Setting RadCombobox ItemsSource at runtime for EditorTemplate

Hey,

We are trying to use RadPropertyGrid for a configurable application where we don't know the objects at design time. At runtime we are using PropertyDefinition for each field. This is working well except when we need to create a RadComboBox and assign the ItemsSource at runtime. This is the function to create the "Generic" DataTemplate and the only question we have is how to set the ItemsSource on the newly created RadComboBox (it is the codedValueDomain parameter).

Thanks,
Mano

private DataTemplate GetDataTemplate(Esri.ArcGISRuntime.Data.FieldInfo fieldInfo, CodedValueDomain codedValueDomain)

{

StringBuilder stringBuilder = new StringBuilder();

stringBuilder.Append("<DataTemplate ");

stringBuilder.Append("xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' ");

stringBuilder.Append("xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' ");

stringBuilder.Append("xmlns:telerik='http://schemas.telerik.com/2008/xaml/presentation'>");

if (codedValueDomain != null)

stringBuilder.Append(string.Format(@"<telerik:RadComboBox Name=""comboBox"" SelectedValue=""{{Binding Attributes[{0}], Mode=TwoWay}}"" DisplayMemberPath=""Value"" SelectedValuePath=""Key"" HorizontalAlignment=""Stretch"" />", fieldInfo.Name));

else if

(fieldInfo.Type == FieldType.Integer || fieldInfo.Type == FieldType.Double || fieldInfo.Type == FieldType.SmallInteger || fieldInfo.Type == FieldType.Single)

stringBuilder.Append(string.Format(@"<telerik:RadNumericUpDown Value=""{{Binding Attributes[{0}], Mode=TwoWay}}"" HorizontalAlignment=""Stretch""/>", fieldInfo.Name));

else if (fieldInfo.Type == FieldType.Date)

stringBuilder.Append(string.Format(@"<telerik:RadDateTimePicker SelectedValue=""{{Binding Attributes[{0}], Mode=TwoWay}}"" HorizontalAlignment=""Stretch"" InputMode=""DatePicker""/>", fieldInfo.Name));

else

stringBuilder.Append(string.Format(@"<telerik:RadMaskedTextInput Value=""{{Binding Attributes[{0}], Mode=TwoWay}}"" TextMode=""PlainText"" Mask="""" HorizontalAlignment=""Stretch""/>", fieldInfo.Name));

stringBuilder.Append("</DataTemplate>");

DataTemplate dataTemplate = System.Windows.Markup.XamlReader.Parse(stringBuilder.ToString()) as DataTemplate;

return dataTemplate;

}

RadTimePicker PropertyChanged event called twice with wrong value the second time.

Hi there,

I'm using RadTimePicker inside RadDataFilter. My RadTimePicker is using TimeSpan data type and using SelectedTime property. When i change the time using the time picker control button and then i clicked on one of the time options, it works properly. However, if i change the time manually using the textbox of the radtimepicker, the PropertyChanged event will be called twice. First time it is called, the value is correct, but the second time, it will be an "UnSet" value. Is this a bug or is there some setting that must set to make it work properly.

Hope to hear from you soon.

Thank you

QCV - "any" filter on child entities

I have a list of customers, and each customer itself has a list of contacts. To check if either the customer or a contact contains a certain name I would do the following query (in Entity Framework and LINQ):

query.Where

(cust => cust.Name.Contains(filter) ||

cust.Contacts.Any(contact => contact.LastName.Contains(filter)));

Which means: look inside the customer.Name or every contact belonging to the customer and look inside contact.LastName if it contains the filter-string.

Big question: how can this be done by creating a (Composite-) FilterDescriptor so that a QueryableCollectionView gets filtered correctly? First part is easy, but the second part "cust.Contacts.Any(...)" makes me a headache.

Regards
Neils

RaisePropertyChanged does not work in catch if there is a throw

the Code below is Bound to IsExpanded of RadTreeItem





public

bool IsExpanded

{

get

{

return isExpanded;

}

set

{

try

{

if (isExpanded != value)

{

if (value)

{

if (Children.Contains(dummy))

{

Children.Remove(dummy);

}

LoadChildren();

}

isExpanded = value;

RaisePropertyChanged(() => IsExpanded);

}

catch (Exception e)

{

if (!HasItems)

{

//if empty, add dummy to keep the expander.

Children.Add(dummy);

}

//any exception will keep this node collapsed.

isExpanded = false;

RaisePropertyChanged(() => IsExpanded);

throw;

}

}





Inside the catch statement, I want to force collapse the treeitem if there is an error. If I put "throw" the tree item DOES NOT collapse. when I remove the "throw" it collapses successfully. Why "throw" is preventing the treeitem to collapse? 





We need the "throw" because IsExpanded is called by another method that catches the exception and do some logic.

RadChart - Data is not displayed near the edges of the chart

I'm working on a WPF application and using the Telerik RadChart control.I'm having the following issue:

see demo2.JPG

The number is not displayed for the first and last columns/series.

When I have less columns, everything works great, as in the demo3.JPG

I'm not sure what causes that, and really hope to get any suggestions (maybe its a lack of space, but I'm not sure how to solve that). Thanks!

How to enable filtering while radgridview loads

Hello,

I would like that the users would be able to add filters while the grid loads asynchronously (loads a lot of data for ~10 seconds). Any ideas on how to make this possible as while the grid loads the filter-combobox is empty.
