Hi all, I faced a problem with RadGridView in WPF

I have a collection of items, each of them contains collection of subitems

for this hierarchy I choosed to use main grid with HierarchyChildTemplate, where I placed another gridview for subitems

I use PropertyRelation for mapping child tables to master table

The problem is that AutoGenerateColumns="false" doesn't work for this child gridview, its columns are generated automatically anyways

Have anyone met this problem before or is there another way to display a master grid with grids for subitems?

Thank you

Alexander

DateRow conversion

Hi,

Based in the intergration sample I am trying to populate a chart from a grid. I have the following functions which I took from your sample. I have changed the function to use all records not just the selected ones.

    
                   private void ShowSelectedRecordsInChart()  
        
                    {  
        
                        DataTable table = new DataTable();  
        
                        DataColumn col = new DataColumn("Shuttle", typeof(double));  
        
                        table.Columns.Add(col);  
        
                        try 
        
                        {  
        
                            foreach (DataRecord item in this.datagrdV02.Records)  
        
                            {  
        
                                DataRow row = table.NewRow();  
        
                                row["Shuttle"] = ((DataRow)item.Data)["Shuttle"];  
        
                                table.Rows.Add(row);  
        
                            }  
        
                        }  
        
                        catch (Exception ex)  
        
                        {  
        
                            MessageBox.Show(ex.Message);  
        
                        }   
        
                    }

When I execure the following line:

row[

"Shuttle"] = ((DataRow)item.Data)["Shuttle"];

I get the following error:

Unable to cast object of type 'CoachTech.Test_VO2' to type 'System.Data.DataRow'.

Any Idea what I am doing wrong?

Cheers,
Kevin.

1) SelectedItem

2) SelectedRecord

3) SelectedRecords

4) CurrentCell

5) CurrentItem

6) CurrentRecord

Thanks,

GridViewColumn ignores background

Hi,

my problem is that when I define a GridViewColumn the value of Background is ignored!
BUT (and I use this as workaround) with GridViewDataColumn it works.

    
            <telerik:RadGridView.Columns> 
        
                                <telerik:GridViewColumn Width="115"  Background="Silver">  
        
                                    <telerik:GridViewColumn.CellTemplate> 
        
                                        <DataTemplate> 
        
                                            <TextBlock Text="Test" /> 
        
                                        </DataTemplate> 
        
                                    </telerik:GridViewColumn.CellTemplate> 
        
                                </telerik:GridViewColumn> 
        
                                <telerik:GridViewDataColumn Width="115" Background="Silver">  
        
                                    <telerik:GridViewDataColumn.CellTemplate> 
        
                                        <DataTemplate> 
        
                                            <TextBlock Text="Test" /> 
        
                                        </DataTemplate> 
        
                                    </telerik:GridViewDataColumn.CellTemplate> 
        
                                </telerik:GridViewDataColumn>

The first column in this snippet is not colored - the second is!

I just want to notice this problem - it is not stopping me or such bad things.

Regards

Manfred

Item selection problem.

Hi,

I'm using RadTreeView on WPF, .NET 3.5 SP1. My goal is to select an item in the treeview programmatically. For this purpose I tried the following:

tree.SelectedItems.Clear();

tree.SelectedItems.Add(item);

This works fine IF and ONLY IF this particular item was visible(expanded) at least once. Please help to resolve this issue. All I need is to select the item (no matter if it was expanded or not).

Thanks in advance,

Ruben.

Support for Item Selection

Hello,

I have a very simply implementation that embeds a radCarousel control on a grid and databinds the ItemSource to an Observable collection. The only way that I am able to select items is by clicking on the "scroll bar" buttons at the bottom of the control. I was under the impression that I should also be able to click on an item in the list as well to bring it to the front as the selected item. From the demos it appears that nothing special is required to support this functionality - am I missing something?

Thanks,
Mark.
