Hi.
I have a RadGridView that SelectionMode property is set to CellSelect.

After filtering by any column, when I try to get the row index of the selected cells, it gives me the index number in the rows created after the filtering process.

When I want to change the value of a cell using the obtained row index, this time it works according to the original table, not the filtered table.

So I have to get the original index number of that cell before filtering.

Hi, 

What is the method to clear or reset a layout diagram ?

I have tried the following without success ... 

        LayoutDiagram.DeselectAll()

        LayoutDiagram.Clear()

        LayoutDiagram.UndoRedoService.Clear()

        LayoutDiagram.Refresh()

Issue I am having is if there is a selected shape on the diagram, when I clear/re-add shapes, I am getting a strange side-effect where the shape's manipulation adorner becomes visible but the shape is no longer selectable. It looks like there is some "cache" behind the scenes that isn't clearing ? I would have expected LayoutDiagram.Clear is all I needed to call to reset to a "clean slate" ? Is this so ?

Kind regards,

Milan

Hello,

I want to use the LoadOnDemand feature of the RadTreeView.

But the NodesNeeded event gets executed on unwanted occasions, such as if I set the form's Enabled property to False, if I use the FindNodes method, or if I refer to the RadTreeview control.

The utility of loading on demand then becomes a defect for me.

It would be good if this event was executed only once, when you want to load the node.

Am I doing something wrong?

Excuse my English. I am Francophone.

Thank you

Hello,
I want to remove a row from the grid, I remove it from the DataSet but it doesn't refresh in the grid. How do I make the grid update after deleting a row in the DataSet?
Is there a better way to do it? Maybe deleting the row in the grid?
What is the best strategy to do it?
I only want to do this in memory, since the update in the database is done with ADO and SQL statements.

Best regards.

My code:

            DataRow[] drr = dsHojaCalculo.Tables[0].Select("key_guid = '"+ esteAEliminarGuid+  "' ");
            foreach (var fila in drr)
            {
                fila.Delete();
                dsHojaCalculo.Tables[0].AcceptChanges();
            }

            gridHc.DataSource = null;
            gridHc.DataSource = dsHojaCalculo.Tables[0];

I have it mostly working but am having one issue.  I am trying to get the rowinfo in the target grid where the files are dropped.   Grid 1 has a one to many relationship to grid 2.  I am trying to drag data from grid 2 to a different in row in Grid 1.  I want to get the serialID field of the target row in Grid 1, but have not been able to find a way to get that info. 

Thank you as always.

Hi,

I have put the calendar into a popupeditor, the purpose is to choose a "from" and "to" date for filtering data. For that reason I'm trying to only allow 2 selected dates. It doesn't seem to be so straight forward, currently I tried to prevent more than 2 selected dates in the SelectionChanged and SelectionChanging event by using e.Cancel = true and some other stuff also. But it's like the events doesn't detect it before too many dates are selected?

The best scenario would be if there's a way to disable the "drag selection" so that it's only possiple to select a date by clicking a date.

In any case, how can this behavior be achieved? 

Thanks in advance!

Hi. 

I tried to do the same for the example in this article, but there was no drop-down list. It also did not accept the values on the list.

I need to loop through all controls/elements and child controls/elements on a form and disable the control/element if the Tag property = "someText".

The following code works for controls and child controls on the form, but not for radRibbonBar elements. 

=================================================
foreach (var control in GetControlHierarchy(this))
            {
                if (control.Tag != null)
                {
                    if (control.Tag.Equals("someText"))
                    {
                        control.Enabled = false;
                    }
                }
            }

 private IEnumerable<Control> GetControlHierarchy(Control root)
        {
            var queue = new Queue<Control>();

            queue.Enqueue(root);

            do
            {
                var control = queue.Dequeue();

                yield return control;

                foreach (var child in control.Controls.OfType<Control>())
                    queue.Enqueue(child);

            } while (queue.Count > 0);
        }
======================================================

How would I change the above code to include radRibbonBar elements?

Thank you,
