CADES signature with Json data in C#

I have below json data I need to apply CAdES-BES Signature with Automatic JSON Canonicalization. Please find my json data below. Helpful link from https://www.example-code.com/Csharp/itida_egypt_cades_bes_json_canonicalization.asp. I follow the steps but still digital signature is not applying. Its returns normal json data.

Get string data Xpath

I need help to get data from the site. I use geckofx in my application. I want it to retrieve text data from the xpath location after loading the page
XPathResult xpathResult = geckoWebBrowser1.Document.EvaluateXPath("/html/body/table[3]/tbody/tr[1]/td[2]/a[1]");
IEnumerable<GeckoNode> foundNodes = xpathResult.GetNodes();
How to download data as text?

It looks like you are struggling to retrieve the text from the GeckoFX objects.
Here are a few calls and operations that should get you started:
//get by XPath
XPathResult xpathResult = _browser.Document.EvaluateXPath("//*[#id]/div/p[2]");
var foundNodes = xpathResult.GetNodes();
foreach (var node in foundNodes)
{
var x = node.TextContent; // get text text contained by this node (including children)
GeckoHtmlElement element = node as GeckoHtmlElement; //cast to access.. inner/outerHtml
string inner = element.InnerHtml;
string outer = element.OuterHtml;
//iterate child nodes
foreach (var child in node.ChildNodes)
{
}
}
//get by id
GeckoHtmlElement htmlElementById = _browser.Document.GetHtmlElementById("mw-content-text");
//get by tag
GeckoElementCollection byTag = _browser.Document.GetElementsByTagName("input");
foreach (var ele in byTag)
{
var y = ele.GetAttribute("value");
}
//get by class
var byClass = _browser.Document.GetElementsByClassName("input");
foreach (var node in byClass)
{
//...
}
//cast to a different object
var username = ((GeckoInputElement)_browser.Document.GetHtmlElementById("yourUsername")).Value;
//create new object from DomObject
var button = new GeckoButtonElement(_browser.Document.GetElementById("myBtn").DomObject);

I also insert the code from which I used a little longer code but it also works. maybe someone will need it. The creator of the code is Đinh Công Thắng, Web Automation App,

Create Pivot Table Filters With EPPLUS

I am using EPPLUS excel library. Do you have an idea how to create pivot table with report filters, row label and values ? Some simple example will be excellent.

Here is a simple example. Note that EEPlus does not have the ability to do page filters so you will have to use (in order of difficulty) VBA, Excel Interop, or XML manipulation (I used XML below). You can put this code into a unit test of the EPPlus source download for easy testing:
const string FORMATCURRENCY = "#,###;[Red](#,###)";
var file = new FileInfo(#"c:\temp\temp.xlsx");
if (file.Exists)
file.Delete();
var pck = new ExcelPackage(file);
var workbook = pck.Workbook;
var worksheet = workbook.Worksheets.Add("newsheet");
//The data
worksheet.Cells["A20"].Value = "Col1";
worksheet.Cells["A21"].Value = "sdf";
worksheet.Cells["A22"].Value = "wer";
worksheet.Cells["A23"].Value = "ghgh";
worksheet.Cells["A24"].Value = "sdf";
worksheet.Cells["A25"].Value = "wer";
worksheet.Cells["A26"].Value = "ghgh";
worksheet.Cells["A27"].Value = "sdf";

Sorry for all the edit but I have been working on this for a little while when I stumbled on this question. I created an extension method just for applying a filter. Give it the field name (it assumes there is a header line contining the column names), the filters you want to apply, and the worksheet containing the data or it will just the Pivot Table worksheet if no data worksheet is passed in. It have done basic testing so you should QA:
public static bool FilterField(this ExcelPivotTable pivotTable, string pageFieldName, IEnumerable<object> filters, ExcelWorksheet dataWorksheet = null)
{
//set the worksheet
var ws = dataWorksheet ?? pivotTable.WorkSheet;
//Set the cache definitions and cache fields
var xdCacheDefinition = pivotTable.CacheDefinition.CacheDefinitionXml;
var xeCacheFields = xdCacheDefinition.FirstChild["cacheFields"];
if (xeCacheFields == null)
return false;
//Go the field list in the definitions, note the field idx and valuesfor
var count = 0;
var fieldIndex = -1;
List<object> fieldValues = null;
foreach (XmlElement cField in xeCacheFields)
{
var att = cField.Attributes["name"];
if (att != null && att.Value.Equals(pageFieldName, StringComparison.OrdinalIgnoreCase))
{
//store the field data
fieldIndex = count;
var dataddress = new ExcelAddress(pivotTable.CacheDefinition.SourceRange.Address);
var valueHeader = ws
.Cells[dataddress.Start.Row, dataddress.Start.Column, dataddress.Start.Row, dataddress.End.Column]
.FirstOrDefault(cell => cell.Value.ToString().Equals(pageFieldName, StringComparison.OrdinalIgnoreCase));
if (valueHeader == null)
return false;
//Get the range minus the header row
var valueObject = valueHeader.Offset(1, 0, dataddress.End.Row - dataddress.Start.Row, 1).Value;
var values = (object[,])valueObject;
fieldValues = values
.Cast<object>()
.Distinct()
.ToList();
//kick back if the types are mixed
if (fieldValues.FirstOrDefault(v => v is string) != null && fieldValues.FirstOrDefault(v => !(v is string)) != null)
throw new NotImplementedException("Filter function does not (yet) support mixed parameter types");
//fill in the shared items for the field
var sharedItems = cField.GetElementsByTagName("sharedItems")[0] as XmlElement;
if (sharedItems == null)
continue;
//Reset the collection attributes
sharedItems.RemoveAllAttributes();
//Handle numerics - assume all or nothing
var isNumeric = fieldValues.FirstOrDefault(v => v is string) == null;
if (isNumeric)
{
att = xdCacheDefinition.CreateAttribute("containsSemiMixedTypes");
att.Value = "0";
sharedItems.Attributes.Append(att);
att = xdCacheDefinition.CreateAttribute("containsString");
att.Value = "0";
sharedItems.Attributes.Append(att);
att = xdCacheDefinition.CreateAttribute("containsNumber");

