DataSource Controls :: SqlDataSource - Parameter For IN() Clause

Apr 30, 2010

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 ?

DataSource Controls :: Sqldatasource Insert Method - Copy Data To The Other Datasource By Selecting Checkbox

Feb 25, 2010

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?

DataSource Controls :: All Parameters Null In Update Of SQLDataSource?

Sep 23, 2010

I have a FormView which is bound to an SQLDataSource. When a user clicks on a save button the form, I need to write any changes made to the FormView back to the table.

I have a Stored Procedure on my MSSQL 2005 database that should be executed when the user clicks on the save button.

It appears the Update is firing, but when I trap the DbCommand object in the SQLDataSource's 'Updating' event, all of the parameters that should be passed to the Stored Procedure are coming through as NULLs. Consequently, the Stored Procedure isn't updating anything.

In the click event of the save button I'm explicitly firing the SQLDataSource's Update method:

[Code]....

The parameters in the SQLDataSource <UpdateParameters></UpdateParameters> section appear to be correct.

Can anyone give me an idea on what to investigate to figure out why it appears the Update is only picking up NULLs?

DataSource Controls :: SqlDataSource : Make Condition Only If Data Is Not Null?

Feb 21, 2011

I have a SqlDataSource connected to database and use a parametrized query to fetch out data.Query has got a very large varchar field on which i have to perform a search.To make search, i have 2 combobox and a textbox organized in this way

MAIN CATEGORY (combobox)-> CATEGORY TYPE(combobox) -> MODEL(textbox).

Based on main category choose, category type is filled from database. At last, it's added a "nothing" combobox item.Now i should search into big varchar field adding category type condition but, if nothing is specified, i should make identical search like all combobox value are selected. How should i, in your opinion, make this using SqlDataSource?

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>

ConvertEmptyStringToNull="True"
DefaultValue="0"
Direction=" InputOutput "
Name="pAppId"
SessionField="app_id"
Size="integer"

Please review the stack trace for more information about the error and where it originated in the code.

Forms Data Controls :: Handling Null Values In Detailsview / Cannot Insert The Value NULL Into Column

Nov 27, 2009

I have a detailsview bound to a datasource where all columns are set to not allow null values. Now, I want to make sure that the user does not try to enter an emtpy string when inserting a post in the detailsview. So I set all the fields to ConvertEmptyStringToNull="false".

I also added a RequiredFieldValidator for the EditTemplate TextBox1.

All of this works when I use a Gridview (for updates). But in the detailsview, I get the errormessage:

"Cannot insert the value NULL into column".

So why isn't ConvertEmptyStringToNull="false" and RequiredFieldValidator working in the detailsview? As far as I could figure, these should have made sure it wasn't possible to try to insert a null value in the SQL Server database...

Forms Data Controls :: Using AND / OR Parameter From A DropDownList In A SqlDataSource

Jan 29, 2010

I am facing a small issue in using a DropDownList that has only two values (AND and OR) which i want to use to configure a SQL Query in a SqlDataSource. How can i use this thing by passing the value in a SqlDataSource Select Query in such a way to Bind the Result to a GridView. I want something like this -

SELECT [somefields] FROM instinvoice WHERE Namen = @Namen @Option InvoiceNo = @invoiceno where @Namen is from a DropDownList and InvoiceNo is from a TextBox

I m having a problem in specifying this @Option parameter from a DropDownList which contains only two list items - AND and OR. On the Basis of the Selected Value from this DropDownList i want to execute query like

SELECT [somefields] FROM instinvoice WHERE Namen = @Namen AND InvoiceNo = @invoiceno

or

SELECT [somefields] FROM instinvoice WHERE Namen = @Namen OR InvoiceNo = @invoiceno

Using the Query with @Option gives me a Parsing Error. Why is that so. How can I implement this scenario.
