binding DataTable to asp:Repeater

2008-05-12T02:45:00.000-07:00

html code :

<asp:Repeater id="Repeater1" runat="server">
<HeaderTemplate>
<table width="100%" border="0" cellspacing="0">
<tr><td colspan="2"><b>Personal Database</b></td></tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td style="background-color:inherit;" colspan="2"> <%# DataBinder.Eval(Container, "DataItem.Name") %> </td>
</tr>
<tr>
<td> <%# DataBinder.Eval(Container, "DataItem.Age") %>
</td>
<td> <%# DataBinder.Eval(Container, "DataItem.Designation") %>
</td>
</tr>
<tr>
<td>
<a href="<%# DataBinder.Eval(Container, "DataItem.Email") %>">
<%# DataBinder.Eval(Container, "DataItem.Email") %>
</a>
</td>
</tr>
</ItemTemplate>
<SeparatorTemplate>
<tr>
<td height="2" colspan="2"><hr /></td>
</tr>
</SeparatorTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>

code-behind :

public partial class DetailsPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable("Personal Database");
dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Age", typeof(Int32));
dt.Columns.Add("Designation", typeof(string));
dt.Columns.Add("Email", typeof(string));
dt.Rows.Add(new string[4] { "Jack", 24, ".net Programmer", "jackdsouza0@gmail.com" });
dt.Rows.Add(new string[4] { "Jill", 23, ".net Programmer", "jilldsouza0@gmail.com" });
Repeater1.DataSource = dt;

Reading CD Rom in C# .NEt

2007-09-04T21:14:00.000-07:00

One of my friends had a trouble in Reading data from the CD. Here is a simple solution which i found out.
In this code, we first find out the Logical Drives which are read only. Once we get all read only drives. We can find out the files from CD which is in CD rom. (Not sure whether it will work with CD Writers).But here is the code, u can use ths code for some other thing. And if u have any other solution for this,you are welcome.

private void ReadData(object sender, EventArgs e)
{

string[] drivesPathTab=Directory.GetLogicalDrives();
for (int i = 0; i < drivesPathTab.Length; i++)
{
DirectoryInfo dirInfo = new DirectoryInfo(drivesPathTab[i]);
if ((dirInfo.Attributes & FileAttributes.ReadOnly) != 0)
{
// if code enters in this block, then drive is Read only
// Check for the file on the drive, If it exists, continue.
}
}

Windows Presentation Foundation Samples from MSDN

2007-08-31T05:11:00.000-07:00

Windows Presentation Foundation Samples
The Windows Presentation Foundation (WPF) samples are divided into two categories: Application samples and Technology samples.
Application samples are end-to-end applications that demonstrate multiple platform features. These samples are intended to show real world usage scenarios, and are an effective way to see the breadth of WPF.
Technology samples are targeted to a specific technology area, such as Controls or Animation. These samples demonstrate specific usage scenarios or features, and are generally not end-to-end applications.

Here is the Link :

IValueConverter sample

2007-08-30T22:26:00.000-07:00

This sample will show you how to use IValueConverter in WPF. It is very handy and very impt concept.Dont miss it.

Here we will populate the DataTable and bind it to the DataContext of the ListView

Now go to XAML and use Styles and triggers to implement our logic of Age as shown below:

Now to support Static Resource ValueConv which we have used above in Style, Create a class which implements IValueConerteras shown below

Nice example to know about 3D in WPF

2007-08-30T21:36:00.000-07:00

This is a nice sample to learn basic on 3D. i found this one in msdn. I think anyone interested in 3d designing shud refere to this link :

Blinking Button

2007-08-30T21:15:00.000-07:00

This is a small code where in i have used Styles, Triggers and a bit of animation of WPF.I have created a custom button which blinks(glows) as it gets loaded. Check it out.To understand a concept of Styles, Triggers, i have kept this sample as simple as possible. For that i have used three ellipses so that code doesnt become heavy to understand.Lets see ...
In resources section i have created a style for an ellipse.In this way we can reuse the style for different ellipses.Other way is creating inline style for an element where u can apply style to that particular element. Click on the beow source code to view it.

Let me know ur comments
