Capture which resource is clicked on in timeline view

[Karl]

I have a scheduler control and want to know which resource header was clicked on when user click on a resource header cell.

Can someone please tell me how this is done?

Thanks.

Hi Karl,

Thank you for your question.

You can achieve this by handling the MouseClick event of RadScheduler and detecting which element was clicked. The following code snippet demonstrates this:

void radScheduler1_MouseClick(object sender, MouseEventArgs e)
{
    SchedulerResourcesHeaderElement resourceHeader = this.radScheduler1.RootElement.FindDescendant<SchedulerResourcesHeaderElement>();
    if (resourceHeader != null && resourceHeader.ControlBoundingRectangle.Contains(e.Location))
    {
        SchedulerCellElement clickedCell = this.radScheduler1.ElementTree.GetElementAtPoint(e.Location) as SchedulerCellElement;
        if (clickedCell != null)
        {
            foreach (Resource res in this.radScheduler1.Resources)
            {
                if (res.Name == clickedCell.Text)
                {
                    RadMessageBox.Show("You have clicked ResourceId: " + res.Id.KeyValue);
                    break;
                }
            }
        }
    }
}

I hope you find this useful. Feel free to ask if you have any additional questions.

is there anyway to get the resource id from the  clickedCell object?

this

if (res.Name == clickedCell.Text)

                {

would only work if all the resources had different text.  I have multiple resources that have the same cell text so it's always just pulling the first one.

Thanks!

Hello John,

Thank you for contacting Telerik Support.

You are able to modify the previous code snippet as follows:

private void radSchedulerControl_MouseClick(object sender, MouseEventArgs e)
{
    SchedulerResourcesHeaderElement resourceHeader = this.radSchedulerControl.RootElement.FindDescendant<SchedulerResourcesHeaderElement>();
    if (resourceHeader != null && resourceHeader.ControlBoundingRectangle.Contains(e.Location))
    {
        SchedulerCellElement clickedCell = this.radSchedulerControl.ElementTree.GetElementAtPoint(e.Location) as SchedulerCellElement;

        if (clickedCell != null)
        {
            GetResource();
        }
    }
}

public void GetResource()
{
    Point point = radSchedulerControl.PointToClient(Cursor.Position);
    SchedulerDayViewGroupedByResourceElement groupedDayViewElement = radSchedulerControl.SchedulerElement.ViewElement as SchedulerDayViewGroupedByResourceElement;

    if (groupedDayViewElement == null)
    {
        return;
    }

    foreach (SchedulerDayViewElement dayViewElement in groupedDayViewElement.GetDayViewElements())
    {
        int min = dayViewElement.ControlBoundingRectangle.X;
        int max = min + dayViewElement.ControlBoundingRectangle.Width;
        if (point.X >= min && point.X <= max)
        {
            EventId resource = dayViewElement.View.GetResources()[0].Id;
            MessageBox.Show(resource.KeyValue.ToString());
            return;
        }
    }
}

Please, have in mind that this code example is related to RadScheduler DayView.

I hope this information helps. Should you have further questions, I would be glad to help.
