I have an objectDataSource which uses my stored procedure GetNotifications
And my GridView is bound to that objectDataSource
the only problem is that my stored procedure requires the variable @UserName and then returns the values for that username, but I do not know how to pass the variable to the objectDataSource, does anyone know the code for this?
I can get userName from HttpContext.Current.User.Identity.Name but how do I pass that to the objectDataSource?

I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:
[Code]....
<truncated>
What I want is to grab the screenshotId from the SqlDataSource when the usp_GetOrderDetails stored proc gets called and populate it into a field on the page called screenshotId. I then want to use this screenshotId to get an image from the database based on Id. populating the screenshotId field. How do I do this - do I need to have something like OnDataBound or something like that?

I'm trying to add new rows to a data table and then use the sqldataadapter update method bu fund some problems. First, I written this code:
[Code]....
Excuse me but the most part of variable are in italian, however I think it is possible to understand how does it work. If I execute this code I obtain this error:
System.InvalidOperationException: Update requires a valid InsertCommand when passed DataRow collection with new rows.
After this I added these lines of code just above the last line:
SqlCommandBuilder cb = new SqlCommandBuilder(adapter);
adapter.InsertCommand = cb.GetInsertCommand;
and I obtained this error:
Cannot convert method group 'GetInsertCommand' to non-delegate type 'System.Data.SqlClient.SqlCommand'. Did you intend to invoke the method?

I have a database linked to a calendar. I had a peice of code that retrieved dates from a database and populated the calendar. I wanted to tidy up my code using stored procedures (they seem neater & i assume there's a benefit somewhere). so i came up with this, however it's not working. The calendar displays, but it's not being populated with the database entries. The SqlCommand & SqlParameter I have working elsewhere in my code; as with the SqlDataAdapter (which also worked before i tried to conver to a storedprocedure!) but combining these three (SqlCommand, SqlParameter & SqlDataAdapter) seem to be causing me problems.It's probably something stupid but if someone could take a look and point me in the right direction,

I'm trying to create a class, DataCommon, to contain all my SQL Data manipulation functions. I've created a Subroutine called Init that initializes a SQLDataAdapter:
[Code]....
From my other classes I am creating an instance of DataCommon, calling Init, and calling another subroutine in DataCommon that pulls data from SQL and loads the data into my dataset. This part is working great -- no problems at all. I'm loading three different Datatables in the Dataset with no issues.
At this point, I'll perform my various manipulations on the datatables -- add/delete/modify rows -- again with no problems. All of this is creating postbacks...and this is where my problem begins. After I've done all my manipulations to the data and am ready to update my SQL tables, I have to re-initialize my SQLDataAdapter. I thought I could do something like:
[Code]....
But I get the error: Exception inserting Class. Thread was being aborted.
In my initial data load from SQL, each datatable is getting loaded from a single SQL table, so I was hoping to use the autogenerated Update/Insert/Delete statements by the SQLDataAdapter. As a test, as soon as I filled the dataset initially, I added a new row to one of the datatables and used the SQLDataAdapter.Update() method before a postback occurred, and it worked perfectly.
So, with all that being said, I guess my question is, how do I reconnect the table mappings between my SQLDataAdapter and dataset to autogenerate the updates after a postback occurs? I've tried researching this, but I get confused after reading about FillSchema vs TableMappings vs everything else I've read about.

trying to merge two sets of data from a SqlDataAdapter and an OleDataAdapter and then populate a gridview on a button click. If I run just the SqldataAdapter on its own the grid populates as expected. This also applies to the OleDataAdapter. The problem arises when I try to merge the two. I get an empty table, hence dt3 is not populating. The code i'm using is below.Does anyone know why this doesn't work?

This may be elementary user control stuff, but I can't get it to work.
How can I pass the Membership.GetUser.UserName variable (or any variable) through a user control parameter at load time?
[Code]....
The only thing that I was able to do was to create the User Control object in the code behind and then add it to the page. Although that works, it doesn't seem like the correct way to program.

I query the database to get the VideoName and VideoURL of the videos held in my database (Videos saved on the file system with their location stored in the database) then bind the query results to a repeater with the following code
protected void Page_Load(object sender, EventArgs e)
{
// Variables declaration
string strConnString = ConfigurationManager.ConnectionStrings["vidConnectionString"].ConnectionString;
SqlConnection sqlConn = new SqlConnection(strConnString);
SqlCommand sqlcmd = new SqlCommand("SELECT [VideoName], [VideoURL] FROM [Video]");
SqlDataReader sqlReader;
sqlConn.Open();
sqlcmd.Connection = sqlConn;
sqlReader = sqlcmd.ExecuteReader();
VideoRepeater.DataSource = sqlReader;
VideoRepeater.DataBind();
sqlConn.Close();
}
and put a hyperlink into the repeater to list all the VideoName's this works fine but I want to pass the VideoURL to the next page I am using NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" but when I try and load the Page I get the error saying The server tag is not well formed. the whole repeater code is
<asp:Repeater ID="VideoRepeater" runat="server" >
<ItemTemplate>
<asp:HyperLink ID="VideoLink" NavigateUrl="PlayVideo.aspx?VideoURL='<%# Eval("VideoURL") %>'" runat="server"><%# Eval("VideoName") %></asp:HyperLink>
</br>
</ItemTemplate>
</asp:Repeater>
I'm sure i've just got the hyperlink navigateURL wrong put not sure how else to pass the VideoURL variable

For example:
<asp:HyperLinkField Text="Edit" NavigateUrl="EditPage.aspx?var1=Variable1&var2=Variable2" />
I realize this can't be done through the page's mark up, at least I think this is so, but if someone could explain the easiest way the concept could work I'd be very appreciative. Basically, I just need a user to be redirected to a page with more than one variable in the url. If you are unclear with what I'm asking don't hesitate to ask me to explain a little better.

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" />
