I want to change row height in Blazorise DataGrid.
How to do it? Thank you.
This code doesn't work:
public void OnRowStyling(TEntity entity, DataGridRowStyling styling)
=> styling.Style = "color: red; height: 10px;";
UPD: This part works: Style = "color: red;

I am working on a Javafx application and I tried to add some Labels, Buttons and Texts, which resizes when the user resizing the Scene. All Nodes are inside a VBox, which itself is inside a StackPane.
My test application:
public class Test extends Application
{
public static void main(String[] args)
{
launch(args);
}
#Override
public void start(final Stage primaryStage)
{
StackPane pane = new StackPane();
VBox box = new VBox();
box.setAlignment(Pos.CENTER);
Label l = new Label("Label");
Text t = new Text("Text");
t.getStyleClass().add("test");
Button b = new Button("Button");
pane.heightProperty().addListener(listener ->
{
double h = pane.getHeight()/5;
l.setFont(Font.font(l.getFont().getFamily(), h));
t.setFont(Font.font(t.getFont().getFamily(), h));
b.setFont(Font.font(b.getFont().getFamily(), h));
});
box.getChildren().addAll(l, t, b);
pane.getChildren().add(box);
primaryStage.setScene(new Scene(pane));
primaryStage.getScene().getStylesheets().add(Path.of("test.css").toUri().toString());
primaryStage.show();
}
}
If I resize the Stage it works as expected. But unfortunately only with pure Java code.
Because after adding my css file, the Labeled controls behave different. While the Text elements continue to change in size, the Labels and Buttons does not change their size anymore.
My css file, which does not work:
.label
{
-fx-text-fill: red;
-fx-font-family: impact;
}
.test
{
-fx-fill: red;
-fx-font-family: impact;
-fx-font-size: 2em;
}
.button
{
-fx-text-fill: red;
-fx-font-size: 2em;
}
I asked myself what I did wrong and have tested different css states. I found out, when I omit font values in css it works, otherwise it does not. Therewhile it does not matter which font value occurs, only one font value is required to miss the behavior.
My css file, which works:
.label
{
-fx-text-fill: red;
//-fx-font-family: impact;
}
.test
{
-fx-fill: red;
-fx-font-family: impact;
-fx-font-size: 2em;
}
.button
{
-fx-text-fill: red;
//-fx-font-size: 2em;
}
1. Question: -has changed, see below-
Do I missunderstand something about css and Javafx, or did I something wrong in my css file or is there a bug?
2. Question: -solved-
Have I to put the font values with java code or is there an other way to add the font?
Thank You for helping!
Update
As recommended I have studying the follow guide:
https://openjfx.io/javadoc/14/javafx.graphics/javafx/scene/doc-files/cssref.html
The JavaFX CSS implementation applies the following order of precedence:
The implementation allows designers to style an application by using style sheets to override property values set from code. For example, a call to rectangle.setFill(Color.YELLOW) can be overridden by an inline‑style or a style from an author stylesheet. This has implications for the cascade; particularly, when does a style from a style sheet override a value set from code? The JavaFX CSS implementation applies the following order of precedence: a style from a user agent style sheet has lower priority than a value set from code, which has lower priority than a Scene or Parent style sheet. Inline styles have highest precedence. Style sheets from a Parent instance are considered to be more specific than those styles from Scene style sheets.
In my case this means, I will use the inline style to make it proper.
thus the 2. Question is solved
But, because of Parent style sheet > value set from code, it also means, all Nodes are not allowed to change theire size, even the Text Node.
Therefore I changed my 1. Question to:
Why does the JavaFX CSS order of precedence differ between Text and Controls
Question 1:
It's not a bug, it's a conflict of priorities. .setFont() has a lower priority than that CSS. Just replace .setFont() to .setStyle() and sample will work as you planned:
l.setStyle("-fx-font-size:" + h + ";");
t.setStyle("-fx-font-size:" + h + ";");
b.setStyle("-fx-font-size:" + h + ";");
Question 2:
Try to keep all about styles in CSS. It's the best practice.
I have a TableView clear.
I have an button1, when I click this I added a row in my tableView and I select the row. This row is in red by the line css :
.table-row-cell:selected {-fx-background-color: red;}
Next, I have a button2, and I would like that when I click on the button2, the background color on my row selected change in blue.
Help me.
Thanks.
add this code into your .css file:
#blue_cell .table-row-cell:selected{
-fx-background-color: blue;
}
then add this into your java file
button2.setOnAction(e -> productsTable.setId("blue_cell"));
You have many ways for changing the values of properties in css from java code.
You can define a look-up color in css and use setStyle() method in java like that :
.table-view {
-selected-color:red;
}
.table-row-cell:selected{
-fx-background-color: -selected-color;
}
Then use setStyle() method :
button2.setOnAction(e -> table.setStyle("-selected-color:blue;"));
Is it possible to override a JavaFX CSS definition in code?
For example, in my CSS file I defined a button's height as follows:
.button {
-fx-pref-height: 30px;
}
When I try to override this height for some button in code...
Button button = new Button();
button.setPrefSize(100, 50); // width, height
...the button still has a height of 30 pixels.
There are two solutions:
Make sure that button.setPrefSize(100, 50); // width, height is called after the Button became visible.
