I am working on creating a stored procedure that will output a pivot table. In the pivot table will be either the string NULL or a number. How can I reformat this in ASP.NET so the NULL value becomes a blank cell in the gridview and the number (whatever it is) becomes an 'X' ?

I would like to ask a question on the visual basic codes to loop the gridview to retrieve the values and based on the values, it will be provided as parameters to update to the database table using stored procedure.
Firstly, I have a gridview named grvProduct. The page (ui) will be loaded with data from the database with the use of stored procedures. And only certain values can be edited through the use of template in gridview. So based on those edited values, I'm supposed to pass these values as parameters to the stored procedure which will then update a database table.
Let say, I have 3 records retrieved from the database and displayed in the gridview. And I would like to edit a values in the 3 records, how do I do batch update and pass those parameters to the stored procedure? I went to debug and step through the visual basic codes and realised there were too many arguments specified because I actually loop the gridview.
Below is my visual basic codes:
[Code]....
Below is my Stored Procedure code:

I believe it is the error in the looping of the gridview which results that I could not batch update the data/values.
I have a stored procedure 'RoomIfExists' on my sql server (it does work). It takes a string variable for the Room_No and returns either '1' or '2' depending on the result of the query.
[Code]....
I need to know how to run the sp in c#, passing the variable Room_No and then pull the result from it.I am using a data reader.
This may not be the correct place to put this as it is both a stored procedure AND Visual Studio 2008 problem.
I have the following stored procedure:

I have been mokeying around with it because of what is happening. I have a dataset, call it dataset1. I drag this stored procedure onto the dataset. I EXPECT a datatable to appear, instead the data set adds this store procedure to the queries table adapter and sets the exec mode to 'NonQuery' which unless I am very mistaken, means "don't expect a dataset back from this' when in fact you DO expect a dataset back from this.
The SQL server is a Windows 2000 Server running SQL 2000. It has never caused us a moments grief since we set it up oh-so-many years ago.
If I connect to a different database and drag a query into the same dataset I get a datatable as I expect. I cannot see where / how this procedure could be wrong. The query when executed returns exactly the data I expect, in the format I expect (looks like a table, acts like a table in the Query analyzer).

I have a stored procedure which returns a table. The stored proc is called via a linq datacontext.
It works fine and I get the table back however I really want to also get the title relating to each particular cell returned.
The stored procedure call is like:
var table = DataContext.GetTable().ToList();
So I get a List<GetTable>. The data is fine I just want the column names as well.

I'm populating a gridview from a stored procedure, but I don't want to actually execute the populate till I have all the values filled in the page. (some are static textboxes, a calendar (date) value and some drop-downs that are populated earlier) I see there's nothing like gridview1.show() like there is in c# windows form programming. I tried

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.
View 1 RepliesIm loading some results from a SQL Stored procedure into a Grid View. From my stored procedure I simply get 2 columns returned, Details and Savings, the savings are being returned in the format 30.50123 I want to limit this to 2 decimal places and put a euro sign in front of it like so €30.50, I have managed to do this however its adding a new "savings"column to my Grid view which I obviously don't want. So I now have a savings column with the correct format of €30.50 and my 2 columns from my stored procedure
details and savings. Heres my code....

I'm getting problems to update a database table shown in a gridview using a stored procedure.
My table has 3 columns and my stored procedure is something like:
spUpdateMyTable(@column1 varchar(20), @column2 varchar(50), @id_table integer)
as
update mytable set column1 = @column1, column2 = @column2 where id_table = @id_table
The stored procedure works perfect when I try to execute it in the SQLServer query analizer, but my problem is when I call the sqldatasource update command.
When I do that, it seem that there are problems whith the parameter's names...
I'm doing that whit updateparameters.Add(parameter) and parameter is created whit the same name, tipe and the value that Is shown in the gridView.
I'm looking for in the msdn but everything I founded was about doing that through an update query but I need the stored procedure.
I am trying to show gridview as Stored procedure results sent.

page is displaying with Edit and deleti buttons with no. of rows. But not result set (no data).
I have a gridview in aspx page bound to a stored procedure, and data is loaded from the database. I have 2 problems which I am banging my head against. 1. Stored Proc has default values of NULL ( which is a DateTime db type) and I don't get how to give them as default values and once I have valid date time ( from textbox on form) , I need stored proc to take this value . ( I have done this from server side code but if this is able to acheive from client side that would be great.
2. As shown below my gird view is present ( no columns are bound and since the data is loading from server side ) I am unable to do sorting on the gridview without a sort expression. Does any one know how to do this?? This is my biggest concern. I have checekd all the articles I could find on google

I have a form that has a textbox, a button and a datagridview. The textbox is a parameter of @subschedule. I'm needing to pass the value of the text box to my sql stored procedure and then fill my datagridview with the results of that query.

When i bind gridview to stored procedure what i found it only shows data after enabling Autogeneratecolumns and it also doesnot show any column in boundedfield. Due to which i am unable to apply formating to individual column according to my requirement. One possible reason may be table is created in stored procedure due to which it generate fields at run time.
View 7 RepliesI have a page, let's called that Parameter page, displaying data from a database table using GridView. (The database is a SQL database.) I allow editing of data in GridView. The GridView uses stored procedure to retrieve data and to update data. In my project, users need to log in before using my asp.net project. So at every page, I know who the current user is by using HttpContext.Current.User.Identity.Name. Now as requirement changes, I need to record who has changed what (row) in the Parameter page. The information is to be written to a new table - audit log. Therefore I do not expect to change the Parameter table structure.
I have modified the stored procedure retrieving data. It returns one more column - an empty column with name currentUser. So GridView will create one more column. After data bound, I have the GridView_DataBound() to popluate that column using HttpContext.Current.User.Identity.Name.
I debug it in Visual Studio and am able to see the name of current log in user as the last column in GridView. I change the update stored procedure to take in one more parameter. That parameter, currentUser, takes default value. The default value is an empty string. So if UI part fails to send in the current user name to stored procedure, it just write the empty string as the user name. I change the <asp:SqlDataSource>. I add a <asp:Parameter> for currentUser.
[Code]....
I debug in Visual Studio. However when I save the change, the SQL profiler shows UI sends in @currentUser as NULL. Why?
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.

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...
