No difference in selected items and 'current' item due to styles in Q1 2010 SP2

Hi all,

I have upgraded my application from Q1 2010 SP1 to Q1 2010 SP2 to fix a memory leak. However, in this new Service Pack I encounter another problem:

I have a couple of listboxes with multiselect, in which the user can select multiple items. I use the theme Office 2007 Silver in my application, and in Q1 2010 SP1 (and older versions) it was clear: selected items had a grey background and the 'current' item had a grey border around the item. So when a user deselects an item it changes from a grey background (selected) to a grey border (current). See also the first attached screenshot.

In SP2 however, the styles\themes seem to have changed. Both the selected items and the current item are now orange. The exact same color of orange... So the difference between the selected items and the 'current' (possibly not-selected) item is not visible. Also when a user deselects an item, it is not visible that the item is deselected until the users selectes another item. See the second attached screenshot.

This is not only with the Office 2007 theme but also with other themes. The only theme so far where this still works correct is 'Breeze', which I am not going to use in my application. Is this a mistake with the themes/styles or is this intentional? Can I adjust this by making my own theme (copied from Office 2007)? I have no experience with the Visual Style Builder and cannot find the 'selected item' style and the 'current item' style for ListBoxes in the Style Builder... Any help is appreciated. Thanks!

Regards,
A. Bennen.

Scroll To Appointment?

In my application, i created a button called "First Available"

When the button is pressed, I determine what is the first available time slot (based on data stored in a DB) and then create a temporary entry (green in color) into the calender that says "THIS IS THE FIRST AVAILABLE."

I would like for the calender to automatically scroll to that time slow. I know how to change the date, but I am not sure how to make the calender scroll down to view the appropriate slow.

If there would be a better method to do this, please feel free to speak up.

Thanks!

Possible cross thread issue?

We have a RadTabStrip control that has listboxes and combo boxes located on each TabItem.

The issue we are running in to is populating the BindingSources for each combo box on the RadTabStrip.TabSelected event.

On form load, we have the following code:

                            void Form1_Load(object sender, EventArgs e)         
                    {         
                        PopulateOutTabCombo();         
                        PopulateOutTabList();         
                        this.radTabStrip1.SelectedTab = tabItem2;         
                    }         
                     
                    void PopulateOutTabCombo()         
                    {         
                        DataItem2Manager dm2 = new DataItem2Manager();         
                        this.outTabComboSource.DataSource = dm2;         
                    }         
                    void PopulateOutTabList()         
                    {         
                        DataItem1Manager dm1 = new DataItem1Manager();         
                        this.outTabListSource.DataSource = dm1;         
                    }         

The routine that handles the radTabStrip1.SelectedTab event has the following code:

                            void radTabStrip1_TabSelected(object sender, Telerik.WinControls.UI.TabEventArgs args)         
                    {         
                        PopulateInTabCombo();         
                        PopulateInTabList();         
                    }         
                     
                    void PopulateInTabCombo()         
                    {         
                        DataItem2Manager dm2 = new DataItem2Manager();         
                        this.inTabComboSource.DataSource = dm2;         
                    }         
                    void PopulateInTabList()         
                    {         
                        DataItem1Manager dm1 = new DataItem1Manager();         
                        this.inTabListSource.DataSource = dm1;         
                    }         

When the SelectedTab changes to tabItem2 on the form load event, the BindingSource does not get populated with any data, even though the code is being run.

Even more interesting, if you breakpoint the code 'this.inTabComboSource.DataSource = dm2;', you can see that the BindingSource.Count = 0, BUT.... the BindingSource.DataSource property has 10 items in it!

This ONLY happens when you programmatically switch the SelectedTab. If the user clicks on the tab to switch it, it works perfect! Is there some cross thread issues going on that I am not seeing?

After the form loads, if you manually switch the tabs, the BindingSource will be populated, and you will get the items in the combo box and list box.

You can download a copy of my sample solution if you need to reproduce the issue.

Has anyone else run into this problem? If so, have you been able to solve it?

etc

Also, is it possible to have more than 1 appointment at a time per interval?

Parse and format events

Hi, I have a GridView bound to a DataTable, and I want to bind a CheckBoxColumn of my GridView to an Integer DataColumn of my DataTable. So the checked CheckBox corresponds with '2' in the Integer DataColumn, and the unchecked CheckBox corresponds with '1' in the Integer DataColumn. Is there something like parse and format events for this binding? Thanks.

Day Changed Event?

I was just curious if there was a day changed event (or something similar).

I am loading my scheduler up within the code, but I was only wanting to load the data for the selected day.

So I figured I would load the data when the user switched days on the scheduler. Am I able to do this?

Change ForeColor of selectedRow when gridviewcheckboxcolumn is set to true

Hi,

    
            private void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e) 
        
                    { 
        
                        if (sender is GridCheckBoxCellElement) 
        
                        { 
        
                            if ((bool)((GridCheckBoxCellElement)e.CellElement).Value == true) 
        
                            { 
        
                                e.CellElement.RowElement.ForeColor = Color.Red; 
        
                            } 
        
                        } 
        
                    }

But the "Value" parameter is System.dBNull. ¿why? .

Thanks,

Support for .NET 3.5 SP1 Client Profile

Hello, I would like to target the .NET 3.5 Client Profile for my solution using Telerik RadControls for WinForms. But when I build my project containing a few of the controls such as RadTabStrip, I get these kind of warnings:

Are you planning on supporting the .NET 3.5 client profile?

Flow Layout in RadPanel

Hi,

I notice the documentation for the Wrap Layout class, but cannot find a way of applying a Layout specifically to a RadPanel - I must be having a bad day, because its clearly what its there to do. I want to replace my standard WinForms FlowLayoutPanel with the visual goodness of a Rad control, and think this would be the best approach.

Has anyone managed to do it, or have another possible approach ?

Thanks
Phillip H
