Hi,
Even tough I was able to implement what I want in a weird and non efficient
way, I would like to get an opinion what is the right way to achieve my task:
Scenario:
• Display a DataGrid that contains rows from a table from a databse (so far
easy).
• I would like to add a column to the DataGrid that will be a drop-down list
so the user will be able to select a value from a pre-defined list of values
for every row in the DataGrid. (every row should have a drop-down)
• When the user will post back the form I would like to refer to every value
in the drop-down list by name.
• In order to implement this I used a TemplateColumn in the DataGrid, but I
had a hard time giving a name to the <select> element so I will be able to
refer to it when the form will be posted back. I have used a weird syntax
(with data binding syntax since the container is not the DataGrid but a
DataGrid item) to create a unique name for each one of the <select> elements.
This caused the Design-View in Visual Studio to not be able to display the
page even though it did work at run time.
Somehow I feel that I took the wrong way to display a drop-down for each and
every row in the data grid.
Any opinions?

i thing simpliest way is to use DropDownList instead of select control
your code may be like this:
<asp:datagrid id="mygrid"
....
<ItemTemplate >
<asp:DropDownLi st id="MyList" runat="server" />
<ItemTemplate>. ..
and in your postback handler you can use:
foreach (DataGridItem item in mygrid.Items)
{
if (item.ItemType = ListItemType.It em || item.ItemType =
ListItemType.Al ternatingItem)
{
DropDownList list = item.FindContro l("MyList") as DropDownList;
...
}
}

I have a framed page, with a 100 pixel deep header section.
I've coded the JSCookMenu in that frame, but the drop downs get cut in half
..... ie. the drop downs only display within that frame and won't overlay
over the frame below.
Is there any way round this??
I'm not a Javascript programmer, so any coding changes need to be fully
explained please.

I am currently experimenting a bit with
AxMicrosoft.MediaPlayer.Interop.AxWindowsMediaPlayer and so far, most
has gone well.
Currently, i would like to add drag-and-drop functionality to the
program, but the ActiveX has no support for it, so trying to use it
just causes error's.
What i have done is use a small label that i use for displaying current
progress in the media file to use the drag-and-drop functionality.

I've googled and tried various approaches, but could not resolve this
problem. The article at MSDN: Displaying Images in a GridView Column
only presents a simple case where all data (including the images) of
the gridview come from a single table/datasource.
Here is my situation. In my web application, I need to display
customer bills info in a gridview.
Customer names and contact info are from the Customer table.
