i'm using jQuery to populate an cascading dropdownlist. But i want to set a selected item after jQuery filled the DDL with items.
View 20 RepliesI want to show a confirm dialog when the user selects an item in a DropDownList. If the user presses "Cancel", I want to stop the postback. Here is the function I add to the onchange event:
function imitateConfirmUnload(event) {
if (window.onbeforeunload = null)
return true;
return confirm("Are you sure you want to navigate away from this page?
You have unsaved changes
Press OK to continue or Cancel to stay on the current page.");
}
And this is the relevant bit of code in my startup script to add the handler to the event:
[code]...
The problem is that the postback occurs even if the user selects "Cancel". If I move the handler on to the click event, it works. But it feels clunky to me.
Edit
Correction: it doesn't work onclick, because the dialog prevents selection, so when the user selects OK, no change has taken place, and no postback when you want it!
Edit 2
The DropDownList is inside an UpdatePanel so that may affect behavior.

else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );

else { document.forms[0].ddlMember.disabled = 0; }

View 1 RepliesI have two pages manager and user both have drop downs as
Week, Months and Years.
User have to enter some data week wise for each months and Manager have to approve that.
To Approve manager select months and week from dropdown on his own page and then navigate to User page.
How does I should bind the drop down so that if manager select 1st week from it's page and goes to view link of user then in drop down of user selected value shold be the same as selected by Manager on his own page.
I am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?
View 2 RepliesI am trying to make a simple dropdownlist.Based off what is selected as the dropdownlist, I want it to open a new webpage.
For example:
Here is the dropdownlist - If they select team1, I want it to open up webpage /team1.aspx If it's team2, team2.aspx and so on.
<form id="form1" runat="server">
I thought this would be pretty simple, and in fact it's working on another dropdownlist on the same View, so I'm hoping I missed something very small that is easy to fix. Here's my code:
[Code]....
When I step through the code, the 'Active' option's 'Selected' property is being set to true. That's expected. But when the View renders, it's not selected and a look at the page source shows that the selected property isn't set. What is the problem here, and what's the solution?

I have a code to display a message when a tab is selected, but now I want to add a background image to the selected tab when it is being selected. Here is the code:
[Code]....
I think something like $(selected tab).css("background-image","url stuff.."); should work but I do not know the syntax for the currently selected tab. Any Idea ? Well, Someone suggested to use $(this).css("background-image","url stuff..");, but this did not apply the image to the current tab but instead the main tab container.
how i handle this problem..Its in hidden filed.
