I am trying to learn WPF, the problem is I need to learn XAML first. In System.Windows.Controls.TextBox class, there is property 'FontFamily'. I will have to set a font for it. In one of my book I saw But where can I get this font(Verdana). Where is list of all font's in MSDN Library?

You can bind to the string name of the font as shown below as font.Name. The following code is loading up a ComboBox of all the fonts.
var installedfonts = new InstalledFontCollection();
int idFont = 0;
foreach ( var font in installedfonts.Families )
{
var fonttype = new LookupSelectItem { Id = idFont, Name = font.Name };
FontTypeList.Add( fonttype );
++ idFont;
}

Similar questions were asked many times, but I cannot quite make them work. How would I create C# version of the following xalm statement:
<h:TubeVisual3D x:Name="PipeVisual" Path="{Binding Pipe.Path}"
TextureCoordinates="{Binding Pipe.TextureCoordinates}"
Diameter="{Binding ElementName=PipeDiamSlider, Path= Value }"
Material="{Binding Pipe.Material}"
BackMaterial="{Binding Pipe.Material}"
ThetaDiv="50" IsPathClosed="False"
Visible="{Binding ElementName=PipeIsVisibleCheck, Path=IsChecked}"/>
Where “TubeVisual3D” is a 3D WPF element defined in Helix Toolkit and most of the parameters bound by the binding are dependency properties in “TubeVisual3D”.
The equivalent to your markup would be this:
HelixToolkit.Wpf.TubeVisual3D pipeVisual = new HelixToolkit.Wpf.TubeVisual3D();
BindingOperations.SetBinding(pipeVisual, HelixToolkit.Wpf.ExtrudedVisual3D.PathProperty, new Binding("Pipe.Path"));
BindingOperations.SetBinding(pipeVisual, HelixToolkit.Wpf.ExtrudedVisual3D.TextureCoordinatesProperty, new Binding("Pipe.TextureCoordinates"));
BindingOperations.SetBinding(pipeVisual, HelixToolkit.Wpf.TubeVisual3D.DiameterProperty, new Binding("Value") { Source = PipeDiamSlider });
BindingOperations.SetBinding(pipeVisual, HelixToolkit.Wpf.MeshElement3D.MaterialProperty, new Binding("Pipe.Material"));
BindingOperations.SetBinding(pipeVisual, HelixToolkit.Wpf.MeshElement3D.BackMaterialProperty, new Binding("Pipe.Material"));
pipeVisual.ThetaDiv = 50;
pipeVisual.IsPathClosed = false;
BindingOperations.SetBinding(pipeVisual, HelixToolkit.Wpf.MeshElement3D.VisibleProperty, new Binding("IsChecked") { Source = PipeIsVisibleCheck });
I have a comboBox in XPages which is showing an hierarcal list of categories and values populates as a vector in SSJS.
I now want to apply a styleheet (bold) to the categories (i.e on only the categories of the generated option tags)
please note that I do not need a lesson in how stylesheets work. I need to know how to add a class or style to the categories in the outputted options tags
how can I do that?
thanks

UPDATED MY QUESTION WITH A WORKING CLASS
Mimics a categorized view with 3 columns in a comboBox, category, label and value
public class Utils {
public static List<SelectItem> getGroupedComboboxOptions() {
try {
Database db = ExtLibUtil.getCurrentDatabase();
View vv = db.getView("ProdukterByCat");
Vector v = vv.getColumnValues(0);
List<SelectItem> groupedOptions = new ArrayList<SelectItem>();
SelectItemGroup group;
for (int i = 0; i < v.size(); i++) {
List<SelectItem> options = new ArrayList<SelectItem>();
group = new SelectItemGroup(v.get(i).toString());
ViewEntryCollection nvec = vv.getAllEntriesByKey(v.get(i), true);
ViewEntry entry = nvec.getFirstEntry();
while (entry != null) {
SelectItem option = new SelectItem(entry.getColumnValues().get(2).toString(),entry.getColumnValues().get(1).toString());
options.add(option);
entry = nvec.getNextEntry(entry);
}
group.setSelectItems(options.toArray(new SelectItem[options.size()]));
groupedOptions.add(group);
}
return groupedOptions;
} catch (NotesException e) {
e.printStackTrace();
}
return null;
}
}
A combobox in XPages is rendered using a HTML select tag. If you organise the options in optgroup's (see also Populating selectItems of the combobox (label, value) using a managed bean) you get some default styling out of the box. Example here.
