Hello,

I want to implement the following behaviour for a property grid. After a value has been altered via keyboard input and the user hits the tab key the focus shall be set to the next property item and its content shall be selected automaticaly, so that the value is overwritten as soon as a key is pressed.

Does the Xtreme PropertyGrid already have this behaviour or do I have to implement it myself? If second, how would I do that (can I catch the TabPressed event and set the focus tio the next item)?

Thanks
Stefan

Hello,

You can call m_wndPropertyGrid.NavigateItems(TRUE); to allow tab all items.

Hi Oleg,

thank you for the fast response!

But is there a way to prevent the key portion of an item (left part) from getting the focus? I want to step via the tab key through the item values only (value1->value2->value3 instead of value1->key2->value2->key3->value3).

Thanks in advance
Stefan

Hello,

Override

void CXTPPropertyGrid::OnNavigate(XTPPropertyGridUI nUIElement, BOOL bForward, CXTPPropertyGridItem* pItem) method.

Hello Oleg;

I need your help, how to Overwrite OnNavigate to get the results Stefan mentioned in his previous post.

Which part of OnNavigate has to be changed to tab through key1 -> key 2 -> key 3 ...

Thanks in advance

I did something like this to move the focus to the next item upon pressing RETURN:


void CXTPPropertyGridInplaceEdit2::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) 
{
 // on ENTER automatically go to next row and activate edit
 CXTPPropertyGridItem* pItem = GetItem();
 if(nChar == VK_RETURN && pItem && pItem->GetGrid()) {
  CXTPPropertyGridView* pGrid = pItem->GetGrid();
  int nIndex = pItem->GetIndex();
  if (nIndex < pGrid->GetCount() - 1) {
   if(pGrid->GetItem(nIndex+1)->IsCategory())
    nIndex++;
   if (nIndex < pGrid->GetCount() - 1) {
    pGrid->SetFocus();
    pGrid->SetCurSel(nIndex+1);
    pGrid->OnSelectionChanged();
    pItem = pGrid->GetItem(nIndex+1);
    pItem->OnSelect();
    pItem->SetFocusToInplaceControl();
    return;
   }
  }
 }
 
 CXTPPropertyGridInplaceEdit::OnChar(nChar, nRepCnt, nFlags);
}

this is code for XTP 9.81, dunno if it still works...

Hi Barto;

Thanks for your suggestions. In my case this is to restrictive because it depends on the edit control to be activated to navigate from item key to item key. Additional, in our case we have several items that do not have CXTPPropertyGridInplaceEdit derived edit controls. This would result in code duplication or multiple inheritance.

So I have to look for another solution to get the required results.
