I have two drop down in a datagrid.What i want when i select an item from the first the second one should be populated accordingly.My problem is i have created an event handler for the first drop down but how do i call the second drop down to populate
|
|
|
|
|
You can call a function on OnSelectedIndexChanged event of the dropdownlist and in that event you can populate another dropdownlist. Are you getting any problem in this?

how do i cal the second drop down that is the problem .How do i identify the control which is inside a datagrid
|
|
|
|
|
You have to iterate through all the items of the datagrid and then you can find the other dropdown list(findcontrol method) and populate that.

Hi friends,
How to pass the space (" ") in Request.QueryString in ASP.NET.
In my Application i am passing the path of the folder through Querystring. But if the name of the folder consists two words inbetween space it gets only the first word and check for that folder and says Directory Not Found Exception.
Please Help.
Thanks & Regards

the other issue you might run across is illigal characters in that file.
Since its a small item you'd be better off store that is a session or cache

Hi, I have a asp .net application. In the application I attempt to start a thread from globals "Application_start" method. My problem is that the start page never fully loads and the secondary thread fails on a specific line but it gives me no indication as to which one. Thus I get the message "Server Unavailable". Is this a case of deadlock? or do you need to apply threads differently in asp .net.
cheers

Well, I'm not sure of the specific problem, but here are a couple of links to some excellent articles on threading in ASP.NET. Perhaps you've already read them, but if not, they're good reads:
http://msdn.microsoft.com/msdnmag/issues/05/10/WickedCode/
http://msdn.microsoft.com/msdnmag/issues/03/06/Threading/
You might consider turning on tracing just calling the failing code synchronously until you can determine which line is causing the error.

Hi,
I have two frames, Frame1 and Frame2.I have some buttons in Frame1 and on click of those buttons i want a new page to be displayed in the Frame2.
On the button click, i am using Response.Redirect("abc.aspx") but the page gets opened in the Frame1 itself and not on Frame2.Please tell me how to specify the target using Response.Redirect.So that on any button click present in Frame1, the page gets opened in Frame2.
It's very urgent.
Thanks,
Riz

Response.Redirect method cannot help in this case as it redirects the new page in the current frame. You need to use javascript to get reference to the second frame and load the new page with the src attribute, google can quickly find you the sample script.

I have a page lists many files that allow user to download. User can choose files by checkbox that just right beside the files name. When a user click Download button, all the choosed files have been zipped to a single zip file and a download prompt winodw shows up immideatly and the user can choose a folder to save the file. The download times for each file has been updated into the database. All above processes have been implemented.
Because inside the download function, I use the following statement.
Response.Flush()
Response.Close()
Response.End()
So even I call my update function to refresh the page, it wouldn't work. However, I think the requirement is really fair. After user download spcific files, the download times update and rendered at the same time.
My question is after the zip file has been saved locally, how to refresh(post) the page to show the download times.
Thanks,

IMO, you can open a new web page which is reponsible for downloading the file, and you can refresh the main page in the normal way.

the frame is inside your dom
var myframe = document.getElementById('framenamehere');
then using the DOM do your stuff

Hi Everyone,
I just downloaded an Eval version of Dundas Charting tools and it comes with these Demo projects, however when I try to run the demo projects, for every single one I get this basic error:
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'sales.Global'.
Source Error:
Line 1: <%@ Application Codebehind="Global.asax.cs" Inherits="sales.Global" %>
I tried Building it to fix it and then running it but that did not work for any of them. Please help. Thanks
Sincerely,
The Major Rager
