To set the values of

Use

A ListView control item

Syntax 1 For ListView controls

A ListView control item and column

Syntax 2 For ListView controls

A TreeView control item

Syntax 3 For TreeView controls


Syntax 1 For ListView controls

Description

Sets data associated with a ListView item to the property values you specify in a ListViewItem variable.

Applies to

ListView controls

Syntax

listviewname.SetItem ( index, { column }, item )

Argument

Description

listviewname

The ListView for which you are setting item properties

index

The index number of the item for which you are setting properties

column

The index number of the column of the item for which you want to set properties

item

The ListViewItem variable containing property values you want to assign to a ListView item

Returns

Integer. Returns 1 if it succeeds and -1 if an error occurs.

Usage

You can set properties for any ListView item with this syntax. If you do not specify a column, SetItem sets properties for the first column of an item. Only report views display multiple columns.

To add items to a ListView control, use the AddItem function. To add columns to a ListView control, use AddColumn. To set display values for the columns of a ListView item, use Syntax 2.

If you want to set column properties, such as alignment or width, use SetColumn. These column properties are independent of the ListViewItem objects.

To change pictures and other property values associated with a ListView item, use GetItem, change the property values, and use SetItem to apply the changes back to the ListView.

Examples

Example 1

This example uses SetItem to change the state picture index for the selected lv_list ListView item:

listviewitem lvi_1


lv_list.GetItem(lv_list.SelectedIndex( ), lvi_1)

lvi_1.StatePictureIndex = 2

lv_list.SetItem(lv_list.SelectedIndex () , lvi_1)

Syntax 2 For ListView controls

Description

Sets the value displayed for a particular column of a ListView item.

Applies to

ListView control

Syntax

listviewname.SetItem ( index, column, label )

Argument

Description

listviewname

The ListView control for which you are setting a display value

index

The index number of the item for which you are setting a display value

column

The index number of the column for which you want to set a display value

label

The string value or variable which you are assigning to the specified column of the specified ListView item

Returns

Integer. Returns 1 if it succeeds and -1 if an error occurs.

Usage

You must include the column number as an argument, even if you are only assigning values to a single-column ListView control. To specify the properties for a ListView item, use Syntax 1.

Examples

Example 2

This example assigns display values to three columns in a report view for three lv_list ListView items:

listviewitem l_lvi

integer li_count, li_index


FOR li_index = 1 to 3

		li_count=li_count+1

		lv_1ist.AddItem("Category " + String(li_index), 1)

NEXT


lv_list.AddColumn("Composition", Left! , 860)

lv_list.AddColumn(" Album", Left! , 610)

lv_list.AddColumn(" Artist", Left! , 710)


lv_list.SetItem(1 , 1 , "St. Thomas")

lv_list.SetItem(1 , 2 , "The Bridge")

lv_list.SetItem(1 , 3 , "Sonny Rollins")


lv_list.SetItem(2 , 1 , "So What")

lv_list.SetItem(2 , 2 , "Kind of Blue")

lv_list.SetItem(2 , 3 , "Miles Davis")


lv_list.SetItem(3 , 1 , "Goodbye, Porkpie Hat")

lv_list.SetItem(3 , 2 , "Mingus-Ah-Um")

Sets the data associated with a specified item.

treeviewname.SetItem ( itemhandle, item )

Argument

Description

treeviewname

The name of the TreeView control in which you want to set the data for a specific item

itemhandle

The handle associated with the item you want to change

item

The TreeView item you want to change

Returns

Integer. Returns 1 if it succeeds and -1 if an error occurs.

Usage

Typically, you would call GetItem first, edit the data, and then call SetItem to reflect your changes in the TreeView control.

Examples

Example 3

This example uses the ItemExpanding event to change the picture index and selected picture index of the current TreeView item:

treeviewitem l_tvi

long ll_tvi


ll_tvi = tv_list.FindItem(CurrentTreeItem! , 0)

tv_list.GetItem(ll_tvi , l_tvi)

l_tvi.PictureIndex = 5

l_tvi.SelectedPictureIndex = 5


tv_list.SetItem( ll_tvi, l_tvi )
