GridView auto date format

Hello,

I am using telerik:RadGridView, my Items is set to a DataTable.

the source Data tableis set to a SQL Query output, data is in a specific dateformat.

In case we setAutoGemerateColumns="true"; the data is displayed only in a modify format (thedata is date and time and the display automatic adds slashes, removes secondsand millisecond)

In the other case(AutoGemerateColumns="false") I have three columns specify and binded to each column;

the results are only visible by row count, the columns data is empty.

appreciate your advise,

Thank you

Adding items in VS2008

I'm obviously having a dumb day, but I can't seem to easily add items to my Outlook bar? I've added the two references to my project, then gone to my toolbox, chosen the RadOutlookbar and then drawn it on to my Window. I get the main part of the Outlook bar, but no items within the component. When I go to Properties, and click on the three dots next to the Items property I get the dialog box appear, but there are no items I can add, and the 'Add' button is grayed out.

Hilp!

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,
