How Can I Add a DocumentVariableField to a Table Cell Programmatically

Hi,

We are creating a table which then gets inserted into a RichTextBox. We need to add a DocumentVariableField to one of the cells, can anyone please advise.

// The field which needs to be added o the table
            
doc_text.Document.DocumentVariables.Add("1001", addrName);
DocumentVariableField docVariable = new DocumentVariableField() { VariableName = "1001"  };
           
doc_text.InsertField(docVariable, FieldDisplayMode.Result);
            

RadDocument document = new RadDocument();
Section section = new Section();

TableWidthUnit w1 = new TableWidthUnit(100);
TableWidthUnit w2 = new TableWidthUnit(520);

Table table = new Table();
table.StyleName = RadDocumentDefaultStyles.DefaultTableGridStyleName;

TableRow row1 = new TableRow();
TableCell cell1 = new TableCell();
cell1.Background = Color.FromRgb(174, 255, 190);
cell1.PreferredWidth = w1;
cell1.Padding = new Telerik.Windows.Documents.Layout.Padding(3, 6, 3, 6);
Paragraph p1 = new Paragraph();
Span s1 = new Span();
s1.FontWeight = FontWeights.Bold;
s1.FontFamily = new FontFamily(CGlobals.docu_default_font);
s1.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
s1.Text = "Name";
p1.Inlines.Add(s1);
cell1.Blocks.Add(p1);
row1.Cells.Add(cell1);

TableCell cell2 = new TableCell();
cell2.Background = Color.FromRgb(174, 255, 190);
cell2.PreferredWidth = w2;
cell2.Padding = new Telerik.Windows.Documents.Layout.Padding(3, 6, 3, 6);
Paragraph p2 = new Paragraph();
Span s2 = new Span();
s2.FontWeight = FontWeights.Bold;
s2.FontFamily = new FontFamily(CGlobals.docu_default_font);
s2.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
            
s2.Text = addrName;  // We need to change this to the DocumentVariableField
p2.Inlines.Add(s2);
cell2.Blocks.Add(p2);
row1.Cells.Add(cell2);
table.Rows.Add(row1);

section.Blocks.Add(new Paragraph());
section.Blocks.Add(table);
section.Blocks.Add(new Paragraph());
document.Sections.Add(section);

doc_text.Document = document;

Many thanks

How to Programmatically add a Content Control to a Table Cell in RadRichTextBox

Hi,

We are creating a table and adding it to a RichTextBox:

        public void AddAddress()
        {
            string addrName = string.Empty;
            string[] rowName = new string[] { "Job Title", "Employer", "Address", "Tel.", "Tel. Dir.", "Mobile", "Email", "Website", "Fax", "Details", "Address", "Tel.", "Mobile", "Email", "Details" };

            Table table = new Table();
            table.StyleName = RadDocumentDefaultStyles.DefaultTableGridStyleName;

                s1.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
                s1.Text = rname;

                cell1.Blocks.Add(p1);
                row1.Cells.Add(cell1);

                cell2 = new TableCell();
                cell2.Background = Color.FromRgb(255, 255, 255);
                cell2.Padding = new Telerik.Windows.Documents.Layout.Padding(3, 6, 3, 6);
                p2 = new Paragraph();
                s2 = new Span();
                s2.FontFamily = new FontFamily(CGlobals.docu_default_font);
                s2.FontSize = Unit.PointToDip(CGlobals.docu_default_font_size);
                s2.Text = " ";
                p2.Inlines.Add(s2);
                cell2.Blocks.Add(p2);
                row1.Cells.Add(cell2);
                table.Rows.Add(row1);
            }

            section.Blocks.Add(new Paragraph());
            section.Blocks.Add(table);
            section.Blocks.Add(new Paragraph());
            document.Sections.Add(section);

            doc_text.Document = document;   
        }

How can we add a Content Control with StdProperties to one of the table cells, similar to:

SdtProperties sdtProperties = new SdtProperties(SdtType.RichText) 
{ 
    Alias = "AliasName", 
    Lock = Lock.SdtContentLocked, 
}; 
doc_text.InsertStructuredDocumentTag(sdtProperties);

TreeListView doesn't have a vertical scrollbar unless it's Height is fixed

I have the following XAML code:

<telerik:RadLayoutControl >
    <telerik:RadTabControl>
        <telerik:RadTabItem Header="Admin">
            <telerik:RadTabItem.Content>
                <telerik:RadLayoutControl>
				
                    <!-- Left Side -->
                    <telerik:RadTreeListView Name="TreeListView" ItemsSource="{Binding Arguments}">
                        <telerik:RadTreeListView.ChildTableDefinitions>
                            <telerik:TreeListViewTableDefinition ItemsSource="{Binding Children}" />
                        </telerik:RadTreeListView.ChildTableDefinitions>
                    </telerik:RadTreeListView>
					
