This row has been removed from a table and does not have any data

Hello,

First, I already found this same topic under Forums -> WinForms -> GridView, but that thread does not answer to my problem.

I have radGridView1 binded to DataTable. I can add new rows to grid and delete rows from grid.
Error "This row has been removed from a table and does not have any data. BeginEdit() will allow creation of new data in this row." occurs when I remove latest row I have added.

Here is the code which removes selected row:

    
            private void button2_Click(object sender, RoutedEventArgs e)  
        
                    {  
        
                        List<DataRow> itemsToRemove = new List<DataRow>();  
        
                        foreach (DataRow item in this.radGridView1.SelectedItems)  
        
                        {  
        
                            itemsToRemove.Add(item);  
        
                        }  
        
                        foreach (DataRow item in itemsToRemove)  
        
                        {  
        
                            ((DataTable)this.radGridView1.ItemsSource).Rows.Remove(item);  
        
                            ((DataTable)this.radGridView1.ItemsSource).AcceptChanges();  
        
                        }  
        
                        DataTable emptyTable = new DataTable(); // this is for refreshing grid view  
        
                        radGridView1.ItemsSource = emptyTable;  // this is for refreshing grid view  
        
                        radGridView1.ItemsSource = myDataTable;  
        
                    }

Can you help me from here?

Drawing a goal line without using the LineSeries

Hello,

Is there anyway to draw a line on a chart either verticleor horizontal on a chart without using a LineSeriesDefinition? I need something that is flexible enough to allow me to draw a goal line that actually touches both sides of the chart without starting in the middle and forcing me to set the layout mode to something that looks funny for a bar graph. Also I need something that works in conjunction with a HorizontalStackedBarSeriesDefinition.

Thanks,

Sean

Navigation Pane in Demo App

Hello,

It might be just because it is late, but I cannot seem to find the code for the control that is driving the navigation of the RadControls for WPF application. I am referring to the panel on the left side of the screen just under the Search box. It contains a hierarchy of demo pages to visit. It looks like it might be a RadPanelBar, but I cannot confirm this. Can someone help me out and perhaps point me to where this is implemented in the demo app?

Thanks,
Mark.

Option for different headers?

Is there an option/way to display different headers based on the current expanded state of the window similar to what is currently done with the content? If not, this would be a great feature to add.

Thanks,

Filter Carousel Items

Hello!

I find myself in a situation when I can have up to 100 carousel items and I really need to filter those elements by some of their content for example in FirstLook demo - the employee name.
I already saw a nice feature like this in filtering a GridView(Search as you type example)
How can this be possible for RadCarousel?

Thank you!
Roxana
