1025	TextMaximum	Text value and DicomVR.Length is the maximum number of bytes allowed.
1026	TextMaximumGroup	Text value and DicomVR.Length is the maximum number of bytes allowed per component group.

Example

using Leadtools; 
using Leadtools.Dicom; 
 
 
public void TestVRTable() 
{ 
 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
 
   //We don't need to call this since the DicomEngine.Startup already does that for us 
   //These calls are for demonstration purposes only 
   DicomVRTable.Instance.Reset(); 
   DicomVRTable.Instance.Default(); 
 
   //We can also call FindByIndex if we know the index of this VR 
   DicomVR vr = DicomVRTable.Instance.Find(DicomVRType.AE); 
   DicomVRTable.Instance.Delete(vr); 
 
   DicomVR vr1 = DicomVRTable.Instance.Insert(DicomVRType.AE, "My AE VR", 16, DicomVRRestriction.StringFixed, 1); 
   Debug.Assert(DicomVRTable.Instance.Exists(vr1) == true); 
   DicomVRTable.Instance.SetName(vr1, "My New AE VR"); 
 
   int count = 0; 
   //If we want to loop through all the VRs in the table we can do this: 
   vr = DicomVRTable.Instance.GetFirst(); 
   while (vr != null) 
   { 
      // We can also access the rest of the properties of DicomVR in here, 
      // such as DicomVRType.Code, DicomVRType.Length, DicomVRType.Name, 
      // DicomVRType.Restriction and DicomVRType.UnitSize 
      if (vr.Code == DicomVRType.AE) 
      { 
         Console.WriteLine(vr.Name); 
      } 
      count++; 
      vr = DicomVRTable.Instance.GetNext(vr); 
   } 
   //We can use GetLast and GetPrevious to achieve the same thing 
 
   Debug.Assert(count == DicomVRTable.Instance.GetCount()); 
 
   DicomEngine.Shutdown(); 
}
