how to call on button click event the RadGrid1_RowDetailsVisibilityChanged event

[kumar p]

hi,
 i am  developing an nested  RadGrid . in my  first  column i have  place  an button . so that once  user  clicks on that button i need  to call the  RowDetailsVisibilityChanged event
 so that i can get the row unquie keyID  there based on that  i will be  retrieving  further  records  from the DB.
the below  code  shows  how  i used  to  do in  microsoft silverlight 4. the same  concept i need  to archive in  telerik control
i  tried  chaging  RowDetailsVisibilityMode ="Collapsed", VisibleWhenSelected, Visible in xaml   but still i am not able  to able the   

RowDetailsVisibilityChanged event

 here i  am using for four  RadGrid placed inside each other. this is  the  concept  i am using  to achive.

  <telerik:RadGridView.RowDetailsTemplate>
                <DataTemplate>
// here i am placing  my second datagrid.
             </DataTemplate>
</telerik:RadGridView.RowDetailsTemplate> 


 </DataTemplate>
            </telerik:RadGridView.RowDetailsTemplate> 


private void ExpandLevel1_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                Button btnExpandCollapse = sender as Button;
                Image imgScore = (Image)btnExpandCollapse.FindName("img1");
                // the original source is what was clicked.  For example  
                // a button.
                DependencyObject dep = (DependencyObject)e.OriginalSource;
                // iteratively traverse the visual tree upwards looking for
                // the clicked row.
                while ((dep != null) && !(dep is DataGridRow))
                {
                    dep = VisualTreeHelper.GetParent(dep);
                }

                // if we found the clicked row
                if (dep != null && dep is DataGridRow)
                {
                    // get the row
                    DataGridRow row = (DataGridRow)dep;
                    // change the details visibility
                    if (row.DetailsVisibility == Visibility.Visible)
                    {
                        imgScore.Source = new BitmapImage(new Uri("/Images/la1.png", UriKind.Relative));
                        row.DetailsVisibility = Visibility.Collapsed;
                    }
                    else
                    {
                        imgScore.Source = new BitmapImage(new Uri("/Images/a2.png", UriKind.Relative));
                        row.DetailsVisibility = Visibility.Visible;
                    }
                }
            }

            catch (Exception ex)
            {
                throw ex;
            }
        }

 now. once  user  clicks the button   i need to call the RowDetailsVisibilityChanged event  which is not  happening  and
also perform expand/ collpase operation  clicking on the button

 any help   how  to achive this   would be  greatly appreciated.

 thanks
 kumar

Hello,

You can use the same approach with RadGridView however you will need to change DataGridRow to GridViewRow.

                Button btnExpandCollapse = sender as Button;
                Image imgScore = (Image)btnExpandCollapse.FindName("imgLevel1");
                // the original source is what was clicked.  For example  
                // a button.
                DependencyObject dep = (DependencyObject)e.OriginalSource;
                // iteratively traverse the visual tree upwards looking for
                // the clicked row.
                while ((dep != null) && !(dep is RadRowItem ))
                {
                    dep = VisualTreeHelper.GetParent(dep);
                }

                // if we found the clicked row
                if (dep != null && dep is RadRowItem)
                {
                    // get the row
                    RadRowItem row = (RadRowItem)dep;
                   
                    // change the details visibility
                    //.Visibility = Visibility.Collapsed;
                   
                    if (row.RowIndicatorVisibility == Visibility.Visible)
                    {
                        imgScore.Source = new BitmapImage(new Uri("/Images/down_side.png", UriKind.Relative));
                        row.RowIndicatorVisibility = Visibility.Collapsed;
                    }
                    else
                    {
                        imgScore.Source = new BitmapImage(new Uri("/Images/left_side.png", UriKind.Relative));
                        row.RowIndicatorVisibility = Visibility.Visible;
                    }
                }
              
            }

Hi,

As I said in my reply you should use DetailsVisibility with GridViewRow not RowIndicatorVisibility with RadRowItem.
