I have a groupbox that contains a listbox that displays a bunch of .txt files.
Also in this groupbox is a textbox that I would like to use to search the list of files. I have added some code to my textbox textchange event, but all it does is clear my listbox, and on backspace the listbox is not repopulating with the .txt files it displays? ant help would be greatly apreciated, thanx
private void custsearchbox_TextChanged(object sender, EventArgs e)
{
var itemList = custList.Items.Cast<string>().ToList();
if (itemList.Count > 0)
{
//clear the items from the list
custList.Items.Clear();
//filter the items and add them to the list
custList.Items.AddRange(
itemList.Where(i => i.Contains(custsearchbox.Text)).ToArray());
}
}
this works:
listsup.Items.Clear();
Supfile = System.AppDomain.CurrentDomain.BaseDirectory + "data\\Suppliers.txt";
List<string> proName = new List<string>();
using (StreamReader rdr = new StreamReader(Supfile))
{
string line;
while ((line = rdr.ReadLine()) != null)
{
if (line.ToString().ToLower().Contains(supsearchtxt.Text))
{
string[] val = line.Split(',');
listsup.Items.Add(val[0]);
}
}
}

On the Page, I add UserControl into GridView dynamically. So, each UserControl can contain different kind of controls ( TextBox, CheckBox, Radio Button)
say , the name of UserControl is : UserForm.
problem :
How to get a collection of control using VisualTreeHelper and check if textBox is empty.
I found a code similiar to this problem and modified it but not working.
I dont know what this means and if this is required?
list.AddRange(AllTextBoxes(child))
Should I use MyList.Select() or MyList.Where() ?
void FindTextBoxes()
{
List <TextBox> MyList = AllTextBoxes(UserForm);
var count = MyList.Where(x= > if(string.IsEmptyOrNull(x.Text));
}
List <TextBox> AllTextBoxes(DependencyObject parent)
{
var list = new List <TextBox>();
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++)
{
var child = VisualTreeHelper.GetChild(parent, i);
if (child is TextBox)
list.Add(child as TextBox);
list.AddRange(AllTextBoxes(child));
}
return list;
}
Here's what I use.
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
var textBoxes = AllChildren(MyGridView).Where(x => x is TextBox);
}
public IEnumerable<Control> AllChildren(DependencyObject parent)
{
for (int index = 0; index < VisualTreeHelper.GetChildrenCount(parent); index++)
{
var child = VisualTreeHelper.GetChild(parent, index);
if (child is Control)
yield return child as Control;
foreach (var item in AllChildren(child))
yield return item;
}
}
Best of luck!
Today This is the demo to show data from CSV for DAT file without make custom class on tableView in JavaFX 2.0. I call this TableView as Dynamic TableView because the tableview automatically manages the columns and rows.
On my research about the editable on tableView we must have a custom class and implement it to tableView to show as this demo ==> http://docs.oracle.com/javafx/2/ui_controls/table-view.htm
But in this case I can not do it because we don't know how many column example with csv file or .dat file.... I want to do editable on this tableView in this case by add TextField into TableCell. How does it do without make custom class (because you do not how many column ...), and if it must make custom class then how about the design of custom class for this case?
Could you please help me?
private void getDataDetailWithDynamic() {
tblView.getItems().clear();
tblView.getColumns().clear();
tblView.setPlaceholder(new Label("Loading..."));
// #Override
try {
File aFile = new File(txtFilePath.getText());
InputStream is = new BufferedInputStream(new FileInputStream(aFile));
Reader reader = new InputStreamReader(is, "UTF-8");
BufferedReader in = new BufferedReader(reader);
final String headerLine = in.readLine();
final String[] headerValues = headerLine.split("\t");
for (int column = 0; column < headerValues.length; column++) {
tblView.getColumns().add(
createColumn(column, headerValues[column]));
}
// Data:
String dataLine;
while ((dataLine = in.readLine()) != null) {
final String[] dataValues = dataLine.split("\t");
// Add additional columns if necessary:
for (int columnIndex = tblView.getColumns().size(); columnIndex < dataValues.length; columnIndex++) {
tblView.getColumns().add(createColumn(columnIndex, ""));
}
// Add data to table:
ObservableList<StringProperty> data = FXCollections
.observableArrayList();
for (String value : dataValues) {
data.add(new SimpleStringProperty(value));
}
tblView.getItems().add(data);
}
} catch (Exception ex) {
System.out.println("ex: " + ex.toString());
}
for(int i=0; i<tblView.getColumns().size(); i++) {
TableColumn col = (TableColumn)tblView.getColumns().get(i);
col.setPrefWidth(70);
}
}
private TableColumn createColumn(
final int columnIndex, String columnTitle) {
TableColumn column = new TableColumn(DefaultVars.BLANK_CHARACTER);
String title;
if (columnTitle == null || columnTitle.trim().length() == 0) {
title = "Column " + (columnIndex + 1);
} else {
title = columnTitle;
}
Callback<TableColumn, TableCell> cellFactory = new Callback<TableColumn, TableCell>() {
#Override
public TableCell call(TableColumn p) {
System.out.println("event cell");
EditingCellData cellExtend = new EditingCellData();
return cellExtend;
}
};
column.setText(title);
column.setCellValueFactory(cellFactory);
return column;
}

I want to Collect the usernames added in the PeoplePicker and display them in the textbox on the click of "Add" button for a custom aspx page.
I tried many codes but its not working.
Here is my code:
protected void btnpicker_Click(object sender, EventArgs e)
{
for (int i = 0; i < userPicker.ResolvedEntities.Count; i++)
{
PickerEntity picker = (PickerEntity)userPicker.ResolvedEntities[i];
Hashtable hstEntityData = picker.EntityData;
string accountName = Convert.ToString(hstEntityData["AccountName"]);
txtPicker.Text = "Count" + hstEntityData.Count.ToString();
txtPicker.TextMode = TextBoxMode.MultiLine;
}
}
Help Highly Appreciated.
Try the following code.
protected void btnpicker_Click(object sender, EventArgs e)
{
for (int i = 0; i < userPicker.ResolvedEntities.Count; i++)
{
PickerEntity picker = (PickerEntity)userPicker.ResolvedEntities[i];
yourTextBox.Text = "Count: " + new SPFieldUserValue(yourSPWebObject, Convert.ToInt32(picker.EntityData["SPUserID"]), picker.Key).User.Name;
}
}
This code will give all name of the users in your textbox.

