Web Forms :: Unable To Use HasRows With TableAdapter Select Query?
Nov 30, 2010
I have a TableAdapter that consists of an SQL SELECT query.
Need to create an "if" statement that checks to see if the query returned any records.
Tried "HasRows" but Visual Studio 2010 says: Error 2 'Maine_Innkeeper_Site_2010.App_Code.DataAccessLayer.MaineInnsDataset.membersDataTable' does not contain a definition for 'HasRows' and no extension method 'HasRows' accepting a first argument of type 'Maine_Innkeeper_Site_2010.App_Code.DataAccessLayer.MaineInnsDataset.membersDataTable'
could be found (are you missing a using directive or an assembly reference?) E:Ed dataclientsMaine InnkeepersMIA website 2010Maine Innkeeper Site 2010lodging-search-output.aspx.cs 49 83 Maine Innkeeper Site 2010
What's the proper way to check if HasRows is wrong?

I'm creating a webpage with serveral web controls to set search parameters for querying an SQL table. My plan is to use a TableAdapter to hold the query. If the user decides not to use one, several, or any of the web controls to filter their search, I want the SELECT to execute without complaining that it doesn't have parameter values. Should my SQL query look like

I have a webpage that displays the results of a query on a table. The resulting list is sorted by town:
New York
Hyatt Regency Waldorf Astoria
Paris
Hotel du Louvre Hotel Le Meurice
I've been asked to add to this list another sublist of nearby hotels. The intended result is:
New York
Hyatt Regency Waldorf Astoria nearby hotels:
hotel 1 hotel 2
Paris
Hotel du Louvre Hotel Le Meurice nearby hotels:
hotel 3 hotel 4
I've got a TableAdapter set up in VS2010 so that I can query the table for nearby hotels with "@town" as the parameter. So at the end of each list of hotels in a town, I need to display the results of this query.
If the query turns up no records (no nearby hotels), I don't want to display anything. If it turns up 1 or more records, I want to display the list of nearby hotels.
I am trying to set up a conditional "if" statement that checks to see if any records returned but am getting an error when I try to build:
Error 3 'Maine_Innkeeper_Site_2010.App_Code.DataAccessLayer.MaineInnsDatasetTableAdapters.membersTableAdapter.GetNearbyProperties(string)' is a 'method', which is not valid in the given context E:Ed dataclientsMaine InnkeepersMIA website 2010Maine Innkeeper Site 2010lodging-search-output.aspx.cs 49 49 Maine Innkeeper Site 2010 [Code]....

VS 2008 ASP.NET 3.5 app connecting to an MS SQL 2005 backend. The app contains a strongly typed dataset with a number of TableAdapters. I'm trying to add a query to one of the TableAdapters that deletes from table A, then related entries from table B, then related entries in the master table - table C. The query looks like this:
[Code]....
When I try to run that query to test it out, an error dialog box pops up that says "Unable to parse query text" followed by a second error dialog box that says "Must declare scalar variable @ID". Will the TableAdapters not run sequential Delete statements like this or did I do something wrong?
**Side note: A cascading Delete foriegn key relationship would be ideal, and was configured on the development database, but the DBAs messed up when replicating the database on the production server and getting them to fix something like this can be a difficult process.

I have a quite baffling problem. I've created a Table adapter with 3 queries. 1. GetMemberData() - Return ALL rows. 2. SearchMembersLastName(@q) - Return specified columns from rows that have a column starting with a specified letter. 3. GetMemberDataById(@id)
- Return all rows matching a specified ID.
The Problem is that SearchMembersLastName(@q) is returning ALL coloumns instead of just the ones I want. Here's the query that's in the Table Adapter:
[Code]....
The problem is that it is acting like:
[Code]....
Here's the code that's calling it:
[Code]....
I just can't figure out why this is happening, any help will be greatly appreciated.

I am creating a TableAdapter using corresponding wizard, with a GetDataByID() query. The select statement is like this:select * from books where ID = ?Thus books are filtered by ID. But in case a null is passed as a parameter, I want to select all records rather than none. Could you please tell me how I can do it?

Sure could use some guidance and clarification here. This is an ASP.NET 3.5 app built with VS2008.The data is provided through a strongly typed dataset and TableAdapters containing Ad Hoc queries. A requirement on the project was recently modified. Previously, this query was used to select records based on a specified ZoneID:
[Code]....
The requirement now is that if no ZoneID is selected, the page passes a value of 0, it ignores the WHERE statement and selects all records. Otherwise, it passes the integer value to ZoneID and selects all records associated with that ZoneID.
I have tried several variations including CASE statements in the WHERE clause and surrounding the entire query. I also tried [Code]....
By including a SET statement in SQL Server Management Studio, this works. However, Ad Hoc queries in TableAdapters do not support DECLARE statements.
This also did not work: [Code]....
And neither did this: [Code]....

So, I have 3 table adapters in my dataset, and trying to configure the objectDataSource will not give me the option to select the correct table adapter.
I set up a temporary website to illustrate what I am talking about, along with pics, not much, just 4 pics.
https://sites.google.com/site/configuringobjectdatasource/
The first 2 pics are irrelevant but just in case anyone thinking I don't have it set up properly. The other table adapters are working fine, which I have gridviews being populated etc.
why it will not give me the option to select aspnet_GetRecordDatesTableAdapter?

I am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.

I have a gridview that has a sqldatasource for it's data and it works well. I also have four dropdown lists that I need to have filter the data in the grid if they have a value selected. Here's my query:
[Code]....
What I need is if a user selects an Asset_Tag from a dropdown list the gridview should requery with the Asset_Tag as a parameter so only that record gets called up. Is there a way to do this in the selected indexchanged event? The same would hold true for the other DDLs. It seems like if I assigne the datasourse programmatically I lose the builtin sorting ability which isn't acceptible for this application.

I've got an issue with the postback property. I have a chart (Code below) which has two series pulled from a datasource.
Both series display fine but I've enabled the bars in the chart to respond to the click event and when items from the first series is selected, everything works fine. However, I try to pull the x value for the second series, which is supposed to be a date, but all I get is an interger.

I have some code in my vb.net code behind that queries a database, and if there is data, outputs it from the codebehind to a datalist on my asp.net page. In addition to sending the data to the datalist on the page, I need to take the value from "mbillaty" that is returned from the sql query, and have that value be the selected value for a drop down box also on the page. I can get either the datalist to fill, or the selected value for the dropdown box to be selected depending upon which bit of code I place before the other (ARGH), but I can't get them to both work together on the page. What am I doing wrong?
