I have a DataGrid (WebForm - C#) that has a template column that contains a dropdownlist named "DdlTest"
In DataGrid1_UpdateCommand, the lin
DropDownList ddlTest = (DropDownList) e.Item.FindControl("DdlTest")
enables me to work with ddlTest - with, for example, ddlTest.SelectedValu
However, in DataGrid1_EditCommand, ddlTest.SelectedValue returns "Object reference not set to an instance of an object.

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

Hi,
I have a dropdownlist in my DataList control and I am trying to set the
SelectedItem property of the dropdownlist so when the datalist displays
the user will see the text in the dropdownlist set to a predetermined
value.
I can set the SelectedItem property easy enough and get the
dropdownlist to work fine just so long as the dropdownlist is just on
the form itself not in a DataList control.

I can get the dropdownlist into the datagrid, and I can populate it, but I
can't read it.
Anybody have a working example of a dropdownlist in an editable grid?
Thanks.

I would like to open a new window to a url that I have set as the dropdownlist.selectedvalue on the selected index change event. The selectedvalue is the url path and it will open in the existing window. I've tried window.open before the url, but that doesn't work.
protected void DropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
Response.Redirect(this.ddl.SelectedValue);

I have a DropDownList in an ASP.NET web form that is populated with items
from a lookup table by binding that DropDownList to a SqlDataSource.
However, the items in the lookup table can change over time. The problem is
that when an item has been removed from the lookup table, and a user wants
to retrieve a record that used the deleted item, the following error occurs:
'ddlAssignedTo' has a SelectedValue which is invalid because it...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

This is as boiled down as I can make it.
Here is my compilation command:

Overview:
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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
