it must be tempting to say FTFM, but believe me I have.
I have a combobox.
I set Co.ValueMember = "field1"
and Co.DisplayMembe r = "field2"
and then load some data this way
Co.DataSource = DS.Tables(1)
so far so good, I now have a combo filled with data.
Now all I need to do is move the combo to an item with code, based on
the ValueMember.
I guessed something like
Co.SelectedValu e = "123"
No joy. I have loads of other things as well.
Any tips? 5 997

if anyone is interested, I have found the answer to my problem!!!
Co.SelectedValu e = "123" does indeed work,
However, if you create a new combo at runtime, set the selectedvalue,
and then add it to the form, it fails. If you create a new combo at
runtime, then add it to the form, then set the selectedvalue, it works
fine!
Not sure if this is obvious behaviour or not. Oh well, I'll file it
under Q for quirky.
You can select a item by its value like this:
Me.comboBox.Ite ms.FindByValue( YourValue.ToStr ing()).Selected = True

I belive the drop down list doesn't bind to its data until it's been added to a form. A limitation due to
BindingContext? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Let's say in the product table I have around 50,000 products (well,
infact it has now about 2000 only, but it's growing very fast, hence
the question here)
In the order form, users will select the product for the order lines.
They want to see the entire list of available products.
You can't handle the combo the way you've heard: limiting rowsource
until first few characters entered, because

Can anyone tell me how the initial value displayed in Combo Box is

I am loading the dropdown from one field ("CategoryName") of a table, with

I expected.
The field "CategoryName" is not the primary key for the table -- the PK is

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.
