AI Search Gap: RadGridView Manual Column Fill with Grouped Columns

[dessyordanova]

Decision

Recommend — Create a new knowledge-base article that demonstrates how to calculate and adjust the last visible column's width when grouping is applied, including support for group indents and visible-column filtering when AutoSizeColumnsMode = None.

Confidence: High
Gap: Missing documentation

Why

Customer need: A formula to calculate and adjust the last visible column's width that subtracts the space occupied by multiple group-by columns/indents when AutoSizeColumnsMode = None.

Current gap: The existing KB article mixing-bestfit-and-fill-mode-in-gridview.md focuses on the general best-fit and fill-mode scenario for flat grids. It does not address grouped grids, visible-column filtering during width calculations, or accounting for radGridView1.TableElement.GroupIndent for each group descriptor. As a result, Agentic RAG cannot adequately answer follow-up questions related to grouping.

Preferred approach: Publish a dedicated KB article that specifically covers grouped GridView scenarios, including the required width-calculation formula, group-indent handling, and updated code examples. This provides a focused reference for grouping-related implementations without altering the original article's scope.

Benefits: A separate article improves discoverability for grouping scenarios, enables more precise retrieval by Agentic RAG, and allows the grouped-grid implementation details to be documented comprehensively.

Outcome: The new KB article fills the documentation gap for grouped GridView layouts while complementing the existing mixing-bestfit-and-fill-mode-in-gridview.md article.

🟡 Changes recommended

The new KB article contains a few style-guide/clarity issues in front matter and a concrete bug in the sample code that can produce a negative column width.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adds a dedicated knowledge-base article documenting how to calculate and adjust the last visible RadGridView column width in grouped scenarios when AutoSizeColumnsMode = None, and links to it from the existing “mixing best-fit and fill mode” KB.

Changes:

• Adds a new KB article covering grouped RadGridView fill-width logic (including group indent and visible-column filtering).
• Updates the existing KB’s See Also section to cross-link to the new grouped-grid article.
