Hi Dirk !

I have a cell which is editable and attached display converter and data validators to it now, when i click on the cell and type some invalid value it works fine and validator mark value as RED and don't allow to commit.

So Now,

I want's to achieve the same behavior through the code like when some button is pressed, my cell becomes editable and if the passed values is not valid, then it should mark it as red and don't allow to commit.

I have tried several things, like first called EditCellCommand, which bring my cell in the inline edit mode, now i called updateCellCommand , which trys to commit wrong value, but instead of showing the error and marking the wrong value as red, it does nothing.

What are the required steps needed to achieve this behavior ?

Thanks,
SD Khan

That behaviour can not be achieved easily by using NatTable code. Marking the text red in a TextCellEditor is done by key listeners on the underlying Text Control. So if you want to trigger such behaviour you need to get in touch with the Text Control directly.

Also by calling the update command directly you are skipping the framework code for conversion and validation. The update command is fired if conversion and validation passes. You need to commit the current active editor. This is currently possible by using the ActiveCellEditorRegistry.

Yup, right , I have done following steps

1. Called edit cell command

EditCellCommand cmd = new EditCellCommand(getTable().getNatTable(), getTable().getConfigRegistry(), cell);
getTable().getNatTable().doCommand(cmd);

2.Get active cell editor

ICellEditor editor = ActiveCellEditorRegistry.getActiveCellEditor();

3. Set the text you want to set

editor.setEditorValue("wow");

4.Now, validate

editor.validateCanonicalValue(editor.getEditorValue(), new RenderErrorHandling(new ControlDecorationProvider(FieldDecorationRegistry.DEC_ERROR)));

Now, if the text is invalid, it will remain in the edit mode and will be marked as red.

But his behavior can only be achieved for text cell editors.
