Change Background Color Of Item In Listbox / When Its String Value Is Equal To Something?
Oct 14, 2011
i have a listbox that contains the words "week1", "week2",all the way up to "week52" and when i select a week from the listbox it will retrieve a value from a mysql database that will represent a progress bar value. my progress bar has a range of 0-120 and i would like to have all the weeks that have values higher than 100 to be highlighted or marked somehow, in the listbox. so my question is, "is there a way to set the background color of certain weeks in the listbox to orange based on the value that they represent on the database?
for example for "week1", the value is 114, so when the listbox loads, i want the background color of the item "week1" in the list to be orange (indicating that it's current value is higher than 100)? i know that this requires me to implement a user defined drawing function for the listbox items but i dont know where i would even start. i would like this to be somewhat automatic so that it checks the values and changes the background colors of any value higher than 100, instead of me specifying a name of the item.
I am using .NET 1.1, so I don't have the access to listitem object. I would like to change the text color or the background color of certain items in a listbox. can it do it in .NET 1.1?
I'm kind of stuck on this one, and i know it's going to be something simple, but I just can't come up with the solution. I want to be able to assign a background color for each item in a listview with a predefined string or other variable type, so when item's are added to the listview and they contain a specific string, the background color for that item will be changed to the predefined color which is stored in a string (or other variable). When I attempt to change the background color of the listview item using a string ie. "Blue" I get an error.[code]....
The code below is from your forum and it gives the error: missingmemberexception?

One solution was two pages of code! This s/b simple. I have the INDEX of the list item. I just want to change the words in that item from the color at list build time to red to highlite it!
I'm making a small program in VB.NET. I have a listBox and a button. I'd like to be able to press the button and have the selected listBox item change it's foreColor to green. I've tried many ways of doing this, ranging from overriding the draw method to using a listView (listBox is much better for what I'm doing, please don't recommend that I use a listView, I've already tried it.)At first I thought this would be simple, but it's the exact opposite and I'm very frustrated that such a simple task should be so difficult. I don't want to use any third-party controls, as I'd have to completely re-write my application.

I want to change the Forecolor and the Font color of the DateTimePicker. (The one Narrow white window with Black font which appears on dragging "D.T.Picker" control onto the "Form").
So far, I couldn't do it.
I found the same question (by someone on 31st Aug 2007) and answers by Figo Fei in the forum. Figo fei said, "It is truly not possible to directly modify the forecolor of the DateTimePicker which is concealed in its implementation. However, there is a workaround to change its forecolor through own-draw mode in a custom control inherited from dateTimePicker.". And he gave the code which looks like - for me - either VC++ or VC#.
