Hi

I have a question on using the CellEditTemplate which has a TextBox in RadGridView.

I have a RadGridView, one of its columns is created like this in cs file:

gvColumn = new GridViewDataColumn();
gvColumn.CellEditTemplate = (DataTemplate)grid.TryFindResource("TextBoxEditTemplate");
gvColumn.DataType = typeof(string);
gvColumn.DataMemberBinding = new Binding(...)

In xaml file I define the template like this:

<telerik:RadGridView.Resources>
                <DataTemplate x:Key="TextBoxEditTemplate">
                    <TextBox Text="{Binding RelativeSource={RelativeSource Self}, Path=DataMemberBinding.PropertyPath}"/>
                </DataTemplate>
...

but the 'Text' of this text box is not bound to content of the cell, they are sperated, when user tries to edit, the cell's content is not
in the TextBox, and vice versa.

Thanks.

Henry

Excel doesn't open when data contains HTML tags

Hi guys,

I noticed that when using ExportFormat.ExcelML with columns containg tags, the generated file cannot be opened. I have a column which contains "<" and ">" and this basically breaks the format. I tried intercepting the value in the ElementExporting event but it doesn't look like it's helping me. A sample event log file froom Excel looks like this:

XML PARSE ERROR: Missing end-tag
Error occurs at or below this element stack:
    <ss:Workbook>
     <ss:Worksheet>
      <ss:Table>
       <ss:Row>
        <ss:Cell>
         <ss:Data>
          <ss:CompanyName>

The value for column CompanyName would be something like "<Acme Inc>"

How do I go about this? I

RadDocking with PRISM 4 + MVVM + MefBootstrapper

I'm using the RegionAdapter from the following article.

http://blogs.telerik.com/blogs/posts/09-08-31/using_the_raddocking_control_with_prism.aspx

However, I'm using PRISM 4 + MVVM + MefBootstrapper.
Has anybody successfully used the RegionAdapter with MefBootstrapper?

I'm getting the following error message...

this

.Container.Resolve

Error 1 'System.ComponentModel.Composition.Hosting.CompositionContainer' does not contain a definition for 'Resolve' and the best extension method overload 'Microsoft.Practices.Unity.UnityContainerExtensions.Resolve<T>(Microsoft.Practices.Unity.IUnityContainer, params Microsoft.Practices.Unity.ResolverOverride[])'

Thank you

protected override RegionAdapterMappings ConfigureRegionAdapterMappings()

{

var mappings = base.ConfigureRegionAdapterMappings();

mappings.RegisterMapping(typeof(RadPaneGroup), this.Container.Resolve<RadPaneGroupRegionAdapter>());

return mappings;

}

IsExpandable Is not hiding the Expand Button

I'm having issues with getting the IsExpandable property to be respected. Basically when my "Parent" has no children, I don't want the expand togglebutton to be shown. Below is some sample xaml that I am using. The resulting grid has the details column fully populated with the togglebuttons when there should be at least one without the button. I've stepped through my StyleSelector code and it is returning the proper style. But it doesn't appear to have any affect. What am I doing wrong?

<UserControl ...>

<UserControl.Resources>

<Style x:Key="NoChildrenRowStyle" TargetType="telerik:GridViewRow">

<Setter Property="IsExpandable" Value="False"/>

</Style>

<Style x:Key="HasChildrenRowStyle" TargetType="telerik:GridViewRow">

<Setter Property="IsExpandable" Value="True"/>

</Style>

</UserControl.Resources>

<local:RowStyleSelector x:Key="RowStyleSelector"

NoChildrenStyle="{StaticResource NoChildrenRowStyle}"

HasChildrenStyle="{StaticResource HasChildrenRowStyle}"/>

<telerik:RadGridView ItemsSource="{Binding ParentsCollectionView}"

RowIndicatorVisibility="Collapsed"

AutoGenerateColumns="False"

RowStyleSelector="{StaticResource RowStyleSelector}">

<telerik:RadGridView.Columns>

<telerik:GridViewToggleRowDetailsColumn />

<telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}"/>

<telerik:GridViewDataColumn Header="Age" DatatMemberBinding="{Binding Age}"/>

</telerik:RadGridView.Columns>

<telerik:RadGridView.RowDetailsTemplate>

<DataTemplate>

<ListBox ItemsSource="{Binding Children}">

<ListBox.ItemTemplate>

<DataTemplate>

<Grid>

<TextBlock Text="{Binding Name}"/>

</Grid>

</DataTemplate>

</ListBox.ItemTemplate>

</ListBox>

</DataTemplate>

</telerik:RadGridView.RowDetailsTemplate>

</telerik:RadGridView>

</UserControl>

RoutingService readonly?!

In XAML, I try to bind the RoutingService of my diagram:

<telerik:RadDiagram ....... RoutingService="{Binding Router}" ... />

And I get this error:

'RoutingService' property is read-only and cannot be set from markup. Line 92 Position 45.

Why do I have to assign this router in code-behind? Makes sense to bind it since it can easily be a property of my viewmodel...

UPDATE: Basically, I'm trying to assign the Router to an instance of OrgTreeRouter.

RadControls for WPF Q3 2012

Hi!
I recently installed "RadControls for WPF Q3 2012" and I see only WPF40 and WPF45 in the binaries folder. What about WPF35 that existed in the previous release? Not available? What does this mean for my projects?

2 Grids with same column width

Hi,

i have a view with two RadGridView, in both the Columns are autogenerated.
In the second one the property ShowColumnHeaders is set to false, so you don't see that there are two grids.
In the view you see a GridView, a black line and then the next GridView.

<telerik:RadGridView x:Name="TodoGrid"

Grid.Row="0"

Width="auto"

Height="auto"

AutoGenerateColumns="True"

CanUserDeleteRows="False"

CanUserFreezeColumns="False"

CanUserInsertRows="False"

CanUserResizeColumns="True"

ColumnWidth="*"

IsReadOnly="True"

SelectionUnit="Cell"

ItemsSource="{Binding ToDoRows}"

RowIndicatorVisibility="Collapsed"

ScrollViewer.VerticalScrollBarVisibility="Visible"

ShowGroupPanel="False" />

.

<telerik:RadGridView x:Name="DoneGrid"

Grid.Row="2"

Width="auto"

Height="auto"

AutoGenerateColumns="True"

CanUserDeleteRows="False"

CanUserFreezeColumns="False"

CanUserInsertRows="False"

CanUserResizeColumns="False"

ColumnWidth="*"

SelectionUnit="Cell"

IsReadOnly="True"

ItemsSource="{Binding DoneRows}"

RowIndicatorVisibility="Collapsed"

ScrollViewer.VerticalScrollBarVisibility="Visible"

ShowColumnHeaders="False"

ShowGroupPanel="False" />

The user can resize the columns in the top grid and i want now that the columns on the bottom grid resize in the same way like the top ones. I try to handle this about the ResizingEvent but don't find a working solution.

Can somebody please support me by this issue.

How to bind the GridViewSelectColumn to a property?

Hi,

I'm using MVVM and I want to control on the ViewModel which rows are selected. To accomplish that I'm trying to bind the GridViewSelectColumn to a property, but that doesn't seem to work because it doesn't accept DataMemberBinding. How can I accomplish that?

    
                        <telerik:RadGridView.Columns> 
        
                            <telerik:GridViewSelectColumn DataMemberBinding=""/> <!-- not valid -->

Thanks in advance,

Wagner
