For what it's worth -- with the code that Gabriel sent for moving the
PropertyGrid
splitter I wrote a function that uses it in the following
PropertyGridManipulator
class in order to move the splitter bar over to fit the largest displayed name
of the property Grid (assuming you are using the DisplayNameAttribute for
properties of the PropertyGrid.SelectedObject). As I mentioned in the last
reply, the reflection stuff is circumventing privacy of the
PropertyGridView's MoveSplitterTo method, so this code may no longer work in
future versions of framework but the try-catch will prevent a crash.
<code>
public class PropertyGridManipulator
{
public static void MoveSplitter(PropertyGrid propertyGrid, int x)
{
object propertyGridView =
typeof(PropertyGrid).InvokeMember("gridView",
BindingFlags.GetField |
BindingFlags.NonPublic |
BindingFlags.Instance, null, propertyGrid, null);
propertyGridView.GetType().InvokeMember("MoveSplitterTo",
BindingFlags.InvokeMethod | BindingFlags.NonPublic | BindingFlags.Instance,
null, propertyGridView,
new object[] { x });
}
/// <summary>
/// Moves the property Grid's splitter bar over to fit the width of
the longest display name string + padding
///
/// </summary>
/// <param name="propertyGrid">The property Grid whose splitter bar
is to be moved</param>
/// <param name="iPadding">Right padding to include with longest
display name width</param>
public static void MoveSplitterToLongestDisplayName(PropertyGrid
propertyGrid, int iPadding)
{
try
{
Type pgObjectType = propertyGrid.SelectedObject.GetType();
string longestDisplayName = "";
// Iterate through all the properties of the class.
foreach (PropertyInfo mInfo in pgObjectType.GetProperties())
{
// Iterate through all the Attributes for each property.
foreach (Attribute attr in
mInfo.GetCustomAttributes(typeof(DisplayNameAttribute), false))
{
// Check for the AnimalType attribute.
if (attr.GetType() == typeof(DisplayNameAttribute))
{
DisplayNameAttribute displayNameAttr =
(DisplayNameAttribute)attr;
if (displayNameAttr.DisplayName.Length >
longestDisplayName.Length)
{
longestDisplayName =
displayNameAttr.DisplayName;
}
}
}
}
Size textSize = TextRenderer.MeasureText(longestDisplayName,
propertyGrid.Font);
PropertyGridManipulator.MoveSplitter(propertyGrid,
textSize.Width + iPadding);
}
catch (Exception exception1)
{
MessageBox.Show(exception1.Message);
//do nothing for now --
//if exception was thrown the private method MoveSplitterTo
//of the C# version 2.0 framework's PropertyGrid's
//PropertyGridView probably is no
//longer named the same or has a different
//method signature in the current C# framework
}
}//end public static void
MoveSplitterToLongestDisplayName(PropertyGrid propertyGrid, int iPadding)
}
