I have an RTB with InlineUIContainer's. I store them in a List, so I can access them directly. How can I remove them from my RTB in C#?
Code example:
// for some TextPointer textPointer in my RTB
TextBlock tb = new TextBlock();
tb.Text = "hello world";
InlineUIContainer inlineUIContainer = new InlineUIContainer(tb, textPointer);
tb_list.Add(inlineUIContainer);
Here, you can remove it like below. If this is your local collection of containers:
List<InlineUIContainer> containers = new List<InlineUIContainer>();
and you want to remove the container which is first in your list then:
InlineUIContainer inlineContainer = containers[0] ;
foreach (var block in myRTB.Document.Blocks)
{
if (block is Paragraph)
{
var paragraph = block as Paragraph;
if (paragraph.Inlines.Contains(inlineContainer))
{
paragraph.Inlines.Remove(inlineContainer);
}
}
}

I'm wondering how I can get the contents of a stackpanel which has been added to a GridViewItem (YouTube data API, the stackpanel contains a bitmap image for a thumbnail, the title of the video and a hidden TextBlock with the video ID for reference).
To clarify, I need to be able to obtain the contents of the StackPanel that is contained in the GridViewItem (such as the string of that hidden TextBox) so I can use the data to display the correct video.
Here's the code I use to create the stackpanel.
public async Task SearchByKeyword(string searchTerm)
{
GeneralFunctions gf = new GeneralFunctions();
var youtubeService = new YouTubeService(new BaseClientService.Initializer()
{
ApiKey = gf.YouTubeAPIKey,
ApplicationName = this.GetType().ToString()
});
var searchListRequest = youtubeService.Search.List("snippet");
searchListRequest.Q = searchTerm; // Replace with your search term.
searchListRequest.MaxResults = 50;
searchListRequest.SafeSearch = SearchResource.ListRequest.SafeSearchEnum.Strict;
// Call the search.list method to retrieve results matching the specified query term.
var searchListResponse = await searchListRequest.ExecuteAsync();
List<string> videos = new List<string>();
List<string> channels = new List<string>();
List<string> playlists = new List<string>();
// Add each result to the appropriate list, and then display the lists of
// matching videos, channels, and playlists.
foreach (var searchResult in searchListResponse.Items)
{
switch (searchResult.Id.Kind)
{
case "youtube#video":
// Create a new StackPanel to insert as a ListViewItem
StackPanel sPanel = new StackPanel();
sPanel.HorizontalAlignment = HorizontalAlignment.Stretch;
sPanel.VerticalAlignment = VerticalAlignment.Stretch;
sPanel.Orientation = Orientation.Vertical;
sPanel.Width = 160;
sPanel.Height = 160;
// Create new StackPanel "Child" elements with alignment and width
TextBlock tb1 = new TextBlock();
tb1.Text = searchResult.Snippet.Title;
tb1.TextWrapping = TextWrapping.WrapWholeWords;
tb1.Width = 160;
// Create new StackPanel "Child" elements with alignment and width
TextBlock tb2 = new TextBlock();
tb2.Text = searchResult.Snippet.ChannelId;
tb2.TextWrapping = TextWrapping.WrapWholeWords;
tb2.Width = 160;
// Create new StackPanel child element for a 120x120 thumbnail of the videos from the search results
Image image = new Image();
image.Source = new BitmapImage(new Uri(searchResult.Snippet.Thumbnails.Default__.Url, UriKind.Absolute));
// Add a "hidden" child element to each stackpanel to hold the video identity
TextBlock h1 = new TextBlock();
h1.Text = searchResult.Id.VideoId.ToString();
h1.Visibility = Visibility.Collapsed;
h1.TextWrapping = TextWrapping.WrapWholeWords;
sPanel.Children.Add(image);
sPanel.Children.Add(tb1);
sPanel.Children.Add(tb2);
sPanel.Children.Add(h1);
SearchResults.Items.Add(sPanel);
break;
case "youtube#channel":
//SearchResults.Items.Add(String.Format("{0} ({1})", searchResult.Snippet.Title, searchResult.Id.ChannelId));
break;
case "youtube#playlist":
//playlists.Add(String.Format("{0} ({1})", searchResult.Snippet.Title, searchResult.Id.PlaylistId));
break;
}
}
//Console.WriteLine(String.Format("Videos:\n{0}\n", string.Join("\n", videos)));
//Console.WriteLine(String.Format("Channels:\n{0}\n", string.Join("\n", channels)));
//Console.WriteLine(String.Format("Playlists:\n{0}\n", string.Join("\n", playlists)));
}
Any help is appreciated.
