Thanks Roshan. Yes it helped a lot.
Can you please let me know how to chnage the background colour of the column dynamically?
I used following code snipplet for doing the same:
Column basicColumn =
new Column();
basicColumn.setSortBy(
"basic" );
//Column Cell Style
UnifiedValueExpression uniValueExpressionColumnStyle = UnificationHelper.createUnifiedValueExpression(
basicColumn.setUnifiedValueBLOCKED EXPRESSION
{}
But it didn't work.
Please provide me code snipplet for setting the coloum background colour dynamically.
Hi Gautam,
Here are some code snippets for you. The bolded text is about the background colour
I hope they will help you
public void initEditGrid() {
FacesContext context = FacesContext.getCurrentInstance();
clearGrid();
HtmlGridEditing gridEditing = new HtmlGridEditing();
Class[] args = new Class[] { CellValueChangeEvent.class };
UnifiedMethodExpression methodExpr = UnificationHelper
.createUnifiedMethodBLOCKED EXPRESSION;
}
The snipped is in the attached file.
Hello , Goutam
Do you want to set the color in the row you have selected?
Is this what you mean ?
I understand that you want to set different color of each row by what you have said.
If you want this there is a way (the source code below is in the context of the snippet.txt)
editGrid
.setRowStyleClass("igGridRow"); // igGridRow is styleClass defines in igf_grid.css
editGrid.setRowAlternateStyleClass("igGridRowAlternate"); // igGridRowAlternate - styleClass
Keep in mind to define igGridRow and igGridRowAlternate in the igf_grid.css file inside the Theme
you are using :
.igGridRow
{background-color: #888888;}
.igGridRowAlternate
{background-color: #F5F5F5;}
I hope this helps!
Please let me know how can you retrieve the data from DATA_ROW and set the same in the following inside you java code:HtmlColumn firstNameColumn = new HtmlColumn ();firstNameColumn.setStyle("background-color: #AACC44;");
What i mean to say that the colour is set in the DATA_ROW object.During the creation of the table that should get pickedup and set in the column.How can it be possible to get the value from DATA_ROW in the java code?
