In my ribbon bar I can disable some elements on various occasions, and I would like to inform the user about the reason an element is disabled. Usually I would use a tooltip (and some extra code to enable tooltips even for disabled WinForms Controls). But ribbon bar elements are not WinForms controls, and also I don't know how to find a ribbon bar element at cursor's location. Do you have an idea how to inform the user about why the element is disabled when the user hovers the mouse over it?

Hey guys, Is there a way to show some clue on a page that have invalidated controls? 

I'm currently using error provider to show errors on controls, I've tried using it on the page but it don't have good location, and I need a generic solution because I use a generic validator to see if the controls has value.

I'm currently using 2015.1.225.40 version and sorry for bad english. Thanks in advance.

I'm not sure if someone will help me with this, considering the version. We are using radcontrols for winforms Q1 2009 SP1 (2009.1.9.414). 

I have a MDI Parent, and several mdi children. One MDI Child form with a RadGridView on it. The form works fine, and performs as expected. I use events like CellBeginEdit and CellEndEdit to make changes to the database. The gridview is bound to a BindingList<myCustomClass>. When I edit directly in the grid I update to database on CellEndEdit the entire object. something like this:

myCustomClass objToUpdate = (myCustomClass)RadGridView1.Rows[e.RowIndex].DataBoundItem;

Debug.WriteLine("id: " + objToUpdate.Id);

Debug.WriteLine("Priority: " + objToUpdate.Priority);

db.UpdateCustomClass(objToUpdate); 

 

However here is the problem:
If I do one update, change to another MDI Child form, and change back to the form in question, the objects are not updated correct. I can see in the debug that the Id property is correct, but the priority (Int32) have the old value. Since Priority is Int32, I can change with both keyboard and numeric up/down. But if I change priority using numeric up/down editor it works. If I change priority from 1 to 2 with keyboard and press Enter, the value does not change, but if I try to edit again, the numeric up/down have value 2...

If I just open the form and select a row, change back and forth, and do an update, everything works. It is just if I make a change to the datasource before changin forms the problem occurs. 

I have tried to deselect currentRow when form1 is deactivated, so that when I come back I have to select the row again, but does not work. 

clearing bindinglist og populating grid again does not work either. I have to restart the form.

 

 

Any help greatly appreciated.. :-|

     I have a RadDataFilter linked to a RadDataGrid which is functioning as desired.  I have a RadChartView (Bar Chart) that is a summary of what is being displayed in the Grid.  When I click a bar in the bar chart, I am populating the filter with a string that will filter the grid on only the rows that are related to the Bar.

Everything in this scenario is working, in that I get the filter looking correctly, based on the bar I clicked and the grid properly filtering.  The issue is that the filter item is DataFilterComboDescriptorItem and it is not displaying the correct value in the dropdown for the item specified.  It is basically displaying the last value ever selected, regardless of if I clear the filter.  

How is the value of a DataFilterComboDescriptorItem set when a RadDataFilter.Expression is manually assigned which affects that item?

Thoughts?

Here is my code:

Building the Filter Nodes Dynamically:

Private Sub SetupFilter(ByRef FilterDT As DataTable)
 
        Dim sFilterHold As String = RadDataFilter1.Expression
        RadDataFilter1.Descriptors.Clear()
        Me.RadDataFilter1.DataSource = FilterDT
        RadDataFilter1.Descriptors.Clear()
 
