Easily manipulate data with the GridView control in ASP.NET 2.0

Last week, I introduced ASP.NET 2.0's GridView data control and covered the basics of using it. This week, I go a step further by going into the details of working with the data contained in the control. This includes viewing, editing, and deleting data.

Reuse a gridview within calendar control


Hello, I have a calendar control that will have events displayed within each cell.

I want to use a pre formatted gridview and simply bind the gridview with a dataset dynamically and display it within the cell of the specified day.

Is there a way to do that or do I have to dynamically build a gridview for every day that there is an event? 

So here is the template gridview and datasource:

        ConnectionString="<%$ ConnectionStrings:NNTrainingdbconnection %>" 
        SelectCommand="SELECT NN_Fire_Events.Start_Time, NN_Fire_Events.End_Time, tblNN_Fire_Cli

Cutting Edge: Custom Data Control Fields


In ASP. NET 2. 0, the GridView and DetailsView controls are designed to work together. They don't merely provide complementary services, they also share a number of helper classes and components.

Stored Procedures & SqlDataAdapter not updating a calendar control


Hi all,

I have a database linked to a calendar. I had a peice of code that retrieved dates from a database and populated the calendar. I wanted to tidy up my code using stored procedures (they seem neater & i assume there's a benefit somewhere). so i came up with this, however it's not working. The calendar displays, but it's not being populated with the database entries. The SqlCommand & SqlParameter I have working elsewhere in my code; as with the SqlDataAdapter (which also worked before i tried to conver to a stored procedure!) but combining these three (SqlCommand, SqlParameter & SqlDataAdapter) seem to be causing me problems.

It's probably something stupid but if someone could take a look and point me in the right direction, I'd be very grateful.
