Web Forms :: Changing Select Parameters -use Different Procedure To Return Results?
Oct 15, 2010
It seems like this would be fairly straight forward. I've got a gridview that loads up using one stored proc, but I've got a searchbox to filter the grid, and when the user enters some criteria I want to use a different proc to return the results. Something tells me I should be doing this with one procedure, but I can't seem to make that work either. When the form loads, my grid is populated. And if I leave my search criteria blank and search anyway, my grid is still populated correctly. But if I enter search creteria, I get diddley squat. What gives? Here is the relevent snippets.
I am realitivly new to c# and I am trying to do something that is probably simple, but I might just be over thinking it.What I want to do is have an image change based on a return of a sql data call. I am using a stored procedure that reads values and uses a case to switch between red, yellow, green for status. For example, I have nine items that the SP goes through and returns one of the colors. What I would need is if it detects a red, change the image to red and so forth. Now, when I execute the SP in C# I can get the data but it always just reads the last value. So if it had a red in there and the next one is a green, it uses the green. I even thought about reading the colors and using an IF statement adding the values to determine which color should be used.
When Select an entity by linq with entity framework 3.5 ...and thenn select it again using stored procedure ..which change the value for a field for that entity ... i got that with old value ...not procedure value...............When i called that procedure before .. the select ... i got the correct value.........but in my case i shall call the procedure after select with linq statment
I want to have a dropdownlist in the footer row of a gridview. The dropdownlist must be populated with an stored procedure that receives a parameter and has a select. Is that posible?? I think yes but I having problems with the parameters.
[Code]....
The exception says incorrect sintax... but I've changed the procedure for something very simple to solve the problem like select 'hello' or select 1, 'hello' and I'm getting the same problem...
When can I use Stored Procedure? Is this useful for looping into multiple SELECT statements to return single value? How? Can anyone post some sample codes? I have text query and notice that my web application is slow and want to find ways to speed it up. Is there any possible ways aside from Stored Procedures?
I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
When I want to get the output values its okay but I also want returning a table as a result data.But Datareader has no rows.is it possible if I want a returning query result and multiple output values togather ?I wrote a test above.I can get output values as sqlparameters. But Datareader attached to a Gridview is empty.can you detect whats wrong here and it doesnt return a query result.So stored procedure is not standart or ı am doing something wrong.this doesnt raise any exception.but not returning any data.
The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
Got a problem with regards to the file upload control on database updates. The problem is in my CMS, when a user tries to update content for a page it will add null to the fields containing the image path. What I need is for the system to check if the uploader has no image and if hasn't it has to do nothing. It can't add empty strings or null values as this will remove the original image path. Although they still need to be able to do image updates if the uploader has a file(this bits not a problem).
Here is a snipet of code to demonstrate what I'm trying to achieve.
A co-worker of mine just came back from a SQL Server Reporting Services class (we are using SQL Server 2005). In that class they were told that if they had a one to many relationship that they would have to flatten the results into one row of the resultset in order to show the 'many' portion of the relationship. For example, my company has two tables:Jobs Notes/Memo'sor each Job we can have 0 or more Notes/Memo's.According to my co-worker the Report Server must have each of the Notes/Memo's in one row of the resultset. That we therefore have to flatten the list of Notes into Note1, Note2, Note3...etc fields.Is this correct? How would I handle a situation where I didn't know how many Notes there were?
i've got a gridview and sql datasource. Its connected to a stored proc that has four optional parameters. In VS when i set up the data source, if i use the test option, and dont supply any values for the sproc, it returns all the values in the table which is what it should do. Now when i try to fill the gridview, it wont return anything at all unless i provide values for all 4 parameters.
It's not even trying to search because i had sql profiler open and nothing shows up until i provide all 4 values. any idea why it's doing this? How do i get it to actually bind even if provide less then all 4 (or none) of the values?
I want to return integer result from storeprocedure.I have used dataset to return values.My store procedure which i have wrotewhich return three result 0,1,2I want to get this result..how to get that result.
I'm building a web app for my company that will run a query every few seconds against SQL Server, and the data that it returns is which database is restoring and how much % complete it is. I have the query already set up and it works fine.
What I want to do is on my Web Form, have a "div" element that will contain the % complete of a database restore, and have it update every few seconds using the JavaScript timer object:
setInterval(function, interval)
I figure I would need to use XMLHttpRequest to send the request to the web server which will run the SQL query. Am I on the right track? How would I even start to do this?
