Hello All,
I have a Repeater which contains a Dynamic DropDownList within its
itemtemplate. I know I have struggled with this before and I am pretty sure I
had to save a bunch of crap manually to the viewstate, but does anyone know
what would cause those DropDownList objects to clear out on postback. Is
there a setting on the Repeater I am forgetting about? I tried tooling with
EnableViewState but that did not work. The Repeater gets filled only in the
!PostBack onLoad event, and the DropDownList objects are filled initially in
the ItemCreated event of that repeater.
Within the Repeater there is also CheckBox objects, which etain state fine
and PlaceHolder objects which Visibility gets reset onPostBack. It is driving
me nuts, I could have sworn there was something that would let me fill the
Repeater once, then access the values selected by iterating the RepeaterItem
objects. Here is the pseudocode because the regular code is way too long to
post:
onLoad {
if (!isPostBack) FillRepeater();
}
Repeater.onItem Created {
FillDropDownBox ()
}
Button.Click {
for (int i=0; i<Repeater.Item s.Count; i++) {
selectedVal =
Repeater.Items[i].FindControl("D ropDownBox").Se lectedValue
}
}
That is pretty much what I was doing but when you postback because the
ItemCreated wasnt fired, the DropDownList is empty, furthermore, if I rebuild
the Repeater prior to trying to access its details we would lose all of the
changes the client made.
Any ideas anyone? 1 2702
Nevermind I had to use Request[] to get the data and rebuild the lists when
necassary.

I have a dropdownlist which lives inside of a repeater. The repeater
accepts user input via textboxes and the aforementioned dropdownlist.
The repeater accepts phone numbers and allows for an arbitrary number
of empty rows to be added to it.
So, if a user knew in advance that they wanted to add 3 phone numbers,
they can type the nuber '3' in a textbox (outside the repeater)
and click a button (also outside of a repeater), and 3 new empty ...

Hi There,
I am developing a shopping cart web application in C#. Product
pricing for an item changes based on the weight of product purchased.
ie: 100g=$4.95, 200g=$7.95, etc. Pricing is different for each
product.
When viewing the cart, I would like the the user to have the ability
to select a different weight, specific to that item, which would then
modify the price of that cart item.

Hi all,
I am creating a DropDownList in a RepeaterControl. After the Repeater is
DataBound in the ItemCreated event (of the Repeater) I bind the DropDownList
to a Table and then try to select one of its value. Here is the code:
If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType =
ListItem.AlternatingItem Then
Dim ddl as DropDownList = Ctype(e.Item.FindControl("ddl"), DropDownList)

I have a (.Net 1.1) form with a Repeater and a DropDownList in the
ItemTemplate. I programmatically make the DDL Autopostback = true at
runtime based on the bound data. That works - I can see the postback
happen appropriately.
The DropDownList looks like this:
<asp:DropDownList id="ddMultiQty"
OnSelectedIndexChanged="ddMultiQty_SelectedIndexChanged"
runat="server"></asp:DropDownList>

Hi
I am trying to place three DropDownLists inside a Repeater, each DLL is dependent on it’s previous DDL’s selection. I’m developing in asp.net and VB.
An Initial DDL (inside the repeater) needs to be populated under Page_load () through a stored proc, the selection from this needs to fire another stored proc and populate it’s child DDL. My main concern at this moment is how to populate the first DDL under page_load. I am able to do this...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
