Add an item

To add items to the MultiSelect control, use Add method of C1CheckListItemCollection as shown in the following code. For example, the following code adds “Edward” in dropdown list of the MultiSelect control:

C1MultiSelect1.Items.Add("Edward")

c1MultiSelect1.Items.Add("Edward");

MultiSelect also allows you to add an item at a specific position using Insert method of C1CheckListItemCollection and specify an index value for the new item in it. For example, the following code inserts a name, Robert, to the fifth position, adjusting the position of the other items in the dropdown list:

C1MultiSelect1.Items.Insert(4, "Robert")

c1MultiSelect1.Items.Insert(4, "Robert");

Remove an item

MultiSelect lets you delete an item from the list using RemoveAt method of C1CheckListItemCollection as shown in the following code. The method takes one argument, index, which specifies the item to remove. For example, the following code deletes sixth entry from the list.

C1MultiSelect1.Items.RemoveAt(5)

c1MultiSelect1.Items.RemoveAt(5);

MultiSelect also allows you to delete a selected item from the MultiSelect control using Remove method as shown in the following code:

C1MultiSelect1.Items.Remove(C1MultiSelect1.SelectedItem)

c1MultiSelect1.Items.Remove(c1MultiSelect1.SelectedItem);

To remove all the entries from the list, use Clear method of C1CheckListItemCollection as shown in the following code:

C1MultiSelect1.Items.Clear()

c1MultiSelect1.Items.Clear();

To access a specific item from the MultiSelect control dropdown list, use Items property of C1MultiSelect class and specify the index of that item. Furthermore, you can change the value of an item in the list using Value property of the C1CheckListItem class. For example, to access and change the value of third item from the list, write the following line of code:

C1MultiSelect1.Items[2].Value = "Jake"

c1MultiSelect1.Items[2].Value = "Jake";
