I am trying to tie a sqlDatasource to a Stored Procedure. The stored procedure looks like...
[Code]........
i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
I have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied
SELECT * FROM [this_table] WHERE username = @username
and if gender supplied
SELECT * FROM [this_table] WHERE gender = @gender
and if both supplied
SELECT * FROM [this_table] WHERE username = @username AND gender = @gender
I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each
if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.
I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.
On my SqlDataSource my InsertCommand looks like this:
InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City,
@State, @Country, @CompanyName, @Active, @PasswordHash) END"
This works as expected: If the username is unique, the row is created.
If the username already exists, the row is not added.
The problem is, if the row already exists, the insert is rejected but the user is not notified.
So my question is, is there a way I can notify the user?
Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.

If I have a SqlDataSource like this one, is it possible to add a DataRelation in the sqldatasource? Or do I need to create a DataSet and add the Relation in CodeBehind?

SelectCommand="SELECT * FROM table">

I'm using MikesDotNettings([URL] code mentioned: Bind Data From a SQLDataSource to a Label, and I'm getting this error:

I need to assign the values to a labels (strings) as I need to use them for another caluculation.Can you or anyone looking at this figure this out?
I have an SqlDataSource query that should use an input parameter for multiple integer values, like:
select * from table1 where TableID IN (1,2,3,4,5)
->
select * from table1 where TableID IN (@IDValues)
How do I do that ? Default parameter settings won't work, returning "invalid integer value" . I suppose that parameter should be passed as some kind of array that SQL recognizes as multiple integer values , but what's the correct way of setting this ?
i want to ask how to i set variable in asp:sqldatasource in sqlcommand in asp.net c#....
This is my code
asp.net
<dx:ASPxListBox ID="lsAssignToko" runat="server" DataSourceID="SqlDataSource6"
TextField="NAMA" ValueField="ID" AutoPostBack="true"
EnableCallbackMode="True" SelectionMode="CheckColumn"

ProviderName="<%$ ConnectionStrings:Ora2010.ProviderName %>"
SelectCommand="SELECT ID, NAMA FROM REF_TOKO WHERE ID IN ( :inTOKO ) ORDER BY NAMA">
<SelectParameters>
<asp:SessionParameter Name="inTOKO" SessionField="inTOKO" Size="200" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
c#
string dummy = "";
string data = "";
string inTK = "";
string inTOKO = "";
//string inTOKO1 = "";
int pot;
for (int i = lsToko.SelectedItems.Count - 1; i >= 0; i--)
{
string tok = lsToko.SelectedItem.Text.ToString();
data = lsToko.SelectedItem.Value.ToString();
dummy = dummy + "" + data + ",";
int index = lsToko.SelectedItem.Index;
lsToko.Items.RemoveAt(index);
}
if (lsToko.SelectedItems.Count <= 1)
{
inTK = dummy.Length.ToString();
pot = int.Parse(dummy.Length.ToString()) - 1;
inTOKO = dummy.Substring(0, pot);
}
Session["inTOKO"] = inTOKO;
the problem is where in my variable inTOKO consist of couple of value...
Example
while variable inTOKO = one value success but while value inTOKO = two value error
inTOKO = 1101111 => success
inTOKO = 1101111,1211321 => not success
Im currently filling a dataset using an SqlConnection and a SQLDataAdapter:
[Code]....
This method is causing other sql connections to timeout. What I would like to do is an SQLDataSource to fill the dataset. Is this possible?
It seems really easy to output a sqldatasource into a table but really hard to output a sqldatasource into a variable.
View 2 RepliesI have an editable grid where user can add/edit data. They also have the option to load previously entered data from last month. When the user then clicks save, i want to readd this newly modified data as a new record for this month. So basically I want to call the insertcommand, but it does not work. My 'save' method just 'updates' the records.

I use MySQL database and SqlDataSource controls. I generate update and insert queries in my code behind.how I can get a list of columns from the SqlDataSource control?
View 2 RepliesI have three controls a textbox, a drop down and a check box on a webform as below;
[Code]....
I have an SqlDataSource defined and configured with SELETC and UPDATE commands as below;
[Code]....
How can I;
1. Query the SqlDataSource for a specific record (ie ApplicantID = some value) and then read the selected data in the three controls on the webform?
2. Update user changes from the three webform controls back to the SqlDataSource?
I need to run a query on server1.database1 where subquery meets criteria on server2.database2. Here's my code:
[Code]....
I tried replacing connectionstrings:connectionstring2 with server2.database2.dbo.scheduledvisits but it didn't know where to look to find that besides by using connectionstring1.
I want to retreive some data from an SqlDataSource using it's Selected event I've tried
DataView dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty)
but here it's going into in infinite loop and then it gives me an StackOverflowException error in ASP.Net Development Server (my dev machine) and if I publish to IIS it requires me an user name and password to connect to server and gives an InternetExplorer error "Sys.WebForms.PageRequestManagerServerErrorException. An unknown error ... status code returned was 400. The SqlDataSource is in an UpdatePanel. Maybe this is why I get this.
I am using SqlDataSource control that retrieves information based on a city value from another control (textbox) on the page entered by the user.
[Code]....
The query works fine when the user enters a name of a city. However, if I leave the textbox blank and enter nothing, no records are returned by the query.I need all records to be returned when user leave the textbox blank and there is no value of the city.How to do that?is there a default value can do that?
I have a strange problem...I am programatically adding an SQL SELECT query to my SqlDataSource that my GridView is bound to. If I use the follwing statement it works fine:
[Code]....
But if I use the following one, the gridview fails to load. The only way that this is different is it uses RTRIM and CAST on one of the fields:
[Code]....
I don't understand why this can be. If I try the statement exactly how it is in the query builder and run it it returns the rows no problem.
