Edit Channels

When multiple channels are selected, you can right‑click any selected channel header to open a context menu with options for managing and repositioning the selected channels. The Edit menu option lets you modify shared properties across multiple selected channels at once, including regular channels and array channels.

Open the Edit Channels Dialog

In the database, select two or more channels (Ctrl‑ or Shift‑select).
Right‑click any selected channel header.
Choose Edit from the context menu.

The Edit Channels dialog opens. A banner at the top indicates how many channels are selected and confirms that changes apply to all selected channels.

Edit Channels dialog options

Mixed Values When the selected channels do not share the same value for an attribute: Text fields and drop‑down lists display `-different values-`. The Protected checkbox appears in an indeterminate/mixed state . Leaving a field unchanged preserves each channel’s existing value. Entering a new value applies that value to all selected channels.
Class	Describes the type or purpose of the channel (for example, survey line, elevation, interpretation code). Accepts standard text. Supports Unicode characters, including accented characters.
Units	Specifies the measurement units for channel values (for example, m, m/s, nT). Accepts standard text. Supports Unicode characters.
Protected	Controls whether channels are protected from certain operations. When editing multiple channels, the Protected checkbox supports three states: Checked – All selected channels are protected. Unchecked – All selected channels are not protected. Indeterminate – Existing protection states are preserved (some channels are protected and others are not). Leaving the checkbox in the indeterminate state preserves existing protection states. Explicitly checking or clearing it applies that state to all selected channels.
Display Settings Display settings control how channel values appear in the user interface.
Format	Controls how numeric values are displayed. Available formats include the standard options used elsewhere in the database. Displays `-different values-` if formats differ. Selecting a format applies it to all selected channels.
Field width	Specifies the display width (in characters) for channel values. Displays `-different values-` if widths differ. Entering a value applies it to all selected channels.
Decimals	Specifies the number of decimal places displayed for numeric values. Displays `-different values-` if values differ. Entering a value applies it to all selected channels.
Applying or Discarding Changes
[OK]	Click OK to apply your changes. Only modified attributes are updated. Attributes left as `-different values-` remain unchanged for each channel.
[Cancel]	Click Cancel or close the dialog to discard all changes. No channel properties are updated.

Application Notes

The Edit Channels dialog allows you to efficiently standardize metadata and display settings while preserving intentional differences between channels. The -different values- indicators and the indeterminate Protected state ensure that only the attributes you choose to change are applied across the selection.

How Multi‑Channel Editing Works

All changes apply to the selected channels.
Only the attributes you explicitly modify are updated.
Attributes you do not change remain unchanged for each channel.

Validation and Limitations

All fields are validated before changes are applied.
Invalid entries (for example, non‑numeric values for Field width or Decimals) are flagged and must be corrected.
Long text values may be truncated at internal limits without warning.
