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

There are a couple of things that you might want to check:
+ The version of the ASP.NET that your demo application runs under.
+ Do you really create the application for the demo in IIS? or it's just a sub folder of another web application?
+ Make sure the assembly contains the sales.Global type should appear in the bin folder.
Also, IMHO the Dundas support team may give you better help to get you quickly started with the product.

Hi All,
Little help needed.
I have a datagrid, and I want a functionality for color change of row when "onclick" event occur.
I am able to change the color of the row when "onclick" event occur.
e.item.attribute.add("onclick","this.style.backgroundColor='red'")
But, When I click on another row, I want to deselect the previously selected row.
I tried some code with javascript, but no luck yet.
Any help will be highly appreciated.
Thank you very much,
Robin

no, i am not using property builder. bz i need to pass values of selected datagrid row to client side java script function in order to avoid second server trip.
Thanks

Hi there,
IMO, you can use an hidden box to store the lastest row id selected by user
So whenever an row is clicked, you just set the the row who has the same id as the id stored in the hidden box to the original color...
Hope you get the idea..

Has anyone used custom classes to tie to the GridView, FormView, or DetailsView?
I heard theres a lot of events that have to be implemented. Would you have a link that explains each event that should be implmeneted?
Please no answers telling me to use ADO.NET or anything related to ADO.NET.
I am looking for examples of custom classes not inheriting any classes related to ADO.NET. <-- as you can tell I don't like to use it
If you know the answer or links I would greatly appreciate it.
Thanks,
Nick
And to re-iterate. If you don't know or understand how, please dont answer. I am looking for answers that understands what I am talking about. And if you think your way is better by using ADO.NET please keep it to yourself. Datasets are bulky and will not accomplish what is needed effeciently in a DAL situation. I don't feel like getting into another argument with anyone else.

Why use ADO.Net when you can over complicate things and write your own classes? I love making things harder then they need to be.
how vital enterprise application are for proactive organizations leveraging collective synergy to think outside the box and formulate their key objectives into a win-win game plan with a quality-driven approach that focuses on empowering key players to drive-up their core competencies and increase expectations with an all-around initiative to drive up the bottom-line. But of course, that's all a "high level" overview of things

Actually sorry for being rude. But, telling me to not use classes to represent data make no sense. And I said to please not give me answers related to ADO.NET.
Im interested in a more advanced and true oop representation of data that you are not used to.
And I can make my classes using generics just as fast as you can. Maybe even faster using Generics.
So please read the question next time.

You can use Typed Datasets (as a DAL) then make a classes for business logic that your presentation layer will actually talk to. With the right attributes you can make it so you can set methods as datasources for GridViews and the such. Here are some good overviews:

thats ok DataSets suck

Angry person, aren't you...
Have you had a look at the object data source in .net 2.0? As far as i know, any class that implements IEnumerable can be bound to a .net control like a gridview - it's very simple.
|
|
|
|
|
Actually. I was just annoyed that people who dont know what thier talking about give me answers that are wrong anyways. And it had nothing to do with the question.
But, for the Views(gridview, formview, and detailview) Dino Esposito briefly mentioned in one of his books that you have to extend more than the IEnumerable interfaces. That only works with the data grid.
I just need a list of the interfaces it requires
Thanks,

It works with Gridview. Might i suggest maybe trying it?
