Different context menus in tree and treenodes

Hi Telerik Team,

We are having some problems with context menus in a radtreeview. I'll try to explain myself. We want to have two different context menus: one in the tree nodes and another different one in the tree view. That's because we want to have actions performed on a tree node (copy, paste, rename...), and different actions performed on the tree (add new nodes to tree.Nodes).

We don't want to have a root node at tree.Nodes where the rest of nodes hang, so that's what we've done so far:

We have a treeview. With a ContextMenuManager we add a context menu to the treeview ('treeviewContextMenu').

    
               this.radContextMenuManager1.SetRadContextMenu(this.treeView1,this.radContextMenuTree);

Programmaticaly we add nodes to the tree, and we add a different contextmenu to the nodes:

    
            RadTreeNode node = new RadTreeNode(); 
        
            // fill more node properties 
        
            node.ContextMenu = radContextMenuNodes.DropDown;

At first we thought it worked but now we want to use this on a different tree where the nodes context menu has only one option while the tree one has many. And now we realized that both context menu are showing! Nodes context menu above tree context menu.

What are we doing wrong? Is there a way to do what we need? Could you help us, please?

We are using Q3 2008 version.

Thanks in advance.

Teba.

Visual Bugs in a Ribbon Form

Hello. I have used a RadRibbonForm and dropped a Windows7Theme on it. I explicitly specified the theme name on the controls (RibbonBar, StatusStrip). The Visual Studio IDE shows me the correct Office 2010-like ribbon interface. How ever, upon running on my Windows 7 x64 machine, The rendered form look somewhat different.

Please see attached image.

Also, I'm tired of specifying the theme on every element. I'm using Visual Inheritance and my Base form has an instance of Windows7Theme element dropped on it with it's modifiers being Private. All forms inheriting the Base Form are rendering with Windows7 theme but all elements on the form(s) are not. I have asked this question here as well.

Please help me out, kindly.

Master-Detail (Expandable Rows)

I'm attempting to bind a Grid (programmatic-approach) through LINQ. Here is the scenario: I have a table of clients. Every client has branches and coordinators. They have more collections but I don't want to expose them. I want to show the clients in a grid with different filtering criteria. For every client, the row expands to two tabs: Branches and Coordinators

The sub rows in the Branches View and Coordinator View must NOT be further expandable.

I want to select the columns to be shown in the Branches and Coordinators Details View.

I have tried these two approached with no success:

RadGridViewSearch.DataSource = from pharms in DbContext.Pharmacies

where pharms.IsActive && pharms.Branches.Count > 0

orderby pharms.Name

select new {

pharms.OID,

pharms.Name,

pharms.PhoneNumber,

AddressInfo = String.Format("{0} {1} {2} {3}",

pharms.Contact.Addresses.FirstOrDefault().HouseNumber ??

String.Empty,

pharms.Contact.Addresses.FirstOrDefault().Street ??

String.Empty,

pharms.Contact.Addresses.FirstOrDefault().Area ??

String.Empty,

pharms.Contact.Addresses.FirstOrDefault().PostCode ??

String.Empty),

CityName = pharms.Contact.Addresses.FirstOrDefault().City.Name,

pharms.Branches,

pharms.PharmacyCoordinators

};

RadGridViewSearch.DataSource = from pharms in DbContext.Pharmacies

from branches in pharms.Branches.DefaultIfEmpty()

from coords in pharms.PharmacyCoordinators.DefaultIfEmpty()

where pharms.IsActive && pharms.Branches.Count > 0 && pharms.PharmacyCoordinators.Count > 0

orderby pharms.Name

select new {

ClientOID = pharms.OID,

ClientName = pharms.Name,

ClientPhoneNumber = pharms.PhoneNumber,

ClientAddressInfo = string.Format("{0} {1} {2} {3}",

pharms.Contact.Addresses.FirstOrDefault().HouseNumber ??

string.Empty,

pharms.Contact.Addresses.FirstOrDefault().Street ??

string.Empty,

pharms.Contact.Addresses.FirstOrDefault().Area ??

string.Empty,

pharms.Contact.Addresses.FirstOrDefault().PostCode ??

string.Empty),

ClientCityName = pharms.Contact.Addresses.FirstOrDefault().City.Name,

BranchOID = branches.OID,

BranchName = branches.BranchNumber,

BranchPhoneNumber = branches.PhoneNumber,

BranchAddressInfo = String.Format("{0} {1} {2} {3}",

branches.Contact.Addresses.FirstOrDefault().HouseNumber ??

String.Empty,

branches.Contact.Addresses.FirstOrDefault().Street ??

String.Empty,

branches.Contact.Addresses.FirstOrDefault().Area ??

String.Empty,

branches.Contact.Addresses.FirstOrDefault().PostCode ??

