Multicolumn Listbox

[WRH]

Hello
I want to have a multicolumn listbox. I never used one before
so I looked at a Help example. I set the multicolumn property and
the column width and tested with this example...

this.listBox3.I tems.AddRange(n ew object[]
{
"Item 1, column 1",
"Item 2, column 1",
"Item 3, column 1",
"Item 4, column 1",
"Item 5, column 1",
"Item 1, column 2",
"Item 2, column 2",
"Item 3, column 2" });

It works perfectly, with column 1 items is column one and column 2
items in column 2. Now here's why I posted...I don't understand the
example! What is there that results in a two column list with 5 lines
in column 1 and 3 lines in column 2?

Re: Multicolumn Listbox

Hi,

Each object is a comma separated list of values so I assume that the listbox
expect that you define the columns that way.

You failed to mention if this is a web or a win example ( I assume that a
window)

Re: Multicolumn Listbox

Thanks for the quick reply.
Further testing shows that the last 3 items went into column 2 only
because of the height of the listBox (No vertical scroll) What I want
is to specify the column for an item.

Re: Multicolumn Listbox

Hi,

You have to read the docs and see what format ListBox expect for
multicolumns lists.

I just found the txt:
A multicolumn ListBox places items into as many columns as are needed to
make vertical scrolling unnecessary. The user can use the keyboard to
navigate to columns that are not currently visible. Set the
HorizontalScrol lbar property to true to display a horizontal scroll bar that
enables the user to scroll to columns that are not currently shown in the
visible region of the ListBox. The value of the ColumnWidth property
determines the width of each column.

Re: Multicolumn Listbox

Thanks again for the info.

I have decided to use ListView instead, as it seems much
more manageable with regard to columns.

I could not be sure what the user may see at any given
time with a multicolumn ListBox!

Wise decision, Listview is the control for that.
