[Solved] Drag and drop and dock maximized

Hello telerik,

I am about to finish a custom implementation of a feature which consists of an element from a treeview being dragged to a Docking pane.

The attached screen shot shows how it happens.

The only thing missing so far is I need to find a way to dock it maximized or expanded, as of now the usercontrol comes taking only part of the space available as default.

is there an easy way to achieve the desired behavior problematically?

Here is my code:

private void RadDocking_Drop(object sender, DragEventArgs e)

{

var data = e.Data.GetData("TreeViewDragDropOptions");

var item = ((TreeViewDragDropOptions)data).DraggedItems.First();

var splitter = ((RadDocking)sender).Items[0];

RadPaneGroup group = (RadPaneGroup)((RadSplitContainer)splitter).Items[0];

var newPane = new RadPane();

switch (((RadTreeViewItem)item).Name)

{

case "RadPdfViewer":

newPane.Content = new UserControl1();

newPane.Header = "uc1";

break;

case "RadChartview":

newPane.Content = new UserControl2();

newPane.Header = "uc2";

break;

case "RadDataFilter":

newPane.Content = new UserControl3();

newPane.Header = "uc3";

break;

}

if (newPane.Content != null)

group.AddItem(newPane, Telerik.Windows.Controls.Docking.DockPosition.Center);

}

Thank you

Docking

[Solved] Question about WizardPages in XAML Designer

Hello All,
Well, color me stupid or something, because I can figure this one out. I'm using Visual Studio 2013 and I am trying to create a wizard for my WPF application. I have created a RadWizard with a RadWiardPages collection in it, with multiple WizardPage (six to be exact) objects in the collection. However, I can ONLY see ONE of the pages in the Designer. I CANNOT switch between the pages like I can on another window where I have a standard TabControl. I would like to know how I can design subsequent pages in a wizard when I can only see one page. On the other window with a TabControl, when I select a different TabItem the designer shows that TabItem's contents. Is there a way of doing this with the RadWizard control????? It makes it very difficult to design any Wizard with multiple pages when you can't see the different pages in the designer!!!

Thanks in advance,

Possible to view WizardPages which are in the same window?

I want to be able to switch the design view from wizardpage to wizardpage. Currently It will only display the first wizardpage entered in the xaml view.

Is this currently possible? If not I guess the alternative would be to make a new page.xaml for every telerik:wizardpage then override the default navigation somehow. I could use some help finding a solution.

<telerik:RadWizard x:Name="radWizard"> <telerik:RadWizard.WizardPages> <telerik:WizardPage Name="DeployTargetPage"> <telerik:WizardPage.Content> <Grid> <TextBlock Width="80" Height="20" Margin="35,51,387.4,207.4" >Deploy target</TextBlock> <ComboBox Width="100" Height="20" Margin="35,76,367.4,182.4" > <ComboBoxItem Selected="LocalDeploySelected">Local host</ComboBoxItem> <ComboBoxItem Selected="AzureDeploySelected">Azure</ComboBoxItem> </ComboBox> </Grid> </telerik:WizardPage.Content> </telerik:WizardPage> <telerik:WizardPage Name="SetParametersPage"> <telerik:WizardPage.Content> <Grid> <TextBlock Width="100" Height="20" >Site name</TextBlock> <ListBox Grid.Column="0" Height="20" /> <TextBlock Width="100" Height="20" >Publish link</TextBlock> <ListBox Height="20" /> <TextBlock Width="100" Height="20" >User name</TextBlock> <ListBox Height="20" /> <TextBlock Width="100" Height="20" >Password</TextBlock> <ListBox Height="20" /> </Grid> </telerik:WizardPage.Content> </telerik:WizardPage>

GridView Column Aggregates

I am trying and failing to show the group totals aligned with column headers. by setting the following properties ShowGroupHeaderColumnAggregates and ShowHeaderAggregates.

This the XAML I am using - am I doing something wrong or does it just not work? The property setters seem to have no effect.

