Hello,

I think I have a simple question but I just cannot find the solution to it.

I want to restrict the text length of a CXTPPropertyGridItem.

This is what I've tried with no luck:

CXTPPropertyGridItem *pItem = pCategory->AddChildItem(new CXTPPropertyGridItem("Description"));

CXTPPropertyGridInplaceEdit *pEdit = &pItem->GetInplaceEdit();
pEdit->SetLimitText(10);

But this didn't work....

I also tried using a mask and that works but I am wondering if there's a better solution, I don't want to use the mask for this unless I have no choice.

Ideas anyone?

TIA,

Martin

I found it!!! It appears you just need to override class CXTPPropertyGridItem like i did for my UserField entity:


class CUserFieldEdit:public CXTPPropertyGridInplaceEdit
{
public:
 
      CUserFieldEdit():m_iMaxChars(0){};
 
      void SetMaxChars(int iMaxChars)
      {
              m_iMaxChars = iMaxChars;
      }
 
protected:
 
      virtual void Create(CXTPPropertyGridItem * pItem, CRect rect)
      {
              __super::Create(pItem, rect);
              
              if(m_iMaxChars)                               // If limit was defined;
                    SetLimitText(m_iMaxChars);    // Set the limit;
      }
 
private:
 
      int m_iMaxChars;
};
 
class CUserFieldItem:public CXTPPropertyGridItem
{
public:
      CUserFieldItem(LPCTSTR strItem, int iMaxChars):CXTPPropertyGridItem(strItem)
      {
              m_edit.SetMaxChars(iMaxChars);
      }
 
protected:
 
      virtual CXTPPropertyGridInplaceEdit & GetInplaceEdit()
      {
              return m_edit;
      }
 
private:
 
      CUserFieldEdit m_edit;
};

Then instead of


CXTPPropertyGridItem * pItem   = m_UFGrid.AddCategory(_T(""));
pItem->AddChildItem(new CXTPPropertyGridItem(_T("User Field 1")));

you'll be calling:



CXTPPropertyGridItem * pItem   = m_UFGrid.AddCategory(_T(""));
pItem->AddChildItem(new CUserFieldItem(_T("User Field 1"), 10));

Great, thank you!

This is one way to do it, but I was hoping for a more easier, obvious solution.

Hopefully the CJ team is willing to implement this into a next release!

Cheers!
