Inserts an item as the last child of a parent item.
Description
Inserts an item as the last child of its parent.
Applies to
TreeView controls
Syntax
treeviewname.InsertItemLast ( handleparent, label, pictureindex )
|
Argument |
Description |
|---|---|
|
treeviewname |
The TreeView control in which you want to specify an item as the last child of its parent. |
|
handleparent |
The handle of the item that will be the inserted item's parent. To insert the item at the first level, specify 0. |
|
label |
The label of the item you want to specify as the last child of its parent. |
|
pictureindex |
The picture index for the item you want to specify as the last child of its parent. |
Return value
Long.
Returns the handle of the item inserted if it succeeds and -1 if an error occurs.
Usage
If more than the item label and Index need to be specified, use syntax 2.
If SortType is anything except Unsorted!, items are sorted after they are added and the TreeView is always in a sorted state. Therefore, calling InsertItemFirst, InsertItemLast, and InsertItemSort produces the same result.
Examples
This example populates the first three levels of a TreeView using InsertItemLast:
long ll_lev1, ll_lev2, ll_lev3, ll_lev4
int index
tv_list.PictureHeight = 32
tv_list.PictureWidth = 32
ll_lev1 = tv_list.InsertItemLast(0,"Composers",1)
ll_lev2 = tv_list.InsertItemLast(ll_lev1, &
"Beethoven",2)
ll_lev3 = tv_list.InsertItemLast(ll_lev2, &
"Symphonies",3)
FOR index = 1 to 9
ll_lev4 = tv_list.InsertItemSort(ll_lev3, &
"Symphony # " String(index), 4)
NEXT
tv_list.ExpandItem(ll_lev3)
tv_list.ExpandItem(ll_lev4)See also

Syntax
treeviewname.InsertItemLast ( handleparent, item )
|
Argument |
Description |

The TreeView control in which you want to specify an item as the last child of its parent. |
|
handleparent |
The handle of the item that will be the inserted item's parent. To insert the item at the first level, specify 0. |
|
item |
A TreeViewItem structure for the item you are inserting. |
Return value
Long.
Returns the handle of the item inserted if it succeeds and -1 if an error occurs.
Usage
If SortType is anything except Unsorted!, items are sorted after they are added and the TreeView is always in a sorted state. Therefore, calling InsertItemFirst, InsertItemLast, and InsertItemSort produces the same result.
Examples
This example inserts the current item as the last item beneath the root item in a TreeView control:
long ll_handle, ll_roothandle treeviewitem l_tvi ll_handle = tv_list.FindItem(CurrentTreeItem!, 0) ll_roothandle = tv_list.FindItem(RootTreeItem!, 0) tv_list.GetItem(ll_handle , l_tvi) tv_list.InsertItemLast(ll_roothandle, l_tvi)

|---|---|
|
controlname |
The RibbonMenu control into which you want to insert a menu item as the last item. |
|
ParentIndex |
The index of the menu item (RibbonMenuItem) into which you want to insert a submenu item. It cannot be an index of a separator (that is RibbonMenuItem with ItemType 1). If not specified, a menu item will be inserted as the last item; if specified to a valid value, a submenu item will be inserted as the last item under the menu item (whose index is ParentIndex); if specified to an invalid value, an error would occur and this operation would return -1. |
|
Text |
The text that displays in the menu item or submenu item. |
|
PictureName |
The name of the file that contains the picture. The image will be displayed in 16*16 pixels. |
|
Clicked |
The name of the Clicked user event to be bound with the menu item. The Clicked user event for the menu item must be defined with the required parameters and types. For details, see Clicked. |
|
Item |
A RibbonMenuItem item you want to insert. Only RibbonMenuItem with "Normal(0)" or "Separator(1)" ItemType is supported. If RibbonMenuItem is with other ItemType such as "Recent(2)", an error would occur and this operation would return -1. |
Return value
Long.
Returns the position of the item if it succeeds and -1 if an error occurs. If any argument's value is null, returns null.
Usage
Only menu items with the "Normal" or "Separator" type (that is RibbonMenuItem with ItemType 0 or 1) can be added to the RibbonMenu control.
A RibbonMenu control can contain menu items in no more than two levels.
The user events to be bound with the menu item must be defined correctly according to the requirements of RibbonMenuItem. For details, see Clicked and Selected.
Example 1
This example inserts a "MenuItem1" menu item as the last item and then inserts two submenu items under "MenuItem1" in the following display order: "SubMenuItem1", "SubMenuItem2".
Long ll_Return,ll_Index
RibbonMenu lr_Menu
ll_Index = lr_Menu.InsertItemLast ("MenuItem1", "AddSmall!", "Ue_MenuItem1Clicked")
ll_Return = lr_Menu.InsertItemLast (ll_Index, "SubMenuItem1", "AddSmall!", "Ue_MenuItem11Clicked")
ll_Return = lr_Menu.InsertItemLast (ll_Index, "SubMenuItem2", "AddSmall!", "Ue_MenuItem12Clicked")
Example 2
This example also inserts a "MenuItem1" menu item as the last item and then inserts two submenu items under "MenuItem1" in the following display order: "SubMenuItem1", "SubMenuItem2". It first defines three RibbonMenu items (lr_MenuItem1, lr_SubMenuItem1, lr_SubMenuItem2) with various properties (including binding with the "Ue_MenuItem1Clicked" and "Ue_MenuItem1Selected" user events), and then inserts lr_MenuItem1 as the last menu item "MenuItem1", and inserts the other two as the submenu items under "MenuItem1" in the following display order: "SubMenuItem1", "SubMenuItem2".
Long ll_Return, ll_Index RibbonMenu lr_Menu RibbonMenuItem lr_MenuItem1, lr_SubMenuItem1, lr_SubMenuItem2 lr_MenuItem1.Text = "MenuItem1" lr_MenuItem1.PictureName = "AddSmall!" lr_MenuItem1.Clicked = "Ue_MenuItem1Clicked" lr_MenuItem1.Selected = "Ue_MenuItem1Selected" lr_SubMenuItem1.Text = "SubMenuItem1" lr_SubMenuItem2.Text = "SubMenuItem2" ll_Index = lr_Menu.InsertItemLast (lr_MenuItem1) ll_Return = lr_Menu.InsertItemLast (ll_Index, lr_SubMenuItem1) ll_Return = lr_Menu.InsertItemLast (ll_Index, lr_SubMenuItem2)
