ZeeGrid Control Message



An application sends a ZGM_SETCELLRESTRICTION to programmatically set a cell's restriction value. Restrictions perform numeric data entry validation, allowing only valid characters per the restriction to be entered.

wParam = (WPARAM)(int) iCellIndex;   //Cell index
lParam = (LPARAM)(int) iRestriction; //Cell restriction value


The value of wParam. The index of the ZeeGrid cell.

The value of lParam. The data restriction attribute value to set the specified cell. Valid values are in the range of [0..4].
The restriction values are defined as follows:

  1. No Restriction
  2. Signed Integer
  3. Unsigned Integer
  4. Signed Double
  5. Unsigned Double

Return Values

This message does not return a value.


A restriction only restricts the characters allowed to be entered into a cell by manual keyboard input. If a paste operation is performed on restricted cells, the restriction will apply and the paste operation may not be able to be completed fully.
