[kim]

Hi,

 

GanttView has 2 columns

I change value on the screen TEXT1

I want change TEXT2 value without raising ganttView_ItemChanged event

 

GanttViewElement.Columns.Add(new GanttViewTextViewColumn("A", "TEXT1");

GanttViewElement.Columns.Add(new GanttViewTextViewColumn("B", "TEXT2");

ganttView_ItemChanged(object sender, GnattViewItemChangedEventArge e)

{

    if(e.PropertyName.Equals("TEXT1"))

    {

          var view = e.Item.DataBoundItem as DataRowView;

         view["TEXT2"] = "Test";   

     // this code is call ganttView_ItemChanged

    

}

Hello, Kim, 

When an item's property is changed, it is normal that the ItemChanged event is fired if you have a subscription to it. In order to avoid it, you can unsubscribe from the event before setting the new value and then subscribe to it again. Here is demonstrated a sample code snippet:

private void radGanttView1_ItemChanged(object sender, GanttViewItemChangedEventArgs e)
{
    if (e.PropertyName.Equals("TEXT1"))
    {
        var view = e.Item.DataBoundItem as DataRowView;

        this.radGanttView1.ItemChanged -= radGanttView1_ItemChanged;
        view["TEXT2"] = "Test";
        // this code is call ganttView_ItemChanged
        this.radGanttView1.ItemChanged += radGanttView1_ItemChanged;

I hope this information helps.
