GridView -> ItemTemplate EventHandler setzen

Posted By:      Posted Date: October 22, 2010    Points: 0   Category :.NET Framework

Hi all,


i have a dynamically created GridView with a CheckBox by means of TemplateField.ItemTemplate. Now i want to add an EventHandler (CheckedChanged) on it. Is this possible?

          TemplateField tempField = new TemplateField();
          itemplateCheckBox chb = new itemplateCheckBox(dc_.ColumnName, GridView2);
          tempField.ItemTemplate = chb;
          tempField.HeaderText = dc_.ColumnName;


    public void InstantiateIn(Control container)
      CheckBox cb = new CheckBox();
      cb.DataBinding += new EventHandler(this.bindBooleans);
      cb.CheckedChanged += new EventHandler(this.checkBoxChanged);

Trying to put a Form (paypal button) in a GridView ItemTemplate...


So I am trying to put these three paypal buttons in the gridview based on the information with the gridview and the database. For whatever reason, my first button is off-centered in IE and does not work (in firefox, it just doesn't work, but is positioned correctly). All the buttons under the first one work... This is frustrating and I am having issues with it. Any advice on how to fix the problem would be appreciated. I am using Visual Studio 2010 and VB.NET... My code is below.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

WPF, MVVM, Commands from buttons within a Listbox ItemTemplate? (code included)

I want to capture button clicks from within a list item row. Below I have tried to boil the problem down as much as I can. First, here is the xaml <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="test2.MainWindow" x:Name="Window" Title="MainWindow">  <Grid x:Name="LayoutRoot">  <ListView Margin="148,74,0,202" HorizontalAlignment="Left" ItemsSource="{Binding ListData}">   <ListView.View>    <GridView>     <GridViewColumn Header="Item" DisplayMemberBinding="{Binding ItemName}" />     <GridViewColumn Header="Options" Width="200" >      <GridViewColumn.CellTemplate>       <DataTemplate>        <StackPanel Orientation="Horizontal">         <Button Content="Reject" Height="20" Width="80" Margin="5,2" Command="{Binding Commands}" CommandParameter="RejectItem" /> 

Animate listbox items from ItemTemplate

I want to have a slide-in effect for listbox items, when it's first loaded. I'm using ItemTemplate for listbox items and I coule do the slide-in effect from within the template using RenderTransform and DocubleAnimation. but as the Listbox is vertualized, it does the effect everytime new page of data is loaded in listbox. What I want is to animate the visible items in listbox only when DataContext is changed the first time, like messages list in 'Windows Live Mail' thanks in advance.  

XamlParseException thrown when setting ListBox ItemTemplate.

What could be the cause of the issue described below and why is this exception thrown? Having created a DataTemplate like this: <DataTemplate x:Key="{x:Static controls:InternalResourceKeys.ListBoxItemTemplate}" DataType="{x:Type games:GameDefinitionBase}"> </DataTemplate>   I tried to use it as an ItemTemplate in a ListBox:   <ListBox x:Name="list_definitions" HorizontalContentAlignment="Stretch" SelectionMode="Single" ItemTemplate="{StaticResource {x:Static controls:InternalResourceKeys.ListBoxItemTemplate}}"> </ListBox>   where 'InternalResourceKeys' is the following:   static class InternalResourceKeys { static readonly object _listBoxItemTemplate = new object(); public static object ListBoxItemTemplate { get { return _listBoxItemTemplate; } } }   However, the resource lookup throws an exception (pasted at the end). The reason is most possibly this: {x:Static controls:InternalResourceKeys.ListBoxItemTemplate} used as DataTemplate key. What is a bit surprising is that I have already used InternalResourceKeys class as a storage for resource keys in the same application. Thus, the concept of resource keys being retrieved by a static property seems to work. NOTE: when I change all occurences of {x:Static controls:InternalR

WPF: listbox ItemTemplate

We have a list box. Each item is a TextBlock. If the text too long, it will display as Ellipsis "..." at the end inside textblock. if the available list is too long, it will display a vertical scroll bar for the listbox. if the available list can be displayed in one page, the vertical scroll bar will not displayed. We have difine the <ListBox.ItemTemplate> <DataTemplate> <TextBlock Width="610" TextAlignment="Center" TextTrimming="CharacterEllipsis" Padding="3,0" ScrollViewer.HorizontalScrollBarVisibility="Hidden" Foreground="Black" Text="{Binding ProgramName}"/> </DataTemplate> </ListBox.ItemTemplate> The problem with this ItemTemplate, we have to define the textBlock's width in order to align the text content in the center and display the Ellipsis if text content is too long. However the real width is different with/without displaying the vertical scrool bar of listbox. So far we have to base on the vertical scroll bar displayed to decide the textblock's width. Is there someway, we can fix this problem? thx!
