Here are the steps to add a image dynamically to a table cell in asp.net

tc1 = New TableCell
‘tc1.Text = dr1.Item(6)
If (dr1.Item(6) = 2) Then
tc1.Text = “<img src=images/image1.bmp >”
End If
If (dr1.Item(6) = 1) Then
tc1.Text = “<img src=images/image2.bmp >”
End If
If (dr1.Item(6) = 0) Then
tc1.Text = “<img src=images/image3.bmp >”
End If

Here “tc1″ is the table cell i declared and dr1 is some array item.. Just insert it with any condition and play with your code.

Methods are fired during the page load ?
Init() – when the page is instantiated
Load() – when the page is loaded into server memory
PreRender() – the brief moment before the page is displayed to the user as HTML
Unload() – when page finishes loading.

When during the page processing cycle is ViewState available?
After the Init() and before the Page_Load(), or OnLoad() for a control.

Where do you store the information about the user’s locale?
System.Web.UI.Page.Culture

What’s a bubbled event?
When you have a complex control, like DataGrid, writing an event processing routine for each object (cell, button, row, etc.) is quite tedious. The controls can bubble up their eventhandlers, allowing the main DataGrid event handler to take care of its constituents.

Suppose you want a certain ASP.NET function executed on MouseOver for a certain button.  Where do you add an event handler?
Add an OnMouseOver attribute to the button.  Example: btnSubmit.Attributes.Add(”onmouseover”,”someClientCodeHere();”);

What data types do the RangeValidator control support?
Integer, String, and Date.

Explain the differences between Server-side and Client-side code?
Server-side code executes on the server.  Client-side code executes in the client’s browser.

What is the Global.asax used for?
The Global.asax (including the Global.asax.cs file) is used to implement application and session level events.
How many classes can a single .NET DLL contain?
