create on class like product

and do the following things
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public class Product
{
private string _productName;

public string ProductName
{
get { return this._productName; }
set { this._productName = value; }
}

public Product()
{

}
}

--------------------
then create other calls

public class ProductRepository
{
public static IList<product> GetProducts(string criteria)
{
string key = "Products_" + criteria[0];

IList<product> list = CacheRepository.GetObjects<product>(key);

if (list == null || list.Count == 0)
{
list = DataAccess.GetProducts(criteria);
CacheRepository.SaveObject(key, list);
}

// return the list based on the criteria

List<product> productList = list as List<product>;

list = productList.FindAll(delegate(Product product)
{
return product.ProductName.ToLower().StartsWith(criteria.ToLower());
});

return list;
}
}

-------------------------------

public class DataAccess
{
public static IList<product> GetProducts(string criteria)
{
List<product> list = new List<product>();

// Fill the list with any data source

while (reader.Read())
{
Product product = new Product();
product.ProductName = reader["name1"] as String;
list.Add(product); //which fill the list
}
}

return list;
}
}

------------------------------

Then

in the Page_Load or any method
you can bind this way

IList<product> list = null;

Listview listview = new Listview();
listview.DataSource = list;
listview.DataBind();

why you can not bind the data directly to the listview rather then putting it into IList is there any specific reason?
let me know so I can help you better.

I've looked at many of Sacha Barber's articles on WPF, and Josh Smith's, too. Those are great, but I am a total beginner at WPF and those articles are a bit overhead, anyone know of any total beginner tutorials on WPF?

Thanks

Hi Pete,

Thanks for the amazon link. The book looks like it could be worth the money and go along with Josh and Sacha's works.

Go to the article search, if you haven't already done so, and check off WPF under technology and Skill level as Beginner, and many good stuff pop up. It may take sometime to digest it all, but I am sure you'll find it helpful along with the book Pete suggested. I've seen the book at Barnes and Noble and it is a very good looking book. The price on Amazon is good, too.

You may use it like this:

textblock.FontFamily = "Comic Sans MS";
textblock.FontSize = "24";

You won't be able to access the system directory of client machine... Don't do that. Just use the static font list.. You can take a look some Rich Text Editor (Javascript or Silverlight). they don't show all fonts that are installed in client machine..

another thing: if you are using non-English keyboard, you may face some problems with Silverlight..

Thanks and Regards,

Obtain Child from a Grid by clicking Button

Hello everybody!

Maybe someone can help me with this (I'm new to WPF so don't expect too much from my side)

I have a Grid filled with several Items which inherit from Textblock:

public class MatrixElement : TextBlock
   {
       public int GridPositionX { get; set; }
       public int GridPositionY { get; set; }
   }

The GridPositionX and GridPositionY mark the Position inside the Grid.

Now I need to obtain the MatrixElement by clicking on it inside the grid:

private void grid_MouseRightButtonUp(object sender, System.Windows.Input.MouseButtonEventArgs e)
        {
            MatrixElement elem = ???;
        }

If this has something to do with VisualTreeHelper please be so kind and explain it a little bit more.

Thank you in advance.

I think your on the right track, the VisualTreeHelper should do the job for you:

private void grid_MouseRightButtonUp(object sender, System.Windows.Input.MouseButtonEventArgs e)        
{            
    MatrixElement elem = GetDependencyObjectFromVisualTree((DependencyObject)sender, typeof(MatrixElement)) as MatrixElement;
}

private static DependencyObject GetDependencyObjectFromVisualTree(DependencyObject startObject, Type type)
{
    // Iterate the visual tree to get the parent of this control
    DependencyObject parent = startObject;
    while (parent != null)
    {
        if (type.IsInstanceOfType(parent))
            break;
        else
            parent = VisualTreeHelper.GetParent(parent);
    }
    return parent;
}

Hope this helps.

If the event is being raised by the Grid (which is what it looks like),there's no way that going up the tree will find the MatrixElement.

However, if what you actually clicked on was the MatrixElement, you should be able to use the e.OriginalSource property to get the element.

Thanks!

if (e.OriginalSource is MatrixElement)
            {
                MatrixElement elemnt = e.OriginalSource as MatrixElement;
            }

this one works!

I was trying to solve this problem. In many ways I tried, but as per your requirement you have to add "TextBlock", then after that you can highlight the particular cell changing the Foreground colour. Laugh | :laugh:

Now let us have a XAML file, where there is a listview where Employee data such as FirstName,LastName & EmployeeNumber is being populated. I assume you are retrieving data from you database when a specify condition is beieng satisfied such as when FirstName matches the condition. In this case you want to heighlight those cells.

In this case your XAML file looks like:

<ListView.View> Big Grin | :-D

<GridView AllowsColumnReorder="true" ColumnHeaderToolTip="Employee Information">

<GridViewColumn Header="First Name" Width="100" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<l:EditBox Height="25" Value="{Binding Path=FirstName}" Loaded="EditBox_Loaded"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>

<GridViewColumn Header="Last Name" Width="100" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<l:EditBox Height="25" Value="{Binding Path=LastName}" Loaded="EditBox_Loaded"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>

<GridViewColumn Header="ID" Width="50" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<l:EditBox Height="25" Value="{Binding Path=EmployeeNumber}" Loaded="EditBox_Loaded"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>

Now in your cs class

private void EditBox_Loaded(object sender, RoutedEventArgs e)
{
EditBox edtBox = sender as EditBox;

if (edtBox.Value.ToString() == "Yajnesh")
{
edtBox.FontSize = edtBox.FontSize + 4;
}
}

I have tried to paint the background, but it is not straight forward as you have to use the concept dependency property.
