RadRotator for ASP.NET AJAX: Using dynamic templates
My colleague Todd Anglin has already written a post about how to create a rotator control dynamically - you can read it here - How to Create RadRotator Programmatically. Unfortunately, this code in that post is for the old RadRotator control and if you try to use it in the new ASP.NET AJAX version, you will notice that it will not compile. Fortunately, you can quickly fix that. Here is what you need to change: FrameTemplate - this property has been replaced with ItemTemplate RadRotatorFrame - this object has been replaced with RadRotatorItem After you update the above names, you should be able...August 20, 2008

RadTips Episode 3: Client-Side Sorting in the RadGrid
In celebration of the fact that the weekend is upon us, I'd like to leave you all with another exciting RadTips episode. This episode covers yet another client-side databinding technique: sorting. Client-side databinding is an advanced feature of the RadGrid, and something only found in the latest and greatest bits from the RadControls for ASP.NET AJAX suite.

Internet Explorer JavaScript Performance Tip - use the "children" property
Today I was profiling the initialization time of RadTreeView for ASP.NET Ajax and found out that the biggest bottleneck was traversing the DOM tree. The code looks something like this: //get_childListElement() returns an HTML element var childNodes = parent.get_childListElement().childNodes; for (var i = 0, length = childNodes.length; i < length; i++) { var childNode = childNodes[i]; //Perform additional initialization } I tested with 10000 elements and in IE7 I got about 25000ms whilst in FireFox the total time was around 33ms (Core 2 Duo @ 2.33GHz). Quite a difference if you ask me. I thought that there may be some IE specific method/property which could perform better and I dug into MSDN. And a few minutes later I found the children property!!! Apparently the children collection contains only HTML elements (whilst childNodes is full of...August 14, 2008

How To: RadGrid hierarchy from objects hierarchy
Every once in a while we receive support about how to create hierarchical grid directly from objects hierarchy and I decided to post small example how to achieve this easily: protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e) { RadGrid1.DataSource = MyList; } protected void RadGrid1_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e) { e.DetailTableView.DataSource = MyList.Find( delegate(Master master) { return master.ID == Convert.ToInt32(e.DetailTableView.ParentItem.GetDataKeyValue("ID")); ...August 11, 2008
