How can I dynamically add dataobject to childgrid

[Auvo]

I'm using the radGridView and it's hierarchy feature. Because of large amount of data, I fetch data first to the upper/first layer of radGridView with empty sub data object to provide +-mark of beginning of each row (identify that there are sub data available). I'm using the Radgridview.ItemsSource property to add data to the grid.

But now I have problem when expanding one of the row and dynamically add the dataobject to the selected childgrids.itemssource, it's not showing. I'm using following code to add data to the selected childgrid

 

private void alarmsTbl_DataLoading(object sender, Telerik.Windows.Controls.GridView.GridViewDataLoadingEventArgs e)
{
        GridViewDataControl dataControl = (GridViewDataControl)sender;
        if (dataControl.ParentRow != null)
        {
            AlarmsServiceReference.AlarmDetails[] groupDetails = alarmsClient.GetAlarmGroupDetails(alarmsTableDef.DBType, alarmsTableDef.ConnectionString, sql);
            dataControl.ItemsSource = groupDetails;
        }
}

 

 

How I can dynamically add dataobject to the expanded childgrid?

Hi Auvo,

 May you please take a look at this forum thread? There is a sample project on how to load data related only for the row you have expanded with the "+".

All the best,
