I have a UserControl which has a Label at the bottom right corner defined as followed:
this.lblInspectionName.AutoSize = true;
this.lblInspectionName.Font = new System.Drawing.Font("Segoe UI", 10.25F, System.Drawing.FontStyle.Bold);
this.lblInspectionName.Location = new System.Drawing.Point(3, 7);
this.lblInspectionName.Name = "lblInspectionName";
this.lblInspectionName.Size = new System.Drawing.Size(113, 19);
this.lblInspectionName.TabIndex = 0;
this.lblInspectionName.Text = "___";
Its Text content changes based on other events. The problem is that when the Label gets bigger, it goes to left (as I want otherwise it exceeds the right border), but when it gets smaller again the location is the same as the previous case and it's positioned too left.
Do you know how I can let the label grows to left when necessary keeping always a certain distance/margin to the right border? Thanks in advance!
EDIT
Doing as suggested, the situation is the following:
I would add these properties settings
this.lblInspectionName.Dock = DockStyle.Bottom;
this.lblInspectionName.TextAlign = ContentAlignment.BottomRight;
But you need to set the AutoSize back to false.
// Comment out this line. False is default
// this.lblInspectionName.AutoSize = true;

I need to show/hide some data points in oxyplot line series. Is it possible?
Though some markers are invisible, the line should go through the invisible markers.
You could make use of two series to achieve this. The first one would draw the complete points (and line) without the marker. The second series would draw the visible points(with marker,but with line style set to none). For Example
DataPoint[] points = new DataPoint[]
{
new DataPoint(1,12),
new DataPoint(2,10),
new DataPoint(3,9),
new DataPoint(4,13),
new DataPoint(5,14),
new DataPoint(6,10)
};
var seriesComplete = new OxyPlot.Series.LineSeries();
seriesComplete.Points.AddRange(points);
var seriesVisible = new OxyPlot.Series.LineSeries();
seriesVisible.Points.AddRange(points.Where(x => x.Y % 2 == 0));
seriesVisible.MarkerFill = OxyColors.Blue;
seriesVisible.MarkerType = MarkerType.Circle;
seriesVisible.MarkerSize = 10;
seriesVisible.LineStyle = LineStyle.None;
this.MyModel.Series.Add(seriesComplete);
this.MyModel.Series.Add(seriesVisible);

Derived from Jeff S's methodology found here, I can add a "Checkbox" to a PDF page like so:
PdfPTable tblFirstRow = new PdfPTable(5);
tblFirstRow.SpacingBefore = 4f;
tblFirstRow.HorizontalAlignment = Element.ALIGN_LEFT;
. . . // code where textboxes are added has been elided for brevity
PdfPCell cell204Submitted = new PdfPCell()
{
CellEvent = new DynamicCheckbox("checkbox204Submitted", "204 Submitted or on file")
};
tblFirstRow.AddCell(cell204Submitted);
doc.Add(tblFirstRow);
The DynamicCheckbox class, based on Jeff S's CustomCellLayout class, is:
public class DynamicCheckbox : IPdfPCellEvent
{
private string fieldname;
private string cap;
public DynamicCheckbox(string name, String caption)
{
fieldname = name;
cap = caption;
}
public void CellLayout(PdfPCell cell, Rectangle rectangle, PdfContentByte[] canvases)
{
PdfWriter writer = canvases[0].PdfWriter;
RadioCheckField ckbx = new RadioCheckField(writer, rectangle, fieldname, "Yes");
ckbx.CheckType = RadioCheckField.TYPE_CHECK;
ckbx.Text = cap;
PdfFormField field = ckbx.CheckField;
writer.AddAnnotation(field);
}
}
My problem is that the checkbox's text (the string assigned to ckbx.Text) is not displaying. The checkbox (outsized) occupies the last cell in the table row, but there is no (visible) accompanying text.
What's missing from my code?