Thanks
I guess I should never code tired right? The answer to my own question is actually very very simple
if (SearchResults.SelectedItems.Count > 0)
{
StackPanel sp = (StackPanel)SearchResults.SelectedItem;
TextBlock tb1 = (TextBlock)sp.Children[1];
TextBlock tb2 = (TextBlock)sp.Children[2];
TextBlock hf1 = (TextBlock)sp.Children[3];
}
I'm dynamically updating a ListView like that:
ListViewItem item = new ListViewItem();
item.Text = "Text1";
item.SubItems.Add("Text2");
item.SubItems.Add("Text3");
item.SubItems.Add("Text4");
item.Tag = i;
listView.Items.Add(item);
now I want that instead of Text4 will be a lil icon I will get dynamically from a url. I read a lot of threads and tried many things - but I can't get this to work..
You need to implement ImageList in your function.
Code :
// get picture resource
WebClient _web = new WebClient();
byte[] _data = _wb.DownloadData("http://www.myzony.com/usr/uploads/2017/03/3197402477.png");
MemoryStream _ms = new MemoryStream(_data);
// Loaded to imagelist
ImageList list = new ImageList();
list.Images.Add("pic1",Image.FromStream(_ms));
// bind listview
listView1.SmallImageList = list;
ListViewItem _item1 = new ListViewItem();
_item1.Text = "Test";
_item1.SubItems.Add("Test2");
_item1.SubItems.Add("pic1");
_item1.ImageKey = "pic1";
listView1.Items.Add(_item1);

I'm trying to generate Word documents using OpenXML SDK and Word Document Generator. I need to apply my custom style on ContentControls (Repeating Section).
For Recursive Placeholders, I use
foreach (var item in list)
{
var datacontext = new OpenXmlElementDataContext()
{
Element = openXmlElementDataContext.Element,
DataContext = item.Value
};
var clonedElement = CloneElementAndSetContentInPlaceholders(datacontext);
SetContentOfContentControl(clonedElement, item.Value);
}
openXmlElementDataContext.Element.Remove();
I need to apply my style on this element. How to I can do ?
I try to see generated code with "Open XML SDK 2.5 Productivity Tool for Microsoft Office" to inspire me:
var moduleDatacontext = new OpenXmlElementDataContext()
{
Element = openXmlElementDataContext.Element,
DataContext = module.Valeur
};
var moduleClonedElement = CloneElementAndSetContentInPlaceholders(moduleDatacontext);
var sdtProperties1 = new SdtProperties();
var styleId1 = new StyleId() { Val = "FormationTitre2" };
ParagraphMarkRunProperties paragraphMarkRunProperties1 = new ParagraphMarkRunProperties();
RunFonts runFonts1 = new RunFonts() { ComplexScriptTheme = ThemeFontValues.MinorHighAnsi };
paragraphMarkRunProperties1.Append(runFonts1);
sdtProperties1.Append(styleId1);
sdtProperties1.Append(paragraphMarkRunProperties1);
Run run1 = new Run() { RsidRunProperties = "00C463E5" };
RunProperties runProperties1 = new RunProperties();
RunFonts runFonts2 = new RunFonts() { ComplexScriptTheme = ThemeFontValues.MinorHighAnsi };
runProperties1.Append(runFonts2);
run1.Append(runProperties1);
moduleClonedElement.Append(sdtProperties1);
moduleClonedElement.Append(run1);
When I open the generated document, I have this error :
We're sorry. We can't open "...docx" because we found a problem with its contents.
I validate the document and I can see 15 errors:
Full Size
I've found the solution. I search first paragraph and apply my custom style on it.
