Dynamicly create new tab and copy controls to it from existing tab

Hi all,
I want to the user to press a button and it will create a new tab. The controls on that new tab will be the exact controls of the existing tab, plus I want to copy some content over from the old to the new. How do I create a new tab dynamically with the same page layout and controls of an existing tab?

RadChart Designer Crash

This may be related to the other crash we are seeing with the Runtime, but this is far easier to reproduce:

1. Make a new windows app project.
2. Drag RadChart control onto form, leave default settings.
3. Vertically size the chart to make it smaller - once small enough, the entire development environment will crash (hard lock).

This appears to be related to the Legend, because I can size the chart down to the size of the legend, but if I go any smaller, it crashes.

EDIT: This was performed using Visual Studio 2005 Version 8.0.50727.867 (vsvista.050727-8600) on Windows Vista 32-bit (no SP1).

No scrolling in design mode

Hi,

I use tabpages with autoscroll.
When I design the pages and the control is small enough I see the scrollbars.
But I can't scroll in design mode.

With the normal forms control this works!!

Where do I find my trial license key?

The installer said at the end I could enter my trial license key which is good for 30 days so it suppresses the trial warning dialog. Where can this trial license key be found?

Retrieving values from selected rows

Hi All,

I have a pretty simple task that I am having trouble accomplishing. I have a GridView that has agent information. In a hidden column if the GridView I have the AgentId. I want to allow the user to select a cell (or multiple cells) and click a delete button, which will delete these users from a database.

I am having trouble retrieving the cell values of the selected cells. This should something thats easy to do, so I am guessing that I am just missing something here.

As always, thanks in advance for the help!

DropDownSizingMode always UpDownAndRightBottom

Hi,

I place a Combobox on a Winform.
I selecte none for DropDownSizingMode. This seems to be default, since the thext is no longer bold.

I build my project - and after it I have DropDownSizingMode again as UpDownAndRightBottom.

If I select an other value (UpDown for an example) it keeps this state.
So it looks like as if the DDSM is not set - it sets itselft to UpDownAn....

I don't need this mode - so I always (after every build) have to reset it :(
Of course I can do this in FormLoad - but I guess this is more a bug than a normla behaviour.

Regards

Manfred

Adding template relationships

I have an ConfigurationGroup object that contains ConfigurationGroupParameters. I want to display this in an hierarchic Grid. The relationship between the parameters and their configuration group is built dynamically as I receive data from my server.

Upon my first setParameters, the grid view displays my Groups as expandable, but no data is available when I try to expand them (and no sub grid appears). Upon my second receive I am able to display the parameter sub grid in my grid, but data is only available for the first Configuration group, the second, most recent set, group becomes empty.

I tried to do a work around by adding a dummy relationship with unique name after adding a parameter group. This made my data visible after the first receive. But on the second receive the m_GridView.Relations.Add() row throws an exception (Object set to null).

Is there something obvious missing in the code below, or is this a bug?

    
                    public void SetConfigurationGroupParameters(ConfigurationGroup configurationGroup)  
        
                    {  
        
                        m_GridView.GridElement.BeginUpdate();  
        
                        bool isNewConfigurationGroup = !m_ParameterBinder.ContainsKey(configurationGroup); 
        
                        #region Get Template  
        
                        GridViewTemplate template = null;  
        
                        if (isNewConfigurationGroup)  
        
                        {  
        
                            template = new GridViewTemplate(m_GridView);  
        
                            template.AllowAddNewRow = false;  
        
                            m_ParameterBinder.Add(configurationGroup, template); 
        
                            #region Create Columns  
        
                            template.AutoGenerateColumns = false;  
        
                            template.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;  
        
                            Collection<GridViewColumn> columns = CreateColumns(Presenter.GetParameterColumns());  
        
                            foreach (GridViewColumn column in columns)  
        
                            {  
        
                                template.Columns.Add(column);  
        
                            } 
        
                            #endregion  
        
                        }  
        
                        template = m_ParameterBinder[configurationGroup]; 
        
                        #endregion  
        
                        if (configurationGroup.Parameters != null)  
        
                        {  
        
                            template.DataSource = configurationGroup.Parameters; 
        
                            #region Arrange Relationship  
        
                            GridViewRelation relation = new GridViewRelation(m_GridView.MasterGridViewTemplate);  
        
                            relation.RelationName = "ConfigurationGroupsParameters." + configurationGroup.ConfigurationGroupOId;  
        
                            relation.ParentColumnNames.Add("ConfigurationGroupOId");  
        
                            relation.ChildColumnNames.Add("ConfigurationGroupOId");  
        
                            relation.ChildTemplate = template;  
        
                            m_GridView.Relations.Add(relation);  
        
                            m_GridView.MasterGridViewTemplate.ChildGridViewTemplates.Add(template); 
        
                            #endregion  
        
                        }  
        
                        m_GridView.GridElement.EndUpdate();  
        
                    }

RadGridView.RowsChanging not firing when row is being deleted

RadGridView.RowDeleting is marked Obsolete with an indication to use RowsChanging instead. However, RadGridView.RowsChanging is not triggered when the user deletes the row from the grid context menu.
