Hi,

if I try to add nodes with the nodes designer everything works fine except, there is no way to accept the changes. The nodes editor dialog has no accept button or something similar. Using the return doesn't help, too. Thereto, see attached image.

Regards

Martin

Allow only some columns as editable

1. GridView with mixture of text, decimal and combobox columns. I want to allow only combobox as editable, the rest are for display only. I don't see a property to override the default for the entire grid. Do I really have to handle an edit event and cancel if it's not a column where I wish to allow changes? If so, what's the event? If not, how can I set a specific column to allow edit or set other columns to disallow edit?

2. Is there an IsDirty for the entire grid so I can prompt the user to save? Is there an IsDirty for a column and/or a row so I can iterate through and write only the delta's unbound via an SQL stored proc? I would prefer to not have to track changes in my own code.

3. It doesn't seem like GridView likes to update the display properly from a background thread. Sometimes there's data, sometimes not, and sometimes not all the data. I don't want to suspend the UI while I'm loading data. I am running unbound.

Thanks

PanelBarGroupElement overlapping

Howdy folks,

I have a RadPanelBar that I am dynamically adding groups and items to. Things are starting to come together, but a few of my groups seem to have too many elements (radButtonElement) and are being overlapped by the next group below it. I am using the ExplorerBarStyle group style so I can expand and collapse my groups. Also, the groups are expanded by default when the form loads. When I collapse the groups that overlap the longer group, I can see the elements of the long group underneath the collapsed group headers. It seems like there is a set height for each panel or am I missing something?

Any help here would be wonderful. I hope that was enough information, but feel free to ask for any clarification. Thanks.

Dockpanel splitter onmouseover change color

Hi Telerik Team,

My application uses CAB SCSF and my layout has two workspaces (Left and right) where left deals with Navigation, right deals with the screen display. Over here I have a navgation bar in my left workspace which is dockable using a docking panel. Kindly help me out in setting the color of the splitter whenever we have the mouse over it. I mean to indicate the user that there is a splitter by showing it with a color.

Get rid of gradient background

I can't find a way to get rid of the default gradient backcolor of the raddock control. I've tried the following:

spltContainer.Style.SetValue(Telerik.WinControls.Primitives.FillPrimitive.GradientStyleProperty, Telerik.WinControls.GradientStyles.Solid)

And it has no effect. I've even tried getting the FillPrimitive child, and setting it's GradientStyle to Solid, but it just get's overwritten (if I set the value using RadControlSpy it works).

New behavior RacComboBox in Q1 2010

Hi everyone,

I'm working on a project in WinForms using the Telerik library. We previously used the Q2 2009 version of the library. In our project we use a RadComboBox wich is contains a bunch of default answers.But the combo accept custom text and when the user select a default answer, in the SelectedIndexChanged event we add to the text of the combo the selected awser seperated from the original text (saved in the tag of the combo when the dropdown is opened) by a " - ".

Here is the code :

    
            private void rcbElement_SelectedIndexChanged(object sender, EventArgs e) 
        
            { 
        
                        RadComboBoxEditorElement rcbe = (RadComboBoxEditorElement)sender; 
        
                        rcbe.Text = (rcbe.Tag.ToString() == "" ? "" : rcbe.Tag + (rcbe.Text == "" ? "" : " - ")) + rcbe.Text; 
        
                        rcbe.SelectedText = ""; 
        
                        rcbe.Tag = rcbe.Text; 
        
            }

But now with the new version (Q1 2010 SP2) this doesn't work anymore. The text of the combo remains the text of the selected item. How can we do that with the new version ?

Can't change value of combobox

Hello,
Strange thing when using your RadComboBox.
I have a comboBox bind to a dataTable.
When I'm trying to change the value of the comboBox It stay NULL.

Now, I check this And I've noticed something strange:
In debug, When I'm standing on the object "radComboBox1.selectedValue" I see the a value (lats say) '12345'.
If I click on the value it self (I'm using visual studio 2008) It goes into edit mode and then I see that the value is actually: '12345M'.

I don't have a clue where this 'M' come from. It doesn't appear any where in my sql,datatable or code.

I tried the some code with a simple comboBox And it was fine (with out the 'M').

Do you know this behavior?

Thanks,
Roy.

Page Up/Down

I am trying to achieve a page up/down functionality for a Point of sale.

Lets say the case where i have a listbox
Achored on all sides, and autoscroll enabled = true

with two bottons Page up / Page down

If I press page down button I want the list box to scroll down by the amount of its height.
How do I do this ?

I tried using for page down

radListBox1.AutoScrollOffset = new Point(0, (-1*radListBox1.AutoScrollOffset.Y)+radListBox1.Height);

I use a positive value for y point because it gets converted into negative and therefore I set the Y offset to a positive by multiplying it by -1.

With very little success.

Thank you in advance

Creating User Controls that inherit from DocumentWindow

I am using the 2010.1.10.409 version of the Telerik.WinControls.UI assembly to utilize the new DocumentWindow and RadDock Manager. I am creating a UserControl that inherits from DocumentWindow

                    using Telerik.WinControls.UI.Docking;         
                     
            public class myControl : DocumentWindow { }         

When I go into the design view to add controls I am only getting a blank gray screen. Also when I updated my older user controls that inherited from DockPanel to now inherit from DocumentWindow, all of the controls that were on the form are now just listed in the gray screen, meaning that they are not showing the design and layout that the DockPanel originally gave me.

Is this a known issue? Or is there something that I need to do to be able to have the design time support that the DockPanels had?
