I have never worked with xslt before, now i want to add a dropdownlist to the page and need to create a search for the selected value from the repeated items in the page body.
My questions are:
how can i create a dropdownlist in xslt.
i have tried the below links but it didn't work for me.
Generate dynamic dropdown in xslt using c#
how to create a event that will search from repeated items. is there any way by which i can call the dropdown's selectedindex change event.?
please help.


A DropDownList you can create like
<asp:DropDownList xmlns:asp="System.Web.UI.WebControls" ID="TheDdl" OnSelectedIndexChanged="Selection_Change" runat="server">
<asp:ListItem Value="1" Text="Text 1" />
<asp:ListItem Value="2" Text="Text 2" />
<asp:ListItem Value="3" Text="Text 3" />
</asp:DropDownList>
The Code behind Looks like
void Selection_Change(Object sender, EventArgs e)
{
// do something ...
}


Xslt just transforms some source XML into some formatted text, usually HTML or XML. This xslt of yours is creating html code, some < div class="offers_section">. I see there's some links being bound inside the xslt code.
This html code being generated is stored inside the string XSLTOutput.ToString(), which is later inserted into the ASP page as a literal control. The code behind is creating the source XML document XDocOffers by retrieving some data from a database.
You could edit the xslt code which has been provided and to allow it to insert html controls < select> and < option>, instead of going for the asp's < asp:dropdownlist>.
If you want to use some < asp:dropdownlist> control, I guess you're trying to use XDocOffers as the source of data. If not you'd have to do your own code to query from the database.
You can run the code and watch XDocOffers XML document, its structure. Then you can ask specifically which is the member you want to use as the dropdown key, and which as the dropdown value. And get specifically into the matter of the dropdown control.

C# SQL Update Query with multiple symbols

I'm creating a piece of software that should let me update a value in an SQLite DB.
The problem is, this value contains a lot symbols (originally an xml AS value).
I've tried refractor this but I'm just not able to. Is there a faster way to do so maybe?
Thank you in advance!

XSLT in a loop keep getting only first file transformation in the output. How to Stop caching XSLT output

When I am looping thru list of files and doing transformation on each file in a folder the effect of the transformation is as if it keeps transforming first file again and again. The transformation looked to be caching.
Here is the Code for transformation:
I am doing this inside WebAPI call.. in .NET framework 4.5.2 version . The ASP.NET page is calling the WebAPI.
I tried all different overloads and moving instancing transformation new out of loop on the top. I did not find any easy way of disabling the caching.
var d = new DirectoryInfo(strXMLFolder);
foreach (FileInfo file in d.GetFiles())
{
String strXSLTFile = strParamArr[2];
String xmlFile = file.Name;
//File.WriteAllBytes(strFile, transferObj.XSLTTemplateFileData);
XslCompiledTransform proc = new XslCompiledTransform();
proc.Load(strXSLTFolder + strXSLTFile);
proc.Transform(strXMLFolder + xmlFile, strXMLFolder + xmlFile + "-IntermediateXML.xml");
..................................
The XSLT file has following Code:
<data>
<xsl:for-each select="//QuantitativeResponseAssay/Setup/Elements/*/Name">
<row>
<PLA_file_name>
<xsl:value-of select="$vFileName"/>
</PLA_file_name>

Problem is:
Now display the detail in some different format for alternate row. currently, every offer has image in left side and description in right, for alternate row now i want to display description in left and image in right, i have never used xslt file before, can anyone please help... or suggest me how can achieve this.
waiting for your helpful answers..

i have solved out this problem..
Here is the solution, we didn't need to changes anything in c# code(code behind), we have just changed the xslt file t do this, as xslt file number of inbuilt functions to do.
I have used mod as below:
<xsl:for-each select=". | following-sibling::Offer[(position()) < $OffersPerPage]" >
<xsl:choose>
<xsl:when test="position() mod 2 = 1">
data 1
</xsl:when>
<xsl:otherwise>
data 2
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
That's all.....

