[C#] Change color of items in CheckedListBox

[robotnic]

Hello

I want to change the color of items in a CheckedListBox control

- so that i'll be able to choose what color i want for each item.

How can i do it?

thanks.

To do this, your item must be a htmlcontrols.htmlselect NOT a webcontrols.CheckListbox

Like <select id="ddlListBox" runat="server">

this.ddlListBox.Items[this.ddlListBox.SelectedIndex].attributes.add("style","background-colour:red;");

or

this.ddlListBox.Items[this.ddlListBox.SelectedIndex].attributes.add("class","RedBox");

lunamonkey, you are first indeed, but this does not help me, since i'm using WindowsForms and not WebForms

Sorry dude, got carried away with web stuff.

Might not be possible with windows forms... there's no attributes or anything.

I think lunamonkey is right here. Usualy, in Rich Edit boxes and similer controls, you can select certain parts of the text and change their attributes. Ive been messing around with the control a few mins, and couldnt find anything changeable in a single item class.

One method I have used in the past (ListView) is to override the onPaint event

and use GDI to paint the contents of the cell with the colours I want.

Its a little convoluted; but it does the job.

Can you use a ListView control with the CheckBoxes property set to true and View property to List, instead of using the CheckedListBox control?

In that case, there should be a pretty "clean" method, like this:

ListViewItem lvItem = new ListViewItem("Bla bla");
lvItem.ForeColor = Color.Yellow;
lvItem.BackColor = Color.Black;
listView.Items.Add(lvItem);

Otherwise, yeah, overriding controls, and essentially making a custom control, is flexible and should be able to do this among other things.

Thanks :)

I tried to use ListBox with my own DrawItem..

But with list view it looks much better, and the checkboxes are themed!

thanks
