Using TemplateFields in the GridView Control

  
The GridView is composed of a set of fields that indicate what properties from the DataSource are to be included in the rendered output along with how the data will be displayed. The simplest field type is the BoundField, which displays a data value as text. Other field types display the data using alternate HTML elements. The CheckBoxField, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the ImageField renders an image whose image source is based upon a specified data field. Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the HyperLinkField and ButtonField field types.

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:

 <asp:SqlDataSource ID="sqlcalitemtemp" runat="server" 
        ConnectionString="<%$ ConnectionStrings:NNTrainingdbconnection %>" 
        FilterExpression="Event_Date={0}" 
        SelectCommand="SELECT NN_Fire_Events.Start_Time, NN_Fire_Events.End_Time, tblNN_Fire_Cli

Accessing a row's dropdownlist values AFTER the gridview control is in Edit mode

  
Hello, I have a gridview control. When it goes into Edit mode, there are 3 dropdownlists in one cell that are populated by separate stored procedures during the RowDataBound event. The 1st dropdownlist's value is used as a parameter to determine what the 2nd dropdownlist is populated with. The 2nd dropdownlist's value is used as a parameter to determine what the 3rd dropdownlist is populated with. Everything works fine when the row is first put into Edit mode. While I'm in Edit mode and I change the selection in the 1st dropdownlist, how do I access the control so I can feed this new parameter to the 2nd dropdownlist? I have the first 2 dropdownlists set for AutoPostBack so that the Page_Load event is fired when the user changes a value. I know how to get access to these controls via the FindControl method when the row is being databound but how do I find the control during the Page_Load event? Thanks for any help!!!   Penny