You can even apply additional styling on them with standard CSS by targeting the optgroup. But support for that is limited: it doesn't work on an iPad for example.
If you want more control on how your dropdowns look, I'd suggest to use a plugin like Select2.
Is there an easy/straightforward way to dynamically add (not edit the value of) multiple checkbox controls in a .docx document body?
I tried appending a single SdtContentCheckBox after a new paragraph like this but with no luck:
newParagraph.Append(new SdtContentCheckBox());
and also followed the instructions here:
https://www.codeproject.com/Tips/370758/Add-dynamic-content-controls-to-a-word-document and here: How do I create a check box in C# using Open XML SDK
The first one showed only how to add a text content control and the second one straight up resulted in a corrupted .docx file.
Any help would be appreciated!
Closest working code I could find was this:
https://social.msdn.microsoft.com/Forums/office/en-US/f6ce8ecf-0ed8-4f18-958a-a086f212d1e2/how-to-create-a-checked-checkbox-form-field-using-the-sdk?forum=oxmlsdk
public static Paragraph GenerateParagraph()
{
var element =
new Paragraph(
new Run(
new FieldChar(
new FormFieldData(
new FormFieldName(){ Val = "Check1" },
new Enabled(),
new CalculateOnExit(){ Val = BooleanValues.Zero },
new CheckBox(
new AutomaticallySizeFormField(),
new DefaultCheckboxFormFieldState(){ Val = BooleanValues.Zero }))
){ FieldCharType = FieldCharValues.Begin }),
new BookmarkStart(){ Name = "Check1", Id = 0 },
new Run(
new FieldCode(" FORMCHECKBOX "){ Space = "preserve" }),
new Run(
new FieldChar(){ FieldCharType = FieldCharValues.End }),
new BookmarkEnd(){ Id = 0 },
new Run(
new Text("My check box"))
){ RsidParagraphAddition = "00784880", RsidRunAdditionDefault = "00B77989" };
return element;
}
Using this I was able to dynamically add Legacy Checkboxes (i.e. neither Content control nor ActiveX control), but at least it is a start!
If someone knows how to add Checkbox Content controls, feel free to post a reply below and I'll mark it as Correct.
Even though you found yourself the answer, I'll leave this here in case anyone stumbles upon this looking for something related.
There's a tool called Open XML SDK 2.5 Productivity Tool, which you can download from here that allows you to reverse-engineer a word .docx document to obtain the C# code to generate it from scratch.
In order to get the code that you are looking for to generate any kind of word element (a checkbox, a table, a bulleted list...), you need to create a word document with said element and save it.
Then, open it using the Open XML SDK 2.5 Productivity Tool and click on the "Reflect Code" button. The generated code will show you how to create those elements, styles and other formatting included.
With that, I got the code necessary to get a paragraph with a checkbox
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
using A = DocumentFormat.OpenXml.Drawing;
using DW = DocumentFormat.OpenXml.Drawing.Wordprocessing;
using PIC = DocumentFormat.OpenXml.Drawing.Pictures;
public static Paragraph GenerateCheckboxParagraph(string internalName, int internalId, string textAfterTextbox)
{
var run1 = new Run(
new FieldChar(
new FormFieldData(
new FormFieldName() { Val = internalName },
new Enabled(),
new CalculateOnExit() { Val = OnOffValue.FromBoolean(false) },
new CheckBox(
new AutomaticallySizeFormField(),
new DefaultCheckBoxFormFieldState() { Val = OnOffValue.FromBoolean(false) }))
)
{
FieldCharType = FieldCharValues.Begin
}
);
var run2 = new Run(new FieldCode(" FORMCHECKBOX ") { Space = SpaceProcessingModeValues.Preserve });
var run3 = new Run(new FieldChar() { FieldCharType = FieldCharValues.End });
var run4 = new Run(new Text(textAfterTextbox));
var element =
new Paragraph(
run1,
new BookmarkStart() { Name = internalName, Id = new StringValue(internalId.ToString()) },
run2,
run3,
new BookmarkEnd() { Id = new StringValue(internalId.ToString()) },
run4
);
return element;
}
I am filling a listcontrol (Telerik for WinForms) by using the following code :
public static List<RadListDataItem> GetItems()
{
List<RadListDataItem> items = new List<RadListDataItem>();
for (int i = 1; i <= 10; i++)
{
RadListDataItem toadd = new RadListDataItem();
toadd.TextImageRelation = System.Windows.Forms.TextImageRelation.ImageBeforeText;
toadd.Text = "sssssssssss";
//toadd.Image.
