RadGrid Show/Hide Columns

I'm working on a radgridview and I want the user to be able to have an option to show or hide the columns of the grid withing the application. Is there any property that I can set to true that would do this? If not, Would the best way to implement this be a context menu? I have no room for a checkbox in the application or anything like that. Any code or suggestions would help. Here is the code I currently have to build the grid in the xaml. I am working in C# WPF.

<telerik:RadGridView Name="ExceptionsListBox"

IsReadOnly="True"

ReorderColumnsMode="Interactive"

UseLayoutRounding="False"

EnableRowVirtualization="True"

AutoGenerateColumns="False"

RowIndicatorVisibility="Collapsed"

Background="#FF202020"

RowHeight="20"

GroupPanelBackground="#FF202020"

GroupPanelForeground="white"

telerik:StyleManager.Theme="Expression_Dark" Grouped="ExceptionsListBox_Grouped">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Key}"

Header="Type"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding TypeText}"

Header="Error" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Message}"

Header="Error Message" />

</telerik:RadGridView.Columns>

<telerik:RadGridView.Resources>

<Style TargetType="telerik:GridViewHeaderRow">

<Setter Property="MinHeight" Value="15" />

</Style>

<Style TargetType="telerik:GridViewGroupPanel">

<Setter Property="MinHeight" Value="10" />

<Setter Property="Height" Value="10" />

</Style>

</telerik:RadGridView.Resources>

</telerik:RadGridView>

Spell Check in RadRichTextBox

Hi Team Telerik,

My Code to list spell Check Suggestions in the Context Menu upon right clicking on the wrongly added text in the RichTextBox is n't working any more.
Actually what I did is :-

1. Enabled Richtextbox spell check property.
2) Enabled Richtextbox ContextMenu Enabled Property
3) Read * .tdf file as stream and load dictionary directly from the tdf stream

Private Sub LoadDictionary(ByVal tdfFileStream As Stream)

Dim dictionary As New RadDictionary()

dictionary.Load(tdfFileStream)

CType(Me.radRichTextBox.SpellChecker, DocumentSpellChecker).AddDictionary(dictionary, CultureInfo.CurrentCulture)

End Sub

RadRichtextBox property IsContextMenuEnabled is set to True ,but it is not working.

Is there any property to show spell Check Suggestions apart from customizing the Context menu ?
Will it show the spell Check Suggestions in the Context Menu by adding the Reference to Telerik.Windows.Documents.Proofing.Dictionaries.En-US.dll assembly by default ?

Does anyone have any suggestions why this may be?

Thank you for your time,
Lakshmi

Unable to enter data when GridViewDataColumn is in edit mode

Hello,

I have set up an editable column, with separate templates for view and edit defined.

<telerik:GridViewDataColumn Name="TargetPercentOfAccountMarketValue" Header="% Of Total"
Width="75" HeaderCellStyle="{StaticResource columnHeaderStyle}"

                                            

CellStyle="{StaticResource whatIfCell}"

                                            

DisplayIndex="8" EditTriggers="CellClick,TextInput"

                                            

IsReadOnlyBinding="{Binding NodeType, Converter={StaticResource nodeTypeToIsReadOnlyConverter}}"

                                            

ColumnGroupName="WhatIfAllocation">

telerik:GridViewDataColumn.CellTemplate>

DataTemplate>

TextBlock Text="{Binding Node.TargetPercentOfAccountMarketValue, StringFormat={}{0:P1}}"

                                       

Foreground="{Binding Node.TargetPercentOfAccountMarketValue, Converter={StaticResource negativeColorFormatter}, UpdateSourceTrigger=PropertyChanged}">

</

TextBlock>

</

DataTemplate>

</

telerik:GridViewDataColumn.CellTemplate>

telerik:GridViewDataColumn.CellEditTemplate>

DataTemplate>

TextBox BorderBrush="Transparent" BorderThickness="1"
Text=

"{Binding Node.TargetPercentOfAccountMarketValue, Converter={StaticResource StringToPercentageConverter}, StringFormat={}{0:N2}}"

Background="Transparent"

                                     

Foreground="{Binding Node.TargetPercentOfAccountMarketValue, Converter={StaticResource negativeColorFormatter}}"/><

br

>                        

	</

DataTemplate>

</

telerik:GridViewDataColumn.CellEditTemplate>

</

telerik:GridViewDataColumn>

The reason for the two separate templates is that I need the values formatted differently for viewing and editing.
I can enter into edit mode, i.e. I see the blinking cursor, but I cannot enter any values; backspace works strangely enough, so I can delete any existing value but when I try and enter it fails.

I'd like to know what is wrong with a column setup in this manner.

Thank You

Group Header Display Issue when Enum Binded to GridViewDataColumn

Hi,
I am using 2011 Q3 SP1 ver GridView.
In this Grid i have a column called Status. and it is binded with type of Enum values.
And the sorting should be based on this Status column. (The order what we have in Enum Declaration)
So as binded enum type to datacolumn it is working fine even when I group by Status (Sorting wise)
One more thing is I am using CellTemplate to display the image at row level.
My Problem is
When I group By Status column, as I used Enum Value as DataMemberBinding, Enum Type name is coming as Group Header name.
So I have to show this Group Header names should be human readable.

If I am trying to update the groupheadertemplate with humanreadable text, then again i am facing the issue with sorting when grouping done.

Please help me in this regard.