Note: I tried to reduce the size of the checkbox by doing this:
Rectangle tangle = new Rectangle(20, 20);
//RadioCheckField ckbx = new RadioCheckField(writer, rectangle, fieldname, "Yes");
RadioCheckField ckbx = new RadioCheckField(writer, tangle, fieldname, "Yes");
...but that attempt failed - with that code, I can't even "find" the checkbox in the generated PDF file - clicking willy-nilly in column 5 conjures up no checkbox...
Others have answered the label part. The Rectangle that you have called "tangle" needs to be calculated off of the rectangle that comes into the event handler, similar to
Rectangle tangle = new Rectangle(
rectangle.Left,
rectangle.Top - PDFStyle.boxsize - 4.5f,
rectangle.Left + PDFStyle.boxsize,
rectangle.Top - 4.5f
);
Where PDFStyle.boxsize is the width/height of the checkbox and 4.5f is the padding the edge of the cell. Basically the rectangle isn't relative to the cell, but absolute to the page.
As described in ISO-32000-1, a check box is a field of type Button. If you define text for a button, you want to define the text that is displayed on the button. However: in the case of a check box, there is no such text! Instead, you have two appearances, one for the Off value and one for the Yes value.
An educated guess made by an attentive reader would be that you don't want to add text (to the button), but that you want to add a label (for a checkbox). Again you should consult ISO-32000-1 and you'll discover that the spec doesn't say anything about labels for check boxes. The concept just doesn't exist at the level of an AcroForm.
This doesn't mean the concept doesn't exist in general. Many PDF tools allow you to define check boxes that are preceded by a label. When you look inside the PDF, you'll discover that this label is just part of the content, whereas the check box is represented by a widget orientation.
Let's take a look at the official documentation instead of frustrating ourselves searching on every place of the web except on the official web site. More specifically: let's take a look at the Buttons example from Chapter 7 of my book. You'll see that one can set text for a real button:
PushbuttonField button = new PushbuttonField(writer, rect, "Buttons");
button.setText("Push me");
This isn't possible with check boxes (for the obvious reason that the appearance of a check box is completely different). If we want to add a label, we can add it for instance like this:
checkbox = new RadioCheckField(writer, rect, LANGUAGES[i], "Yes");
field = checkbox.getCheckField();
field.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, "Off", onOff[0]);
field.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, "Yes", onOff[1]);
writer.addAnnotation(field);
ColumnText.showTextAligned(canvas, Element.ALIGN_LEFT,
new Phrase(LANGUAGES[i], font), 210, 790 - i * 40, 0);
You can find the C# version of these examples here: http://tinyurl.com/itextsharpIIA2C07
Creating a checkbox, and then accompanying text to its right, can be done like this:
PdfPCell cell204Submitted = new PdfPCell()
{
CellEvent = new DynamicCheckbox("checkbox204Submitted")
};
tblFirstRow.AddCell(cell204Submitted);
// . . . Chunks and an anchor created; that code has been elided for brevity
Paragraph parCkbxText = new Paragraph();
parCkbxText.Add(Chunk204SubmittedPreamble);
parCkbxText.Add(ChunkBoldNote);
parCkbxText.Add(Chunk204Midsection);
parCkbxText.Add(anchorPayeeSetup204);
PdfPCell cellCkbxText = new PdfPCell(parCkbxText);
cellCkbxText.BorderWidth = PdfPCell.NO_BORDER;
tblFirstRow.AddCell(cellCkbxText);
public class DynamicCheckbox : IPdfPCellEvent
{
private string fieldname;
public DynamicCheckbox(string name)
{
fieldname = name;
}
public void CellLayout(PdfPCell cell, Rectangle rectangle, PdfContentByte[] canvases)
{
PdfWriter writer = canvases[0].PdfWriter;
RadioCheckField ckbx = new RadioCheckField(writer, rectangle, fieldname, "Yes");
ckbx.CheckType = RadioCheckField.TYPE_CHECK;
ckbx.BackgroundColor = BaseColor.ORANGE;
ckbx.FontSize = 6;
ckbx.TextColor = BaseColor.WHITE;
PdfFormField field = ckbx.CheckField;
writer.AddAnnotation(field);
}
}
I have a Rad Command Bar created with the code below:
RadCommandBar main = new RadCommandBar();
main.Dock = DockStyle.Top;
main.AutoSize = true;
main.Size = new System.Drawing.Size(874, 59);
CommandBarRowElement address = new CommandBarRowElement();
CommandBarStripElement strip = new CommandBarStripElement();
strip.FloatingForm = null;
strip.StretchHorizontally = true;
address.Strips.Add(strip);
CommandBarDropDownList addressEdit = new CommandBarDropDownList();
addressEdit.MaxSize = new System.Drawing.Size(0, 0);
addressEdit.VisibleInOverflowMenu = true;
addressEdit.StretchHorizontally = true;
main.Rows.Add(address);
parent.Controls.Add(main);
I'm having issue with hiding the "Add or Remove Buttons" of the strip element. Can someone point me to the right way to hide that menu?
