Rad Grid fires the Need Data Source event each time it needs to be bound to a data source.
If, at the time of the event, the Data Source property is not set to a valid data source object, the grid will not behave correctly.
protected void Rad Grid1_Need Data Source(object sender, Grid Need Data Source Event Args e) protected void Rad Grid1_Item Data Bound(object sender, Grid Item Event Args e) protected void Button1_Click(object sender, Event Args e) Protected Sub Page_Load(By Val sender As Object, By Val e As Event Args) 'Stopwatch sw = Stopwatch.

This is working fine for the first page of the parent grid, and only the parent's Need Data Source is fired. Grid Command Event Args e) public void Match Button_Click(object sender, Event Args e) You should never call . Data Bind() in a Need Data Source event; I'd guess that's causing at least some of your problems.
Also, the child nested grid's Need Data Source is correctly only firing upon expanding a row. Grid Need Data Source Event Args e) protected void Un Matched Client DBCustomers_Telerik Rad Grid1_Item Command(object sender, Telerik.
When you create the structure using the designer (in Visual Studio) there is less of a chance that mistakes will be made.
The more difficult and error-prone task is creating the structure programmatically.
When I am trying to implement that in radgrid I am getting too many errors.
What i want is once i edit the radgrid, i just want to catch the text in the textbox after i edited it. the above functionality i did in gridview as follows.
Page hey i have do this code protected void rg Product Name_Need Data Source(object source, Grid Need Data Source Event Args e) protected void rg Product Name_Update Command(object source, Telerik.
I'm using a nested Telerik Rad Grid, which should only be populated when a particular row in the parent Rad Grid is expanded.
Since Rad Grid saves all of its structure properties (Detail Tables, Columns, etc.) into the View State, building a Rad Griddynamically is a task very similar to creating and adding controls dynamically to a web page.
See following two scenarios offer possible approaches to dynamically create a Rad Grid that ensure that Rad Grid will behave normally. Detail Table Data Bind = new Grid Detail Table Data Bind Event Handler(this.
Therefore quite naturally the Need Data Source event will not get fired when you rebind the grid.
