I am trying to do a simple recursion of folders based upon this folder structure:
Folder ID
Folder Name
Folder Parent

for example root folder has an id of 0 and parent is -1 identifying it as the root folder
Subsequent folders relate back to thier parent id.

Here is the code I got:
'Format Code Block'

Public Sub getparentfolders(ByVal parentid As String, ByVal name As String, ByVal rootnode As RadTreeNode)

DBConn =

New SqlConnection(ConfigurationManager.ConnectionStrings("db").ToString)

Dim roottable As New DataTable

Dim rootrow As DataRow

roottable = FolderAPI.GetAllFoldersByParent(parentid, DBConn)

Dim subtable As New DataTable

For Each rootrow In roottable.Rows

Dim ParentNode As New RadTreeNode

ParentNode.Text = rootrow(1).ToString

ParentNode.Value = rootrow(0).ToString

'Do I have sub folders

subtable = FolderAPI.GetAllFoldersByParent(rootrow(0).ToString, DBConn)

If subtable.Rows.Count = 0 Then

rootnode.Nodes.Add(ParentNode)

Else

name = rootrow(1).ToString

getchildfolder(rootrow(0).ToString, name, ParentNode, rootnode, childnode)

End If

FolderList.Nodes.Add(rootnode)

End Sub

Public Sub getchildfolder(ByVal parentid As String, ByVal name As String, ByVal ParentNode As RadTreeNode, ByVal rootnode As RadTreeNode, ByVal Childnode As RadTreeNode)

If Childnode.Text = "" Then Childnode = ParentNode

DBConn =

New SqlConnection(ConfigurationManager.ConnectionStrings("db").ToString)

Dim roottable As New DataTable

Dim rootrow As DataRow

roottable = FolderAPI.GetAllFoldersByParent(parentid, DBConn)

If roottable.Rows.Count < 1 Then

Try

rootnode.Nodes.Add(ParentNode)

Catch ex As Exception

Dim parentnode2 As New RadTreeNode

parentnode2.Text = name

parentnode2.Value = parentid

Dim rootnode2 As New RadTreeNode

rootnode2.Text =

"Home"

rootnode2.Value = 0

rootnode = rootnode2

rootnode.Nodes.Add(parentnode2)

End Try

End If

Dim newchild As New RadTreeNode

For Each rootrow In roottable.Rows

'Do I have more folders

name = rootrow(1).ToString

newchild.Text = name

newchild.Value = parentid

Childnode.Nodes.Add(newchild)

'getparentfolders(parentid, name, ParentNode)

getchildfolder(rootrow(0).ToString, name, ParentNode, rootnode, newchild)

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim rootnode As New RadTreeNode

rootnode.Value = -1

rootnode.Text =

"Root"

getparentfolders(

"0", "Root", rootnode)

Here is where it gets annoying, Works fine except for folders with two sub folders.
Then I get this:

Specified argument was out of the range of valid values.
Parameter name: index
Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: index

Source Error:


            Line 36:             End If
Line 37:         Next
Line 38: FolderList.Nodes.Add(rootnode)

In debugging you can see the parent folder all of a sudden has an index of 2. WTF?

Input from RadTextBox to RadPanelBar issues

Running into a few issues here. The functionality we want this application to have is quite simple. We have a "notes" control with a RadAjaxPanel that consists of a RadTextBox and also a RadPanelBar within another RadAjaxPanel. Notes that are already in the database will populate into their own RadPanelbar items when the page is loaded. The user enters some text into the RadTextBox and clicks "save." For some strange reason, once the save button is clicked - the RadPanelBar disappears and is not shown again unless the whole control is closed and reopened. Another strange issue is that every now and then, the text will not save if it is entered and the save button is clicked too quickly.

Unable to set top and left properties of the window

Hi,
I am setting Top and left properties of the ajax rad window in the following way

<radw:RadWindow runat="server" NavigateUrl="CandidateReportAdvancedOptions.aspx" ReloadOnShow="true" ID="RadWindow3" SkinsPath="~/RadControls/Window/Skins" Top="500" Left="10000" Title="Candidate Report Advanced Options" Height="250px" Width="400px" Modal="True" VisibleStatusbar="False" Behavior="Close" ></radw:RadWindow>

and I am unable to see any change in the position of the rad window with or without the left and top properties.

