# ValidatePanel

int ValidatePanel (int panelHandle, int *valid);

## Purpose

Verifies that the value of each numeric control in notify mode is within the range specified in the User Interface Editor or set by SetCtrlAttribute using ATTR_MAX_VALUE and ATTR_MIN_VALUE.

If a control is out of range, a red outline appears around it prompting the user to enter a new value. When the control has the input focus, a pop-up dialog box appears indicating the range and default value of the control.

| Note LabWindows/CVI calls ValidatePanel when it is preparing to generate a commit event in response to user input on a control that is in Validate mode. LabWindows/CVI generates the commit event only if all controls are in range.
