dynamic rows and colums in GridView

cesar posted over 16 years ago

hello, i need to populate a GridView dynamically, i've created the colums already, but i don't know how to fill the rows???

I 've tried with Cells, but i don't find a function to put the label i want to show,

i got the following code:

       tabla=new HtmlGridView();
        HtmlOutputText tit=new HtmlOutputText();
        tit.setValue("Monitoreo a Caja");
        tabla.setHeader(tit);

        com.infragistics.faces.grid.component.Column col1=new com.infragistics.faces.grid.component.Column();
        HtmlOutputText enc1=new HtmlOutputText();
        enc1.setValue("Header 1");
        col1.setHeader(enc1);
        tabla.getColumns().add(col1);

        com.infragistics.faces.grid.component.Column col2=new com.infragistics.faces.grid.component.Column();
        HtmlOutputText enc2=new HtmlOutputText();
        enc2.setValue("Header2");
        col2.setHeader(enc2);
        tabla.getColumns().add(col2);

        HtmlOutputText valor1=new HtmlOutputText();
        valor1.setValue("valor1");
        HtmlOutputText valor2=new HtmlOutputText();
        valor2.setValue("valor2");
        com.infragistics.faces.grid.component.RowItem ren1=new com.infragistics.faces.grid.component.RowItem();

        com.infragistics.faces.grid.component.Cell cel1=new com.infragistics.faces.grid.component.Cell();
        com.infragistics.faces.grid.component.Cell cel2=new com.infragistics.faces.grid.component.Cell();

        HOW DO I PUT THE LABEL????????

        ren1.getCells().add(cel1);
        ren1.getCells().add(cel2);

        tabla.getRows().add(ren1);

thanks.

Hello,

You have to add the labels to the cells, here are the two lines you can add to you existing code to display labels.
com.infragistics.faces.grid.component.Cell cel1=new com.infragistics.faces.grid.component.Cell();
com.infragistics.faces.grid.component.Cell cel2=new com.infragistics.faces.grid.component.Cell();

//Add Component to the cells

cel1.getChildren().add(valor1);

cel2.getChildren().add(valor2);

ren1.getCells().add(cel1);

ren1.getCells().add(cel2);

Hi,

I have a similar requirement of creating the grid dynamically (both rows and columns). For this I have created a gridView binding and populating the grid in my backing bean. But unfortunately I am not getting sucess. Could you please help me in this. Basically what sould be the dataSource and how to create grid view in backing bean. If someone could share a sample code that will be very much helpful.

At runtime I get the information of number of rows and columns to be displayed. As of now I tried in the following way:

Web page:
<fic:gridView id="scoreCalculationPointsGridViewId"
binding="#{testBean.scorePointCalculationPointGridView}"

dataSource="#{testBean.scorePointCalculationPointDataModel}"

>

Backing Bean:
private HtmlGridView scorePointCalculationPointGridView;

private DataModel scorePointCalculationPointDataModel;
public HtmlGridView getScorePointCalculationPointGridView() {
createDynamicGrid();
return scorePointCalculationPointGridView;
}

private void createDynamicGrid(){
List dataModel = new ArrayList();
List tempList = new ArrayList<String>();
dataModel.add(tempList);
scorePointCalculationPointDataModel = new ListDataModel(dataModel);
scorePointCalculationPointGridView=new HtmlGridView();
HtmlOutputText tit=new HtmlOutputText();
tit.setValue("TABLE");
scorePointCalculationPointGridView.setHeader(tit);
Column col1=new Column();
HtmlOutputText enc1=new HtmlOutputText();
enc1.setValue("Header 1");
col1.setHeader(enc1);

scorePointCalculationPointGridView.getColumns().add(col1);
HtmlOutputText valor1=new HtmlOutputText();
valor1.setValue("valor1");
RowItem ren1=new RowItem();Cell cel1=new Cell();
cel1.getChildren().add(valor1);

ren1.getCells().add(cel1);

scorePointCalculationPointGridView.getRows().add(ren1);

}

When I am executing this then I am not getting the rows displayed. Only the heading of the column and a blank row.

Thank you
