I have a repeater control:
<asp:Repeater ID="rep" DataSourceID="XMLDSCompare" runat="server">
<ItemTemplate>
<h4><%# XPath("title")%></h4>
</ItemTemplate>
</asp:Repeater>
Now if its the first item in the total resultset, I want to add <div> to ItemTemplate control, if its the 2nd item, I want to add </div>
So output would be (not including table tags generated by repeater control):
<div>
title 1
title 2
</div>
<div>
title 3
title 4
</div>
<div>
title 5
title 6
</div>
How would I do this in the ItemDataBound event of repeater control?
I have a list item collection. How to add this list item collection to a datatable.
The list item collection has the following fields:

John 35
I want to create a html table from the data table, which is grouped on the Student Name field.
I inherited an application written for VB.Net and am converting it over to ASP.Net, with VB as the back end. I have a data pull that adds values to a new instance of a class, then adds the item to a listbox. It worked great in the VB.Net version, but I get the following error in the Visual Studio Text Editor when I try to use the code:
Overload resolution failed because no accessible 'Add' can be called with these arguments:
'Public Sub Add(Item As System.Web.UI.WebControls.ListItem)':Value of type 'MyItem' cannot be converted to System.Web.UI.WebControls.ListItem'.
'Public Sub Add(Item as String)':Value of type 'MyItem' cannot be converted to String.
I have played around with the code quite a bit and have been researching online, but I'm just drawing a blank here.
I put the class("MyItem") in the "App_Code" folder in a file called "MyItem.vb". The class code is as follows:
[Code]....
The code I have for the sub that is supposed to add the items to the listbox is as follows:

I have a DetailsView that binds a User's Profile data into an ItemTemplate upon the Page_Load. When the user chooses Edit Mode, all of the Data is correctly carried over, except for the DropDownLists selected values. If on the ReadOnly page, the user's data shows "Male" for the Sex, then on the edit Mode page, I would like the DropDownList that gets the sexes from the database ("male", "female"), to have automatically selected "Male" in the DropDownList, not the lowest indexed item.

I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
I am using list view to display the the data but i am getting an error like An item placeholder must be specified on ListView 'ListView1'. Specify an item placeholder by setting a control's ID property to "itemPlaceholder". The item placeholder control must also specify runat="server.Even i have specified the itemplaceholder id but no use still same error.

I have created the following select list item on a controller. code goes here........
select new SelectListItem
{
Value = c.Status_ID,
Text = c.Status_Description
};
And i made the required modification to the view and the select list was displayed successfully.But i faced the following two problems:-
1. i need to use the same select list in more than one controller , so for now i have to insert the same code in each controller to add the select list, so is there a way to define this select list in one place and then reuse it in all the related controllers
2. when i select a new value from the select list and i click on save button , the old value for the list will still be displayed ,and also no effect to the DB will be made.
I have written the piece of code below to get a productID from a gridView when the user clicks on the select link.
Convert.ToInt32(GridView1.SelectedDataKey.Values["productID"])))
However, if a user clicks on this more than one click the newer value replaces the previous. Is there a way to keep adding to the cart list when the user clicks on a new item?
Edit:
Here's my code for the Shopping Page:
[Code]....
I dont know if the location of creating the list is important? Wasn't sure if it was placed in the click event if it would keep creating a new instance?
Then for the Basket Page I have:

In a gridview i have a TemplateField containing a radioButtonList. I have around 100 rows with data and each radiobuttonlist has around 5 options. I would like to have the user to select an option from the radiobuttonList and then in my button click event to record the selected value of the radiobuttonlist for each row. The area im struggling with is how could the click event of my button send the selected value for each row?
View 3 Repliesi have a dropdown list with values
America
Asia
Europe
I need to the display the ddl as Select Type and when i click the dropdownlist to see the values in it, it should display the three values, but i should not use Select Type as a list item and it should not be displayed in the list. It should only be used as a default text in ddl.
I have 2 dropdownlist controls (ddl1 and ddl2). When I pick an item from ddl1, it will update ddl2. The problem is when I pick an item in ddl2, it always selects the first item in the list. Is it that the ddl2 autopostback causes the first ddl1 to reload and results the ddl2 to be refreshed also? Or I didn't set something correctly?

I have a form with two GridView controls and a FormView control. All the data is populated using a SqlDataSource for each control - I'm not using any code behind to populate the controls. So far so good. The first GridView is called grdTrades with code like this:

At the moment when the page loads, the frmOrderDetails FormView is not populated. The user has to click on an order in grdOrders to populate the FormView. Is there a nice way to do this?

I have a gridview with two columns (item templates) one is a dropdown and the other is a textbox. I need to select an item from the dropdown (which I can do) and then get the cost of it and then put the cost in the texbox item template of the gridview. So I think I need to pass the row number and cost_id of the selected item to a procedure to get the cost of the item. Here is my so far code that I have now Idea how to pass the values of the gridview and then pass the cost of the item back to the proper row and textbox of the girdview.

I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.
