Error    1    'ASP.ratehistory_aspx' does not contain a definition for 'DataList1_ItemCommand' and no extension method 'DataList1_ItemCommand' accepting a first argument of type 'ASP.ratehistory_aspx' could be found (are you missing a using directive or an assembly reference?)    C:\Documents and Settings\Administrator\My Documents\Desktop\rohini\itransi1\ratehistory.aspx    1    1    C:\...\itransi1\

Its coming because you have not added the DataListItemCommand event in the codebehind and define it in the markup page

solution :

<asp:DataList ID="DataList1" runat="server" OnItemCommand="DataList1_ItemCommand">

code behind:

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)

This error is Coming of because in your ASPX page you have defined 'DataList1_ItemCommand' Event and in your code behind file you dont have right the Defination of that File .. .So in this case you can do 2 things
1. Remove that Event from ASPX page
2. Add that Method Defination with proper Argument in your Code Behind file

just remove that  DataList1_ItemCommand attribute from the HTML markup and error will not be there .its coming because you dont have handler method in your cs file Thanks

How can i add it in the codebehind file.  

in design page. in a table, i have datalist and itemcommand like this.

</ItemCommand>   </asp:DataList>

ItemCommand is an event, and there is no such tag <ItemCommand>

if you want to implement this event then first remove the ItemCommand property from the <DataList ... > tag

then go to the design view: Go to the DataList Event and double Click on the ItemCommand
