Dropdownlistbox in a TableView

Can you submit some code?

BTW, The cells datatype must be com.sapportals.htmlb.enum.TableColumnType.USERfor dropdowns.

Regards.

Did you try using CellRenderer?

I've tried using the DefaultTableViewModel and then just added a DropdownListBox into the constructing Vector. But the DefaultTableModel is running the toString method of the DropdownListBox, so the Cells are filled with "com.sapportals.htmlb.DropdownListBox@50243d".

public TableViewModel getModel(){

Vector rows=new Vector();

Vector headers=new Vector();

headers.add("test");

headers.add("Dropdownlist");

for (int i=0;i<6;i++){

Vector cols=new Vector();

cols.add("test"+i);

cols.add(new DropdownListBox("testddb"+i));

rows.add(cols);

}

DefaultTableViewModel model=new DefaultTableViewModel(rows,headers);

model.getColumn("Dropdownlist").setCellType(1,TableColumnType.USER);

return model;

}

I've got no experience in using a Renderer.

Any sources for sourcecode would be nice to get into the whole thing.

Threre are no Changes, if I try to set the TableColumnType for the hole Column. I am actually trying to use my own Renderer Class. But still got no success. 😔

Hi guys,

You have to create a class which will be used to render the USER type cells. The cell renderer class is very simple. Something like this:

package .....

import com.sapportals.htmlb.rendering.*;

import com.sapportals.htmlb.table.ICellRenderer;

import com.sapportals.htmlb.table.TableView;

import com.sapportals.htmlb.DropdownListbox;

import com.sapportals.htmlb.enum.CellHAlign;

public class tableCellRenderer implements ICellRenderer {

public void renderCell (int row, int column, TableView tableView, IPageContext rendererContext) {

if (column == tableView.getColumn("YourColumnTitle").getIndex()) {

DropdownListbox drop = .....

drop.render(rendererContext);

}

}

}

So, with the if condition you identify the column you want and do whatever you like to it.

Back on the component class, you have to get a new instance of the class and tell the tableview about it with:

tableCellRenderer tcr = new tableCellRenderer();

yourTableView.setUserTypeCellRenderer(tcr);

Then declare which columns are USER type with:

yourTableView.getColumn("YourColumn").setType(TableColumnType.USER);

That's it!

Hope it helps!

Cheers

PS: On the DefaultTableViewModel you can only play with the actual data and metadata which the tableview will display. You can't mess around with its looks!

Finaly I got this whole stuff rendered with the ICellRenderer interface and everything looks like I want it to.

But!!

Now I am trying to implement an eventhandling and I don't get the selected value for the Dropdownlistboxes (DdLB). I'm getting the DdLB as an Object but neither the getValueAsDataType nor the getSelection method do return something different from null.

I don't have any clue what to do to get the value.
