You could create a DataView from the table you want to sort:

<br />
DataSet ds = getMyDataSet();<br />
DataView dv = new DataView(ds.Tables["theTableNameToSort"]);<br />
dv.Sort = "myCoulmnName ASC"; // if you want descending it go's: dv.Sort = "myCoulmnName DESC"; <br />

Hope it helps

Hi,
My page has one DropDownList.
Dropdownlist is binded with DataTable(with one Field) having morethan 100 items.
Now how to set the 99th Item as selectedItem of DropdownList in the page loading itself.
I know the ItemName and value, don't know the index of it.
By using loops its ok.
But it is weaste of our processing time.
Is there any other way to do it.

Thanks
Hari

Try assigning the item index directly like

dropdown.selecteditemindex = 98

printf("Navaneeth!!")

if you know the value then simply you can give dropdownlistid.selectedValue = "value" so that item is selected!!

Why not do it on the page itself:

<br />
asp:DropDownList id="ddlMyList" runat="server" SelectedIndex="<%#ddlMyList.Items.IndexOf(ddlMyList.Items.FindByValue(strTheValueToSelect))%>"<br />
asp:DropDownList><br />

Hope it helps

Yes you can do it without going through loop if index of the item is known. it will not change its index
try this after adding the values to dd
Views.Items[2].Selected=true;

or use this code

int index=Views.Items.IndexOf(new ListItem("String of element"));
Views.Items[index].Selected = true;

Hi,

I hope to be in the right forum with this question:

I would like to create a webservice method, that returns the username of the user that executes its assembly. I hope to be clear here. Typically it would be the ASPNET user that is returned, but i want to get the exact user.

Is this possible? And if so ... what do i have to do ?

don't waste your time, or time will waste you

Hi,
Since the calling of the function in web reference is done by the asp.net user, you can't get the exact user. But you can get it in the webform using the code

Request.LogonUserIdentity.Name give the exact user who is accessing the page.

Request.LogonUserIdentity give the system.security.principal.windowsidentity class object.

Hello,

I am getting a strange problem in my projects (ASP.NET/C#), whenever I try to put the classes into a namespace, an error is generated saying that it cannot resolve the symbol i.e.

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="MyPage.aspx.cs" Inherits="MyPage" %>

works fine, but

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="MyPage.aspx.cs" Inherits="MyNamespace.MyPage" %>

doesn't! any ideas why this might be happening?

Does the code behind look something like this?

<br />
using System;<br />
using System.Data;<br />
<br />
namespace MyNamespace<br />
{	<br />
public class MyPage : System.Web.UI.Page<br />
	{<br />
<br />
private void Page_Load(object sender, System.EventArgs e)<br />

Code file contains the Code Behind file name for your aspx page
And in the Inherits property you should give full name of your code behind class
including the namespace that you have for your project i think you are working in VS 2005 and you added a namespace for your application

That i can't say where have you gone wrong
Did you give same namespace for all classes in the application or
can you post your namespace and class name

Yes, it's like (NOTE: I am typing it by hand (as the code is not in my laptop right now), so please ignore any syntax errors )

namespace LSW
{
     class SignUp : System.Web.UI.Page
       {
         ...........
         ...........

and I trying to access it with inherits="LSW.SignUp" which throws unresolved symbol error.

strangely enough, as soon as I remove the namespace (from both the class and the inherits attribute), the code starts to work...

Yes it happenes many times in 2005 you have partial class and class will not put in any namespace by default
see the code

<br />
namespace MyNameSpace<br />
{<br />
    public partial class ForumTest : System.Web.UI.Page<br />
    {<br />
        int a = 0;<br />
        string[] str ={ "January", "February", "March", "April" };<br />
        strin<br />
<br />

and aspx page contains

<%@ Page Language="C#" EnableViewState="true" AutoEventWireup="true" CodeFile="ForumTest.aspx.cs" Inherits="MyNameSpace.ForumTest" %><br />

see all properties are rigth set
Again i alsp don't have answer to this but when i added namspace in my application it is rumming fine although i faced same problem few months before . No sooner did i got the answer i will let yoy know if you have do the same