Use Bindings to force its size (CSS does not overwrite bound values), for example: button.prefHeightProperty().bind(new SimpleDoubleProperty(60));
Consider the following widget:
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.ListBox;
import com.google.gwt.user.client.ui.TextBox;
import com.google.gwt.user.client.ui.HasHorizontalAlignment;
import com.google.gwt.user.client.ui.HasVerticalAlignment;
import com.google.gwt.user.client.ui.FlexTable;
public class SelectorPanel extends Composite
{
private final FlexTable flexTable = new FlexTable();
private final Label lbltitle = new Label("##Title");
private final ListBox listBox = new ListBox();
private final Label lblsearchtext = new Label( "##SearchText" );
private final TextBox tbSearch = new TextBox();
public SelectorPanel()
{
listBox.setVisibleItemCount( 10 );
flexTable.setStyleName("SearchPanel");
flexTable.setBorderWidth(0);
initWidget( flexTable );
flexTable.setSize("200px", "0px");
lbltitle.setWordWrap( false );
flexTable.setWidget( 0, 0, lbltitle );
flexTable.setWidget( 1, 0, listBox );
listBox.setWidth("100%");
flexTable.setWidget( 2, 0, lblsearchtext );
tbSearch.setMaxLength( 32 );
flexTable.setWidget( 3, 0, tbSearch );
flexTable.getCellFormatter().setHorizontalAlignment( 0, 0, HasHorizontalAlignment.ALIGN_LEFT );
flexTable.getCellFormatter().setVerticalAlignment( 2, 0, HasVerticalAlignment.ALIGN_MIDDLE );
flexTable.getCellFormatter().setVerticalAlignment( 1, 0, HasVerticalAlignment.ALIGN_MIDDLE );
flexTable.getCellFormatter().setVerticalAlignment( 3, 0, HasVerticalAlignment.ALIGN_MIDDLE );
flexTable.getCellFormatter().setVerticalAlignment(0, 0, HasVerticalAlignment.ALIGN_BOTTOM);
flexTable.getCellFormatter().setHorizontalAlignment(3, 0, HasHorizontalAlignment.ALIGN_CENTER);
}
}
I have tried messing with CSS spacing and padding (and I have no idea what the difference is) and it has no effect. I can even change colors in the CSS tool and that too has no effect.
Anyway, here are the problems with widget:
The title text "##Title" is cut off by the list box below it. I would like some spacing or padding below it so that doesn't happen.
The ##SearchText label is too close to the listbox above it and also overlapped by the text box below it.
Finally the whole thing appears at the extreme left on my browser and I would like a little spacing between it and the edge of the screen.
I can 'kind of' format this by adjusting cell sizes and what not. I can't get it right, only better. I am also thinking this must be the wrong way to go about it.
When I look at the stockwatcher application they use CSS to do things like this, but I can't get anything to happen. The following is my CSS file and the two items are just experimental and have no effect on anything.
Boxed {
margin-top: auto;
border: thin solid;
background-color: Silver;
}
#test {
margin-top: 20px;
margin-bottom: 20px;
padding-top: 20px;
padding-bottom: 20px;
}
Is there anyone who can explain this to me? I just do not understand why CSS has no effect or how to resolve the above problems. I can apply the above CSS to the cells or to the labels or other UI objects and nothing happens.
first of all i can't see your overlapping issues. See the picture. This looks good to me:
To the CSS-questions: You need to reference the Class-Name or the ID of you component. A class is referenced by ".className", an id by "#id".
If you want to move your widget to the left by 100 pixels you can use this CSS:
.SearchPanel{ margin-left:100px; }
Or you can even center it with:
.SearchPanel{ margin:auto; }
You applied the css-class "SearchPanel" in your code with:
flexTable.setStyleName("SearchPanel");
This way you can apply classes to every component.
If you wan't more spacing on the top and the bottom of your label (##Title and ##SearchText) you could add some margin as well:
.gwt-Label {
margin-top: 10px;
margin-bottom: 10px;
}
I change the border style and border color on a .net textbox to solid red respectively. After a postback I am attempting to return the textbox to its default values, but I cannot seem to get the color right. I have googled this, and tried to get the default values in the debugger, but the values in the debugger always look too dark of a gray when applied. Is there an easy way to return to the default look and feel of a textbox?
try this:
TextBoxTitle.BorderColor = System.Drawing.Color.Empty;
You can write two CSS classes:
.tb_with_border {
border: 1px #FF0000 solid;
}
.tb_without_border {
border: none;
}
.. and then you can change styles by assigning CssClass property of your textbox, for example:
Textbox1.CssClass = "tb_without_border";
or in markup:
<asp:TextBox id="Textbox1" runat="server" CssClass="tb_with_border" />
If you're just switching the particular element style off then this works:
Textbox1.BorderColor = Nothing
You should be using CSS to do this anyways...
Textbox1.Style.Remove("border")
txt_TextBox.BorderColor = System.Drawing.Color.Empty;
txt_TextBox.BorderStyle = BorderStyle.NotSet;
Simple. Add another textbox or dropdownlist with default values and make it hidden.
To RESET to defaults, just set your textbox's border color, width and style to that of the hidden textbox like so:
txtMyTextBoxToReset.BorderColor = txtHiddenTextBox.BorderColor;
txtMyTextBoxToReset.BorderWidth = txtHiddenTextBox.BorderWidth;
This works in all browsers and works for Drop down lists as well
