Hi,

I found there is a (I think) similar thread here - but the answer is "find the information in you support ticket" - which does not really help.

My problem:
I have a ComboBox in Radtabstrip.
As usual (custumer employees are used to it - me too) I try to open the CB-list by pressing ALT+DOWN.
What happens?
Tabstrip switches to another page.

I found no setting for "no keyboard nav in tabstrip" or so.

Althoug the setting should be:
Use the well know windos keys for Pagenavigation and keep away the fingers from other predifined key settings :)

What do I mean?
How do you navigate on default windows Tabpages?
CTRL+TAB forward - or CTRL+SHIFT+TAB backwards.
And whatfore ist ALT+DOWN? Yes to open a combobox list.

Anyhow - my problem - I built the app on your control and now I have to implement "default windows behaviour".

So how do I
a.) Disable ALT+DOWN on the tabcontrol so that I can use ist for Comoblist?
b.) How do I change pagenavi to CTRL+TAB (SHIFT+CTRL+TAB)

The first is most important because my customers employees use this combination very often; which means my programm is not usable at the moment for them.

Regards

Type of Row Selected

Hello,

How can I get the type of row selected/clicked in radgridview?

I'using a radgridview(master) to show data in another radgridview (detail) evertime that a user clicks in the master radgridview. This works fine when the master radgridview isn´t filtered or grouped.

When the radgridview is filtered or grouped and the user clicks in the (+) symbol to expand de row I get the following error:

System.InvalidCastException: Unable to cast object of type 'Telerik.WinControls.UI.GridViewGroupRowInfo' to type 'Telerik.WinControls.UI.GridViewDataRowInfo'.

The error is generated in the event CurrentRowChanged

How can I detect the type of row selected/clicked or disable that event to prevent this error?

Thank for your support.
LM

RadListBox values

Hi. I need to store two values in each of the items of the radlistbox. I'm trying this:

    
                Class MyItem 
        
                    Inherits Telerik.WinControls.RadItem 
        
                    Public MyShowText As String 
        
                    Public MyStrng As String 
        
                    Sub New(ByVal ShowText As String, ByVal Strng As String) 
        
                        MyBase.New() 
        
                        MyShowText = ShowText 
        
                        MyStrng = Strng 
        
                        Me.Text = MyShowText 
        
                    End Sub 
        
                End Class 
        
                ListBox1.Items.Add(New MyItem(Path.GetFileName(file_name), file_name))

But the listbox is always empty.

Can you help me?

Thanks

First Docked , then AutoHide

Hello,

I am using the DockingManager (6.0.2.0) and set two of the panels DockState-Property to AutoHide. Now the Designer cannot show the form anymore saying "This is not valid state for tabbed document container. Please first change state to Docked and then to AutoHide"

I did change the Designer Code and added the DockState-Property setting to my own Initialize method. But now every time I save the Form, the designer code gets altered back to AutoHide, which means after the next build again I cant see the from in the designer again.

Am I doing something wrong ? Whats the normal way of setting a Panel to AutoHide in the Designer.

Thanks

hierarchical grid issues

I am using the Q1 2008 beta. I have the following issues while using the grid with hierarchical on. I have 2 dataviews on the gridViewTemplate2.DataSource = dvPrior; grdPersonal.MasterGridViewTemplate.DataSource = dvPersonal;

Issues:
1) If I rebind the grid w/ the parent expanded, the parent disappears and the child records only show. If I sort it comes back, but if I click the + sign it will sometime crash. See error

System.NullReferenceException: Object reference not set to an instance of an object. at Telerik.WinControls.UI.GridRowElement.UpdateInfo() at Telerik.WinControls.UI.GridTableElement.Update(GridUINotifyAction action, GridViewRowInfo[] rowInfos) at Telerik.WinControls.UI.RadGridView.set_CurrentView(IGridView value) at Telerik.WinControls.UI.BaseGridBehavior.SetCurrentView(MouseEventArgs e) at Telerik.WinControls.UI.BaseGridBehavior.OnMouseDownLeft(MouseEventArgs e) at Telerik.WinControls.UI.BaseGridBehavior.OnMouseDown(MouseEventArgs e) at Telerik.WinControls.UI.RadGridView.OnMouseDown(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at Telerik.WinControls.RadControl.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at

2) I can't seem to create a relationship between the parent and child with more then 1 column. If I add 2 members it errors and says that a relationship already exists. If I add 2 columns in the child and parent the application crashes when I iniialize the control.

3) Speed of the hierarchical is pretty slow to first load. I have a 400 record table for child dataview and 20 record table for parent dataview and it takes ~ 20 seconds to load with the relation on 1 column. In comparison; the parent w/o the hierarchical children loads in 1 sec or less.

4) It would be nice to NOT show the + sign if there are no children or have that option to turn that feature on or off. Can this be an option?

5) There doesn't seem to be a way to control the height of the expanded out rows. If there is only 1 child row the expanded panel seems to be large. Will there be a way to autosize to the end of the last row and/or set the default height?

6) I have a hierarchical grid w/ 2 parent records. If I expand out the last parent record in the grid and then click the + to collapse it doesn't collapse and the parent disappears. If I re-sort the 2 parent records so that the orignial expanded record is not the last and expand and collapse the function works perfectly. Seems to only happen when parent record is the last in the grid.

It would be nice to get weekly or biweekly beta updates so us users could work out some of the bugs before release.

Default Sort Arrow

Hi,

I'm trying to set a default sort on a telerik gridview (Q2 2007)

    
            BindingList<Temp> tempList = new BindingList<Temp>(); 
        
            int j = 0; 
        
            for (int i = 1000; i > 0; i--) 
        
            { 
        
                 Temp temp = new Temp(); 
        
                 temp.Temp1 = i + " descending"; 
        
                 temp.Temp2 = j + " ascending"; 
        
                 tempList.Add(temp); 
        
                 j ++; 
        
            } 
        
            radGridView1.MasterGridViewTemplate 
        
                .SortExpressions.Add("Temp1", RadSortOrder.Ascending); 
        
            bindingSource1.DataSource = tempList;

The sort appears to work, however, the arrow to indicate sorting is does not show. Is there something that I can do to add this, or is the functionality non-existent?

Thanks,

David

RadTitleBar Buttons Keep Hover Images Displayed

I am running Q1 2008 SP1 of the WinForm Controls. I have created a custom theme for the RadTitleBar. The theme also includes 6 custom images for the Min, Max, and Close buttons. Three imaged for the default and 3 for mouse over, he mouse over works great for all three buttons. The problem I am having is that if I click on the “Minimized” button the form will be minimize to the task bar, when I bring the form back up the “Minimized” button is showing the mouse over image. This also happens on the max button.

I did notice the same problem in the Telerik Style Builder. If any anyone can point me in the correct direction on how to fix this please let me know. Thanks in advance!

This is how I have my images set UI Editor:

Telerik.Wincontrols.UI.RadImageButtonElement

                Image: Selected File Image1
                ImageClicked: Selected File Image 1
                ImageHovered: Selected File Image 2
