Conditional Header Row Icon + Tooltip for Grid Column-Level Messaging

Please consider adding support for an optional header row indicator that can display a conditional icon + themed tooltip, used to show non-field-level validation or status messages — especially during inline or in-cell editing, and ideally in batch edit scenarios.

Why This Is Needed

In enterprise applications — especially those with batch entry workflows, cutover planning, or financial approvals — validation needs often extend beyond just field-level errors. Common use cases include:

  • Rule-level messages (e.g., “Only one Primary Owner allowed per group”).
  • Cross-row or cross-field issues (e.g., overlapping dates, missing dependencies).
  • Batch edit feedback (e.g., conflict indicators before submit).

Currently, there’s no clean way to show column-specific validation or guidance in a visual, inline way that:

  • Doesn’t clutter the cell.
  • Surfaces at the column level (just like a header).
  • Feels native to the grid.

Hi Ken,

Showing validation in the column header sounds a bit uncommon in terms of UX. Can you show us an existing web Grid component with such a built-in feature?

In addition:

  • The Grid has no suitable place in the header row to render UI that is not related to any specific column.
  • There is no guarantee that the Grid header row will be visible in the viewport, or that the user will notice the validation notification there. Consider a popup Dialog instead, or validation UI, which appears near the currently focused component.
  • "non-field-level validation or status messages" are an excellent candidate for popup editing a ValidationSummary.
  • The described scenario implies custom validation rules.

In other words, we are discussing a potential built-in feature, which has a few prerequisites that are outside the Grid's control. That's why, if you want to achieve the described UI and UX as is, my suggestion is to rely on the existing Grid header or toolbar templates.
