Custom keyboard navigation enables you to control how users interact with the grid. For example, you can prevent users from navigating to read-only columns or cells with null values. In a hierarchical grid, you could set up navigation between parent and child grids. To add custom keyboard navigation you would need to handle the <b>KeyDown</b> event and then add code to override the default navigation with your customized navigation.</p> <p><strong>Adding the KeyDown Event Handler</strong></p> <p>Complete the following steps to add the <b>KeyDown</b> event handler:</p> <ol> <li>Switch to Code view and add an event handler for the KeyDown event, for example:</li> <li>Switch to Source view and add the event handler to instances of the C1DataGrid control, for example:</li> </ol> <p><c1:C1DataGrid x:Name="c1DataGrid1" AutoGenerateColumns="True" <b>KeyDown="c1DataGrid1_KeyDown"</b>></c1:C1DataGrid></p> <p>You can now add code to the <b>KeyDown</b> event handler to customize the default navigation. For an example, you can take a look at the hierarchical grid example (<b>C1_MDSL_RowDetail</b>) in the <b>ControlExplorer</b> sample.</p><!--DXMETADATA end--> <a name="seealsobookmark"></a> <!--DXMETADATA start type="FilteredItemList" scrap="CATEGORISED_LINKS" namespace="linkcategory" source="Item" filter="" NoHeader="True" NoFooter="True" format="%%replaceinquotes:value=false%%%%scrap:name=_COLLAPSIBLE_HEADER,idprefix=seealso,caption=""%%phrase:name=SeeAlso%%%%designlist:tagidentifier=seealso,itemtype=See Also%%""%%%%filtereditemlist%%</div>"--><!--DXMETADATA end--> </div> <div id="FooterContent"> <!--DXMETADATA start type="Scrap" condition="communityenabled" name="_COMMUNITY_FOOTER" --><!--DXMETADATA end --> <!--DXMETADATA start type="Variable" name="CopyrightNotice" format="<p> </p><p> </p><hr style=""height: 1px"" /><p>%%variable%%</p>" --><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.
