GridView- How to restore state of grid detail rows if the user leaves a page and then returns back
This example demonstrates how to restore state of grid detail rows if the user leaves a page and then returns back.
To accomplish this task, perform the following:
1) Disable the page's cache as it is described in the Why controls do not work properly when clicking browser Back / Forward buttons article.
2) Handle the grid's DetailRowExpandedChanged event to save the expanded state. The session is used in this example.
[C#]</para><para>settings.DetailRowExpandedChanged=(s,e)=>{</para><para>if(e.Expanded)</para><para>rows.Add(e.VisibleIndex);</para><para>else</para><para>rows.Remove(e.VisibleIndex);</para><para>};</para><para>
3) Handle the grid's client-side Init event to send a get request to the server to see if it is necessary to expand rows.
[JScript]</para><para>function OnInit(s, e){</para><para> $.ajax({</para><para> type: "GET",</para><para> dataType: "text",</para><para> url: '@Url.Action("ShouldSendCallback", "Home")',</para><para> success: function(sendCallback){</para><para> if(sendCallback)</para><para> GridView.PerformCallback();</para><para> }</para><para> });</para><para>}</para><para>
4) Handle the grid's BeforeGetCallbackResult event to expand detail rows during the callback if necessary.
[C#]</para><para>settings.BeforeGetCallbackResult=(s,e)=>{</para><para>vargrid=sasMVCxGridView;</para><para>if(rows.Count!=grid.DetailRows.VisibleCount){</para><para>foreach(intiteminrows){</para><para>grid.DetailRows.ExpandRow(item);</para><para>}</para><para>grid.PageIndex=Convert.ToInt32(Session["curPage"]);</para><para>}</para><para>Session["curPage"]=grid.PageIndex;</para><para>};</para><para>

How to reorder ASPxTreeList sibling nodes, using buttons or drag-and-drop
This example demonstrates how to move TreeList nodes using buttons or Drag&Drop.
To persist the node order, it is necessary to set up an extra column to store node order indexes. Then, sort TreeList nodes by this column and deny sorting by other columns. This example stores this information in a dynamically created column and additionally, puts a dictionary "node key = node index" in the session. We have implemented this approach only for demo purposes. You can store this information in your DataSource.
Example Comments
Added By: darryl deen at: 12/12/2012 12:07:52 PM
Any example of this using your ASP.NET MVC extensions?
Also, is there an example where you can move all the nodes anywhere. i.e. move a child node to another parent in a specific spot/order?

How to use XtraReports in a WPF application
This example demonstrates how you can add an XtraReport to a WPF application, and show its print preview in a separate window.
Depending on your application design, you can invoke the Document Preview that displays a ready-to-print report document either by using the PrintHelper class or by assigning your report instance to the XtraReportPreviewModel object.

How to attach a client-side event with a dynamic argument to a template button
This example demonstrates how to embed a button into a grid cell, and attach a client-side Click event to it. The event calls a function, which gets the grid row key as a parameter. This function can be used to process the clicked row either on the client or the server.

How to show the ASPxLoadingPanel while the content is loading inside the ASPxSplitter pane
If you have an ASPXSplitter control and want to display content from another page in one of the panels, you can show a loading panel, reflecting this process. This example demonstrates how to use the ASPxLoadingPanel and iframe element for this purpose.
The ASPxLoadingPanel.Show method is called by the script when a page content is loaded. The ASPxLoadingPanel is hidden in the iframe.onload event handlers.

How to limit LayoutGroup customization at runtime
We have prepared an example demonstrating how to limit LayoutGroup customization at runtime.
To provide this functionality, we created a DockLayoutManager class descendant and the attached DisableCrossingGroupBoundaries property. The DisableCrossingGroupBoundaries property can be attached only to the LayoutGroup.
In this case, the LayoutGroup with the property assigned to true allows any customization and prevents moving inner elements outside LayoutGroup boundaries. For the LayoutGroup without this property, the default logic is used for arranging elements.

A custom toolbar button with Checked and DropDown styles
A custom toolbar button with Checked and DropDown styles
The BarButtonItem provides a ButtonStyle property. It allows you to make your button act like a check box or implement a down arrow that opens a dropdown control, for it. However, there is no option to activate the Check and DropDown button styles simultaneously. Here comes the XtraBars extensibility that allows you to create custom toolbar items with the required behavior.
This example shows how to implement a custom bar button that can stick in the pressed state and that also has a down arrow button to open a dropdown menu with additional commands or options.