My SQL query is below:
Use master Select der.session_id, der.command, der.status, der.percent_complete, * From sys.dm_exec_requests as der Where percent_complete > 0
I have a stored procedure that returns a dataset with a different number of columns and different column names depending on user input. How can I use this with a GridView? Normally I define the columns beforehand in a static fashion, but, have never done a dynamic dataset like this.
The update option is using a stored procedure. There are no parameters fro the SP but the error message is saying that parameters are expected. If executed as SQL string then it works OK. I need to use a SP as other updates are required. Code: THIS WORKS
USE [TMSWEBALL] GO /****** Object: StoredProcedure [dbo].[usp_TESTSP] Script Date: 10/06/2010 14:03:38 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[usp_TESTSP] As BEGIN SET NOCOUNT ON added to prevent extra result sets from interfering with SELECT statements. SET NOCOUNT ON; */ INSERT INTO dbo.tbl_DEBUG (ManifestId, ManifestTripId, LocationId, Manifestdate, RouteId, VehicleType, ManifestType) VALUES (1,2,3,'01/01/2010',4,5,6) END >
im new to linq and im having lots of trouble creating complex queries.. My problem mainly is that i am using Linq as a BLL.
i created a dbml (with namespace called DAL) file with 2 tables with a one to many relation. Pop and City. There is a forgien key in pop that points to a city. I also created a class called Pop that inhertis DAL.Pop. Now in my ASPX page, i want to call a function in the Pop class that would retrieve some Pop according to its ID, but i need the city name as well.. Ive been going around this in circles for days. I dont know how to write the Linq syntax and i dont understandd how my function's signature should be like.. I want to recieve a table that i can bind to a Gridview and preferable, specify which coloumns to bind.
I have a array list and am using like a database trying to search for ChildID and ParentID based on certain criteria.
My example below has the following keywords to search for:
Yellow, Mustard, Honey, Orange, Flame, Talisman
I also have a category volume value which I grab the first 2 characters to determine another filter.
My code isn't returning all matches with using 'Contains'. Right now it finds the 'Orange, Flame, Talisman'/AV record and returns 50, 28. My keywords also has 'Yellow, Mustard, Honey'/AV which should return 55 and 28 as well.

I want to passed stored procedure parameters from crystal report to pass those parameter dynamically by arraylist because user will pass parameters by using data driven web pages (can be different reports with different parameter). how can i pass through parameter array lists to crystal report setreportparameters fields.
My code;
public void ConfigureReports(ArrayList valuesLists,ArrayList parameterLists) { rptReportViewer.RefreshReport(); DataBaseHelper.myReportConnectionInfo = new ConnectionInfo(); DataBaseHelper.defineConnection = null;
I have a windows aspx form that I have a TextBox, Button and a GridView. The TextBox is stored as a variable @subschedule and passed to a stored procedure. What I'd like to do is to populate the results of that procedure into my GridView.
I have another post on formatting arrays [URL], thinking that would be the way.. and may be it is.. But let me explain it here and see if thats where i need to focus. I have a class that i use to call 3 different procedures, the values from proc#1 are passed to proc#2 and then proc#2 values passed on to proc#3. Now my problem is that i need the results from proc#3 to be placed in a variable i can pass on to another procedure to execute a query.
Proc#1 returns only 1 record. (easy to place into a session or variable)
Proc#2 returns only 1 record. (easy to place into a session or variable)
Proc#3 returns multple records(its only 1 field that is returned, but can have multiple records), so i need to know what is the best solution to place all records returned into a session or variable to use as a parameter in a query?
Since i need to pass those values to a stored procedure, how can i pass what is returned from proc#3 to my query? One of the parameter of the store procedure is our locations, so my query will look like this:
Select * From tblName Where loc LIKE ('1','2','3' )
So i want to set it up so that the values within the LIKE statement are passed in from the page like so
I have a set of controls on my page, Start Date, End Date, User, Status
Start and End Date are expected to always contain a value
User and Status I want to also have an 'All' option, where in it would return all results/not filter.
One method I can think of using for this, is the put the queries in a If scenario, where
if(user == All), use linq query B if(user != All), user linq query A
where linq query A contains the filtering on Users, and linq query B does not.
What I have so far is
[Code]....
What I need
[Code]....
where User == ??,
can the control that populates that contain a wild card option as well? ie *, so that if user == Name, it filters on Name, or if user == *, it returns all?
