How do I access a Controls in a DataList

I am testing code for my project.

I have a DataList in a <form>
In that DataList, I have two Controls.
One Textbox, and one DropDownList
This is in C#.

I want to access the Controls and populate them with data from a hashtable and a SqlDb Connection.
I understand the DataList1.DataSource and DataList1.BindData();  Can I get this to work with both?

Can someone help me see the proper method of choice to do this in C# and to access the DropDownList?

Code is incomplete.

this is because all of your code is in the header template. the header template is used to display headers of columns. you should use itemTemplate and alternative itemTemplate tags in your DataGrid tags. and bind your data in these tags

first thing i wanna tell you is we should use datalist/datagrid controls when we have more than 1 set of records but as in your case u r applying it on header means only one time it will display, so better you directly define textbox/dropdown on table row.
But continue with your ques, on DataBound Event (which calls after each row of dataset fills), i am fetching reference to textbox and dropdown, so then you can dealt with them as normal textbox/dropdown.

      private void DataList1_ItemDataBound(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
                  if (e.Item.ItemType=ListItemType.Header)
                        DropDownList ddl ;
                        TextBox txt1;
                        ddl =(DropDownList)(e.Item.FindControl("ddlName"));
                        txt1 =(TextBox)(e.Item.FindControl("TextBoxName"));
//Now do whatever operation you want these control

Hello rinkujain,

You answer seems closer where I am going.  However, I have another question... How do I access the DataList if the DataList is not the object being the sender?  For example, how do I access if I call the test2.aspx from test.aspx?

1)  Well, what I really want (i believe) is a <form> with controls in it for a user to create a new record.  The new record (form) should auto select the current Month.  I call the page like this page.aspx?cmd=create.  But if I did call it like this I don't have access to "object sender" and the args required to do "e.Item.FinControl".... Is this why you suggest me to use a <form> tag with no DataList?

2) Is there a way to use both Hashtable and a DataSet on the same control?
If you want to pass only few values from page1 to page2 then u can use querystring for that else you can access one form control values from other like

--onclick of button where you want to call other form

then on page2:
Response.Write(Request.Form["TextBox1"] );