{
var item = xdCacheDefinition.CreateElement(isNumeric ? "n" : "s", sharedItems.NamespaceURI);
att = xdCacheDefinition.CreateAttribute("v");
att.Value = fieldvalue.ToString();
item.Attributes.Append(att);
sharedItems.AppendChild(item);
}
break;
}
count++;
}
if (fieldIndex == -1 || fieldValues == null)
return false;
//Now go back to the main pivot table xml and add the cross references to complete filtering
var xdPivotTable = pivotTable.PivotTableXml;
var xdPivotFields = xdPivotTable.FirstChild["pivotFields"];
if (xdPivotFields == null)
return false;
var filtervalues = filters.ToList();
count = 0;
foreach (XmlElement pField in xdPivotFields)

att.Value = "default";
defaultitem.Attributes.Append(att);
items.AppendChild(defaultitem);
break;
}
count++;
}
return true;
}
To use it in the above example, you would do something like this:
pivotTable.FilterField("Col2", new List<string> { "Group B" });

Dynamic Report building Refresh() is not changing data

I am trying to View a report dynamically from code behind. But when the parameters are changed from dynamic textboxes added in the page. in the report refresh() the data is not changed.
I call sqlDS() and reportBuild() in the !IsPostback.
This method is for defining the sqlDatasource:
protected void sqlDS()
{
string conString, prName = "";
int counter = 0;
Reporting rep = new Reporting();
rep = rep.searchReport(repID_HF.Value);
Reporting repFold = new Reporting();
repFold = repFold.searchFolder(foldID_HF.Value);
if (repFold.FolderName.Split('(')[1] == "Web Reports)")
{
conString = dbSql.connectionStringAll;
prName = dbSql.providerName;
}
else
{
conString = db.connectionStringAll;
prName = db.providerName;
}
SqlDataSource1.ConnectionString = conString;
SqlDataSource1.ProviderName = prName;
string sqlString = System.IO.File.ReadAllText(Server.MapPath("~/Reports/SQLs/" + rep.SqlFile));
sqlString.Replace(System.Environment.NewLine, " ");
SqlDataSource1.SelectCommand = sqlString;
SqlDataSource1.CancelSelectOnNullParameter = false;
Reporting repParam = new Reporting();
allPs = repParam.getAllParamRep(rep.RepID);
foreach (Reporting itemParam in allPs)
{
if (itemParam.ParamType == "Date")
{
SqlDataSource1.SelectParameters.Add(":" + itemParam.ParamName, itemParam.ParamDefaultValue);
counter++;
}
else if (itemParam.ParamType == "Text")
{
SqlDataSource1.SelectParameters.Add(":" + itemParam.ParamName, itemParam.ParamDefaultValue);
counter++;
}
else if (itemParam.ParamType == "Menu")
{
counter++;
}
}
}
This method is for declaring the report properties:
protected void reportBuild()
{
Reporting rep2 = new Reporting();
rep2 = rep2.searchReport(repID_HF.Value);
ReportViewer1.LocalReport.ReportPath = "Reports/RDLC/" + rep2.RdlcFile;
this.ReportViewer1.LocalReport.ReportEmbeddedResource = rep2.RdlcFile;
ReportParameter[] paramss = new ReportParameter[SqlDataSource1.SelectParameters.Count];
for (int i = 0; i < SqlDataSource1.SelectParameters.Count; i++)
{
paramss[i] = new ReportParameter(SqlDataSource1.SelectParameters[i].Name.Split(':')[1], SqlDataSource1.SelectParameters[i].DefaultValue);
}
ReportDataSource rds = new ReportDataSource(rep2.DatasetName.Split('.')[0], SqlDataSource1);

