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."
The "User_x0020_Name" field does exist in the XML file. This is a portion of the XML file.
<?xml version="1.0" encoding="utf-8" ?>

I am displaying a table into a gridview for which I've a SQL query written which uses IF-ELSE condition. In one of the conditions, if the condition stands TRUE then one of the coloms should be eliminated from the table. But I constantly get an error:"A field or property with the name 'IXC_Vendor_Circuit_ID' was not found on the selected data source."

I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.

I have a dataview on a page. I am binding a list of Items, and each item has a Person object. So I get this exception "field not found in selected datasource" when I try to bind to any property on the person object.
[Code]....
It appears that the dataview is having problems with the person object because it will display all the properties for the Item correctly.
why I get a not found on the boundfield and not on the eval?

Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.

I have a DetailsView with some templates. I would like to bind a textbox in one of the templates to a field of a datasource which is not the datesource of the DetailsView. What is the syntax of the Bind() or Eval() code expression to do this, assuming it's possible?
Also where can I find some material on syntax of these "code expressions" and what can be in them?
I realize I'm missing something pretty basic here...

I'm sure it was discussed hundred of times, but maybe this time will elucidate some new points )
The question is: do I need to limit number of selected rows in data source for GridView?
When I use paging in GridView does limiting selected rows make GridView work faster?
Now I use ObjectDataSource with Linq in functions.
[Code]....
Does this make sense or I can just use LinqDataSource without thinking of selected rows?

I have an insert that uses an object data source with out the direction property set and it works fine. I noticed the direction property though and wondered if I should use it.Should the direction property for the parameters of an object data source be used with a simple CRUD operations?

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 just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:
[Code]....
My code behind, where I handle a button click event to get all values in rows w/ selected checkboxes:
[Code]....
Can I not use row.Cells[i]? The only thing Intellisense gives me that makes any sense is 'rows.Cells[i].Text'... not sure what else to do.

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.
