MemoEdit
The MemoEdit component renders a multi-line text area for Dataverse memo (multi-line text) columns.
<MemoEdit ColumnName="description" />Rows
Set Rows to control the visible height of the text area. The default is determined by the column metadata.
<MemoEdit ColumnName="description" Rows="10" />Length Constraints
Use MinLength and MaxLength to enforce text length constraints. MaxLength is automatically populated from the column metadata if not explicitly set.
<MemoEdit ColumnName="description" MinLength="10" MaxLength="2000" />MemoEdit
Here is an example that demonstrates the use of a MemoEdit component.
