Row adding and copying

TreeGrid documentation

Only variable rows can be added or copied.
Fixed (Head and Foot) and Space rows cannot be added or copied.

Ways of adding rows to grid

Adding new empty row
New empty row can be added by actions AddRow, AddChild and other Add... actions. These actions are usually attached to Toolbar Add and AddChild Button and also to CopyMenu menu.
By API can be new row added by AddRow method.
All the settings are described below in Adding new empty rows paragraph.
Copying existing row
Existing row can be copied by actions CopyRow, CopyTree, CopySelected and other Copy...action. These actions are usually accessible from CopyMenu menu.
It is possible to copy row only, copy row with children, copy row with children, but without values, copy selected rows - with or without children.
By API can be existing rows copies by CopyRows method.
All the settings are described below in Copying existing rows paragraph.
Copying existing row by dragging
Existing rows can be copied when dragging by actions DragCopy, DragSelectedCopy, DragCopyChildren. These actions are not attached to any event by default, because by default are rows moved by dragging.
The copying actions can be attached to OnDrag... events and replace DragRow, DragSelected and DragChildren events that move the rows.
All the settings are described in Row moving documentation.
Moving existing row from another grid by dragging
From another grid are rows move always as copy - from source grid are deleted (marked as Deleted) and added as new to the destination grid.
The dragging rows can be done by actions DragRow, DragSelected and DragChildren events. These actions are usually attached as default actions for dragging rows to OnDrag event.
By API can be rows moved from another grid by MoveRowsToGrid method.
All the settings are described in Row moving documentation.
Pasting row from clipboard
TreeGrid supports pasting new rows from clipboard. To clipboard can be rows copied from the grid, from another grid, or from another application like MS Excel.
The pasting is done by actions PasteTo... These actions are attached to CtrlV event and cannot be attached alsewhere.
All the settings are described in Copy&Paste documentation.

Adding and copying restrictions

By default every row accepts every child. Remember, only variable rows can be added or copied!
To control which row accepts which child use Def and AcceptDef attributes. The row accepts as child only rows with Def attribute listed in the row's AcceptDef array. The root rows are controlled by <Root AcceptDef/>.
The new empty row gets its Def attribute from CDef attribute of its parent. Root rows use <Root CDef/>. To restrict adding to row's children, set its CDef="". By default is CDef="R".
Dynamically you can control adding new rows by API event OnCanRowAdd.
All the settings are described in Default rows documentation.

Adding new empty rows

<Cfg> bool

Adding

[1]
If rows can be added into grid.
If set to 0, grid does not permit adding new rows, copying existing rows and pasting rows from clipboard, but it is still permitted moving rows from another grid.
If set to 0, it hides Toolbar buttons Add and AddChild. If set to 0 all Add... actions fail, but AddRow method still works.
new 6.4 <Cfg> string

AddFocusCol

When set, automatically focuses this column after the row is added.
If not set, the originally focused column is used.
<I> bool

Added

[0]   Uploaded to server, support Undo
It is set to 1 when row has been added to the grid and not yet uploaded to server.
It is set to 1 for every type of adding the row (add empty, copy, drag copy, move from other grid, paste).
Added row is colored green (by default setting in Grid.css).
After uploading changes to server or calling AcceptChanges the added row just looses its state and becomes normal row.
The place where the row is added is identified by Parent, Next and Prev attributes.
<I> string

Parent

Uploaded to server
When the row is moved or added, this is id of the new parent row or position of page (from 0).
<I> string

Next

Uploaded to server
When the row is moved or added, this is id of the row below or "" if the row is the last row in its parent.
<I> string

Prev

Uploaded to server
When the row is moved or added, this is id of the row above or "" if the row is the first row in its parent.
<I> <Root> int

AddParent

[0]
If set, adds new row's children as its siblings rather than its children.
If is set to 1 adds new row before the row.
If is set to 2 adds new row as last child of the parent row.
For example, if you set AddParent of all rows and <Root> to 2, every new row will be added to the end of table, to the root.

Called before the row is added to find out if it can be added to this position.
It is called when adding new rows, copying existing rows and pasting rows. It is not called when moving rows from another grid.
parent is parent row in tree or page for root row, to its children the new row will be added.
next is next row, above it the new row will be added or null if the row will be added as the last child or last row on page.
Return false to restrict row adding. Since 12.0 returning null permits row adding.
API event void

OnRowAdd

(TGrid grid, TRow row)
Called after the row is added, but before it is displayed. Usually to change default values. Called from AddRow.
new 7.0 API event void

OnRowAdded

AddRow

(TRow parent, TRow next, int show = 0, string id = null, string Def = null)
Adds new empty row to grid and returns it.

If set focus, focuses the newly added rows, preserves the focused columns.
If set test = 1, does not add the rows, just test if it is possible and returns true or null.
Uses AddRow and also calls OnCanRowAdd and OnRowAdded API events and alerts error if the row cannot be added to given position.
