ChildViewExpanding and changing content of ChildGridView

Hello All,
I have a task to evaluate Telerik GridView, but I'm stacked with a problem.
I need to create hierarchical RadGridView, but scenario where I will bind on startup Master and Childs Templates is not good for me, because most of the data in ChildGrid will be shown only on expanding, and in my scenario getting all the data is too expensive.
So I'm trying to populate Rows collection of ChildGridView template on ChildViewExpanding event.
And here where I have a problem. After first time I expand on + I have correct content, but then I collapse, and expand again, there is no content ( and in code Rows collection is properly filled with data ).
I found some threads on forum where other have similar issues, and conclusion was that Hierarchy can't be created dynamically and updated on expanding event.

What I'm missing here, or is this as designed?
Is there workaround for this( or way to simulate same behavior), or my best choice is to bring new GridView when user click master grid.

Thanks in advance.
Regards

RE: Instructions on updating an existing project

Hi

Thanks for beta update

In instructions to set up - it states update references to new dll's

When I right clicked references in the windows project there was no ability to update

Does that mean I have to delete each existing telerik reference and create a new one or is there another automatic or manual method I could use to update them please

Serialization problem (restoring wrong sizes)

Hi there,

I have got problems regarding serialization/deserialization of docking layouts.

1.) When I adjust the width or height of an auto hidden window, this size won't be stored anyhow. If I reload the layout the size is alwas set to a default size. So the user have no chance to adjust the width or height of auto hidden windows permanently. I can reproduce this behaviour with the RadControls for WinForms example application under "RadDock-->Serialization". For me it seems that the size of an autohidden window isn't stored in the xml file at all. Am correct there? What can I do?

2.) When having a floating window the size of this window will not be restored correctly. Its size decreases everytime saving and loading the layout to xml. This behaviour can be reproduced in the sample application, too!

Please help ...

Best regards,
Oliver Bollmann

MDI Dock Manager Child Form Index

How do I determine a child form's index number located in DockManager.MdiChildren collection? In other words, I'm trying to determine what tab a child form belong's to. I tried the following code:

System.Array.IndexOf(oDockingManager.MdiChildren, oClientForm)

I only get 0 as a result, no matter which tab the form is located in. Any help would be appreciated.

Thanks,

Mitch

Implement applicationwide hotkey

I would like to run a applicationwide hotkey which enables the user to execute a specific command (eg maximizing all mdi forms) pressing alt-enter

When using this code it works:

ChordModifier1.AltModifier =

True

ChordModifier1.ControlModifier =

False

ChordModifier1.ShiftModifier =

False

Chord1.ChordModifier = ChordModifier1

Chord1.Keys =

"Alt+Y"

InputBinding1.Chord = Chord1

ClickCommand1.Name = "ActionCommand"

ClickCommand1.OwnerType =

GetType(Telerik.WinControls.RadItem)

InputBinding1.Command = ClickCommand1

InputBinding1.CommandContext =

Me.rbeWindowsMaximize

However when I use

Chord1.Keys = "Alt+Enter"

it does not work. How can I get Alt-Enter to work?
thnx

Creating a Manual Context Menu with RadMenuItems

Hi,

I am attempting to create a manual type of contextmenu for a radgroupbox. I add radiobuttons to the radgroup box, then 2 menu items, one is Add MA, the other is Remove MA. The Add MA should expand to the right and then down and show the selection of MA's to add. The remove would of course getElementAt and remove one of the radiobutton controls. Every attempt I have made the second menuitem never opens up. Code is below, any help would be apprecaited.

                            private void setup_ma()         
                    {

Unbound GridView Save to Database

I have a GridView that I populate manually using OpenFileDialog...

Dim fname As String = ""

        If (dlgImportClients.ShowDialog() = Windows.Forms.DialogResult.OK) Then
            fname = dlgImportClients.FileName
        End If

Dim TextLine As String = ""
Dim SplitLine() As String

If System.IO.File.Exists(fname) = True Then
Dim objReader As New System.IO.StreamReader(fname)

Do While objReader.Peek() <> -1
TextLine = objReader.ReadLine()

'need to add false for checkbox column
TextLine = "False," + TextLine

SplitLine = Split(TextLine, ",")

                dgvClients.ColumnCount = SplitLine.Count
                dgvClients.MasterGridViewTemplate.AllowAddNewRow = False
                dgvClients.ReadOnly = False
                dgvClients.Columns(0).IsVisible = True

                'if .RowCount = 0 then we are processing the first row
                If dgvClients.RowCount = 0 Then
                    For i = 1 To SplitLine.Count - 1
                        With dgvClients
                            .Columns(i).HeaderText = SplitLine(i).ToString
                            .Columns(i).BestFit()
                        End With
                    Next
                End If
                dgvClients.Rows.Add(SplitLine)
            Loop

            'stupid but the only way I could get the datagridview to populate correctly
            If dgvClients.RowCount > 1 Then
                dgvClients.Rows.RemoveAt(0)
            End If
        Else
            RadMessageBox.SetThemeName("Breeze")
            RadMessageBox.Show("File Does Not Exist")
        End If

I am loading the .CSV file to the GridView so that it can be reviewed, cleaned up, and then imported into Clients table within the customers database.

I'm kinda stumped as to the best way to get the data in the GridView into the database. Could just be a brain fart or I may be going about this totally wrong. Any insight would be greatly appreciated.
