I am trying to make the background color of the first row in my grid blue. here is what I am trying in c#.

 for (int i = 0; i < rgvAlarmLog.ColumnCount; i++)
                            {
                                rgvAlarmLog.Rows[rowCount].Cells[i].Value = HeaderRowSplit[i];
                                rgvAlarmLog.Rows[rowCount].Cells[i].Style.BackColor = System.Drawing.Color.Black;
                            }

I have another loop that goes through the rows and that is the rowcount variable. There is no visible color change when I do this. What am I doing wrong? It is a radgridview object. I have looked at similar post and tried their code to no avail. Any advice? Thanks

Hi,

I'm trying to implement a copy function.

In XAML I did the following:


How can I get access to the CommandParameter "copy" in the code-behind so that I can determine that a copy is needed instead of a regular AddNew?

Thanks in advance

I can't seem to get the DataForm to sync with the GridView.

I've got both controls bound via ItemsSource to the same collection in my viewmodel. But when the form loads in debug, there doesn't appear to be any records. If I create a header for the DataForm that displays Items.Count, it correctly shows the number of Items in the collection. But the current item isn't working. When I click on a Navigation button or the new button, I get the following error:

System.Reflection.TargetParameterCountException occurred
  Message=Parameter count mismatch.

Please help. I get the same error when I set the DataForm in the RowDetailsTemplate for the grid. in this situation it is triggered when I click on an item in the grid to select it and it tries to show the row details.

What are the possible Command Parameters for the the Align Command?

So far I have found the following:

• Left
• Right
• Top
• Bottom
• Center
• Middle

Are there any others?

P.S. Is there a date for when the Diagram control will be out of Beta?

The provided code to serialize a RadGridView with the PF will fail if the column header is not specified. I normally don't specify a column for the row details toggle columns.

I need to some help regarding the chart. I need to show clustered bar chart and have to add series dynamically. Below is my code that builds the chart..
=======================================================================================================
                    List<ChartDispayView> lineResultsList = new List<ChartDispayView>();
                    locChart.SeriesMappings.Clear();
                    
                    foreach (var line in vmRef.ChartLineMasterCollection)
                    {
                        if (line.IsChecked)
                        {
                            lineResultsList.AddRange(this.BuildLineViewChartData(line.LineName, vmRef.ChartResultsCollection.ToList()));

                            SeriesMapping sm = new SeriesMapping() { LegendLabel = line.LineName };
                            sm.ItemMappings.Add(new ItemMapping("PercentageLineOccupation", DataPointMember.YValue));
                            sm.ItemMappings.Add(new ItemMapping("Years", DataPointMember.XCategory));
                            sm.SeriesDefinition = new BarSeriesDefinition() { ShowItemLabels = true, ShowItemToolTips = true };
                            locChart.SeriesMappings.Add(sm);
                        }
                    }

                    locChart.ItemsSource = lineResultsList;
=======================================================================================================



It shouldn't create overwrite existing series.

Please guide me what i am doing wrong in the code and how to fix this issue.

Thanks

Hi,

How do I determine the current docked position of a RadSplitContainer?

I have content in a RadPane that I want to format depending on the current docked position of the pane in the RadSplitContainer (for example, a horizontal format when docked to the top or bottom and a vertical format when docked to the left or right and changing the ExpandDirection of expanders to match the current docked position). I've noticed there is a Friend property "State" that seems to contain the current docked position, however this property is not accessible publicly. What is the best way to obtain this information? (A dirty way would be to subclass RadSplitContainer and expose the State property publicly, but it feels like a particularly dirty way to get to this information).

Kind regards,
Dave.

Hello,

I am trying to do what I thought would be a simple implementation of the RadTransition and running into technical difficulties. I am building a kiosk app for us to use for a week. I load the main window with a grid and a frame in the grid. The frame source gets set to my *Start PAGE* which has 4 buttons on it. When I start the app the window loads (although you don't see it) and then the frame loads the start page. When a button is clicked on the start page in the event handler I want to get back to the main window frame where my RadTransition is and change the source to the page that corresponds to button clicked.As per your demo I use the SiteMap and SitePage models.

Now I would gladly add the new page to the SitePage and then Call SiteMap.SelectNextPage but I can't get a handle to it. I would update the source of the frame in the parent window but I can't get a handle to it either. So how do I go about getting the RadTransition to switch pages in WPF app?

Also I am not asking you to do my homework I just need to be pointed in the right direction.

TIA
JB

Tried uploading but the project too large so making a mock up for you to see. OK attached mock example....guess not. Can't upload zip to the forum. I put it here: http://www.gpgvm.org/wpfapplication1.zip
