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.

Not sure what I'm missing
I am using Visual Studio 2010 for the first time. I program in MS Access for a long time at decide to move to the ASP world. My problem is that I design my first web .aspx default page with a simple data grid. I decided to connect the data via the business object data adapter. I use the Dataset designer to great the dataset. All looks well and works fine on my PC. But when moved to the server I get the Terror "The type specified in the TypeName property of ObjectDataSource not found".
From my reading for the past two days, it seems that something need to be define (a class of some sort) to let ASP know where to find the data adapter. If this is the case, then why did not Visual Studio 2010 did not automatically build the class in the appropriate BIN/ APP_CODE or Global directory and more importantly, why would it work fine on the PC , but not on the server. I am totally blind-sided by Visual Studio 2010 allowing me to design and test on PC but throws me a curl ball with moving to a server. Am I assuming to much from Visual Studio 2010???
What is the solution.. What I am looking for is to know where exactly where and how to write this class. I am so new to ASP, all of my reading just confusing me more and more by reading so many post on this error. I know it is probably a simple class to write somewhere, but why did not Visual Studio 2010 write it accordingly.
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."
View 6 RepliesI'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 create a script that changes its output based on a range of values. Here is what I mean:
I have a MSSQL database with an ASP scripted website that reads it and displays the data in a table. One of the columns in the database is a percentage and I want that column in the web page to have a background colour based on the figure outputted.
So each cell may be a different colour. If the number is between 0 and 30 then red background, 31 to 70 orange etc.
At the moment I have the database output script looking like this:

How can I implement what I have outlined above?
i have a sortedlist who values contain a Product objects. i wish to set the Quantity property of a selected Product object ( from gridview) when the Quantity field changes?
how do i compare whether the product row Quantity field in the gridview is the same as the Product Quantity property in the sortedlist and update accordingly?
note. i have converted to a list(of product) to bind to gridview. then update the sortedlist values
I'm using jQuery and setInterval method in my asp.net web application.
I call the webservice every 5 seconds in order to check for DB changes. When i see a change, i want to change the photo of the linkButton that located on the master page, but i can to that due to static constrains.
An object reference is required for the non-static field, method, or property 'System.Web.UI.Page.Master.get'
my c# code is:
[WebMethod()]
public static bool checkDBChange(string userId) {
DBConnection dbConnection = new DBConnection();
if (dbConnection.isChanged(userId)) {
((Site1)Master).SetImageUrl = "~/Icons/a.ico";
}
return false;
}
The SetImageUrl is a setter in my master page that sets the new url to the linkButton. How I can implement it?
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.
