I have one SqlDataSource control as DataSet with enable caching in one page aspx. Filtering is applied to this SqlDataSource control, so that the page always returns one record data.
My question: How to get the record data value from SqlDataSource control (one record data value) and store it as String variable?
I need to get one record from rows. For example:
DB:
id, name, age, nick, gender , etc...
1, John, 18, gobb, M, ....
2, Andrew, 22 , AND, M, .....
3, Simon, 35, Lucky, M, ......
How to Get name (For example Simon) from DB and enter it into label? Or perhaps this is impossible?
I have a sqlDatasource with a SelectParameter ControlParameter linked to a dropdownlistIs there an a way to select all records like *
[Code]....
So I can select records by year, but is there a value that will select all records for the @Year Parameter so I can display all records?
I know this sounds odd. I have a SQL DB that I am pulling data from. I have to some math functions to get a percentage. So I am pulling all the data in my code and building a data table with the results. I am then trying to pass this into a chart control that I have, but it fails because the data source is not correct for the chart control. I know that the chart control will accept a SQLDataSource control as a data source because a built a example with it before using it in my project.So my question is how can I use the Data Table as a data source for a SQLDataSource Control? Or is there a way I can pull the data from my DB andapply the math needed in a stored procedure or something similar that I could create the procedure on my SQL server then add a SQLDataSource control to my page and use the stored procedure as the source for the SQLDataSource Control.

My insert is adding a record to the database in the call to the stored procedure in SQL Server, but a -1 is returned - Shouldn't it return 0 if the insert/update was successful?
Result = myCommand.ExecuteNonQuery();
I get the Erorr: Input String was NOT a correct format.
The first three controlparameters are STRINGS and they work fine.
However the last two populate the controlparameter from text boxes that can only accept numbers and decimal point.
First the text boxes for {3} and {4} string parameters in the SQL filterexpression:

And then the SQLDatasource control parameters[Code]....
The last two control parameters are the ones is question as they feed {3} and {4} parameters in the filter expression, NOTICE how I set the type="double".The data input is expected to be like 152.25 or 3.6 or 4 etc,So why am I getting this error: [Code]....

I am going to use DetailsView control for the first time and before using it I thought I would like ask this question. Instead of using the SqlDataSource Object/Class Can i have my class to most of the functionality?In short I donot want to use the in build Sql Data Source control rather would prefer to write my own. Is it possible (I know it must be!) to write the custom SqlDataSource class.

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 an user control placed on a content page. The content correctly receives the session variables. In the user control I have the following
1. The pageload fires and the text box is correctly set.
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (Session["app_id"] != null)
{
txtAppId.Text = Session["app_id"].ToString();
}
</script>
2. I have datagrid in the usercontrol which has a binding variable tied to a control parameters as follows
<asp:SqlDataSource ID="SqlDataSourceMain" runat="server"
ConnectionString="Myconnectionstring"
ProviderName="MyProvider" SelectCommand="select
last_name,first_name
from applications
where (id = to_number(:pAppId))">
<SelectParameters>
<asp:controlparameter name="pAppId" controlid="txtAppId" propertyname="Text" />
</SelectParameters>
<SelectParameters>
<asp:controlparameter name="pAppId" controlID="txtAppId" propertyname="Text"
Direction="InputOutput" Type="Int32" ConvertEmptyStringToNull="True" />
I tried the following, same error
</SelectParameters>
<asp:SessionParameter
ConvertEmptyStringToNull="True"
DefaultValue="0"
Direction=" InputOutput "
Name="pAppId"
SessionField="app_id"
Size="integer"
Type="String" />
</asp:SqlDataSource>
For some reason the select parameter pAddId is getting set to null and get the following error when the content page is loaded If I hard code the value it works RA-01036: illegal variable name/number Description: An unhandled exception occurred during the execution of the current web request.

I am trying to tie a sqlDatasource to a Stored Procedure. The stored procedure looks like...

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 have a bound data field, a detailsview, one of the records I have formatted to currency in the item template. Yet when I go to delete a record, I get a error message "Input string was not in correct format". Take away the formatting and the page runs fine. I tried changing the datatype from int to money, it makes no difference.
View 3 RepliesI want to retreive some data from an SqlDataSource using it's Selected event I've tried

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.
