ListBox DataSource DisplayMember Property
Problems in C#
I have a (single select) listbox with data and
when I click on the list I can't get the right
text selected.
My listbox is setup using the DataSource property.
I set my ValueMember and DisplayMember
listBox1.ValueMember = "TypeID";

Hi, I have a listbox with displaymember that I combined 3 columns together.
After the user made the selection I then need to get each one the of the
selected valuemember but then I don't want the displaymember. I only want 2
of the columns of that made up the displaymember. How can I refer to the
column value in each of the selecteditems?
Thanks, Alpha
strJoinTable = "";
strSelectedIDs.Append(" and l.jcodeID in (");

Hello,
I have a listbox which is bound to a datatable. I have set the displaymember and valuemember and all works well:
the user dbl clicks an item in the list box, I use the valuemember to retrieve some values. However, I would like
a label to display the displaymember value that was selected by the user. I am assuming this is a datarow(?).
How does one do this? Below is my code for populating the listbox:

How would you add an item with its DisplayMember and ValueMember without
binding to a datatable or dataview like:
listbox.DisplayMember = "name";
listbox.ValueMember = "recid";
listbox.DataSource = dt;
listbox.Items.Add(name) can only add the DisplayMember.
Thanks,

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.
Here is my compilation command:
