BROWSE E-CHAPTERS

There are three essentail points to understand here. 
1) use the ItemDataBound event to build the HTML that is part of the Grid (cslled dg below).
2) Control columns using e.Item.Cells[12].Text
where 12 here is the column number.
3) Use Case and Switch Statements to evaluate what strings you want to build, eg, grahphics (src= etc), hyperlinks and so on.


private void dg_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if((e.Item.ItemType == ListItemType.Item) || 
(e.Item.ItemType == ListItemType.AlternatingItem))
{
string DetailLink = (e.Item.Cells[1].Text); 
string strSeverity = (e.Item.Cells[3].Text);
string IDkey = e.Item.Cells[0].Text.ToString();
string bit1 = "<a href=";
string FFEwsDetailForm = "\"DetailsFFEWebService.aspx?id=";
string FFEasDetailForm = "\"DetailsFFEValidation.aspx?id=";
string FMSwsDetailForm = "\"DetailsFMSWebService.aspx?id=";
string FMSasDetailForm = "\"DetailsFMSValidation.aspx?id=";
string bit1a = "\"";
string bit1b = " Target=\"_self\" ";   
string bit2 = "><IMG src=\"images\\zoom.gif\" border=none></a>";
string str = (e.Item.Cells[1].Text);
switch(str)
{
case "FMSWS":
e.Item.Cells[12].Text= string.Concat(bit1,FMSwsDetailForm,IDkey,bit1a,bit1b,bit2);
break;  // Use Stringbuilder Class to avoid boxing

e.Item.Cells[12].Text= string.Concat(bit1,FMSasDetailForm,IDkey,bit1a,bit1b,bit2);

The 2003 DataGrid has been renamed to GridView in 2005, the primary differences center around the a range of features that 2003 developers would have often needed to add before are now also available in the "style of" auto generated code for the new Gridview

These kinds of options move the toolset firmly into the RAD category but equally firmly allow programmers to code in more in-depth industrial strength fashion e.g. using an enterprise application blocks' returned data source rather than a more explicit schema dependant one.
