it helps some times Here is the fixed code (click on "Run code snippet" to see how it works)

Binding data to a Button in repeater

should help you out Why not directly set the value to the button's CommandArgument property ?
For example...
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    Int32 value = Convert.ToInt32(e.CommandArgument);
    Response.Redirect("URL?id=" + value.ToString());
}

Data binding in WPF on button click

Hope this helps You should implement INotifyPropertyChanged in your SearchClass and then in setter raise the event:
public event PropertyChangedEventHandler PropertyChanged = delegate { };
public string Output
{
    get { return _output; }
    set 
    { 
        _output = value; 
        PropertyChanged(this, new PropertyChangedEventArgs("Output")); 
    }
}

Why does the data binding not work when i set the data context in my button click handler?


Tag : chash , By : yew tree

seems to work fine My problem turned out to be the same issue as this post. I am using OneWayToSource and when I change the DataContext my property is set to a default value which is currently "" instead of the value of the target as I was expecting. I have found no work around. I will design such that I know what object to create in advance so that the DataContext will be set in the constructor.
