  • I666355, FB64089 - Added support for wrapping checkbox content in the filter and column chooser dialog by enabling the AllowTextWrap property as true in FilterSettings and ColumnChooserSettings.

  • Significantly improved performance when exporting PDF documents with Foreign Key Columns in the Grid..

Breaking Changes

  • Achieved UI responsiveness during the PDF export process, allowing seamless user interaction. The PDF export icon in the toolbar is disabled during export and re-enabled upon completion.

  • The behavior of the Refresh method in the Grid component has been updated to enhance clarity and provide better control over dynamic property changes.

    Previous Behavior:

    • The Grid.Refresh() method was used to refresh the grid header and content when dynamic property changes were applied. It automatically updated columns, aggregates, or other properties without additional parameters.

    Code Example:

      <button @onclick="Refresh">Refresh</button>
  <SfGrid @ref="Grid" DataSource="@Orders">
      @if (renderColumns)
      {
          <GridColumns> <!-- Define grid columns (5 columns) here --> </GridColumns>
          <GridAggregates> <!-- Define aggregates here --> </GridAggregates>
      }
      else
      {
          <GridColumns> <!-- Define grid columns (3 columns) here --> </GridColumns>
      }
  </SfGrid>
  @code
  {
      private SfGrid<Order> Grid;
      private bool renderColumns = false;
      private async Task Refresh()
      {
          renderColumns = true;
          await Grid.Refresh(); // Refresh the grid
      }
  }

    Current Behavior:

    • The Grid.Refresh() method now supports an optional parameter, isModelRefresh. By passing true (e.g., Grid.Refresh(true)), the grid explicitly re-renders to reflect updates in model properties.

    Code Example:

      <button @onclick="Refresh">Refresh</button>
  <SfGrid @ref="Grid" DataSource="@Orders">
      @if (renderColumns)
      {
          <GridColumns><!-- Define grid columns (5 columns) here --> </GridColumns>
          <GridAggregates><!-- Define aggregates here --></GridAggregates>
      }
      else
      {
          <GridColumns> <!-- Define grid columns (3 columns) here --> </GridColumns>
      }
  </SfGrid>
  @code
  {
      private SfGrid<Order> Grid;
      private bool renderColumns = false;
      private async Task Refresh()
      {
          renderColumns = true;
          await Grid.Refresh(true); // Ensure the grid rerenders with dynamic property updates
      }
  }
