FixedColumns or fixedRows in scrollable DataTable?

[sabya113]

Is There a way to keep any random column or row fixed while scrolling the rest of the datatable?

The datatable i am using is dynamic and contains approx. 20 columns.I need the first column to be fixed(name) while horizontal

scrolling..Any ideas on how it can be implemented.

(currently using RichFaces3.3X + jsf1.2)

Hi,

You could use that attrib to freeze some columns : frozenColCount

It's not the same for extendedDataTable, so if you once happen to switch, use this one: frozenColumns

If you also want to freeze rows, then I think you can basicely include them in the (table's or rows') header : since I suppose their content is not part of the data itself, but cames from another set of data, you just have to include them as header for rows or entire table.

Hope this will help

Thanks, but most of my tables are just rich:dataTable.

frozenColumns is also not a part of Release 3.3X

Seems i  have to migrate to

<

rich:scrollableDataTable> (ColumnsWidth are also not available for scrollableDataTable)

for now as cant migrate to version 4+(missing complex components)

Right, I didn't notice the frozenColumns trick was for 4+ only : my bad!.

Though, I thought you were using scrollable datatable (according to the topic's title). Then, actually that will not be easy...

Maybe could you use some h:pannelGroup around the columns that are not frozen and apply the scroll on them.

But that would be easier here if you could show your code, so that we can suggest according to what you actually have.

Lemme try.The problem is half of the headers are dynamic and defined in backing bean and othet half is hard coded.

The data may also vary(dynamic) and the operations also varies depending on the data.

I also have to use right click ContextMenu and all this happening in backing bean.So little muddled up.

Let me try ur suggestion..Will post the code if nothing works out

Thanks for the Patience
