<h2>
FlexGrid Validation
</h2>
<p>
When you use the <b>CollectionView.getError</b> method for validation,
the <b>FlexGrid</b> will show errors in data cells and also in the
row header cells.
</p>
<p>
By default, the row header cells will show all the errors in the item.
To customize that behavior, return the error message you want to show
for the row header when <b>getError</b> is called without a specific
property (prop == null).
</p>
<p>
Try entering an invalid country or a negative number to see how the grid
identifies the error and prevents the invalid entry from being committed:
</p>
<wj-flex-grid [itemsSource]="view">
</wj-flex-grid>
<h2>
Forms Validation
</h2>
<p>
You can use the the <b>CollectionView.getError</b> property to validate forms as well. Simply call the function
and apply the result to the appropriate input element using the <b>setCustomValidity</b> method that is part of
the HTML5 validation API:
</p>
<form id="theForm" class="form-inline" (input)="validateForm($event.target)" (submit)="$event.preventDefault()">
<div class="form-group">
<label for="country">Country</label>
<input id="country" type="text" class="form-control" required value="US">
</div>
<div class="form-group">
<label for="downloads">Downloads</label>
<input id="downloads" type="number" class="form-control" required value="123">
</div>
<div class="form-group">
<label for="sales">Sales</label>
<input id="sales" type="number" class="form-control" required value="123">
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
