Re: Progress bar , Help Needed

27-Jan-10 17:08

Hi
"Sys.WebForms.PageRequestManager" class manages partial-page updates of server UpdatePanel controls in the browser. There are two events which handles before an request made and after completing the request in the browser. These are

1. Sys.WebForms.PageRequestManager beginRequest Event : Raised before processing of an asynchronous postback starts and the postback request is sent to the server.

2. Sys.WebForms.PageRequestManager endRequest Event: Raised after an asynchronous postback is finished and control has been returned to the browser.

You can simply use this events to show and hide your progress bar. See code below

<script type="text/javascript" language="javascript">
                        Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
                        Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function BeginRequestHandler(sender, args)
{
    var elem = args.get_postBackElement();
    ActivateAlertDiv('visible', 'AlertDiv', elem.value + ' processing...');
}
function EndRequestHandler(sender, args)
{
   ActivateAlertDiv('hidden', 'AlertDiv', '');
}
function ActivateAlertDiv(visstring, elem, msg)
{
   var adiv = $get(elem);
   adiv.style.visibility = visstring;
   adiv.innerHTML = msg;                               
}
</script>

dropdown

I have populated a dropdown control.
The items inside the dropdown are: "hello", "you", "there"

based on a few retrieved items from the database, I would like the correct item in the dropdown to be selected.
For example:

string strValue = "you";

ddlgvSources.selectedItem.Text = strValue;

The problem here is that the text in strValue over writes the value inside the dropdown, so when I click on the dropdown to see all the items, it shows:

you
you
there

Do you know why?
Thanks

You are trying to replace the text instead of selecting the required one.
You have to find the correct list item using the method FindItemByText or FindItemByValue of DropDownand then Select it.

ListItem item;
ddl.SelectedIndex = -1;
item = ddl.Items.FindByText("hello");
if (item != null) item.Selected = true;

ListItem item=DropDownList1.Items[DropDownList1.SelectedIndex];
DropDownList1.Items.Remove(item);
DropDownList1.Items.Insert(0, item);
