Hello,

I am trying to create a way to move rows up or down depending on user selection from the Context Menu.

Here are my XAML and C# code, and for some reason (still trying to figure out), the IndexOf is returning -1 =>

 

<telerik:RadGridView x:Name="gridView1" Grid.Row ="1" AutoGenerateColumns="False" Margin="0,5,0,10" FontSize="12" Deleted="OnDeletedIO" Deleting="OnDeletingIO" telerik:StyleManager.Theme="Summer" DataGridCell.GotFocus="DataGrid_CellGotFocus">
                        <telerik:RadGridView.ContextMenu>
                            <ContextMenu >
                                <MenuItem Header="MoveUp"  Click="MoveUp_click"/>
                            </ContextMenu>
                        </telerik:RadGridView.ContextMenu>
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding name}" Header="Name" IsReadOnly="False"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboGroup" DataMemberBinding="{Binding group}"  Header="Group"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboRTU" DataMemberBinding="{Binding rtu}"  Header="RTUs"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboOP" DataMemberBinding="{Binding op}"  Header="Operation"/>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding addr}" Header="Address"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboTypes2" DataMemberBinding="{Binding dataType}"  Header="Data Type"/>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding swapByte}" Header="Byte&#x0a;Swapping"
                            IsReadOnly="True">
                                
                            </telerik:GridViewDataColumn>

                        </telerik:RadGridView.Columns>

Hi,

 

I am using RadDiagram to display a list of hexagons grouped in containers. The hexagons are displayed in the order that I add them to containers,

however the containers do not respect the order they are added when using AutoLayout.

 

Is there a way to use autolayout but still respect the order the items were added? (Top left to bottom right order).

The filtering menu cuts the value whenever the values are too long for the width of the menu and I can't quite figure out why. (I attached a screenshot of one of the filtering menu)

What can I do to get the filtering menu to show the entire values?

 

Thank you for your help

My RadPolarChart represents an antenna radiation pattern. I need to draw an annotation relative to the origin. How can I do this? My radial axis is NumericRadialAxis but I cannot seem to figure out the origin value, and PolarCustomAnnotation wants polar and radial coordinates.

The attached image represents an antenna mounting image. i want to center the small ellipse around the origin. I'm using a DrawingImage in XAML to define the geometry.

Thanks.

-John.

 

 

 

Hi!

 

I am using RadDiagram where we have custom controls that show up on the mouse hover of some shapes.

When we zoom and create these custom controls, the zoom affects our custom controls as well (which has buttons and text, making them unusable)

 

I've tried to use the layouttransform to my control:

LayoutTransform="{Binding ElementName=Shape, Path=LayoutTransform.Inverse}"/>

 

But it didn't work. Any ideas?

Hello,
our company uses your controls in your project.
We have the following question:
Could Component Spreadsheet be fed with data from a xml file or a stream of data from xml file?

Dear support,

how can I implement date-dependencies in GanttView. That means

1. task2 depends on task1 (defined in "Dependencies")

2. if end-date of task1 changes for example from 31st of January to the 28th of February also the begin-date from task2 "automatically" has to change from 31st to 28th



Thanks in advance

Hello,

I'd like to add a button to the left of Minimize Button of the RadWindow for WPF. I want to create a custom control based on RadWindow. I'm not very familiar with creating custom controls. I got the control template of the RadWindow by using Blend, but I don't want to redo the whole template; I want to be able to use the RadWindow as it comes and just add that button to the title bar. What is the best way to do so?

Thanks,
LauraH

I have an RadAutoCompleteBox with a dynamic ItemSource that works some places and not others.  In the setter for the SearchText I run a search and populate the ItemSource.  In the box I'm working on now, the ItemSource's ObservableCollection is giving me "Exception thrown: 'System.ArgumentException' in System.Core.dll" when i try and add item to it. This method works many places elsewhere, and If i manually set the SearchText elsewhere the offending code runs without error. Any help would be greatly appreciated.

Here's the XAML:

<telerik:RadAutoCompleteBox 

    Grid.Column="2" Grid.Row="3"
    x:Name="AutoCompleteBoxMakeModel"
    ItemsSource="{Binding MakeModelCollection}"
    SearchText="{Binding MakeModelTerm, Mode=TwoWay}"
    SelectedItem="{Binding SelectedMakeModel, Mode=TwoWay}"
    SelectionMode="Single"
    HorizontalAlignment="Left" 
    TextSearchPath="Display"
    TextSearchMode="Contains"
    AutoCompleteMode="Suggest"
    IsDropDownOpen="{Binding IsMakeModelDropDownOpen, Mode=TwoWay}"
    DropDownItemTemplate="{StaticResource MakeModelSearchTemplate}"
    DropDownWidth="300"
    VerticalAlignment="Top" Width="275"  Height="25" Margin="0,3,0,0" >
    <telerik:StyleManager.Theme>
        <telerik:VisualStudio2013Theme/>
    </telerik:StyleManager.Theme>
</telerik:RadAutoCompleteBox>

 

And here's the offending code:

private string makeModelTerm;
public string MakeModelTerm
{
    get { return makeModelTerm; }
    set
    {
        if (makeModelTerm == value)
        {
            return;
        }
        makeModelTerm = value;
        RaisePropertyChanged("MakeModelTerm");
        if (value.Length > 2)
        {
            SearchMakeModel(value);
        }
    }
}

private void SearchMakeModel(string value)
{
    LookUpRepository er = new LookUpRepository();
    var list = er.SearchMakeModel(value);
    MakeModelCollection.Clear();
    list.ForEach(MakeModelCollection.Add); // This triggers the System.ArgumentException on each value in list
    this.IsMakeModelDropDownOpen = true;
}
