i wanna do a log lister app in C#. I have a listbox called LogBox
and i wanna color multiple times a row. like: "[04:30:20] - Admin: Hello" but each variable should be different color at row in Listbox.
How should i do this with button action?
I tried LogBox.Items.Add(LogBox.ForeColor = color.red + "["
etc etc etc. but its doesn't work.
I guess you might be looking for something like this.
It can be easily achieved if you have a model class which is bound to your ListBox. Follow the below steps
Step 1 - Create a model class, say suppose "ListBoxItemModel.cs"
public class ListBoxItemModel
{
public string Text { get; set; }
public Brush ForegroundBrush { get; set; }
}
Note:- I am not following any MVVM approach here for demo. If you are familiar then you can implement with this code.
Step 2 - Create a window with ListBox and define a DataTemplate for your Model class as below in your MainWindow.
Assign the DataTemplate to your ListBox ItemTemplate property.
<Window x:Class="SO61263305.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:SO61263305"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Window.Resources>
<DataTemplate x:Key="LocalTemplate" DataType="local:ListBoxItemModel">
<TextBlock Text="{Binding Text}" Foreground="{Binding ForegroundBrush}" />
</DataTemplate>
</Window.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<ListBox x:Name="ItemsListBox" Grid.Row="0" Height="200" Width="200"
ItemTemplate="{StaticResource LocalTemplate}"/>
</Grid>
Step 3 - Create an List of "ListBoxItemModel" and bound to ListBox from code-behind of your window or user control. In my case it is MainWindow.xaml.cs
private void LoadDataObjects()
{
var items = new List<ListBoxItemModel>();
var item = new ListBoxItemModel()
{
Text = "John ABCD 1",
ForegroundBrush = new SolidColorBrush(Color.FromRgb(0, 0, 0))
};
items.Add(item);
item = new ListBoxItemModel()
{
Text = "John ABCD 2",
ForegroundBrush = new SolidColorBrush(Color.FromRgb(200, 79, 24))
};
items.Add(item);
ItemsListBox.ItemsSource = items;
}
In the above method you need to add each item with the Text which you wanted to display and Foreground Brush.
Step 4 - Call above method from your constructor of code-behind or else you can call from any other events like Button click to load the data to a listbox.
See below of my complete MainWindow.xaml.cs (code behind of the MainWindow)
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
LoadDataObjects();
}
private void LoadDataObjects()
{
var items = new List<ListBoxItemModel>();
var item = new ListBoxItemModel()
{
Text = "John ABCD 1",
ForegroundBrush = new SolidColorBrush(Color.FromRgb(0, 0, 0))
};
items.Add(item);
item = new ListBoxItemModel()
{
Text = "John ABCD 2",
ForegroundBrush = new SolidColorBrush(Color.FromRgb(200, 79, 24))
};
items.Add(item);
ItemsListBox.ItemsSource = items;
}
}
