WPF-编程问题和解决

1、wpf中点击button按钮后怎么让TextBlock显示button按钮的值？

 <TextBlock x:Name="CurProtext" Grid.Column="1"  FontWeight="Bold"></TextBlock>

 <Button  Grid.Column="1" Grid.Row="0" Content="{Binding Path=ProSelectInfor.AppFormulaList[0].Name}"  Click="ProBut_click"  FontWeight="Bold"></Button>

 

/// <summary>
/// 项目选择按钮
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
public void ProBut_click(object sender, RoutedEventArgs e)
{
string s = (string)((Button)sender).Content;
CurProtext.Text = s;

}

 

2、如何在wpf中画出多行多列的列表，使用什么控件实现？

DataGrid

 

<DataGrid
ItemsSource="{Binding Path=RunRecordList}" AutoGenerateColumns="False" >
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Path=ProId}" Header="序号" MinWidth="120"/>
<DataGridTextColumn Binding="{Binding Path=ProName}" Header="程序名" MinWidth="120"/>
<DataGridTextColumn Binding="{Binding Path=RunTime}" Header="运行时间" MinWidth="200"/>
</DataGrid.Columns>
</DataGrid>

 

3、打印问题

 

增加wpf控件进入流文档

InlineUIContainer和BlockUIContainer

InlineUIContainer 和 BlockUIContainer 提供了可以在Flow Document中插入WPF控件的能力。InlineUIContainer 可以被声明在像Paragraph等支持inline元素的对象中来Host任意的WPF控件，而BlockUIContainer可以被声明在像Section等支持block元素的对象中。他们都可以host任意的WPF控件。

<Section>

    <Paragraph>

        This contains some text and  

        <InlineUIContainer>

            <Button>Button Control</Button>

        </InlineUIContainer>

         interspersed. 

    </Paragraph>

    <Section>

        <BlockUIContainer>

            <Button>Host In Block Control</Button>

        </BlockUIContainer>

    </Section>

</Section>

 

4、如何外部读取一个文件夹内所有的xml文件的文件名，去掉后缀

 

private void ProRead()
{

ObservableCollection < string >ss = new ObservableCollection<string>();

DirectoryInfo dir = new DirectoryInfo("E:\\1");
foreach (FileInfo d in dir.GetFiles())
{
ss.Add(d.Name.Remove(d.Name.LastIndexOf(".")));
}
ss.ToArray();
ProSelectInfor.ProNameList = new ObservableCollection<string>(ss.ToArray()); 

}
