I have a DataGrid that has event handlers bound to SortCommand and PageIndexChanged. How can I determine if those event handlers are about to be called, say on page_load? These events will fire just fine after page_load, but I'd like to know at page_load if they are to be fired.
View 1 RepliesI am trying to determine the number of pages in a custom paged control I have Built
there are 46 records and I am trying to get to the exact number of pages when there are 5, 10, 25 items per page etc...
at 5 items per page I should have 10 pages
and at 10 items per pages I should have 5 pages
but my code returns values that cannot use.
this is my code:
[Code]....
those are values I get.
When maxrowperpage is 5
pagecountConverted is = 9
pagecount is = 9
When maxrowperpage is 10
pagecountConverted is = 5
pagecount is = 5
how can I get a correct quotient?
I have a datagrid with columns programatically populated. I need access to the columns to modify the sort expression prior to render, but the column count is 0 at every stage I try to access them. Break points are hit, but each check of the count = 0.Have tried the following, accessing in various stages of the page / control life cycle, but in all instances, the column count is 0.
protected void Page_PreRenderComplete( object sender, EventArgs e )
{
if (dgPriceInfo != null)

Does anyone know a simple way to determine if a user control is contained in an update panel that was triggered for async postback?
At the moment, the only pseudo logic for this I can think of is?
'Loop through the update panel controls on the page and find the one that is involved in the postback (isInPartialRendering)
'Try to find the user control as a child of the update panel
My client wants to pass values through the query string, but they don't want the query string to be displayed in the browser's address bar. The values being passed are for tracking purposes. I know that postback doesn't happen after you click on href link.Is there any way I can get the value out of the query string without displaying it in the browser's address bar? I think this may be impossible, but I may be wrong; I'm hoping to see if anyone has any answers.

I am programatically adding a control to an aspx page and binding a server side event to an index changed event inside the control. (It's a RadListBox from Telerik's ASP.NET controls) The problem is that on the postback triggered from the control, the event doesn't hit its eventhandler because on the postback the control isn't defined. Is there a way to handle this without having to retrace the logic taken before and rebuild the controls so the events that stem from it are processed?

I am using ListView/DataPager.
For performance reasons I page my results at database, using ROW_NUMBER(SQl2005).
At my C# code just comes one page at time. How can I say to DataPager that I have more rows that really are at my List?
I'm using a ListView with a Paged DataSource. When the ObjectDataSource tries to fetch data from the "GetData"-method, the parameter PageSize is set to -1, even though I have set the PageSize to 8 in the DataPager.
Have I forgotten something?

In ASP.NET 4.0 webforms, I'm trying to export a paged ListView control to an Excel file by un-paging the ListView's (trucks) datasource:
dsTrucks.EnablePaging = false;
For a non-paged ListView control, I can get it to work.
Here's the attempt to "un-page" and then export the ListView control:
[Code]....
There's no error but the output in the Excel file is still just one page of the ListView control instead of all rows.
I have a model called 'BusinessPage' which can be associated with 1 or more 'BusinessPageCategories'. So I've got a 3rd table called 'BusinessPagesInCategories' that links these two.I am trying to get a paged recordset of BusinessPages, along with the total number of records (I may have 100 rows in total but only return 20 at a time, but I pass back an int containing that total number in addition to the 20 rows).The problem I have is that, since I implemented the Many-To-Many relationship, it was bringing back the same BusinessPage row x times (where x is the number of categories that BusinessPage is associated with). I only want a single instance of each business page to be returned. So I added the following to my NHibernate Criteria to give Distinct BusinessPage results..SetResultTransformer(CriteriaSpecification.DistinctRootEntity);
Whilst this works for me, in that I'm now correctly getting a single row per BusinessPage (and my Categories property within each BusinessPage contains the correct x categories that it's assigned to), my row count is not reflecting that 'distinct' count - instead, if I have just 1 BusinessPage record which is associated with 3 categories, the row count is 3!?!
public virtual int BusinessPageId { get; private set; }
public virtual IList<BusinessPageCategory> Categories { get; set; }
public virtual string BusinessName { get; set; }

Using a SubSonic (2.2) SqlQuery object, I am querying a view that contains distinct rows from another table. The results of the query, however, contain multiple rows for certain rows in the view. It appears to be because of a join on a temporary table in the query generated to achieve paging. How can I avoid this duplication of rows?
Bonus points: I have to use the view because SubSonic can't do .Paged() and .Distinct() at the same time. Why not?
I got a list of customers I thought I would list in a gridview or a repeater with customer html, it gone have paging. I'm gone have a checkbox for each customer in the list. Do you guys have any suggestions on how I should do to keep the checkbox value when I go to page 2-3-4 ect in the paging. I'm thinking a session to store the id of the checked customers. After I'm done setting the values they go to the database.
Do you got any other ideas then the session I'm thinking of?
I have a gridview that is a directory of people with about 50 pages
How would I make another gridview that had first row with 26 columns, 1 for each letter of the
alphabet and second row with the first page that has last names that start with that letter.
I need to make a large Ebay-style list of listings (think of the page that comes up when you search for something in Ebay, with a photo, title, one-line description, price, that's paged, and sortable). My limited experience with DataGrids in the past always resulted in what felt like a sluggish page to me, but I'm not sure if it would have been faster if I had pieced it together with a data reader instead.So I'm wondering before I even get started, what is the fastest / most efficient way to retrieve and manage this data.Is it more efficient at runtime to use a DataGrid, or to write the paging and sorting in more manually and use a DataReader, or another way?Ebay manages to get thousands of listings to display very quickly, but they've obviously got a lot of manpower to squeeze every last bit of performance they can out of the site, and good high-powered servers.
View 5 RepliesI've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
View 4 RepliesSo I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.

I have been tasked with designing a scheduling system to fit into an existing application. At present I have a SQL Table - Tasks which have a StartDate and EndDate column.
I have a requirement to set the Task as a recurring task i.e. Replace server backup tapes every day, or, Order more stationary once a month.
I am lost on how to design this. I can't seem to find a proper example on the net. can someone point me in the right direction.
I'm currently using asp.net dynamic data. I have used the standard procedure and created as it is shown in the videos a new class to have some tables individually designed. But now I'm running into the problem that the content of the drop down list is not sorted. I don't want to sort it on the SQL server. I already had a look into some forums and I found this:
public static void SortDropDownList(DropDownList ddlList)
{
ArrayList arl = null;
if (ddlList.Items.Count > 0)
{
arl = new ArrayList(ddlList.Items.Count);
foreach (ListItem li in ddlList.Items)
{
arl.Add(li);
}
}
arl.Sort(new ListItemComparer());
ddlList.Items.Clear();
for (int i = 0; i < arl.Count; i++)............
