如何创建列表视图到网格编程 [英] how to create listview to a grid programmatically

问题描述

我有一个网格列和行定义。通过了解项目的X数量，我可以把它添加到我的XAML没有问题。 Unfortuantely我想以编程方式创建列表视图，因为我想根据项目执行我的SP时，我得到的X数量来填充他们。这是我的XAML。标签有从SP结果给定的内容分配过多。可有人告诉我如何编程创建此？

解决方案

我们可以动态地从code后面添加行或列。

中序添加行：

  GridLength的rowHeight =新GridLength（100）; //你自己的价值，我们可以给*，汽车以及
    RowDefinition rowDef =新RowDefinition {身高=的rowHeight};
    mainGrid.RowDefinitions.Add（rowDef）;
 

中序添加colomns：

  GridLength columnWidth时=新GridLength（100）;
    ColumnDefinition colDef =新ColumnDefinition {宽度= columnWidth时};
    mainGrid.ColumnDefinitions.Add（colDef）;
 

中序在特定行添加文字块，列

  TextBlock的文本块=新的TextBlock（）;
    textBlock.Text =一些价值;
    Grid.SetRow（文字块，的rowNum）;
    Grid.SetColumn（文字块，colNum）;
    mainGrid.Children.Add（文字块）;
 

希望这回答你的问题。

I have a grid with columns and rows define. By knowing x amount of items, I can add it to my xaml no problem. Unfortuantely I want to create the listview programatically because I want to populate them based on x amount of item I get when executing my SP. Here is my xaml. The label is there to assign a given content from the SP result too. Can someone show me how create this programatically?

<Grid Name="grdItems" Width="939" Grid.Row="1" HorizontalAlignment="Left" DataContext="{Binding}" Margin="5">
    <Grid.RowDefinitions>
        <RowDefinition Height="25"></RowDefinition>
        <RowDefinition Height="auto"></RowDefinition>
        <RowDefinition Height="5"></RowDefinition>
        <RowDefinition Height="25"></RowDefinition>
        <RowDefinition Height="auto"></RowDefinition>
        <RowDefinition Height="5"></RowDefinition>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="231"></ColumnDefinition>
        <ColumnDefinition Width="5"></ColumnDefinition>
        <ColumnDefinition Width="231"></ColumnDefinition>
        <ColumnDefinition Width="5"></ColumnDefinition>
        <ColumnDefinition Width="231"></ColumnDefinition>
        <ColumnDefinition Width="5"></ColumnDefinition>
        <ColumnDefinition Width="231"></ColumnDefinition>
    </Grid.ColumnDefinitions>

    <Label Name="lblItem" Grid.Row="0" Grid.Column="0" Content="item label" />
    <ListView Name="lstFirstItem" HorizontalAlignment="Left" VerticalAlignment="Top" 
                    Height="auto" Margin="0,0,0,0" ItemsSource="" FontWeight="Regular" 
                    Grid.Column="0" Grid.Row="1">
        <ListView.View>
            <GridView>
                <GridView.ColumnHeaderContainerStyle>
                    <Style>
                        <Setter Property="FrameworkElement.Visibility" Value="Collapsed"/>
                    </Style>
                </GridView.ColumnHeaderContainerStyle>
                <GridViewColumn Width="58" DisplayMemberBinding="{Binding ItemName}"></GridViewColumn>
                <GridViewColumn Width="174.25" DisplayMemberBinding="{Binding ItemDescription}"></GridViewColumn>
            </GridView>
        </ListView.View>
    </ListView>
</Grid>

解决方案

we can add rows or columns dynamically from code behind.

Inorder to add rows:

    GridLength rowheight = new GridLength(100);  //your own value we can give *,Auto as well  
    RowDefinition rowDef = new RowDefinition {Height = rowheight };    
    mainGrid.RowDefinitions.Add(rowDef);

Inorder to add colomns:

    GridLength columnwidth = new GridLength(100);        
    ColumnDefinition colDef = new ColumnDefinition { Width = columnwidth};        
    mainGrid.ColumnDefinitions.Add(colDef );    

Inorder to add textblock at particular row,column

    TextBlock textBlock = new TextBlock();        
    textBlock.Text = "Some Value";       
    Grid.SetRow(textBlock, rowNum);        
    Grid.SetColumn(textBlock, colNum);
    mainGrid.Children.Add(textBlock);
