Hi,

As I would like to display rich, structured information with validation errors, in my application calls to INotifyDataErrorInfo.GetErrors don't return strings but complex objects. For example, there is a severity level that would need to affect the colors (from orange to darker red).

It easily works everywhere, except on the RadGridView.

I've been trying to replace the GridViewValidationToolTipTemplate with something that does not assume errors to be simple strings. I've tried setting the ToolTip.Content in other templates to Validation.Errors (the original errors) instead of Errors (which is a list of strings), but that just brings a list of duplicated entries at row level (GridViewRowTemplate), or no entry at all on cell level (GridViewCellTemplate).

Am I missing something? What do you suggest?

Thanks

Hey

I have some problem with Kendo.Grid()

I wanna add filter for some column value then is NULL.

Code here:

x.Ajax().Read(r => r.Action("DataSource", "SRV_Service", new { area = "SRV" }))
.Filter(f => f.Add(s => s.PID).IsEqualTo((Guid?)null))

Datasource when i use null value filter.

https://resimyukle.xyz/resim/KU48JA

 

MVC Enums for filter operators

    public enum FilterOperator
    {
        IsLessThan = 0,
        IsLessThanOrEqualTo = 1,
        IsEqualTo = 2,
        IsNotEqualTo = 3,
        IsGreaterThanOrEqualTo = 4,
        IsGreaterThan = 5,
        StartsWith = 6,
        EndsWith = 7,
        Contains = 8,
        IsContainedIn = 9,
        DoesNotContain = 10
    }

 

And your "Operator used in FilterDescriptor" keys has IsNull operator
http://docs.telerik.com/aspnet-mvc/api/Kendo.Mvc/FilterOperator

How can i do append IsNull operator on Kendo.Mvc.FilterDescriptor ?

Please help me

Hi!

Last two days I have been recording tests on Web types and Wpf types separately

Seems like 'random name generator' is working fine in Web Type test. But is it possible to use random  ‘DataBindVariableName’ from Web types test to Wpf Type test?

Thanking you!

Kind Regards

Hi!

I have been using Test Studio in 2 days, so far Its working fine on WPF project. But I get into a problem. In our WPF project, we have a part web site for login. Seems like teststudio doesn’t recognize whatever happends inside the red markings (see the image)  as that is website part in our WPF project.

1. Is there any way around this problem?

2. I suppose I also need to login first to run other testes in Wpf project. Or Can I somehow connect to running Wpf Application to execute other recorded tests without login part.

Hi Every Body…

I use RadRichTextBox control, and my requirement is to add border to every page in the document, like that shown in the attached image.

As RadRichTextBox control doesn't support adding shapes, I tried using DecorationUILayerBase, but unfortunately I couldn't use it with the headers (to achieve my requirement).

So I tried another technique utilizing InlineUiContaineers, where I created the required structure (including the require border) and added them to a Grid control, then adding that Grid to an instance of InlineUIContainer class, and adding that instance to the header section of an instance of RadDocument class, and finally setting that instance to the Document property of my RadRichTextBox control.

This solution worked for the header of the first page only, but as the user continues writing and reaching end of this first page and new page is added the following error is thrown:
"Specified element is already the logical child of another element. Disconnect it first."

My code snippet is as the following:

Me.radRichTextBox.Document = CreateDocumentWithCustomHeader()
Public Function CreateDocumentWithCustomHeader() As RadDocument
            Dim doc As New RadDocument()
            doc.LayoutMode = DocumentLayoutMode.Paged

            Dim headerDoc As New RadDocument()
            Dim hSection As New Section()
            headerDoc.Sections.Add(hSection)
            headerDoc.SectionDefaultPageMargin = New Telerik.Windows.Documents.Layout.Padding(5, 5, 5, 5)

            Dim hparagraph As New Paragraph()
            hSection.Blocks.Add(hparagraph)

            Dim grid As New Grid
            Dim column1 As New ColumnDefinitionWith {.Width = NewGridLength(150)}
            Dim column2 As New ColumnDefinitionWith {.Width = NewGridLength(0, GridUnitType.Star)}
            Dim column3 As New ColumnDefinitionWith {.Width = NewGridLength(150)}
            grid.ColumnDefinitions.Add(column1)
            grid.ColumnDefinitions.Add(column2)
            grid.ColumnDefinitions.Add(column3)
            Dim MinistryImage As New Image
            MinistryImage.Source = BitmapManager.CreateBitmapImage("pack://application:,,,/Images/ Logo1.png", 150)
            Dim LogoImage As New Image
            LogoImage.Source = BitmapManager.CreateBitmapImage("pack://application:,,,/Images/Logo2.png", 150)
            grid.SetColumn(LogoImage, 0)
            grid.SetRow(LogoImage, 0)
            grid.SetColumn(MinistryImage, 2)
            grid.SetRow(MinistryImage, 0)
            grid.Children.Add(LogoImage)
            grid.Children.Add(MinistryImage)
            Dim border As New Controls.BorderWith {.BorderThickness = New Thickness(4), .CornerRadius = New CornerRadius(5), .BorderBrush = New SolidColorBrush(Colors.Black)}
            grid.SetColumn(border, 0)
            grid.SetRow(border, 0)
            grid.SetColumnSpan(border, 3)
            grid.Children.Add(border)
            border.HorizontalAlignment = Windows.HorizontalAlignment.Stretch
            border.VerticalAlignment = Windows.VerticalAlignment.Stretch
            border.Margin = New Thickness(5, 5, 5, -500)

            grid.HorizontalAlignment = Windows.HorizontalAlignment.Stretch
            grid.VerticalAlignment = Windows.VerticalAlignment.Stretch

