[Solved] Spinner editor step configuration

Hello.

I would like to know how to configure the spinner's step value properly in a GridView. I need the spinner to move the values by 0.01 instead of 1. The demo application and a forum search didn't solve the problem.

Closest I have come to is this code, but it doesn't work:

private void radGridViewBase_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)

{

var editor = this.radGridViewBase.ActiveEditor as GridSpinEditor;

if (editor != null)

{

editor.Step = 0.01M;

}

Thanks
Philippe

RadPageView Tabs and Pages

1) Is it possible to create tabs like they are shown in the picture with the RadPageView?

2) How would one create a single tab visually, and then make an exact copy programatically when new user's data needs to be displayed on new tab?

Thanks for any help with this.

Delete button in gridView

Hello,
I would like to have in my gridView a delete button(no commandButton) for each row added.
When i clicked on one of this buttons, i would like the corresponding row to be deleted.

This is what it does:
ICreate the button on cellFormatting and add an eventHandler

    
             Private Sub GridViewPrepack_CellFormatting(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles GridViewPrepack.CellFormatting 
        
                      If Not (e.CellElement.Children.Count > 0) Then  
        
                                Dim myButton As New RadButtonElement 
        
                                'Display style of the Image 
        
                                if  CType(e.CellElement.ColumnInfo,GridViewDataColumn).FieldName = "Delete" 
        
                                        AddHandler myButton.Click, AddressOf DeleteButton_Click 
        
                                        'add the button to the cell 
        
                                        e.CellElement.Children.Add(myButton) 
        
                            End If 
        
                        End If 
        
                End Sub

Now, i would like the row to be deleted when the delete button is clicked, but i don't know how.
I tried this, but it doesn't delete the right row

    
             Private Sub DeleteButton_Click(ByVal sender As Object, ByVal e As EventArgs) 
        
                    GridViewPrepack.Rows.Remove(GridViewPrepack.CurrentRow) 
        
                End Sub

.
can you help me?
Thank you

[Solved] ShowParentGroupSummaries don't update

Dear Support,

We use RadGridView with Summaries rows and Parent Summaries rows. On loading all sum are correct. But when the user change a value in the grid, the summaries are updated but not the parent summaries rows.

I attached pictures showing the problem. AfterLoad is the gris after the form is loaded, and afterChange is the gris when I change the value of the first row from 75 to 65. Top Summaries and group summaries have updated but not the parent summaries.

Please advise,
Nadia

DropDownList size/length/displayed item count (Solution)

Hello,

I looked sometimes for a solution to change the count of items displayed in the Popup of the RadDropDownListEditorElement.

My solution now is:

Use of EditorRequired event from RadPropertyGrid, Setting the editor to RadDropDownListEditor. Getting the EditorElement as RadDropDownListEditorElement and define the MinSize of Popup as follows:

RadDropDownListEditor editor = new RadDropDownListEditor();

RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;

element.Popup.MinimumSize = new System.Drawing.Size(element.Popup.MinimumSize.Width,

element.ItemHeight * 10);

editor.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

e.Editor = editor;

where as 10 ist the count of items to be displayed.

Regards from Leipzig
