The Q2 2009 RadDock control does not SetStyle(ControlStyles.ContainerControl) and so is not seen in .net as a ContainerControl. This causes problems when calling Form.ValidateChildren or Control.Validate to force validation of controls held in a RadDock window.

My workaround is to explicitly handle the radDock_Validating event in my code like this;

private void radDock_Validating(object sender, CancelEventArgs e)
{
    if(! ((ContainerControl)this.radDock.ActiveWindow).Validate())
    {
        e.Cancel = true;
    }
}

The .net framework behaves oddly when cascading the Validate event through a control stack, and instead of simply iterating a controls .Controls collection, it explicitly checks to see if a the Control.GetStyle(ControlStyles.ContainerControl) is true before deciding to iteratve the .Controls collection. Because RadDock does not set this property it is in effect telling the .net Framework "I don't have any children, so don't bother looking any further". By manually cascading the Validating event as shown above, we jump this gap.

I don't know if this particular pattern is followed in any other cascading functionality in the .net framework.

ToolTipText needed

Hello!
Look, I have a user control that works as a ToolBar that has some radbuttons on it. Those buttons are showing an image stored in the resources of the project, and I need to show a ToolTipText.

First I set the needed text through the properties window of each button (inside the RootElement property), and it didn't work.

Then I went to the designer.cs of the control and set manually the property (myButton.RootElement.ToolTipText = "some text"), and it didn't work.

Then, inside the designer.cs of the control I set manually the property in this way: ((Telerik.WinControls.UI.RadButtonElement)(MyButton.GetChildAt(0))).ToolTipText = "Open Model";. And guess what? ... It didn't work also!

Please help me, I don't know what else I can do.

Buttons, RadioButton, CheckBox, etc

Tab separator in WinForms?

It appears the WinForms radTabStrip does not support IsSeparator like the ASP.Net versions do. Is there any way to place 3 tabs left aligned and 2 tabs right aligned all on a single row?

Thanks!

Custom filtering

Hello,

Does the new release support the functionality of a custom filter row (I read in previous posts that you plan to do so)?

For example, my grid contains a column with enum values, I want to filter the rows in the grid by selecting one of the values from a drop down list.

Thanks

Cancelling the PanelBarGroup Expand/Collapse

It seems that in the 8.1.0.0 release, the PanelBarGroupExpanding and PanelBarGroupCollapsing "cancel" argument is not respected in the VS2005Toolbox GroupStyle. I haven't tried other styles because we like the look and feel of the VS2005Toolbox style.

When I set args.Cancel = true, the "Expanded" and "Collapsed" events are still fired and the +/- icon toggles, and the arg.Group's "Expanded" property is already changed at this point.

Is this something that is fixed with a newer release of the WinControls suite? Thanks!

RadPanelBar with "Protected" modifiers

Hello

I'm currently using RadPanelBar with a single panel group element in an inheritable form where I'm programming a set of common functions for all the forms that will inherit from it. I set the RadPanel modifiers property to "protected" so I can add new group elements in each inherited form for their particular functionality.

But when I am dessigning the inherited form, RadPanelBar properties appear as in read only mode, so I cannot add new panel groups, new controls in the panel group that already exists... etc.

Am I missing something? Is not possible use this control in the way I'm trying to?

Thank you in advance for your response.

AutoSizeRowsMode

Hi,
Qs1: How can I set auto size rows mode for the radGridView?

For the windows datagridview, When the cell data is wider than the column, having the auto size rows mode set to Displayed cells will resize the row to show all cell data. How can I have the same in a radgridview?

Qs2: Is there a way to set tool tip text for those cells that have data hidden due to less column width?

Hope you will have solutions for these..

Bottom Row Overwrites Grid Border

Hello,

I've discovered an issue in my gridviews where the last row paints over the grid's bottom border when the grid is full of information. Is there a way that I can make the grid border draw on top of the rows? If you guys have trouble reproducing this, let me know and I'll send a theme where this occurs. It actually occurs in all of my themes, so I imagine you guys wont have much trouble. I use a row-height of 18 if that helps.

Thanks!

Dynamically Resize GridHeaderRowElement?

In order to try to bend the will of the GridView to do something we're attempting, I'm trying to dynamically either completely hide or to change the height of a SPECIFIC group header row down to something 1 pixel in height if the group text is blank.

I've tried all of the following:

    
                        if (e.RowElement is GridGroupHeaderRowElement) 
        
                        { 
        
                            e.RowElement.Size = new Size(1, 1); 
        
                            e.RowElement.ShouldPaint = false; 
        
                            e.RowElement.Visibility = ElementVisibility.Hidden; 
        
                            e.RowElement.MinSize = new Size(e.RowElement.Size.Width, 0); 
        
                            e.RowElement.Size = new Size(e.RowElement.Size.Width, 1); 
        
                            e.RowElement.CoercedSize = new Size(e.RowElement.Size.Width, 1); 
        
                            e.RowElement.StretchVertically = false; 
        
                            this.ApplyThemeToElement(e.RowElement, "ControlDefault"); 
        
                        }

All this has done has completely hidden the group rows but still leaves blank space where they shuold be, however now I can't select them (which is nice).

Is there any way to change the size so the space left when hidden is minimized?

Thanks in advance.
