Thanks for posting in this group.
I think maybe you bind the database data into your datagrid every time in
WebForm load event.
Because when you click the button, the page postback to the server,
Page_Load event fires, the datagrid will be rebind again. So the
ItemCommand will not fire(the datagrid was reinitialized). (You can
demonstrate this through add a breakpoint in ItemCommand eventhandler)
So you should bind the datagrid only when the page is not postback.
Code snippet like this:
//I use default sqlserver database to fill the datagrid
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
//Response.Write(Session[0]);
Response.Write(this.GetPostBackEventReference(hoho));
if(!IsPostBack)
{
SqlDataAdapter adapter=new SqlDataAdapter("select * from
jobs","server=localhost;database=pubs;uid=sa;pwd=");
DataSet ds=new DataSet();
adapter.Fill(ds);
DataGrid1.DataSource=ds;
DataGrid1.DataBind();
}
}
this.DataGrid1.ItemCommand += new
System.Web.UI.WebControls.DataGridCommandEventHandler(this.DataGrid1_ItemCom
mand);
private void DataGrid1_ItemCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
if(e.CommandName=="buttonclick")
{
Response.Write(e.Item.Cells[3].Text);
}
}
