How to change text of a cell at runtime in XtraReport?
I am using "DevExpress v2011 vol 1".
I have a few cells and I can change their text one by one using PreviewClick event as below.
private void _cell_PreviewClick(object sender, PreviewMouseEventArgs e)
{
e.Brick.Text = "aaabbbccc"; e.PreviewControl.Refresh();
}
But, in that event I need to change text of other cells simultaneously. I tried below and got no luck
private void _cell_PreviewClick(object sender, PreviewMouseEventArgs e)
{
e.Brick.Text = "aaabbbcc";
otherCell1.Text = "rrrttcwwww"
e.PreviewControl.Refresh();
}

You can handle the DataSourceRowChanged event of the XtraReport Class
private void rpt_DataSourceRowChanged(object sender, DataSourceRowEventArgs e)
{
MyClass xx = bidingSource[e.CurrentRow] as MyClass ;
if (string.IsNullOrWhiteSpace(xx.WorkDescription))
{
xrTableCell25.Visible = false;
xrTableRow3.Visible = false;
xrTableCell25.Text = "456";
}
else
{
xrTableCell25.Visible = true;
xrTableRow3.Visible = true;
xrTableCell25.Text = "123";
}
}

I'm trying to load information with worker and using reportprogress to update progress bar until finshing, but the worker stop working and doesn't finish the for loop or continue after several minutes. I don't know what's the problem and I tried every post here I can find related to this problem and didn't get anything. I hope I can finally get an answer posting my problem here.
Here's the relevant code:
public class Class1
{
public BackgroundWorker unit_read_data_setting_Worker;
public Class1()
{
unit_read_data_setting_Worker = new BackgroundWorker();
unit_read_data_setting_Worker.WorkerReportsProgress = true;
unit_read_data_setting_Worker.WorkerSupportsCancellation = false;
unit_read_data_setting_Worker.DoWork += new DoWorkEventHandler(unit_read_data_setting);
unit_read_data_setting_Worker.ProgressChanged += new ProgressChangedEventHandler(_update_progress);
unit_read_data_setting_Worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(Completed);
}
public void unit_read_data_setting(object sender = null, DoWorkEventArgs e = null)
{
lock (FamilyTreeViewModel.Lock_ParameterList)
{
ObservableCollection<Parameter_UC_ViewModel> _internal_parameter_list =
FamilyTreeViewModel.GetInstance.ParameterList;
if (FamilyTreeViewModel.GetInstance.SelectedUnitSetting != null)
{
if (_internal_parameter_list.Count > 0)
{
for (int i = 0; i < _internal_parameter_list.Count; i++)
{
int startValue = i * 100 / _internal_parameter_list.Count;
unit_read_data_setting_Worker.ReportProgress(startValue);
// do stuff related to the index
// when progress_bar at 76 value, the loop stoppes and cotinue after a minute
}
}
}
}
}
private void _update_progress(object sender, ProgressChangedEventArgs e)
{
FamilyTreeViewModel.GetInstance.Unit_read_data_setting_progress_bar = e.ProgressPercentage;
}
private void Completed(object sender, RunWorkerCompletedEventArgs e)
{
// never gets here but there's no error
}
}
I have two DateTimePickers one as Start Time and other one as end time.
I also have a text box that has duration.
I would like to know how can I add the duration to start time datetimePicker to automatically get the end time in the endTime dateTimePicker?
Though I believe your Service Duration is a combobox, I've still used textbox as per your question.
Call textchanged. When text in textbox changes, the time is added to dateTimePicker2
private void textBox1_TextChanged(object sender, EventArgs e)
{
int mins = Convert.ToInt32(textBox1.Text);
dateTimePicker2.Value = dateTimePicker1.Value.AddMinutes(mins);
}
For combobox, call textchanged as well.
private void comboBox1_TextChanged(object sender, EventArgs e)
{
if (comboBox1.SelectedIndex == -1 || comboBox1.Text == null)
{
dateTimePicker2.Value = dateTimePicker1.Value;
}
else if (comboBox1.Text == "15")
{
dateTimePicker2.Value = dateTimePicker1.Value.AddMinutes(15);
}
else if (comboBox1.Text == "30")
{
dateTimePicker2.Value = dateTimePicker1.Value.AddMinutes(30);
}
else if (comboBox1.Text == "60")
{
dateTimePicker2.Value = dateTimePicker1.Value.AddMinutes(60);
}
}
A newbie, please excuse the terms and explanation.
I have a program that accepts arguments which are in seconds. This in turn runs a timer that shows on the form. I want to give the user the ability to pause the timer for a set amount of time. I am having difficulty in trying to add time after the user Clicks the button as the method that runs the timer and countdown I have a method that gets the parameters of the argument.