Am I missing anything here.

Please suggest.

Thanks in Advance.

Retreiving Edited Value From Popup Window

I have a simple RadGrid bound to a business object. When I Add or Edit with the Automatic PopUp, I can not get the new / updated value from the PopUp window.

The Grid is setup with the following:

    
                    <telerik:RadGrid ID="LocationGrid" runat="server" Skin="Web20" OnDeleteCommand="OnLocationDelete" 
        
                        OnInsertCommand="OnLocationInsert" OnItemDeleted="OnLocationItemDeleted" OnItemInserted="OnLocationItemInserted" 
        
                        OnItemUpdated="OnLocationItemUpdated" OnNeedDataSource="OnNeedDataSource"  
        
                        OnUpdateCommand="OnLocationUpdate" ShowStatusBar="True"  
        
                        AutoGenerateColumns="False" GridLines="None" onitemcommand="OnItemCommand"> 
        
                        <PagerStyle Mode="NextPrevAndNumeric" /> 
        
                        <MasterTableView EditMode="PopUp" CommandItemDisplay="Top"> 
        
                            <Columns> 
        
                                <telerik:GridBoundColumn DataField="ID" UniqueName="colID" Visible="false" DataType="System.Int32"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridBoundColumn DataField="Description" UniqueName="colDescription" HeaderText="Description"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="colDelete" HeaderText="Delete"> 
        
                                </telerik:GridButtonColumn> 
        
                                <telerik:GridButtonColumn CommandName="Edit" Text="Edit" UniqueName="colEdit" HeaderText="Edit"> 
        
                                </telerik:GridButtonColumn> 
        
                            </Columns> 
        
                            <EditFormSettings CaptionFormatString="Edit Location" /> 
        
                        </MasterTableView> 
        
                    </telerik:RadGrid>

I am binding to a simple business object with the following code:

    
                    private List<Location> LocationList  
        
                    { 
        
                        get 
        
                        { 
        
                            return Session["LocationList"] as List<Location>; 
        
                        } 
        
                        set 
        
                        { 
        
                            Session["LocationList"] = value; 
        
                        } 
        
                    } 
        
                    private void BuildInitialList() 
        
                    { 
        
                        LocationList = new List<Location> 
        
                            { 
        
                                new Location() {ID = 1, Description = "Some Location"}, 
        
                                new Location() {ID = 2, Description = "Some Other Location"}, 
        
                            }; 
        
                    } 
        
                    protected void Page_Load(object sender, EventArgs e) 
        
                    { 
        
                        if (!Page.IsPostBack) 
        
                            BuildInitialList(); 
        
                        LocationGrid.DataSource = LocationList; 
        
                        LocationGrid.DataBind(); 
        
                    }

When I click on Edit for one of the values, I am able to change the existing value for the description, but both methods for retrieving the new value in the code below return the old value:

    
            protected void OnLocationUpdate(object source, Telerik.Web.UI.GridCommandEventArgs e) 
        
            { 
        
                GridEditableItem item = e.Item as GridEditableItem; 
        
                // Description is the old value 
        
                string Description = (item["colDescription"].Controls[0] as TextBox).Text; 
        
                // values["Description"] is the old value 
        
                Dictionary<string, string> values = new Dictionary<string, string>(); 
        
                item.ExtractValues(values); 
        
            }

Any ideas?

Status[title] bar only shows when the window is minimized

Hi

Status or title bar of an open window only shows when the window is minimized.
Is this really implemented this way unlike the older versions or is there a way to achieve the same by tweaking properties and workarounds?

Please help.

Thanks

InPlace Editing

In general I am frustrated with the documentation and exmples for Telerik Rad Control especially the grid. Most examples are too trivial and explore only basic stuff but when the detail comes, I may be spending hours on trying to find the right way to solve the issue.
That is very unproductive.

Anyway, right now I am trying to solve a simple thing. I am using "InPlace" editing in the grid and a simple GridBoundColumn. When switched to the edit mode, the edit box size is much smaller the the width of my column. How do I control this in ASPX file?
