我想在Visual Studio中创建一个搜索栏:
我认为这是一个文本框和图像元素。我的尝试:
<Grid DataContext="{Binding ElementName=Searchpanel}">
<DockPanel>
<TextBox Text="{Binding Path=SearchText}"
Width="150"
Name="tbSearch"
DockPanel.Dock="Left" />
<buttons:ImageButton
ButtonImage="{Binding Path=BtnImage, FallbackValue={StaticResource DefaultSearchImage}, TargetNullValue={StaticResource DefaultSearchImage}}"
ButtonCommand="{Binding Path=BtnCommand}"
Height="{Binding ElementName=tbSearch, Path=ActualHeight}"
DockPanel.Dock="Left" />
<DockPanel>
</Grid>
但我的图片不在文本框附近。此外,似乎图像位于Visual Studio中的文本框内。
感谢您的帮助!

我尝试使用xaml以简单的方式解决这个问题,看看这对你有帮助
<Border BorderThickness="1" BorderBrush="Black" Width="160" Height="21">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBox x:Name="tbSearch" Width="140" BorderThickness="0"></TextBox>
<Button Grid.Column="1" BorderThickness="0" Background="Transparent" Command="{Binding SearchCommand}" Height="{Binding ElementName=tbSearch, Path=ActualHeight}">
<Image Height="10" Width="10" Source="search-icon.png"></Image>
</Button>
</Grid>
</Border>

您可以轻松地在代码后端文件中实现相同的功能:)。选择要放置图像的正确位置。
Label imgLabel = new Label();
imgLabel.Image = Image.FromFile(somefile);
imgLabel.AutoSize = false;
imgLabel.Size = imgLabel.Image.Size;
imgLabel.ImageAlign = ContentAlignment.MiddleCenter;
imgLabel.Text = "";
imgLabel.BackColor = Color.Transparent;
imgLabel.Parent = textBox1;
// pick a location where it won't get in the way too much
imgLabel.Location = new Point(X,Y); //X,Y where you want to keep this image. in your case its at right end.

在LastChildFill="False"
中设置DockPanel
。如果将LastChildFill
属性设置为true(默认设置),DockPanel
的最后一个子元素将始终填充剩余空间,而不管您在最后一个子元素上设置的任何其他停靠值。要将子元素停靠在另一个方向上,必须将LastChildFill
属性设置为false,并且还必须在最后一个子元素上指定显式停靠方向。
<Grid DataContext="{Binding ElementName=Searchpanel}">
<DockPanel LastChildFill="False">
<TextBox Text="{Binding Path=SearchText}"
Width="150"
Name="tbSearch"
DockPanel.Dock="Left" />
<buttons:ImageButton
ButtonImage="{Binding Path=BtnImage, FallbackValue={StaticResource DefaultSearchImage}, TargetNullValue={StaticResource DefaultSearchImage}}"
ButtonCommand="{Binding Path=BtnCommand}"
Height="{Binding ElementName=tbSearch, Path=ActualHeight}" Margin="-40,0,0,0"/>
<DockPanel>
</Grid>
如果您不想使用DockPanel,可以通过Grid轻松完成此操作。
<Grid DataContext="{Binding ElementName=Searchpanel}">
<TextBox Text="{Binding Path=SearchText}"
Width="150"
Name="tbSearch"/>
<buttons:ImageButton
ButtonImage="{Binding Path=BtnImage, FallbackValue={StaticResource DefaultSearchImage}, TargetNullValue={StaticResource DefaultSearchImage}}"
ButtonCommand="{Binding Path=BtnCommand}"
Height="{Binding ElementName=tbSearch, Path=ActualHeight}" Margin="100,0,0,0"/>
</Grid>
