ListView / working with columns..

Question

Ok, I know how to modify the properties of a listView control such that the columns show up and I am familiar with how to add items to the list view. The problem I am having is that I can't figure out how to add multiple line items to a single row of a listView so that the data lines up with the appropriate column. Can someone please give me a hint on how to do this? Thank you, Bob

Answer 1

listView.Items.Add(fileName) will add the parent item in the list view. Then you'd issue, listView.SubItems.Add(subItem) to add subitems under the parent item in ONE row. Imagine how the Windows Explorer displays files. First Filename, Data, Size, etc etc. That's what it does. So, retrieve the data from using data reader and insert it right in the list view; listView.Items.Add(dataReaderReadItem); listView.SubItems.Add(dataReaderReadItemFromtheNextColumnInTheRow); If you need to do casting before adding..take care of that .

Unfortunately it didn't.. :( What does the following line actually add in to the list view??? anything? listview.Items.Add(fileName); I am sort of new to all this so please forgive me.. I have a database which I can successfully connect to. I am trying to use the data reader to read records from a table and then populate this information in to the list view. I guess I don't understand how I can get the information from the DB... reader.GetInt32(0).tostring(), **as information for column 1 ** reader.GetString(1).tostring(), ** as information for column 2 **... etc.. Thanks, Bob

You'll have to add the columns first, which you know how. Then add subitems under the columns: Follow this: listview.Items.Add(fileName); //fileName is your parent Column listview.Items[count].SubItems.Add(size); //size is the child under the Parent Column listview.Items[count].SubItems.Add(date); //another child. so this will look like in ListView with 3 columns. First row is the column. File Name Size Date fileName1 size1 date1 fileName2 size2 date2 Hope that helps. JJ
