Dynamically Assign Parameter to SqlDataSource Parameter Collection
SqlDataSource allows you to Select/Insert/Update/Delete the data from the database without even writing a single line of code. But sometimes you need to dynamically assign a parameter. First let's take a look at the simple update which does not dynamically assign the parameters. In the example below I am using a simple GridView control and updating the UserName, FirstName and LastName. The Bind("UserName") will get the username from the database and display it on the screen and it will also send ......

Closing Parent Window Using the PopUp Window
Sometimes we need to open a small popup window and close the main (parent) window. Although you can achieve this by using a simple window.close(); or self.Close() method but when you try to close the parent window the security kicks in and asks that if you are sure that you want to close the parent window. You can however force the parent window to close without being asked. Here is the small code (originally written by JL): function OpenMainPage() { // open a new page window.open('Page2.htm','Pa... ......

IFRAME With ATLAS Causing Problems

I created a webpage which has few ATLAS controls and some of my custom code to display the Context Help. My Context Help appears as it should be but after it appears all the controls on the webpage dies. It means none of the controls responds to any events. The menu at the top which is a asp:Menu control stops working.

All I am doing is loading a static html page in the IFRAME when the mouse is placed on the link.

My page also inherits from a master page.

ListControl.AppendDataBoundItems
There is a new AppendDataBoundItems property available in ASP.NET 2.0 framework which allows you to add items to the ListControls even if the ListControl is bound to the data source.

ATLAS ReOrderList with ObjectDataSource and SqlDataSource Controls
ATLAS ReOrder List allows the user to well reorder the items in the list. Although it does provides the built in drag and drop functionality but lacks the sorting functionality and hence the developer has to implement it manually. I have demonstrated the examples of using the ATLAS ReOrderList control with the SqlDataSource and ObjectDataSource control. Database Table Schema: CREATE TABLE [dbo].[Categories] ( [CategoryID] [int] IDENTITY (1, 1) NOT NULL , [CategoryName] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS ......

GridView Export to Excel Formatting Issue Solution
Those of you who have exported the GridView to Excel might have noticed that if you try to export a GridView with a column which displays number like 0034, 0012, 0045 etc. In other words the first digit is a '0' and the column is a varchar column then the exported excel file contains the data as 34, 12, 45. So, it removes all the zero's from the column data. You can easily keep the zero's by making small modification in the code. You can achieve this by adding style to the column. Check out the complete ......
