Hu
I have the following code
How can I put this as a hyperlink i.e. <ahref etc<br="" mode="hold">
I dont want a button showing just a bit of text as the hyperlink
thanks

<asp:hyperlink navigateurl="~/.aspx" visible="false" id="hlrefresh" runat="server" text="Refresh" onclick="javascript:location.reload()">Refresh
|
|

|
|
You don't need to create server control just to call a client-side method.
<input onclick="javascript:location.reload();" type="button" title="Reset" />

i think you can do that in plain HTML
Refresh
<a onclick="location.reload();" href="#" title="Refresh">Refresh</a>

Hi all,
I am using asp.net2.0 , C#.
I would like to know which is the best approach(faster ) to fill dopdownlist
1. making stored procedure and filling data to dropdownlist using datareader
2. passing query and filling data to dropdownlist using datareader
As I am facing problem of slowness of filling data . if you find any better approach or faster approach please guide me. database is not much heavy
Method I used to fill dropdownlist is
<br />
public void FillctrlList2(DropDownList ctrl, string procedurename,string fieldtext ,string fieldvalue , string conn, SqlCommand cmd, int i)<br />
{<br />
<br />
try<br />
{<br />
if (con == null)<br />
{<br />
this.openconnection(conn);<br />
this.con.Open();
<br />
}<br />
if (con.State == ConnectionState.Closed)<br />
{<br />
this.openconnection(conn);<br />
con.Open();<br />
}<br />
ctrl.Items.Clear();<br />
ctrl.Items.Add(new ListItem("Select One", "0" ));<br />
cmd.Connection = con;<br />
cmd.CommandText = procedurename;<br />
cmd.CommandType = CommandType.StoredProcedure;<br />
<br />
rdr = cmd.ExecuteReader();<br />
<br />
ctrl.DataSource = rdr;<br />
ctrl.DataTextField = fieldtext;<br />
ctrl.DataValueField = fieldvalue;<br />
ctrl.DataBind();<br />
<br />
rdr.Close(); <br />
}<br />
catch (Exception ex)<br />
{<br />
throw ex;<br />
<br />
}<br />
}<br />
<br />
regards

There is nothing in that code that would make it slow in any way.
You might make it slightly faster if you loop through the data reader youself instead of using data binding, but not enough to make it noticable unless you are putting thousands of items in the dropdown.
If you really have that many items in a dropdown list, the problem is not the performance of the code, but that you have to rethink your user interface.
Despite everything, the person most likely to be fooling you next is yourself.

Databinding uses the IEnumerator interface to iterate through each item. When we loop through the DataReader, I guess the same thing is happening. So how this can boost the performance ? Please correct me.

The data binding adds a bit of overhead because it can use many different kinds of data sources. You can improve on this slightly as you can write code specificly for the data source and for the data that it contains.

catch (Exception ex)
{
throw ex;
}
Please change that portion to:
catch (Exception ex)
{
throw;
}
By doing it your way, you lose the stack trace and it can be harder to debug future problems. And maybe you actually want to do something in that catch other than rethrowing the error? If not, what's the point of catching it in the first place?
I know this doesn't have anything to do with your problem as I don't see anything wrong with your databinding. So unless you're binding a large set of data like Guffa mentioned, this should work fine.

Using ASP.Net site manageer in VS 2005, membership is integrated into the SQLServer db, not the Express one.
I have the main folder set to allow all users, to allow default.aspx to show.
Then I have subfolders set to deny all users.
Then I have those subfolders allow a role.
On the default.aspx screen I show Loginview indicating your login status.
Project is published to server.
On local machine, rules work. User clicks on link, demands login for page access.
On server rules are ignored, goes right to page.
Any ideas where to look for the problem?
ps. In the site admin tool, I created a user, then checked the db on the server. It is there, so I'm not editing a local db.

Let me know how to hide the "__do javascript postback" in the bottom of the browser.
it occurs when the user clicks link button or button control and so on

Try having a attribute like onMouseOver and have a friendly value for window.status=''. This function appears mostly for controls that postback like LinkButton and ImageButtons.

CODE HORROR!
if (Page.IsPostBack)
{
//do stuff
}
Please don't evaluate a bool to a bool, it's not needed.

Why? There is nothing wrong with if(Page.IsPostBack == true ), this documents the intent of the code more explicitly. You could also make the argue that Page is unnecessary.

You are doing an unnecessary comparison that can be easily avoided. I haven't actually looked at the IL, but the compiler might be smart enough to ignore that comparison. That is not the main reason for avoiding that type of code though.
The main reason is because it's quiet easy to do this by mistake:
if(Page.IsPostBack = true )
And then you've got things happening that you never expected and it's easy to miss this simple istype for hours.
I agree that Page could be omitted, but as you mentioned, it makes the code more explicit in intent. It's possible that someone new to ASP.NET development takes over maintenance on this project and doesn't know that the Page object is available to him.
I guess I shouldn't have said code horror, but it's something that should be avoided.

I have a textbox with initial text that I use as a hint for the user.
I want to clear this text once the user click inside the textbox to enter his own text.
But, I was surprised that there is no handler to the click or focus events of the textbox. So, where can I call my code

Not really an ASP.NET question, but
http://msconline.maconstate.edu/Tutorials/JSDHTML/JSDHTML03/jsdhtml03-02.htm[^]
You're wrong, there is indeed a focus event on a textbox. Perhaps the issue is that you're looking at the server side events that are shown to you by intellisense, when you really want javascript client side events ?

I tried javascript, but the autocomplete does not provide handlers rather than those of server side.
So, I dealed with ASP.NET message board

Yeah, like I said, autocomplete only shows server side stuff, you need to look for client side stuff yourself.
