I am getting error on attempted Databind call to DataList1 with nested SqlDataSource tool after attempting to update or delete a record.
The SqlDataSource control 'sqldsfilelist' does not have a naming container. Ensure that the control is added to the page before calling DataBind.
Here is the aspx page code.

I'm using MikesDotNettings([URL] code mentioned: Bind Data From a SQLDataSource to a Label, and I'm getting this error:
"An SqlParameter with ParameterName 'ID' is not contained by this SqlParameterCollection."
This is what I have, I'm using my own data to try and populate the labels:

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 receive the error (Both DataSource and DataSourceID are defined on 'DataList1'. Remove one definition) in the following code. Could anyone help me sort this out. I do not have anything named DatasourceID that I can find.

I have a problem with inserting some records into an access database using the sqldatasource control.
Here is Ex 1:

Ex 2:

I have tried both examples above, and some variants of them, but I'm getting errors.
With Ex 1 I get:
System.Data.OleDb.OleDbException was unhandled by user code

what is wrong with both examples above?I'm adding values to all fields in the table, except for the ID field, ofcouse.
I am not able to figure out why I am getting the null error at SqlDataSource10.Insert(); I tried running through break points and i checked the Insert statement and it has all the required values .. but I get error saying it cannot insert null into NrNarrativeDays.

I have a stored procedure that creates a dynamic query. Sometimes the query is not built because there are no elements in the dynamic query. When the aspx page loads the SqlDataSource throws an error that the query is malformed. How can I catch this error, and handle it with a default message, before it returns the error to the aspx page?

how can i call the event in another event.like Button Click event.
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. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: Oracle.DataAccess.Client.OracleException: ORA-01036: illegal variable name/number
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:
[Code]....
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]....

So I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...

I have a recordset in a gridview that comes from an outer joint that creates null values in the recordsetWhen I write to the database using stored proc defined in datasource I get dbnull error.I'm trying to process the onDeleting event in the code behind but don't know what to write or if that's the best wayI need to call a stored proc and if the last parameters value is null then the stored proc does one thing, if it's no null it does something else.However DBNull doesn't ssem to be working.
View 1 RepliesI have several methods where I return a SqlDataReader to populate Gridviews, Listview, etc. I get random "Timeout expired" errors regarding connection pooling, so I decided to add using{} to my methods. The lack of using is a carry over from my more beginner days.Below I included the before and after code. The after code always gives me the "Invalid attempt to call FieldCount when reader is closed" error. I have tried various combination of using{}, but ALL result in the same error.What am I doing wrong? Also, from the code below what is the best way to structure this code to ensure no connection leakage?Before:

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 am getting following error on gridview.databind() Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack , ThreadAbortException,it was working fine and suddenly getting error, i don't what's problem is?
View 6 Repliesam having trouble figuring this one out. Am using stored procedure and using databind for the gridview . i got the codes off other sites.

View 2 RepliesHere is the situation I have, I have a repeater inside a Usercontrol. The datasource is a IEnumerable<Investor> Exposed through a UserControl's Property. I have overridden the UserControl's databind event to set the Repeater Datasource before databinding the repeater. When it's not a postback, it databinds find and the events on the repeater item's controls fires up fine. But there is one event on repeater items (Delete Investor) which call back the DataBind of the UserControl after removing the Investor from de datasource. When this Event is called, it does all the work (deleting the investor and so on...) calls back the usercontrol's databind but when (within the usercontrol databind) the repeater is databinded again, the repeater items doesn't update (repeater items for investor not on the DataSource anymore still appears). My ItemDataBind doesn't even fire by then.

I Tried with both the Repeater Item Command and each LinkButton Event to see if it would make any difference, but none worked
I'm trying to databind my GridView to a custom datasource where one of it's members/fields is a collection.
Custom object Entry
public List<EntryHour> Hours { get; set; }
In practical terms, one row consists of some normal text fields which is easy to handle. However, the Hours field is the nut to crack.
How do I, in the GridView markup bind my textfields in question to the Hours field (which consists of 7 items allways)?