        Dim sSQL As String = "SELECT FilteredColumnName,DisplayText,FilterDataType FROM dbo.MAPPS_GridFilterDetail WHERE FilterHeaderId = 1 AND ActiveYN = 1"
        Dim dr As SqlDataReader = CLIB_MAPPS.Configuration.DBAccess.getSQLDataReader(sSQL)
        While dr.Read
            If dr("FilterDataType") = "DropDownList" Then
                Dim ddItem As New DataFilterComboDescriptorItem()
                ddItem.DescriptorName = dr("FilteredColumnName")
                ddItem.DescriptorType = GetType(Integer)
                ddItem.DataSource = GetTable(dr("FilteredColumnName"))
                ddItem.ValueMember = "ID"
                ddItem.DisplayMember = "Description"
                ddItem.DropDownStyle = RadDropDownStyle.DropDown
                ddItem.AutoCompleteMode = AutoCompleteMode.Suggest
                ddItem.FilterOperators.Clear()
                ddItem.FilterOperators.Add(Telerik.WinControls.Data.FilterOperator.IsEqualTo)
                ddItem.FilterOperators.Add(Telerik.WinControls.Data.FilterOperator.IsNotEqualTo)
                ddItem.Tag = dr("DisplayText")
                RadDataFilter1.Descriptors.Add(ddItem)
            Else
                Dim DescItem As New DataFilterDescriptorItem()
                DescItem.DescriptorName = dr("FilteredColumnName")
                DescItem.DescriptorType = Type.GetType(dr("FilterDataType"))
                DescItem.Tag = dr("DisplayText")
                RadDataFilter1.Descriptors.Add(DescItem)
            End If
        End While
        dr.Close()
        dr = Nothing
 
        Me.RadDataFilter1.Expression = sFilterHold
        If Me.RadDataFilter1.Expression.Length > 0 Then
            Me.ApplyFilter()
        End If
    End Sub
 
    Private Function GetTable(ByVal sColName As String) As DataTable
        Dim sSQL As String = ""
        Select Case sColName
            Case "Priority_Id"
                sSQL = "SELECT Priority_Id ID,convert(varchar(10), Priority_Id) + ' - ' + Priority_Description Description FROM Priority ORDER BY Priority_Id"
            Case "Category_Id"
                sSQL = "SELECT Category_Id ID, Cat_Description Description FROM Category ORDER BY Category_Id"
            Case "EA_Id"
                sSQL = "SELECT EA_Id ID, Adequecy_Desc Description FROM Education_Adequecy ORDER BY EA_Id"
            Case "Status"
                sSQL = "SELECT Status ID, Description Description FROM Deficiency_Assessment_Status_Lookup ORDER BY Status"
            Case "System_Id"
                sSQL = "SELECT System_Id ID, Systems_Name Description FROM Systems ORDER BY Systems_Order"
            Case "Unit_Id"
                sSQL = "SELECT Unit_Id ID, Unit Description FROM Unit_Lookup ORDER BY Unit"
        End Select
        Dim ds As DataSet = CLIB_MAPPS.Configuration.DBAccess.getDataSet(sSQL, "FilterTable")
 
        Return ds.Tables(0)
 
    End Function

 

Click Event from the Bar Chart to set the filter:

Private Sub radchrtRenoCostBySystem_SelectedPointChanged(sender As Object, args As ChartViewSelectedPointChangedEventArgs)
    If args.NewSelectedPoint IsNot Nothing Then
        Dim sSystemID As String = DirectCast(args.NewSelectedPoint.DataItem, System.Data.DataRowView).Row.ItemArray(0)
        Me.RadDataFilter1.Expression = "[System_Id] = " & sSystemID
        'THIS IS WHERE I WOULD WANT TO SET THE VALUE IN THE DROPDOWN TO MATCH THE sSystemID SELECTED
        ApplyFilter()
    End If
End Sub

I want to develop a WinForms application which is similar with Outlook. For the email list part, I use the custom item in the ListView to display the email information(From, Subject, Receive Time, Body Content). The ListView control is inside a split container(Dock Fill). So that, user can change the width of ListView. 

The problem is, when the subject or body content is very long, I don't want the item to auto size. I want the item hidden the text when overflow. When user changes the width of ListView via split container, the text can be shown more or less according to the width of ListView. It likes in the outlook, you can change the width of the email list, the body content and the subject can be automatically displayed to fit the width. How to implement this function by using ListView?

Any help or insights appreciated. This is for the WinForms library for VS2008.

When I try to create a new Telerick project, or convert an existing project, it fails. I'll paste in the error log below. 

Yes I know VS2008 is old and I should be using a newer version, but 2008 has features I really like, esp the MDI editor. 

What I've tried (suggested from Progress support folks) :

- Uninstalled, reinstalled

- Uninstalled, manually uninstalled the DLLs from the GAC, reinstalled, rebooted

Thanks for any assistance

Error log:

An error has occured while trying to create a new project.
