I have a question. I have a datagrid and I want to add a button for deleting a row. Is is possible to display a button in datagrid. I'm running this program on windows ce operating system. I try to use it like this;
var f = shelfControlList.ToList();
List<ShelfControl> sortedProductList = new List<ShelfControl>();
sortedProductList.AddRange(f);
dataTable = new DataTable("InBox");
dataTable.Columns.Add("Name");
dataTable.Columns.Add("Publisher");
dataTable.Columns.Add("ButtonCell");
dataGrid1.PreferredRowHeight = 30;
foreach (var sp in sortedProductList)
{
Button deleteButton = new Button();
deleteButton.Text = "Delete";
deleteButton.BackColor = Color.Red;
deleteButton.Width = 30;
this.btnDelete.Click += new System.EventHandler(this.deleteButton_Click_1);
this.Controls.Add(deleteButton);
dataTable.Rows.Add(sp.name, sp.publisher, deleteButton);
}
dataGrid1.DataSource = dataTable;
Thanks in advance.

How do I bind a value from my object property to a variable so that I can pass it as an argument/parameter for my method "setFavoriteProduct(id_product, favnumber) which is triggered by my button "choiceButton". I require the property value "id_product".
When I bind it to Label "id_productLabel" then I can see it in the View just fine but I need to use the string value in my "setFavoriteProduct" function.
listView.ItemTemplate = new DataTemplate(() =>
{
Image productImage = new Image();
productImage.SetBinding(Image.SourceProperty, "imageURL");
//productImage.HeightRequest = 60;
productImage.HeightRequest = 120;
//productImage.WidthRequest = 60;
productImage.WidthRequest = 120;
productImage.Aspect = Aspect.AspectFit;
Label nameLabel = new Label();
nameLabel.SetBinding(Label.TextProperty, "name");
Label id_productLabel = new Label();
id_productLabel.SetBinding(Label.TextProperty, "id_product");
id_productLabel.IsVisible = true;
Button choiceButton = new Button();
choiceButton.Text = "Vali";
choiceButton.Clicked += (sender, args) => setFavoriteProduct(
id_product,
favnumber
);
return new ViewCell
{
View = new StackLayout
{
Padding = new Thickness(0, 5),
Orientation = StackOrientation.Horizontal,
Children = { productImage, id_productLabel , nameLabel, choiceButton }
}
};
the simplest way to do this is to get the BindingContext from the sender (button) and then get the property from that
choiceButton.Clicked += (sender, args) => {
var context = (MyClass)((Button)sender).BindingContext;
var id = context.id_product;
setFavoriteProduct(id,favnumber);
};
alternately, you could use the Button's Command and CommandParameter properties instead of the Clicked event
How can i get radgrid insert items from clientside.
I have used the following code, but its not working.
var mode = rgBoxLimits.get_isItemInserted();
var insertItems;
var dpToDate;
if (mode) {
insertItems= rgBoxLimits.get_insertItem();
dpToDate = insertItems[0].findElement("dtToDate"); //Not working
}
For edit items, i have the following code and its working fine.
var editedItems = rgBoxLimits.get_editItems();
var dpToDate = editedItems[0].findElement("dtToDate");
The problem is that you are running the get_isItemInserted() and get_insertedItem() method on a RadGrid object, while they are methods for a GridTableView object. See the RadGrid Documentation for more info.
Try this:
function getItems(sender, args) {
var myRadGrid = document.getElementById("MainContent_RadGrid1");
var grid = window.$find("MainContent_RadGrid1");
var mode = grid.get_masterTableView().get_isItemInserted();
mode = true;
var insertItems;
var dpToDate;
if (mode) {
insertItems = grid.get_masterTableView().get_insertItem();
dpToDate = insertItems[0].findElement("dtToDate"); //Not working
}
}
My objective is to give bounce effect to dynamically created images within a for loop.
var sb = new Storyboard();
Storyboard.SetTarget(sb, imageTranslateTransform);
sb.RepeatBehavior = RepeatBehavior.Forever;
sb.AutoReverse = true;
var da = new DoubleAnimation();
Storyboard.SetTargetProperty(da, "Y");
da.From = 0;
da.To = 100;
da.Duration = TimeSpan.FromSeconds(1d);
da.EasingFunction = new QuadraticEase {EasingMode = EasingMode.EaseOut};
sb.Children.Add(da);
sb.Begin();
My Code:
ObservableCollection<SampleCheckedData> interestrates = new ObservableCollection<SampleCheckedData>();
XDocument xmlDocu = XDocument.Load(new MemoryStream(System.Text.UTF8Encoding.UTF8.GetBytes(result)));
interestrates = (from rts in xmlDocu.Descendants("Friend")
select new SampleCheckedData
{
Id = (string)rts.Element("userid"),
Name = (string)rts.Element("name"),
Icon = (string)rts.Element("imageurl"),
VisibleStatus = (string)rts.Element("visiblestatus"),
AppStatus = (string)rts.Element("loginstatus"),
imgBubble =bitmapRed,
}).ToList<SampleCheckedData>();
Then Getting Error as can't implicitly convert system.collection.generic.list to system.collection.observablecollection like that.How to bind listbox items using observable collection?
