Creating a Customized Sorting User Interface:
Step 3-Adding the Separator Rows to the GridView’s Control Hierarchy
This step of the VIDEO TUTORIAL will demonstrate on how to over ride the native ‘Render’ method of CustomSortingUI.aspx web page at run time in the Page_Load event handler. This over riding of ‘Render’ method is necessary to inject separator rows based on a new category in the GridView control’s sortable display interface at run time. A detailed explanation of how the separator records are injected into the GridView’s control hierarchy is explained to accomplish our goal. Finally, the run time display of the CustomSortingUI.aspx web page exhibiting the customized sorting user interface with separator rows for each category is demonstrated to conclude this video tutorial. For detailed information and source code for this step, please refer to the original article.