I would like to maybe just get the parameters/arguments globally and then use them in all the different methods or threads. I am trying to do this in c# and wpf.
Code below:
public partial class MainWindow : Window
{
//int TimeOutPeriod = Int32.Parse("3600");
//private Timer timer;
System.Timers.Timer timer = new System.Timers.Timer();
public MainWindow()
{
InitializeComponent();
//timer = new Timer(1000);
timer = new System.Timers.Timer(1000);
timer.Elapsed += new ElapsedEventHandler(timer_Elapsed);
timer.Start();
string[] param = Environment.GetCommandLineArgs();
int TimeOutPeriod = Int32.Parse(param[1]);
ProgressBar1.Maximum = TimeOutPeriod;
}
void timer_Elapsed(object sender, ElapsedEventArgs e)
{
string [] param = Environment.GetCommandLineArgs();
int TimeOutPeriod = Int32.Parse(param[1]);
int InYourFaceDisplay = Int32.Parse(param[2]);
this.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, (Action)(() =>
{
if (ProgressBar1.Value < TimeOutPeriod)
{
ProgressBar1.Value += 1;
RebootCDown.Content = "Machine will reboot in : " + (TimeOutPeriod - ProgressBar1.Value) + " Secs";
if ((TimeOutPeriod - ProgressBar1.Value) < InYourFaceDisplay)
{
this.Activate();
}
}
else
{
ShutDownWindows("0");
timer.Stop();
this.Close();
}
}));
}
private void SnoozeNow_Click(object sender, RoutedEventArgs e)
{
WindowState = WindowState.Minimized;
System.Windows.Forms.NotifyIcon ni = new System.Windows.Forms.NotifyIcon();
ShowInTaskbar = false;
ni.Icon = new System.Drawing.Icon("C:\\temp\\RebootIco.ico");
ni.Visible = true;
ShowInTaskbar = false;
ni.ShowBalloonTip(5000, "Test App", "Notify icon is working! Right click to access the context menu.", System.Windows.Forms.ToolTipIcon.Info);
Task.Delay(10000);
ShowInTaskbar = true;
}
}
I am using PagedDataSource To Paginate Repeater and it works fine but is there a way to highlight selected page number or make it bold. I tried css, itemcommand,and click event but no luck.
Thanks in advance
Repeater:
<asp:Repeater ID="repeaterPager" runat="server" OnItemCommand="repeaterPager_ItemCommand">
<ItemTemplate>
<asp:LinkButton CssClass="sayfaNo" ID="btnPage" CommandName="Page" CommandArgument="<%#Container.DataItem %>" runat="server">
<%# Container.DataItem %></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>

private void MakeleleriGetir()
{
SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings[0].ConnectionString);
SqlDataAdapter da = new SqlDataAdapter("SELECT p.PostID,p.Title,p.DateTime,p.PostShort,p.CategoryID,i.SmallFileName,c.CategoryName From Posts as p inner join Resimler as i ON p.PostID = i.PostID inner join Categories as c On p.CategoryID = c.CategoryID", cnn);
DataTable dt = new DataTable();
da.Fill(dt);
PagedDataSource pds = new PagedDataSource();
pds.DataSource = dt.DefaultView;
pds.AllowPaging = true;
pds.PageSize = 4;
pds.CurrentPageIndex = CurrentPage;
PageCount = pds.PageCount;
btnPrevious.Enabled = !pds.IsFirstPage;
btnNext.Enabled = !pds.IsLastPage;
if (pds.PageCount > 1)
{
repeaterPager.Visible = true;
ArrayList pages = new ArrayList();
for (int i = 0; i < pds.PageCount; i++)
{
{
pages.Add((i + 1).ToString());
}
}
repeaterPager.DataSource = pages;
repeaterPager.DataBind();
}

}
RepeaterPosts.DataSource = pds;
RepeaterPosts.DataBind();
}
protected int CurrentPage
{
get
{ // look for current page in ViewState
object o = this.ViewState["_CurrentPage"];
if (o == null)
{
return 0; // default to showing the first page
}
else
{
return (int)o;
}
}
set
{
this.ViewState["_CurrentPage"] = value;
}
}
public int PageCount
{
get
{
if (ViewState["_PageCount"] != null)
return Convert.ToInt32(ViewState["_PageCount"]);
else
return 0;
}
set
{
ViewState["_PageCount"] = value;
}
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
repeaterPager.ItemCommand += new RepeaterCommandEventHandler(repeaterPager_ItemCommand);
}
protected void repeaterPager_ItemCommand(object source, RepeaterCommandEventArgs e)
{
CurrentPage = Convert.ToInt32(e.CommandArgument) - 1;
MakeleleriGetir();
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
MakeleleriGetir();
}
protected void btnNext_Click(object sender, EventArgs e)
{
CurrentPage += 1;
MakeleleriGetir();
}
protected void btnPrevious_Click(object sender, EventArgs e)
{
CurrentPage -= 1;
MakeleleriGetir();
}
}
}
Logic:
Use ItemDataBound event and compare currentpage with current value of btnPage. You may use FindControl to get the current btnPage value.
