I think you have to do a delimited string and parse it out in the event handler. IE:

<br />
CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id1") + "|" + DataBinder.Eval(Container.DataItem, "id2")%>'<br />

Two Way Sorting with Up/Down Arrow

Hi Developers

I have performed two way sorting on Datagrid and its working very smoothly(When we first click on header of any column, grid wil b sorted in Acsending Order and when we clcik second time on column header, grid will be sorted in descending order).

Now what I need is that there should be two Arrows Up/Down with each header of Datagrid, Now if we click on Down Arrow the Grid should be sort in Descending Order and When we click on Up Arrow datagrid should be sorted in Ascending Order.

Thanks in advance

Lets work it Out.........!

Hi you can use Headertemplate to add ImageButton with default ImageUrl=Uparrow.

then on Item command you do sorting functon also add the Current- sort critria in viewstate

Then OnItemDataBound event find sorting ImageButton in ListItemType.Header and bases on the Current- sort critria in viewstate change the imageUrl property of ImageButton

Thanks for your reply BUT this all I have done, I need to have two Arrow Buttons with each Column Header and when user click on Up Arrow grid should be sorted in Ascending order and vice versa. I hope its clear now...

When you run as aspx page, what it returns to the browser is just html (as it has to be). The only thing that you would really be changing would be the page extension...

Why?

If you want to speed up the site there are other steps you can take. Try reading "Speed Up Your Site" by these guys: http://www.websiteoptimization.com/speed/. This book is really good even though it is a couple years old. It's worth the read.

In .net you can disable viewstates if your are not using them and try to keep your control IDs shorter. The less characters that are sent to the client the faster the site will be.

Although, if your .aspx pages are NOT "doing" anything then static HTML pages would be faster as it won't have to process any code server side.

Try changing the double quotes to single quotes. I haven't looked closely at this but first guess is that is causing the problem.

Static Variable Vs. Application Object stored variable

Can we use static variables to maintain state in ASP.Net Application in place of storing at Application Object? What are merits/demerits

In traditional ASP, we always had the Application object to store application-wide variables in. This of course came at the price of memory allocations. In .NET we can now take advantage of Static Variables, which in most cases can be faster than accessing the Application object.

In .NET, most objects are actually classes, and Global.asax is no exception. To take advantage of this, we first have to give our Global.asax a Classname. We do this by adding the directive naming mine 'MyGlobals':

<%@ Application Classname="MyGlobals" %>

Then, we specify our Static Variable inside the script tags, using the 'Public' and 'Shared' keywords in the Global.asax:

VB:

Public Shared sGreeting as String = "Visit HarrisonLogic.com!"

C#:

Public Static String sGreeting = "Visit HarrisonLogic.com!"

Now that we have the variable 'sGreeting' set up, we can call it directly from our .aspx page using the Class name and the Variable name:

x = MyGlobals.sGreeting

But in case of at some sitiations you may need to acces certain data with respect to the applications like storing number of hit counts for the application.

Major differences
------------------

1) Static variables cannot persist its value after server post backs.
2) But Application object will persist its value after server post backs

In this case you have to wite Inline script for this page. Simply create a string and save it as ASPX.
Note that in page directive Codebehind attribute should not be there and do write all the login in

Events not responding after re-creation of dynamically created webcontrols [modified]

10-Jul-06 22:37

Hi everyone,

I have a situation where I must add ImageButtons dynamically on a page. This I managed to do, but I need them to respond to the Click event and they won't.

Here's a snippet which represents what I'm doing:

public partial class _Default : System.Web.UI.Page
{
    ArrayList imagenes = new ArrayList();

    protected void Page_Load(object sender, EventArgs e)
    {

        if (!Page.IsPostBack)
        {
            ImageButton ib3 = new ImageButton();
            ib3.ID = "ib3";
            ib3.ImageUrl = "Puesta de sol.jpg";
            ib3.Click += new ImageClickEventHandler(ImageButton_Click);
            ib3.Width = new Unit(100, UnitType.Pixel);
            ib3.Height = new Unit(100, UnitType.Pixel);
            form1.Controls.Add(ib3);
            imagenes.Add(ib3);

            Session["Imagenes"] = imagenes;
        }
        else
        {
            imagenes = (ArrayList)Session["Imagenes"];
            foreach (ImageButton ib in imagenes)
                form1.Controls.Add(ib);
        }
    }

    protected void ImageButton_Click(object sender, ImageClickEventArgs e)
    {
        Page.ClientScript.RegisterStartupScript(GetType(), null, "alert('HEY');", true);
    }
}

After clicking on the ImageButton, the page reloads, enters the Else clause, the ImageButton is restored, but it won't enter the Click handler.
Also, I tried setting the handler manually inside the Else clause after the control has been added to the form but it won't enter the handler either.

My guess is this is happening because asp.net is actually assigning the handler, but the call to the handler is simply 'lost' during the restoration of the controls since it appears asp.net expects to fire events for 'static' controls only.

I've checked that when a Click event is fired for a 'static' ImageButton, the execution path goes through the Page_Load first and ends into the handler. That's why i re-create the control in the Else clause in Page_Load.

It's not as important for me to get every delegate for each control restored(which i guess it actually is) and working, as it is getting all of them getting into one handler as expected, since I'll possibly assing all of them the same handler.

Thanks a lot in advance for any help you could provide,

Oxi

Ok, strangely enough, when I set the handler now, after re-creating the controls, its working. I'm sorry, i thought i had tested this yesterday already.

I guess I can go on now.
Nonetheless, I'm still interested in a way of storing and retrieving the delegates just in case i stumble uppon a situation where I actually need to use different event handlers for different controls.

Thanks for your support,

Oxi.

I am using Datagrid and in it Questions are being displayed from Database.So when user print these questions then Datagrid Header is displayed only on first page .I want datagrid header to be displayed on all print pages.How can this be done.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
