Grid Caption

I would have thought that the Text property will set the caption of the grid but it does not do it. Any idea what is the use of Text property?

More important how do I set the caption for the grid ( other than putting a separate label on the top og the grid )

Get all child panels

I am trying to persist the layout of all panels to disk whenever they are closed. I'm running into a few issues (which may be moot if there is an easy way/pattern to persist to disk which I just overlooked).

I have a DockPanel which contains a user control with its own DockingManager and DockPanels. In an ealier thread (and based on my experience) I know that the Closed event does not get called on the subordinate DockPanels. That's ok, I can work around that.

The problem I have now is that *I'm* trying to call a method on all subordinate DockPanels and I cannot find them all. Here's what I'm doing:

//This part is called on the parent DockPanel,
//which is subclassed to support the "Save" method to persist to disk
  private void SubClassedDockPanel_Closed(object sender, EventArgs e)
  {
   this.Save();
   this.SaveAllChildren(this.Controls);

   if (AfterClosed != null)
   {
    AfterClosed(sender, e);
   }
  }

  private void SaveAllChildren(ControlCollection controls)
  {
   foreach (Control c in controls)
   {
    SaveAllChildren(c.Controls);

    if (c as IDockManager != null)
    {
     IDockManager dManager = c as IDockManager;
     foreach (IDockingSite site in dManager.DockingSites)
     {
      foreach (IDockable panel in site.ManagedDockables)
      {
       if (panel as SubClassedDockPanel != null)
       {
        (panel as SubClassedDockPanel).Save();
       }
      }
     }
     return;
    }
   }
  }

basically I look for any DockingManagers in the parent DockPanel's controls and then iterate over all of their ManagedDockables in all the DockingSites. This works with the exception of when I AutoHide a child DockPanel.

There are a few difficulties I've encountered regarding "AutoHide". First is that it causes the Closed event to fire on the child panel that is being unpinned. I'd like to understand why this is happening, and (leading into my second difficulty) where does it go? The algorithm above will not find the autohidden DockPanel.

Any assistance is greatly appreciated, I know I've posted a few questions today,
Sid

Docking assistant must be used twice

I have a DockPanel, created at runtime, which contains a user control with its own DockingManager and DockPanel layout. If I float any of the child DockPanels and then try to reattach them to their original location I have to perform the operation twice. The first time the window moves near the button on the assistant, and the second time it actually locks into place.

Restrict docking sites

I have two separate forms which may be open at the same time and I don't want users to be able to dock panels from one form in the other.

Could someone point me in the direction of an example of how to restrict the potential docking sites for a dock panel at runtime.

I've looked into the DockingManager, but it appears to be all or nothing... or I'm just not using it correctly.

Thanks in advance,
Sid

Scrollbar / Redisplay issues with Panelbar

Hi All

I am currently assessing whether to use / purchase the RadControls for WinForms.

I am having some display problems when using multiple (10 or more) PanelGroups within a PanelBar.

I need to show a subset of the groups so I hide some using
Visibility = ElementVisibility.Collapsed
But the scrollbar appears to have a length associated with all the groups whether they are visible or not. Can I control the scrollbar length to only be that of what is on the PanelBar?

Also when the groups sub-panels have multiple items in (a few controls) the scroll repaint leaves the panels overdrawing each other. Again, is this something that can be worked around?

An example project highlighting these issues can be supplied on request.

I hope you can help!

Best Regards,

David

Maximized Form?

I created a shaped form with the "rounded rectangle" look.

I set it to start out maximized and when I run the app the form is taking up about 3/4 of my screen. Its definitely maximized because I can't move it and if I double click the title bar it goes back to its default size.

Any ideas?

Align RadToolStripElement and/or RadToolStripItem all the way to the right

Is there any way to align either the RadToolStripElement control or the RadToolStripItem control all the way to the right of its RadToolStrip container?

When using the MS-provided ToolStrip control, it's just a matter of setting the alignment property of a ToolStripItem.

I see there is an "alignment" property exposed for the RadToolStripItem control. However, changing the property value doesn't really seem to work as I would expect it to. For example, I have three RadToolStripItems within a RadToolStripElement. Initially, all three of them had the alignment property set to "MiddleLeft" by default. Then, I changed the third one's alignment property to "MiddleRight" in hopes that it would do what I was hoping it would. Unfortunately, it didn't do what I expected. Instead, the third item is actually showing on top of the second item. I initially thought perhaps it's due to the ToolStripElement's autosize property having been set to True. So I set it to False and resized the control to make it bigger but I still can't get the third item to align right.

Is there another property/method for what I am trying to do?

Pb set vertical scroll value on RadTreeView loading

Hello,

I would like to set the vertical scroll bar on a given value when I load a RadTreeView. But I face the following problem :

After the RadTreeView loading, the Minimum and Maximum properties of RadTreeView.VScrollBar object remain to 0. So the value I want to apply is forbidden.

What is the correct way to achieve this ?

Thanks in advance,

Laurent VP.
