Additional question, I'm adding a dropdownprovider on one of the dynamically added columns but it doesn't seem to be doing anything, do you see anything that sticks out? 

var wddProvider = new DropDownProvider()
{
ID = "wdd" + col.Key
};
wddProvider.EditorControl.DataSource = selectionValues;
wddProvider.EditorControl.DataBind();
wddProvider.EditorControl.DataKeyFields = "SelectionValue";
wddProvider.EditorControl.ValueField = "SelectionValue";
wddProvider.EditorControl.TextField = "SelectionValue";
wddProvider.EditorControl.DisplayMode = DropDownDisplayMode.DropDownList;
grdTestResults.EditorProviders.Add(wddProvider);

grdTestResults.Behaviors.EditingCore.Behaviors.CellEditing.ColumnSettings.Add(new EditingColumnSetting(grdTestResults.GridView)
{
ColumnKey = col.Key,
EditorID = wddProvider.ID
});

I think I figured this out. I've got the page load

if (Session["data"] != null)
{
grdTestResults.DataSource = (DataSet)Session["data"];
grdTestResults.DataBind();
}

Then in the row updating I'm doing my updates then re-querying the data then doing a clear datasource and reseting.

grdTestResults.GridView.ClearDataSource();
grdTestResults.DataSource = (DataSet)Session["data"];
grdTestResults.DataBind();

Is this the preferred way to do this?

Separate question; I've got a NumericEditorProvider I can't get it to postback on value change when the cell is left through either the RowUpdating or the OnValuechanged event.

<ig:NumericEditorProvider ID="grdTestResults_NumericEditorProvider1">
<EditorControl ClientIDMode="Predictable" DataMode="Decimal" OnValueChanged="OnValueChanged">
<AutoPostBackFlags ValueChanged="On" />
</EditorControl>
</ig:NumericEditorProvider>

Thanks again

If you need the DB let me know

Thanks

Hello Anthony,

can you please send me the whole project with the code behind, so that I will be able to investigate the problem with the Manual CRUD?

Yana, got a follow up question which should hopefully be simple. I'm using manual crud and trying to updating after each cell change. I've got that pretty much working except when the the RowUpdating event fires and I do my manual updates the grids datasource is being set in the page load with the dataset (like your example has it) and then the grid displays the old info.

Any thoughts or better ways to do this?
