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. Exception Details: Oracle.DataAccess.Client.OracleException: ORA-01036: illegal variable name/number

DataSource Controls :: DBType Error Type 'System.Web.UI.WebControls.Parameter' Does Not Have A Public Property Named 'DbType'

Feb 28, 2010

I had to format my hard disk and reinstall the Visual Studio 2005 Enterprise and SQL 2005 Standardprograms.

While my program worked perfectly before and still works ok on my second computer, I get the following error message on the formated computer:

Parser Error Message: Type 'System.Web.UI.WebControls.Parameter' does not have a public property named 'DbType'.

Source Error:

Line 82: <asp:Parameter Name="Olho" Type="String" />
Line 83: <asp:Parameter Name="image" Type="String" />
Line 84: <asp:Parameter DbType="Date" Name="inicio" />
Line 85: <asp:Parameter DbType="Date" Name="termino" />
Line 86: <asp:Parameter Name="pageId" Type="Int32" />

Source File: /0_oserigrafico/Default.aspx Line: 84

In this case I use a datasource control for a datalist and the parameter list is being built ba the system.
The DBType is created for the smalldatetime feild

how do I add the property named 'DbType'.

Forms Data Controls :: Dropdownlist Selectedvalue Does Not Exist Error?

Mar 2, 2011

I have a drop down list inside a formview control's edititemtemplate and itemtemplate. The dropdown list is not bound to a data source. I am hard-coding the listitems for the drop down list. The formview is bound to a datasource. All I want to do is set the selectedvalue of the dropdown to what is in the record from the database. But I keep getting the error.

<asp:formview .....>
<edititemtemplate>
.... //some other controls like textboxes that are correctly bound and display the value from the datasource
<asp:dropdownlist ID=myddl runat=server cssclass=myclass selectedvalue='<%# eval("mychoice") %>'>
<asp:listitem value='0'>I dont know</asp:listitem>
<asp:listitem value='1'>Yes</asp:listitem>
<asp:listitem value='2'>No</asp:listitem>
</asp:dropdownlist
.....//rest of the edititem controls that display correctly.
</edititemtemplate>

Just for kicks, I added a textbox and set it's value to eval("mychoice") as well and it correctly prints 0,1 or 2. So, I know that there is no illegal value coming back from the datasource. It seems as something with the timing of events - when the listitems are getting bound to the ddl. The error I get is - "myddl has a selectedvalue which is invalid because it does not exist in the list of items".

DataSource Controls :: Filter - Select Date In Ddl And Use Selectedvalue In Gridview SelectCommand

Nov 7, 2010

I've got a gridview which works fine. I use dropdownlists which are filled with distinct values of the columns. So when I select an item in a drompdownlist the gridview refreshes based on the selected value. When I have a column which uses string values, I can start the filter with a default % value to use in my select paramaters. But when I have a date column, I can't use that. I use a datasource for the gridview and I prefer to leave codebehind out if this is not needed. Now I use >= in my gridview select to show all rows. but I want to use only = to make the filter work correct when I select a date in the ddl and use the selectedvalue in the gridview selectCommand

<asp:DropDownList ID="ddlUpdateDatum" DataSourceID="dsPopulateUpdateDatum"
AutoPostBack="true" DataValueField="UPDATEDATE" runat="server"
CssClass="selectinput" AppendDataBoundItems="true">
<asp:ListItem Text="All" Value="01/01/1900"></asp:ListItem>
</asp:DropDownList>
<asp:SqlDataSource ID="dsPopulateUpdateDatum" runat="server"
ConnectionString="<%&#36; ConnectionStrings:GAMSYSTEMSqlServer %>"
SelectCommand="SELECT DISTINCT(UPDATEDATE) FROM [messages] ORDER BY UPDATEDATE ASC ">
</asp:SqlDataSource>
And I use this in the gridview datasource:
<asp:SqlDataSource
runat="server"
ID="dsGridview"
ConnectionString="<%&#36; ConnectionStrings:DBSqlServer %>"
SelectCommand = "SELECT * FROM [messages] WHERE AND UpdateDatum >= @UpdateDatePar ORDER BY UpdateDatumDESC"
>
<SelectParameters>
<asp:ControlParameter Name="UpdateDatePar" ControlID="ddlUpdateDate" PropertyName="SelectedValue" Type="string" />
</SelectParameters>

DataSource Controls :: Variable Connection String Parameter In A DataSource Control

May 20, 2010

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="<%&#36; ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%&#36; 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.

DataSource Controls :: Access Property Of Object As Session Variable As Declarative Datasource Parameter Value

Oct 27, 2010

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:

[Code]....

However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />

Setting SelectedValue For One DropDownList Also Updates The SelectedValue For Another DropDownLIst

Jul 21, 2010

I have a WebForms page that has two DropDownList controls on it that both contain a range of temperatures from 60-80 degrees, one for heating the other for cooling. They are declared in the .aspx as:

<asp:DropDownList ID="heating" runat="server" />
<asp:DropDownList ID="cooling" runat="server" />

The values for each list are populated in the code-behind using:

for(int i = 60; i <= 80; i++)
{
var listItem = new ListItem(i + " degrees", i.ToString());

heating.Items.Add(listItem);
cooling.Items.Add(listItem);
}

When I try to set the selected value for each DropDownList using the values in an object containing data loaded from the database using:heating.SelectedValue = myHome.avgHeatingTemp.ToString();
cooling.SelectedValue = myHome.avgCoolingTemp.ToString();

The SelectedValue for both lists is set first to the value in myHome.avgHeatingTemp, then to the value in myHome.avgCoolingTemp. Heres what the values are for each variable after each step of the process of setting the SelectedValues:

Initial State
heating.SelectedValue: 60
cooling.SelectedValue: 60 [code]....

Indicate Error Once There's An Unexpected Parameter?

Mar 30, 2011

My ASP.NET application will have to handle HTTP GET requests that will have the following URL format: [URL] currently the requirement is to validate that there're no parameters in the query string except id and indicate an error like "unknown parameter P passed". Is such requirement a good idea? Will it interfere with some obviously valid cases of using the application I haven't thought of?

DataSource Controls :: Output Parameter Not Getting Value?

Jul 12, 2010

We have a stored procedure which creates and returns as output the next value in line:

[Code]....

Yes, the dullards who created this system not only failed to use an identity for the primary key of this table, they then proceeded to add 1 to a varchar column to create the new value, thus insuring it can never be anything but numeric.

Sigh. I'm told we cannot address that obvious deficiency now, and we have to leave the column as varchar. Double sigh.

If I execute this sproc from SSMS, the hh_num variable is returned as expected:

[Code]....

However, when I run it through the application, the parameter I set up as output does not get its Value attribute changed:

[Code]....

I've verified that the "@hh_num" maintains its direction and name through the ExecuteNonQuery call, but its Value remains an empty string.
