I have been up and down looking on the internet and many people seem to have this problem but its generally solved by changing the container to a grid, constraining the height etc. etc. I can t to seem to get this to work. I have an observableCollection thats feeding into a DataTemplate. I can t for th life of me get the scrollbar working. Its there but not enabling. Thanks Scott

一定是虫子,我只有以下几个...
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="ComfortReportEng.Views.EngineerReport.EngineerReport"
Title="Engineer Report" WindowStartupLocation="CenterScreen" Loaded="Window_Loaded" SizeToContent="WidthAndHeight" >
<Window.Resources>
<CollectionViewSource x:Key="cvsReportList"/>
</Window.Resources>
<Grid Margin="0.125,0.412,3.125,0" Height="471">
<ListBox Margin="23,64,3,0" Width="834.14" ItemsSource="{Binding Source={StaticResource cvsReportList}}"
x:Name="lbReportList" SelectionChanged="lbReportList_SelectionChanged" Background="#FFEEEFE4" />
</Grid>
代码为
private void LoadReportList()
{
int number = 0;
List<int> myNumbers = new List<int>();
while (number < 80)
{
myNumbers.Add(number);
number += 1;
}
_cvsReportList = (CollectionViewSource)(this.FindResource("cvsReportList"));
_cvsReportList.Source = myNumbers;
}
这是从另一个工程复制过来的 。 完全混淆了 。 请不要担心。 这不是一个逻辑问题。 请将此视为一个密钥, 没有解决方案 。 再次向 Scott 干杯 。
我不清楚为什么会发生这种事,但这里就是了。
if (System.Environment.MachineName == "SCOTT-PC")
{
this.txtUserName.Text = "Scott Fisher";
this.txtPassword.Password = "palace";
//LoginOK();
}
else
Keyboard.Focus(this.txtUserName);
If I clear the comments on LoginOK procedure I will get no scrollbar. With it commented and I interact with the login screen then everything is fine. Finally here is the code for the LoginOK. if (LoginService.CheckLogin(txtUserName.Text, txtPassword.Password.ToString())) { Helpers.User.ThisUser = this.txtUserName.Text;
EngineerReport.EngineerReport engReport = new EngineerReport.EngineerReport()
{
Owner = Window.GetWindow(this),
WindowStartupLocation =
System.Windows.WindowStartupLocation.
CenterOwner
};
this.Hide();
engReport.ShowDialog();
}
else
{
this.txtPassword.Password = "";
this.txtPassword.Focus();
}
