I'm attempting to load a GridView dynamically on a button is pressed.The gridview has AutoGenerateColumns="True" (set in skin definition) and has a declarative column definitions as follows:
<asp:GridView runat="server"
SkinID="GridViewDetail" ID="gvReport"
DataKeyNames="dateofcompletion">
<Columns>
[code]...
This all works fine the first time, but as soon as I select a different ddlCampaign item, it throws the"A field or property with the name 'FieldName' was not found on the selected data source" ERRORI kinda understand that it has retained the column mappings from the previous datasource assignment/binding and because the new datasource has different column headings it is throwing the error. What I can't seem to achieve is a clear or reset of defined gridview columns before adding the new columns. I cannot clear all columns because part of the GV defn is declarative.e.g.
gvReport.Columns.Clear();
gvReport.AutoGenerateColumns = true;
I have also tried clearing the previously added columns before new assignment/binding but it gives the same error.e.g.
for (int i = 2; i < gvReport.Columns.Count; i++)
{
gvReport.Columns.RemoveAt(i);
}
I am trying to bind the XML data to a datagrid from an XML file. I don't know why I am getting the message: "A field or property with the name 'User_x0020_Name' was not found on the selected data source."

How can i show "No data found" if data is null in RDLC reports ?
As i have put a table inside the report.rdlc and i want to show text "No data found" if there is null data or empty report.
I am trying to reconstruct a date/time period from five data elements Year, StartMonth, StartDate, EndMonth, EndDate If the event starts on June 5 and ends on June 6, 2010 - The label would read June 5 thru 6, 2010. If the event starts on June 30 and ends on July 2, 2010 - the Label would read June 30 thru July 2, 2010. and if the event starts on June 5 and ends on June 5, 2010 - The label would read June 5, 2010. I've tried a few variations without success. This one comes closest to what I'm aiming for.

The Error
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
The Story
I've written a page outside of Visual Web Developer 2010 that uses a SqlDataSource object along with a FormView object that works perfect. Building upon those awesome skills I obtained I started to build a project within Visual Web Developer, this time creating an Empty Web Application and went along my happy way building my new site. I used the same techniques and almost the same code as before - just pointing to a different table but I was met with the aforementioned error message.
The Confusing part
Here's the puzzling part - if I take my page I wrote outside of Visual Web Developer, again - it works perfect - no complaints, and add it as a page to the project I've built it now presents the same error message and I have no idea why.
The Tests Completed
I've backed off of targeting .NET 4.0 framework and went to 2.0 as I am not using any specific 4.0 controls or methods at this time. I've taken my page that originally gave me issue and recreated it outside of a Visual Web Developer project and instead as a stand alone page and the exact same code - copy, cut, paste - works perfect!
I wasted the better part of the day on this and am no closer to a understanding the issue than what I was this morning.
I am looping through a set of objects and marking them for deletion. The 2nd one always causes the above exception. tb_invoice has a FK to tb_shipment.
As always, I am probably missing something very obvious, but I have stripped out so much from this code already that there is nothing left, and I am still getting this exception. This is a local SQL 2008 instance and there is of course nothing and nobody changing the invoice in between reading them and calling SubmitChanges().
myDataContext db = new myDataContext();
IQueryable<invoiceDetail> pendingInvoices
db.GetInvoiceDetailPending();
foreach (invoiceDetail id in pendingInvoices) {
tb_shipment s = db.GetShipmentById((Guid)id.shipment_id);
db.tb_invoices.DeleteOnSubmit(
db.GetInvoiceById(s.tb_invoices.FirstOrDefault().id)); }
SubmitChanges(); // fails for the 2nd invoice
}
I get this error message when I connect to the data source on localhostERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specifiedthe connection string is
connectionString="Data Source=DRIVER={MySQL ODBC 3.51 Driver};SERVER=localhost;PORT=3306; DATABASE=database;UID=xxx;PWD=xxx;OPTION=3;pooling=false;"
providerName="System.Data.SqlClient"
it must be some kind of problem in the environment since the connection string works on a remote server. I downloaded the driver and added it with the Data source (ODBC) application in the control panel.

I have a ASP.NET webapplication where I use ODBCConnection to connect a MySQL server, it will take the connectionstring from the web.config file and this works grate.
But when I put the same code in a WPF application and hardcode the same connection string I get the followin exception when runnint ODBCConnection.Open() :
Data source name not found and no default driver specified
I have checked the ODBCConnection orbject and its instansiated with the exact same connectionstring as in the webapplication.
The connection string looks like this :
"DRIVER={MySQL ODBC 3.51 Driver};SERVER=X.X.X.X;DATABASE=X;USER=X;PASSWORD=X;OPTION=3"
The X is set to propert values
I am running both from the same computer so the MYSQL ODBC connection is installed correct.

I'm having some really annoying issue using ADO.NET connector.
I've added reference to my project- the file "MySQL.data.dll"
Actually, i've copied the file from "MySQL Connector Net 6.2.2Assemblies" to "MyWebSitein" and then added reference.
Then, typed "using MySQL.data" and as you can guess, i've got that message:
Namespace or type specified in the Imports 'MySql.Data.MySqlClient' cannot be found.
