Let us say you have a list box as below. You have a requirement that on click of
button fetch value of the same row button belongs to.
For example if you are clickingthe second cross, you should be able to fetch the value
Pinal, SqlServer , 500 from the list box.
In the above list box
- There is a button (cross image) in each item.
- Text blocks bind with data.
- List box is bind to the collection.
XAML of list box is as below,
<ListBox
x:Name="lstData"
Margin="5,7,6,15">
<ListBox.ItemTemplate>
<DataTemplate
>
<Grid
x:Name="TopGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition
Width="50"
/>
<ColumnDefinition
Width="*"
/>
</Grid.ColumnDefinitions>
<Button
Margin="5,5,5,5"
Click="Button_Click">
<Button.Template
>
<ControlTemplate
>
<Image
Source="delete.png"
VerticalAlignment="Center"
Height="30"
Width="30"/>
</ControlTemplate>
</Button.Template>
</Button>
<Grid
x:Name="nestedGrid"
Grid.Column="1">
<Grid.RowDefinitions>
<RowDefinition
Height="auto"
/>
<RowDefinition
Height="auto"
/>
</Grid.RowDefinitions>
<TextBlock
Text="{Binding
Name}"
Style="{StaticResource
PhoneTextTitle2Style}"
/>
<StackPanel
Grid.Row="1"
Orientation="Horizontal">
<TextBlock
Text="{Binding
Interest}" Style="{StaticResource
PhoneTextSubtleStyle}" />
<TextBlock
Text="{Binding
Totalposts}"
Style="{StaticResource
PhoneTextAccentStyle}"/>
</StackPanel>
</Grid>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
Item source of list box is set to List of Bloggers.
Bloggers is a custom class as below,
public class Bloggers
: INotifyPropertyChanged
{
private string
name;
public string
Name
{
get
{
return name;
}
set
{
NotifyPropertyChanged("Name");
name = value;
}
}
private string
interest;
public string
Interest
{
get
{
return interest;
}
set
{
NotifyPropertyChanged("Interest");
interest = value;
}
}
private int id;
public int
Id
{
get
{
return id;
}
set
{
NotifyPropertyChanged("Id");
id = value;
}
}
private int
totalposts;
public int
Totalposts
{
get
{
return totalposts;
}
set
{
NotifyPropertyChanged("Totalposts");
totalposts = value;
}
}
#region
INotifyPropertyChanged Members
public event PropertyChangedEventHandler PropertyChanged;
// Used to notify the page that a data context
property changed
private
void NotifyPropertyChanged(string
propertyName)
{
if (PropertyChanged !=
null)
{
PropertyChanged(this,
new
PropertyChangedEventArgs(propertyName));
}
}
#endregion
}
Now on the click event of button if you want to fetch a particular list item then
first take the data context as blogger
Now you will able to use the data as below
For the on click event of button you need to write code as below to fetch aparticular
item list value.
private void
Button_Click(object sender,
RoutedEventArgs e)
{
Bloggers data = (sender
as Button).DataContext
as Bloggers;
ListBoxItem
bloggerToDeleteFromListBox = this.lstData.ItemContainerGenerator.ContainerFromIte
(data)
as ListBoxItem;
var Name = data.Name
}
In this way you can fetch the value of a particular list item. I hope this post
