DataSource Controls :: Getting Error On Attempted Databind Call To DataList1 With Nested SqlDataSource Tool

Jan 26, 2011

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.

And the code behind....

DataSource Controls :: Catch An Error From A SqlDataSource Stored Procedure?

Sep 27, 2010

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?

DataSource Controls :: GridView - Control Parameter Error Using Oracle SQLDataSource

Aug 2, 2010

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.

DataSource Controls :: SQLDatasource FilterExpression Error - Input String Was Not A Correct Format

Nov 25, 2010

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]....

Forms Data Controls :: When To Call DataBind On GridView

Sep 2, 2010

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...

DataSource Controls :: SqlDataReader And The Invalid Attempt To Call FieldCount Error?

Mar 30, 2010

I 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:

Forms Data Controls :: Repeater DataBind Not Updating Items In Datasource

Jan 28, 2010

Here 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.

[Code]....

and code bedind

I Tried with both the Repeater Item Command and each LinkButton Event to see if it would make any difference, but none worked

Forms Data Controls :: GridView - Databind To A Collection Within A Custom Datasource?

Jun 14, 2010

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)?
