ShowRecordPreviewRow

[Administrator]

Is there anyway to not show this for rows that have no data to be displayed in the preview?

I am filling this in the QueryCellStyleInfo event and would like to not show it for rows that don''t have any descriptions (which is what I am displaying in it).

It also show up for the nested tables. How do you only show this in the base table?

To show/hide for individual records you need a custom engine where you derive GridRecord and override this method:

public override bool ShouldShowRecordPreviewRows()

and return true/false based on your condition.

You can see an example of creating a custom engine and deriving GridRecord in this sample.

I get the following error: ''XXX.GroupingRecordRow.ShouldShowRecordPreviewRows()'': no suitable method found to override This was after adding the following class to my engine class public class GroupingRecordRow : GridRecordRow { ///

/// Initializes a new object in the specifed record part. ///

/// The parent element. public GroupingRecordRow(RecordRowsPart parent) : base(parent) { } public override bool ShouldShowRecordPreviewRows() { return true; } }

It should be GridRecord instead of GridRecordRow. Sorry.

public class GroupingEngineFactory : GridEngineFactoryBase
{
	// Add this line in your forms ctor:
	// GroupingEngineFactory provides a modified GridChildTable that adds an extra section
	// GridEngineFactory.Factory = new GroupingEngineFactory();

	public override GridEngine CreateEngine()
	{
		return new GroupingEngine();
	}
}
public class GroupingEngine : GridEngine
{
	public override Record CreateRecord(Table parentTable)
	{
		return new MyGridRecord(parentTable);
	}
}
public class MyGridRecord : GridRecord
{
	public MyGridRecord(Table parent)
		: base(parent)
	{
	}
	public override bool ShouldShowRecordPreviewRows()
	{
		//return false to hide this preview record
		//return true to show it
		return false; 
	}
}
