I am using listview contain gridview to bind the data.
How I can use CommandParameter present on button from my .cs file. The button is present inside my gridview. Also how to identity each row by id from my .cs file on button click event.
My code:
<ListView Name="listUsers" SelectionMode="Single" Height="200" SelectionChanged="listUsers_SelectionChanged">
<ListBoxItem></ListBoxItem>
<ListView.View>
<GridView AllowsColumnReorder="true">
<GridViewColumn Header="User Id" DisplayMemberBinding="{ Binding Path=UserId }"></GridViewColumn>
<GridViewColumn Header="Name" DisplayMemberBinding="{ Binding Path=UserName }"></GridViewColumn>
<GridViewColumn Header="Email Id" DisplayMemberBinding="{ Binding Path=Email }"></GridViewColumn>
<GridViewColumn Header="Mobile" DisplayMemberBinding="{ Binding Path=Mobile }"></GridViewColumn>
<GridViewColumn Header="Update" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<Button Height="23" Name="button1" CommandParameter="{ Binding Path=UserId }" Click="button1_Click" Width="75">Button</Button>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
You'll need to create a Command (subclass of ICommand) and set your button command attribute to it.
You are using a click event, so i doubt the command parameter will be available when you handle the event.
if you are only interested in this UserId field and not other features of Command (like CanExecute etc), you can just use the Tag property of the button as you can get this via the code behind.
<Button Height="23" Name="button1" Tag="{Binding Path=UserId }" Click="button1_Click" Width="75">Button</Button>
In your button1_click event you can just access
var UserID = ((Button)sender).Tag; //cast the actual button in the grid

I'm working on some XAML/WPF where we create a template of the form that then get compiled into a dll and this dll is then used by a blackbox application to render the form to the user.
Ideally, I should be able to this entirely in XAML, but I am not fully aware of what can and cannot be done in XAML.
I have the following:
<cad:SortableListView.View>
<GridView DataGridRow.Selected="">
<GridViewColumn Header="Message #" cad:SortableListView.SortPropertyName="MessageId" DisplayMemberBinding="{Binding Path=MessageId}"/>
<GridViewColumn Header="Critical" cad:SortableListView.SortPropertyName="Message.IsReceiptRequested" CellTemplate="{StaticResource criticalCellTemplate}"/>
<GridViewColumn Header="Date/Time" cad:SortableListView.SortPropertyName="Message.SendingTime" DisplayMemberBinding="{Binding Path=Message.SendingTime.LocalDateTime, StringFormat={}{0:G}}"/>
<GridViewColumn Header="Subject" cad:SortableListView.SortPropertyName="Message.Subject" DisplayMemberBinding="{Binding Path=Message.Subject}" Width="140"/>
<GridViewColumn Header="From Terminal" cad:SortableListView.SortPropertyName="Message.SendingTerminal" DisplayMemberBinding="{Binding Path=Message.SendingTerminal}"/>
<GridViewColumn Header="Sender" cad:SortableListView.SortPropertyName="Message.SendingEmployeeId" DisplayMemberBinding="{Binding Path=Message.SendingEmployeeId}"/>
<GridViewColumn Header="Priority" cad:SortableListView.SortPropertyName="Message.Priority" DisplayMemberBinding="{Binding Path=Message.Priority}"/>
<GridViewColumn Header="Event" cad:SortableListView.SortPropertyName="Message.LocalEvent.AgencyEventId" DisplayMemberBinding="{Binding Path=Message.LocalEvent.AgencyEventId}"/>
</GridView>
</cad:SortableListView.View>