Hope that helps!
protected void repeaterPager_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
//Enabled False for current selected Page index
LinkButton lnkPage = (LinkButton)e.Item.FindControl("btnPage");
if (lnkPage.CommandArgument.ToString() == (CurrentPage+1).ToString())
{
lnkPage.Enabled = false;
lnkPage.BackColor = System.Drawing.Color.FromName("#FFCC01");
}
}
I would like to validate numbers input in text box.
I want the user to input only integer, decimal in the box between a maximum and minimum values.
How can I make sure of this?
Thank you.
Use a VerifyListener as this will handle paste, backspace, replace.....
E.g.
text.addVerifyListener(new VerifyListener() {
#Override
public void verifyText(VerifyEvent e) {
final String oldS = text.getText();
final String newS = oldS.substring(0, e.start) + e.text + oldS.substring(e.end);
try {
BigDecimal bd = new BigDecimal(newS);
// value is decimal
// Test value range
} catch (final NumberFormatException numberFormatException) {
// value is not decimal
e.doit = false;
}
}
});
You can register a ModifyListener with the text control and use it to validate the number.
txt.addModifyListener(new ModifyListener() {
#Override
public void modifyText(ModifyEvent event) {
String txt = ((Text) event.getSource()).getText();
try {
int num = Integer.parseInt(txt);
// Checks on num
} catch (NumberFormatException e) {
// Show error
}
}
});
You could also use addVerifyListener to prevent certain characters being entered. In the event passed into that method there is a "doit" field. If you set that to false it prevents the current edit.
Integer validation in SWT
text = new Text(this, SWT.BORDER);
text.setLayoutData(gridData);
s=text.getText();
this.setLayout(new GridLayout());
text.addListener(SWT.Verify, new Listener() {
public void handleEvent(Event e) {
String string = e.text;
char[] chars = new char[string.length()];
string.getChars(0, chars.length, chars, 0);
for (int i = 0; i < chars.length; i++) {
if (!('0' <= chars[i] && chars[i] <= '9')) {
e.doit = false;
return;
}
}
}
});
If you only want to allow Integer values you could use a Spinner instead of a text field.
For the validation of Double values you have to consider that characters like E may be included in Doubles and that partial input like "4e-" should be valid while typing. Such partial expressions will give a NumberFormatException for Double.parseDouble(partialExpression)
Also see my answer at following related question:
How to set a Mask to a SWT Text to only allow Decimals
1.create a utill class implement verify listener
2.override verifytext method
3.implement your logic
4.create a object of utill class where you want to use verify listener (on text)
5.text.addverifylistener(utillclassobject)
Example :-
1. utill class:-
public class UtillVerifyListener implements VerifyListener {
#Override
public void verifyText(VerifyEvent e) {
// Get the source widget
Text source = (Text) e.getSource();
// Get the text
final String oldS = source.getText();
final String newS = oldS.substring(0, e.start) + e.text + oldS.substring(e.end);
try {
BigDecimal bd = new BigDecimal(newS);
// value is decimal
// Test value range
} catch (final NumberFormatException numberFormatException) {
// value is not decimal
e.doit = false;
}
}
2.use of verifylistener in other class
public class TestVerifyListenerOne {
public void createContents(Composite parent){
UtillVerifyListener listener=new UtillVerifyListener();
textOne = new Text(composite, SWT.BORDER);
textOne .setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
textOne .addVerifyListener(listener)
textTwo = new Text(composite, SWT.BORDER);
textTwo .setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
textTwo .addVerifyListener(listener);
}
}
text.addVerifyListener(new VerifyListener() {
#Override
public void verifyText(VerifyEvent e) {
Text text = (Text) e.getSource();
final String oldS = text.getText();
String newS = oldS.substring(0, e.start) + e.text + oldS.substring(e.end);
boolean isValid = true;
try {
if(! "".equals(newS)){
Float.parseFloat(newS);
}
} catch (NumberFormatException ex) {
isValid = false;
}
e.doit = isValid;
}
});
