Dropdownlist with 2 colums

[IlseDC]

On my webform I have a dropdownlist.
In this dropdownlist I want to display ID and description.
In my datasource I made a field ID_Description:
ID_Description = ID.trim() + " " + Description.trim();
I used this field as DataTextField in the dropdownlist.
Problem: ID and Description have not the same alignment for all items because the length of ID is not the same for all records. I don't want to use a fixed font.
So I want to display ID and Description in two colums in the dropdownlist.
Is this possible?

Thanks.
Ilse

It isn't possible with the standard drop down list (although it could be extended to do so but that would involve a fair amount of work). The other options you have are:

1) Use a 3rd party control (there are quite a few that offer that functionality).
2) Pad the id so that they are all of equal length

Padding the id is not a good option when you use a non-fixed font (Arial, Verdana, ...).
When you pad the id you have to use a fixed font (Courier).
A fixed font is also needed because f.e. character W is larger than I.
But I don't like fixed fonts.

If you don't like fixed width fonts, you may have to go with a 3rd party control.

hi

why don't you just create a function which fills up with spaces , let's say (max - ID.length)x(spaces) + Description
, where max= 20 (or 30..)

int max=30;
string tmp = ID;
for (int i = 0;i<(max-id.length);i++)
tmp+=" ";

tmp+=Description;

To fill up with spaces works only if you use a fixed width font (courier).
In proportional font (arial) the characters don't have the same width so the alignment of description will not be the same for all items.
I would like to have two columns but with a proportianal font not a fixed width font.

3rd party control then...