Treat the CSV file like an excel workbook and you will find a lot of examples on the web for what you need to do.
ExcelFile ef = new ExcelFile();
// Loads file.
ef.LoadCsv("filename.csv");
// Selects first worksheet.
ExcelWorksheet ws = ef.Worksheets[0];
I won't go into details, but you can read lines text from a file with File.ReadAllLines.
Once you have those lines, you can split them into parts using String.Split (at least this will work if the CSV file contains very simple information as in your example).
I have a fillable PDF contains CheckBoxes and RadioButtons and TextBox.
How do i get the CheckBox Name and its value also how do we know that it is a checkbox / Radio Button?
i'm using iTextSharp and have look at my below code
PdfReader pdfReader = new PdfReader(FileName);
pdfReader.SelectPages("37");
MemoryStream oStream = new MemoryStream();
PdfStamper stamper = new PdfStamper(pdfReader, oStream);
AcroFields form = stamper.AcroFields;
if (form.Fields.Count() > 0)
{
IDictionary<string,AcroFields.Item> oDic= form.Fields;
foreach (string FieldName in oDic.Keys)
{
//FieldName - CheckBox name; i need to confirm that is a Checkbox...
}
foreach (AcroFields.Item oItem in oDic.Values)
{
// how do we get check box values
}
}
The following code may help you out, if you still need it. It only works for AcroForms
int BUTTON = 1;
int CHECK_BOX = 2;
int RADIO_BUTTON = 3;
int TEXT_FIELD = 4;
int LIST_BOX = 5;
int COMBO_BOX = 6;
PdfReader pdfReader = new PdfReader(path);
AcroFields af = pdfReader.AcroFields;
foreach (var field in af.Fields)
{
bool isRadio = RADIO_BUTTON == af.GetFieldType(field.Key));
}
Edit:
Also, field.Key is the name of the field and field.Value is the value at it.
For checkboxes, if(field.Value == "Yes") then it is selected... if it is anything else, it is not selected.
Edit:
And I just found how tro get Radio Button options, if you are needing them.
myKey k = new myKey(field.Key, af.GetField(field.Key), af.GetFieldType(field.Key));
if (k.isRadio())
{
try { k.options.AddRange(af.GetAppearanceStates(k.key)); }
catch { }
}
Keys.Add(k);
Radio buttons, checkbox and buttons are all actually the same type of field but with different flags set. You can see the flags in the PDF Spec section 12.7.4.2.1 Table 226.
int ffRadio = 1 << 15; //Per spec, 16th bit is radio button
int ffPushbutton = 1 << 16; //17th bit is push button
For a given Field you want to get the Widgets associated with it. Usually this is just one but can be more so you should account for this.
PdfDictionary w = f.Value.GetWidget(0);
Button fields will have their field type (/Ft) set to /Btn so check for that
if (!w.Contains(PdfName.FT) || !w.Get(PdfName.FT).Equals(PdfName.BTN)) {continue;/*Skipping non-buttons*/ }
For the current Widget get the optional field flags (/Ff) value or use zero if it doesn't exist.
int ff = (w.Contains(PdfName.FF) ? w.GetAsNumber(PdfName.FF).IntValue : 0);
Then just some simple math:
if ((ff & ffRadio) == ffRadio) {
//Is Radio
} else if (((ff & ffRadio) != ffRadio) && ((ff & ffPushbutton) != ffPushbutton)) {
//Is Checkbox
} else {
//Regular button
}
Below is a full-working C# WinForm 2011 app targeting iTextSharp 5.2.0 that shows off all of the above looking at a file called Test.pdf living on your desktop. Just add some logic to the conditionals to handle each button type.
using System;
using System.IO;
using System.Windows.Forms;
using iTextSharp.text.pdf;
namespace WindowsFormsApplication3 {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Test.pdf");
PdfReader reader = new PdfReader(testFile);
var fields = reader.AcroFields;
int ffRadio = 1 << 15; //Per spec, 16th bit is radio button
int ffPushbutton = 1 << 16; //17th bit is push button
int ff;
//Loop through each field
foreach (var f in fields.Fields) {
//Get the widgets for the field (note, this could return more than 1, this should be checked)
PdfDictionary w = f.Value.GetWidget(0);
//See if it is a button-like object (/Ft == /Btn)
if (!w.Contains(PdfName.FT) || !w.Get(PdfName.FT).Equals(PdfName.BTN)) { continue;/*Skipping non-buttons*/ }
//Get the optional field flags, if they don't exist then just use zero
ff = (w.Contains(PdfName.FF) ? w.GetAsNumber(PdfName.FF).IntValue : 0);
if ((ff & ffRadio) == ffRadio) {
//Is Radio
} else if (((ff & ffRadio) != ffRadio) && ((ff & ffPushbutton) != ffPushbutton)) {
//Is Checkbox
} else {
//Regular button
}
}
this.Close();
}
}
}