                    <telerik:LayoutControlSplitter />

                    <!-- Right Side -->
                    <telerik:RadTabControl Width="Auto">
                        <telerik:RadTabItem Header="Tab 1">
                            <telerik:RadGridView></telerik:RadGridView>
                        </telerik:RadTabItem>
                        <telerik:RadTabItem Header="Tab 2">
                            <telerik:RadGridView></telerik:RadGridView>
                        </telerik:RadTabItem>
                    </telerik:RadTabControl>

                </telerik:RadLayoutControl>
            </telerik:RadTabItem.Content>
        </telerik:RadTabItem>
    </telerik:RadTabControl>
</telerik:RadLayoutControl>

The problem is that when I populate the TreeListView with big number of items, it stretches the topmost RadLayoutControl parent (look at the scrollbar position on the far right). The behavior I expect is that the TreeListView itself gets a vertical scrollbar like when I set it to a fixed Height. But I want it to be resizable with the window.

How can I achieve such behavior?

RadGridView CellEditTemplate Validation InEditMode invisible

Hey,

since the last Update, my GridViews with a CellEditTemplate (for example DateTimePickers or MaskedTextInputs) dont show the red Validation Error indicators anymore, if ValidatesOnDataErrors is set to InEditMode.

If you hover over the location where the error should show you can still see it, but no red indicator whatsoever.

If ValidatesOnDataErrors is set to ViewMode it works.
If no CellEditTemplate is set, it works too.

Heres the code of the gridview:

        <telerik:RadGridView
            x:Name="rgv"
            GroupRenderMode="Flat"
            ShowGroupPanel="False"
            FilteringMode="Popup"
            ShowSearchPanel="False"
            CanUserSearch="False"
            ValidatesOnDataErrors="InEditMode"
            AlternationCount="2"
            ActionOnLostFocus="CommitEdit"
            CanUserDeleteRows="True"
            IsSynchronizedWithCurrentItem="True"
            ShowColumnFooters="True"
            SelectionMode="Single"
            IsPropertyChangedAggregationEnabled="False"
            VirtualizingPanel.VirtualizationMode="Recycling"
            NewRowPosition="Top"
            AutoGenerateColumns="False"
            >
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn
                    DataMemberBinding="{Binding RechnungsNr}"
                    Header="Rechnung Nr."
                    TextWrapping="Wrap"
                    HeaderTextWrapping="Wrap"
                    Width="100"
                    >
                    <telerik:GridViewDataColumn.CellEditTemplate>
                        <DataTemplate>
                            <telerik:RadMaskedTextInput
                                Value="{Binding RechnungsNr, Mode=TwoWay, UpdateSourceTrigger=Explicit}"    
                                maskedInput:MaskedInputExtensions.MaxTextLength="255"
                                Mask=""
                                MinWidth="100"
                                InputBehavior="Insert"
                                IsClearButtonVisible="False"
                                />
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellEditTemplate>
                    <telerik:GridViewDataColumn.AggregateFunctions>
                        <telerik:CountFunction Caption="Anzahl:  " ResultFormatString="{}{0:N0}" />
                    </telerik:GridViewDataColumn.AggregateFunctions>
                </telerik:GridViewDataColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

And also the whole sample project:

PdfFormatProvider

I have a docx file and it contains line numbers like the image below.

When I use the PdfFormatProvider to convert the docx to pdf the line numbers do not display on the PDF. However, if I manually open the document and save as a PDF they do.

Is there something I am missing here?

RadWatermarkTextBox and EventToCommandBehavior

I'm trying to capture when the Enter key is pressed in a RadWatermarkTextBox without adding code to code-behind.

In the XAML I have:

            <telerik:RadWatermarkTextBox MinHeight="26"
                                         x:Name="searchCompleteBox"
                                         VerticalAlignment="Center"
                                         Text="{Binding SearchText, Mode=TwoWay}"
                                         Width="200" 
                                         WatermarkContent="Enter name, address, or ID">
                <telerik:EventToCommandBehavior.EventBindings>
                    <telerik:EventBinding Command="{Binding OnSearchCompleteBoxKeyDownCommand}"
                                     EventName="KeyDown"
                                     PassEventArgsToCommand="True" />
                </telerik:EventToCommandBehavior.EventBindings>
            </telerik:RadWatermarkTextBox>

In the ViewModel:

    private async void OnSearchCompleteBoxKeyDown(System.Windows.Input.KeyEventArgs e)
    {        
        if (e.Key == Key.Enter)
        {
            await SearchForMembersAsync();
        }
    }

The problem is SearchText is not updating. So if I type something like "smith" OnSearchCompleteBoxKeyDown fires five times, the if result is false five times, but SearchText contains an empty string instead of "smith".

SearchText is declared properly and is updated properly if I take the EventToCommandBehavior code out. This all works properly if I use code-behind but I want to avoid that.
