Dear Support,

I want to Binding to GridView.SelectedItems.Count or other DependencyProperty, but it returns nothing, no error no exception. Please help me how to Binding in telerik:GridViewColumn.Footer.

Other test results:

• Binding to AggregateFunctions works fine.
• Binding to GridView.SelectedItems.Count or other DependencyProperty out of the range of GridView works fine.

Code is below:

Thanks for your support.

I am binding from a column header to some properties on a viewmodel. This binding is set up as shown:

                <telerik:GridViewDataColumn>
                    <telerik:GridViewDataColumn.Header>
                        <Grid>
                            <Grid.RowDefinitions>
                                <RowDefinition/>
                                <RowDefinition/>
                            </Grid.RowDefinitions>
                            <Label Grid.Row="0">Volume flow</Label>
                            <ComboBox Style="{StaticResource unitGridHeader}" Grid.Row="1" ItemsSource="{Binding Path=UnitVolumeFlow.AvailableUnits}"
                                          SelectedItem="{Binding Path=UnitVolumeFlow.CurrentUnit}" />
                        </Grid>
                    </telerik:GridViewDataColumn.Header>

The header is not populated with data when its shown, I also notice that there is no binding error output from Visual Studio. I've done a little research and I see that the DataContext from the grid is propagated to the DataGridViewColumn.DataContext. It seems like that binding evaluation is ignored entirely. What can cause this behaviour and how can I fix it?

Hi,

I'm something of a beginner and have built a WPF window that uses the RadDataForm. Everything works, so I don't have a specific problem, but am looking to see if there is a better solution than the one I've created.

Essentially, I'm creating an ObservableCollection and filling it with one record from the database using LINQ. My problem was that changes made to the OC in the dataform at runtime were not getting written back to the database. After a lot of googling, I have become thouroughly confused on the how to properly set this up, so came up with my own idea. I'm posting the code more as a peer review exercise rather than looking for a fix to an error.

The big question here is: Is there a better approach than the one I used?

AcctInfo.xaml.cs

AcctInfo.xaml

Again, this coding solution works with no problems, but I'm trying learn as I go and am fairly certain my solution is likely not the best one.

Thanks, Mark

Greetings,

How does one fetch the distinct values in a RadGridDataColumn as formatted via the binding's IValueConverter or StringFormat?  The rdGrid.GetDistinctValues(column, true, null) method returns the raw unformatted values.

Is there a clever or easy way to get the formatted values as displayed in the grid?

Thanks

I figured it out.  Here's how it can be done:

var distinctValues = uxGrid.GetDistinctValues(column, true, null);
var clip = string.Empty;
int count = 0;
Func<object, object> formatter;
if (column.DataMemberBinding.Converter != null) {
    formatter = _ => column.DataMemberBinding.Converter.Convert(_, column.DataType, null, CultureInfo.CurrentUICulture);
} else if (!string.IsNullOrEmpty(column.DataMemberBinding.StringFormat)) {
    formatter = _ => string.Format(_.ToString(), column.DataFormatString);
} else {
    formatter = _ => _;
}
foreach (var value in distinctValues) {
    clip += formatter(value) + "\n";
    count++;
}
clip = clip.TrimEnd('\n');
Clipboard.SetText(clip);

Is there a way to bind my gridview columns to different collections? I looking for independant column binding.

Something like :

GridView1.Columns(0).ItemsSource = colA
GridView1.Columns(1).ItemsSource = colB

Thanks

Hi, I am using RadMenu to create a three layer menu.
It is something like :    -TopMenu
                                        -SecondLevel1  -ThirdLevel
                                        -SecondLevel2  

Now, If I click "ThirdLevel" or "SecondLevel2", the menu will be closed automatically. But If I click "SecondLevel1", nothing happens. I know it is the logic you made it. But I want to close the menu when clicking "SecondLevel1". If there any way to do it?

I have an implicit style:


But i have to scroll up and down, and one after another each row cells turns green if it is supposed to.

How can i fix this?

I'm considering moving to Telerik grids.  One of the issues I've come up against is that it doesn't look like I can perform bindings which relate to the bound objects ToString() method.

With WPF Toolkit DataGrids I could have a binding on a list view which looked like:

Binding="{Binding}"

This would mean that the ToString() method on the relivant object in the bound collection would be called and displayed.

On Telerik controls if I perform a binding such as:

DataMemberBinding="{Binding}":

Then I do not see this behaviour.  Is this feature missing from your controls or do I have to approach this in another way?  This is something I would really like to be able to do as it allows me to display composite data in a single field.

Thanks

I'd like to expand all TreeListView nodes when the data is loaded. I tried to use DataLoaded event for it but got a problem. After calling ExpandAllHierarchyItems() in DataLoaded event handler, this event fires again and app goes into infinite loop. How can I handle with it? Note: I need expanded tree after each data update, not only once.

I have a TreeListView and simple data binding with PropertyChanged notification. Selecting a ComboBox value causes updating of node's child elements in the tree but sometimes cells don't get updated. PropertyChanged() invoked, actual value changed but no reaction from grid. New values appear only after scrolling or shrinking\expanding tree node. I suppose this strange behaviour is due to cells virtualization but don't know how to fix it.
