How To: Telerik RadGrid client-side caching with client-side binding to web services using LINQ to SQL
My new example illustrates how to cache the grid data client-side based on the current grid state. To do this we need to build a state key using current page index, page size, sort expressions and filter expressions: function getCacheKey(tableView) { return String.format("{0}{1}{2}{3}", tableView.get_currentPageIndex(), tableView.get_pageSize(), tableView.get_sortExpressions().toString(), tableView.get_filterExpressions().toDynamicLinq()); } Every time when we get new data we can store the result in our client-side cache: function updateGrid(result) { var stateKey = getCacheKey(tableView); if (!cache[stateKey]) { cache[stateKey] = result; } tableView.set_dataSource(result); tableView.dataBind(); } and when the next grid command occur we can call explicitly updateGrid() method if we have already saved result for the current grid...September 19, 2008 -

We would once more ask for your opinion on an ad we recently...September 19, 2008 -

Showing "tooltips" for the Nested RadGridView in RadMultiColumnComboBox
I promised that I will continue the "tooltips" series by demonstrating a "HOWTO" approach with our RadMultiColumnComboBox component. So what is the big difference with RadComboBox? What is really different is that RadGridView uses temporary elements to render grid cells, that are recycled every time you change something inside the screen estate of the RadGridView (say like scrolling). This means that setting the TooltipText properties of the cells in design time or through the API won't work. The solution That leaves us with the second approach only: to use the ToolTipTextNeeded event to get the job done. Here is a small example...September 18, 2008 -
