Forms Data Controls :: Returning The Number Of Rows From A Table?
Feb 10, 2010
I am trying to follow an example from Lesson #25 of [URL] I am not trying to do paging as the above example is doing. I simply want to do a Query and return the the number of rows back in my code behind.
I have a DAL Typed Dataset with the following Query
SELECT COUNT(*) AS Expr1
FROM Reservation
WHERE (DateUsed = @DateUsed) AND (SiteID = @SiteID)
I have a BLL setup for the above as follows:
[Code]....
[Code]....

I've searched for this several times but have never been able to find the answer with my search terms. Say you have a listview and a datapager set to 10 rows, but you only have 4 data items in the database at the time the query is run. Is there a way to force it to show a 10 row table (4 with data and 6 without)?
Everytime I search on this, I just find information on setting the number of rows for the datapager, which will not show empty rows if the data isn't there. Probably an easy solution, but the heck I can find it.

I'm using a table adapter to perform my queries. I'm sure I'm missing something really easy, but I can't figure out how to return the number of rows returned from a query to a dataset used for a GridView.Basically, I want to display a message "No records exist for your selection" by testing for ReturnedRows = 0.
Excerpt of C# code:
handoutDSTableAdapters.handoutTableAdapter handoutsAdapter =
new handoutDSTableAdapters.handoutTableAdapter();
gv_Handout.DataSource = handoutsAdapter.GetDataByDoctor(Int32.Parse(ddl_MD.SelectedValue));
gv_Handout.DataBind();

i use sql server 2005 and Visual Studio 2008.
I am using asp.ne and vb.net for my website.
i have a table with number of rows 50,000.
i want to display the number of rows at my table in a Label when the page is on load.
so can u give me the code or the hint?
my second question is.
my table has around 50,000 items.
and i have a search box, it look like this
str= select * from mytable where item='car'
the item Car is located in my table in row number of 45,000.
i guess when i search from the table where the item is car, then it will search row by rows, then as the number of rows become huge, it will be so late to find the result.
so is there any method how to search from table with good speed of searching?

I'm looking for the correct syntax to get me the last row of a repeater item and use it in a literal below. As you can see I have the item index syntax already. assume that there is a repeater control surrounding the literal already.
I have already bound the data so it will not use obitemdatabound .
<asp:Literal id="Rpt_ItemCount" runat="server"
Text = '<%# (int) DataBinder.Eval(Container, ItemIndex"))%>'></asp:Literal>

I'm pretty new at ASP .NET but not to ASP. I've got a form I need to create where I don't know how many entries will be added. It has the following format:
"Age" "Duration" "Period of Duration" "etc..."
Last30Days
1-5 Months ago
6-11 Months ago
Age
Age
Age
etc.
So the Age column always has the first 3 options and then an unknown number of Age values that can be inserted. I've created a table that has the first four fields (Last30days, 1-5months, 6-11months, age) and I was thinking I could just order by those 4 columns for display. The problem I have is I'm not sure on how to proceed. Does anyone have any good ideas on how to handle this situation? Ideally data entry people could use the same form for both entering and displaying the data.

I've got a nested gridview and I'm looking for a way to determine the number of rows in a child gridview, so far no luck. Has anyone come across a solution for this ? Both of these gridviews are bound using ObjectDataSource.

I am trying to create a gridview with a fixed number of rows (5). If the gridivew contains no items then five blank rows will be shown. For each row that a user enters then a blank row will be removed so that there will be a constant number of rows displayed. How might I go about doing this?

I'm sure it was discussed hundred of times, but maybe this time will elucidate some new points )
The question is: do I need to limit number of selected rows in data source for GridView?
When I use paging in GridView does limiting selected rows make GridView work faster?
Now I use ObjectDataSource with Linq in functions.
[Code]....
Does this make sense or I can just use LinqDataSource without thinking of selected rows?

I have created an out-of-the-box (default everything) ASP.NET Dynamic Data Entities Web Site using VS2010, C# and the .NET Framework 4. Created an ADO.NET Entity Data Model based off a MS SQL 2008 R2 database and registered that EF data model for my dynamic data. Everything works great except for the one change I would like to make. By default, the GridViewPager.ascx file provides the values 5, 10, 15 and 20 in the dropdown for GridView's "Results per page" option. I would like to change that to 10, 20, 30 and 40 - with 40 being the default selected option.
I went to the code behind file and modified it to have the values I am wanting. Those values now show in the dropdown, and work if I select them. Problem: when the page is first rendered only 10 rows will show. How can I change this?

It seems that VS always displays more than 20 rows of ListView in its designer. If a page has quite a few of ListViews, it is a bit hassle to move around. Is there any way to reduce the number of displayed rows?

I am trying to show as part of the Gridview table the amount of records found as a total in one of the Gridviews rows. I have some code which does add a row to the Gridview but it does not seem to be counting the number of rows it just shows 0 all the tim. Does anyone know why this might be? you can see the count "visitCount" and the dt.Rows.Add but it doesn't increment

Using C#, how can I check the total number of rows returned from a database when using a Repeater? The reason I need to check is I need to alter the presentation of the data when there is only 1 row returned.
