Button in command bar doesn't appear after grid item selection

  • Article

This article provides a solution to the issue where a custom button on the command bar doesn't appear after selecting one or more grid items in Dynamics 365 apps.

Applies to:   Microsoft Dynamics 365 Original KB number:   4481268

Symptoms

A custom button is configured to appear in the grid, either in the HomePageGrid or SubGrid in Dynamics 365 apps.

  • In the web client, this button appears in the ribbon or command bar regardless of whether grid items are selected.
  • In the Unified Client Interface (UCI), this button appears when no grid items are selected. However, after selecting one or more grid items, the button disappears.

Cause

This behavior is by design in the UCI. UCI introduces a context-sensitive approach to button visibility in grids. Specifically:

  • Buttons are categorized as either item-specific or not.
  • When one or more grid items are selected, only item-specific buttons are displayed.
  • Buttons that don't require item selection are hidden when grid items are selected.

The context-sensitive behavior determines whether a button is considered item-specific based on the presence of a selection count rule in the associated command. If the command has a selection count rule, the button is categorized as item-specific.

Note

Flyouts and split buttons are excluded from this behavior and are displayed regardless of item selection. This ensures that dynamic menu items aren't hidden incorrectly.

Resolution

This design affects all buttons, including both custom and out-of-box buttons, except for flyouts and split buttons. This change helps prioritize item-specific commands by hiding non-item-specific buttons during item selection.

In most cases, it's helpful to hide buttons that don't act on selected items, so that item-specific commands appear more prominently.

If you need to run a generic command unrelated to the items selected during item selection, you can add the following rule to the definition of the custom ribbon command:

<EnableRule Id="Mscrm.AnySelection" />

This rule causes the Unified Client to treat the command as both an item-specific and a non-item-specific command, ensuring the button appears in both scenarios.
