How to add text to the GridView in wpf?

[Krishna Aditya]

Hi, I am developing an UI app, in WPF, for the Log window, I have xaml code <ListView x:Name="lstViewLogWindow" ItemsSource="{Binding}" Height="152"> <ListView.View> <GridView> <GridViewColumn Header="Message_Name" Width="Auto" DisplayMemberBinding="{Binding Path= Message_Name}" /> <GridViewColumn Header="DateTime" Width="Auto" DisplayMemberBinding="{Binding Path= DateTime}" /> </GridView> </ListView.View> </ListView> So, I have a grid view with 2 headers Message_Name and DateTime, and I want to assign the data to the 2 columns... I am not able to get the data displayed by using lstViewLogWindow.Items.Add(msg); Actually I want to add some msg into First col and date time into second column, Please help me in doing this. Thanks Ramm

By adding the item explicitly you are overriding the binding mechanism. You should do it by binding. Assign ListView's DataContext with the list of messages.Something like this,

lstViewLogWindow.DataContext = yourListOfMessages;

Ya.. But its not displaying the text in 2 columns/. I added DataContext..                   lstViewLogWindow.DataContext = lstViewLogWindow.Items.Add(DateTime.Now); how to add this to a particular header like DateTime <pre>         <GridView>                                                                                                             <GridViewColumn Header="Message Name" Width="Auto" DisplayMemberBinding="{Binding Path= Message_Name}" />                                     <GridViewColumn Header="DateTime" Width="Auto" DisplayMemberBinding="{Binding Path= DateTime}" />                               </GridView></pre> Pleaes help Thanks Ramm

You have misunderstood what I said. Assign the LIST of MESSAGE to the DataContext. e.g.,

lstViewLogWindow.DataContext = yourListOfMessages;

where yourListOfMessagesis something like 'List<YourMessageType>' and YourMessageTypeis a type having Message_Name and DateTime property

sorry.. really I couldnt get u.. actually as I have 2 columns Message Name and Datetime in my design, yourListOfMessages will be   1. _eventAggregator.GetEvent<StatusBarMsgShowEvent>().Publish("Click on Save to save the Log window Details"); ------------ to be assigned to column1 2 . DateTime.now   ----------- to be assigned to column2... I think I am not getting you wat U said.. but I am expecting this.. in my logwindow --------------------------------------------------------------------------------- Message                                                               DateTime Click on Save to save the Log window Details      09/08/2009 12:15:20AM -------------------------------------------------------------------------------- Thank you, Ramm

This is my best attempt.

public class LogMessage
{
public string Message_Name { get; set; }
public DateTime LogTime { get; set; }
}

Then you have your list of messages like this,

List<LogMessage> messages = new List<LogMessage>();
messages.Add(new LogMessage(){Message_Name = "Dummy Message", LogTime = DateTime.Now});

lstViewLogWindow.DataContext = messages;

HI.. Thanks for the help. But I am doing this using subscribe and publish.. public class LogWindowMsgShowEvent : CompositePresentationEvent<string>       {       }                   _eventAggregator.GetEvent<LogWindowMsgShowEvent>().Subscribe(this.ShowMessage);                _eventAggr.GetEvent<StatusBarMsgShowEvent>().Publish("Database Connection Error"); so, in CompositePresentationEvent&lt;string&gt; I can see a string here.. do I need to add the class Logwindow to the CompostePresentationEvent?? Actually both the CompositePresentationEvent and the presenter it accesses are in diff modules... HOw to handle this/ Please help Thanks Ramm
