Hi,

Having spent way too long on this, what has to be done to switch autogenerated columns OFF on the GridView? The property seems to be getting ignored, whether I set it in codebehind or in the propertymanager.

I've defined my columns through the collection in Vis Studio, and then call

SqlConnection cn = new SqlConnection(feedsSvr);
            cn.Open();
            SqlCommand cmd = new SqlCommand("ASP_GetDeltas", cn);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@FeedGUID", feedGUID);
            SqlDataReader dr = cmd.ExecuteReader();
            radGridView1.MasterGridViewTemplate.AutoGenerateColumns = false;
            radGridView1.MasterGridViewTemplate.LoadFrom(dr);

Thanks for your help!!

Binding to Hierarchical Data Programmatically

I have setup a Hierarchical Grid programmatically basically following the example in the Documentation. Now I need to update some Cells in the ChildGridView programmatically and assumed I can update the cell info with the following:

    
            '-- The ChildGridView has already been populated with data  
        
            Dim cTemplate As GridViewTemplate = GridViewPricing.MasterGridViewTemplate.ChildGridViewTemplates(0)  
        
            'The following throws an error : 
        
            'Object reference not set to an instance of an object.  
        
            cTemplate.Rows(0).Cells(1).Value="somedata"

The above throws the Object reference not set to an instance of an object error. In fact accessing any of the Cells methods or properties throws the Object Not set to an instance of an object.

Any help greatly appreicated.

Making Ribbon/Toolbar Optional

Hi,
I'm evaluating your WinForms control suite and was wondering if I can build an application where the user can choose between having a ribbon or a menu/toolbar application window. If so, how can I switch between those modes programmatically? Some other control vendors just require to drop the ribbon control onto a standard form to make it a ribbon form. When I then hide the ribbon control and show the menu/toolbar, I'm basically back in standard (menu/toolbar) mode again. Is something like that possible using Telerik?

DropDown or ComboBox for filtering a gridview

I have been looking all weekend for this solution but cant seem to figure it out. I have a sql database, very small and simple. It is basically is a support database for taking service requests. (just a training for myself) I have a database view that i'm using to bring the information into my winform project.

I'm trying to figure out the best way to filter a gridview using the dropdown.

1. Is it possible to populate a RadDropDownButton with the Technician Name items from a sql database and then filter the records in a gridview?
2. Is it better to use a combobox although the dropdown seems to look cooler?

So I have a radform, drop a raddropdown and a gridview on the form... I can get the gridview to display records, I can get a combobox to show the technicians but I can only get the dropdown to display the first technician.

I have not been able to get any of the dropdowns or combobox's to filter the gridview.. anybody have any simple solutions that I may be missing?

I have tried several different ways, one such as this:

    
            Public Class RadForm1  
        
                Private Sub RadForm1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load  
        
                    'TODO: This line of code loads data into the 'WODataset.WorkOrderMain' table. You can move, or remove it, as needed.  
        
                    Me.WorkOrderMainTableAdapter.Fill(Me.WODataset.WorkOrderMain)  
        
                    RadDropDownButton1.Items.Add(WODataset.WorkOrderMain.techFullNameColumn)  
        
                    RadComboBox1.Items.Add(WODataset.WorkOrderMain.techFullNameColumn)  
        
                End Sub 
        
            End Class

Both of these do not work for populating the fields...

Please excuse my noviceness... :)

BackColor of TabStrip

Hi,

I am having problems with setting the BackColor of the RadTabStrip Control. I have tried setting the BackColor of the control and it has no effect on a standard window.

I am trying to use this on a RadWindow.

I have tried Editing the UI Elements too and this has had little effect.

Do I need to create a Theme just to change the BackColor of the tab strip? If so when I create the theme in the new editor it seems to be totally blank and default (almost like a wire frame) Seems to be totally different to how the 2009 build works.

Please can someone offer some assistance. I would like to make the general back colour of the control and tabs white.

Kind regards
Neil

[Solved] Problem combining context menus

Hello,

there is a strange problem adding some RadContextMenuItems to the context menu from a GridView.

It works fine to catch the ContextMenuOpening event and add the Items (3 Separators and 4 MenuItems in this case) from a RadContextMenu on the form by the following code snippet:

    
                    Private Sub DataGridViewMain_ContextMenuOpening(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.ContextMenuOpeningEventArgs) Handles DataGridViewMain.ContextMenuOpening  
        
                        Try 
        
                            e.ContextMenu.Items.AddRange(RadContextMenuGridView.Items)  
        
                        Catch 
        
                        End Try 
        
                    End Sub

But sometimes after 3, sometimes after 10 or later tries the AddRange throws an exception:
"Das angegebene Element kann nicht entfernt werden, da es nicht in der Auflistung gefunden wurde."

The context menu shows without the custom added items. The problem is not the contextmenu but the items collection that should be added. It seems that it is blocked by the old context menu instance and not released properly.
I could not workaround this. I have to create a new instance of the form to get it work again.
Is there a fix for this or is it possible to duplicate the Item Collection so that there is no blocking?

Thank you!

Bernd
