Clearing Grid ItemsCollection

[Roger]

I have a grid that I bind in a NeedDatasource and I need to clear the items in the grid from outside the NeedDataSource.

I've tried the below, and grid.items.count doesn't change.

Me.rgProductModelSizeSubmittalDrawing.DataSource = Nothing
Me.rgProductModelSizeSubmittalDrawing.DataBind()

As mentioned by many other posts that I've read, a .clear would be really nice.

Hello Roger,

Try the following line code snippet to clear the RadGrid.

Vb.Net:

Me.rgProductModelSizeSubmittalDrawing.DataSource = New String() {}
Me.rgProductModelSizeSubmittalDrawing.Rebind()

-Shinu.

I've already tried that, it didnt' work either.

Thanks for the suggestion

Hello Roger,

The NeedDataSource event is fired when a call to the grid's Rebind method takes place. If you want to clear the datasource of the grid based on some condition, this should happen in the NeedDataSource event handler:

Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource
    If 'some condition
        RadGrid1.DataSource = New String() {}
    End If
End Sub

I hope this helps.

All the best,

Hi Jis,

You can try the following code snippet to empty your radgrid.

JS:

var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
masterTable.set_dataSource([]);
masterTable.dataBind();

Thanks,