            Dim container As New InlineUIContainer()
            container.UiElement = grid
            container.Height = 150
            container.Width = 700
            hparagraph.Inlines.Add(container)

            Dim header As New Header()
            header.Body = headerDoc

            Dim section As New Section()
            section.Headers.Default = header
            doc.Sections.Add(section)
            doc.SectionDefaultPageMargin = New Telerik.Windows.Documents.Layout.Padding(10, 10, 10, 10)

            Return doc
        End Function

                                                    IsReadOnly="True"  CellStyle="{StaticResource cellStyleTemplate}"
                                                    DataMemberBinding="{Binding DataContext,RelativeSource={RelativeSource Self}  ,Converter={StaticResource NodeToDisplayNameConverter}}"  >

   </telerik:RadTreeListView.Columns>

Hello,

 

I'm using Telerik 2016.3.1024.45

I figure out how to save the layout with your documentation and I have now the xml of the layout

But when I tried to use LoadFromXmlString with the xml it did nothing and the layout stays empty

 

So I thought that my xml wasn't good and I took the one from your example and it didn't work either.

 

Here the xml I tried to load (it's your sample)

<?xml version="1.0" encoding="utf-8"?>
<RadLayoutControl Type="Telerik.Windows.Controls.RadLayoutControl" Width="NaN" Height="NaN" MinWidth="0" MinHeight="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" SerializationId="myLayoutControlID" Orientation="Horizontal" IsAutoGenerated="false" IsInEditMode="false">
  <Items>
    <Button Type="System.Windows.Controls.Button" Width="NaN" Height="NaN" MinWidth="0" MinHeight="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" SerializationId="buttonID_1" />
    <Border Type="System.Windows.Controls.Border" Width="NaN" Height="NaN" MinWidth="0" MinHeight="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" SerializationId="buttonID_2" />
    <LayoutControlGroup Type="Telerik.Windows.Controls.LayoutControlGroup" Width="NaN" Height="NaN" MinWidth="0" MinHeight="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" SerializationId="layoutGroup_1" Orientation="Vertical" IsAutoGenerated="false">
      <Items>
        <TextBlock Type="System.Windows.Controls.TextBlock" Width="NaN" Height="NaN" MinWidth="0" MinHeight="0" HorizontalAlignment="Stretch" VerticalAlignment="Center" SerializationId="txtBlock_1" />
        <LayoutControlGroup Type="Telerik.Windows.Controls.LayoutControlGroup" Width="NaN" Height="NaN" MinWidth="0" MinHeight="0" HorizontalAlignment="Stretch" VerticalAlignment="Center" SerializationId="layoutGroup_2" Orientation="Vertical" IsAutoGenerated="false">
          <Items>
            <TextBlock Type="System.Windows.Controls.TextBlock" Width="NaN" Height="NaN" MinWidth="0" MinHeight="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" SerializationId="txtBlock_2" />
          </Items>
        </LayoutControlGroup>
      </Items>
    </LayoutControlGroup>
  </Items>
</RadLayoutControl>

 

And I use this to load the xml :

LayoutControl.LoadFromXmlString(@"<xml_here>");

 

Can you help me please ?

 

Thank You

Hervouet Thomas

Hello,
I've encountered a small bug with gridview rendering when using programmatic grouping.  I've got a gridview that does not display the group panel.  Instead, the user is given the option to group by a single predefined column by clicking a checkbox.  The handlers for the checkbox contain the following simple code:
private void cbxGroupByRegion_Checked(object sender, RoutedEventArgs e)
{
    RadGridView grdView = this.MyGrid;
    
    grdView.GridLinesVisibility = GridLinesVisibility.None;
    grdView.GroupDescriptors.Add(new ColumnGroupDescriptor()
    {
        Column = grdView.Columns["Region"],
        SortDirection = ListSortDirection.Ascending
    });
    grdView.ExpandAllGroups();
}
 
private void cbxGroupByRegion_Unchecked(object sender, RoutedEventArgs e)
{
    RadGridView grdView = this.MyGrid;
     
    grdView.GridLinesVisibility = GridLinesVisibility.Horizontal;
    grdView.GroupDescriptors.Clear();
}

The first time the grid is loaded, it is grouped by default and all rows display correctly.  However, on subsequent groupings, i.e., when unchecking then re-checking the checkbox, the gridview is only partly-filled with rows leaving a blank space at the bottom.  Once the user starts to scroll, the remaining rows suddenly appear.  Has anyone else encountered this?

Thanks..