C# FlowDocument to HTML conversion

Basically, I have a RichTextBox and I want to convert the formatted contents of it to HTML so it can be sent as an email.
The method I am currently using does not give any formatting at all:
string message = new TextRange(messageTextBox.Document.ContentStart,
messageTextBox.Document.ContentEnd).Text;
So I searched around and found this, however, it is over 5 years old and in the comments an MSFT user has commented saying that it is no longer supported - "This sample has been removed from our sample set and is no longer supported", and the HTML it generates is in an older format than modern HTML or XHTML which would be better to have.
Can anybody show me how I can convert the formatted contents of a RichTextBox to HTML?
(So when the email is sent it the recipient sees the email with formatting)

The general technique is to use a XamlWriter to convert the FlowDocument content to a stream of XML, and then to use an XSLT transform to convert the XML to HTML. That's not much of an answer, but that's because there's a huge range of possible HTML representations of any given FlowDocument.
This transform, for instance, converts every top-level Section to a div, every Paragraph to a p, and every Run to a span whose class tells you whether or not it's italicized, bold-faced, or underlined, or any combination of the above. It was useful for the purpose I wrote it for, but to call it a lossy transformation is an understatement:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

exclude-result-prefixes="msxsl x">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="x:Section[not(parent::x:Section)]">
<div>
<xsl:apply-templates select="node()"/>
</div>
</xsl:template>
<xsl:template match="x:Section">
<xsl:apply-templates select="node()"/>
</xsl:template>
<xsl:template match="x:Paragraph">
<p>
<xsl:apply-templates select="node()"/>
</p>
</xsl:template>
<xsl:template match="x:Run">
<xsl:variable name="class">
<xsl:if test="#FontStyle='Italic'">
<xsl:text>i </xsl:text>
</xsl:if>
<xsl:if test="#FontWeight='Bold'">
<xsl:text>b </xsl:text>
</xsl:if>
<xsl:if test="contains(#TextDecorations, 'Underline')">
<xsl:text>u </xsl:text>
</xsl:if>
</xsl:variable>
<span>
<xsl:if test="normalize-space($class) != ''">
<xsl:attribute name="class">
<xsl:value-of select="normalize-space($class)"/>
</xsl:attribute>
</xsl:if>
<xsl:value-of select="text()"/>
</span>
</xsl:template>
</xsl:stylesheet>
Here's a value converter I wrote to do the conversion - note that in order to use the value converter, you also have to hack around and implement a version of RichTextBox that exposes the content as a dependency property. Really this whole project was a pain.
public class FlowDocumentToHtmlConverter : IValueConverter
{
private static XslCompiledTransform ToHtmlTransform;
private static XslCompiledTransform ToXamlTransform;
public FlowDocumentToHtmlConverter()
{
if (ToHtmlTransform == null)
{
ToHtmlTransform = LoadTransformResource("Converters/FlowDocumentToXhtml.xslt");
}
if (ToXamlTransform == null)
{
ToXamlTransform = LoadTransformResource("Converters/XhtmlToFlowDocument.xslt");
}
}
private static XslCompiledTransform LoadTransformResource(string path)
{
Uri uri = new Uri(path, UriKind.Relative);
XmlReader xr = XmlReader.Create(Application.GetResourceStream(uri).Stream);
XslCompiledTransform xslt = new XslCompiledTransform();
xslt.Load(xr);
return xslt;
}

}

throw new InvalidOperationException(

}
FlowDocument d = (FlowDocument)value;
using (MemoryStream ms = new MemoryStream())

using (StringWriter sw = new StringWriter(sb))
{
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
XmlReader xr = XmlReader.Create(ms);
XmlWriter xw = XmlWriter.Create(sw, xws);
ToHtmlTransform.Transform(xr, xw);
}
return sb.ToString();
}

For those who is looking for solution for .Net Core (APS.Net Core) - nuget MarkupConverter did the trick for me. Add dependency reference
<PackageReference Include="MarkupConverter" Version="1.0.6" />
Then use it
MarkupConverter.MarkupConverter markupConverter = new MarkupConverter.MarkupConverter();
try
{
message = markupConverter.ConvertXamlToHtml(message);
}
catch (Exception ex)
{
_logger.LogError(ex, $"Failed to parse flowdocument");
}

Your XML document is not well formed. You have more than one document (root) element. For example:
<a>some</a>
<a>thing</a>
is not well formed. Whereas:
<list>
<a>some</a>
<a>thing</a>
</list>
is well formed.
