Problem sorting datetime column

Hello again,

I've got two more issues

1)
When I bind the radgridview to a linq to sql datacontext and do sorting on a datetime column, then I get the following error:

SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.

2) In your demo application, under DataSourceUpdates, there goes something wrong in my opinion.
When you edit a textbox, the binding with the gridview.CurrentItem doesn't function anymore. Also after resetting the form, the text won't disappear. I think this has something to do with the oneway binding. I solved the problem by using the selectionchanged event instead of binding the textboxes to the CurrentItem

With kind regards,
Thomas

RadChart Spline with two coordinates

Hello,

Can you explain me how to precisely place a point onto the chart with the X and Y coordinates ? Must I set two items mapping and a 2-dimensional array ?

I wrote this sample in Xaml :

    
            <!-- Chart --> 
        
            <t:RadChart Grid.Column="2" x:Name="_uiChart"> 
        
                <t:RadChart.SeriesMappings> 
        
                    <!-- Measurement --> 
        
                    <t:SeriesMapping CollectionIndex="0" LegendLabel="Measurement" x:Name="_uiMeasurementSeriesMapping"> 
        
                        <t:SeriesMapping.SeriesDefinition> 
        
                            <t:SplineSeriesDefinition /> 
        
                        </t:SeriesMapping.SeriesDefinition> 
        
                        <t:SeriesMapping.ItemMappings> 
        
                            <t:ItemMapping DataPointMember="YValue" />

                        </t:SeriesMapping.ItemMappings> 
        
                    </t:SeriesMapping> 
        
                </t:RadChart.SeriesMappings> 
        
            </t:RadChart>

And I passed to the ItemSource a double array like this :

    
            List<double[]> itemsSource = new List<double[]> 
        
            { 
        
                new double[] {3, 5, 9, 8} 
        
            }; 
        
            this._uiChart.ItemsSource = itemsSource;

Thanks,
Adrien.

Vertical Scrollbar issue after editing a row

Hi,

When I edit a value in a cell contained in the last rows of my grid (meaning the grid is vertically scrolled down) and then click on another row to validate the edited row, the vertical scrollbar automatically goes up showing the first lines of my grid.

If i set the EnableFiltering property to false it resolves the problem but i need this feature in my grid.

Is it a bug or is there any property to set to fix this issue ?

Thx

Insert new row with tabkey

Hello,

Is it possible to automatically insert a new row after tabbing out of the last cell of the radgridview?
Furthermore when I press enter after I edit a cell the cell stays in editmode. But after pressing enter in the new row the cell gets out of editmode. My itemssource is an observablecollection.

With kind regards,
Thomas

Problem with row validation

Hi,

When I insert or edit a row and tab to the end of the row, the row gets validated and e.olddata holds correctly the old data. But when I change the content of a cell and after that I click on another row, e.oldata holds the actual rowdata. This is not the behavior you would expect.

DataRow Visibility

I am looking for a way to hide certain rows based on properties of the row's datacontext. I've tried setting the MinHeight property of the row (as suggested in another thread). The problem is the row has text and shrinks to the text height. Is there some other way to control the visibility of individual rows in the grid?
