Child Grid View - How to avoid displaying a blank line at the end of the child grid

Dear All,

I have a master grid view that displays a hierarchical child. However, the child window always displays below it a blank line, supposedly I believe the place whre the horizontal scroll bar would appear, and I am trying to find a way how to get rid of it. Setting different options like horizontalscrollebar always hidden does not do the trick. Any ideas anyone?

Thank you in advance,

George

text changed event firing before the selectedvalue changed

i have a normal radcombobox (not multicolumn), and i populate it using the textchanged event , through a stored proc that searches on text entered, the stored proc and datalayer returns an custom object collection and it fills the radcomboo correctly. i cannot use the autocomplete mode as the amount of data that will eventually be in the combobox will be very cumbersome, as well as the search is not a simple text search as it searches on more than one column in the Database.
however now when i select an item in the combobox either by pressing down or by selecting an item with the mouse it then selects that item and puts the text into the radcombo.text field, however it is my understanding that the event that fires this off is the selectedvalue changed? however the text changes and txtchanged is run before selectedvaluechanged and this is causing problems for me? is this the correct order of events firing and if so how can i get around this ?

here is sample of similar code

    
               private void rcboInfo_TextChanged(object sender, EventArgs e) 
        
                    { 
        
                        List<InfoComboDetails> allInfos = controller.GetInfoBySearchString(searchstr); 
        
                        foreach (info i in allInfos) 
        
                        { 
        
                            RadComboBoxItem rcbi = new RadComboBoxItem(i.Column1 + " - " + i.colum2 , i.ID); 
        
                            rcboInfo.Items.Add(rcbi); 
        
                        } 
        
                    } 
        
             private void rcboInfo_SelectedValueChanged(object sender, EventArgs e) 
        
             { 
        
            rcboinfo2.SelectedValue = controller.GetInfo2ByInfoID((int)rcboInfo.SelectedValue).ID; 
        
            }

Problems with ShowDayHeaders/ShowHeader

Hi, I'm evaluating the RadScheduler for a project at the moment and it looks pretty good, but I need to display multiple day views (same day, different people) side by side and hide the headers.

Although the documentation is a bit sparse, I would have thought that the ShowDayHeaders, or ShowHeader on the active view would have controlled this, but it doesn't appear to work. Any hints as to how to achieve this?

                            Dim sched As New RadScheduler         
                    sched.BackColor = System.Drawing.Color.White         
                    sched.DataSource = Nothing         
                    sched.Dock = System.Windows.Forms.DockStyle.Left         
                    sched.HighlightToday = True         
                    sched.Location = New System.Drawing.Point(0, 0)         
                    sched.Name = "RadScheduler1"         
                    sched.Size = New System.Drawing.Size(200, 560)         
                    sched.TabIndex = 0         
                    sched.Text = "RadScheduler1"         
                    sched.AllowDrop = True         
                     
                     
                    Me.pnlSchedule.Controls.Add(sched)         
                     
                    Dim view As Telerik.WinControls.UI.SchedulerDayView         
                     
                    view = TryCast(sched.ActiveView, Telerik.WinControls.UI.SchedulerDayView)         
                    If view IsNot Nothing Then         
                        view.StartDate = DateTime.Today         
                        view.DayCount = 1         
                        view.ShowAllDayArea = False         
                        view.ShowDayHeaders = False         
                        view.ShowHeader = False         
                    End If         

I'm also trying to find a way to limit the displayed time range for the day, so it limits the view to WorkTime or a VisibleTime property?

One last question. I'll by trying to implement drag/drop between two+ schedule controls, I haven't started developing this yet, but I suspect that there is no underlying support for this, but it would be nice to know if it is achievable before I start playing in this area?

"Save As" Vista-like panel bar

    
            Hi, I am evaluating Telerik controls for Windows Forms, and what I want to achieve is something like the left-hand side panel on the "Save-As" dialog window when in Windows Vista (try notepad and do 'save as'). Is basically something like:  
        
            |----------------------------------|  
        
            |Favorites Links                   |  
        
            | {Content}                        |  
        
            |                                  |  
        
            |                                  |  
        
            |                                  |  
        
            |                                  |  
        
            -----------------------------------  
        
            | Folders                        ^ |  
        
            -----------------------------------  
        
            so, "Favorites" remains visible all the time (locked), and "Folders" (docked on the bottom) expand upwards without covering the whole "Favorites" area like:  
        
            |----------------------------------|  
        
            |Favorites Links                   |  
        
            | {Some Content}                   |  
        
            |                                  |  
        
            -----------------------------------  
        
            | Folders                        V |  
        
            -----------------------------------  
        
            | {Content}                        |  
        
            |                                  |  
        
            |                                  |  
        
            |                                  |  
        
            -----------------------------------  
        
            Then you click on the "V" againg and the "Folders" group docks back at the bottom again.

I will appreciate any input on this.

retrieve image from image cell

I can retrieve an image from an image cell with the following

    
            myImage = radGrid.Rows(r).Cells(c).CellElement.Image

Unfortunately this produces an error when attempting to retrieve an image from a cell that isn't currently visible on screen.

How do you retrieve an image from a cell that isn't visible?

I can retrieve the cell.value from a cell that isn't visible, but have trouble converting cell.value to an image.

Thank you for your help.

Hierarchy Child Combo Box

Has a bug been reported yet for using a combo box for children in a hierarchial grid? I wanted to allow the user the ability to change information for a child from a drop down box. When I selected the combo box, the list popped up the correct select was selected, but, as soon as I moved away from the box to another cell in the same row, the cell with the combo box was empty. If i went back to it, the new selected was still there, but as soon as I moved away from that cell, nothing appeared to the user. I went so far as to cut and paste the code from a working parent combo box and still couldn't get it to work. I have had to create a separate form now to allow the user to change this information and just display the "result' as a string in the grid on the main form. Which brings me to another problem where I have to refresh the data sources to get the updated information which then collapses the hierarchy. How do I store the which parents are not collapsed so that I can return the grid to the state the user had it? I have to update the datasources for both the child and parent or else the information is not shown propoerly.