EDIT:
Button b = sender as Button;
var res = interestrates.Where(a => a.Id.Equals(((System.Windows.FrameworkElement)(e.OriginalSource)).Tag)).ToList();
if (res.Count == 1)
interestrates.Remove(res.First());
interestrates = new ObservableCollection<SampleCheckedData>();
lstFriendRequuest.ItemsSource = "";
bindGetFriends();
Here successfully deleting item from list but after calling bindGetFriends() in that binding the items newly then i am not getting new items getting old items.why the service returning old items list?
Use this extension:
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
public static class Extensions
{
public static ObservableCollection<T> ToObservableCollection<T>(this IEnumerable<T> collection)
{
var observableCollection = new ObservableCollection<T>();
foreach (var item in collection) observableCollection.Add(item);
return observableCollection;
}
}
Usage:
interestrates = (from rts in xmlDocu.Descendants("Friend")
select new SampleCheckedData
{
Id = (string)rts.Element("userid"),
Name = (string)rts.Element("name"),
Icon = (string)rts.Element("imageurl"),
VisibleStatus = (string)rts.Element("visiblestatus"),
AppStatus = (string)rts.Element("loginstatus"),
imgBubble =bitmapRed,
}).ToObservableCollection<SampleCheckedData>();
Change your Observable collection to List,
List<SampleCheckedData> interestrates = new List<SampleCheckedData>();
You can also bind List to ListBox, instead of ObservableCollection
And to solve your other problem of deleting selected item from listbox, try the following code:
var selectedIndex = listbox.SelectedIndex;
var listItems = listbox.ItemsSource as List<SampleCheckedData>;
listItems.RemoveAt(selectedIndex);
listbox.ItemsSource = null;
listbox.ItemsSource = listItems;
If still you are facing problems, let me know
The behaviour Im trying to achieve is to press and hold a listbox item and I should be able to delete the item.
I have created the listbox through code. Everylistitem has a stackpanel which holds two textblocks, ie a date and a string.
How can i get press and hold event for a selectedlistitem?? I have not used binding anywhere.
C#:
for (int i = 0; i < iHistCount; i++)
{
TextBlock dateText = new TextBlock();
TextBlock durationText = new TextBlock();
TextBlock spacer = new TextBlock();
TextBlock spacer2 = new TextBlock();
dateText.FontFamily = (FontFamily)App.Current.Resources["CicleFina"];
durationText.FontFamily = (FontFamily)App.Current.Resources["CicleFina"];
dateText.FontSize = 25;
durationText.FontSize = 25;
dateText.TextAlignment = TextAlignment.Right;
durationText.TextAlignment = TextAlignment.Left;
dateText.VerticalAlignment = System.Windows.VerticalAlignment.Center;
durationText.VerticalAlignment = System.Windows.VerticalAlignment.Center;
spacer.Width = 30;
dateText.Width = 130;
spacer2.Width = 50;
durationText.Width = 170;
DateTime dtHist = pCycMan.GetHistoryDate(i);
strDisplay = dtHist.ToString("dd-MMM-yyyy");
dateText.Text = strDisplay;
if( condition)
{
// logic
durationText.Text = strDisplay;
}
StackPanel st = new StackPanel();
st.Height = 50;
st.Orientation = System.Windows.Controls.Orientation.Horizontal;
st.Children.Add(spacer);
st.Children.Add(dateText);
st.Children.Add(spacer2);
st.Children.Add(durationText);
listboxHistory.Items.Add(st);
}
XAML
<ListBox x:Name="listboxHistory" Height="280" Canvas.Left="60" Canvas.Top="232" Width="360" Foreground="Gray">
Assuming you're using the Silverlight toolkit for a context menu, this link is a good example, and has how to create the menu in code-behind.
http://windowsphonegeek.com/articles/WP7-ContextMenu-in-depth--Part1-key-concepts-and-API
For example here:
StackPanel st = new StackPanel();
st.Height = 50;
st.Orientation = System.Windows.Controls.Orientation.Horizontal;
st.Children.Add(spacer);
st.Children.Add(dateText);
st.Children.Add(spacer2);
st.Children.Add(durationText);
listboxHistory.Items.Add(st);
ContextMenu cm = new ContextMenu();
MenuItem delete = new MenuItem()
{
Header = "Delete",
Tag= "Delete" //you could also put the item itself here, would be a good reference
};
delete.Clicked += //your event handler
MenuItem edit = new MenuItem()
{
Header = "Edit",
Tag = "Edit", //you could also put the item itself here, would be a good reference
};
edit.Clicked += //your event handler
//add the items to the context menu.
cm.Items.Add(delete);
cm.Items.Add(edit);
ContextMenuService.SetContextMenu(st, cm);
