maxColumnWidth

maxColumnWidth?: number;
minColumnWidth?: number;

If maxColumnWidth is set with a value greater than 50, then columns will have a maximum size of that many pixels. If the value is less than 50, it will be increased to 50. If it isn't set, the default value will be 500.

---

maxColumnAutoWidth

maxColumnAutoWidth?: number;

Sets the maximum width that a column can be auto-sized to. Defaults to maxColumnWidth.

---

onCellClicked

onCellClicked?: (cell: Item) => void;

onCellClicked is called whenever the user clicks a cell in the grid.

---

onCellActivated

onCellActivated?: (cell: Item) => void;

onCellActivated is called whenever the user double clicks, taps Enter, or taps Space on a cell in the grid.

---

onCellContextMenu

---

onColumnMoved

onColumnMoved?: (startIndex: number, endIndex: number) => void;

onColumnMoved is called when the user finishes moving a column. startIndex is the index of the column that was moved, and endIndex is the index at which it should end up. Note that you have to effect the move of the column, and pass the reordered columns back in the columns property.

---

onColumnResize

onColumnResize?: (column: GridColumn, newSize: number, columnIndex: number) => void;
onColumnResizeEnd?: (column: GridColumn, newSize: number, columnIndex: number) => void;

onColumnResize is called when the user is resizing a column. newSize is the new size of the column. Note that you have change the size of the column in the GridColumn and pass it back to the grid in the columns property. onColumnReizeEnd is called with the same arguments, but only once the user ceases interaction with the resize handle.

onColumnResizeStart

onColumnResizeStart?: (column: GridColumn, newSize: number, columnIndex: number) => void;

onColumnResizeStart is called when the user starts resizing a column. newSize is the new size of the column.

onColumnResizeEnd

onColumnResizeEnd?: (column: GridColumn, newSize: number, columnIndex: number) => void;

onColumnResize is called when the user ends resizing a column. newSize is the new size of the column.

---

onGroupHeaderClicked

onGroupHeaderClicked?: (colIndex: number, event: GroupHeaderClickedEventArgs) => void;

Emitted whenever a group header is clicked.

---

onGroupHeaderContextMenu

onGroupHeaderContextMenu?: (colIndex: number, event: GroupHeaderClickedEventArgs) => void

Emitted whenever a group header's context menu should be presented, usually right click.

---

onHeaderClicked

onHeaderClicked?: (colIndex: number, event: HeaderClickedEventArgs) => void;

Emitted whenever a header is clicked.

---

onHeaderContextMenu

onHeaderContextMenu?: (colIndex: number, event: HeaderClickedEventArgs) => void;

Emitted whenever a column header's context menu should be presented, usually right click.

---

onHeaderMenuClick

onHeaderMenuClick?: (col: number, screenPosition: Rectangle) => void;

onHeaderMenuClick is called when the user clicks the menu button on a column header. col is the column index, and screenPosition is the bounds of the column header. You are responsible for drawing and handling the menu.

---

onItemHovered

onItemHovered?: (args: GridMouseEventArgs) => void;

onItemHovered is called when the user hovers over a cell, a header, or outside the grid.

---

onMouseMove

onMouseMove?: (args: GridMouseEventArgs) => void;

Emitted any time the mouse moves. Most behaviors relying on this should be debounced for performance reasons.

---

onRowMoved

onRowMoved?: (startIndex: number, endIndex: number) => void;

Called whenever a row re-order operation is completed. Setting the callback enables re-ordering by dragging the first column of a row.

---

preventDiagonalScrolling

preventDiagonalScrolling?: booling;

Set to true to prevent any diagonal scrolling.

---

rowSelectionMode

rowSelectionMode?: "auto" | "multi";

rowSelectionMode changes how selecting a row marker behaves. In auto mode it adapts to touch or mouse environments automatically, in multi-mode it always acts as if the multi key (Ctrl) is pressed.

---

validateCell

readonly validateCell?: (cell: Item, newValue: EditableGridCell) => boolean | EditableGridCell;

When returns false indicates to the user the value will not be accepted. When returns a new GridCell the value is coerced to match.
