在.NET 3.5中,我在窗口中有一個Grid。我用按鈕填充這個網格。當按鈕填充網格並離開視圖時,網格不顯示滾動條。我已將網格垂直滾動設置爲可見,但仍未顯示。WPF Grid不顯示滾動條
<Window x:Name="Window" x:Class="MergeToCheck.CheckList"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
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"
mc:Ignorable="d" Loaded="Window_Loaded" ScrollViewer.VerticalScrollBarVisibility="Disabled"
ResizeMode="NoResize" ShowInTaskbar="False" Topmost="True" WindowStyle="None"
Height="671" Width="846.299" BorderThickness="5">
<Grid>
<Grid x:Name="MyGrid" HorizontalAlignment="Left" Height="535" VerticalAlignment="Top" Width="736" Margin="10,63,0,0" ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Visible">
<Grid.Resources>
<Style TargetType="{x:Type Panel}">
<Setter Property="Margin" Value="0,0,0,6" />
</Style>
</Grid.Resources>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
</Grid>
</Grid>
</Window>
它增加了按鈕的代碼:
CheckList CheckListCtrl = new CheckList();
System.Windows.Controls.Button btn;
int row = 0;
int col = 0;
CheckListCtrl.MyGrid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(100) });
foreach(var c in list)
{
btn = new System.Windows.Controls.Button();
btn.FontSize = 15;
btn.FontWeight = FontWeights.UltraBold;
btn.Content = c.Name;
btn.Style = System.Windows.Application.Current.FindResource(System.Windows.Controls.ToolBar.ButtonStyleKey) as Style;
btn.BorderBrush = new SolidColorBrush(Colors.Black);
btn.BorderThickness = new Thickness(2);
btn.MinWidth = 145;
btn.MaxWidth = 145;
btn.MinHeight = 95;
btn.MaxHeight = 95;
btn.SetValue(Grid.RowProperty, row);
btn.SetValue(Grid.ColumnProperty, col);
CheckListCtrl.MyGrid.Children.Add(btn);
if ((col + 1) % CheckListCtrl.MyGrid.ColumnDefinitions.Count == 0)
{
col = 0;
row++;
CheckListCtrl.MyGrid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(100) });
}
else
col++;
}
如果您的網格有足夠的空間來顯示所有項目,滾動條將不會出現。滾動條僅在物品多於空間時出現。你確定網格中有更多的項目比空間嗎? – Sonhja 2014-11-04 14:12:50
是的,即時100%肯定它已經空間不足,但如果我設置ScrollViewer.HorizontalScrollBarVisibility =「可見」,它應該始終顯示滾動條,無論它是否有足夠的空間。 – CathalMF 2014-11-04 14:15:28
網格不包含任何類型的滾動條。如果你想滾動,你需要'ScrollViewer'像' ... ScrollViewer>' –
