Validate a Group of Controls
WinValidator™ allows you to validate a single control, validate all controls associated with WinValidator, as well as validate a group of controls. You can create a group of controls by instantiating a new instance of a ValidationGroup object. Once created, you need to add this object to the WinValidator’s ValidationGroups collection.
WinValidator extends a ValidationSettings object to each control to manage validation tasks. Exposed by this object is a ValidationGroup property. You can set this property to a valid ValidationGroup. ValidationGroups allow you to validate controls that have similar conditions are purposes. With ValidationGroups, you can also manage the order of validation if you set the ValidationTrigger to programmatic.
The following example code demonstrates how to create a ValidationGroup, add two controls to it, and then validate the group.
' Create a new group and add it to WinValidator.
Me.UltraValidator1.ValidationGroups.Add( _
New Infragistics.Win.Misc.ValidationGroup("TextGroup"))
' Get the ValidationSettings objects for two TextBox controls.
Dim vs1 As Infragistics.Win.Misc.ValidationSettings = _
Me.UltraValidator1.GetValidationSettings(Me.textBox1)
Dim vs2 As Infragistics.Win.Misc.ValidationSettings = _
Me.UltraValidator1.GetValidationSettings(Me.textBox2)
' Create a new condition that will fail validation
' if the text in the TextBox starts with "ultra".
Dim condition As Infragistics.Win.OperatorCondition = _
New Infragistics.Win.OperatorCondition( _
Infragistics.Win.ConditionOperator.DoesNotStartWith, _
"ultra")
' Set the conditions on the two ValidationSettings objects.
vs1.Condition = condition
vs2.Condition = condition
' In an appropriate method or event, validate
' the group by passing in the group's key.
Me.UltraValidator1.Validate("TextGroup")
// Create a new group and add it to WinValidator.
this.ultraValidator1.ValidationGroups.Add(
new Infragistics.Win.Misc.ValidationGroup("TextGroup"));
// Get the ValidationSettings objects for two TextBox controls.
Infragistics.Win.Misc.ValidationSettings vs1 =
this.ultraValidator1.GetValidationSettings(this.textBox1);
Infragistics.Win.Misc.ValidationSettings vs2 =
this.ultraValidator1.GetValidationSettings(this.textBox2);
// Create a new condition that will fail validation
// if the text in the TextBox starts with "ultra".
Infragistics.Win.OperatorCondition condition =
new Infragistics.Win.OperatorCondition(
Infragistics.Win.ConditionOperator.DoesNotStartWith,
"ultra");
// Set the conditions on the two ValidationSettings objects.
vs1.Condition = condition;
vs2.Condition = condition;
// In an appropriate method or event, validate
// the group by passing in the group's key.
this.ultraValidator1.Validate("TextGroup");
