[Solved] Show entire layer at certain zoom range

Hi,

I am using informationlayer and visualization layer to render my data. I am also using PolygonData to create my shapes. Here i want to hide my entire layer at certain zoom level. I have used below mentioned function but it is not working properly on entire layer. If i use it for a single label for example then it properly hide and show this label.

I am using this

MapLayer.SetZoomRange(myLayer, new ZoomRange(13, 18));

I am also not able to use this for my individual item which is PolygonData because of DepedencyObject.

Please let me know if i am getting something wrong or can anyone provide any alternate solution to show entire layer at certain zoomrange.

Thanks

How can I get along with bilingual headers (RadGridView)?

Hi there,

In my WPF project I'm using two RESX files in order to keep both english and spanish languages, freely chosen for the user

When I assign my SQL view on ItemsSource I get twice the name of the headers (logically, I get each header from V_Clientes2 object and then get each header in Columns collection.. For example: Header="{Resx RadGridViewCustomers_Nombre}")

I do not know how can I fix that... it is not acceptable at all, 'cause the user see "Name" and "Nombre" at the same time instead to see just one of them:

XAML:

<telerik:RadGridView x:Name="dgvClientes" ItemsSource="{Binding V_Clientes2}" HorizontalAlignment="Left"
           Margin="10,44,0,-45" VerticalAlignment="Top" Height="531"
           Width="469" ColumnWidth="SizeToCells" PreviewMouseDoubleClick="dgvClientes_PreviewMouseDoubleClick" Grid.ColumnSpan="2" Grid.RowSpan="3">

            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Tipo}" Header="{Resx RadGridViewCustomers_Tipo}" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Documento}" Header="{Resx RadGridViewCustomers_Doc}" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Nombre}" Header="{Resx RadGridViewCustomers_Nombre}" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Apellido1}" Header="{Resx RadGridViewCustomers_PrimerApellido}" />

            </telerik:RadGridView.Columns>

Find attached one image where you can see this problem.

Thanks in advance for your time and advices,

[Solved] Columns overlapping on DateTimeContinuousAxis

I'm creating a column chart with the x axis as a DateTimeContinuousAxis. Once the date range reaches sufficient length, the column widths do not get any smaller. Instead, they start overlapping each other. In my case, I have a about 85 points over a period of about 8 months with the axis MajorStepUnit set to Days. You can see in the first attachment, a screenshot of the chart where the column backgrounds are blue and the borders are red. My expectation is that the column width should shrink as more columns are added & that there should be no overlapping. Any guidance here would be appreciated. Thanks - Mitch.

Below are the xaml and code behind for creating the attached screenshot (I can send the project if desired):

Does form have validation errors?

I have a user control that contains a RadDataForm and a button.

The button is bound to a custom command that has xxx_CanExecute() and xxx_Executed() methods defined.

I want xxx_CanExecute() to set e.CanExecute to false, if the form has any validation errors. I'm getting the user control passed as sender, and from that I can get a reference to the RadDataForm. But I can't for the life of me figure out how to tell if the form has any validation errors. In the debugger I can see a validationErrors collection on the form, but that seems to be private. ValidateItem() always returns true, regardless.

Seems to me that I'm missing something simple. Can someone point me in the right direction?

Prevent from removing a node after a drop

Hi,

I upgraded from version 2012.3.1129.40 to 2013.3.1204.40.
With this new version I didn't find how to prevent from removing a node after drag & drop.
In the older version I was able to do it with:

public MyView()

{

InitializeComponent();

this.m_cellTreeView.PreviewDragEnded += this.OnPreviewDragEnded;

}

private void OnPreviewDragEnded(object sender, RadTreeViewDragEndedEventArgs e)

{

e.Handled = true;

}

With the new version, I'm using your recommendations: I use the DragDropManager class only, I set the DragDropExecutionMode to New but the PreviewDragEnded handler is not called anymore and the event PreviewDragEnded is marked as deprecated.
What is the best way to do this ?

Thanks,

Floating License?

Hi,

In the purchase section it says:

1 License for a single-named user.

In the license agreement it says:
1.2 Scope of Use. The Software is licensed, not sold, on a per-seat basis. You may only allow the number of individuals in Your organization to use the Software that corresponds to the maximum number of License seats You have purchased from Telerik hereunder. This means that at any given time, the number of individuals authorized to use the Software under the License (each a “Licensed Developer”) cannot exceed the number of License seats that You have purchased from Telerik and for which You have paid Telerik all applicable License Fees pursuant to this Agreement. The Software is in “use” on a computer when it is loaded into temporary memory (i.e. RAM) or installed into permanent memory (e.g. hard disk or other storage device) of that computer for development purposes. Your Licensed Developers may install the Software on multiple machines, so long as the Software is not being used simultaneously for development purposes at any given time by more Licensed Developers than You have License seats...

The first seems to mean that if someone takes over GUI development in a project, we need a new license, the second seems to imply it's like a floating license and only the number of users, no matter who they are, must not exceed the number of licenses.

Which is it?

Treeview column

Hi,
I would like to create a new RadGridViewColumn similar to GridViewComboBoxColumn.
The new column should contains a TreeView inside the dropdown to show the ItemsSource in hierarchical mode.
Is it possible to obtain this? Can you post me an example?

Thanks.

Open a child window from tile view item

Hello;

Is it possible to open a child window from a tile view item. I have defined a button in the normal view, then tried to bind the click to a command that will open a child window. I tried in different ways : using event, using showDialog but seems not working from the tileview item. It worked fine from a normal WPF application.

Please let me know if it is possible. I spend the whole trying but not results.
FYI, I use MVVM & WPF

Thanks for your support