<TextBlock Grid.Row="3" Grid.Column="0" TextAlignment="Left" Margin="25,0,0,5">
Reply:
</TextBlock>
<TextBox Grid.Row="3" Grid.Column="1" Text="{Binding Path=ReplyText}" HorizontalAlignment="Stretch" Margin="10,0,30,5"/>
<Button Grid.Row="3" Grid.Column="2" Margin="5,0,30,5" DockPanel.Dock="Right"
Command="{Binding Path=Acknowledge.Command}"
cad:CreateCommandBinding.Command="{Binding Path=Acknowledge}" IsDefault="True">
Acknowledge
</Button>
I need it so that when a row is selected from the grid, the cursor has to jump to the text box and when "Enter" is pressed, the button click event is fired. I think I managed to do that by setting it as the default (IsDefault = "true"). Its the only button on the screen so I'm not too worried about something else firing.
Again, the ideal is to be able to do this in pure XAML, but if a file needs to be attached, kindly show me how to reference this code behind file.
Thank you
I want to check all text boxes on the basis of if the check box is checked. But I don't know how to access all check boxes one by one? I bound it with ApprovalStatus which is of boolean type. Can any one help me to have code in C#?
<CheckBox Content="Check All" Height="16" HorizontalAlignment="Left" Margin="9,193,0,0" Name="Tab2CheckAll" VerticalAlignment="Top" Width="77" Click="Tab2CheckAll_Click"/>
<ListView Height="213" HorizontalAlignment="Left" Margin="9,215,0,0" Name="Tab2EmployeeEffortList" VerticalAlignment="Top" Width="771" AllowDrop="True" IsTextSearchEnabled="True">
<ListView.View>
<GridView>
<GridViewColumn Header="Approved" Width="100">
<GridViewColumn.CellTemplate>
<DataTemplate>
<CheckBox CommandParameter="{Binding}" IsChecked="{Binding ApprovalStatus}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
You need not to access individual checkBoxes. CheckBox is already bounded to property set that instead.
Loop over ItemsSource of ListView and set ApprovalStatus to true for all items in the collection. As long as your underlying source class is implementing INotifyPropertyChanged, it will work fine.
I have 2 ObservableCollection lists, which we can call A and B, then I have a GridView that I want to bind to list A and a ComboBox INSIDE that GridView, that I want to bind to list B.
I've set the ItemsSource property of the GridView by code: gridview.ItemsSource=A (and it works!). About the ComboBox its instance it is not available by code, I suppose because its definition it is enclosed between the DataTemplate tags; so I wonder how to bind the combo to list B, either by code or by XAML.
Follows the XAML code:
<ListView Grid.Row="0" Grid.Column="1" HorizontalAlignment="Stretch" Margin="0,0,0,0" Name="lstReplacements" VerticalAlignment="Stretch">
<ListView.View>
<GridView>
<GridViewColumn HeaderContainerStyle="{StaticResource MyHeaderStyle}" Header="Wrong text" DisplayMemberBinding="{Binding Word}"/>
<GridViewColumn HeaderContainerStyle="{StaticResource MyHeaderStyle}" Header="Replacement" Width="60" DisplayMemberBinding="{Binding Replacement}" />
<GridViewColumn HeaderContainerStyle="{StaticResource MyHeaderStyle}" Header="Type" Width="30">
<GridViewColumn.CellTemplate>
<DataTemplate>
<ComboBox ItemsSource="{??????}" DisplayMemberPath="??????" Grid.Row="1" Grid.Column="0" Name="cmbCorrectionType" Width="75" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
Thanks in advance for the support!

I assume this control is in UserControl and you have set DataContext of that UserControl to the class instance where your both collections CollectionA and CollectionB resides.
You can then bind using RelativeSource:
<ComboBox ItemsSource="{Binding DataContext.CollectionB,
RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType=UserControl}}"/>
Also you can set DataContext of ListView to the class instance and all you need to do is change AncestorType to ListView in place of UserControl in above binding.
I've been messing around with checkboxes and listview in my wpf application. Selecting multiple items seems to work properly, but when I click on an item and not on its checkbox it selects the item and deselects all the others previously selected, how can I fix this ?
Here's my code:
<ListView Name="NewPlace_ActionsList" HorizontalAlignment="Left" Height="254" Margin="10,74,0,0" VerticalAlignment="Top" Width="389" >
<ListView.View>
<GridView>
<GridViewColumn>
<GridViewColumn.CellTemplate>
<DataTemplate>
<CheckBox Tag="{Binding Id}" IsChecked="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListViewItem}}, Path=IsSelected}" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Codice" DisplayMemberBinding="{Binding Path=Id}" />
<GridViewColumn Header="Nome" DisplayMemberBinding="{Binding Path=Name}" />
<GridViewColumn Header="Descrizione" DisplayMemberBinding="{Binding Path=Desc}" />
</GridView>
</ListView.View>
</ListView>
What do you want to accomplish? The system behaves exactly to what you coded: the checkbox is selected only in the selected row. Because the Checkbox "follows" the IsSelected of the row (ListViewItem).
