You must configure the data source so that it supports the automatic operations.
Rad Grid provides an API for inserting new data, updating existing data and deleting data from the specified data source.
You can use these features while writing very little code.
To enable/disable this feature you can use the Client Settings. Enable Caching property (its default value is false): With client-side caching enabled Rad Grid will store the start row index, maximum rows, sorting and filtering expressions and will retrieve them from the cache automatically on subsequent client-side refreshes. Need Data Source, Address Of Rad Grid1_Need Data Source Add Handler Rad Grid1.
The second client-side binding demo illustrates how to: Further information about the On Command/On Row Data Bound events of Rad Grid and the client Grid Table View object's properties, methods and collections can be gathered from the Client-side API Reference chapter in the documentation. Grid Need Data Source Event Args e) [Web Method] public static int Get Count(string filter Expressions) [Web Method] public static List Protected Overloads Overrides Sub On Init(By Val e As System. Column Created, Address Of Rad Grid1_Column Created End Sub Sub Rad Grid1_Column Created(By Val sender As Object, By Val e As Telerik.
For example the command name is "Do Insert" , then Rad Grid will fire Item Command Event and the event argument of the handler function (generally the "e" variable ) will have the same command name , i.e. By default it is fired by image buttons in the header item when Sorting is enabled.
The argument for the Sort Command must be the Data Field name for the Data Field to be sorted.
This examples can help you with this approach (look at the ASCX code): Editing/User Control Edit Form/Default The user control buttons Update and Cancel have Command Name property associated. When "Update" command bubbles, Rad Grid will fire first Item Command event, and if the event is not canceled (e.
Canceled set to false) then Rad Grid will fire Update Command event and then it will refresh automatically.
Later, when you bind it on the client side, previously created items will be populated with data. Since Rad Grid transfers - there is no proper way for populating the controls in these templates as they are templates.
If you bind the control on client with rows more than Page Size, Rad Grid will create new elements and populate properly the cells for certain columns. However, for the rows that are initially created on the server (these Page Size items), Rad Grid will manage to populate a control in Grid Template Column if the control in that Item Template has ID set equal to the Data Field property of that column.
When an event bubbles from a child control, Rad Grid will fire Item Command event. Item argument will be a reference to the Item which is the parent of the control raised the bubble event (i.e. Some command names are predefined in Rad Grid and the control will respond to them automatically (like the value of Rad Grid. Page Command Name) and command various arguments for different paging operations like the string "Next","Prev" or "First".
