I am getting the following error:
Must declare the scalar variable "@Approved"
I want to add a parameter to my SqlDataSource1 when certain controls are checked.

How to get sqldatasource1.selectCommand value
[Code]....
i want to set that if nothing return i will display a msg to users.
I have a query that looks like this attached to a sqldatasource :
SELECT [fldBaseline] FROM [BI_PATHS_Target_Baseline] WHERE fldBranch = @fldBranch and
fldyear=@fldyear and fldcategory = @cat
and i want to make a LABEL to read that fldbaseline value and i tried this :
[Code]....
btw the @fldbranch is pulling from a dropdownlist and so it the @year but the @cat is just defined always as 'LEAN' But im not sure what to put inside the select() part. i know you have to put atasourceselectarguments.empty if no parameters, but what would I do here since their are 3?
i have a dropdownlist that bind with sqldatasource1. everytime i load this page, dropdownlist will display directly the content of data.
However, what i want is display empty message like --Please select your currency-- by default.
I have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:
<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ ConnectionStrings:PgSqlConnection.ProviderName %>" >
</cc1:pgsqldatasource>
As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.
I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />
I need to pass the control parameter to Sql Datasource in code behind,
<asp:ControlParameter ControlID="DDL_RType" Name="rtype" PropertyName="SelectedValue"
How can I change a parameter to a web part at runtime?
View 1 RepliesI have a user control which I call like this:
<MyNamespace:MyControl runAt="server" ID="foo" /> Is there any way I can determine the ID parameter at run-time and pass it in?
this is my code:
[Code]....
some of my col datatype is nVarchar...
in run time because my value in my table (dt_excel_allRows) are FARSI ; the sequence of my parameter changed and it cant be executed!!!!!
of course the problem is because of FARSI is rtl languges....
i can not user sqlPArameter becuse of some reason....
i think some thing like rtl or ltr can fix my problem....but how?

I want to setup the connectionstring of the SqlDatasource of a dropdown list at runtime, eg. Page Load event. I have install MySQl ODBC driver, System DSN name as "MySQL_Employee" If I have an entry in Web.config:
<connectionStrings>

I want to create a generic page which contains a gridview and sqldatasource. I want to put these two controls on .aspx (C#) page but bind them at runtime. It should have selectcommand, updatecommand, deletecommand and insertcommand. Stored procedures are created for that. Help is needed to make it. .

I'm writing my web application in VB. Is there any way to allow the user to import data from a .CSV file at runtime - that is dynamically? I intend to have the table structures in place, then just have it such that they can append or replace the data that currently exists in the system.
View 2 RepliesWe have an application developed on VS2008 [Asp.Net & C#], in this application we provide the facility to the user to write his/her business logic code. For that purposes we maintained a Businesslogic.cs file where user can write his/her code and our application build it as a BusinessLogic.dll file at runtime.
But the problem is when we introducing Linq statement/code into the BusinessLogic.cs file then it generated compilation error [CS1026 ].
Note that, when we build the dll from VS2008 environment then it working fine with the same code which we write into the BusinessLogic.cs & don't generated any compilation error.
What am i missing or doing wrong here, when i debug, im seeing the selected value in the code behind, but when the page loads, it says the following:
Procedure or function 'Onsite_Report_Procedures' expects parameter '@rptNum', which was not supplied.
<asp:SqlDataSource
ID="SQLOnSiteReport"
runat="server"
ConnectionString="<%$ ConnectionStrings:connectn %>"
SelectCommand="Onsite_Report_Procedures"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:Parameter Name="@rptNum" Type="String" />
</SelectParameters>
</asp:SqlDataSource>

I have a stored procedure with output parameter. I encapsulate it with Table Adapter and BLL. Call it using ObjectDataSource in conjuction with formview, just like the one in Data Access Tutorial. How do I get the output parameter in event INSERTED of the ObjectDataSource in code behind (VB)?
My stored procedure looks like this:
[Code]....
My BLL code looks like this:
[Code]....
We have a stored procedure which creates and returns as output the next value in line:
[Code]....
Yes, the dullards who created this system not only failed to use an identity for the primary key of this table, they then proceeded to add 1 to a varchar column to create the new value, thus insuring it can never be anything but numeric.
Sigh. I'm told we cannot address that obvious deficiency now, and we have to leave the column as varchar. Double sigh.
If I execute this sproc from SSMS, the hh_num variable is returned as expected:
[Code]....
However, when I run it through the application, the parameter I set up as output does not get its Value attribute changed:
[Code]....
I've verified that the "@hh_num" maintains its direction and name through the ExecuteNonQuery call, but its Value remains an empty string.
I want to use parameter in SQL command, Which the following code is better and why?
string id= getId();
SqlCommand cmd1 = cn1.CreateCommand();
cmd1.CommandText = " INSERT INTO std(idStd) VALUES (idStd=id) ";
cmd1.ExecuteNonQuery();
string idF = getId();
SqlCommand cmd1 = cn1.CreateCommand();
cmd1.CommandText = " INSERT INTO std(idStd) VALUES (idStd=@id) ";
cmd1.Parameters.AddWithValue(@id, idF);
cmd1.ExecuteNonQuery();
I´m in need to export datagrids to excel. I found a good solution in C#. I´m a newbie at VB.net. I have got it to work but I´m not familar to set the SQL connection and bind data in C#.
I need to declare my query with a calendar parameter but I have no idea how this should be done in this code.
Either, how do I set parameters into the C# code or how can I set a SQLDATASOURCE in the ASPX file and still run all code.

i am developing an application using asp.net and backend server is SQL SERVER 2005.
in my application i have 12 regions. from that 12 regions user will select any of them.
if user select 1,2,3 then i have to pass this string to IN clause
for that i have storedproc like
create procedure sp_updateDistributorContractforAllRegions (
@unitprice float,
@region varchar(50)
)
update employee set UnitPrice=@unitprice where regionid in (@region)
end
GO
here regionid datatype in employee table is INT.
from code behind i am adding the parameter as 1,2,3.when i run the query it gives the error as
Conversion failed when converting the varchar value '1,2,3' to data type int.
