it into the database?
I have a datalist control which is filtered through a query string select parameter for a single product each time
This is on a details page What i want is to dynamically set the page's title according to the selected product's name Something like..... Page Title="<%# Eval("Title") %>"..... but that of cource won't work
I'm using C# for my code behind
I'm creating a forum and the forum posts are items in a datalist.
Now I want to include the nifty feature that when one has replied to a message and the forum thread page is being displayed, the page is autmatically scrolled down to the message one wrote (the same thing goes for linking to a message, one wants the page to be scrolled down to the right place from the start).
I guess this could be done using anchors an html, but is there a function i vb.net that would do this for me?
i'm trying to get a datalist item to string, but i keep getting this error??
Object reference not set to an instance of an object.

i have 3 items in my dataliste but the
Label46.Text = DataList2.Items.Count gives me 2.
