Hello Robert,
Assume you have two forms form1.aspx and form2.aspx. now you want all the controls of form1.aspx can be retrieve in form2.aspx, in this situation you can use form2.aspx.

In 2.0 we have three options and all come with its +/-ve
A) Response.redirect
-ve : round trips, value can not be passed across pages
b) Server.Transfer
-ve : Loose browser history, but good for value pass and no round trip
C) PostBackUrl
New feature in 2.0 and in my views, you should use this only when you need to transfer from page a to b. Because in background it creates all the page events of page a  ...
So use wisely and smartly...

I will also post this in VB forum. I have a general question. I want to create a "webbased, interactive, and collaborative classroom learning tool". I believe ASP would be a good language for this. However, I also have a strong need to become proficient in VB. My application will be a type of question and answer game to be used in the classroom.
Here is my question; If I first build it entirely VB.net as a VB application, how easy is it to then move it to the Web using ASP?
You can tell from my question, I am not an expert in either or I wouldn't be asking. I know some VB but no ASP. I have six months to work on this so I am somewhat confident I can do whatever needs to be done.
Thanks,
Jinx

Hi,
you can always integrate VB.NET and C# assemblies together if they maintain CTS properly.
For new technologies, I can say that you are well aware of AJAX and WebService. What I can say that you try scriptoculous and dojo libraries for rich user interface.

To learn about ajax technology please search google. you will definitely get good links.
The libraries that I had mentioned are javascript libraries with inbuilt AJAX and effect in it. It will make your life easy for good looks of your pages.
The links are
Scriptaculous[^]
Dojo[^]
Dojo will give you better effects than Scriptaculous, but Scriptaculous is easier to use.
Both the libraries are free.

Hai Friends,
I have a Requirement ,in that Dynamically Textboxes and Dropdowns will be generated
then page will become large, when i click on any dropdownlist(autopostback = true)
it is being post backed, its again starting from page begining
agin i am going to that dropdownlist position,again doing some thing
not doing like this,when i click on it, post back should be done and ctrl should be there only,is there any solution for it?
actually iam using SMARTNAVIGATION = TRUE,It is working fine, postback is done, ctrl is there only
but some times ,it is giving problems some times
we can use ajax for it
but other than that is there any solution for it?

smart navigation is not a good solution, it would not work in Mozilla.

why not... create web request thru javascript. But honestly speaking as per my understading we are all buying same fruits but with different color...
AJAX, POSTBACKURL, XMLHTTPRequest all feature do the same job more and less....
what is your view...

I have a GridView that displays rows of pictures along with text that describes the pictures. One of the columns in the GridView is a template column. In that column I have added a HyperLink. When a user clicks on the HyperLink I want it to go to another page but I want to pass this page the value from another column (my primary key column) in the GridView. So far I have defined the PostBackURL in the HyperLink but how can I get the value from my primary key column in order to pass it as a parameter? Thanks.

U can define DataKeyNames="PrimaryKey" in the html of gridview and on code behind u can do this way:
Dim oGridViewRow As GridViewRow
oGridViewRow = CType(CType(e.CommandSource, Control).NamingContainer, GridViewRow)
ID = grdTitlePlantInformationView.DataKeys(oGridViewRow.RowIndex)("PrimaryKey").ToString
For redirect to another page write this on Row Command of Gridview:
Response.Redirect("frmAnotherPage.aspx?ID=" & ID & "&info= " & e.CommandName)
|
|
|
|
|
What event in the code behind to I add this code?
Dim oGridViewRow As GridViewRow
oGridViewRow = CType(CType(e.CommandSource, Control).NamingContainer, GridViewRow)
ID = grdTitlePlantInformationView.DataKeys(oGridViewRow.RowIndex)("PrimaryKey").ToString

just pass it in the query string... in App A do:
<br />
Response.Redirect("www.appB.com/?run=yes);<br />
Then check it in AppB, you could also encrypt the querty string to protect its contents.

you've asked this at least 3 times, with at least two accounts.
The reason the answers do not change is, reality does not change. If the answers you're getting don't answer your question, try rephrasing it, explaining what it is you want to do, which these answers don't help you with. Or, accept the possibility that what you want to do is impossible. A can only find B if A launched B in the first place. As I've told you at least twice.

Has anyone used web parts and Atlas, or ASP.NET Extentions as it is now known, Update Panel?
I found this [^] video showing the exact functionality I need but it was done with a beta version. The video above using a setting in the tagMapping element of the web.config file, however I can't find any reference to how it works with the release version.
The problem is that when placing web parts (nothing to do with SharePoint) on a page inside an update panel and clicking the verb menu (close, minimize) for any web part. The first action works fine however the menu no longer works.
only two letters away from being an asset
