Hi
I have a combobox with data source from dataset.
I recieve the data in Decimal and I want to present it in Hex.

example:

    myCmb.DataBindings.Clear();
    myCmb.DataSource = myDataset.myDataable;
                myCmb.DisplayMember = "myColumnName";
                myCmb.ValueMember = "myColumnName";

I tried to use Format() but the combobox doesnt have this property. it
doesnt work on the combo box.
I am a begginer programmer so I will thank you for a simple
explanation.
Thanks, Orr

I looked for away to format in an event, but did not find one.

You will probably have to use a datareader to loop through the database rows and
add the items to the combobox one at a time after formatting them.

Why do you need to format the items? Are you putting numeric values in a combo
box to be chosen by the user? How will you use the items in the ComboBox?

ComboBox controls are typically used for picking and choosing items from a list
of known values. If you're loading numeric values into one for this type of
activity, you might find that another type of control is a better fit.

Tell us more about what you are trying to accomplish.
Good luck with your project,

I might try an expression in the SELECT that returns properly formatted
value.

Yep, that would work, if the OP can deal with a string. I guess even if they
can't they can convert it to the original type after they take it out of the
ComboBox.
