MemoEdit
The MemoEdit component renders a multi-line text area for Dataverse memo (multi-line text) columns.
Rows
Set Rows to control the visible height of the text area. The default is determined by the column metadata.
Length Constraints
Use MinLength and MaxLength to enforce text length constraints. MaxLength is automatically populated from the column metadata if not explicitly set.
Example
