If an input field contains a custom dialog box you can open the dialog box using the <b>F4</b> shortcut key. If the dialog box has several tab forms like a font dialog box does, you can use the TAB key to navigate through each tab form.</p> <h2>Validation</h2> <p>A default red frame automatically appears around an input component to act as a visual alert to let the user know that he or she entered invalid data. The default red frame's appearance can be customized using the <a href="C1.Win.C1InputPanel.4~C1.Win.C1InputPanel.C1InputPanel~ErrorFrameColor.html">C1InputPanel.ErrorFrameColor</a> and <a href="C1.Win.C1InputPanel.4~C1.Win.C1InputPanel.C1InputPanel~ErrorFrameThickness.html">C1InputPanel.ErrorFrameThickness</a> properties.</p> <p>In addition to the visual alert, you can also provide a text alert for invalid input. C1InputPanel has an <a href="C1.Win.C1InputPanel.4~C1.Win.C1InputPanel.InputComponent~ErrorText.html">InputComponent.ErrorText</a> property that displays the string you enter for the property as a ToolTip when you move the mouse over the input component.</p> <p>The following image shows the visual, and textual validation alerts being used:</p><br> <img border="0" alt="Description: C:\MyFiles\D2H2008Projects\WinForms\WinForms_C1InputPanel\Documents\Graphics\ErrorProviderExample.png" src="ImagesExt/image11_39.png" width="645" height="196"> <p> <a name="seealsobookmark"></a> </div> <div id="FooterContent"> <p> </p><p> </p><hr style="height: 1px"><p>Copyright © <script type="text/javascript"> var theDate=new Date() document.write(theDate.getFullYear()) </script> GrapeCity, inc.