String.Empty),

BranchCityName = branches.Contact.Addresses.FirstOrDefault().City.Name,

CoordinatorOID = coords.OID,

CoordinatorName = coords.FirstName + " " + coords.LastName,

CoordinatorCell = coords.MobileNumber,

CoordinatorEmail = coords.Email

};

The first one produces the desired result in short time but the results are uncontrolled. I cant prevent deep-drilling, Tabs names, and Columns. The second one produces liners results and hence that fails as well. And the second one takes massive time...

Can anyone guide on this?

Objective: Create Master details grid with full control of all Column Headers (Master + Detail), All details Tabs Names

Hello my friends,

Is there a nice way for letting the user to set default values for some of the columns for new row? (when adding new row it will contains the default values (template row or something like this))

Another little question: can you tell me where i can find winforms grid view advanced demos? most of the demos i saw in the telerik tv are in high level.

Thank you very much!

accessing active document grid in RadDock

Hello,

I was wondering how I can go about interacting with the a radgridview on an active documentwindow. Here is my scenario:

1. Using a RadRibon form
2. Using RadDock with Autodetect MDI form
3 toolwindow with TreeView.
4. TreeView is filled from a dataset / datatable which is filled from SQL database

each node of the tree view has a unique SQL statement associated with it. This is my code when doubleclicking the node:

Private Sub TV_Reports_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TV_Reports.MouseDoubleClick

Try

Dim filter As String = "ID='" & TV_Reports.SelectedNode.Tag.ToString & "'"

For Each row As DataRow In ds.Tables("TreeView_Reports").Select(filter)

If row("Menu_Type").ToString = "Report" Then

Me.SqlReportStr = row("Sql_Query")

Me.Parent_StatusStripLabel.Text = "Running report: " & row("Name")

Me.Parent_StatusStrip.Update()

Me.Parent_StatusStrip.Refresh()

Dim frm As New Form_Report

frm.Text = "Report: " & row("Name")

frm.MdiParent = Me

frm.FormBorderStyle = Windows.Forms.FormBorderStyle.Sizable

frm.Dock = DockStyle.Fill

frm.WindowState = FormWindowState.Maximized

frm.Show()

End If

Next

Catch ex As Exception

End Try

End Sub

the public variable SqlreportStr is set so the Report form can read it and run the query

Public Class Form_Report

Dim ds As New DataSet

Dim DT_Report_Results As New DataTable("ReportResults")

Dim SqlReportStr As String = Nothing

Dim jobcount As Integer = 0

Private Sub Form_Report_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed

ds.Clear()

ds.Dispose()

Me.Dispose()

Me.Cursor = Cursors.Default

GC.Collect()

GC.WaitForPendingFinalizers()

GC.WaitForFullGCComplete()

GC.WaitForFullGCApproach()

GC.Collect()

End Sub

Private Sub Form_Report_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

ds.Tables.Add(DT_Report_Results)

SqlReportStr = Form_Parent.SqlReportStr

Me.Cursor = Cursors.WaitCursor

Dim Search_Worker As New BackgroundWorker

jobcount += 1

AddHandler Search_Worker.DoWork, New DoWorkEventHandler(AddressOf StartReportFill)

AddHandler Search_Worker.RunWorkerCompleted, _

New RunWorkerCompletedEventHandler(AddressOf Search_worker_RunWorkerCompleted)

Search_Worker.RunWorkerAsync()

Search_Worker.Dispose()

End Sub

Private Sub StartReportFill(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs)

FillSqlDs("ReportResults", SqlReportStr)

End Sub

Private Sub Search_worker_RunWorkerCompleted(ByVal sender As Object, ByVal e As RunWorkerCompletedEventArgs)

jobcount -= 1

GridLayout()

Me.Cursor = Cursors.Default

End Sub

Private Sub GridLayout()

Try

GV_Reports.DataSource = ds

GV_Reports.DataMember = "ReportResults"

Catch ex As Exception

MsgBox(ex.Message)

End Try

GV_Reports.Columns("Sys_ID").IsVisible = False

Form_Parent.Parent_StatusStripLabel.Text = "Ready!"

Form_Parent.Parent_StatusStrip.Update()

Form_Parent.Parent_StatusStrip.Refresh()

End Sub

Private Sub FillSqlDs(ByVal tbl As String, ByVal qry As String)

If Form_Parent.MyConnection.State = ConnectionState.Closed Then

Form_Parent.MyConnection.Open()

End If

'Using Form_Parent.MyConnection

Dim Dadapter As New SqlDataAdapter

Using Dadapter

Try

Dadapter.SelectCommand = New SqlCommand(qry, Form_Parent.MyConnection)

Dadapter.Fill(ds, tbl)

Catch ex As Exception

MsgBox(ex.Message)

End Try

End Using

End Sub

End Class

The problem that I have is that this form could be open several times at once displaying different data as the SQL queries are differnet. Also looking at the name of the form it comes accorss as Form_Report1, Form_report2 etc depending on what instance of the form that it is.

I am looking to be able to do the following with the girds:
1. export to excel
2. process each row of the grids in order to make other database changes.

if some one could point me to how I could exactly about interacting with the gridview i would greatly appreciate it.

thanks!
