Hi,

What do I need to configure so that when ever user clicks a child item of the hierarchical grid SelectedItem is fired?

This is what I am observing

Parent 1
Child A
Parent 2
Child B

When selecting Child A SelectedItem is fired. Selecting Child B SelectedItem is fired as well. The problem is that Child A is still selected. How can unselect Child A.

I have read in this forum that the child and parent SelectionMode are independent.  Is there a way to tie them together?  I only want ONE record shown as selected regardless of whether it is a parent or child.

if * and BOLD means "selected/highlighted", this is what I am seeing:

* Parent 1
   * Child A
   * Child B
Parent 2
   * Child C
   * Child D

What I desire is if I clicked on Child A again is for all other rows to be deselected and ONLY Child A is highlighted, no parent records selected, no other children.   I would like SelectionMode = Single across all data relations.  Is this possible?

Parent 1
   * Child A
    Child B
Parent 2
    Child C
    Child D

I would show an image but I guess you can't do attachments in the forum.

Thanks in advance!

Is there a way to Cancel in the middle of editing an item in the RadDataForm?  
When I click on the Add Button, both the Commit Button and Cancel Button are enabled, so I can cancel out of creating a new record.
When I click on the Edit Button, the Commit Button is enabled, but the Cancel Button is grayed out.  

I am binding an ObservableCollection of objects to the RadDataForm ItemsSource property which gets loaded in the WindowLoaded event handler, and reloaded after adding, editing or deleting an item in the collection.   

I would like the user to be able to cancel an editing operation where the item being edited reverts to its previous state if the user clicks the Cancel Button.  Is this possible?

I have a simple gridview as follows:

<telerikgridview:RadGridView ScrollViewer.HorizontalScrollBarVisibility="Disabled" x:Name="ActivitiesGrid" IsReadOnly="True" AutoGenerateColumns="False" SelectionMode="Extended" ItemsSource="{Binding SelectedPatient.Activities}" ShowGroupPanel="False" RowIndicatorVisibility="Collapsed" ShowColumnHeaders="False" SelectionChanged="ActivitiesGrid_SelectionChanged">
  <telerikgridview:RadGridView.Columns>
      <telerikgridview:GridViewDataColumn DataMemberBinding="{Binding ActivityDate}" Header="{lex:LocText S3.ParametersUE.PatientManagement:UIStrings:PatientDetailsView_GridActivityHeaderDate}" DataFormatString="{}{0:dd/MM/yyyy}" MinWidth="100"/>
      <telerikgridview:GridViewDataColumn DataMemberBinding="{Binding Description}" Header="{lex:LocText S3.ParametersUE.PatientManagement:UIStrings:PatientDetailsView_GridActivityHeaderDescription}" />                                                
  </telerikgridview:RadGridView.Columns>
</telerikgridview:RadGridView>

If the text of Description is long, a horizontal scrollbar appears. How can I make sure that no horizontal scrollbar appears, but that the text is wrapped so that it is full visible in the column?

Hi! I am testind yours RadTreeView Control and i have a big problem. I want to use TriState tree and i have my global checkbox style.
Global style for checkbox is:

The problem is that on default my checkboxes dont have IsThreeState property set to true. When i add simple RadTreeView i can see my style in checkboxes BUT indetermine state doesnt work. I can see onl;y checked or unchecked checkboxes If i hardcode property
<Setter Property="IsThreeState" Value="True">
All works fine but in this case i have problem with RadGridView because in filter i have tri state checkboxes.
Sample Rad tree:

Thanks for help

I just downloaded the latest production version and upgraded my project and have run into manu issues within 2 min of running my application. On the tabcontrol, the selected item is behaving differently.  If you run your databinding example for the tab control and use the "x" to close the tabs you'll notice there is no selected item afterwards.  If you run the 2010 demo it works fine.  I am using Prism and MVVM and have a solution that works with the 2010 Q3 release but now does not work now that I have upraded (similar to how I explained it worked in your demo).

Hi,

I am using GridViewBoundColumnBase.GetValueForItem() to get the content of the cell in my RadGridView.
When I create the columns like the following:

everything works fine.

When I omit  the "xy" in new Binding("xy") to bind to the DataItem itself, GetValueForItem(..) returns the bound dataitem instead of the result of the used converter.

This behavior is quite unexpected. When I don't omit the "xy" I get the result of the converter as expected.

Is this a bug or am I doing something wrong?

Best Regards,

Hi there,

I'm busy evaluating the RadRichTextBox for our purposes and I've noticed that the InsertTable() method does not exist in the WPF version of the RadRichTextBox (vs SilverLight, which has the only documentation for this control).

I also noticed, regardless of it's existence in the API, that there is no way to specify a position for the table, regardless of where you might want to actually insert it in the document.

Could you please explain how, for example, I might programmatically insert a table into a RadDocument at a position which is in the middle of a paragraph?

The functionality I'm after is similar to how you would in a FlowDocument call InsertParagraphBreak() on a TextPointer and then insert the table in the Blocks section after the now preceeding Paragraph object.

Hello,

I'm using RadGridView with ComboBoxColumns and RowDetailsTemplate like this :

Everything works great including editing rows with ComboBoxColumns, but there is a little problem - after I expand specific row, I'm not able to edit that row with ComboBoxColumn anymore (even If I've collapsed it) - there's a red rectangle around - seems like a validation that stops me.

I'm using 2010 Q2 SP2 and LINQ datasources as listed below:


Thanks for any help

            myDataColumn.ColumnName = "Name";
            myDataTable.Columns.Add(myDataColumn);
            myDataTable.Rows.Add("1");
            myDataTable.Rows.Add("2");
            myDataTable.Rows.Add("3");
            radGridView1.ItemsSource = myDataTable;
