View 1 RepliesI 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.

View 1 RepliesI have an ODS control populating a Telerik grid. The ODS definition is pretty simple. It's set to call a method on a static class that has one parameter (entityID). I set this parameter in the OnSelecting event. When I test this, the world is a happy place and all is fine.
Then, I pass a query string to the page (which sets various unrelated values for the page, we'll say parameters X and Y). The page call's Telerik's radgrid.Rebind() event. When this happens, an error is throw from the ODS saying that the underlying method (the static data procedure) does not support parameters X and Y.
So, why is ODS thinking it should be using any querystring values at all when I have explicitly set the entityID parameter (of type Asp:Parameter)? How do I stop this from happening?
The Html:

The OnSelecting:

I see this odsList_OnSelecting being hit and the inspection of e.InputParameters only contains my expected single entry.
this has to be a simple thing but I am missing it

View 1 RepliesI 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 have the need to display a date in this format: dd/mm/yyyy. This is actually being stored in an ASP.NET textbox and being used as a control parameter for a select on the GridView. When the query is run, though, the date format should change to 'd M y' (for Oracle). It is not working. Can someone tell me what I'm doing wrong? Right now I am pushing the "new" format to a invisible label and using the label as my control param:
$(document).ready(function() {
//datepicker for query, shown traditionally but holding an Oracle-needed format
$('[id$=txtBeginDate]').datepicker({ minDate: -7 , altFormat: 'd M y' });
//get alt format
var altFormat = $('[id$=txtBeginDate]').datepicker("option", "altFormat");
//set date to be altformat
$('[id$=lblActualDate]').datepicker("option", "altFormat", 'd M y');
});

I have a SQLDataSource control that is calling a database stored procedure, and passing quite a large number of paramaters, and the stored proc returns records that populates a gridview control. When I walk through the code behind to determine the values being passed, is there any way that I can see exactly how the parameters are being formated and passed to the stored proc?
View 2 RepliesI 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.
View 2 Replieswhat is the disadvantages of using SqlDataSource Control? apart from flexibility and more control on the retrieved data ;why most of the web developer prefer using code behind (db connection) instead of SqlDataSource Control?
View 5 RepliesI 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 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
ErrorCode=-2147217913
Message="Data Type Mismatch." [code]....
what is wrong with both examples above?I'm adding values to all fields in the table, except for the ID field, ofcouse.
