Hi,

1. Is it possible to create a button (image button would be nice since the GridViewCommandColumn is just wrong for this, it should be a + and -) per row? I know you do not support Hierarchies but can I "infuse" a button?

2. On that button click I would like to increase the height of the Row to add a user control that will show details, pie charts, etc. This usercontrol should be as wide as the whole row (not only a cell).

I am thinking of hacking into the source code but now when Q2 is comming up... well it would be better not to have to migrate that code every time a service pack or version of the Telerik controls is released.

Thanks,
/ jorge

MDI child form title does not show when minimized

Here's how to reproduce the issue.

1. Create a MDI parent form.
2. Create a MDI child form that inherits from Telerik.WinControls.UI.ShapedForm.
3. Set the shape property of the child form to RoundRectShape.
4. Open the child form from within the parent form.
5. Minimize the child form.

Notice the title does not show.

Is there any way around this issue?

Thanks.

populate a ComboBox

I am trying to populate a ComboBox with data from a access db. I have the following code that works in a normal combobox, but with the radcombobox does nothing:

    
                            Dim ComboBox1 As New Telerik.WinControls.UI.RadComboBox 
        
                            Dim cn As OleDbConnection 
        
                            Dim connString As String = ligacao 
        
                            cn = New OleDbConnection(connString) 
        
                            cn.Open() 
        
                            Dim da As New OleDb.OleDbDataAdapter(sql, cn) 
        
                            Dim ds As DataSet = New DataSet 
        
                            da.Fill(ds, "Tabela") 
        
                            With ComboBox1 
        
                                .DataSource = ds.Tables(0) 
        
                                .DisplayMember = "D1" 
        
                                .ValueMember = "D2" 
        
                            End With

Can you tell me what I have to change to make it work?

Thanks

RadGridView's Tooltip supports only text?

Hi All,

I use the RadGridView to show text that is sometimes longer than the original cell. Since the complete text does not fit into the cell I decided to show a tool tip by using the ToolTipTextNeeded event. The problem is that this event only allows me to set a text for the tool tip. The tool tip itself disappears after only 5 seconds which makes it quite unusable for my implementation.

To find out why I cannot set an AutoPopDelay for the displayed tooltip I used a bit of Reflector magic and found out that the RadToolTip class being used is internal as well as the property that holds the tool tip for the cells. This is a bit stupid because now I can't even derive my own class.

In the end I decided to force the required values into the grid by using reflection but of course this is not the best way to solve this problem.

Shouldn't the ToolTipTextNeededEventArgs expose far more properties of the original tooltip or the entire tool tip itself?

Just in case someone else is having the some problem, I'll post my ToolTipTextNeeded event handler here:

    
            private void gviAufgaben_ToolTipTextNeeded(object sender, ToolTipTextNeededEventArgs e)
 
                    {
 
                        GridDataCellElement cell = sender as GridDataCellElement;
 
                        if (cell != null)
 
                        {   
 
                            ComponentBehavior behavior = cell.ElementTree.ComponentTreeHandler.Behavior;
 
                            PropertyInfo tooltip = behavior.GetType().GetProperty("ToolTip", BindingFlags.NonPublic | BindingFlags.Instance);
 
                            object tip = tooltip.GetValue(behavior, null);              
 
                            PropertyInfo autoPopDelay = tip.GetType().GetProperty("AutoPopDelay");
 
                            autoPopDelay.SetValue(tip, 60000, null);                
 
                            e.ToolTipText = cell.Value.ToString();              
 
                        }           
 
                    }

I hope that someone can come up with a better suggestion.

Thanks,

Sebastian

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.
