Smart Rendering

Smart rendering optimizes report rendering. Enabling smart rendering updates the dependent properties as follows:

  • AutoGrowText will be set to false
  • PageCreation will be set to OnDemand
  • VirtualEvaluation will be set to true
  • EnableFetchLimit will be set to true and FetchLimitCount becomes visible and setting it to 1000.

If you modify any of the above values, the SmartRendering property will be set to false. Disabling smart rendering will revert the dependent items to their default states.

Auto Grow Text

The AutoGrowText property adjusts the text box height dynamically based on the content. When AutoGrowText set to true, the viewer may take additional time to calculate the height of each text box, depending on the data. You can enable or disable AutoGrowText for a report in the designer. By default, AutoGrowText is set to true. Configure AutoGrowText as shown below and click Update.

Virtual Evaluation

VirtualEvaluation reuses tablix cell objects to optimize memory usage. To enable it for a specific report, turn on the VirtualEvaluation property in the designer. By default, VirtualEvaluation is set to false. Configure VirtualEvaluation as shown below and click Update.
