So in a ListView I can do the following and in my View Model it would set the IsRowSelected property for each object when the row is selected. How can I do this with a RadGridView? We are using MVVM pattern and are trying to have little to no code in the xaml code behind.

Thanks

        <Style x:Key="RowItemStyle" TargetType="{x:Type ListViewItem}"
            <Setter Property="HorizontalContentAlignment" Value="Stretch" /> 
            <Setter Property="IsSelected" Value="{Binding Path=IsRowSelected, Mode=TwoWay}" /> 
            <Style.Triggers> 
                <MultiTrigger> 
                    <MultiTrigger.Conditions> 
                        <Condition Property="ItemsControl.AlternationIndex" Value="1" /> 
                        <Condition Property="IsSelected" Value="False" /> 
                        <Condition Property="IsMouseOver" Value="False" /> 
                    </MultiTrigger.Conditions> 
                    <Setter Property="Background" Value="#EEEEEEEE" /> 
                </MultiTrigger> 
            </Style.Triggers> 
        </Style> 
 
            <ListView  
                Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="5" 
                MaxHeight="200"  
                ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Auto" 
                ItemContainerStyle="{StaticResource RowItemStyle}" 
                ItemsSource="{Binding Path=MasterList}" IsSynchronizedWithCurrentItem="True" 
                SelectionMode="Single" 
            > 
                <ListView.View> 
                    <GridView> 
                        <GridViewColumn Header="Item Name" Width="Auto" DisplayMemberBinding="{Binding Path=ItemName}" /> 
                    </GridView> 
                </ListView.View> 
            </ListView>

Hello,

I have a WPF user control that has many RadGridView controls, and the RAM is shooting up to 700 MB usage, and it's taking a long time to process.  A little bit about the process:

I have a part of my app which loads similar result sets together.  So a result set is bound to a RadGridView dynamically.  I query the related data, then loop through the collection of result sets, and dynamically add RadGridView's for each result set.  For one partular result set collection, I may have 20 or more result sets with not a lot of data.

But for some reason, it's chugging along, and RAM usage is through the roof...  any ideas on how to make it perform better?

Thanks.

Hello,

I have a grid connected to a DataTable.

The grid and datatable both have three columns and three rows.

I want to make a cell in column A uneditable based on a value in a cell in column B
(both cells are in the same row).

I know that I can use BeginningEdit event to cancel an edit attempt in a cell,
however I was wondering if I can reach the same result using XAML trigers
and perhaps just a small relevant class.

Thanks,

Erez

I just downloaded the WPF RadControls and they look great.

However, there are two elements I need to create an application that seem to be missing - Printing, and a RibbonBar.

For printing, there are needs such as printing the Calendar, printing reports from data etc. 

The RibbonBar is also nice, as it makes the app look like an Office 2007 type app. (Though a lot of end users still don't seem to like the ribbon.)

Any advice on this would be appreciated.  I would like to build an app around these WPF controls, but if I can't print, it's not going to be marketable.

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

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.