//paramss[1] = new ReportParameter("CUST_NUM", SqlDataSource1.SelectParameters[1].DefaultValue);
ReportViewer1.LocalReport.SetParameters(paramss);
ReportViewer1.LocalReport.Refresh();
}
In the reportViewer refresh method i try to set the new parameters according to the dynamic textboxes added in the page:
protected void ReportViewer1_ReportRefresh(object sender, System.ComponentModel.CancelEventArgs e)
{
foreach (Control txt in Panel1.Controls)
{
if (txt is TextBox)
{
txts.Add(txt);
}
}
foreach (TextBox txtbox in txts)
{
Reporting repP = new Reporting();
repP = repP.searchParam(txtbox.Attributes["pID"].ToString());
if (repP.ParamType == "Date")
{
SqlDataSource1.SelectParameters[":" + repP.ParamName].DefaultValue = txtbox.Text;
}
else if (repP.ParamType == "Text")
{
SqlDataSource1.SelectParameters[":" + repP.ParamName].DefaultValue = txtbox.Text;
}
}
//Reporting r = new Reporting();
//r = r.searchReport(repID_HF.Value);
//Reporting rep = new Reporting();
//rep = rep.searchReport(repID_HF.Value);
//ReportDataSource rds = new ReportDataSource(rep.DatasetName.Split('.')[0], SqlDataSource1);
//this.ReportViewer1.Reset();
//ReportViewer1.LocalReport.DataSources.Clear();
//ReportViewer1.LocalReport.DataSources.Add(rds);
ReportParameterInfoCollection x = ReportViewer1.LocalReport.GetParameters();
//Response.Redirect(Request.RawUrl);
ReportViewer1.LocalReport.Refresh();
}
I tried debugging and found every thing is working correctly the SQL parameters changed, the Report Parameters also is changed.
so why the data in the report is not changed? Plz help me

I got a better and easier way to solve this problem using this link

And you can use array of strings to pass attributes.

Create A treenode with List

I have a table in this structure
ListA labelName
1 Colorado
1 Wyoming
1 Illinois
2 New York
2 Ohio
I am trying to create a tree where if LISTA = 1, it goes under one node called "header one" and Colorado, Wyoming, Illinois as its Leaf and samething with value "2"... by doing this I am getting 3 "Header one" nodes instead of having all those three nodes under one...
SqlCommand cmd = con.CreateCommand();
comd.CommandText = "SELECT * FROM myTable";
con.Open();
SqlDataReader reader = comd.ExecuteReader();
while (reader.Read())
{
City MyData = new City();
MyData.ListA = reader["ListA"].ToString().Trim();
MyData.labelName = reader["labelName"].ToString().Trim();
giveData.Add(MyData);
}
int count = 1;
List<TreeNode> myNode = new List<TreeNode>();
foreach (City MyData in giveData)
{
// 1st foreach
if (MyData.ListA != "1")
{
TreeNode treeNode = new TreeNode();
treeNode.id = count++;
treeNode.name = "Header One";
treeNode.leaf = false;
List<TreeNode> Level1 = new List<TreeNode>();
foreach (City labelName in giveData)
{
if (labelName.ListA == "1")
{// 2nd foreach
TreeNode node1 = new TreeNode();
node1.id = count++;
node1.name = labelName.labelName;
node1.leaf = true;
Level1.Add(node1);
}
}
treeNode.children = Level1;
myNode.Add(treeNode);
}
else if (MyData.ListA != "2")
{
TreeNode treeNode = new TreeNode();
treeNode.id = count++;
treeNode.name = "Header Two";
treeNode.leaf = false;
List<TreeNode> Level1 = new List<TreeNode>();
foreach (City labelName in giveData)
{
if (labelName.ListA == "2")
{// 2nd foreach
TreeNode node1 = new TreeNode();
node1.id = count++;
node1.name = labelName.labelName;
node1.leaf = true;
Level1.Add(node1);
}
}
treeNode.children = Level1;
myNode.Add(treeNode);
}
}
return JsonConvert.SerializeObject(myNode);
What would be the best way to handle this

What you need to do is group the data on ListA.
var groups = giveData.GroupBy(state => state.ListA);
foreach(var group in groups)
{
//add header to treeview
string header = group.Key;
foreach(var state in group)
{
//add this state as a child of the group you just added
}
}
I'd also suggest creating a lookup to help you map the ListA number to it's textual representation:
var headerLookup = new Dictionary<string, string>()
{
{"1", "Header One"},
{"2", "Header Two"},
{"3", "Header Three"}
};
This will allow you to do the following:
string headerText = headerLookup[group.Key];
