DataSource Controls :: Use A Variable In Front Code?
Jul 8, 2010
I'm making a page with a DropDownList (called ddlSupp) that contains several suppliers, and I populate it with an SqlDataSource, all in front code.
In another part of the page I make a CheckBoxList, and populate it again with an SqlDataSource. The select command of the SqlDataSource is a procedure call to my MySQL database. However, what the CheckBoxList gets populated with depends on who is selected in ddlSupp. How do I make a variable in front code that will take the value from ddlSupp and populate my checkbox accordingly?
Here is my code:
[Code]....
I get a MySQL error at (<%$ddlSupp.SelectedValue %>) so I know the wrong value is being passed into the query. How can I fix this?

I have a question related to <asp:SqlDataSource's SelectCommand. How to pass a querystring like <%# Eval("PhotoID") %> in the selectCommand. The whole frontend code is attached. I put
<%# Eval("PhotoID") %> and the photoid gets printed in the page.
<%# Eval("PhotoID") %> is the current displayed picture's PhotoID.
I want to pass this PhotoID or I want to pass <%# Eval("PhotoID") %> to the select command dynamically. I have tried the following approaches:
1) <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:aspnetdb %>" SelectCommand="SELECT UserName, commentDesc, uID FROM photo_comment_view Where pID = @pID"> <SelectParameters><asp:Parameter Name="pID" DefaultValue="7" /></SelectParameters> </asp:SqlDataSource> The above works but it gives only information about PhotoID 7, but there are other photos; How to set pID's value to <%# Eval("PhotoID") %> in ASP .NET's frontend page? then I also tried,
2) <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:aspnetdb %>" SelectCommand="SELECT UserName, commentDesc, uID FROM photo_comment_view Where pID = <%#'Eval("PhotoID') %>"></asp:SqlDataSource> Gives Parser error: Parser Error Message: The server tag is not well formed.
What I should do so that I can pass current PhotoID to SelectCommand? The frontend code:
<%@ Page Language="VB" MasterPageFile="~/Default.master" Title="Your Name Here | Picture Details"
CodeFile="Details.aspx.vb" Inherits="Details_aspx" %>
<asp:content id="Content1" contentplaceholderid="Main" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div class="shim solid"></div>
<div class="page" id="details">
<%--Update Panel Here--%>
<asp:UpdatePanel runat="server" ID="updatepanel">
<ContentTemplate>
<asp:formview id="FormView1" runat="server" datasourceid="ObjectDataSource1" cssclass="view"
borderstyle="none" borderwidth="0" CellPadding="0" cellspacing="0" EnableViewState="false" AllowPaging="true">
<itemtemplate>
<div class="buttonbar buttonbar-top">
<a href="Albums.aspx"><asp:image ID="Image1" runat="Server" skinid="gallery" /></a>
<asp:ImageButton ID="ImageButton9" Runat="server" CommandName="Page" CommandArgument="First" skinid="first"/>

to bring a browser window to the front based on some action? I'm writing an intranet application that monitors for new messages to be received over our satellite link from our fleet, but our dispatchers already have busy screens. Is there a way to bring a browser window to the front via javascript or code behind?

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="<%$ 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 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" />

I can get userName from HttpContext.Current.User.Identity.Name but how do I pass that to the objectDataSource?

I've done some SSIS package work in the past, but am by no means an expert.
I want to use an SSIS package to do the following:
1. Get the file name of the newest file in a windows folder (using a filename template like his: filename_ *.txt where the * part is always a date in the format of yyyy-mm-dd.
2. Use that file name in later portions of the SSIS package by reading the file and transferring data from it to a SQL table using a Data Flow task.
and use the result (which should be the name of the newest file) to open that file and pull data out of it and into a 2nd SQL table. I admit, I'm not sure how to use the dynamic result of this SELECT query as the file name in a flat file connection manager.

I need to use a global variable as a parameter for the SqlDataSource element. I capture the user Name when he/she logs in:
Public UserName As String
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
UserName = Page.User.Identity.Name
End Sub
Then, I need to use the UserName to search the SQL DB and show only logged user personal information.
SelectCommand="SELECT * FROM [Member] where [UserID]= UserName"
What is the sintaxe to use a global variable into the SQL Select Command?
