Newbie: Porblem with ListView...
-
Hello all, I am having a little trouble with a ListView. I am trying to update an item but it isn't doing what it should... To explain: I have a list containing about 20 items. I can find the index location for the item I want to update. I am then removing the old item at the found index location, and then inserting the new item at the same point. It works, but with one problem... It isn't inserting the new item at the correct index position. Instead it is putting it at the bottom of the list... And I can't work out why?? I am viewing the list in 'tile' view. Can anybody help? Thanks in advance, Phil

Hello, You tried already : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformslistviewlistviewitemcollectionclassinserttopic.asp Creates a new item and inserts it into the collection at the specified index. [C#] public ListViewItem Insert(int, string); that doesn't work? You have some code ?

Thanks for the reply... I can insert the item. It is just not being inserted where I asked it to be... Here is the code:
// Find location of original item in listview ListViewItem temp = new ListViewItem(); temp = listView_main.FindItemWithText(item_text, true, 0); int location = temp.Index; // Create listview item ListViewItem lvItem = new ListViewItem(item_text, icon); lvItem.SubItems.Add("Name:" + name + "(" + aka + ")"); lvItem.SubItems.Add("Data:" + data); lvItem.ToolTipText = item.ToString(); lvItem.Group = listView_main.Groups[0]; // Remove old item in listview listView_main.Items.RemoveAt(location); // Add new item to listview listView_main.Items.Insert(location, lvItem);Hope that helps...