<Window x:Class="GridViewTest.MainWindow"

<Window.Resources>
<Style TargetType="t:GroupHeaderRow">
<Setter Property="ShowGroupHeaderColumnAggregates" Value="True" />
<Setter Property="ShowHeaderAggregates" Value="False" />
</Style>

Hi,

I have this code and I need to set the value of one column based on the SelectedItem (SelectedItemMyRecord) binded in the grid. The value will be set after clicking a button. Can someone help me on this?

mscorlib dll system invalidoperationexception

hi,

I'm using telerik rad map in my project with png and tiff Images,

Dynamic columns in a treelistviw

I am creating a collection of columns in the viewmodel and successfully adding the columns to the TreeListView from the code behind in an event in the viewmodel.

CodeBehind

private void Vm_OnCompletedEvent(object sender, EventArgs e)

{

try

{

tvData.Columns.Clear();

foreach (GridViewDataColumn oCol in vm.ColumnList)

{

this.tvData.Columns.Add(oCol);

}

tvData.Rebind();

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}

The XAML in the View

<telerik:RadTreeListView x:Name="tvData"

Margin="1"

ItemsSource="{Binding TreeNodeDEList}"

SelectedItem="{Binding SelectedTreeNodeDE,Mode=TwoWay}"

AutoGenerateColumns="False"

AutoExpandItems="True"

IsFilteringAllowed="False"

IsReadOnly="True"

HierarchyIndent="8"

FrozenColumnCount="1"

RowStyleSelector="{StaticResource deRowSelector}"

RowIndicatorVisibility="Collapsed">

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding ChildNodes}" />

</telerik:RadTreeListView.ChildTableDefinitions>

</telerik:RadTreeListView>

The ViewModel code to create the columns

private void CreateColumns()

{

try

{

string sUniqueName, sValuefield;

GridViewDataColumn oCol;

ColumnList = new List<GridViewDataColumn>();

oCol = new GridViewDataColumn();

oCol.HeaderCellStyle = HeaderStyle();

oCol.Width = 250;

oCol.Header = "Category/Line Item";

oCol.UniqueName = "Rootcol";

oCol.DataMemberBinding = new System.Windows.Data.Binding("NodeLabel");

oCol.HeaderTextAlignment = TextAlignment.Left;

oCol.TextAlignment = TextAlignment.Left;

ColumnList.Add(oCol);

int i = 1;

foreach (WeekNoDB oWk in lWeekNo)

{

sUniqueName = string.Format("CellLabel{0}", i.ToString().PadLeft(2, '0'));

sValuefield = string.Format("CellLabel{0}", i.ToString().PadLeft(2, '0'));

oCol = new GridViewDataColumn();

oCol.HeaderCellStyle = HeaderStyle();

oCol.Width = 40;

oCol.Header = string.Format("{0}/{1}", oWk.ToDate.DateTimeFromNull().Day, oWk.ToDate.DateTimeFromNull().Month);

oCol.UniqueName = sUniqueName;

oCol.DataMemberBinding = new System.Windows.Data.Binding(sValuefield);

oCol.HeaderTextAlignment = TextAlignment.Center;

oCol.TextAlignment = TextAlignment.Right;

ColumnList.Add(oCol);

i++;

}

if (this.OnCompletedEvent != null)

{

this.OnCompletedEvent(this, new EventArgs());

}

catch (Exception exc)

{

gUI.PopError(string.Format("{0}.{1}", this.GetType().Name, System.Reflection.MethodBase.GetCurrentMethod().Name), exc);

}

This works perfectly - ONCE

The second time i get the error

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in Telerik.Windows.Controls.GridView.dll

Additional information: DataGrid_DisplayIndexOutOfRange

Astonishingly there is little response from Google, or my foo is not working. Any ideas how to fix this problem.

ReverseGeocode

Hi,

If I want to convert a location point to an address I have to call the ReverseGeocodeAsync() method of the BingGeocodeProvider and pass a ReverseGeocodeRequest to it. However in R2 2017 this classes are deleted. And I didn’t find this classes in BingRestMapRouting.

Could you please tell me how to implement that ReverseGeocode logic in new version of telerik(R2 2017).

This is blocking us and need immediate help.

Thanx
