ListView Fundamentals :: C#
-
Hi. I have some fundamental questions on the listview. 1) I added a listview with some columns, however, the column titles do not appear. The columns are there, but they do not appear. Is there a setting in winform that can hide it? 2) How do you search for an item in the listview? 3) How do you set the text of a specific item in a listview? For example, I want to set the text of item 2 column 1. Thanks, Kuphryn

You need to be on Detail mode instead of Small Icons, Large Icons, or List. kuphryn wrote: 2) How do you search for an item in the listview? Well, you would do something like this:
myListView.Items.IndexOf(myListViewItem);where myListViewItem is the ListViewItem that you want. kuphryn wrote: 3) How do you set the text of a specific item in a listview? For example, I want to set the text of item 2 column 1.myListView.Items[0].SubItems[0].Text = "This text appears in the first row under the second column!"Hope that helps. :)

Nice!!! Thanks. One last question on this item. How do you determine exactly what item the user selects via mouse? For example, let say I click on item 2, I want the program to do something with item 2. Kuphryn
Then you would use the
myListView.SelectedItemsormyListView.SelectedIndicesproperty instead ofmyListView.ItemsBy the way, there are some really cool replacements for the standard list view. Consider this one for your app instead. Carlos really does a good job on custom controls. He also explains what's wrong with the standard one and why he implemented the new features that he did. http://www.codeproject.com/cs/miscctrl/sortedlistview.asp[^]

Okay. Thanks. I tried using SelectedItems, but it does not return the correct selected item. For example, it always return index 0 even if I select index 10. Kuphryn
Are you handling the SelectedIndexChanged event? And, since SelectedItems is a collection, did you access it like this:
myListView.SelectedItems[0]

Yes. I added a handler for SelectedIndexChanged event and checked SelectedItems[...]. However, for some reason item 0 is always selected even if I click on item 2002. Weird! Kuphryn
Actually, I just played around with it a bit, and you should handle the click event instead. Then do
myListView.SelectedItems[0]. Oh, and you have to use 0 because that's the only item in the collection of selected items.

It is not an application. It is something I have to do for a school project. Thus, I do not consider it an application. Lets just say it is a "Hello World" instruction using C#. Thanks again, Kuphryn
Cool. Where do you go to school?

I go to school in, lets just say, a school to a pretty bad Computer Science program. Oh, I guess you already see that via the fact that we even consider C#. Kuphryn
