TOPIC: Automatic completions of cells based upon selected criteria

Automatic completions of cells based upon selected criteria 1 year, 4 months ago #1

Evening Is it possible that when you pick a selection from a cell that other cells can be populated based upon the selection. For example, if I pick Apple, the other cells such a Fruit or Vegetable, Shape would be automatically completed. I understand that I would need to create the values but what to see if this has been done using STV. Regards Iain	ihmunro OFFLINE Expert Boarder Posts: 135 Karma: 0

Hi Iain,

STV lets you detect when a new selection has occurred, and gives you access to the value of this selection. From there, you can do anything you want. Here is some sample code:

 
- (void)tableViewModel:(SCTableViewModel *)tableViewModel
  valueChangedForRowAtIndexPath:(NSIndexPath *)indexPath
{
 SCTableViewCell *cell = [tableViewModel cellAtIndexPath:indexPath];
 if([cell isKindOfClass:[SCSelectionCell class]])
 {
  SCSelectionCell *selectionCell = (SCSelectionCell *)cell;
  NSInteger selectedIndex = [selectionCell.selectedItemIndex intValue];
 
  // your code here
  ...
 }
}

Hi, I was working on a quite similar problem as lain and thankfully found this thread. My only problem is that the valueChangedForRowAtIndexPath method never gets called when I change a value in my selectionCells. Thanks for any further help, Gerald	gerryka OFFLINE Fresh Boarder Posts: 5 Karma: 0

Hi Gerald, Are you sure you're conforming to the SCTableViewModelDelegate protocol in your view controller's header file? Also, is your selection cell in the main model, or is it in a detail model?	tarekskr OFFLINE Administrator Posts: 2404 Karma: 72

Yes the class is conforming to the protocol.

It is an automatically generated cell that is part of a SCClassDefinition.

 
	SCClassDefinition *reportClassDef = [SCClassDefinition definitionWithClass:[ReportObject class] 
														   withPropertyNames:[NSArray arrayWithObjects:@"reportName", @"table",
																			  @"dateFrom", @"dateTo", @"groupBy", nil] withPropertyTitles:[NSArray arrayWithObjects:@"Name",@"Table",@"Start date",@"End date",@"Group by",nil]];
	[reportClassDef propertyDefinitionWithName:@"reportName"].required = TRUE;
	[reportClassDef propertyDefinitionWithName:@"table"].type = SCPropertyTypeSelection;
	[reportClassDef propertyDefinitionWithName:@"table"].attributes = [SCSelectionAttributes attributesWithItems:[[ReportHelper sharedInstance] arrayOfTableNames] allowMultipleSelection:NO allowNoSelection:NO];

Thanks for your efforts!
Gerald