You can use the following code:
strip.OverflowButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
It it better to set the Visibility to Collapsed, in order to collapse the whole item. Using Hidden will hide the item, but its space will be retained. More information is available here: Customize the overflow button
I have a grid within a grid and i want the content of the second to move about without encroaching on the first grid.
Much like the panorama view but can move left or right as well as up and down.
I can get this working but unfortunately when you move down the top overflows into the outer grid overlapping any controls within it.
Is there a way to hide the overflow almost like CSS overflow:hidden?
Any help would be really appropriated.
Thank you
Andrew
Possible solution:
var gridWidth = (this.tilesize * (this.gridSize - 1)) / 2;
var top = -(((-offsetY + tileY) * this.tilesize) - gridWidth);
var left = -(((-offsetX + tileX) * this.tilesize) - gridWidth);
this.Container.Margin = new Thickness(left, top, 0, 0);
var clipSection = new RectangleGeometry();
clipSection.Rect = new Rect(-1 * left, -1 * top, 480, 400);
this.Container.Clip = clipSection;
this.Container.Dispatcher.BeginInvoke(new ThreadStart(delegate
{
this.Container.Clip = clipSection;
}));
You could do this by putting something in the cells of the "outer" grid and seeing a higher ZIndex than the elements you are moving around. The elements with the higher ZIndex appear above the lower ones.
The problem: I am not getting a textbox setting that will have a horizontally wordwrap and vertically auto grow functionality. I wish to do that by writing a code. I have written following code that creates a text box at mouse dblclick with wordwrap:
TextBox text2 = new TextBox();
text2.Width = 500;
text2.Visibility = Visibility.Visible;
text2.Focus();
text2.Height = 30;
text2.HorizontalAlignment = HorizontalAlignment.Left;
text2.VerticalAlignment = VerticalAlignment.Top;
Point p = e.GetPosition(LayoutRoot);
text2.Margin = new Thickness(p.X, p.Y, 0, 0);
LayoutRoot.Children.Add(text2);
But, textbox does not grow vertically.
Can somebody suggest me a code in C# to do exactly what I desire?
try using this
Grid grid = new Grid();
grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
grid.RowDefinitions.Add(new RowDefinition());
TextBox textBox = new TextBox() { Width = 100, TextWrapping = TextWrapping.Wrap };
textBox.SetValue(Grid.RowProperty, 0);
grid.Children.Add(textBox);
window.Content = grid;
where window is the Name assigned to Window(root).
One way to accomplish the growth you're looking for is to use a string measuring mechanism which you would run any time the text in your text box changes. Simply measure and resize your text box accordingly with any change to the contents.
Have you tried this?
text2.Height = double.NaN; // or don't set the property, but some custom styles might give a default value ..
text2.TextWrapping = TextWrapping.Wrap;
text2.MinHeight = 30; // or not if you want the styles default
instead of
text2.Height = 30;
not setting it or using double.NaN is the same as using 'Auto' in xaml.
