<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>
<wjGrid.FlexGrid itemsSource={this._view}>
</wjGrid.FlexGrid>
<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" className="form-inline" onInput={e => this._validateForm(e.target)} onSubmit={e => e.preventDefault()}>
<div className="form-group">
<label htmlFor="country">Country</label>
<input id="country" type="text" className="form-control" required defaultValue="US"/>
</div>
<div className="form-group">
<label htmlFor="downloads">Downloads</label>
<input id="downloads" type="number" className="form-control" required defaultValue="123"/>
</div>
<div className="form-group">
<label htmlFor="sales">Sales</label>
<input id="sales" type="number" className="form-control" required defaultValue="123"/>
</div>
<button type="submit" className="btn btn-primary">Submit</button>
</form>
</div>;
