If lstStock.Items(x3) = LastStockCode1 Then
lstStock.Items(x3).attributes.add("style", "color:red")
Exit For
End If
Next x3

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!

Change Color Of One ListBox Item

Mar 9, 2011

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.

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.

Get Listbox Text Using Index Of Its Item?

Aug 19, 2010

In simple terms, I want to compare the value of a databound listbox display member with another string. However; I need to convert the listbox databound items to an array first as I may have to do 1,000's of comparisons on this.

I have a databound listbox from a sql server table that populates fine. I'm trying to retrieve the display value of a listbox item without selecting the item. My goal is to compare items in listbox1 with items in listbox2 and if item is in listbox1 matches an item I want to load into Listbox2, then I do not add the item to Listbox2. Listbox 2 is not databound but contents I'm loading come from a datatable.

So, I iterate through the items in listbox2's datatable but as I'm adding the items from the datatable to the listbox2, I check if the item exists in listbox1. The data that is being compared is the Displaymember of Listbox1 and a string value I want to manually load into listbox2.[code]....

I'm trying to open a specific file when a listbox item is selected and I have that down but I'm running into the problem of needing to have "" in the display which is impossible from what I can tell in the code. I just need to know what goes in the quotes which will open the file. Also lets say the text file was 'supportdoc1.rtf' and was located in a folder inside of the program folder called 'SupportDocuments' would the path be "SupportDocumentssupportdoc1.rtf" [Code]

Set ListBox Item Text Without Knowing What Kind Of Object It Is

May 14, 2010

I'm creating an editable ListBox control, where the user can double-click an item to edit it. When double-clicked, I simply overlay a TextBox over the item, so the user can change the text and then commit it by pressing Enter or leaving the TextBox. The 'commit' is simply this:[code]where 'editingIndex' is the index of the item being edited, and 'textBox' is the TextBox object.If the ListBox contains strings, this works just fine. The item being edited is replaced by the textbox Text string.However, if the ListBox contains some other object (let's say a custom class), this is a problem! It still "works", in that it still sets the text of the item, but the item is no longer an instance of that custom class! It is now a String, and all other information about the item is lost. So, I really want to let the user be able to change the text representation of ANY object, without replacing the object with a string. Obviously, I cannot know how the object displays its text (well, by the ToString function of course, but I cannot know what the ToString function returns).Now, I am having a few ideas how to approach this, but none really work the way I want. I am pretty sure that I'm going to have to provide some kind of event that the user has to handle. I'm thinking something like this:

- When the item edit is committed, an event is raised
- This event contains the Item being edited (as an object, the user has to cast it himself), and the new text of the item.-
- The user handles this event, and assigns the new text to the correct property.

For the Person class, this could look something like this.My ListBox should raise this event, and assign the new item like this.[code]I think this should work (although I haven't tested it), but there's one problem with this approach:When the items are just strings, the user still needs to implement this event handler, while he shouldn't have to (I can simply assign the new text string to the item). So, if the user is simply using strings, he still needs to do this for every instance of my listbox:[code]So what I'm really looking for is a way so that I can implement the default behavior (for String items), and still allow the user to override this behavior if he is not using strings.I may be overlookihe obvious solution here, but I can't figure it out... Overriding is done when you inherit a class, but the user isn't going to inherit my custom listbox (well he CAN, but he shouldn't have to). He is just going to handle the event. And if he doesn't handle the event, my listbox uses the default implementation.
