Hello,
I have a Word document in docx format and mail merge with Excel in xls format.
The following are mergefields that rendered properly in Word but not when I do mail merge in my code.
{ MERGEFIELD TODAY \@ “MM/dd/yy” }
{ MERGEFIELD BAL \# ####,0.00 }The following code:
using (Stream stream = new FileStream(docxPath +docxFilename, FileMode.Open))
{
stream.Seek(0, SeekOrigin.Begin);
byte[] bytes = new byte[stream.Length];
stream.Read(bytes, 0, bytes.Length);
templateDocument = new DocxFormatProvider().Import(bytes);
IEnumerable mailMergeSource = this.GetMailMergeDataSource(worksheet);
mergeDocument = templateDocument.MailMerge(mailMergeSource);
this.SaveFile(mergeDocument);
}Above is the main code that do mailmerge
The GetMailMergeDataSource is give below:
private IEnumerable GetMailMergeDataSource(Worksheet worksheet)
{
List<DynamicDataObject> mailMergeSource = new List<DynamicDataObject>();
string[] fieldNames = new string[worksheet.UsedCellRange.ColumnCount];
int columnCount;
int rowCount;
CellSelection selection;
for (columnCount = 0; columnCount < worksheet.UsedCellRange.ColumnCount; columnCount++)
{
selection = worksheet.Cells[0, columnCount];
fieldNames[columnCount] = selection.GetValue().Value.RawValue.ToString();
}
for (rowCount = 1; rowCount < worksheet.UsedCellRange.RowCount; rowCount++)
{
DynamicDataObject data = new DynamicDataObject();
for (columnCount = 0; columnCount < worksheet.UsedCellRange.ColumnCount; columnCount++)
{
selection = worksheet.Cells[rowCount, columnCount];
data.Set(fieldNames[columnCount], selection.GetValue().Value.RawValue);
}
if (columnCount > 0)
mailMergeSource.Add(data);
}
return mailMergeSource;
}
DynamicDataaObject is derived from Telerik own's sample document-processing-sdk-master > WordsProcessing
the SaveFile is below:
private void SaveFile(RadFlowDocument document)
{
using (Stream stream = File.OpenWrite(newDocxPath + newDocxFilename))
{
DocxFormatProvider formatProvider = new DocxFormatProvider();
DocxExportSettings exportSettings = new DocxExportSettings
{
AutoUpdateFields = true,
InvalidDocumentAction = InvalidDocumentAction.ThrowException
};
formatProvider.ExportSettings = exportSettings;
formatProvider.Export(document, stream);
}
}
It works. It merged into another docx document but the Merge Field format failed. But to do the same with Word merge, the resulting file shows proper format.
Let me know if you need full working sample that demo the problem.
Thank,
Coopbase

Hi,
I have a scatter point series with chart track ball enabled and SnapMode set to ClosestPoint, but with multiple series added to the chart I see a point per series.
Each colour in above image is a separate series added from code. The chart itself is in XAML.
<telerik:RadCartesianChart Grid.Row="0" BorderBrush="Transparent" Background="White" x:Name="radChartView" HorizontalAlignment="Stretch" VerticalContentAlignment="Stretch" DockPanel.Dock="Top">
<telerik:RadCartesianChart.Behaviors>
<telerik:ChartTrackBallBehavior ShowIntersectionPoints="True" ShowTrackInfo="False" SnapMode="ClosestPoint" />
</telerik:RadCartesianChart.Behaviors>
<telerik:RadCartesianChart.TrackBallLineStyle>
<Style TargetType="Polyline">
<Setter Property="Visibility" Value="Collapsed" />
</Style>
</telerik:RadCartesianChart.TrackBallLineStyle>
</telerik:RadCartesianChart>
I've only seen examples of SnapMode=ClosestPoint on LineSeries plots. Should this work on ScatterPointSeries?
Thanks,
Neil

I've used telerik rad diagram for creating a kind of blue-print system (flow system). In this flow-system we have a lot of nodes and connections. Is it possible to show connections like this?
At the moment it looks like this:
I've tried to work with the bezier-connection-type, but that didn't work as expected:
Thanks a lot!

Hey. Is there anyway that I can deploy the application without ClickOnce or any Installation but just copy the compiled file to the client machine?
Our company has very complicated and tedious IT process. The best one to deploy the project is just to copy the app to the client machine and run it.
BTW, it is .net core 3.1 WPF APP.

Hi,
I have a step line chart with the trackball enabled. The ChartTrackBallBehavior is like this.
<telerik:ChartTrackBallBehavior ShowIntersectionPoints="True" ShowTrackInfo="True" SnapMode="None" SnapSinglePointPerSeries="True"/>
My problem is that the closest point can be on the left or on the right of the trackball line. I need the closest point to be always the one on the left. Is there a way to change the default behavior so that I can programmatically set the closest point when trackball line moves? I have attached an image to better explain my problem.

Hello,
If we follow the WPF good practices, the `OnLostFocus` method must be called when the control loses focus and it's the job of this method to raise the `LostFocus` event.
In the case of the AutoCompleteBox, the event is raised, but the method is not called. So it's not possible to do some work before the event is raised.

Hello,
I have a problem to get the SelectedItems from my radcombobox. I have created an attached property "SelectedItemsHelper" to use the "SelectedItems" property. As a template for the attached property, I 've used this blog post.
My SelectedItemsHelper
using System.Collections;
using System.Windows;
using Telerik.Windows.Controls;
namespace WpfAutoQuery
{
public class SelectedItemsHelper
{
public static readonly DependencyProperty SelectedItemsProperty =
DependencyProperty.RegisterAttached("SelectedItems", typeof(IList), typeof(SelectedItemsHelper), new FrameworkPropertyMetadata((IList)null, new PropertyChangedCallback(OnSelectedItemsChanged)));
public static IList GetSelectedItems(DependencyObject d)
{
return (IList)d.GetValue(SelectedItemsProperty);
}
public static void SetSelectedItems(DependencyObject d, IList value)
{
d.SetValue(SelectedItemsProperty, value);
}
private static void OnSelectedItemsChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
var comboBox = sender as RadComboBox;
if (comboBox != null)
{
IList selectedItems = GetSelectedItems(comboBox);
if(selectedItems != null)
{
comboBox.SelectedItems.Clear();
foreach (var item in selectedItems)
{
comboBox.SelectedItems.Add(item);
}
}
}
}
}
}
My RadComboBox:
<telerik:RadComboBox Name="rcbSection" Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="2" Margin="10" IsEditable="False"
ItemsSource="{Binding Sections}" DisplayMemberPath="Line1" AllowMultipleSelection="True"
local:SelectedItemsHelper.SelectedItems="{Binding SelectedSections}">
</telerik:RadComboBox>My "SelectedSections" property in ViewModel
public ObservableCollection<Section> SelectedSections
{
get { return GetPropertyValue<ObservableCollection<Section>>(); }
set { SetPropertyValue(value); }
}I have added a jpg, where you can see that i dont get my selected values... Does someone can help me? I dont know what i do wrong...

I have recently been developing a radtreeview and needed the facility to only drop inside a folder, therefore eliminating the requirement for drop before and after. The link above resolved this issue, thank you, though I can still see the graphical orange indicator (line with circle) which is associated with the drop position.
Is it possible to disable this indicator as well?
As an aside issue, it appears that I get highlighted textblocks remaining behind after moving nodes around see the attached image. Do you have advice as to what could cause this?