// clone element
var clonedElement = CloneElementAndSetContentInPlaceholders(datacontext);
// search the first created paragraph on my clonedElement
Paragraph p = clonedElement.Descendants<Paragraph>().FirstOrDefault();
if (p != null)
p.PrependChild<ParagraphProperties>(new ParagraphProperties());
// get the paragraph properties
ParagraphProperties pPr = p.Elements<ParagraphProperties>().First();
// apply style
pPr.ParagraphStyleId = new ParagraphStyleId { Val = "FormationTitre2" };
// set content of content control
SetContentOfContentControl(clonedElement, item.Value);
I would like to have string containing Inline markups like
var str = "foo bar <Bold>dong</Bold>"
and feed TextBlock with it so the text would get formatted like it would be added to Inlines collection. How could I achive that?
You could wrap the text with a <TextBlock> tag and parse the whole thing as XAML:
public TextBlock CreateTextBlock(string inlines)
{
var xaml = "<TextBlock xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">"
+ inlines + "</TextBlock>";
return XamlReader.Parse(xaml) as TextBlock;
}
Then use the newly created TextBlock as you like. Put it in some Panel
var str = "foo bar <Bold>dong</Bold>";
grid.Children.Add(CreateTextBlock(str));
or perhaps copy its Inlines to another TextBlock.
You can try the below code.
<TextBlock x:Name="txtBlock"/>
string regexStr = #"<S>(?<Str>.*?)</S>|<B>(?<Bold>.*?)</B>";
var str = "<S>foo bar </S><B>dong</B>";
Regex regx = new Regex(regexStr);
Match match = regx.Match(str);
Run inline = null;
while (match.Success)
{
if (!string.IsNullOrEmpty(match.Groups["Str"].Value))
{
inline = new Run(match.Groups["Str"].Value);
txtBlock.Inlines.Add(inline);
}
else if (!string.IsNullOrEmpty(match.Groups["Bold"].Value))
{
inline = new Run(match.Groups["Bold"].Value);
inline.FontWeight = FontWeights.Bold;
txtBlock.Inlines.Add(inline);
}
match = match.NextMatch();
}
Is there a way to order stackpanels based on some of its child elements?
In the code behind I add some generic things like groupbox and textblock to a stackpanel, one of the textblocks information is DateTime from my webservice, I have tryed sorting via descending order using linq but the output is still the same.
So I was wondering if its possible to sort by one of the stackpanels child elements namely the textblock1.Text that holds the DateTime attribute?
XDocument xDoc = XDocument.Load(uriGroups);
var sortedXdoc = xDoc.Descendants("Student")
.OrderByDescending(x => Convert.ToDateTime(x.Element("TimeAdded").Value));
foreach (var node in xDoc.Descendants("Student"))
{
GroupBox groupbox = new GroupBox();
groupbox.Header = String.Format(node.Element("StudentID").Value);
groupbox.Width = 100;
groupbox.Height = 100;
groupbox.Margin = new Thickness(1);
TextBlock textBlock = new TextBlock();
textBlock.Text = String.Format(node.Element("FirstName").Value + " " + (node.Element("LastName").Value));
textBlock.TextAlignment = TextAlignment.Center;
TextBlock textBlock1 = new TextBlock();
textBlock1.Text = (DateTime.Parse(node.Element("TimeAdded").Value)).ToString("d");
String.Format("{0:d/M/yyyy}", DateTime.Parse(node.Element("TimeAdded").Value));
textBlock1.TextAlignment = TextAlignment.Center;
textBlock1.VerticalAlignment = VerticalAlignment.Bottom;
StackPanel stackPanel = new StackPanel();
stackPanel.Children.Add(groupbox);
stackPanel.Children.Add(textBlock);
stackPanel.Children.Add(textBlock1);
stackPanel.Margin = new Thickness(5);
stackPanel.MouseEnter += new MouseEventHandler(stackpanel_MouseEnter);
stackPanel.MouseLeave += new MouseEventHandler(stackpanel_MouseLeave);
MainArea1.Children.Add(stackPanel);
}
}
The order of display is totally defined by the order of calls to
MainArea1.Children.Add(stackPanel);
So, try something like
foreach (var node in xDoc.Descendants("Student").OrderBy(e => ...))
{
....
}
(And you really should be using Temlates here)
