Limiting label length when editing


To limit the length of text that can be entered when editing an item label, you have to add a handler for the TVN_BEGINLABELEDIT notification. Within this handler get the edit control and call the LimitText() function.
 
void COutline::OnBeginLabelEdit(NMHDR* pNMHDR, LRESULT* pResult) 
{
        TV_DISPINFO* pTVDispInfo = (TV_DISPINFO*)pNMHDR;
        
        // Limit text to 127 characters
        GetEditControl()->LimitText(127);

        *pResult = 0;
}

  • TreeCtrl - Label visualization limited to 260 characters

    Even if I set the label length longer than 260 characters through "myTreeCtrl.GetEditControl()->LimitText(500);" instruction, the visualization is limited to 260 characters.
    Is there a way to remove this limit ?
    Any suggestion is welcome.

    Bye
