Forms Data Controls :: Data Flow In GridView Between Different Pages?
Jan 20, 2010
I have a grid view with first name, last name and email address and View details button
if I click on view details button and display all the details
I want to update Email address, first name in that page.
after updating, I want to return to previous page where datagrid is there.
I want updated data in that datagrid.
I did this by creating different page and after clicking on return button, instead of going to previous page, I m redirecting to new page with the datagrid.
If I click on view details button on that page..its throws runtime error.
After searching, I got EnableEventValidation=false, it is working fine, but viewdetails button is not working.

how to put what i am looking for. The best i can describe it is a flowchart type of layout that shows your all your ASP.NET pages and how they are linked to one another.
Example:
----------- -----------
|main page| |error.asp|
----------- /----------
-----------/ ------------
| login.asp| |footer.asp|
------------ /-----------
---------/ ------------
|Home.asp|---|Header.asp|
---------- ------------
/ ------------
--/----------- |Nav bar.asp|
|Products.asp| -------------
--------------
etc etc..
Is there any built-in things like that or 3rd party software that does what i am looking to do above?

I have a gridview with a hyperlink control that allows the user to save pages to it (www.google.ca, asp.net, etc). Unfortunately it always adds the server name to the beginning of their link. [URL] I was wondering is there any way to change that within the control. or should I have it pass a query string to a url handler that will response.redirect them to their actual page?

I am trying to figure out why it won't display the other results when I click on the second and third links created by enabling the paging option the gridview control. it wasn't displaying properly.. also it may not make a lot of sense.. I'm a PHP programmer... I'm learning asp.net as part of a class and we're instructed to use the drag-and-drop method so forgive me, my asp.net skills are lacking and I am having a hard time learning it. Anyway I'm reposting the current code.. hopefully it will display properly this time. Here's the code for default2.aspx..

I am a total novice to VB so bear with me.In my web-based project, I pass an ID field as a parameter in my URL and go through each row in my gridview to find the correct row that matches the ID parameter, like so:
[Code]....
[Code]....
The problem is that this code only works if the corresponding ID is in a row displayed on the first page. I want to loop through each page in the gridview's rows until either the correct ID is found or it reaches the end of the data set. How do I do this? I assume I need another For loop that looks something like...
[Code]....
...that will go right before my other for loop, and one will loop through each page in the gridview. But obviously I've got that For Loop completely wrong. How do I do this correctly?

I reviewed the previous article on a similiar subject, but it was more for C+. I have an Access db feeding a Gridview control, with the defaults of 10 records per page. I know there are more then 10 records for the information I searching on, and pages 2 & 3 are listed in the 'paging' feature in the header. By the way, my page is results.aspx.
Clicking on page 2 results in no additional results being displayed. I understand a little from the other post, that Gridview tied to Access will not automatically show results past page 1, without some additional coding changes.
<asp:GridView runat="server" id="GridView1" AutoGenerateColumns="False" DataSourceID="AccessDataSource1" CellPadding="3" AllowPaging="True" AllowSorting="True" BorderStyle="Solid" BackColor="White" BorderColor="#70C8D0" BorderWidth="1px">
<PagerSettings Position="Top" />
<RowStyle ForeColor="#000066" Height="30px" />........

My webpage has logo..some other controls and a gridview. The gridview can attimes have huge number of records.So when they save the file as a pdf, and the gridview cannot fit on 1 page...some rows of gridview are displayed on 1st page and then continued on next page no headings...So in order to allow all the text on one page and show the grid properly I have enabled paging on gridview. But now the problem is when they save the final page as pdf, they see just the first page of the grid.is there a way that user can save all the pages(gridview) in same file but separate pages or turning off pagination and displaying the grid on next page with heading repeat?

I have a web app where everytime I upload an Excel file, its contents appears in Gridview, which is binded with a DataTable. Using the properties, I have set paging and sorting to true.
When I input a file using fileupload and a submit button, the web app has page numbers at the bottom appear.
It also correctly sorts it, (my page size is set to 10), however, when i click on the next page (pg 2, for instance), nothing shows up until i upload the file and hit submit again.
This is the code in which I build the table:
protected void AddResultToGrid(String url, String result)
{
data = (DataTable)Session["URLSessionData"];
DataRow dr = data.NewRow();
dr[0] = url;
dr[1] = result;
data.Rows.Add(dr);
gdvResults.DataSource = data;
gdvResults.DataBind();
Session["URLSessionData"] = data;
}

Long story short: I'm basically trying to learn visual web developer/asp.net/and how to get all this to work on a shared hosting environment. The idea is to eventually develop this into something a friend of mine with a garage can use to allow his customers to check their various maintenance records. I basically made a small database with a couple of test tables in it and a gridview to display data based on a variable passed from a text box. I finally got it working on my shared hosting server with just one such 'application', but when I tried to add a second one, both stop working. If I put one in default.aspx, and the other in default1.aspx, they both work perfectly. I've tried using the same dataset for both, and different datasets for each, and same behavior. Also tried using 1 and 2 objectdatasources with the same results. Also tried putting each in their own content placeholders and no change. From my research into the subject, I've come to the conclusion that more than one gridview isn't the problem, so I'm extra stumped now. I'm guessing it's something relatively simple for someone who knows this stuff. Oh, I thought it may have something to do with not using default values, so the 'tables' weren't being drawn, so there wasn't 'room' to do so, but after splitting the apps into two different divs, and floating one bottom/right, again, no change.[URL](first working example)[URL](second working example)[URL](both in same page, not working - might not be up yet if someone reads this quickly)

I have a gridview that displays pending cases. I have enabled paging and sorting on any column. By default it loads data sorted by CreatedDate. When I sort it on any page by company name it does the sorting, but when I move to the next page, it looses sorting by CompanyName. How do I hold the sorting across all the pages on the grid?

I am trying to stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.

I've started using ASP.NET MVC on a project and have gotten a few working pages, but I recently ran into a problem where data I was carrying through a hidden field didn't carry for some reason. I can think of a couple of possible reasons and I could try things until something works but I prefer to work on observable empirical data. Thus the point of this inquiry.
I've got a controller (several), a model (several), a view (several), and data in the browser for the JavaScript to chew on. I can unit test my JavaScript code. The browser / view interactions go over the wire, and I can capture that either with Firebug or (if I want to punish myself) Ethereal. I can write unit tests for the controller and for components of the model. The thing that appears to happen in a pure "black box" is the mapping between the model objects and the view form fields. Somewhere in that process, it tries to map data from form fields into model objects before it hands a request to the controller and it tries to map data from the model objects to form fields when it processes the response. Even with the helpers in play, this is a source of bugs. There can be spelling disconnects, or a page might be inadvertently missing one of the fields of a model object because it didn't use it. It would be nice to know if a field didn't map and why.
Since it is happening on the server, this seems like the handoffs should be unit testable or at least loggable. The problem seems pretty bounded. I can't be the first person to have run into this question. Are there any hooks I can use for this? What are the best observation points in the framework to tap the process, both incoming and outgoing?