string imagename = "MyProject.SuIcons.d" + i + ".JPG";
toadd.Image = new Bitmap(Assembly.GetExecutingAssembly().
GetManifestResourceStream(imagename));
items.Add(toadd);
}
return items;
}
but, only top portition of every item image is show in listcontrol, I mean I cant see the whole image associated with item in the list.
Would you help me please ?
You should set the AutoSizeItems property of the control to true in order to allow the visual items size themselves according to their content:
radListControl1.AutoSizeItems = true;
You can adjust the item size of the radListView. There is a property ItemSize that you can change in the designer view. Or if you want to do it programmatically, you can do something like this.
radListView1.ItemSize = new System.Drawing.Size(200, 400);
The first parameter is the width and the second is the height.
I have a DataTable that is coming from a Web Service, which I need to bind to a ComboBox. I have not grokked doing binding in XAML yet so this question is about binding in code instead. So far I have tried
cboManager.DataContext = Slurp.DistrictManagerSelect().DefaultView;
cboManager.DisplayMemberPath = "Name";
cboManager.SelectedValuePath = "NameListId";
cboManager.SetBinding(ComboBox.ItemsSourceProperty, new Binding());
And I have tried
DataTable tbl = new DataTable();
tbl = Slurp.DistrictManagerSelect();
cboManager.ItemsSource = ((IListSource)tbl).GetList();
cboManager.DisplayMemberPath = "[Name]";
cboManager.SelectedValuePath = "[NameListId]";
DataContext = this;
In both cases I get the list of managers to show but when I select from the ComboBox I get [Name] and [NameListId] and not the values I am expecting. What am I doing wrong (other than not using XAML's DataBinding)?
Edit added after answers to my original post came in.
So (based on Rachel's response) try number three looks like this:
using (DataTable tbl = Slurp.DistrictManagerSelect())
{
List<ManagerList> list = new List<ManagerList>();
foreach (var row in tbl.Rows)
{
list.Add(new ManagerList
{
NameListId = (int)row[0],
Name = row[1].ToString()
});
}
}
Assuming I am doing what she meant the correct way I am no getting this error Cannot apply indexing with [] to an expression of type 'object'
Have you tried to just bind to the DataTable directly? Do you have columns Name and NameListId? Leave off the DataContext (you already assigned the ItemsSource).
DataTable tbl = Slurp.DistrictManagerSelect();
cboManager.ItemsSource = tbl;
cboManager.DisplayMemberPath = "Name";
cboManager.SelectedValuePath = "NameListId";
When you cast to the IListSource I suspect it is combining all the columns. If you want to bind to a list then you need to create items that have properties Name and NameListID.
I think that's because your ItemsSource is a DataTable, so each ComboBoxItem contains a DataContext of a DataRow, and the DataRow class doesn't have properties called Name or NameListId
Basically, you're trying to tell the ComboBox to display DataRow.Name, and set the value to DataRow.NameListId, both of which are not valid properties.
I usually prefer to parse data into objects, and bind the ItemsSource a List<MyObject> or ObservableCollection<MyObject>
foreach(DataRow row in tbl.Rows)
list.Add(new MyObject { Name = row[0].ToString(), NameListId = (int)row[1] });
cboManager.ItemsSource = list;
