Hi Folks,
I've got a RadGridView with a details view that itself contains three RadGridViews.
The problem is, events from the inner Grid e.g. SelectionChanged or MouseDoubleClick  are transported somehow to the outer Grid.
This leads to serious problems, for example the outer grid collapses the details when the user double clicks in the inner gridview..
How can I prevent the outer grid accepting events from controls of the details page ? 
(Is this a common event routing issue ?)

Best regards
Oliver

(P.S. or, vica versa, how to prevent the "inner" controls sending events to the outside? There's this structure: The outer grid contains a RadTabControl, some tabs, each tab contains a Grid which contains three RadGridViews and some buttons)

Hi,

I have a scenario where I need to update the layout of a RadGridView when I change the width of a column from my ViewModel.
My first approach was to use the ColumnWidthChanged event, but it does not fire.
Is this intended behavior?
I could trigger the UpdateLayout() call from my ViewModel, but it does not belong there because it is entirely UI related stuff...

Any suggestions?

Best Regards,
Christian

 

 

 

Hi,

As i was trying to create user control(Filtering) and want to attache with RAD GRID. Perhaps it's done but my events for Filtering is not getting fired. Can any one provide a small example for this with source code.

Hi,

I was asked to implement feature to find values in grid (user wants to see all rows so i cant use filters)
user wants (picture)
(1) field to input search text
(2) button to find all rows (kind of bookmark)
(3) button to iterate in find items (find next)

is there built in Search in grid (without filters) ?
I made this feature with this code:

private void btnFind_Click(object sender, RoutedEventArgs e)         {             btnFind.IsEnabled = false;             scrollIntoFindIndex = 0;             string searchText = txtFind.Text;             dgDynGrid.SelectedItems.Clear();             foreach (object o in dgDynGrid.Items)             {                 if (o is DataRowView)                 {                     for (int z = 0; z < (o as DataRowView).Row.ItemArray.Count(); z++)                     {                         try                         {                             string t = (o as DataRowView).Row.ItemArray[z].ToString();                             if (t.IndexOf(searchText, StringComparison.InvariantCultureIgnoreCase) >= 0)                             {                                 dgDynGrid.SelectedItems.Add(o);                                 break;                             }                         }                         catch                         {                             //if it cant be converted to string, i will not find in this field                         }                     }                 }             }             btnFind.IsEnabled = true;             ScrollIntoFind(0);         }         int scrollIntoFindIndex = 0;         private void ScrollIntoFind(int i)         {             if (dgDynGrid.SelectedItems.Count > i)             {                 dgDynGrid.ScrollIntoView(dgDynGrid.SelectedItems[i]);             }             else             {                 scrollIntoFindIndex = 0;                 MessageBox.Show("Završila je pretraga, idučim klikom se pretražuje od početka", "Kraj pretrage", MessageBoxButton.OK, MessageBoxImage.Information);             }         }         private void btnFindNext_Click(object sender, RoutedEventArgs e)         {             scrollIntoFindIndex++;             ScrollIntoFind(scrollIntoFindIndex);         }

but I am sure there must be better way to do this.
I would appreciate any hint

Thank you

I would like to disable editing action (editing appointment via double click). How to acomplish that?

I tried with:       
private void RadScheduler_AppointmentEditing(object sender, AppointmentEditingEventArgs e)
        {
            e.Cancel = true;
        }

but it doesnt work.

  Hi,

I need to maintain scroll position (both horizontal and vertical) when moving across pages.
I tried the following code , but was unable to achieve the desired functionality.
Even after calling RestoreScrollPosition() the scrollviewer didn't change its position.




private void btnNext_Click(object sender, RoutedEventArgs e)



{

SetScrollPosition();
BindData();

RestoreScrollPosition();







}







private void SetScrollPosition()



{



GridViewScrollViewer svSummaryInfo = (GridViewScrollViewer)rtSummaryInfo.FindChildByType<GridViewScrollViewer>();








_dbVerticalOffset = svSummaryInfo.VerticalOffset;
_dbHorizontalOffset = svSummaryInfo.HorizontalOffset;
}




private



void RestoreScrollPosition()



{


GridViewScrollViewer



svSummaryInfo = (GridViewScrollViewer)rtSummaryInfo.FindChildByType<GridViewScrollViewer>();





if (svSummaryInfo != null)



{



svSummaryInfo.ScrollToHorizontalOffset(_dbHorizontalOffset);

svSummaryInfo.ScrollToVerticalOffset(_dbVerticalOffset);

}
}

Please provide a code snippet for the same.

Hi Team,
I am using radDatafilter with custom inputs (date picker, combobox, checkbox), but i am unable to fire events when Input data changes. For example if user input is check box, then no event fire, similarly no event for  combobox selection change, i cant catch any event. kindly guide me raddatafilter event.
I posted some threads earlier, kindly consider that. Urgent response is highly appreciated.

I'm trying to figure out a good way to get a theme applied at design time. I followed someones suggestion to create a class like this and added it to the resources in my App.xaml.

I'm getting this error with RadExpander when i have that in place. The (few) other controls seem to be fine. Is there a good way of getting design time theme support application wide?

HI there,
I have a WPF application with MVVM. My main view has a RadDocking with multiple documents (MDI). The RadPanes are implicitly created through a coupling of the ViewModel with the RadDocking (I use the RadPaneGroupExtension from another forum post).
My RadDocking looks like this:

DepartmentView contains some Textboxes.
Unfortunately, the TextBoxes are readonly if instantiated this way. If I place the DepartmentView at another place (e.g. in a hardcoded RadPane in the above code), it works.

Since I have no clue where to search is any hint appreciated.

Regards

Mat
