I think we can start to formulate our answer to the question above by realizing where I Data Bind() and create my controls in relation to the workings of View State is why our data is lost on postback.So, the answer: Page Load is the wrong place to bind a Repeater or setup a dynamic control. View State has already tried to resync your controls but they weren’t created yet. Stop toying with me and tell me the answer I hear you say. If you bind there you’re controls will exist in time for View State to operate normally.In this example, we’ll go through a fully featured Grid View with editing, deleting, selecting, sorting, and paging functionality that is manually bound and identify the limitations and some of the workarounds. Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.
Test question: I have a form which binds data to a Repeater on Page Load. You may have found this page if you have been googling the following: until you Data Bind().
The Repeater’s Item Template contains a Text Box and Checkbox. Keeping that in mind, we should ask ourselves what is the order of execution of View State.

I would have also accepted Repeaters are the evil frogspawn of Satan and should never be used unless you find peeling off your fingernails with rusty pliers appealing. in my case on Init() didn’t do the job however you have pointed me in the right direction and I realized that the code should be in On Data Binding protected override void On Data Binding(Event Args e) (data binding for a control in a repeater) Due to their dynamic nature, they add an extra layer of complexity when dealing with custom controls. NET Page Lifecycle is required to get everything working in practice.
I have also come across a couple of others solutions that does the same.
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.
Stop(); If Not Is Post Back Then Session("Grid Table") = Nothing End If End Sub Protected Sub Rad Grid1_Need Data Source(By Val sender As Object, By Val e As Grid Need Data Source Event Args) Dim dt As New Data Table() dt.
The Grid View 'Grid View1' fired event Row Deleting which wasn't handled. When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind. NET 2.0 are familiar with how to deal with this, but since ASP.
NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.
