I have a ListBox that initially displays with the first item selected. I want it to display with no items selected. Is this possible?

If an item gets selected, it is added to the SelectedItems collection. So, if you want to deselect an item you call RemoveAt on the SelectedItems collection instead of the Items collection.
Clear ListBox With the DataSource = null Approach in C#DataSource property equal to null to remove the data source and then use the ListBox. Items. Clear() function to clear the previous items in the list box. The following code example shows us how we can empty a list box with the ListBox.
Choose Multiple Items from ListboxOn the worksheet, click on a cell that has a drop down list. The VBA listbox pops up automatically, and shows all the choices from the cell's drop down list. Add a check mark to one or more of the items in the list box. When you're finished selecting items, click the OK button.
To edit an item in a listbox, all you need is a simple editbox that overlays on a listbox item. The idea is to create a TextBox control and keep it hidden and show it whenever required. Two events are added to the EditBox. KeyPress event to check if the enter key is pressed when the user has finished editing the item.
ListBox.ClearSelected() or
ListBox.SelectedIndex = -1 Of course, they are member methods.
