The detailsview detailsview1 fired event itemupdating which wasn t handled

I have a set of records that are returned from SQL Server and what I was doing is binding them to a POCO. You have to write below code into event in code behind like To fix this, I had to take a closer look at my datasource and datakeys.

Data Bind() End Sub For Paging you can use On Page Index Changing for this....

Details View Change Mode: private void Handle Cancel() { bool is Bound To Data Source Control = Is Bound Using Data Source ID; Details View Mode Event Args e = new Details View Mode Event Args(Default Mode, true); On Mode Changing(e); if (e.

Cancel) { return; } if (is Bound To Data Source Control) { Mode = e. Empty); } Requires Data Binding = true; } private void Handle Edit() { if (Page Index With Change Mode you are choosing that the control switch to one of it's modes.

When it starts to performing this task, the Mode Changing event is raised (to indicate that it's in progress) (optionally do something here).

New Page Index Load Employee List() 'FUNCTION FOR DATASET grd Employees.

I've found an answer in other forum, and though I didn't find the code of Form View, I've found a Details View implementation and I think in this case it might be similar.

Basically what I've understood of it, is that the Mode Changed/ing events are raised when command buttons are clicked (Cancel, Edit, Insert, New and Update), i.e.when one doesn't have direct control over these events, and when we use the Change Mode method, we know that the mode has changed (or will be changed) and it would make no sense of raising an event..protected void Grid View1_Page Index Changing (object sender, Grid View Page Event Args e) { Grid View1. New Page Index; bind Grid View(); //bindgridview will get the data source and bind it again } private void bind Grid View() { Grid View1. Data Bind(); } protected void Grid View1_Page Index Changing(object sender, Grid View Page Event Args e) { Grid View1. New Page Index; bind Grid View(); //bindgridview will get the data source and bind it again } protected void Page_Load(object sender , Event Args e) { if(! protected void Grid View1_Page Index Changing(object sender, Grid View Page Event Args e) { //string s1 = "select * from master"; //Data Set ds = Sql Helper.

This class had several public properties of type Integer. I replaced their type with a string instead to bypass the casting issue.
